_php tutorial for specific steps based on Ubuntu nginx+php+mysql installation configuration

1 , update

1	sudo apt-get update

2. Installing nginx

1	sudo apt-get intsall nginx

the file structure of Ubuntu after installation is roughly :
* all configuration files are under /etc/nginx , and each virtual host is already scheduled for /etc/nginx/ Sites-available under
* Program Files in /usr/sbin/nginx * log in /var/log/nginx
* and already created a startup script under/etc/init.d/. nginx
* The Default virtual host directory is set to /var/www/nginx-default

Below you can start the nginx Look at the effect ( Please make sure that the port is not used by other services ):

1	Sudo/etc/init.d/nginx start

# or a simple

1	Service Nginx Start

Then open the browser and see http://localhost/ See If you see "Welcome to nginx! " If you see the , indicates successful installation .
Of course , There's no problem with this piece of cake . If the run is unsuccessful , can first

1	sudo killall apache2

Kill the Apache Process
3. Install PHP

sudo apt-get install php5 php5-cgi php5-mysql php5-curl php5-gd php5-idn php-pear php5-imagick php5-imap php5-mcrypt php5- Memcache php5-mhash php5-ming Php5-pspell php5-recode php5-snmp php5-tidy php5-xmlrpc php5-sqlite php5-xsl

4, installation spawn-fcgi
Why install spawn-fcgi , which is used to control the php-cgi process , to prevent a process from collapsing or the efficiency of a single process is too low .
Many people on the internet have said that to use spawn-fcgi must be installed lighttpd, In fact, not necessary , can be directly installed spawn-fcgi
Run :

1	sudo apt-get install spawn-fcgi

5. Configuration
The next is the most frustrating configuration .
Configuring Nginx and spawn-fcgi to run together
(1). in the /etc/nginx/fastcgi_params file Last , Join a row , can be used

1	sudo vi/etc/nginx/fastcgi_params

Join this line :

1	Fastcgi_param script_filename $document _root$fastcgi_script_name;

(2). In addition, you need to php-cgi the configuration file ( This profile is located in /etc/php5/cgi/php.ini on Ubuntu) in , Find Cgi.fix_pathinfo Options , modified to :

1	Cgi.fix_pathinfo=1;

This allows the php-cgi to use the script_filename variable normally .
(3). Open /etc/nginx/sites-available/default file in

123	server {listen 80;server_name localhost;

The absolute address of the Web root is added below , here is the default address of Nginx

1	Root/var/www/nginx-default

That is, the root and server_name peers, which is equivalent to the Apache default directory
If this is not the case , it is easy to execute the php file , it will prompt "no input File specified".
I've been around a great circle before I found out the problem . and then modify

123456

#location ~. php$ {#fastcgi_pass 127.0.0.1:9000; #fastcgi_index index.php; #fastcgi_param script_filename/scripts$ Fastcgi_script_name; #includefastcgi_params; #}

Modified into

1234	Location ~. php$ {fastcgi_pass 127.0.0.1:9000;fastcgi_index index.php;fastcgi_param script_filename/var/www/ Nginx-default$fastcgi_script_name;

Include/etc/nginx/fastcgi_params; # contains the fastcgi parameter file address
6. Start fast_cgi Process

1, sudo/usr/bin/spawn-fcgi-a 127.0.0.1-p 9000-c 5-u www-data-g www-data-f/usr/bin/php5-cgi-p/var/run/fastcgi-php. Pid

7. Set boot fastcgi process and start

1	sudo vi/etc/rc.local

Add next line

1	/usr/bin/spawn-fcgi-a 127.0.0.1-p 9000-c 5-u www-data-g www-data-f/usr/bin/php5-cgi-p/var/run/fastcgi-php.pid

If the Open php file appears : No input files specified Please check The configuration of php.ini

1	Cgi.fix_pathinfo=1

1

doc_root=

Also , each virtual machine according to their own different virtual machines set up a different directory , to ensure that the path is correct .
Check the configuration file under /etc/nginx/sites-available , the server contains root and address rather than Location within the Root
Start

1	Fast-cgisudo/usr/bin/spawn-fcgi-a 127.0.0.1-p 9000-c 5-u www-data-g www-data-f/usr/bin/php5-cgi-p/VAR/RUN/FASTCG I-php.pid

The

parameter means the following
*-f Specifies the execution location of the process that called FastCGI , According to the system installed on the PHP case Specific Settings
*-a bind to address addr
*-P bind to port Port
*-S bound to the path of the UNIX socket path
*-C Specifies the resulting FastCGI Number of processes , default to 5 ( for PHP only)
*-P Specifies the resulting process's PID file path
*-u and -G FastCGI What identity is used (-u user -G user Group ) run , under Ubuntu , you can use www-data, other configurations as appropriate , such as Nobody , Apache , etc. you can now have a probe or in the Web root directory PHP file test it
8 , install mysql

1	sudo apt-get install mysql-server mysql-client

The middle will prompt for the Root user password , and then enter it .
Start MySQL

1	Sudo/etc/init.d/mysql start

Test that the MySQL service is working :
Run

1	Mysql-uroot-p

Enter mysql password

1	show databases;

If you see the following content
| Database |
| Information_schema |
| MySQL |
Then MySQL is installed correctly .
At this point , the nginx+php+mysql under ubuntu is installed .
