linux+nginx+php set up high-performance Web server _linux

Nginx ("Engine X") is a high-performance HTTP and reverse proxy server and a IMAP/POP3/SMTP proxy server. Nginx was developed by Igor Sysoev, the second rambler.ru site for Russian traffic, which has run over 2.5 at the site. Igor releases the source code in the form of a BSD-like license. Although still beta, Nginx has been known for its stability, rich feature sets, sample configuration files, and low system resource consumption.

Nine, configure boot automatically start Nginx + PHP

Vi/etc/rc.local

Add the following at the end:

Ulimit-shn 51200
/USR/LOCAL/WEBSERVER/PHP/SBIN/PHP-FPM start
/usr/local/webserver/nginx/sbin/nginx

X. Optimizing Linux Kernel Parameters

Vi/etc/sysctl.conf

Add the following 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

To have the configuration take effect immediately:

/sbin/sysctl–p

Do here, you can reboot restart Linux, no accident should be able to open the nginx smoothly

Smooth restart Nginx

Ps aux | grep nginx
Find Nginx Master process, if: 5800, then kill
Kill–hup 5800

Smooth reboot PHP

/USR/LOCAL/WEBSERVER/PHP/SBIN/PHP-FPM restart

Other commands for PHP-FPM: Start | Stop | Quit | Restart | Reload | Logrotate
