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{

/ j# [! ^. S0 ]: a

#     check_run

5 g( I3 ~' c, {% o' p5 H/ [

#  }

9 P# H6 S0 B' ?+ e

这是部分参数：

vrrp_instance V_1 {
& H. y) m0 G8 ]5 k    state MASTER
& u4 Y  g; G: q3 |3 q# O    interface eno16780032
    virtual_router_id 5

使用ip addr 时发现
ip地址已经写入：
8 w6 E/ ~1 W! Rinet 192.168.7.17/24 brd 192.168.7.255 scope global eno16780032
) x8 ]/ F5 N9 k/ u* D% Q% m( W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。
