Raising hard limit on RLIMIT_NOFILE system-wide on Linux
- by jonswar
We need to raise RLIMIT_NOFILE when running memcached, as we're hitting the default hard limit (1024). However, raising a hard limit requires root, and for various reasons we don't want to have to run memcached or its containing shell as root. Right now we happily run it as a non-root user.
Is there a way to raise the hard limit for RLIMIT_NOFILE system-wide, so that we can continue to run memcached as non-root and simply raise the soft limit?
This is RedHat Linux with 2.6 kernel.
Thanks!
