Configure the systemd journal to be persistent across reboots.

1. Configure the directory /var/log/journal on serverX.

   [root@serverX ~]# mkdir /var/log/journal
   [root@serverX ~]# chown root:systemd-journal /var/log/journal
   [root@serverX ~]# chmod 2755 /var/log/journal
   

2. Send the USR1 signal to the systemd-journald or reboot serverX.

   [root@serverX ~]# killall -USR1 systemd-journald

To verify the systemd journal is persistent, look for a new directory with the systemd journal log files that have been written to /var/log/journal. (The exact files which appear may vary on your system, but the directory should have similar contents to the following example.)

[root@serverX ~]# ls /var/log/journal/4513ad59a3b442ffa4b7ea88343fa55f
system.journal     user-1000.journal
