Linux: Open Files Limit

"Too many open files (24)"

Pernah kene? Dah ko scan x beragak..hahaha. Tue sebab ko dah cecah limit. Run cmd as root, Jom cek brape limit korang dengan cmd:

cat /proc/sys/fs/file-max

Default aku: 209708

Check Hard Limit:

ulimit -Hn

Default aku: 1048576

Check Soft Limit:

ulimit -Sn

  

Default aku: 1024

Per-User Limit:

cat /etc/security/limits.conf

Jom aku ajar cara nak ubah, bg besar skit!



1. edit /etc/security/limits.conf, aku letak 500k mcm dibawah:

* hard nofile 500000
* soft nofile 500000
root hard nofile 500000
root soft nofile 500000

2. Edit sysctl.conf fail yg aku post sebelum nie, sblum tue ko cek dulu:

cat /proc/sys/fs/file-max

cat /etc/sysctl.conf | grep fs.file-max

ubah: fs.file-max=500000

Cun! Jgn lupe run sysctl -p utk reload bila korang dah usik sysctl.conf nie.

Last step,

3. Edit fail nie: /etc/pam.d/common-session

Tambah line nie: session required pam_limits.so seperti dibawah:

Reboot and enjoy~!
