临时设置

ulimit -HSn 65536
ulimit -HSm 65536
		

echo "ulimit -SHn 65530" >> /root/.bash_profile
echo "ulimit -SHm 16000000" >> /root/.bash_profile
echo "ulimit -HSn 65536" >>/root/.bash_profile
		

使用“*”作用于所有用户，但见这样设置，最好的方式是针对需要的用户个别设置

* hard nofile 65536
" >>/etc/security/limits.conf > /dev/null 2>&1
