Keepalived notify script isn't executed
I had this same issue too, my notify script wasn't being executed, at the end of the day, I realized SELinux was blocking my script from being run, I found this out by typing:
[root@server ~]# journalctl
so go through the output, it will give you a hint as to the command to disable SELinux so your notify script can run. Also, I didn't use notify but
notify_master "/path/to/script"
notify_backup "/path/to/script"
Result from SELinux: If you believe that keepalived should have the dac_override capability by default. Then you should report this as a bug. You can generate a local policy module to allow this access. Do allow this access for now by executing these commands:
ausearch -c 'keepalived' --raw | audit2allow -M my-keepalived
semodule -i my-keepalived.pp
Once you run these commands, restart keepalived:
service keepalived restart

I just set up the notification script in
/etc/keepalived/keepalived.conf
/etc/keepalived/keepalived.conf
global_defs { notification_email { [email protected] } notification_email_from [email protected] smtp_server 127.0.0.1 smtp_connect_timeout 30 router_id DEFAULT_ROUT_ID } vrrp_script notification { script "" interval weight } vrrp_instance VI_1 { interface eth0 virtual_router_id 10 nopreempt state backup priority 110 advert_int 1 virtual_ipaddress { 22.22.22.22 } track_script { notification } notify_master "/etc/keepalived/master.sh" notify_backup "/etc/keepalived/backup.sh" }
And Whenever the state changes, it comes out
It seems working but those shellscripts are not executed.
Do you have any suggestion?

svrist over 8 yearsI've actually seen the same. I moved the lines to another location in the instance definition and then they worked....
