Nginx Load Balancer Cluster

Nginx load balancing function In fact and Nginx proxy is the same function, just to the previous agent a machine to agent more than one machine, nginx load and compared to LVS, Nginx belongs to a more advanced application layer, not involved in IP and kernel changes, It simply forwards the user's request to the back of the machine, so the backend real server does not need to configure the public IP

First, configure the environment

Nginx Dispatcher (a public network 192.168.101.230 and an intranet IP192.168.104.230)

Rs1 Intranet IP (192.168.104.108)

RS2 Intranet IP (192.168.101.109)

Second, the specific configuration process

[Email protected] ~]# cd/usr/local/nginx/conf/vhosts/

[[email protected] vhosts]# ls

default.conf proxy.conf test.conf

[Email protected] vhosts]# vim lb.conf

Upstream Daixuan {

Ip_hash;

Server 192.168.104.108:80;

Server 192.168.104.109:80;

}

server {

Listen 80;

server_name www.daixuanlinux.com;

Location/{

Proxy_pass http://Daixuan/;

Proxy_set_header Host $host;

}

}

[Email protected] vhosts]#/etc/init.d/nginx restart

Stop nginx: [OK]

Starting nginx: [OK]

[Email protected] vhosts]# ipvsadm-c

[Email protected] vhosts]# iptables-t nat-f

[Email protected] vhosts]# iptables-f

[Email protected] vhosts]# NETSTAT-LNP

Active Internet connections (only servers)

Proto recv-q send-q Local address Foreign address Stat e pid/program name

TCP 0 0 0.0.0.0:3306 0.0.0.0:* LIST EN 2492/mysqld

TCP 0 0 0.0.0.0:80 0.0.0.0:* LIST EN 2947/nginx

Third, testing

[Email protected] vhosts]# curl-xlocalhost:80 www.123.com

Turns out rs1rs1 and RS2R2 switch
