Ulimit change story

The alarm always starts in the early morning and crawls to query logs. When the server is restarted, the following error occurs: Bash: fork: retry: the resource is temporarily unavailable.

Run the following command after the service is started successfully:

Ulimit-A: 1024

The result is modified.

Ulimit-N 655356 # maximum files that can be opened ulimit-u 65536 # maximum number of processes that can be created

To make the next restart take effect

Modify:

/Etc/security/limits. conf

Add the following content at the end of the limits. conf configuration file:

* soft nofile 655360* hard nofile 655360* soft noproc 65536* hard noproc 65536

However, we found that the system limit has not been changed to the value I modified. The query result is that centos 6 has introduced

The/etc/security/limits. d/90-nproc.conf configuration file limits the maximum number of systems.

Modify/etc/security/limits. d/90-nproc.conf to solve the problem!
