在RedHat 9中如何设定一个用户能够打开的最大文件数？？？

{不知道哪里有sysctl的新的文档。
旧的好像不能用。比如
sysctl -w net.inet.tcp.log_in_vain=1
sysctl -w net.inet.udp.log_in_vain=1
这两个命令不知道用什么代替了}

姐姐.=号中间有空格的

事实证明，没有空格是对的

[root@linux shessical]# sysctl -w net.inet.udp.log_in_vain =1
error: 'net.inet.udp.log_in_vain' must be of the form name=value
error: Malformed setting '=1'
[root@linux shessical]# sysctl -w net.inet.udp.log_in_vain=1
error: 'net.inet.udp.log_in_vain' is an unknown key

复制代码

查google,基本上都是bsd的，很少linux的。有也是编程的。

在RedHat 9中如何设定一个用户能够打开的最大文件数？？？

这两个是做什么用的？

其它的都不懂是什么意思。

原帖由 "wangfeixue" 发表：
sysctl -a |more
sysctl -w file-max = 20000000000000你想添多少添多少!

你这样只是修改了整个系统可以同时打开的文件数，并没有针对单个用户，也就是说只有root用户可以享受到这样的好处。
我的目的是想非root用户直接用 ulimit -n 200000 这样的命令修改自己可以同时打开的文件数。

在RedHat 9中如何设定一个用户能够打开的最大文件数？？？

找到答案了
在/etc/pam.d/login 里面添加一句
session required pam_limits.so

然后
修改 /proc/sys/fs/file-max 的值为所有用户能够打开的文件数，（e.g. 在/etc/sysctl.conf文件中加入一行 fs.file-max = 200000 ，然后在命令行中输入：sysctl –p ，使其生效）。

编辑 /etc/security/limits.conf: 文件，插入一行：userx hard nofile 16000

用userx身份登录，在命令行中敲入 ulimit -n 16000

为了让设置永久生效，编辑用户的登陆环境文件 /home/userx/.bashrc ，插入一行：ulimit -n 16000
