修改RemoveIPC参数
为了避免linux7.2的新特性，在一个user完全退出OS后会remove掉所有的IPC对象，需要修改如下参数
1).设置/etc/systemd/logind.conf中RemoveIPC=no 2).重启服务器或者重启systemd-logind 重启systemd-logind： # systemctl daemon-reload
# systemctl restart systemd-logind
配置文件系统描述符

检查用户限制
check resource limits:
1. Log in as an installation owner.
2. Check the soft and hard limits for the file descriptor setting. Ensure that the result is in the recommended range, for example: $ ulimit -Sn 1024
$ ulimit -Hn 65536
3. Check the soft and hard limits for the number of processes available to a user. Ensure that the result is in the recommended range, for example: $ ulimit -Su 2047
$ ulimit -Hu 16384
4. Check the soft limit for the stack setting. Ensure that the result is in the recommended range, for example: $ ulimit -Ss 10240
$ ulimit -Hs 32768
