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。
我将以下行添加到 /etc/sysctl.conf
fs.file-max = 65536
并运行 sysctl -p
我将以下行添加到 /etc/security/limits.conf
* hard nofile 65536
没运气！重新启动后， ulimit -a 仍然给我：
core file size (blocks, -c) 0
data seg size (kbytes, -d) unlimited
scheduling priority (-e) 0

pending signals (-i) 26597
