我已更改/etc/security/limits.com并远程重新启动计算机,但启动后nproc参数仍为旧值。重新启动后ulimit chnage无效

[[email protected] ~]$ cat /etc/security/limits.conf

* - nofile  4096

请看到我设置max user processes 4096,但在重新启动后,该值仍是1024

请看看一个名为/etc/pam.d/sshd文件。 如果您可以找到它,请打开该文件并插入以下行。

session required pam_limits.so 

然后即使重新启动后新值也会生效。

PAM是一个与认证有关的模块。所以你需要通过ssh登录启用模块。

有关man pam_limits的更多详细信息。

谢谢!

这会影响计算节点或服务器吗?我的意思是我应该在服务器上还是在每个计算节点上编辑该文件? – mahmood

嗨mahmood,这是一个服务器上的设置。你不必在每个节点上都这么做。 – ntakashi
