Modify the maximum number of files and processes that Linux users can open (Fork:retry:Resource temporarily unavailable)

today, whenJenkins released the app, it encountered an error, as follows:

/etc/profile:fork:retry:resource temporarily unavailable

Google , most people on the internet say that the reason may be that the number of user processes or the number of open files, reached the limit. According to this idea, I went to check the problem, found that the number of users of the process is More than the number of files opened to more than 1300

and through Ulimit–a , see

Openfiles (-N) 1024

Maxuser processes (-u) 1024

Haha, find it, solve it

Method One:

Modify /etc/security/limits.confdirectlyand add the following ( because the user you want to modify is Hades) :

@hades Soft Nofile 65535

@hades Hard Nofile 65535

@hades Soft Nproc 65535

@hades Hard Nproc 65535

Many people on the web said that the need to restart, then I was frightened, the production server can not restart.

In fact, do not need to restart the server , after a few minutes, the server will reread the file, you just re-login to a shell, you know,OK , hey, do not thank me here, I also after the expert guidance to know, the specific reason I would like to re-see Brother Bird.

Method Two:

in the current user's ./bash_profile , add a row

Ulimit–n 65535 , each time you enter the user's Shell , but I think it's a good method. Low , do you think?

Well, it's over here, and next time, o (∩_∩) o
