测试keepalived服务时，发现虚IP地址不能被启动

admin

检查了配置文件，发现没有什么问题，但是注释掉这个地方之后，发现能启动虚IP地址，为什么？
#track_script{

% P; z- V5 U6 x' i: g) E" S* L6 W6 \. ~$ _

#     check_run

#  }

这是部分参数：

vrrp_instance V_1 {
    state MASTER
    interface eno16780032
) D7 i" I; E  C    virtual_router_id 5
3 E8 q0 X4 M' M0 e    priority 10
advert_int 1
#track_script{
#     check_run
; v" p6 {+ {9 q, ?" e/ @ #  }
& G4 o3 k& m! J! s    authentication {
        auth_type PASS
        auth_pass 112
    }
    virtual_ipaddress {
        192.168.7.17/24 dev eno16780032
    }

; `( ^' s$ |( M

使用ip addr 时发现
' i  ]1 g6 l; C, j) Zip地址已经写入：
inet 192.168.7.17/24 brd 192.168.7.255 scope global eno16780032
可以尝试一下这些参数。

还要注意selinux也会影响keepalived启动虚拟ip地址。
