MongoDB分片集群部署詳解

一、環(huán)境說(shuō)明

1、我們prod環(huán)境MongoDB的集群架構(gòu)是做的分片集群的部署，但是目前我們沒(méi)有分片，即所有數(shù)據(jù)都在一個(gè)分片上，后期如果數(shù)量大，需要分配，集群隨時(shí)可以分片，對(duì)業(yè)務(wù)方透明

2、各個(gè)角色的部署情況

角色	IP	端口	復(fù)制集名稱(chēng)
mongos	172.21.244.101，172.21.244.102，172.21.244.94	27000	無(wú)
config server	172.21.244.101，172.21.244.102，172.21.244.94	27100	repl_configsvr
存儲(chǔ)節(jié)點(diǎn)（shard）	172.21.244.101，172.21.244.102，172.21.244.94	27101	shard1

3、MongoDB版本

mongos> db.version()
4.0.4-62-g7e345a7

二、基礎(chǔ)信息準(zhǔn)備

0、系統(tǒng)優(yōu)化

echo "never" >/sys/kernel/mm/transparent_hugepage/enabled
echo "never" >/sys/kernel/mm/transparent_hugepage/defrag

1、下載MongoDB二進(jìn)制文件

cd /chj/app
wget ops.chehejia.com:9090/pkg/chj_mongodb_4.0.4.tar.gz
tar -zxvf chj_mongodb_4.0.4.tar.gz

2、相關(guān)目錄建立

#建立base目錄
mkdir /chj/data/mongodb/chj_db
#把MongoDB二進(jìn)制文件移動(dòng)到base目錄下的bin文件夾
mv chj_mongodb_4.0.4/bin /chj/data/mongodb/chj_db/bin
#建立認(rèn)證文件目錄
mkdir /chj/data/mongodb/chj_db/auth
#建立配置文件目錄
mkdir /chj/data/mongodb/chj_db/conf
#建立config server的data和日志目錄
mkdir /chj/data/mongodb/chj_db/config/data -p
mkdir /chj/data/mongodb/chj_db/config/log
#建立mongos的日志目錄
mkdir /chj/data/mongodb/chj_db/mongos/log -p
#建立數(shù)據(jù)節(jié)點(diǎn)data和日志目錄 
mkdir /chj/data/mongodb/chj_db/shard1/data -p
mkdir /chj/data/mongodb/chj_db/shard1/log

3、相關(guān)配置文件編寫(xiě)

A、mongos的配置文件編寫(xiě)

vim /chj/data/mongodb/chj_db/conf/mongos.conf
systemLog:
 destination: file
 logAppend: true
 path: /chj/data/mongodb/chj_db/mongos/log/mongos.log

processManagement:
 fork: true # fork and run in background
 pidFilePath: /chj/data/mongodb/chj_db/mongos/log/mongos.pid # location of pidfile
 timeZoneInfo: /usr/share/zoneinfo

net:
 port: 27000
 bindIpAll: true
 maxIncomingConnections: 1000
 unixDomainSocket:
  enabled: true
  pathPrefix: /chj/data/mongodb/chj_db/mongos/log
  filePermissions: 0700

security:
 keyFile: /chj/data/mongodb/chj_db/auth/keyfile.key
# authorization: enabled

#replication:

sharding:
 configDB: repl_configsvr/172.21.244.101:27100,172.21.244.102:27100,172.21.244.94:27100

B、config server的配置文件編寫(xiě)

vim /chj/data/mongodb/chj_db/conf/config.conf
systemLog:
 destination: file
 logAppend: true
 path: /chj/data/mongodb/chj_db/config/log/congigsrv.log

storage:
 dbPath: /chj/data/mongodb/chj_db/config/data
 journal:
  enabled: true
 wiredTiger:
  engineConfig:
   directoryForIndexes: true

processManagement:
 fork: true # fork and run in background
 pidFilePath: /chj/data/mongodb/chj_db/config/log/configsrv.pid # location of pidfile
 timeZoneInfo: /usr/share/zoneinfo

net:
 port: 27100
 bindIp: 0.0.0.0 # Enter 0.0.0.0,:: to bind to all IPv4 and IPv6 addresses or, alternatively, use the net.bindIpAll setting.
 #bindIpAll: true
 maxIncomingConnections: 1000
 unixDomainSocket:
  enabled: true
  pathPrefix: /chj/data/mongodb/chj_db/config/data
  filePermissions: 0700

security:
 keyFile: /chj/data/mongodb/chj_db/auth/keyfile.key
 authorization: enabled

replication:
 replSetName: repl_configsvr
sharding:
 clusterRole: configsvr

C、存儲(chǔ)節(jié)點(diǎn)的配置文件編寫(xiě)

vim /chj/data/mongodb/chj_db/conf/shard1.conf
systemLog:
 destination: file
 logAppend: true
 path: /chj/data/mongodb/chj_db/shard1/log/shard1.log

storage:
 dbPath: /chj/data/mongodb/chj_db/shard1/data
 journal:
  enabled: true
 wiredTiger:
  engineConfig:
   directoryForIndexes: true

processManagement:
 fork: true # fork and run in background
 pidFilePath: /chj/data/mongodb/chj_db/shard1/log/shard1.pid # location of pidfile
 timeZoneInfo: /usr/share/zoneinfo

net:
 port: 27101
 bindIp: 0.0.0.0 # Enter 0.0.0.0,:: to bind to all IPv4 and IPv6 addresses or, alternatively, use the net.bindIpAll setting.
 #bindIpAll: true
 maxIncomingConnections: 1000
 unixDomainSocket:
  enabled: true
  pathPrefix: /chj/data/mongodb/chj_db/shard1/data
  filePermissions: 0700

security:
 keyFile: /chj/data/mongodb/chj_db/auth/keyfile.key
 authorization: enabled

replication:
 replSetName: shard1
sharding:
 clusterRole: shardsvr

4、生產(chǎn)key認(rèn)證文件

echo "chj123456" >/chj/data/mongodb/chj_db/auth/keyfile.key
#設(shè)置文件的權(quán)限為400，不然服務(wù)無(wú)法啟動(dòng)
chmod 400 /chj/data/mongodb/chj_db/auth/keyfile.key

三、集群初始化

1、啟動(dòng) config server 服務(wù)

/chj/data/mongodb/chj_db/bin/mongod -f /chj/data/mongodb/chj_db/conf/config.conf

2、初始化config server集群

#登錄其中一個(gè)config server節(jié)點(diǎn)
/chj/data/mongodb/chj_db/bin/mongo --port 27100
#配置集群
config = { _id:"repl_configsvr",members:[ {_id:0,host:"172.21.244.101:27100"}, {_id:1,host:"172.21.244.102:27100"}, {_id:2,host:"172.21.244.94:27100"}] }
#初始化集群
rs.initiate(config)
PS：
結(jié)果輸出如下，說(shuō)明集群初始化成功，可以通過(guò)rs.status()命令查看集群狀態(tài)
{
    "ok" : 1,
    "$gleStats" : {
        "lastOpTime" : Timestamp(1557538260, 1),
        "electionId" : ObjectId("000000000000000000000000")
    },
    "lastCommittedOpTime" : Timestamp(0, 0)
}

3、啟動(dòng)存儲(chǔ)節(jié)點(diǎn)服務(wù)

/chj/data/mongodb/chj_db/bin/mongod -f /chj/data/mongodb/chj_db/conf/shard1.conf

4、初始化存儲(chǔ)集群

#登錄你希望是主節(jié)點(diǎn)的服務(wù)器
/chj/data/mongodb/chj_db/bin/mongo --port 27101
#配置集群
config = { _id:"shard1",members:[ {_id:0,host:"172.21.244.101:27101"}, {_id:1,host:"172.21.244.102:27101"},{_id:2,host:"172.21.244.94:27101",arbiterOnly:true}] }
#初始化集群
rs.initiate(config)
PS：
結(jié)果輸出如下，說(shuō)明集群初始化成功，可以通過(guò)rs.status()命令查看集群狀態(tài)
{ "ok" : 1 }

5、添加存儲(chǔ)集群的管理賬號(hào)

登錄主節(jié)點(diǎn)

/chj/data/mongodb/chj_db/bin/mongo --port 27101
use admin
db.createUser(
{
user: "root",
pwd: "123456",
roles: [ { role: "root", db: "admin" } ]
}
)

6、啟動(dòng)mongos 服務(wù)

/chj/data/mongodb/chj_db/bin/mongos -f /chj/data/mongodb/chj_db/conf/mongos.conf

7、添加config server的管理賬號(hào)

登錄任意一個(gè)mongos節(jié)點(diǎn)

/chj/data/mongodb/chj_db/bin/mongo --port 27000
use admin
db.createUser(
{
user: "root",
pwd: "123456",
roles: [ { role: "root", db: "admin" } ]
}
)

8、把存儲(chǔ)節(jié)點(diǎn)添加到mongos

登錄任意一個(gè)mongos節(jié)點(diǎn)（如果是在上一步的窗口，需要退出重新登錄）

/chj/data/mongodb/chj_db/bin/mongo --port 27000
use admin
db.auth('root','123456')
#添加分片
sh.addShard('shard1/172.21.244.101:27101,172.21.244.102:27101,172.21.244.94:27101')
#查看分片狀態(tài)
sh.status()

四、交付業(yè)務(wù)方

1、建立應(yīng)用賬號(hào)

登錄任意一個(gè)mongos節(jié)點(diǎn)
/chj/data/mongodb/chj_db/bin/mongo --port 27000
use admin
db.auth('root','123456')
#切到業(yè)務(wù)數(shù)據(jù)庫(kù)
use chj_db
#建立讀寫(xiě)賬號(hào)
db.createUser(
{
  user: "chj_db_rw",
  pwd: "123456",
  roles: [
   { role: "readWrite", db: "chj_db" },
   { role: "dbOwner", db: "chj_db" }
  ]
}
)
#建立只讀賬號(hào)(根據(jù)業(yè)務(wù)需求確認(rèn)是否需要)
db.createUser(
{
user: "chj_db_r",
pwd: "123456",
roles: [ { role: "read", db: "chj_db" } ]
}
)

2、交付開(kāi)發(fā)人員信息

連接地址：172.21.244.101:27000，172.21.244.102:27000，172.21.244.94:27000
庫(kù)名：chj_db
賬號(hào)：chj_db_rw
密碼：123456

五、數(shù)據(jù)庫(kù)啟用分片

如果后期業(yè)務(wù)量大，需要開(kāi)啟分片，配置如下

#指定需要分片的數(shù)據(jù)庫(kù)
mongos> sh.enableSharding("chj_db") 
{
    "ok" : 1,
    "operationTime" : Timestamp(1557546835, 3),
    "$clusterTime" : {
        "clusterTime" : Timestamp(1557546835, 3),
        "signature" : {
            "hash" : BinData(0,"bkrrr8Kxrr9j9udrDc/hURHld38="),
            "keyId" : NumberLong("6689575940508352541")
        }
    }
}
#在chj_db數(shù)據(jù)庫(kù)和users集合中創(chuàng)建了name和age為升序的片鍵
mongos> sh.shardCollection("chj_db.users",{name:1,age:1}) 
{
    "collectionsharded" : "chj_db.users",
    "collectionUUID" : UUID("59c0b99f-efff-4132-b489-f6c7e3d98f42"),
    "ok" : 1,
    "operationTime" : Timestamp(1557546861, 12),
    "$clusterTime" : {
        "clusterTime" : Timestamp(1557546861, 12),
        "signature" : {
            "hash" : BinData(0,"UBB1A/YODnmXwG5eAhgNLcKVzug="),
            "keyId" : NumberLong("6689575940508352541")
        }
    }
}
#查看分片情況
mongos> sh.status() 
--- Sharding Status ---
 sharding version: {
    "_id" : 1,
    "minCompatibleVersion" : 5,

        chj_db.users
            shard key: { "name" : 1, "age" : 1 }
            unique: false
            balancing: true
            chunks:
                shard1 1
            { "name" : { "$minKey" : 1 }, "age" : { "$minKey" : 1 } } -->> { "name" : { "$maxKey" : 1 }, "age" : { "$maxKey" : 1 } } on : shard1 Timestamp(1, 0)
    { "_id" : "config", "primary" : "config", "partitioned" : true }
        config.system.sessions
            shard key: { "_id" : 1 }
            unique: false
            balancing: true
            chunks:
                shard1 1
            { "_id" : { "$minKey" : 1 } } -->> { "_id" : { "$maxKey" : 1 } } on : shard1 Timestamp(1, 0)

以上就是本文的全部?jī)?nèi)容，希望對(duì)大家的學(xué)習(xí)有所幫助，也希望大家多多支持腳本之家。
