nginx反向代理:192.168.1.1、192.168.1.2
web服务器 :192.168.1.3、192.168.1.4
这里的nginx是编译安装的,安装在/usr/loacl/下
正常启动nginx服务后进入配置文件(1.1和1.2都要配置)
#vim /usr/local/nginx/conf/nginx.conf
在http模块里添加:
upstream myCluster {
server 192.168.1.3:80;
server 192.168.1.4:80;
}
在server模块里面修改并添加:
修改: #location / {
#root html;
#index index.html index.htm;
#}
添加: location / {
proxy_pass http://myCluster;
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-for $proxy_add_x_forwarded_for;
}
#killall -s QUIT nginx
#nginx
创建简单的nginx启动脚本
#!/bin/bash
# chkconfig: - 99 20
# description: this is nginx server
PROG="/usr/local/nginx/sbin/nginx"
PIDF="/usr/local/nginx/logs/nginx.pid"
case "$1" in
start)
$PROG

kill -s QUIT $(cat $PIDF)
;;
restart)
$0 stop
$0 start
;;
reload)
kill -s HUP $(cat $PIDF)
;;
*)
echo "Usage: $0 {start|stop|restart|reload}"
exit 1
;;
esac
exit 0
安装keepalive(1.1和1.2上)
#tar -xzvf keepalived-1.2.13.tar.gz -C /usr/src/
#cd /usr/src/keepalived-1.2.13/
#yum install kernel-devel openssl-devel -y
#./configure --prefix=/ --with-kernel-dir=/usr/src/kernels/2.6.32-431.el6.x86_64/
#make && make install
#chkconfig --add keepalived
#chkconfig keepalived on
#cp /etc/keepalived/keepalived.conf /etc/keepalived/keepalived.conf.bak
#vim /etc/keepalived/keepalived.conf
