How to setup your own Invoice Ninja server with $2.5/mo budget

My friend ask me to test Invoice Ninja on my server. This software is very popular since you can do many things with invoice. This software made with Laravel 5.2 and I’ve test it ‘hard way’ in my vps .I think I can share simpler way to get this software run in affordable vps.

This documentation using Vultr vps smallest server and serverpilot free account. In nutshell, you have great invoice software with free control panel ūüôā

Lets get start!

Setup VPS Server

VPS provider is Vultr. They provide the plan with pricing $2.5/month.

I use Ubuntu (14.04 64 bit) with following specs : 512MB and 20GB SSD storage.

After hit deploy button write down these information :

  1. Ip address
  2. username (root)
  3. password for vps server

Setting URL for access Invoice Ninja

I use Simple Zone Editor from my cpanel hosting to set A record for subdomain http://ninja.hostingformula.net

update :

I change my dns manager to cloudflare.

$ dig ns hostingformula.net

How to transfer self hosted vps wordpress to cpanel hosting

Another case for hostingformula presented by my brother ūüôā . He use vps for his blog that backed by wordpress. Not critical blog actually. He use it for daily ramblings and so on. Unfortunately his vps expire and he already get cpanel hosting for his next place. He ask me to transfer his blog as soon as possible.

The plan for his blog are :

Request for ssh access

Many cpanel hosting support ssh but this feature not enabled by default. You have to open a ticket and ask for activate ssh access for your cpanel account. Note : every hosting company have different policy including ssh port. Usually its not 22 but you ask for exact port for sure.

Use scp

My brother cpanel hosting is very limited in space. He’s current use around 400 MB and his cpanel hosting space is 500 MB. Very tight huh ūüôā . Scp come for rescue in this case. The exact command for scp transfer from vps to cpanel :

scp -P 24579 -r wp-content [email protected]:.

24579 is ssh port  (your webhosting ssh port is vary)

-r is recursive mode transfer

wp-content ; wordpress heavily use wp-content folder to store plugins, uploaded image, backup etc. I need only this folder as I can download latest wordpress code from wordpress.org .

Fix Permission

Many cpanel hosting use suphp . You’ll need to fix permisson for folder (755) and files (644) or you’ll get annoying error message when you access your wordpress blog.

Quick commands :

find wordpress_folder/ -type d -print0 | xargs -0 chmod 0755

find wordpress_folder/ -type f -not -name “*.pl” -not -name “*.cgi” -not -name “*.sh” -print0 | xargs -0 chmod 0644

Done. The plan is complete now ūüôā

Maybe I’ll let my brother to do it himself now and I’ll check his work.

Bonus Plan

To avoid downtime he need to set cloudflare account and activate it for dns only. When everything is fine then he can activate proxy function.

Fix Crawl 404 Error on Google Search Console

I just find out that one of my blog got hacked. The intruder put a file in wp-content directory and cause 404 error .

What I’ve done to fix this error :

  1. Delete the page ; xx-data.php
  2. Select all error from google search console and click ‘Mark as Fixed’
  3. Request xx-data.php removal from Google index

haacked_page

Let see if I see another error. Will update this post soon.

Fix MySQL 113 error

Yesterday I got 113 error code from MySQL when I try to test access it from network.

The machine have 2 lan cards (192.168.103.254 and 192.168.1.89). Both of them are active and I can ping it.

# mysql -ualam -p -h 192.168.103.254
Enter password:

Enter password:
ERROR 2003 (HY000): Can’t connect to MySQL server on ‘192.168.1.89’ (113)

After see the major.io post about MySQL error codes . I find out that the problem might came from firewall.

Check current firewall state :

# cat /etc/sysconfig/iptables

Well, this line :

-A INPUT -j RH-Firewall-1-INPUT

is the source of problem. Edit the order of rule and restart iptables.

Cpanel tip : Speed up your wordpress with proper PHP version

I don’t have much money for using expensive web hosting or vps or dedicated server for my wordpress blog. Is there any way to speed it up without touch plugin or something else?

Well, using cache is the best way to achieve blazing fast wordpress but one trick I found is using proper PHP version.

Yes, using latest PHP version is dead simple way to make wordpress faster.

By default cpanel user don’t get latest version, for example in my cpanel I see this :

php-cpanel1

For latest PHP version you can refer to php.net site :

php-cpanel2As you can see there are 3 version :

  1. PHP 5.6.11
  2. PHP 5.5.27
  3. PHP 5.4.43

Since I use cpanel I can not compile nor install latest PHP version as I used to using VPS but I can use closest version to 5.6.11.

Click “select php version” under software and services menu.

php-cpanel3

By default native php (the ones that come with server operating system) will be shown.

php-cpanel4

Choose 5.6 from drop down and click save as current.

php-cpanel5

Of course you can choose extensions. Only use the one that you use. For example if you only use mysql then you need to disable pgsql (postgresql) from extension.

How do I know if I already use PHP 5.6?

Create new file using file manager facility and save it as coba.php with these lines :

<?php

phpinfo();

?>

save and open from web browser. If you see like this one then your previous configuration is working well.

php-cpanel6

How to enable phalcon php in cpanel shared hosting

Long time not see you guys ūüôā . Being busy with new toys called Phalcon PHP . Yes, this tool is very awesome in my opinion and I use it with my vps. Since this blog also run in vps so I just surprise when I see PhalconPHP also supported in cpanel hosting that I also use.

Yes, namecheap also enable PhalconPHP in their shared hosting package.

How do I know if PhalconPHP work in my cpanel?

Create simple file :

Login to cpanel and click ‘File Manager’ -> New File

phal1

Enter these lines :

<?php
phpinfo();
?>

save the file and access it online.

By default you will not see PhalConPHP extension enabled.

Change PHP version and enable PhalCon PHP extension for Cpanel

Click “Select PHP version”

phal3

Select PHP 5.5 and set this version as current.

Then choose ‘phalcon’ from extension supported list.

phal2

 

Click save.

Then you have working Phalcon PHP support.

Current usage in my namecheap account.

phal4

 

Time to fly with phalcon ūüôā

For vps, you refer to this post. (install multiple php on ubuntu 16.04 vps).

 

 

 

 

WordPress and Cpanel main domain

Last Cyber Friday 2014 I got chance to try namecheap hosting. Its shared hosting package that normally priced $9,88/year . The price is only for 1st year but worth to try since I only got it for $0,98. The price is very good but since people often neglect it I prefer to act vice versa. I’ll use this hosting package for my family blog.

Domain and Sub Domain

The blog itself consist from :

1. Main domain

2. 4 sub domain but my wife told me to only activate 3 sub domain.

Size

Size of family blog (main domain + all sub domain is around 500 MB) in zip format.

$ du -sh zip
508M    zip

Traffic

The traffic is not big :

– less than 100 uv (unique visitor) for main domain

– less than 1000 uv for all sub domain (my wife blog is more famous than my blog hahaha). More

How to resolv looping error after change server

Hostingformula currently switch to cheap vps server. Old hosting provider using cpanel and everything went fine . Almost perfect in migration process except one thing.

I forgot about cloudflare.

cloudflare-vps-looping

Yes. I forgot if I enable cloudflare for this domain and the result is bad. Looping error caused by www mapping that set automatically by cloudflare kill this blog.

Solution for this kind of error is simple :

1. Disable cloudflare for your domain by visit cloudlfare or

2. Visit cpanel, click Simple DNS setting and ‘delete’ any entry related to cloudflare (see picture above for example).

How to test if the problem disappear?

Problem left after this action is dns propagation. You can install vpn software like hotspotshield or related to try visit your blog / website again.

3. Use intodns to verify the dns change. If intodns told you right ip address then you’re on right track.

4. Patient. Other problem left is client dns. Since you can not force client to use google or opendns for resolve your new server the only option is be patient.

How to move Joomla website to VPS

A friend of mine that not seen for years contact me. He had problem with his school website. Headmaster give him order to take care their website that seem to abandoned by current holder. Every time they (school) contact him. No respond and no email. He ask me to see it and if possible solve it immediately.

Update : if you’re in hurry then you can use Fiverr service that will do the job ($5 per site). Click here to see the service.

After ask the website hosting representative we have clues where do we must start.

  1. Create official letter from school about domain ownership.
  2. Scan the letter and send it to hosting company

The process itself is not straightforward as current holder respond to hosting company email and the phone but not respond to us. After a month the progress finally move to right direction. Current holder not paid for hosting fee and that’s the reason for my friend. Contact hosting company and finally they approve account moving and switching.

Since the hosting company suspend the account for its late payment then the website is not accessible anymore and only display ‘account suspended’ message. My friend ask me if I can give him temporary place for their school. I agree to give him a space with exchange. I must do the transfer process myself. I like to see how to transfer joomla based website to vps.

Lets get start!

Backup Joomla Website

Fortunately my friend already download the backup file. Its tar.gz file (backup-11.15.2014_11-29-19_domain.tar.gz ).

Send Joomla backup file to vps

After copying the file to my laptop I initiate transfer using scp.

scp backup-11.15.2014_11-29-19_domain.tar.gz [email protected]:/root

the process depend on internet speed and file size. For my case, it took around 1 hour to upload 132MB of file.

Creating New Domain on VPS

I use Easyengine that I use in previous post for host wordpress. Joomla also created with php and utilize mysql. So I choose php+mysql website.

# ee site schooldomainname --mysql

The command will generate all required files including database plus its credentials at /var/www/schooldomainname/ee-config.php

To see database name, database user database password and database host created by easyengine you can use :

cat /var/www/schooldomainname/ee-config.php

Extract Joomla Backup on VPS

I use same VPS that powered by Vultr for WordPress. Time for extract backup file.

# mv backup-11.15.2014_11-29-19_schooldomainname.tar.gz /var/www/schooldomainname/

# cd /var/www/schooldomainname/

# tar xvzf backup-11.15.2014_11-29-19_schooldomainname.tar.gz

# ls
addons     cron          fp              httpfiles  meta  mysql             pds              psql_users.sql    resellerpackages  shell      sslkeys      userdata  vf
bandwidth  digestshadow  has_sslstorage  locale     mm    mysql-timestamps  proftpdpasswd    quota             sds               ssl        suspended    va
counters   dnszones      homedir         logaholic  mma   mysql.sql         psql             resellerconfig    sds2              sslcerts   suspendinfo  vad
cp         domainkeys    homedir_paths   logs       mms   nobodyfiles       psql_grants.sql  resellerfeatures  shadow            ssldomain  userconfig   version

Looks like this backup file created by my friend taken from cpanel backup wizard.

I just need to find out where joomla files and its database located.

Finding Joomla Files + Database

After search for while I can see where is the location of Joomla files. Its in :

homedir/public_html

Database file located in :

mysql

Move Joomla folder to Easyengine public folder

Next step is move joomla folder found from previous step to easyengine folder.

#cd /var/www/schooldomainname

# mv backup-11.15.2014_11-29-19_schooldomainname/homedir/public_html .
# mv tes/backup-11.15.2014_11-29-19_schooldomainname/mysql/schooldomainname.sql .

Edit configuration file of Joomla

The configuration file located in configuration.php . Edit $user, $password and $db .

#nano htdocs/configuration.php

save the file.

Import Joomla Database File

# mysql -udb_user -p db_name < schooldomainname.sql
Enter password:
#

Make Joomla website live

# ee site enable schooldomainame

Thats it. Try to reload it via web browser and everything load fine so far.

My friend happy with the migration process. The load speed is incredible and they can add their content again and if they like it then they can make their own server with Vultr.

Lesson learned :

  1. Never use personal email address as contact, billing etc for school domain. Always use school email address. Beside this touch make everything official also prevent future problem like my friend case.
  2. If possible use the longest period for registering school domain. Yearly renewed domain is not suitable for a school.

Cheap Forex VPS Do it Yourself Server

One of my reader shout me an email about his problem. He get free forex vps from his broker after he met required deposit amount but he got disappointed with the quality. Its low end vps that running Windows 2003 and restrict him on EA usage. He don’t know how his broker monitor his vps but when he try to use his VPS running EA for another broker the connection get worst and he got warning. He must utilize the server only for the broker who give him vps not for others. He already search for cheap forex vps but still not sure which one he must choose. Lightweight vps he ever try is not run anti virus and very minimal installation. Only Windows 2003 with built in IE browser. To many networking problem and maintenance force him to abandon his server.

Another consideration is Windows Server 2003 end of life that will happen on July 14, 2015. While newer version need more requirement that mean more money when you deploy newer Windows server. Yes, according to Microsoft Technet the requirement for Windows 2003 server is quite low (x86 based computer need 256 MB recommended minimum and 512 MB minimum for x64 based computer). I think that the only consideration why many forex vps provider out there still deploy this version.

Since he only need stable and cheap vps server for his forex activity he want me to give my opinion. Is he can build his own forex vps server that also easy to use like Windows. I agree to answer and promise him to make a post for his question when time permit. After 2 weeks when I have time I start test possibility of using other operating system other than Windows as Forex vps. I came with conclusion : Yes, he can. He can build his own server and I think the server is stable too. More

How to recover email service (google apps) after downtime

One of our friend domain is down due to web hosting problem. Main domain of hosting service is not renewed at proper time and the contact person is not responding. Two things that need to get recovered:

1. Domain and email service

2. Website file and database

Since we don’t know where is the main host reside then nearest option we have is recover email service that fortunately using google apps. Another fortune we have is domain access is in my control so I can recover it quickly. Here the steps :

Update name server to new one

Since the domain registrar is namecheap I can easily use namecheap nameserver. Simply by click :

Domain Name -> Transfer DNS to Us

Change MX record to Google Apps setting

Click Host Management -> Mail Settingssetting google apps record on namecheap

Pick “User” and Choose “automatically set MX records necessary for Google Apps Email.

Save changes.

Click Save changes one more time.

choose mx record to point only for google apps

At this time namecheap will update mx record and user can relax now. Waiting for propagation time (maximum 3 x 24 hours).

You also able to verify setting by using intodns service.

Enter domain name and click report button. Pay attention for result, specially on MX section. If you also see like this one then everything is fine.

mx record result viewed from intodns side

Another work to do after this work is pointing A record to my vps for temporary service.

Softaculous Tips for WordPress Installation

wordpress_tips1Common problem that exist for ‘hack attack’ on wordpress are :

1. Old wordpress version

2. Using old theme

3. Using old plugins

Those 3 factors combined together and lead to ‘unstable’ self hosting wordpress.

Newest wordpress offer automatic upgrade for the version but you must do the rest (upgrading theme and plugins).

Those issue corrected by Softaculous. If you want to install new blog I suggest you to use these settings :

1. Database name : enter your blog name as component. ex, if your blog is about flower then fill flowerdb or mydbflower. It will save you from headache in the future.

2. Table prefix : enter shortname of your blog, ex: flo_ . Don’t use wp_ .

3. Use strong password. You can click ‘key’ icon next to admin password input.

4. Use advanced option. Make sure to check 3 options (auto upgrade, auto upgrade wordpress plugin and auto upgrade wordpress theme).

Using that setting will give you ‘health’ wordpress that give you long run blogging platform without worrying about late update action.

How about existing blog?

I’ll create separate post to explain it in step by step mode.

How to Install DragonFlyBSD in VPS using custom iso feature

Distrowatch told me about newest version of DragonFlyBSD (3.8.0) . This version also in my waiting list as I know this BSD variant since beginning. When DragonFlyBSD begin using ports¬† aka dports to their software installation management then I’m happily use this version as server.

For documentation process when I delegate installation process for my staff I create this simple guide.

Of course its VPS based as we try to minimize physical server for our company ūüôā

Create temporary iso location

DragonFlyBSD provide .iso.bz2 link and I have to convert it to .iso first. The idea is create temporary location for iso file and use it for Vultr custom iso.

I think my lowendspririt vps is good place to hold temporary image.

Moving users folder and create symlink

Today I got “error, can not write” message on the bottom of my blog. I think its temporary since I often see the message before (with bluehost).

This afternoon I got another message that confirm me if the message is not usual one. The message is sign of storage full. Yes, the blog move to vps and after checking the status :

# df -H
Filesystem      Size  Used Avail Use% Mounted on
/dev/vda1       8.4G  7.9G     0 100% /
none            4.1k     0  4.1k   0% /sys/fs/cgroup
udev            511M  4.1k  511M   1% /dev
tmpfs           105M  410k  104M   1% /run

none            105M     0  105M   0% /run/user
/dev/vdb1        22G   47M   20G   1% /data
# cd /

My VPS utilize 100% of / partition (I thought soft limit is there) and lead me to error message.

I forgot if this VPS use two drive : /dev/vda1 for operating system and /dev/vdb1 for data storage.

To fix the problem I just need to move content from /dev/vda1 to /dev/vdb1

# mv /srv/users/ /data/
# ln -s /data/users /srv/
# ls -l /srv/

total 0
lrwxrwxrwx 1 root root 11 Jun 15 14:56 users -> /data/users

Checking current status now :

# df -H

WordPress Featured Image

“I already upload photo for my post but I see blank display on our website”. That question came from my friend who work as webmaster. He is responsible for updating the news on the office website. I promise to take a look and tell you the answer. Actually I was buying time to figure out what caused the problem.

The site has been running for more than 2 years and no significant problems during this period. That changed only version of wordpress.¬† I think the reason why the picture features running on the website of my friend’s office was not functioning properly is wordpress.

After look around finally I can reproduce the problem and came back with answer ūüôā
