Need understand “ulimit”'s nofile setting in host and container

阅读更多关于 Need understand “ulimit”'s nofile setting in host and container

问题 As I know if we need adjust "open files" nofile (soft and hard) in linux system, we need run command ulimit or set in related configuraiton file to get the setting permanently.

Update In my environment, current setting with dockers

AMD APU A10-5800K， Debian Wheezy，系统安装ATI闭源驱动 http://my.oschina.net/emptytimespace/blog/87464 AMD APU A10-5800K 集成显卡是： AMD Radeon HD 7660D，请不是此类显卡者小心跟随。我们此处重点讨论在新立得中安装AMD ATI 的闭源催化剂驱动，主要是考虑到源中的驱动可以实时更新。如果想使用最新的驱动并且能够接受将来变旧，可就可能需要继续手动安装，那么可以到官网下载最新驱动，这在本文最后再提到。【方法一：（个人推荐）】 1）因为是闭源的，首先需要开启nofree的软件源 2）新力得中搜索安装所有 fglrx*（之前似乎需要安装build-essential） 3）# aticonfig --initial （有的使用：aticonfig --initial -f ，意为force，本人认为能不强制就不强制） 4）# depmod -a 生成 modules.dep 和 map 文件，似乎和模块加载顺序有关。 depmod will output a dependency list suitable for the modprobe utility 5）# reboot 安装完成，很简单吧，之后可以重启多次，因为我的似乎换不同内核启动过几次
