33.3.3　配置HAProxy高可用性

本节主要是在binghe155服务器和binghe156服务器上通过配置Keepalived达到HAProxy的高可用。

1．配置Keepalived

分别在两台服务器上编辑/etc/keepalived/keepalived.conf文件，修改后的文件分别如下：

binghe155服务器：

! Configuration File for keepalived
global_defs {
    router_id binghe155
}
vrrp_script chk_haproxy {
    script "/usr/local/keepalived/haproxy_check.sh"
    interval 2
    weight 2
}
vrrp_instance VI_1 {
    state BACKUP
    interface eth0
    virtual_router_id 100
    priority 120
    nopreempt
    advert_int 1
    authentication {
        auth_type PASS
        auth_pass 1111
    }
    track_script {
        chk_haproxy
    }
    virtual_ipaddress {
        192.168.175.100
    }
}
virtual_server 192.168.175.100 48800 {
    delay_loop 2
    nat_mask 255.255.255.0
    persistence_timeout 50
