一、系统环境： 系统版本：CentOS5.5 x86_64 master_ip:172.20.27.40 backup_ip:172.20.27.50 vip:172.20.27.200 web_1: 172.20.27.90 web_2:172.20.27.100 二、haproxy安装： 1.首先172.20.27.40安装上安装： 1.1安装 tar zxvf haproxy-1.3.20.tar.gz cd haproxy-1.3.20 make TARGET=linux26 PREFIX=/usr/local/haproxy make install PREFIX=/usr/local/haproxy 1.2.配置 cd /usr/local/haproxy mkdir etc cd etc vi haproxy.cfg
global log 127.0.0.1 local0 maxconn 65535 chroot /usr/local/haproxy uid 99 gid 99 daemon nbproc 12 pidfile /usr/local/haproxy/haproxy.pid defaults log 127.0.0.1 local3 mode http option httplog option httpclose option dontlognull option forwardfor option redispatch retries 2 maxconn 65535 balance source stats uri /web-status stats auth admin:admin@admin stats refresh 60s contimeout 5000 clitimeout 50000 srvtimeout 50000 listen 172.20.27.200 bind *:80 mode http option httplog log global option httpchk HEAD /t.htm HTTP/1.0 server web1 172.20.27.90:80 weight 5 check inter 2000 rise 2 fall 3 server web2 172.20.27.100:80 weight 5 check inter 2000 rise 2 fall 3 然后启动haproxy，如下执行启动命令： /usr/local/haproxy/sbin/haproxy -f /usr/local/haproxy/etc/haproxy.cfg 2.首先172.20.27.50安装上安装： 2.1.安装 tar zxvf haproxy-1.3.20.tar.gz cd haproxy-1.3.20 make TARGET=linux26 PREFIX=/usr/local/haproxy make install PREFIX=/usr/local/haproxy 2.2.配置 cd /usr/local/haproxy mkdir etc cd etc vi haproxy.cfg
