As normaluser
:
$ ulimit -n 4096
-bash: ulimit: open files: cannot modify limit: Operation not permitted
As root it works as desired - but then it won't affect normaluser
.
How to get out of this catch 22? I'll need this to be persistent.
回答1:
You may want to look at /etc/security/limits.conf
回答2:
To change file descriptor limit as normal user before running any applicaiton.
I use this small utility fdlimit which will increase file descriptor limit using "setrlimit()" system call before executing any program.
I use it like this
$ sudo ./fdlimit <fdlimit> <program_to_run>
