docker下载mongodb镜像并启动容器

1、查找mongodb相关镜像

docker search mongo

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

docker pull mongodb:6.0

拉取成功后，查看docker镜像

docker images

3、本地创建容器卷文件夹

首先在本地创建文件夹

D:\mongodb\conf
D:\mongodb\data
D:\mongodb\logs

进入conf文件夹创建mongod.conf文件

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


#最大连接数  
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=1755

进入logs目录文件创建mongod.log文件

4、通过命令创建新容器

docker run -d --name mongodb -p 27017:27017 --privileged=true --restart=always   
-v D:/mongodb/data:/data/db   
-v D:/mongodb/conf:/data/configdb   
-v D:/mongodb/logs:/data/log/   
-e MONGO_INITDB_ROOT_USERNAME=root   
-e  MONGO_INITDB_ROOT_PASSWORD=1234qwer mongo:6.0    
-f /data/configdb/mongod.conf --auth

-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

docker exec -it cfb571a9a7e4  /bin/bash

输入命令：

mongod -version

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：

主要看这条日志：

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

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。

sudo rm /tmp/mongodb-27017.sock

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：

 -v D:/mongodb/tmp:/tmp

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：

docker run -d --name mongodb -p 27017:27017 --privileged=true   
-v D:/mongodb/data:/data/db   
-v D:/mongodb/conf:/data/configdb   
-v D:/mongodb/logs:/data/log/    
-v D:/mongodb/tmp:/tmp   
-e MONGO_INITDB_ROOT_USERNAME=root    
-e  MONGO_INITDB_ROOT_PASSWORD=1234qwer   
mongo:6.0     
-f /data/configdb/mongod.conf --auth

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。
