在ubuntu上运行service服务报错：
Failed to allocate directory watch: Too many open files
解决方法如下：

echo 'fs.inotify.max_user_instances=512' >> /etc/sysctl.conf
echo 'fs.inotify.max_user_watches=262144'  >> /etc/sysctl.conf

sysctl -p

echo '*               -       nofile          65535 ' >>/etc/security/limits.conf
tail -1 /etc/security/limits.conf
ulimit -SHn   65535
ulimit -n
