然后在2台broker上配置vip，用keepalived来控制vip 这个能详细点吗

vip是什么啊？

说习惯了，virtual ip,也就是第2个ip
通过ip addr 看出来是这样的

5: br-lan: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP qlen 1000
    link/ether 8c:21:0a:d9:e5:11 brd ff:ff:ff:ff:ff:ff
    inet 192.168.1.204/24 brd 192.168.1.255 scope global br-lan
       valid_lft forever preferred_lft forever
    inet 192.168.1.205/24 scope global secondary br-lan
       valid_lft forever preferred_lft forever

复制代码

这是keepalived的简单配置（在linux服务器上）

在第一台openwrt上是这样的：

config global_defs
config ipaddress
        option name     "ipaddress2"
        option address  "192.168.1.205/24"
        option device   "br-lan"
config vrrp_instance
        option name                     "VI_1"
        option state                    "MASTER"
        option interface                "br-lan"
        option auth_type                "PASS"
        option auth_pass                "passwordxxx"
        list virtual_ipaddress          "ipaddress2"
        option virtual_router_id        "128"
        option priority                 "128"
        option advert_int               "5"

复制代码

在第2台openwrt上是这样配置的：/etc/config/keepalived

config global_defs
config ipaddress
        option name     "ipaddress2"
        option address  "192.168.1.205/24"
        option device   "br-lan"
config vrrp_instance
        option name                     "VI_1"
        option state                    "BACKUP"
        option interface                "br-lan"
        option auth_type                "PASS"
        option auth_pass                "passwordxxxx"
        list virtual_ipaddress          "ipaddress2"
        option virtual_router_id        "128"
        option priority                 "128"
        option advert_int               "5"

复制代码

然后再enable keepalived为开机程序
/etc/init.d/keepalived enable
/etc/init.d/mosquitto enable

原来op也支持vrrp啊
