# 错误异常too many open files解决方法  #

用命令ulimit -a查看

\[root@localhost webapps\]\# ulimit -a  
core file size          (blocks, -c) 0  
data seg size           (kbytes, -d) unlimited  
scheduling priority             (-e) 0  
file size               (blocks, -f) unlimited  
pending signals                 (-i) 31190  
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) 31190  
virtual memory          (kbytes, -v) unlimited  
file locks                      (-x) unlimited  
通过以上命令，我们可以看到open files 的最大数为1024

对于并发量比较大的网站这个限制是有些捉襟见肘的，所以我通过这个命令

ulimit -n 10240但是ulimit -n 10240 命令只能临时的改变open files 的值，当

重新登陆后又会恢复，所以需要永久设置open files 的值，

修改/etc/security/limits.conf 添加如下一行：

\* - nofile 10240
