keepalived无法调用track_script里的脚本，绑定VIP失败

[littleboybin]

配置文件内容
[root@localhost ~]# more /etc/keepalived/keepalived.conf
! Configuration File for keepalived
! extra script call demonstration
! scripts are supported in Instance and groups
! declarations.
global_defs {
router_id localhost
}
vrrp_script check_run{
script "/opt/test.sh"
interval 5
}
vrrp_sync_group G1 {
group {
VI_1
}
}

vrrp_instance VI_1 {
state MASTER
interface eth0
virtual_router_id 51
priority 90
advert_int 1
authentication {
auth_type PASS
auth_pass admin123
}
track_script{
check_run
}
virtual_ipaddress {
192.168.0.115
}
}

脚本很简单
[root@localhost opt]# ./test.sh
hello

查看日志，无法绑定VIP

但是如果将keepalived.conf 中的
track_script{
check_run
}
这三行注释掉，又能绑定VIP。查看日志如下：

无论换了哪个版本，都是一样。脚本也chmod 777了。iptables和selinux都已经关闭。求哪位大神帮忙解决下。

[牛迁迁]

把 ，track_script {} 放到 virtual_ipaddress{}的下面。

[u010242127]

我看到你主备的优先级都是90，把备的改低

[sswvf520]

我遇到你和一样的问题。权限也给了777都不得行。。最后发现是个很吐血的原因 track_script{ t和{需要加一个空格。不能连在一起

[cqyy725]

我不知道你用的什么版本的。虚拟ip配了，你的真实ip呢？ 我贴一段我的吧 两台机器，196是虚拟，211 和201是物理机 global_defs { router_id LVS_DEVEL } vrrp_instance VI_1 { state MASTER interface ens32 virtual_router_id 51 priority 100 advert_int 1 authentication { auth_type PASS auth_pass 1111 } virtual_ipaddress { 192.100.1.196 } } virtual_server 192.100.1.196 8080 { delay_loop 6 lb_algo rr lb_kind DR nat_mask 255.255.255.0 persistence_timeout 50 protocol TCP real_server 192.100.1.211 8080 { weight 1 TCP_CHECK{ connect_timeout 3 nb_get_retry 3 delay_before_retry 3 connect_port 8080 } } } }

[jiaxiangwo]

确实是因为 track_script{ t和{需要加一个空格

[-Cristiano-]

还真是，加个空格就好了，太变态了
