linux - 更改 ec2 实例上的打开文件数

Question

我正在使用 32 位 Amazon Linux(Centos？)。根据博客 http://gnufreakz.wordpress.com/2009/08/12/increase-ulimit-in-centos/我尝试更改一些参数。

我在/etc/sysctl.conf 中添加了以下行

fs.file-max = 65536

然后运行 ​​sysctl -p

我在/etc/security/limits.conf 中添加了以下行

*   hard    nofile  65536

运气不好!重启后，ulimit -a 仍然给我:

core file size          (blocks, -c) 0
data seg size           (kbytes, -d) unlimited
scheduling priority             (-e) 0
