Just one script to install and optimise Nginx,mysql and php5 ,php-fpm for 128/512Mb VPS/Cloud instance.

Download

svn co https://github.com/junedmunshi/SampleCode/trunk/web/vpsSetup

OS

Tested on vanilla ubuntu 12.04 .

Install and setup

chmod +x vpsSetup.sh

chmod +x start.sh

chmod +x stop.sh

sudo ./vpsSetup.sh

To start server

sudo ./start.sh

To stop server

sudo ./stop.sh

But before you run the script

_Before you blindly run the script, you should look at configuration files for Nginx and modify it according to your need._ __Everything should work off the shelf except modifying few parameters in ./nginx/default .__ _Read Nginx section below._

Moreover, you can also change configuration for mysql and php if given configuration file does not suit to your need.Read Mysql and Php5 section below.

What will the script do?

It will, 
1) Add required debian repository

2) Install all required packages ( nginx mysql-server mysql-client memcached php5 php-apc php-auth php-net-smtp php-net-socket php-pear php5-curl php5-gd php5-mcrypt php5-mysql php5-fpm php5-memcached php5-tidy vsftpd )

3) Take backup of original mysql configuration file. ( /etc/mysql/my.cnf -> /etc/mysql/my.cnf.org)

4) Optimise mysql by patching configuration file from ./mysql/my.cnf to /etc/mysql/my.cnf

5) Apply same step as 3 and 5 for nginx and php5

Files Detail

* vpsSetup.sh : Installation script * mysql/my.cnf : MySQL server configuration file tuned for 512Mb server running mysql and nginx * nginx/nginx.conf : Nginx server configuration file tuned for 512Mb server running mysql and nginx * nginx/default : Configuration file for your web application.It will patched to /etc/nginx/sites-available . * php5/fmp/php.ini : See the php section below * php5/fmp/php-fpm.conf : See the php section below * php5/fpm/pool.d/www.conf : Tuned for 512Mb server.

If services do not start after applying optimal settings

1. If Nginx does not start , it may be possible that there is something wrong with either /etc/nginx/ngnix.conf or site-available/default. Run _sudo service nginx start_ and look for error. 2. If MySQL does not start , please check MySQL troubleshoot guide.[http://junedmunshiblog.blogspot.in/2013/05/troubleshooting-mysql.html](http://junedmunshiblog.blogspot.in/2013/05/troubleshooting-mysql.html)

Nginx

1)nginx/default
It is your web application configuration file. Current settings are configured for php, fast cgi and cakephp .

Things to check before you deploy:

port   
servername : your domain name   
root : path to your website code 
access_log and error_log : very useful for debugging your website code (not nginx) 
location : control behaviour for specific locations such "/" or "*.js,*.css,*.jpg (any assests)"

Note:

  1. Following line is not required if you are not using cakephp. Following line ensure that images,css etc. will load properly without generating "path not found " error from theme/plugin.

    try_files $uri $uri/ /../plugins/$1/webroot/$2/$3 /../View/Themed/$2/webroot/$3/$4 ;

Ref: http://lennaert.nu/2011/01/21/cakephp-performance-rewrite-plugin-assets-in-nginx/

  1. You may want to turn of access_log and log_not_found for images,xml etc. files once your site functions properly.
2)ngnix.conf

MySQL

my.cnf

1 You may consider further tuning following parameters under '[mysqld]' section if current settings are not best fit for you.

   key_buffer = 16K  	 (Default is 16M)   
   max_allowed_packet = 1M  (Default is 16M)    
   thread_stack = 64K    	 (Default is 192K)   
   thread_cache_size  = 4	 (Default is 8)

2 Innodb

  Disable if not needed.uncomment #skip-innodb

2 Fine tune if you are using it.

   innodb_buffer_pool_size = 16M  	     (Default is 128M)  
   innodb_additional_mem_pool_size = 2M

PHP

1) ./php5/fpm/php.ini

The only difference between original and patch file is as below.

;cgi.fix_pathinfo=1 -> cgi.fix_pathinfo=0
2) php5/fpm/php-fpm.conf
Blindly copied from http://www.axelsegebrecht.com/how-to/install-nginx-apc-varnish-wordpress-and-w3-cache-128mb-vps/#Configuring_PHP5-FPM
3) php5/fpm/pool.d/www.conf 
php_admin_value[memory_limit] = You can increase if you have more RAM
php_value[upload_max_filesize] = Change it otherwise leave it if you don't care
php_value[max_execution_time] = Change it otherwise leave it if you don't care
user = www-data 
group = www-data
