在ec2实例上更改打开文件的编号

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/我试着改变一些参数。

我添加了以下行到/etc/sysctl.conf

fs.file-max = 65536 

和跑的sysctl -p

我添加了以下行/etc/security/limits.conf文件

* hard nofile 65536 

不幸运！重新启动后，仍然的ulimit -a给我：

core file size   (blocks, -c) 0 
data seg size   (kbytes, -d) unlimited 
scheduling priority    (-e) 0 
file size    (blocks, -f) unlimited 
pending signals     (-i) 26597 
max locked memory  (kbytes, -l) 64 
max memory size   (kbytes, -m) unlimited 
open files      (-n) 1024 
pipe size   (512 bytes, -p) 8 
POSIX message queues  (bytes, -q) 819200 
real-time priority    (-r) 0 
stack size    (kbytes, -s) 8192 
cpu time    (seconds, -t) unlimited 
max user processes    (-u) 1024 
virtual memory   (kbytes, -v) unlimited 
file locks      (-x) unlimited
