Openfire process does not follow ulimit nofiles value in limits.conf

I have the following values set in my

/etc/security/limits.conf

*          hard    nofile   1048576
*          soft    nofile   1048576
openfire   hard    nofile   1048576
openfire   soft    nofile   1048576

I expect the openfire process to set its value to the same. But when I do a cat of openfire's PID. It only shows the value of 'Max open files' to be 4096.

cat /proc/178747/limits

Max realtime timeout      unlimited            unlimited            us

How can I configure my machine (Centos 7) so that the Openfire process follows the value set in the limits.conf

CentOS7 uses systemd which sets its' own limits.

Adding LimitNOFILE=65536 in the [Service] section of /etc/systemd/system/openfire.service and then restarting the service should do the trick.

Background: Systemd ignores the configuration in limits.conf.

  1. There is a default for the max. number of open files which is 4096 on older systems and 64k on newer systems. All "units" not explicitly changing the limits will inherit this.

  2. This default can be overwritten in /etc/systemd/system.conf, option "DefaultLimitNOFILE="

  3. Per "unit" it can be configured in the unit definition file (see above)

/etc/security/limits.conf change is handy when system restarts, for current state, you should do "ulimit -n 1048576" on terminal and then restart openfire service and verify. This will apply immediately.
