安装必须插件：
yum install gcc-c++ autoconf automake
yum install zlib zlib-devel opensslopenssl--devel pcre pcre-devel
安装nginx：
./configure
make
make install
关闭防火墙或添加配置项：
service iptables stop
chkconfig iptables off
检查配置文件是否正确：
/usr/local/nginx/sbin/nginx -t -c /usr/local/nginx/conf/nginx.conf
启动nginx：
cd /usr/local/nginx/sbin
./nginx
查询进程号：
ps -ef | grep nginx
停止进程：
/usr/local/nginx/sbin/nginx -s quit
重启：
/usr/local/nginx/sbin/nginx -s reload
测试：
测试端口：netstat -na|grep 80
浏览器中测试：http://ip:80
修改Nginx的配置文件nginx.conf，内容如下，实现反向代理负载均衡：
#user nobody;
worker_processes 2;
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
events {
worker_connections 10240;
}
http {
include mime.types;
default_type application/octet-stream;
server_names_hash_bucket_size 128;
client_header_buffer_size 32k;
large_client_header_buffers 4 32k;
client_max_body_size 8m;
sendfile on;
tcp_nopush on;
tcp_nodelay on;
upstream 192.168.2.62 {
server 192.168.2.62:8081;
server 192.168.2.62:8082;
}
server {
listen 80;
server_name 192.168.2.62;
location / {
proxy_pass http://192.168.2.62;
proxy_set_header X-Real-IP $remote_addr;
}
}
}
设置Nginx自动启动，启动脚本如下：
#!/bin/bash
# nginx Startup script for the Nginx HTTP Server
# chkconfig: - 85 15

# It has a lot of features, but it‘s not for everyone.

RETVAL=0
prog="nginx"
# Start nginx daemons functions.
start() {
if [ -e /usr/local/nginx/logs/nginx.pid ];then
echo "nginx already running...."
exit 1
fi
echo -n "Starting $prog: "
$nginxd -c ${nginx_config}
RETVAL=$?
echo
[ $RETVAL = 0 ] && touch /var/lock/subsys/nginx
echo -n "nginx starting done"
return $RETVAL
}
# Stop nginx daemons functions.
stop() {
if [ ! -e /usr/local/nginx/logs/nginx.pid ];then
echo "nginx not running...."
exit 1
fi
echo -n "Stopping $prog: "
$nginxd -s quit
sleep 2s
RETVAL=$?
echo
[ $RETVAL = 0 ] && rm -f /var/lock/subsys/nginx /usr/local/nginx/logs/nginx.pid
}
# See how we were called.
case "$1" in
start)

echo $"Usage: $prog {start|stop|restart}"
exit 1
esac
