折腾:

【已解决】在线CentOS中Flask运行mongo出错:pymongo.errors.ServerSelectionTimeoutError: localhost:32018: [Errno 111] Connection refused

期间,需要在CentOS中,搞清楚当前的mongo的server:mongod的运行的情况,确保的确是正在,正常,运行的。

centos mongod check status

unix – Is mongodb running? – Stack Overflow

<code>[root@xxx-general-01 logs]# ps aux | grep mongod

</code>

怎么status中显示是:active exited啊

<code>[root@xx-general-01 logs]# /etc/init.d/mongod status
● mongod.service - SYSV: Mongo is a scalable, document-oriented database.
   Loaded: loaded (/etc/rc.d/init.d/mongod; bad; vendor preset: disabled)
   Active: active (exited) since Mon 2018-05-14 16:42:01 CST; 3 months 14 days ago
     Docs: man:systemd-sysv-generator(8)

May 14 16:42:01 xx-general-01 systemd[1]: Started SYSV: Mongo is a scalable, document-oriented database..
</code>

或:

<code>[root@xx-general-01 logs]# systemctl status mongod
● mongod.service - SYSV: Mongo is a scalable, document-oriented database.
   Loaded: loaded (/etc/rc.d/init.d/mongod; bad; vendor preset: disabled)
   Active: active (exited) since Mon 2018-05-14 16:42:01 CST; 3 months 14 days ago
     Docs: man:systemd-sysv-generator(8)

May 14 16:41:58 xx-general-01 systemd[1]: Starting SYSV: Mongo is a scalable, document-oriented database....
May 14 16:41:58 xx-general-01 runuser[1175]: pam_unix(runuser:session): session opened for user mongod by (uid=0)
May 14 16:42:01 x-general-01 mongod[1140]: Starting mongod: [  OK  ]
May 14 16:42:01 x-general-01 systemd[1]: Started SYSV: Mongo is a scalable, document-oriented database..
</code>

所以,是可以现在强制去停掉并重启mongod,但是还是要去搞清楚为何此处mongod为何active但是existed了。

【无需解决】mongod的状态中active但却existed是什么意思

【总结】

本身想要在CentOS中查看Mongo的server:mongod的运行情况,可以:

(1)ps看进程

<code>ps -edaf | grep mongo
</code>

(2)用系统服务看详细状态

<code>/etc/init.d/mongod status
</code>

等价于:

<code>systemctl status mongod
</code>

等价于:

  • MongoDB version < 2.6:

    • service mongodb status

  • MongoDB version >= 2.6

    • service mongod status
