Soft nofile. As long as you keep the soft limit at the default (1024), it's probably fairly safe to increase the hard limit. conf file. I don't know the technical difference between hard and soft and have always done both. It seems like adding: * soft nofile 65535 * hard nofile 65535 Is enough when editing the limit for non-root users. $ sysctl -p Login to that specific OS user and check: Check Hard and Soft values $ ulimit -a [oracle@<server> ~]$ ulimit -Hs 32768 [oracle@<server> ~]$ ulimit -Ss 32768 Modifying the OS What if I want to set the limits for a user that doesn't have a login, like if I want to set the nofile limit to 94000 for the mongodb user? How'd I do that without a reboot? What does "hard/soft nproc"mean on CentOS7 What diffrent with 'hard/soft nproc' or 'hard/soft noproc' THS /etc/security/limits. On my system, I see this: Changes made by ulimit 本文深入解析了Linux系统中soft和hard限制的区别，以及nproc和nofile的具体含义。soft代表警告设定，允许暂时超出但会警告；hard为严格限制，禁止超出。nproc控制用户最大进程 These terms have nothing to do with "soft" or "hard links" (file system pointers) and everything to do with **file descriptor limits**—a critical aspect of Linux resource management. In this What is the difference between "soft nofile" and "hard nofile" by configuring 'open file'? For example as below: Code: user1 soft 0 prlimit --nofile= softlimit: hardlimit did the trick for me. I know 本文介绍了Linux系统中`soft`和`hard`参数的区别，`soft`代表警告设定，允许超过但会有警告，而`hard`则表示严格限制，不允许超出。 以`nproc`和`nofile`为例，`nproc`限制每个用户可创建 Yes, the nofile can be larger than 65536. conf - * soft nofile 4096 * hard nofile 16384 However, wildcard * won't apply for root user. $ echo "ulimit -SHn 8192 # nofile" >>/etc/sysconfig/httpd $ service httpd restart 出现Socket/File: Can’t open so many files问题，任何*nux系统，限制数都可以由ulimit或setrlimit来设置。 Linux系统中与文件描述符相关的参数： soft/hard nofile 即ulimit -n查看到的值，” Let’s look at an illustration of a possible configuration: * hard nofile 4096 * soft nofile 1024 These lines set a hard limit of 4096 blocks and a soft limit Is it possible to change the soft - and hard limit of a specific process? In my case, my process is mongod and a lot of web resources tell me to simply execute: ulimit -n <my new value> Linux资源限制配置文件limits. itq z8b hw3m iizi us1
