1. Preliminary preparation

You can download the MongoDB image from the repository before a new deployment, or generate files from the image in an existing deployment:

# 查看当前本地镜像
docker images
# 生成本地镜像文件
docker save <IMAGE ID> -o mongodb_3015.tar

Autokey files required to generate a MongoDB replica set:

# 建立autokey文件
openssl rand -base64 756 > autokey
# 修改读写模式
chmod 400 autokey

2. Import the image

# 在新部署的机器上导入镜像
docker load -i mongodb_3015.tar
docker images

3. Deploy MongoDB script

The contents of the mongodb-deploy.sh file are as follows:

#!/bin/bash

mkdir -p /usr/local/docker/mongodb/conf
mkdir -p /usr/local/docker/mongodb/data
cp /root/autokey /usr/local/docker/mongodb/data/
cp /root/mongodb.conf.template /usr/local/docker/mongodb/conf/mongodb.conf
chown -R polkitd:root /usr/local/docker/mongodb/

docker run --name mongo \
-v /usr/local/docker/mongodb/data:/data/db \
-v /usr/local/docker/mongodb/conf:/data/conf \
-p 27017:27017 \
-e TZ=Asia/Shanghai \
-itd a.com:8443/dockerhub/mongo:3.0.15 \
--replSet mvbox_new

4. Configure template file

The contents of the mongodb.conf.template file are as follows:

port            = 27017
logpath         = /data/db/mongodb.log
pidfilepath     = /data/db/mongodb.pid
dbpath          = /data/db/
logappend       = true
fork            = true
journal         = true
directoryperdb  = true
auth            = true
maxConns        = 1000
profile         = 1
replSet         = mvbox_new
keyFile         = /data/db/autokey

5. Deploy MongoDB

# 在所有 MongoDB 副本集机器执行
./mongodb-deploy.sh

6. Post-deployment configuration

Perform the following operations on the primary machine.

# 配置副本集
cp /root/rs_initiate.js /usr/local/docker/mongodb/data/
docker exec -it mongo mongo --port 27017 /data/db/rs_initiate.js

The contents of the rs_initiate.js file are as follows:

rs.initiate(
   {
      _id: "mvbox_new",
      version: 1,
      members: [
         { _id: 0, host : "172.18.29.56:27017", priority:2 },
         { _id: 1, host : "172.18.29.57:27017", priority:1 },
         { _id: 2, host : "172.18.29.58:27017", priority:1 }
      ]
   }
)

# 创建 admin 用户
docker exec -it mongo mongo --port 27017

use admin;
db.createUser({user : "admin", pwd : "123456", roles: [ { role : "root", db : "admin" } ] });
exit;

# 重新登录，创建更多用户
docker exec -it mongo mongo --port 27017 -u admin -p 123456 admin

use admin
db.createUser({user : "vvmusic_msg", pwd : "123456", roles: [ { role : "dbOwner", db : "vvmusic_msg" } ] });
db.createUser({user : "vvlive", pwd : "123456", roles: [ { role : "dbOwner", db : "vvlive" } ] });
use vvmusic_msg
db.createUser({user : "vvmusic_msg", pwd : "123456", roles: [ { role : "dbOwner", db : "vvmusic_msg" } ] });
use vvlive
db.createUser({user : "vvlive", pwd : "3123456", roles: [ { role : "dbOwner", db : "vvlive" } ] });
exit;

# 验证用户登录
docker exec -it mongo mongo --port 27017 -u admin -p 123456 admin
docker exec -it mongo mongo --port 27017 -u vvlive -p 123456 admin
docker exec -it mongo mongo --port 27017 -u vvlive -p 123456 vvlive
docker exec -it mongo mongo --port 27017 -u vvmusic_msg -p 123456 admin
docker exec -it mongo mongo --port 27017 -u vvmusic_msg -p 123456 vvmusic_msg

7. Basic maintenance

# 查看镜像
docker images
# 查看容器
