Mongodb4.4.1分片叢集搭建

阿新 • • 發佈：2020-12-03

1、環境規劃

3臺機，每臺機5個例項，分別mongos 1 個，config server 1 個，shard server 3 個
IP:192.168.56.107(mongodb01) 例項:mongos:30000 shard1:40001(主節點) shard2:40002(仲裁節點) shard3:40003(副節點) config:27027
IP:192.168.56.105(mongodb02) 例項:mongos:30000 shard1:40001(副節點) shard2:40002(主節點) shard3:40003(仲裁節點) config:27028
IP:192.168.56.106(mongodb03) 例項:mongos:30000 shard1:40001(仲裁節點) shard2:40002(副節點) shard3:40003(主節點) config:27029

2、建立相應目錄

在192.168.56.107(mongodb01)上新建：

mkdir -p /mongodb01/{data,logs,apps,run} 
mkdir -p /mongodb01/data/shard{1,2,3} 
mkdir -p /mongodb01/data/config

在192.168.56.105(mongodb02)上新建：

mkdir -p /mongodb02/{data,logs,apps,run} 
mkdir -p /mongodb02/data/shard{1,2,3} 
mkdir -p /mongodb02/data/config

在192.168.56.106(mongodb03)上新建：

mkdir -p /mongodb03/{data,logs,apps,run} 
mkdir -p /mongodb03/data/shard{1,2,3} 
mkdir -p /mongodb03/data/config

3、配置環境變數

使用root賬號修改配置,/mongodb01/apps/bin 用於存放mongodb的執行程式

echo 'export PATH=$PATH:/mongodb01/apps/bin' >> /etc/profile
source /etc/profile

使用root賬號修改配置,/mongodb01/apps/bin 用於存放mongodb的執行程式

echo 'export PATH=$PATH:/mongodb02/apps/bin' >> /etc/profile
source /etc/profile

使用root賬號修改配置,/mongodb01/apps/bin 用於存放mongodb的執行程式

echo 'export PATH=$PATH:/mongodb03/apps/bin' >> /etc/profile
source /etc/profile

4、建立使用者及修改許可權

Mongodb01下：

groupadd -g 10001 mongodb 
useradd -u 10001 -g mongodb mongodb 
id mongodb 
passwd mongodb 
輸入新的密碼：123 
chown -R mongodb:mongodb /mongodb01
chmod -R 775 /mongodb01

Mongodb02下：

groupadd -g 10001 mongodb 
useradd -u 10001 -g mongodb mongodb 
id mongodb 
passwd mongodb 
輸入新的密碼：123 
chown -R mongodb:mongodb /mongodb02
chmod -R 775 /mongodb02

Mongodb03下：

groupadd -g 10001 mongodb 
useradd -u 10001 -g mongodb mongodb 
id mongodb 
passwd mongodb 
輸入新的密碼：123 
chown -R mongodb:mongodb /mongodb03
chmod -R 775 /mongodb03

5、下載安裝檔案

切換使用者：

su mongodb

Mongodb01下:切換目錄:

cd /mongodb01/apps

下載檔案

wget

解壓檔案

tar -xf mongodb-linux-x86_64-rhel70-4.4.1.tgz
mv mongodb-linux-x86_64-rhel70-4.4.1/bin ./
rm -rf mongodb-linux-x86_64-rhel70-4.4.1

Mongodb02下:切換目錄:

cd /mongodb02/apps

下載檔案

wget

解壓檔案

tar -xf mongodb-linux-x86_64-rhel70-4.4.1.tgz
mv mongodb-linux-x86_64-rhel70-4.4.1/bin ./
rm -rf mongodb-linux-x86_64-rhel70-4.4.1

Mongodb03下:切換目錄:

cd /mongodb03/apps

下載檔案

wget

解壓檔案

tar -xf mongodb-linux-x86_64-rhel70-4.4.1.tgz
mv mongodb-linux-x86_64-rhel70-4.4.1/bin ./
rm -rf mongodb-linux-x86_64-rhel70-4.4.1

6、建立配置檔案

Mongodb01下新建檔案目錄：

mkdir -p /mongodb01/apps/conf/
vi /mongodb01/apps/conf/mongodb01-config.yml
echo "systemLog:
  destination: file

# 注意修改路徑

  path: "/mongodb01/logs/mongodb01-config.log" 
  logAppend: true
storage:
  journal:
    enabled: true

#注意修改路徑

  dbPath: "/mongodb01/data/config"

  fork: true
  pidFilePath: "/mongodb01/run/mongodb01-config.pid"

Mongodb4.4.1分片叢集搭建

7、部署配置伺服器叢集(三臺機器都要操作)

啟動config服務（3臺機器執行相同操作,只是在不同的mongodb上啟動時需要修改mongodb0,此處只演示mongodb01上的配置部署）
在mongodb01下

cd /mongodb01/apps/conf/
mongod --config /mongodb01/apps/conf/mongodb01-config.yml

連線一個例項

mongo 192.168.56.107:27027(此處三臺機器一致)

初始化複製集
(這個 mgconfig 名字一定要和config 配置檔案中 replSet 的名字一致)
```config={id:"mgconfig",members:[{id:0,host:"192.168.56.107:27027"},{id:1,host:"192.168.56.105:27028"},{id:2,host:"192.168.56.106:27029"},]}

rs.initiate(config)

檢查狀態

rs.status()


複製集配完後，可能狀態不會馬上改變（可能都是secondary），過幾秒就會自動更新

8、部署shard1分片叢集(3臺機器都要操作，此處只操作mongodb01)

啟動3臺shard1例項

cd /mongodb01/apps/conf/
mongod --config /mongodb01/apps/conf/mongodb01-shard1.yml

連線一個例項

mongo 192.168.56.107:40001(3臺機器一致)

建立複製集

use admin
config={_id:"shard1",members:[{_id:0,host:"192.168.56.107:40001",priority:2},{_id:1,host:"192.168.56.105:40001",priority:1},{_id:2,host:"192.168.56.106:40001",arbiterOnly:true},]}

這個 shard1名字一定要和 shard1配置檔案中 replSet 的名字一致
初始化複製集

rs.initiate(config)

檢查狀態

rs.status()

複製集配完後，可能狀態不會馬上改變（可能都是secondary），過幾秒就會自動更新

9、部署shard2分片叢集(3臺機器都要操作，此處只示範mongodb01)

啟動3臺shard2例項

cd /mongodb01/apps/conf/
mongod --config /mongodb01/apps/conf/mongodb01-shard2.yml

連線第二個節點建立複製集
為什麼是連線第二個，因為規劃的shard2 的主節點是105:40002，仲裁節點不能寫資料，所以這裡不能連107，要連105

mongo 192.168.56.105:40002(三臺機器一致)

建立複製集

use admin
config={_id:"shard2",members:[{_id:0,host:"192.168.56.107:40002",arbiterOnly:true},{_id:1,host:"192.168.56.105:40002",priority:2}, {_id:2,host:"192.168.56.106:40002",priority:1},]}

這個 shard2名字一定要和 shard2配置檔案中 replSet 的名字一致
初始化複製集

rs.initiate(config)

檢查狀態

rs.status()

複製集配完後，可能狀態不會馬上改變（可能都是secondary），過幾秒就會自動更新

10、部署shard3分片叢集(3臺機器都要操作，這裡只示範mongodb01)

啟動3臺shard3例項

cd /mongodb01/apps/conf/
mongod --config /mongodb01/apps/conf/mongodb01-shard3.yml

連線第三個節點建立複製集
為什麼是連線第三個，因為規劃的shard3 的主節點是106:40003

mongo 192.168.56.106:40003(3臺機器一致)

建立複製集

use admin
config={_id:"shard3",members:[{_id:0,host:"192.168.56.107:40003",priority:1},{_id:1,host:"192.168.56.105:40003",arbiterOnly:true}, 
{_id:2,host:"192.168.56.106:40003",priority:2},]}

這個 shard3名字一定要和 shard3配置檔案中 replSet 的名字一致
初始化複製集

rs.initiate(config)

檢查狀態

rs.status()

複製集配完後，可能狀態不會馬上改變（可能都是secondary），過幾秒就會自動更新

11、啟用分片功能

登陸路由節點

cd /mongodb01/apps/conf/
mongos --config /mongodb01/apps/conf/mongodb01-route.yml
mongo 192.168.56.107:30000

use admin
sh.addShard("shard1/192.168.56.107:40001,192.168.56.105:40001,192.168.56.106:40001") 
sh.addShard("shard2/192.168.56.107:40002,192.168.56.105:40002,192.168.56.106:40002") 
sh.addShard("shard3/192.168.56.107:40003,192.168.56.105:40003,192.168.56.106:40003")

檢查狀態

sh.status()

12、服務指令碼

編寫服務指令碼，便於啟動和停止叢集

13、測試伺服器分片功能

模擬寫入資料
在tydb庫的tyuser表中迴圈寫入6萬條資料

mongo 192.168.56.107:30000
use tydb
show collections
for(i=1;i<=60000;i++){db.tyuser.insert({"id":i,"name":"ty"+i})}

啟用資料庫分片

sh.enableSharding("tydb")

建立的索引

db.tyuser.createIndex({"id":1})

啟用表分片

sh.shardCollection(”tydb.tyuser",{"id":1})

檢視分片情況

sh.status()

開啟平衡器

use admin
sh.startBalance()

關閉平衡器

use admin
sh.stopBalancer()

檢視是否關閉
返回flase表示平衡器已關閉，還需要查詢均衡器正在執行的情況

sh.getBalancerState()
