在Docker中安装MongoDB

只是个称呼而已 發表於 2020-5-12 15:31:00

<h2>1.版本选取</h2>
<div>访问mongodb的镜像仓库地址：https://hub.docker.com/_/mongo?tab=tags&page=1</div>
<div><img src="https://note.youdao.com/yws/public/resource/24f69daff592cd91fe6d86c385feff37/xmlnote/F827ED471CBE44D9B3BF915F9954840E/6888" alt="" width="939" height="695" data-media-type="image" data-original="https://note.youdao.com/yws/public/resource/24f69daff592cd91fe6d86c385feff37/xmlnote/F827ED471CBE44D9B3BF915F9954840E/6888"></div>
<div> </div>
<div>这里选取最新版本进行安装，如果想安装其他的可用版本，可以使用命令“docker search mongo”来查看</div>
<div><img src="https://note.youdao.com/yws/public/resource/24f69daff592cd91fe6d86c385feff37/xmlnote/4ED03D7AEBAF4563B792602C9F25FD14/6886" alt="" data-media-type="image" data-original="https://note.youdao.com/yws/public/resource/24f69daff592cd91fe6d86c385feff37/xmlnote/4ED03D7AEBAF4563B792602C9F25FD14/6886"></div>
<div> </div>
<h2>2.拉取最新版本镜像</h2>
<div>这里执行命令"sudo docker pull mongo:latest" 拉取最新版的mongodb镜像文件</div>
<div><img src="https://note.youdao.com/yws/public/resource/24f69daff592cd91fe6d86c385feff37/xmlnote/E3F4F098BC1A48F8B99443B3CAF71555/6887" alt="" data-media-type="image" data-original="https://note.youdao.com/yws/public/resource/24f69daff592cd91fe6d86c385feff37/xmlnote/E3F4F098BC1A48F8B99443B3CAF71555/6887"></div>
<div> </div>
<div>等待镜像拉取完成后，通过命令"sudo docker images"查看下拉取的镜像，可以看到，已经成功拉取到了本地</div>
<div><img src="https://note.youdao.com/yws/public/resource/24f69daff592cd91fe6d86c385feff37/xmlnote/796C1374741C47F4B59C93C858438E04/6889" alt="" data-media-type="image" data-original="https://note.youdao.com/yws/public/resource/24f69daff592cd91fe6d86c385feff37/xmlnote/796C1374741C47F4B59C93C858438E04/6889"></div>
<div> </div>
<h2>3.开始运行</h2>
<div>创建一个文件夹，用作mongodb的数据目录挂载</div>
<div><img src="https://note.youdao.com/yws/public/resource/24f69daff592cd91fe6d86c385feff37/xmlnote/AA8A3D166737487C96CD7A0A370F7D9B/6891" alt="" data-media-type="image" data-original="https://note.youdao.com/yws/public/resource/24f69daff592cd91fe6d86c385feff37/xmlnote/AA8A3D166737487C96CD7A0A370F7D9B/6891"></div>
<div> </div>
<div>运行启动命令“docker run -p 27017:27017 -v /data/mongo:/data/db --name mongodb -d mongo”</div>
<div><img src="https://img2020.cnblogs.com/blog/645287/202005/645287-20200512162016892-1127181293.png" alt=""></div>
<div><span style="background-color: rgba(255, 255, 255, 1)">在上面的命令中，几个命令参数的详细解释如下：</span></div>
<div><span style="background-color: rgba(255, 255, 255, 1)">-p 映射容器服务的 27017 端口到宿主机的 27017 端口。外部可以直接通过宿主机 ip:27017 访问到 mongo 的服务</span></div>
<div><span style="background-color: rgba(255, 255, 255, 1)">-v 为设置容器的挂载目录，这里是将本机的“/data/mongo”目录挂载到容器中的/data/db中，作为 mongodb 的存储目录</span></div>
<div><span style="background-color: rgba(255, 255, 255, 1)">--name 为设置该容器的名称</span></div>
<div><span style="background-color: rgba(255, 255, 255, 1)">-d 设置容器以守护进程方式运行</span></div>
<div> </div>
<div>通过命令“docker ps”查看容器启动运行情况</div>
<div><img src="https://note.youdao.com/yws/public/resource/24f69daff592cd91fe6d86c385feff37/xmlnote/AEDD8C358A9D44DBAA16BA7BA0AB686C/6898" alt="" width="1063" height="48" data-media-type="image" data-original="https://note.youdao.com/yws/public/resource/24f69daff592cd91fe6d86c385feff37/xmlnote/AEDD8C358A9D44DBAA16BA7BA0AB686C/6898"></div>
<div>可以看到mongo容器已经成功运行起来了</div>
<div> </div>
<h2>4.使用客户端工具Studio 3T连接mongo</h2>
<div>studiot 3T下载地址:https://studio3t.com/download/</div>
<div><img src="https://note.youdao.com/yws/public/resource/24f69daff592cd91fe6d86c385feff37/xmlnote/7E621AD5376D4D75BA98C75390C0719D/6906" alt="" width="978" height="688" data-media-type="image" data-original="https://note.youdao.com/yws/public/resource/24f69daff592cd91fe6d86c385feff37/xmlnote/7E621AD5376D4D75BA98C75390C0719D/6906"></div>
<div> </div>
<div><img src="https://note.youdao.com/yws/public/resource/24f69daff592cd91fe6d86c385feff37/xmlnote/BB05EDFE92F5447EA1A368DEA77B7338/6908" alt="" width="322" height="556" data-media-type="image" data-original="https://note.youdao.com/yws/public/resource/24f69daff592cd91fe6d86c385feff37/xmlnote/BB05EDFE92F5447EA1A368DEA77B7338/6908"></div>
<div> </div>
<h2>5.创建mongo用户</h2>
<div>可以看到一个空的mongo数据库，有一个不太完美的地方在于我们的mongo没有任何账户密码，在裸奔，下面我们执行以下语句，创建一个管理员用户，</div>
<div>
<div class="cnblogs_Highlighter">
<pre class="brush:csharp;gutter:true;">db.createUser({
user: 'admin',
pwd: 'Aa123456',
roles: [ { role: "userAdminAnyDatabase", db: "admin" } ]
});　</pre>
</div>
</div>
<div><img src="https://note.youdao.com/yws/public/resource/24f69daff592cd91fe6d86c385feff37/xmlnote/280AFE897C584ECCB01D36E997C4906B/6927" alt="" data-media-type="image" data-original="https://note.youdao.com/yws/public/resource/24f69daff592cd91fe6d86c385feff37/xmlnote/280AFE897C584ECCB01D36E997C4906B/6927"></div>
<div> </div>
<h2>6.指定auth重新运行服务</h2>
<div>创建完用户我们就要重新启动mongo服务，并且指定auth</div>
<div>删除已经运行的mongo容器：docker rm -f mongodb</div>
<div>指定验证启动mongo容器：docker run -p 27017:27017 -v /data/mongo:/data/db --name mongodb -d mongo --auth</div>
<div>也就是在之前的启动命令后面加上 --auth：需要密码才能访问容器服务</div>
<div> </div>
<div>此时强行访问，可以看到提示，没有授权</div>
<div><img src="https://note.youdao.com/yws/public/resource/24f69daff592cd91fe6d86c385feff37/xmlnote/62755B6BE10E4C44BFA6F73E9D8C002D/6978" alt="" data-media-type="image" data-original="https://note.youdao.com/yws/public/resource/24f69daff592cd91fe6d86c385feff37/xmlnote/62755B6BE10E4C44BFA6F73E9D8C002D/6978"></div>
<div> </div>
<div>这里我们在连接的地方指定一下账户密码</div>
<div><img src="https://note.youdao.com/yws/public/resource/24f69daff592cd91fe6d86c385feff37/xmlnote/F59DCC685A834C429635F9799F6C8198/6947" alt="" width="854" height="588" data-media-type="image" data-original="https://note.youdao.com/yws/public/resource/24f69daff592cd91fe6d86c385feff37/xmlnote/F59DCC685A834C429635F9799F6C8198/6947"></div>
<div> </div>
<div>再来查询，已经正确查询出来之前添加的用户信息</div>
<div><img src="https://note.youdao.com/yws/public/resource/24f69daff592cd91fe6d86c385feff37/xmlnote/FC8E0591E02E4E799883EE4F181EF5F2/6986" alt="" data-media-type="image" data-original="https://note.youdao.com/yws/public/resource/24f69daff592cd91fe6d86c385feff37/xmlnote/FC8E0591E02E4E799883EE4F181EF5F2/6986"></div>
