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？
" Y6 j6 P4 O5 i" {! n' y! ~#track_script{

$ B8 U' t& q! Y- Y

#     check_run

#  }

这是部分参数：

vrrp_instance V_1 {
    state MASTER
0 O( {5 _% p0 X- k8 [    interface eno16780032

使用ip addr 时发现
* x5 S0 a) B7 `6 a4 Jip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。
