重新啓動後ulimit chnage無效

我已更改/etc/security/limits.com並遠程重新啓動計算機，但啓動後nproc參數仍爲舊值。重新啓動後ulimit chnage無效

[[email protected] ~]$ cat /etc/security/limits.conf 
* - memlock  -1 
* - stack  -1 
* - nofile  4096 
* - nproc  4096  <=====================================

請看到我設置max user processes 4096，但在重新啓動後，該值仍是1024

請看看一個名爲/etc/pam.d/sshd文件。如果您可以找到它，請打開該文件並插入以下行。

session required pam_limits.so

然後即使重新啓動後新值也會生效。

PAM是一個與認證有關的模塊。所以你需要通過ssh登錄啓用模塊。

有關man pam_limits的更多詳細信息。

謝謝！

這會影響計算節點或服務器嗎？我的意思是我應該在服務器上還是在每個計算節點上編輯該文件？ – mahmood

嗨mahmood，這是一個服務器上的設置。你不必在每個節點上都這麼做。 – ntakashi
