Description
This is actually in version 1.1.1, but I don't see that as an option in the "Affects Version/s" drop-down.
Maybe it's due to its use of systemd, but MaxScale's init script doesn't work very well on CentOS 7. The output seems to be wrong or confusing much of the time.
"start" says it succeeds even if it fails:
[gmontee@localhost ~]$ sudo /etc/init.d/maxscale start
|
Starting maxscale (via systemctl): [ OK ]
|
[gmontee@localhost ~]$ ps -elf | grep "maxscale"
|
0 R gmontee 12149 10911 0 80 0 - 28160 - 16:32 pts/0 00:00:00 grep --color=auto maxscale
|
"status" output is kind of confusing. it seems to indicate that the process is running when it isn't, and also tries to start the process again if it isn't running:
[gmontee@localhost ~]$ sudo /etc/init.d/maxscale status
