Unitech/pm2#2962

There're 2 PM2 daemons:

[root@VNPT-HCM-BIMAX-02 ha]# ps -ef | grep pm2 root 4832 1 0 23:36 ? 00:00:00 PM2 v2.6.1: God Daemon (/root/.pm2) root 5704 1 0 23:36 ? 00:00:01 PM2: KM Agent (/root/.pm2) root 6590 7738 0 23:41 pts/0 00:00:00 grep --color=auto pm2 root 22478 1 0 23:06 ? 00:00:06 PM2 v2.6.1: God Daemon (/etc/.pm2)

Turned out that supervisor uses PM2 Home as /etc/.pm2

[root@VNPT-HCM-BIMAX-02 ~]# export PM2_HOME=/etc/.pm2
[root@VNPT-HCM-BIMAX-02 ~]#
[root@VNPT-HCM-BIMAX-02 ~]#
[root@VNPT-HCM-BIMAX-02 ~]#
