1、安裝背景

由於原開發伺服器mongodb資料庫為單機安裝，為了提高訪問效率和資料安全性，需要配置成單機分片叢集。

1.1 實驗環境

1.1.1 分片叢集架構官圖

1.1.2 實驗主機
主機 IP
CentOS 7.4 66.1.30.31
1.1.3 埠規劃
伺服器 埠
route1 27017
conf1 29010
conf2 29011
conf3 29012
shard1_primary 27010
shard1_secondary 27011
shard1_arbiter 27012
shard2_primary 28010
shard2_secondary 28011
shard2_arbiter 28012

1.2 安裝包下載

mongodb-linux-x86_64-rhel70-4.4.2.tgz

1.3配置環境變數

[root@bdp-fmq05 ~]# vim /etc/profile
在 /etc/profile 配置檔案中新增 MongoDB 環境變數，內容如下：
export MONGODB_HOME=/opt/mongodb
export PATH=$MONGODB_HOME/bin:$PATH
[root@bdp-fmq05 ~]# source /etc/profile

2、部署分片

4、mongos路由配置

4.1埠及檔案路徑配置

4.1.1 pid檔案路徑

[root@bdp-fmq05 mongos]# touch /data/mongos/keyfile/autokey

4.2 keyfile檔案路徑

寫入autokey(可以直接拷貝上面生成檔案，全域性key保持一致)

[root@bdp-fmq05 keyfile]# cp /data/keyfile/autokey27010/autokey /data/mongos/keyfile/autokey
cp: overwrite ‘/data/mongos/keyfile/autokey’? y
[root@bdp-fmq05 keyfile]# chmod 400 /data/mongos/keyfile/autokey

4.3 mongos配置檔案

  • route-yaml配置檔案
[root@bdp-fmq05 mongos]# vi /opt/mongoroute/mongoroute.yaml
sharding:
    configDB: config/192.168.17.160:29010,192.168.17.160:29011,192.168.17.160:29012
net:
    port: 27017
    bindIp: 0.0.0.0
 
systemLog:
    destination: file
    logAppend: true
    path: /data/mongos/log/route.log
 
processManagement:
    fork: true
    pidFilePath: /data/mongos/pidfile/mongos.pid
    timeZoneInfo: /usr/share/zoneinfo
 
security:
  keyFile: /data/mongos/keyfile/autokey

5、配置伺服器、分片配置啟動

5.1 啟動服務

按順序依次啟動所有分片副本集（rs-1,rs-2）和配置伺服器(config)和mongos路由3

5.1.1啟動配置伺服器（config）
  • 先將yaml配置檔案中security部分註釋掉，然後啟動
[root@bdp-fmq05 opt]# mongod -f /opt/configsvr/conf29010/config29010.yaml
[root@bdp-fmq05 opt]# mongod -f /opt/configsvr/conf29011/config29011.yaml
[root@bdp-fmq05 opt]# mongod -f /opt/configsvr/conf29012/config29012.yaml
  • 登入，進行初始化

注意 _id:副本集名稱要和config.yaml中的replSetName配置名稱相同; 只需初始化一次即可

檢視rs.status()時出現 "could not find member to sync from" ，等待一會就好了

回車等一會就會出現 "PRIMARY"

[root@bdp-fmq05 /]# mongo --port 29010
> rs.initiate({_id: "config",configsvr: true,members: [{ _id : 0, host : "66.1.30.31:29010" },{ _id : 1, host : "66.1.30.31:29011" },{ _id : 2, host : "66.1.30.31:29012" }]})
{
        "ok" : 1,
        "$gleStats" : {
                "lastOpTime" : Timestamp(1609244619, 1),
                "electionId" : ObjectId("000000000000000000000000")
        },
        "lastCommittedOpTime" : Timestamp(0, 0),
        "$clusterTime" : {
                "clusterTime" : Timestamp(1609244619, 1),
                "signature" : {
                        "hash" : BinData(0,"AAAAAAAAAAAAAAAAAAAAAAAAAAA="),
                        "keyId" : NumberLong(0)
                }
        },
        "operationTime" : Timestamp(1609244619, 1)
}
  • 檢視叢集狀態
config:PRIMARY> rs.status();
{
        "set" : "config",
        "date" : ISODate("2020-12-29T12:23:56.203Z"),
        "myState" : 1,
        "term" : NumberLong(1),
        "syncSourceHost" : "",
        "syncSourceId" : -1,
        "configsvr" : true,
        "heartbeatIntervalMillis" : NumberLong(2000),
        "majorityVoteCount" : 2,
        "writeMajorityCount" : 2,
        "votingMembersCount" : 3,
        "writableVotingMembersCount" : 3,
        "optimes" : {
                "lastCommittedOpTime" : {
                        "ts" : Timestamp(1609244635, 1),
                        "t" : NumberLong(1)
                },
                "lastCommittedWallTime" : ISODate("2020-12-29T12:23:55.675Z"),

  • 為config叢集新增root使用者

1、這裡必須要連線到primary節點下建立使用者,在secondary節點上建立使用者會報錯

2、連線上primary節點後,一定要切換到admin資料庫下建立root許可權使用者

config:PRIMARY> use admin
switched to db admin
config:PRIMARY> db.createUser({user: "cy_admin",pwd: "Admin@12341234",roles: [ { role: "root", db: "admin" } ]});
Successfully added user: {
        "user" : "cy_admin",
        "roles" : [
                {
                        "role" : "root",
                        "db" : "admin"
                }
        ]
}
config:PRIMARY> quit()
  • kill掉mongod服務程序,把config.yaml配置檔案中的security認證註釋開啟,重啟mongod服務
[root@bdp-fmq05 db]# kill `ps -ef|grep mongo|awk {'print $2'}`
[root@bdp-fmq05 db]# mongod -f /opt/configsvr/conf29010/config29010.yaml
[root@bdp-fmq05 db]# mongod -f /opt/configsvr/conf29011/config29011.yaml
[root@bdp-fmq05 db]# mongod -f /opt/configsvr/conf29012/config29012.yaml
  • 輸出如下
 #連線到mongod伺服器
[root@bdp-fmq05 db]# mongo --port 29010
 #切換到admin資料庫
config:PRIMARY> use admin
switched to db admin
 #登入，返回1說明登入成功
config:PRIMARY> db.auth('cy_admin','Admin@12341234')
1

 #登陸後驗證
config:PRIMARY> show dbs;
admin   0.000GB
config  0.000GB
local   0.000GB
config:PRIMARY> rs.status()

5.1.2 啟動分片副本集Ⅰ
  • 使用yaml檔案啟動，先註釋掉sercurity認證
[root@bdp-fmq05 db]# mongod -f /opt/mongos/conf27010/shard27010.yaml
[root@bdp-fmq05 db]# mongod -f /opt/mongos/conf27011/shard27011.yaml
[root@bdp-fmq05 db]# mongod -f /opt/mongos/conf27012/shard27012.yaml
  • 初始化(一主一從一仲裁）
[root@bdp-fmq05 db]# mongo --port 27010
 #注意 _id:副本集名稱要和shard.yaml中的replSetName配置相同;
> rs.initiate({_id : "shard1",members: [{ _id : 0, host : "66.1.30.31:27010" ,priority : 2 },{ _id : 1, host : "66.1.30.31:27011" ,priority : 1 },{ _id : 2, host : "66.1.30.31:27012" ,arbiterOnly :true }]})

5.1.4 啟動route路由叢集

啟動route路由叢集並整合conf叢集和shard叢集

  • 啟動route

注意:這裡啟動的時候和config叢集shard叢集不同,這裡的security認證要開啟,不然會報錯

[root@bdp-fmq05 /]# mongos -f /opt/mongoroute/mongoroute.yaml
  • 連線到mongo路由： 這裡的登入密碼就是config叢集配置的使用者名稱和密碼;埠為定義的27017，可以不指定，使用cy_admin賬戶登陸：
[root@bdp-fmq05 /]# mongo
 #切換到admin資料庫
mongos> use admin
switched to db admin
 #登入，返回1說明登入成功
mongos> db.auth('cy_admin','Admin@12341234')

5.1.5 新增shard分片叢集

把shard1、shard2分片叢集都新增進去,每個分片新增一個節點即可，主或從都可以

mongos> use admin

                }
        }
}

        }
}
  • 檢視叢集狀態
mongos> use admin

        "clusterId" : ObjectId("5feb1fd5d08cb972b338cd4e")
  }
  shards:

至此一個帶有許可權控制的可水平擴容的分片mongodb4.4.2版本叢集搭建完成。

6、資料匯入匯出

6.1 mongodb4.4版本單機資料備份

6.1.1匯出全部資料：
[root@bdp-fmq05 /]# mongodump --host=127.0.0.1 --port=27017 -o /home/mongodback/
6.1.2匯入全部資料：
[root@bdp-fmq05 /]# mongorestore --dir /data/mongoback/mongodback/ -u cy_admin -p Admin@12341234 --authenticationDatabase admin

6.2 開啟均衡器和分片功能

  • 開啟均衡器
mongos> sh.startBalancer()
{
	"ok" : 1,
	"operationTime" : Timestamp(1592882192, 3),
	"$clusterTime" : {
		"clusterTime" : Timestamp(1592882192, 3),
		"signature" : {
			"hash" : BinData(0,"Irm0/RdXjYrJFzPNicDZKZiZy3w="),
			"keyId" : NumberLong("6841344940694306847")
		}
	}
}
 
檢視結果：
mongos> sh.status()
  • 開啟文件分片功能(對匯入的文件)
mongos> use admin
switched to db admin
mongos> show dbs
mongos> db.runCommand({enablesharding:"test"})
mongos> db.runCommand( { shardCollection : "test.fs.chunks" , key : { files_id : 1 , n : 1 } } )

6.3 資料庫配置sharding:

 #允許hyq1225資料庫進行sharding
mongos> sh.enableSharding("hyq1225")
 #對hyq1225.hyq1225集合以id列為shard key進行hashed sharding
mongos> sh.shardCollection("hyq1225.hyq1225",{id:"hashed"})
 #通過db.t.getIndexes()可以看到自動為id列建立了索引。
mongos> db.hyq1225.getIndexes()
 #在不同shard的primary上使用db.hyq1225.find().count()
mongos> db.hyq1225.find().count()
 #檢視分片結果
mongos> db.hyq1225.stats()
 #檢視本庫內所有集合的分片資訊
mongos> sh.status()

 #如果資料庫沒有開啟分片功能，需要先開啟
mongos> sh.enableSharding("hyq1225")
 #如果collection裡面已經有資料，需要先建立對應的shardkey索引
mongos> use hyq1225
mongos> db.myCollection.createIndex( {"id": "hashed"} )
 #對指定collection開啟shard
mongos> sh.shardCollection("hyq1225.hyq1225", {"id": "hashed"})
