Ubuntu 14.04 Installation Nginx+php+mysql

The previous period of tossing, quite a bit of trouble, the process found that many of the online information is older and outdated,
So here also simple to rearrange the process, to win a post to solve the problem.

Build Nginx, PHP, and MySQL environments based on the latest Ubuntu 14.04(September 2014)
All of the following command-line operations:

1, due to the need for a large number of permissions operations, temporary elevation of privileges, using the root account
sudo su

2, install the APT source management tool, add Nginx and PHP installation source
apt-get install python-software-properties
add-apt-repository ppa:nginx/stable
add-apt-repository ppa:ondrej/php5

3, update the system software
apt-get update

4. Install MySQL
apt-get install mysql-server
Note: During the installation process, you will be asked to enter the password for the root account of MySQL.

5. Installation of PHP and support for MySQL
apt-get install php5 php5-fpm php5-mysql php-apc

6, according to the actual needs, the optional installation of various types of PHP functional modules (specifically please Baidu)
apt-get install php-pear php5-dev php5-curl
apt-get install php5-gd php5-intl php5-imagick
apt-get install php5-imap php5-mcrypt php5-memcache
apt-get install php5-ming php5-ps php5-pspell
apt-get install php5-recode php5-snmp php5-sqlite
apt-get install php5-tidy php5-xmlrpc php5-xsl

7. Installing Nginx
apt-get install nginx

8. Configure PHP
vi /etc/php5/fpm/php.ini

Found it:;cgi.fix_pathinfo=1
Switchcgi.fix_pathinfo=0

9. Configure Nginx
mkdir /www
chmod 755 /www
Create a/www directory set to 755 permissions

vi /etc/nginx/sites-enabled/default

Found it:root /usr/share/nginx/html;
Switchroot /www;
Description: Set the Web site root directory to the/www directory, and be careful not to write/www/this format,
This habitual little neat freak brought me an unexpected disturbance, and I went on to elaborate.

Found it:index index.html index.htm;
Switchindex index.php index.html index.htm;
Description: Add index.php to the default index file

Found: location ~ .php$ { * } chunks
Make the following adjustments (changes are commented at the end of the line):

location ~ .php$ {
try_files $uri =404; #增加
fastcgi_split_path_info ^(.+.php)(/.+)$; #反注释
## NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini
#
## With php5-cgi alone:
# fastcgi_pass 127.0.0.1:9000;
## With php5-fpm:
fastcgi_pass unix:/var/run/php5-fpm.sock; #反注释
fastcgi_index index.php; #反注释
include fastcgi_params; #反注释
}

10, solve the php-fpm and Nginx small bug
Following the above steps, due to a small bug between Nginx and php-fpm, this phenomenon can be caused by:
The static page *.html in the website will be accessed normally, while the *.php file returns a 200 status code,
But the actual output to the browser page content is blank.

In short, the reason is that Nginx does not correctly pass the address of the *.php file to php-fpm to parse,
The equivalent of PHP-FPM received a request, but this request points to a nonexistent file, and returns an empty result.

In order to solve this problem, the Nginx default fastcgi_params configuration file needs to be changed:
vi /etc/nginx/fastcgi_params

Add a line at the end of the file:
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

For the contents of this line, say a few words, of which there are two parameters:
$document _root means the root directory of the website, that is, we have just set the root/www in front;
$fastcgi _script_name refers to each *.php file name on the website (in fact, the relative path of the files)
These two together form the complete PHP file path, such as your website has a/test/script.php file,
The full path that Nginx passes to PHP-FPM is:/www/test/script.php

I said in front of the configuration Nginx, written as root/www/; This is not a problem for nginx,
But when it passes PHP file paths to PHP-FPM, it forms:/www//test/script.php
This file address is invalid (not getting the correct php file), so there is a problem with the return blank.
The problem is so hidden that I spend a lot of time looking at log, finding information, and adjusting settings.

11, restart the services
service php5-fpm reload
service nginx reload
Reload the configuration changes.

12. Testing
vi /www/index.php
Content:
<?php echo phpinfo(); ?>

Please open your browser to access: http://localhost If everything works, it will output PHP environment information, such as:

Note: Don't use the so-called Chinese version that integrates a bunch of junk software.
