Increasing the number of open file descriptors – LINUX

Increasing the number of open file descriptors – LINUX, take 131072 as example.

1, increase this to 131072 for all users

vi /etc/security/limits.conf

* soft nofile 131072

* hard nofile 131072

2, ulimit –n 131072

3, You may have to modify ssh and login in pam.d. Because if not, you open a session using ssh, it will not take effect.

vi /etc/pam.d/sshd

Add

session required /lib/security/pam_limits.so

vi /etc/pam.d/login

Add

session required /lib/security/pam_limits.so

4, service sshd restart
