#1: memory limit/quota per user

Posted on 2010-06-08 12:32:46 by Tharindu Rukshan Bamunuarachchi

Hello All,

Is it possible to limit memory quota per user (like disk quota) in linu=
x ?

AFAIK, RLIMIT_* (i.e. RSS, DATA) are applicable per process not per use=
r.

thankx a lot.
tharindu.

Unless something has changed recently, not with standard utilities.
Maybe SELinux or similar allows for something like that but otherwise
it's impossible.

You can use the pam security limits feature.

Simply check that the module is being loaded in pam.d:

/etc/pam.d/system-auth:session required pam_limits.so=20

Then use the /etc/security/limits.conf file:
<user> soft|hard memlock <value>

Memory limits are per-process, not per-user (and "memlock" controls
the amount of memory which can be mlock()d, which has little bearing
on memory usage overall).

The only per-user resource limit is the total number of processes.
