折腾:

【已解决】阿里云ECS服务器中已有的MongoDB的用户名密码和端口

期间,需要去搞清楚,是否服务器中是否已经正在,正常的,运行了mongod的MongoDB的服务了。

去服务器中运行mongod之后:

需要查看和确认,是否的确已经运行了:

查看mongodb 是否已经运行

通过查看端口状态查看mongodb是否已经启动 – CSDN博客

然后最后找到了验证方式:

<code>[root@naturling-general-01 ~]# netstat -lanp | grep 27017

</code>

果然已经在运行了mongod了。

【总结】

方式1:

<code>netstat -lanp | grep 27017
</code>

方法2:

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

方法3:

<code>systemctl status mongod
</code>

等价于:

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