Increase the maximum number of file descriptor limit
- Thread starter IO
- Start date
If you start the server with root account, LSWS will do that for you. If you start the server with 'nobody', you need to change /etc/security/limits.conf .

Is this per client process or for the whole server? Is this simply number of files on all virtual servers or something else? What happens when descriptors are exceeded?
I have about 150,000 files on my main site to be served. I want to be clear about this before I make the server transfer and go live.
My problem is that server can not be set to run by root without reinstalling (don't want to do that because of resetting all configs, and it is a security risk), and RHEL 5 /etc/security/limits.conf does not have setting for file descriptors, or is it the " nofile - max number of open files" setting?
[root@main ~]# cat /proc/sys/fs/file-nr
1020 0 767711
Code:
[root@main ~]# cat /etc/security/limits.conf
# /etc/security/limits.conf
#
#Each line describes a limit for a user in the form:
#
#<domain> <type> <item> <value>
#
#Where:
#<domain> can be:
# - an user name
# - a group name, with @group syntax
# - the wildcard *, for default entry
# - the wildcard %, can be also used with %group syntax,
# for maxlogin limit
#
#<type> can have the two values:
# - "soft" for enforcing the soft limits
# - "hard" for enforcing hard limits
#
#<item> can be one of the following:
# - core - limits the core file size (KB)
# - data - max data size (KB)
# - fsize - maximum filesize (KB)
# - memlock - max locked-in-memory address space (KB)
# - nofile - max number of open files
# - rss - max resident set size (KB)
# - stack - max stack size (KB)
# - cpu - max CPU time (MIN)
# - nproc - max number of processes
# - as - address space limit
# - maxlogins - max number of logins for this user
# - maxsyslogins - max number of logins on the system
# - priority - the priority to run user process with
# - locks - max number of file locks the user can hold
# - sigpending - max number of pending signals
# - msgqueue - max memory used by POSIX message queues (bytes)
# - nice - max nice priority allowed to raise to
# - rtprio - max realtime priority
#
#<domain> <type> <item> <value>
#
#* soft core 0
#* hard rss 10000
#@student hard nproc 20
#@faculty soft nproc 20
#@faculty hard nproc 50
#ftp hard nproc 0
#@student - maxlogins 4
# End of file

You do not need to reinstall the server.
6000 should be enough since it is ont likely that 150,000 files get accessed at the same time.
LSWS automatically set the file descriptor limit to 3 * "Max Connections". Your "Server"->"Tuning"->"Max Connections" is 2000 now. If you want a higher limit you can either increase "Max Connections" or set the limit manully.
