#1创建映射目录
mkdir -p /data/mongodb/data
mkdir -p /data/mongodb/log
mkdir -p /data/mongodb/conf


#2修改配置
vi /data/mongodb/conf/mongod.conf

#3.启动容器
docker run -itd \
--name mongo \
--restart always \
--privileged=true \
-p 27017:27017 \
-v /data/mongodb/data:/data/db \
-v /data/mongodb/log:/data/log \
-v /data/mongodb/conf:/data/configdb \
-e TZ=Asia/Shanghai \
mongo:3.4.24 \
-f /data/configdb/mongod.conf

#查看容器
docker ps

#1.登录原有服务器上的mongo
mongo

#2.密码校验
use admin
db.auth("joshua317","password");

#3.查看全局所有账户
db.system.users.find().pretty()

#4.查看当前库下的账户
show users

#5.进入新服务的mongo容器
docker exec -it mongo /bin/bash

#6.登录mongo
mongo

#7.创建用户
use admin
db.createUser({user:'joshua317',pwd:'password', roles:[{role:'root', db:'admin'}]})

use chat
db.createUser({user:'joshua317',pwd:'123456', roles:[{role:'readWrite', db:'chat'}]})


db.auth("joshua317","123456");

#1.登录原有服务器上的mongo
mongo
#2.密码校验
use admin;
db.auth("joshua317","password");
#3.查看数据库
show dbs;
exit;

#4.备份，备份后会生成一个文件夹，对文件夹进行打包并传递到新的服务器
mongodump -d chat -o /root/ -u=josua317 --authenticationDatabase admin

#1.进入新服务的mongo容器
docker exec -it mongo /bin/bash

#恢复数据
mongorestore -d chat /data/db/chat -u josua317 --authenticationDatabase admin
