System-Wide Settings

To show the number of files opened on a system, run:

# cat /proc/sys/fs/file-nr
1536	0	793120

The fields are:

Current number of opened files
Number of free allocated file descriptors
Maximum number of file descriptors for the whole system

You may change this value by:

cat <new value> > /proc/sys/fs/file-nr
Edit /etc/sysctl.conf so that there is a line
fs.file-max = <new value>

Per-User Settings

ulimit -n

cat /etc/security/limits.conf
