拉取mongo镜像：

启动容器：

初始化admin：

docker run --name txtMongo -p 270127:27017 -v /var/mongo_backup:/data/db -d 71c --auth

use admin
db.createUser(
  {
    user: "txtAdmin",
    pwd: "PivosTxtech07031036",
    roles: [ { role: "userAdminAnyDatabase", db: "admin" } ]
  }
)

（1）重新连接MongoDB数据库

退出容器，重新用下面命令进入容器即可：

docker exec -it mongodb_mongo_1 mongo admin

#———-

Result：

#———- MongoDB shell version: 3.2.12 connecting to: admin

（2）授权登录admin

db.auth('txtAdmin', 'PivosTxtech07031036')

（3）创建访问指定数据库的用户

Step1: switch to the specified database:

use octblog

Step2: create a user

db.createUser(
  {
    user: "txt",
    pwd: "itxtmcc",
    roles: [ { role: "readWrite", db: "txt-lsp-agent-mcc" },
             { role: "readWrite", db: "txt-lsp-agent-mcc-v2" } ]
  }
)

mongodump --collection employee --db mongodevdb --username mongodevdb --password YourSecretPwd --out /dbbackup

Failed: error connecting to db server: server returned error on SASL authentication step: Authentication failed.

solve:

–authenticationDatabase admin

使用指定用户名和备份路径：

docker exec -it d08 mongodump --db txt-lsp-agent-mcc --username txtAdmin --password PivosTxtech07031036 --out /data/db/backup --authenticationDatabase admin

将容器中的mongo数据库备份出来

#!/bin/bash

dbNames="txt-lsp-agent-mcc 
txt-lsp-agent-api
txt-lsp-agent-mcc-v2
txt-lsp-agent-weixin"

for i in $dbNames
do
  docker exec -it d08 mongodump --db $i --username txtAdmin --password PivosTxtech07031036 --out /data/db/backup --authenticationDatabase admin
done

echo; echo "has backup mongodb database in container to /var/mongo_backup/"
exit 0

Daily Note

Result：

将容器中的mongo数据库备份出来
