First, I understand the CentOS 8 linux distro is 'not supported' to run with 10.6.1 yet some of us push the envelope... and I'm hoping this isn't related to CentOS 8...
I cannot get ArcGIS Server to start with the OS and I've followed these steps:
To configure ArcGIS Server to start with the operating system follow these steps:
Within a command shell, switch to root user.
Copy <ArcGIS Server installation directory>/framework/etc/scripts/arcgisserver.service unit file to /etc/systemd/system using the command:
$ cp <ArcGIS Server installation directory>/framework/etc/scripts/arcgisserver.service /etc/systemd/system
Run the following command as root user to automatically create the links in /etc/systemd/system/multi-user.target.wants:
$ systemctl enable arcgisserver.service
To verify that the systemd service is properly configured, restart the service and check its status.
$ systemctl stop arcgisserver.service
$ systemctl start arcgisserver.service
$ systemctl status arcgisserver.service
It fails during the $ systemctl start arcgisserver.service command. See below:
[root@agsvr ~]# systemctl start arcgisserver.service
Job for arcgisserver.service failed because the control process exited with error code.
See "systemctl status arcgisserver.service" and "journalctl -xe" for details.
[root@agsvr ~]# systemctl status arcgisserver.service
