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？
* _3 A; V4 J) p#track_script{

这是部分参数：

vrrp_instance V_1 {
; V9 N. S2 }; V    state MASTER
    interface eno16780032
$ Z, y% I. R1 d* ^# x3 O5 O6 a% v# `& @, b    virtual_router_id 5
    priority 10

    authentication {

    }
    virtual_ipaddress {

使用ip addr 时发现
ip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。
