Ubuntu 16 – how to increase maximum file open limit ( ulimit -n )

If you are setting up nginx,chances are you will discover your worker_connections is at some low number, such as 1024. You can’t increase this number unless you increase kernel limit as well. First of all run cat /proc/sys/fs/file-max to discover your maximum limit.

abc@ubuntu:~$ cat /proc/sys/fs/file-max
1048576
abc@ubuntu:~$ ulimit -n
1024
