作者: Grey 原文地址: Github 语雀 博客园 Too many open files是Linux系统中常见的错误,从字面意思上看就是说程序打开的文件数过多,不过这里的files不单是文件的意思,也包括打开的通讯链接(比如socket),正在监听的端口等等,所以有时候也可以叫做句柄(handle),这个错误通常也可以叫做句柄数超出系统限制.引起的原因就是进程在某个时刻打开了超过系统限制的文件数量以及通讯链接数. 通过命令ulimit -a可以查看当前系统设置的最大句柄数是多少 core…

ulimit -n 对应 /etc/security/limits.conf 文件设置 问题: Can’t open so many files 对于linux运维的同学们,相信都遇到过这个问题. 在Linux下一切资源皆文件,普通文件是文件,磁盘打印机是文件,socket 当然也是文件.系统默认设置成1024,但是这个数字对于服务器特别是大并发的远远是不够的,所以,我们需要结合实际情况修改成一个更大更合理的值. 修改方法 临时解决方案: ulimit -SHn 65535 永久解决方案,注意,…

一.内核模块的概念 Linux模块(module)是一些可以作为独立程序来编译的函数和数据类型的集合.内核模块给我们带来的便利是模块本身并不被编译进内核文件,可在内核运行期间动态的安装或卸载.因为如果将模块编译进内核的话,一是生产的内核文件过大,二是如果要添加或删除某个组件要重新编译整个内核. Linux模块可以通过静态或动态地加载到内核空间,静态加载是指在内核启动过程中加载:动态加载是指在内核运行的过程中随时加载.我采用的是动态加载的方法. 一个模块被加载到内核中时,它就成为内核代码的一部分,…
