测并发 Too many open files 问题的解决

ulimit -a 查看限制显示:

core file size          (blocks, -c) 0
data seg size           (kbytes, -d) unlimited
scheduling priority             (-e) 0
file size               (blocks, -f) unlimited
pending signals                 (-i) 23256
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) 23256
virtual memory          (kbytes, -v) unlimited
file locks                      (-x) unlimited

ulimit -n 65535将 open files的限制改大

这里只是改变当前shell的限制

全局改变把ulimit -n 65535加到/etc/profile

或者将这个语句加到启动指定程序的shell脚本
