Editing the file requires a server reboot, you can use a simpler way:
编辑文件需要重启服务器，您可以使用更简单的方法：
chuser nofiles=10000 malintha
disconnect from you console and reconnect again using the username malintha. Use ulimit -nand the output should now be 10000.
断开与控制台的连接，然后使用 username 重新连接malintha。使用ulimit -n，输出现在应该是10000.

The problem here is that you specify "hard" in
这里的问题是你在
malintha hard nproc 10000
马林莎硬 nproc 10000
hard is the "max" limit, and soft is the default. So you can leave it as hard and then use ulimit -u 1000and processes after that point, for that bash shell, will have the increased limit, or use soft, then it will be the default for all processes started by your user [remember to logout and re-login with each change].
hard 是“最大”限制，soft 是默认值。因此，您可以将其保留为硬，然后ulimit -u 1000在该点之后使用和处理，对于该 bash shell，将增加限制，或使用软，然后它将成为您的用户启动的所有进程的默认值 [记得注销并重新- 每次更改时登录]。
For those looking to try and figure out why they are limited to [for instance] 1024 max theads for a given user, also note that it reads the /etc/security/limits.conf file and other /etc/security/limits.d/* files.
对于那些想尝试弄清楚为什么给定用户限制为 [例如] 1024 个最大 theads 的人，还要注意它读取 /etc/security/limits.conf 文件和其他 /etc/security/limits.d /* 文件。
