Use nginx to build a high-performance WEB Environment

Nginx ("engine X") is a high-performance HTTP and reverse proxy server and an IMAP/POP3/SMTP proxy server. Nginx was developed by the rambler.ru site with the highest access volume in Russia as Igor Sysoev. It has been running on this site for more than two and a half years. Igor publishes source code in the form of a class BSD license.

Nginx surpasses Apache's high performance and stability, making it more and more websites using nginx as web servers in China, including portal website channels such as Sina Blog, Sina podcast, and Netease news, discuz! Well-known forums such as official forums and the Shui Mu community, and emerging Web 2.0 websites such as Douban, yupoo album, domestic SNS, and thunder online.

Start the Database Service and add it to auto-start
#/Usr/local/MySQL/bin/mysqld_safe -- user = MySQL &
# Cp support-files/MySQL. Server/etc/rc. d/init. d/mysqld
# Chmod 755/etc/rc. d/init. d/mysqld
Add to auto start service queue:
# Chkconfig -- add mysqld
# Chkconfig -- level 345 mysqld on
Add Root Password
#/Usr/local/MySQL/bin/mysqladmin-u Root Password "123456"
Test:
#/Usr/local/MySQL/bin/MySQL-u root-P
Enter the password 123456 to check whether the database can be accessed.

Configure the library file search path
# Echo "/usr/local/MySQL/lib/MySQL">/etc/lD. So. conf
# Ldconfig
# Ldconfig-V

# Echo "Export Path = $ path:/usr/local/MySQL/bin">/etc/profile
# Source/etc/profile
4. install PHP
An executable file is generated here, which is different from Apache. When combined with Apache, a dynamic library is generated.
# Tar-jxvf php-5.2.6.tar.bz2
# Gzip-CD php-5.2.6-fpm-0.5.9.diff.gz | patch-D php-5.2.6-p1

(1) <value name = "listen_address"> 127.0.0.1: 9000 </value>
Change to <value name = "listen_address"> IP: 9000 </value> // The default 127.0.0.1 is used on the local machine.
(2) Remove comments and modify the following two lines.
<Value name = "sendmail_path">/usr/sbin/sendmail-t-I </value>
<Value name = "display_errors"> 1 </value>
(3) <value name = "user"> nobody </value> // uncomment
(4) <value name = "group"> nobody </value> // uncomment
(5) <value name = "allowed_clients"> 127.0.0.1 </value> // the PC to be connected to. This local machine uses 127.0.0.1.
Start PHP-FPM
#/Usr/local/PHP/sbin/PHP-FPM start
Add to auto-start
# Echo "/usr/local/PHP/sbin/PHP-FPM start">/etc/rc. Local

5. Modify the nginx configuration file and support PHP
# Vi/usr/local/nginx/CONF/nginx. conf

}
Note:
The server part is a php vm.
127.0.0.1: 9000 is a FastCGI PC. The local machine I use here

Test configuration file:
#/Usr/local/nginx/sbin/nginx-T

6. Optimize Linux Kernel Parameters
# Vi/etc/sysctl. conf
Add the following content at the end:
Net. ipv4.tcp _ fin_timeout = 30
Net. ipv4.tcp _ keepalive_time = 300
Net. ipv4.tcp _ syncookies = 1
Net. ipv4.tcp _ tw_reuse = 1
Net. ipv4.tcp _ tw_recycle = 1
Net. ipv4.ip _ local_port_range = 5000 65000

Make the configuration take effect immediately:
#/Sbin/sysctl-P
