docker下載mongodb鏡像並啟動容器

1、查找mongodb相關鏡像

docker search mongo

找到相關的鏡像進行拉取，如果不指定版本，預設下載最新的mongoDB。建議自己先查找需要那個版本後在進行拉取，因為mongoDB不同版本之間差距較大。

2、拉取鏡像

這裡拉取mongodb6.0

docker pull mongodb:6.0

拉取成功後，查看docker鏡像

docker images

3、本地創建容器捲文件夾

首先在本地創建文件夾

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

進入conf文件夾創建mongod.conf文件

# 資料庫文件存儲位置
dbpath = /data/db
# log文件存儲位置
logpath = /data/log/mongod.log
#pid運行目錄
#pidfilepath = /var/run/mongodb/mongodb.pid
# 使用追加的方式寫日誌
logappend = true
#啟用日誌文件，預設啟用
journal=true

#最大連接數
maxConns=2048
# 是否以守護進程方式運行
# fork = true
# 全部ip可以訪問
bind_ip = 0.0.0.0
# 埠號
port = 27017
# 是否啟用認證
auth = true
# 設置oplog的大小(MB)
oplogSize=1755

進入logs目錄文件創建mongod.log文件

4、通過命令創建新容器

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 後臺運行

-p 映射埠

--privileged  以root 用戶身份在容器內運行

--restart  自動重啟容器

-v 容器捲

-e 設置環境

-f 指明配置文件路徑 容器以容器內的配置文件啟動

--auth mongo開啟安全認證，需要賬號密碼才能訪問

容器啟動成功

5、查看mongo版本

進入容器實例

docker exec -it cfb571a9a7e4  /bin/bash

輸入命令：

mongod -version

docker安裝mongodb成功。

6、錯誤問題

上面我們使用docker安裝的mongodb已經可以使用了，但是還有一個問題。如果重新啟動容器，會發現容器啟動不了。會報錯：

主要看這條日誌：

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

發現  /tmp/mongodb-27017.sock 沒有操作許可權，導致容器重新啟動失敗。

解決方法：

刪除mongodb-27017.sock，重啟mongo服務。

sudo rm /tmp/mongodb-27017.sock

因為使用的docker，容器沒有運行進入不了容器，所以無法使用。

所以需要使用容器捲映射tmp 使mongodb-27017文件擁有相應許可權

增加容器捲：

 -v D:/mongodb/tmp:/tmp

把之前的容器刪除，重新啟動一個新容器。由於之前使用了容器捲，所以啟動新容器數據也不會消失。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

啟動容器。然後停止容器再次重新啟動。發現沒有報錯問題解決。
