Haproxy與keepalived高可用搭建

1）配置網路，安裝軟體

yum -y install haproxy

vim /etc/haproxy/haproxy.cfgglobal log

…listen websrv-rewrite 0.0.0.0:80

balance roundrobin

server web1 192.168.2.100:80 check inter 2000 rise 2 fall 5

server web2 192.168.2.200:80 check inter 2000 rise 2 fall 5

…定義web伺服器可多台…

systemctl start haproxy

systemctl enable haproxy

注意：兩台haproxy伺服器做相同的操作

web1 ~]# yum install -y keepalived

web2 ~]# yum install -y keepalived

vim /etc/keepalived/keepalived.conf

systemctl無法停掉keepalived

這個問題搞了好半天，記錄一下，啟停都是用的systemctl 起初是測試vip漂移時候發現，主備節點都開啟keepalived的狀況下，一切正常，主節點的vip也可以訪問。第一次停掉主節點的keepalived程式時，vip順利漂移到從節點 再次啟動主節點keepalived，vip順利漂移到主節點...
