在Linux中,ulimit命令用于限制用户对shell资源的访问,包括进程数、文件打开数等。这些限制可以分为软限制(soft limit)和硬限制(hard limit)。 软限制(soft limit)是当前系统生效的设置值,可以理解为一种警告的设定。当资源使用超过这个限制时,系统并不会立即阻止,而是会发出警告信息,提示用户已经接近或超过了限制。用...
软限制 (soft maxlogins):软限制是一个警告阈值,当达到或超过该限制时,系统会发出警告信息,但不会阻止用户登录。硬限制 (hard maxlogins):硬限制是一个严格的限制,当达到或超过该限制时,系统将阻止用户登录。 ┌──[root@liruilongs.github.io]-[~] └─$ulimit -Hn #限制数 262144 ┌──[root@liruil...

Check hard limit : Raw ulimit -a -H Check soft limit : Raw ulimit -a -S This solution applies to all limits set in the various limits files and with the ulimit command, not just nproc. It will refer to nproc specifically, but that's just for convenience sake, and because that seems...
set soft and hard limits to the same value, or soft:hard to set both limits individually (e.g. LimitAS=4G:16G). Use the string infinity to configure no limit on a specific resource. The multiplicative suffixes K (=1024), M (=1024*1024) and so on for G, T, P and E may be us...

然而，直接在终端命令行执行的ulimit设置仅限于当前会话，重启后会失效。配置资源限制的深度理解limits.conf文件详解在/etc/security/limits.conf中，使用格式 <domain> soft/hard <item> <value> 来设置资源限制。例如，限制所有用户（*）的进程数（noproc）可以这样配置：* soft/hard noproc 65535，软...
Soft vs Hard Limits As a user, you can actually adjust your ulimit settings. You may be wondering why even set a limit if a user can adjust it. This is where soft and hard limits come into play. So from the admin perspective, you may prefer your user to hover around a certain value...
The value of limit can be a number in the unit specified below with each resource, or the value unlimited. The string unlimited requests that the current limit, if any, be removed. The –H and –S flags specify whether the hard limit or the soft limit for the specified resource is set...
