  #查看目前资源限制的设定  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) 7268  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) 7268  virtual memory   (kbytes, -v) unlimited  file locks      (-x) unlimited    #查看系统打开文件的最大限制数  ulimit -n  1024
