本次分片集群部署采用 1 个前端路由 (mongos)，3 个分片 (shard)，每个分片 (shard)都有 3 个副本 (replSet)。另外配置服务 (configsvr)也采用了 3 个副本。总启动容器数为 13 个。

前提

安装好 docker 和 docker-compose 的环境，具体安装教程查看链接

下载镜像

  1. docker pull mongo:4.0.10

创建所需的文件和目录

  1. mkdir -p /root/softdata/mongo # 工作目录
  2. cd /root/softdata/mongo
  3. touch docker-compose.yaml # docker-compose 启动文件
  4. touch docker-compose-auth.yaml # 启用用户授权的 docker-compose 文件
  5. openssl rand -base64 753  > keyfile # 创建授权秘钥文件
  6. chmod 400 keyfile # 修改权限

编写 docker-compose 文件

  9. mongos> sh.status()  # 查看集群状态

创建相关用户

创建 root管理员账户

  1. # 进入前端路由 mongos 容器
  2. docker exec -it mongos bash
  3. # 登陆数据库
  4. mongo
  5. mongos> use admin # 使用 admin 数据库
  6. mongos> db.createUser({user: "admin",pwd: "123456",roles: [{ role: "root", db: "admin" }]}) # root所有权限
  7. mongos> use config # 使用 config 数据库
  8. mongos> db.createUser({user: "admin",pwd: "123456",roles: [{ role: "root", db: "admin" }]}) # root所有权限
  9. mongos> db.auth("admin","123456")  # 登陆认证，返回1为验证成功

创建集群管理员账户

  1. # 接着上一步
  2. mongos> use admin 
  3. mongos> db.createUser({user:"clusterManager",pwd:"123456",roles:[
  4.     {role:"clusterAdmin", db: "admin"},
  5.     {role:"readWriteAnyDatabase", db: "admin"},
  6.     {role:"dbOwner", db: "local"},
  7.     {role:"userAdminAnyDatabase", db: "admin"},
  8. ]})

创建 shard1 分片管理员账户

  1. # 进入 shard1 的副本集的主节点容器
  2. docker exec -it mongo-shard1-rs1 bash 
  3. # 登陆数据库
  4. mongo --port 27018 
  5. shard1:PRIMARY> use admin
  6. shard1:PRIMARY> db.createUser({user:"shardManager",pwd:"123456",roles:[
  7.     {role:"clusterAdmin", db: "admin"},
  8.     {role:"readWriteAnyDatabase", db: "admin"},
  9.     {role:"dbOwner", db: "local"},
  10.     {role:"userAdminAnyDatabase", db: "admin"},
  11. ]})

创建 shard2 分片管理员账户

  1. # 进入 shard2 的副本集的主节点容器
  2. docker exec -it mongo-shard2-rs1 bash 
  3. # 登陆数据库
  4. mongo --port 27018 
  5. shard2:PRIMARY> use admin
  6. shard2:PRIMARY> db.createUser({user:"shardManager",pwd:"123456",roles:[
  7.     {role:"clusterAdmin", db: "admin"},
  8.     {role:"readWriteAnyDatabase", db: "admin"},
  9.     {role:"dbOwner", db: "local"},
  10.     {role:"userAdminAnyDatabase", db: "admin"},
  11. ]})

创建 shard3 分片管理员账户

  1. # 进入 shard3 的副本集的主节点容器
  2. docker exec -it mongo-shard3-rs1 bash 
  3. # 登陆数据库
  4. mongo --port 27018 
  5. shard3:PRIMARY> use admin
  6. shard3:PRIMARY> db.createUser({user:"shardManager",pwd:"123456",roles:[
  7.     {role:"clusterAdmin", db: "admin"},
  8.     {role:"readWriteAnyDatabase", db: "admin"},
  9.     {role:"dbOwner", db: "local"},
  10.     {role:"userAdminAnyDatabase", db: "admin"},
  11. ]})

注意：在分片上创建管理员账户一定要在主节点上，也就是需要在PRIMARY上创建，而不能在SECONDARY上，否则无法创建；这里 3 个分片创建的管理员账户相同，是为了使用 mongo-connector 等共计做数据同步需要。

启用用户登录授权

  1. # 使用 docker-compose-auth.yaml 文件重启所有容器
  2. docker-compose -f docker-compose-auth.yaml restart

验证授权

  1. # 进入前端路由 mongos 容器
  2. docker exec -it mongos bash
  3. # 登陆数据库
  4. mongo
  5. mongos> use admin # 使用 admin 数据库
  6. mongos> sh.status() # 现在无法查看分片状态，提示需要登录
  7. mongos> db.auth("admin","123456")  # 登陆认证，返回1为验证成功
  8. mongos> sh.status() # 再次执行，可以查看分片状态

插入数据验证分片集群

创建 testdb 数据库实例，并启用分片

  1. # 创建 testdb 数据库实例
  2. mongos> use testdb
  3. mongos> sh.enableSharding("testdb") # 启用分片
  4. # 创建集合 book，为其执行分片初始化
  5. mongos> use testdb
  6. mongos> db.createCollection("book")
  7. mongos> db.device.ensureIndex({createTime:1})
  8. mongos> sh.shardCollection("appdb.book", {bookId:"hashed"}, false, { numInitialChunks: 4})

往book集合写入 50000条记录，观察chunks的分布情况!

  1. mongos> use testdb
  2. mongos> var cnt = 0;
  3. mongos> for(var i=0; i<100; i++){
  4.    var dl = [];
  5.    for(var j=0; j<500; j++){
  6.        dl.push({
  7.                "bookId" : "BBK-" + i + "-" + j,
  8.                "type" : "Revision",
  9.                "version" : "IricSoneVB"+j,
  10.                "title" : "这是一本书哦",
  11.                "subCount" : 10,
  12.                "location" : "北京市朝阳区望京SOHO",
  13.                "author" : {
  14.                      "name" : "dmego",
  15.                      "email" : "dmeago@gmail.com",
  16.                      "gender" : "female"
  17.                },
  18.                "createTime" : new Date()
  19.            });
  20.      }
  21.      cnt += dl.length;
  22.      db.book.insertMany(dl);
  23.      print("insert ", cnt);
  24. }

执行db.book.getShardDistribution() 查看分片情况
执行 db.book.stats() 查看 book 集合状态
