docker下载mongodb镜像并启动容器

1、查找mongodb相关镜像

1. docker search mongo

复制代码

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。
2、拉取镜像
这里拉取mongodb6.0

1. docker pull mongodb:6.0

复制代码

拉取成功后，查看docker镜像

1. docker images

复制代码

3、本地创建容器卷文件夹
首先在本地创建文件夹

1. D:\mongodb\conf
2. D:\mongodb\data
3. D:\mongodb\logs

复制代码

进入conf文件夹创建mongod.conf文件

1. # 数据库文件存储位置
2. dbpath = /data/db
3. # log文件存储位置
4. logpath = /data/log/mongod.log<br>#pid运行目录<br>#pidfilepath = /var/run/mongodb/mongodb.pid
5. # 使用追加的方式写日志
6. logappend = true<br>#启用日志文件，默认启用<br>journal=true

复制代码

1. #最大连接数<br>maxConns=2048
2. # 是否以守护进程方式运行
3. # fork = true
4. # 全部ip可以访问
5. bind_ip = 0.0.0.0
6. # 端口号
7. port = 27017
8. # 是否启用认证
9. auth = true
10. # 设置oplog的大小(MB)
11. oplogSize=1755

复制代码

1. [/code]进入logs目录文件创建mongod.log文件
2. 4、通过命令创建新容器
3. [code]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>-e  MONGO_INITDB_ROOT_PASSWORD=1234qwer mongo:6.0  <br>-f /data/configdb/mongod.conf --auth

复制代码

-d 后台运行
-p 映射端口
--privileged  以root 用户身份在容器内运行
--restart  自动重启容器
-v 容器卷
-e 设置环境
-f 指明配置文件路径 容器以容器内的配置文件启动
--auth mongo开启安全认证，需要账号密码才能访问
 
容器启动成功
5、查看mongo版本
进入容器实例

1. docker exec -it cfb571a9a7e4  /bin/bash

复制代码

输入命令：

1. mongod -version

复制代码

docker安装mongodb成功。
6、错误问题
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：

1. {"t":{"$date":"2023-06-29T09:25:48.932+00:00"},"s":"I",  "c":"CONTROL",  "id":20698,   "ctx":"-","msg":"***** SERVER RESTARTED *****"}

复制代码

主要看这条日志：

1. ":"E",  "c":"NETWORK",  "id":23024,   "ctx":"initandlisten","msg":"Failed to unlink socket file","attr":{"path":"/tmp/mongodb-27017.sock","error":"Operation not permitted"}}

复制代码

发现  /tmp/mongodb-27017.sock 没有操作权限，导致容器重新启动失败。
解决方法：
删除mongodb-27017.sock，重启mongo服务。

1. sudo rm /tmp/mongodb-27017.sock

复制代码

因为使用的docker，容器没有运行进入不了容器，所以无法使用。
所以需要使用容器卷映射tmp 使mongodb-27017文件拥有相应权限
增加容器卷：

1. -v D:/mongodb/tmp:/tmp

复制代码

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：

1. 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>-e  MONGO_INITDB_ROOT_PASSWORD=1234qwer <br>mongo:6.0   <br>-f /data/configdb/mongod.conf --auth

复制代码

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。
