I want to change open file limit for a Riak service in CentOS 7. The problem is that Riak still uses SysV init script.
According to docs i have to create /etc/systemd/system/riak.d/NAME.conf
and set the parameter there. Then reload systemd and the service.
# In /etc/systemd/system/riak.d/limits.conf
[Service]
LimitNOFILE=65536
But this has no effect:
$ systemctl show riak -p LimitNOFILE
LimitNOFILE=4096
What did I do wrong? Does this work for SysV init scripts?
