docker下载mongodb镜像并启动容器

<p>1、查找mongodb相关镜像</p>
<div class="cnblogs_code">
<pre>docker search mongo</pre>
</div>
<p><img src="https://img2023.cnblogs.com/blog/2661519/202306/2661519-20230629112058024-393101937.png"></p>
<p>找到相关的镜像进行拉取，如果不指定版本，默认下载最新的mongoDB。建议自己先查找需要那个版本后在进行拉取，因为mongoDB不同版本之间差距较大。</p>
<p>2、拉取镜像</p>
<p>这里拉取mongodb6.0</p>
<div class="cnblogs_code">
<pre>docker pull mongodb:6.0</pre>
</div>
<p>拉取成功后，查看docker镜像</p>
<div class="cnblogs_code">
<pre>docker images</pre>
</div>
<p><img src="https://img2023.cnblogs.com/blog/2661519/202306/2661519-20230629113303035-1447155680.png"></p>
<p>3、本地创建容器卷文件夹</p>
<p>首先在本地创建文件夹</p>
<div class="cnblogs_code">
<pre><span style="color: rgba(0, 0, 0, 1)">D:\mongodb\conf
D:\mongodb\data
D:\mongodb\logs</span></pre>
</div>
<p>进入conf文件夹创建mongod.conf文件</p>
<div class="cnblogs_code">
<pre><span style="color: rgba(0, 0, 0, 1)"># 数据库文件存储位置
dbpath = /data/db
# log文件存储位置
logpath = /data/log/mongod.log<br>#pid运行目录<br>#pidfilepath = /var/run/mongodb/mongodb.pid
# 使用追加的方式写日志
logappend = true<br>#启用日志文件，默认启用<br></span>journal<span class="hljs-operator">=<span class="hljs-keyword">true</span></span></pre>
<pre><span style="color: rgba(0, 0, 0, 1)">#最大连接数<br>maxConns=2048
# 是否以守护进程方式运行
# fork = true
# 全部ip可以访问
bind_ip = 0.0.0.0
# 端口号
port = 27017
# 是否启用认证
auth = true
# 设置oplog的大小(MB)
oplogSize=</span>1755</pre>
<pre></pre>
</div>
<p>进入logs目录文件创建mongod.log文件</p>
<p>4、通过命令创建新容器</p>
<div class="cnblogs_code">
<pre>docker run -d --name mongodb -p 27017:27017 --privileged=true --restart=always <br>-v D:/mongodb/data:/data/db <br>-v D:/mongodb/conf:/data/configdb <br>-v D:/mongodb/logs:/data/log/ <br>-e MONGO_INITDB_ROOT_USERNAME=root <br>-eMONGO_INITDB_ROOT_PASSWORD=1234qwer mongo:6.0<br>-f /data/configdb/mongod.conf --auth</pre>
</div>
<p>-d 后台运行</p>
<p>-p 映射端口</p>
<p>--privileged&nbsp; 以root 用户身份在容器内运行</p>
<p>--restart&nbsp; 自动重启容器</p>
<p>-v 容器卷</p>
<p>-e 设置环境</p>
<p>-f 指明配置文件路径 容器以容器内的配置文件启动</p>
<p>--auth mongo开启安全认证，需要账号密码才能访问</p>
<p>&nbsp;<img src="https://img2023.cnblogs.com/blog/2661519/202306/2661519-20230629133154374-285099969.jpg"></p>
<p>容器启动成功</p>
<p>5、查看mongo版本</p>
<p>进入容器实例</p>
<div class="cnblogs_code">
<pre>docker exec -it cfb571a9a7e4/bin/bash</pre>
</div>
<p>输入命令：</p>
<div class="cnblogs_code">
<pre>mongod -version</pre>
</div>
<p><img src="https://img2023.cnblogs.com/blog/2661519/202306/2661519-20230629133401386-1542222445.png"></p>
<p>docker安装mongodb成功。</p>
<p>6、错误问题</p>
<p>上面我们使用docker安装的mongodb已经可以使用了，但是还有一个问题。如果重新启动容器，会发现容器启动不了。会报错：</p>
<div class="cnblogs_code">

</div>
<p>主要看这条日志：</p>
<div class="cnblogs_code">
<pre>":"E","c":"NETWORK","id":23024,   "ctx":"initandlisten","msg":"Failed to unlink socket file","attr":{"path":"/tmp/mongodb-27017.sock","error":"Operation not permitted"}}</pre>
</div>
<p>发现&nbsp;&nbsp;/tmp/mongodb-27017.sock 没有操作权限，导致容器重新启动失败。</p>
<p>解决方法：</p>
<p>删除mongodb-27017.sock，重启mongo服务。</p>
<div class="cnblogs_code">
<pre>sudo rm /tmp/mongodb-27017.sock</pre>
</div>
<p>因为使用的docker，容器没有运行进入不了容器，所以无法使用。</p>
<p>所以需要使用容器卷映射tmp 使mongodb-27017文件拥有相应权限</p>
<p>增加容器卷：</p>
<div class="cnblogs_code">
<pre> -v D:/mongodb/tmp:/tmp</pre>
</div>
<p>把之前的容器删除，重新启动一个新容器。由于之前使用了容器卷，所以启动新容器数据也不会消失。完整命令：</p>
<div class="cnblogs_code">
<pre>docker run -d --name mongodb -p 27017:27017 --privileged=true <br>-v D:/mongodb/data:/data/db <br>-v D:/mongodb/conf:/data/configdb <br>-v D:/mongodb/logs:/data/log/<br>-v D:/mongodb/tmp:/tmp <br>-e MONGO_INITDB_ROOT_USERNAME=root<br>-eMONGO_INITDB_ROOT_PASSWORD=1234qwer <br>mongo:6.0   <br>-f /data/configdb/mongod.conf --auth</pre>
</div>
<p>启动容器。然后停止容器再次重新启动。发现没有报错问题解决。</p>
