Installation and configuration of Nginx under CentOS

Preface:

First introduce Nginx:

Nginx is a lightweight Web server/reverse proxy server and e-mail (IMAP/POP3) proxy server that is released under a bsd-like protocol. It is characterized by the possession of less memory, concurrency is strong, in fact, nginx concurrency is actually in the same type of Web server performance better.

Specific installation details are described below:

1. Install the Dependencies and Software toolkit before installing Nginx: (If the system has a toolkit that ignores this step, you can enter a command at the command line to test whether the command is available)

(1) Install make:

# yum-y Install gcc automake autoconf libtool make

(2) Installation g++:

# yum Install gcc gcc-c++

Other command kits, such as tar, do not have a self-download installation.

2. Install development team and dependent software packages (development tools, server platform development)

# yum Groupinstall-y "Development Tools" "Server Platform Development"
# yum Install-y openssl-devel Pcre-devel

3. Start installing Nginx:

First add the user Nginx, to run the Nginx service process:

# groupadd-r Nginx

# Useradd-r-G Nginx

Then use wget to download the Nginx compressed package directly from the Internet:

# yum Install wget

# wget http://nginx.org/download/nginx-1.4.7.tar.gz

After decompression, compile: Enter the directory first

# Tar XF nginx-1.4.7.tar.gz

# CD nginx-1.4.7

Then start compiling and installing:

# ./Configure--prefix=/usr--sbin-path=/usr/sbin/Nginx--conf-path=/etc/nginx/nginx.conf--error-log-path=/var/log/nginx/Error.log--http-log-path=/var/log/nginx/Access.log--pid-path=/var/run/nginx/Nginx.pid--lock-path=/var/lock/Nginx.lock--user=Nginx--group=Nginx--with-Http_ssl_module--with-Http_flv_module--with-Http_stub_status_module--with-Http_gzip_static_module--http-client-body-temp-path=/var/tmp/nginx/client/   --http-proxy-temp-path=/var/tmp/nginx/proxy/   --http-fastcgi-temp-path=/var/tmp/nginx/fcgi/   --http-uwsgi-temp-path=/var/tmp/nginx/Uwsgi--http-scgi-temp-path=/var/tmp/nginx/scgi--with-pcre

And then:

# Make && make install

4. Provide SYSV init script for Nginx

Create a new file/etc/rc.d/init.d/nginx with the following content:

#!/bin/SH# # Nginx-This script starts and stops the Nginx daemon## chkconfig:- -  the# Description:nginx is an HTTP (s) server, HTTP (s) reverse # Proxy and IMAP/POP3 proxy server# processname:nginx# config:/etc/nginx/nginx.conf# config:/etc/sysconfig/nginx# pidfile:/var/run/nginx.pid# SourcefunctionLibrary:/etc/rc.d/init.d/functions# Source Networking configuration:/etc/sysconfig/network# Check that networking are up.

Then give execute permission for this script:

# chmod +x/etc/rc.d/init.d/nginx

Add to the service management list and let it boot automatically:

# chkconfig--add Nginx

# chkconfig Nginx on

5. Add environment variables and test

# yum Install vim
# vim/etc/profile.d/nginx.sh
Export path=/usr/local/nginx/sbin/: $PATH

Then start the service and test:

# service Nginx Start

Enter the server IP address on the website: http://172.16.16.173/

6, the PHP configuration into the human nginx:

First configure the Nginx nginx.conf file:

Enter under Terminal: # Find/-name nginx.conf

Locate the nginx.conf configuration file and use Vim to enter the modification: (yum installs vim download and install if no VIM is available)

Then add the following content to the server:

Location ~ \.php$ {              root         /usr/html;              Fastcgi_pass   127.0. 0.1:9000;              Fastcgi_index  index.php;              Fastcgi_param  script_filename  $document _root$fastcgi_script_name;              Include        fastcgi_params;          }

The yellow section is a web-hosted directory that can be accessed directly in the browser.

also note that the PHP must be compiled to ensure that the system has LIBXML2 and Libxml2-dev both packages, because PHP by default will compile XML functionality, so XML support is essential.

So use: # yum install LIBXML2

# yum Install Libxml2-dev download installs the dependent package.

Then enter the/usr/html directory, vim test1.php, for editing:

<? PHP     Echo "TEST by Still";     Phpinfo ();? >

To restart the Nginx service:

# service Nginx Restart  

Then view the results in the browser:
