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{
1 n& g. F3 V& |

#     check_run

#  }

9 s4 k' z* q, [- @, l. O

9 E! G. O6 A& z0 K. m9 c% ], k

这是部分参数：

vrrp_instance V_1 {
5 n% q7 _' \2 P9 o4 o" p    state MASTER
+ \7 ~9 u' p. G+ ?: l  k- H9 w% H    interface eno16780032

使用ip addr 时发现
& L' v; Y2 i9 P; hip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。
