CentOS 6.5 使用HaProxy實現Load Balance

目前機器跟參考資料的機器一樣，只是換個系統而已
web1以及web2輸入以下指令安裝Apache

yum install -y httpd

LB的Server則輸入以下指令安裝HaProxy

yum install -y haproxy

web1以及web2安裝好時輸入以下指令並讓Apache服務再開機時自動執行

hostname > /var/www/html/index.html
chkconfig httpd on
service httpd start

LB5這邊輸入以下指令編輯配置檔，配置檔如下

vi /etc/haproxy/haproxy.cfg


global
    log         127.0.0.1 local2

    chroot      /var/lib/haproxy
    pidfile     /var/run/haproxy.pid
    maxconn     4000
    user        haproxy
    group       haproxy
    daemon

    timeout http-keep-alive 10s
    timeout check           10s
    maxconn                 3000

        stats refresh 30s
        balance roundrobin
        option httpclose
        option forwardfor
        server web1 WEB1 IP:80 weight 1 check
        server web2 WEB2 IP:80 weight 1 check

目前透過瀏覽器可以看到Web1和Web2的畫面切換
