First, the installation of nginx
Local environment: centos-x86 6.5 nginx-1.10.2
1. Install the pcre library
yum install –y make zlib-devel openssl-devel pcre-devel
ubuntu system:
apt-get update
apt-get install libpcre3 libpcre3-dev
apt-get install zlib1g-dev
apt-get install openssl
2. Install GCC and GCC-C++
yum install gcc
yum install -y gcc gcc-c++
ubuntu system:
apt-get install build-essential
apt-get install libtool
3. Install ngx_cache_purge-2.3
Official website: http://labs.frickle.com/nginx_ngx_cache_purge/
G 名 ： ngx_cache_purge-2.3.tar.gz tar zxvf ngx_cache_purge-2.3.tar.gz
Put the decompressed folder in the same directory as the nginx decompressed file
3. Install nginx (prefix specifies the nginx file installation path, with specifies the installed plugin
The role of the ngx_cache_purge module: used to clear the cache of the specified url)
tar zxvf nginx-1.10.2.tar.gz
cd nginx-1.10.2
./configure --prefix=/usr/local/nginx --with-http_ssl_module --with-http_gzip_static_module --with-http_stub_status_module --add-module=../ngx_cache_purge-2.3
make && make install
4. Write a startup script
[root@localhost ~]# vi /etc/init.d/nginx
#!/bin/bash
# chkconfig: 345 99 20
# description: Nginx servicecontrol script
PROG="/usr/local/nginx/sbin/nginx"
PIDF="/usr/local/nginx/logs/nginx.pid"
case "$1" in
start)
$PROG
echo "Nginx servicestart success."
;;
stop)
kill -s QUIT $(cat $PIDF)
echo "Nginx service stopsuccess."
;;
restart)
$0 stop
$0 start
;;
reload)
kill -s HUP $(cat $PIDF)
echo"reload Nginx configsuccess."
;;
*)
echo "Usage: $0{start|stop|restart|reload}"
exit 1
esac
5. Start
[root@localhost ~]# chmod +x /etc/init.d/nginx
[root@localhost ~]# service nginx restart
[root@localhost ~]# chkconfig --add nginx
[root@localhost ~]# chkconfig nginx on
Second, modify the configuration file
worker_processes 4;
#error_log logs/error.log info;
events {
#Use the epoll model to improve performance
use epoll;
#Number of connections in a single process (maximum number of connections = number of connections * number of processes)
worker_connections 65535;
}

#File extension and file type mapping table

#default file type

#Enable efficient file transfer mode. The sendfile instruction specifies whether nginx calls the sendfile function to output files. For ordinary applications, set it to on.
#If it is used for applications with heavy disk IO load such as downloading, it can be set to off to balance the processing speed of disk and network I/O and reduce the load of the system.
#Note: If the picture is not displayed properly, change this to off
sendfile on;
#Long connection timeout, in seconds
keepalive_timeout 65;
#gzip is to tell nginx to send data in gzip compressed form. This will reduce the amount of data we send.
gzip on;
gzip_min_length 1k; #Minimum 1K
gzip_buffers 16 64K;
gzip_http_version 1.1;
