centos keeplive ipv6配置

一、启用keeplive

systemctl enable keepalived

二、检查keeplive

systemctl status keepalived

三、修改配置文件/etc/keepalived/keepalived.conf

1.   node2(backup node)

! Configuration File for keepalived
global_defs {
    #router_id LVS_DEVEL_IPv6  # 路由标识，建议唯一:cite[6]
    # 可配置全局的IPv6组播地址（一般使用默认值即可）:cite[3]
    # vrrp_mcast_group6 ff02::12
}
