mongodb 分片集群安装搭建测试
关于什么是mongodb分片集群，这些这里就不介绍，网上有很多的说明。
由于是测试资源有限，于是就把所有的节点都搭建在一台服务器上面了，实际的生产环境最好config/mongos/shard都分开安装到不同的机器上，这里搭建了12个节点的分片集群；将端口区分开，创建3个mongs节点，3节点的config-server副本集，3个2节点的shard副本集。使用版本：4.0.18
| 主机 |
端口 |
角色 |
副本集/分片类型 |
| 172.100.1.35 |
27017,37017,47017 |
mongos |
— |
| 172.100.1.35 |
27019,37019,47019 |
config server |
cs0/configsvr |
| 172.100.1.35 |
27018,37018,47018 |
shardA |
shardA/shardsvr |
| 172.100.1.35 |
27016,37016,47016 |
shardB |
shardB/shardsvr |
话不多说直接开搞:
下面就是此次测试环境需要的mongodb节点

drwxr-xr-x 6 root root 199 Jun 2 14:22 mongodb_shardB_3首先对configsvr进行配置
分别在 mongodb_config_27019，mongodb_config_37019，mongodb_config_47019下创建对应的配置文件，这里我的配置文件分别为:mogondb_config_27019.conf，mogondb_config_37019.conf，mogondb_config_47019.conf
编辑配置文件，这里就以添加mongodb_config_27019几点为例，添加以下内容:
[root@cpe-172-100-1-35 mongodb_config_27019]# cat mogondb_config_27019.conf
systemLog:
traceAllExceptions: false
path: /webapp/jsunicom/mongodb_config_27019/logs/mongod.log
logAppend: true
destination: file
timeStampFormat: ctime
processManagement:
fork: true
pidFilePath: /webapp/jsunicom/mongodb_config_27019/tmp/mongod.pid
net:
port: 27019
bindIp: 172.100.1.35
maxIncomingConnections: 20000
storage:
dbPath: /webapp/jsunicom/mongodb_config_27019/data
directoryPerDB: true
wiredTiger:
engineConfig:
cacheSizeGB: 1
directoryForIndexes: true
operationProfiling:
slowOpThresholdMs: 1000
replication:
oplogSizeMB: 2048
replSetName: cs0
sharding:
clusterRole: configsvr
注意：其余2个节点除了端口号以及路径和上面的不一样，其余完全一致。
配置好之后，分别启动这3个config节点
[root@cpe-172-100-1-35 ~]# /webapp/jsunicom/mongodb_config_27019/bin/mongod -f /webapp/jsunicom/mongodb_config_27019/mogondb_config_27019.conf
[root@cpe-172-100-1-35 ~]# /webapp/jsunicom/mongodb_config_37019/bin/mongod -f /webapp/jsunicom/mongodb_config_37019/mogondb_config_37019.conf
[root@cpe-172-100-1-35 ~]# /webapp/jsunicom/mongodb_config_47019/bin/mongod -f /webapp/jsunicom/mongodb_config_47019/mogondb_config_47019.conf启动之后，随便登录上面3个config节点中的一个进行初始化
[root@cpe-172-100-1-35 ~]# /webapp/jsunicom/mongodb_config_27019/bin/mongo --host 172.100.1.35 --port 27019
执行以下命令
use admin
rs.initiate(
{
_id: "cs0",
configsvr: true,
members: [
{ _id : 0, host : "172.100.1.35:27019" },
{ _id : 1, host : "172.100.1.35:37019" },
{ _id : 2, host : "172.100.1.35:47019" }
]
}
)
执行成功之后，一定要用以下命令来查看初始化是否正常
rs.status()
其中health：1 代表初始化成功到此config配置结束
下面对shardA,shardB配置：
shardA配置:
分别在mongodb_shardA_1，mongodb_shardA_2，mongodb_shardA_3下创建对应的配置文件
我这里分别为：mongodb_shardA_1.conf，mongodb_shardA_2.conf ，mongodb_shardA_3.conf
编辑配置文件，这里还是以mongodb_shardA_1.conf为例，添加如下内容：
[root@cpe-172-100-1-35 mongodb_shardA_1]# cat mongodb_shardA_1.conf
systemLog:
traceAllExceptions: false
path: /webapp/jsunicom/mongodb_shardA_1/logs/mongod.log
logAppend: true
destination: file
timeStampFormat: ctime
processManagement:
fork: true
pidFilePath: /webapp/jsunicom/mongodb_shardA_1/tmp/mongod.pid
net:
port: 27018
bindIp: 172.100.1.35
maxIncomingConnections: 20000
storage:
dbPath: /webapp/jsunicom/mongodb_shardA_1/data
directoryPerDB: true
wiredTiger:
engineConfig:
cacheSizeGB: 1
directoryForIndexes: true
operationProfiling:
slowOpThresholdMs: 1000
replication:
oplogSizeMB: 3072
replSetName: shardA
sharding:
clusterRole: shardsvr
setParameter:
connPoolMaxShardedInUseConnsPerHost: 100
shardedConnPoolIdleTimeoutMinutes: 10
connPoolMaxInUseConnsPerHost: 100
globalConnPoolIdleTimeoutMinutes: 10
maxIndexBuildMemoryUsageMegabytes: 2048备注：其余2个节点配置除了端口号以及路径不一致以外，其余完全和上面一致
shardB配置:
其实shardB配置和shardA完全一样，只要注意端口以及路径就行了
同样分别在mongodb_shardB_1，mongodb_shardB_2，mongodb_shardB_3下创建对应的配置文件
我这里分别为：mongodb_shardB_1.conf，mongodb_shardB_2.conf ，mongodb_shardB_3.conf
编辑配置文件，这里还是以mongodb_shardB_1.conf为例，添加如下内容：
[root@cpe-172-100-1-35 mongodb_shardB_1]# cat mongodb_shardB_1.conf
systemLog:
traceAllExceptions: false
path: /webapp/jsunicom/mongodb_shardB_1/logs/mongod.log
logAppend: true
destination: file
timeStampFormat: ctime
processManagement:
fork: true
pidFilePath: /webapp/jsunicom/mongodb_shardB_1/tmp/mongod.pid
net:
port: 27016
bindIp: 172.100.1.35
maxIncomingConnections: 20000
storage:
dbPath: /webapp/jsunicom/mongodb_shardB_1/data
directoryPerDB: true
wiredTiger:
engineConfig:
cacheSizeGB: 1
directoryForIndexes: true
operationProfiling:
slowOpThresholdMs: 1000
replication:
oplogSizeMB: 3072
replSetName: shardB
sharding:
clusterRole: shardsvr
setParameter:
connPoolMaxShardedInUseConnsPerHost: 100
shardedConnPoolIdleTimeoutMinutes: 10
connPoolMaxInUseConnsPerHost: 100
globalConnPoolIdleTimeoutMinutes: 10
maxIndexBuildMemoryUsageMegabytes: 2048备注：其余2个节点配置除了端口号以及路径不一致以外，其余完全和上面一致
配置好之后，那就把上面的shardA3个节点以及shardB三个节点分别起起来。
[root@cpe-172-100-1-35 ~]# /webapp/jsunicom/mongodb_shardA_1/bin/mongod -f /webapp/jsunicom/mongodb_shardA_1/mongodb_shardA_1.conf
[root@cpe-172-100-1-35 ~]# /webapp/jsunicom/mongodb_shardA_2/bin/mongod -f /webapp/jsunicom/mongodb_shardA_2/mongodb_shardA_2.conf
[root@cpe-172-100-1-35 ~]# /webapp/jsunicom/mongodb_shardA_3/bin/mongod -f /webapp/jsunicom/mongodb_shardA_3/mongodb_shardA_3.conf
[root@cpe-172-100-1-35 ~]# /webapp/jsunicom/mongodb_shardB_1/bin/mongod -f /webapp/jsunicom/mongodb_shardB_1/mongodb_shardB_1.conf
[root@cpe-172-100-1-35 ~]# /webapp/jsunicom/mongodb_shardB_2/bin/mongod -f /webapp/jsunicom/mongodb_shardB_2/mongodb_shardB_2.conf
[root@cpe-172-100-1-35 ~]# /webapp/jsunicom/mongodb_shardB_3/bin/mongod -f /webapp/jsunicom/mongodb_shardB_3/mongodb_shardB_3.conf然后分别初始化话replicat 配置
shardA:
随便登录shardA3个节点中的其中一个节点即可：
[root@cpe-172-100-1-35 ~]# /webapp/jsunicom/mongodb_config_27019/bin/mongo --host 172.100.1.35 --port 27018
登录之后执行以下命令
use admin
rs.initiate(
{
_id : "shardA",
members: [
{ _id : 0, host : "172.100.1.35:27018" },
{ _id : 1, host : "172.100.1.35:37018" },
{ _id : 2, host : "172.100.1.35:47018",arbiterOnly: true }
]
}
)
同样也要用下面命令去查看初始化是否成功
rs.status()
其中health：1 代表初始化成功shardB:
随便登录shardB3个节点中的其中一个节点即可：
[root@cpe-172-100-1-35 ~]# /webapp/jsunicom/mongodb_config_27019/bin/mongo --host 172.100.1.35 --port 27016
登录成功以后执行以下命令进行初始化
use admin
rs.initiate(
{
_id : "shardB",
members: [
{ _id : 0, host : "172.100.1.35:27016" },
{ _id : 1, host : "172.100.1.35:37016" },
{ _id : 2, host : "172.100.1.35:47016",arbiterOnly: true }
]
}
)
同样需要使用rs.status()命令查看是否执行成功
其中health ：1 代表初始化成功至此shardA，shardB分片配置到此结束
最后配置mongos
这里mongos也做了3个节点，
分别在mongodb_mongos1，mongodb_mongos2，mongodb_mongos3下配置mongodb_mongos1.conf，mongodb_mongos2.conf，mongodb_mongos3.conf
编辑配置文件，这里同样以mongodb_mongos1.conf为例，添加如下内容:
[root@cpe-172-100-1-35 mongodb_mongos1]# cat mongodb_mongos1.conf
systemLog:
traceAllExceptions: false
path: /webapp/jsunicom/mongodb_mongos1/logs/mongos.log
logAppend: true
destination: file
timeStampFormat: ctime
processManagement:
fork: true
pidFilePath: /webapp/jsunicom/mongodb_mongos1/tmp/mongos.pid

port: 27017
bindIp: 172.100.1.35
maxIncomingConnections: 20000
operationProfiling:
slowOpThresholdMs: 1000
replication:
localPingThresholdMs: 300
sharding:
configDB: cs0/172.100.1.35:27019,172.100.1.35:37019,172.100.1.35:47019
setParameter:
connPoolMaxShardedInUseConnsPerHost: 100
shardedConnPoolIdleTimeoutMinutes: 10
connPoolMaxInUseConnsPerHost: 100
globalConnPoolIdleTimeoutMinutes: 10备注：其余2个节点配置除了端口号以及路径和上面不一样之外，其余完全一致
上面配置文件配置好之后，分别启动这3个节点：
[root@cpe-172-100-1-35 ~]# /webapp/jsunicom/mongodb_mongos1/bin/mongos -f /webapp/jsunicom/mongodb_mongos1/mongodb_mongos1.conf
[root@cpe-172-100-1-35 ~]# /webapp/jsunicom/mongodb_mongos2/bin/mongos -f /webapp/jsunicom/mongodb_mongos2/mongodb_mongos2.conf
[root@cpe-172-100-1-35 ~]# /webapp/jsunicom/mongodb_mongos3/bin/mongos -f /webapp/jsunicom/mongodb_mongos3/mongodb_mongos3.conf随便登录上面3个节点中的其中一个，添加replicat 到sharding中
[root@cpe-172-100-1-35 ~]# /webapp/jsunicom/mongodb_config_27019/bin/mongo --host 172.100.1.35 --port 27017
登录之后执行如下命令:
use admin
sh.addShard("shardA/172.100.1.35:27018,172.100.1.35:37018,172.100.1.35:47018")
sh.addShard("shardA/172.100.1.35:27018,172.100.1.35:37016,172.100.1.35:47016")
执行完之后使用rs.status()命令查看状态
mongos> sh.status()

下面所有的操作都是在mongos其中一个节点上执行的
启动sharding库:
sh.enableSharding("yuhuashi")
创建分片集合：
sh.shardCollection("yuhuashi.user",{"name" : 1}) #ranged 分片
sh.shardCollection("yuhuashi.user", { "task_id" : "hashed" } ) #hash分片
我这里使用了hashed分片
mongos> sh.shardCollection("yuhuashi.user", { "task_id" : "hashed" } )
{
"collectionsharded" : "yuhuashi.user",
"collectionUUID" : UUID("43d3cce7-0225-4dcc-8b7e-aecc7b3932b6"),
"ok" : 1,

"signature" : {

}
}
}可以使用sh.status()来查看状态

mongos> db.user.find().count()
0
mongos> for(i=1;i<=10000;i++){db.user.insert({"task_id":i,"name":"shiyu"+i,"age":i})}
WriteResult({ "nInserted" : 1 })
分别登录shardA和shardB分片查看
shardA:PRIMARY> use yuhuashi
switched to db yuhuashi
shardA:PRIMARY> db.user.find().count()
7521
shardA:PRIMARY>
shardB:PRIMARY> use yuhuashi
switched to db yuhuashi
shardB:PRIMARY> db.user.find().count()

GAME OVER!
