一.Shard节点配置过程 1. 目录创建：

mkdir -p /mongodb/38021/conf /mongodb/38021/log /mongodb/38021/data

mkdir -p /mongodb/38022/conf /mongodb/38022/log /mongodb/38022/data

mkdir -p /mongodb/38023/conf /mongodb/38023/log /mongodb/38023/data

mkdir -p /mongodb/38024/conf /mongodb/38024/log /mongodb/38024/data

mkdir -p /mongodb/38025/conf /mongodb/38025/log /mongodb/38025/data

mkdir -p /mongodb/38026/conf /mongodb/38026/log /mongodb/38026/data

2. 修改配置文件：

第一组复制集搭建：21-23（1主 1从 1Arb）

cat > /mongodb/38021/conf/mongodb.conf <<EOF

systemLog:

destination: file

path: /mongodb/38021/log/mongodb.log

logAppend: true

storage:

journal:

    enabled: true

dbPath: /mongodb/38021/data

directoryPerDB: true

#engine: wiredTiger

wiredTiger:

    engineConfig:

      cacheSizeGB: 1

      directoryForIndexes: true

    collectionConfig:

      blockCompressor: zlib

    indexConfig:

      prefixCompression: true

net:

bindIp: 10.0.0.51,127.0.0.1

port: 38021

replication:

oplogSizeMB: 2048

replSetName: sh1

sharding:

clusterRole: shardsvr

processManagement:

fork: true

EOF

\cp /mongodb/38021/conf/mongodb.conf /mongodb/38022/conf/

\cp /mongodb/38021/conf/mongodb.conf /mongodb/38023/conf/ sed ‘s#38021#38022#g‘ /mongodb/38022/conf/mongodb.conf -i

sed ‘s#38021#38023#g‘ /mongodb/38023/conf/mongodb.conf -i

第二组节点：24-26(1主1从1Arb)

cat > /mongodb/38024/conf/mongodb.conf <<EOF

systemLog:

destination: file

path: /mongodb/38024/log/mongodb.log

logAppend: true

storage:

journal:

    enabled: true

dbPath: /mongodb/38024/data

directoryPerDB: true

wiredTiger:

    engineConfig:

      cacheSizeGB: 1

      directoryForIndexes: true

    collectionConfig:

      blockCompressor: zlib

    indexConfig:

      prefixCompression: true

net:

bindIp: 10.0.0.51,127.0.0.1

port: 38024

replication:

oplogSizeMB: 2048

replSetName: sh2

sharding:

clusterRole: shardsvr

processManagement:

fork: true

EOF \cp /mongodb/38024/conf/mongodb.conf /mongodb/38025/conf/

\cp /mongodb/38024/conf/mongodb.conf /mongodb/38026/conf/

sed ‘s#38024#38025#g‘ /mongodb/38025/conf/mongodb.conf -i

sed ‘s#38024#38026#g‘ /mongodb/38026/conf/mongodb.conf -i

3.启动所有节点，并搭建复制集

mongod -f /mongodb/38021/conf/mongodb.conf

mongod -f /mongodb/38022/conf/mongodb.conf

mongod -f /mongodb/38023/conf/mongodb.conf

mongod -f /mongodb/38024/conf/mongodb.conf

mongod -f /mongodb/38025/conf/mongodb.conf

mongod -f /mongodb/38026/conf/mongodb.conf

ps -ef |grep mongod mongo --port 38021

use admin

config = {_id: ‘sh1‘, members: [

                          {_id: 0, host: ‘10.0.0.51:38021‘},

                          {_id: 1, host: ‘10.0.0.51:38022‘},

                          {_id: 2, host: ‘10.0.0.51:38023‘,"arbiterOnly":true}]

           } rs.initiate(config)

mongo --port 38024

use admin

config = {_id: ‘sh2‘, members: [

                          {_id: 0, host: ‘10.0.0.51:38024‘},

                          {_id: 1, host: ‘10.0.0.51:38025‘},

                          {_id: 2, host: ‘10.0.0.51:38026‘,"arbiterOnly":true}]

           }

rs.initiate(config) 4. config节点配置

5. 目录创建

mkdir -p /mongodb/38018/conf /mongodb/38018/log /mongodb/38018/data

mkdir -p /mongodb/38019/conf /mongodb/38019/log /mongodb/38019/data

mkdir -p /mongodb/38020/conf /mongodb/38020/log /mongodb/38020/data

6.修改配置文件：

cat > /mongodb/38018/conf/mongodb.conf <<EOF

systemLog:

destination: file

path: /mongodb/38018/log/mongodb.conf

logAppend: true

storage:

journal:

    enabled: true

dbPath: /mongodb/38018/data

directoryPerDB: true

#engine: wiredTiger

wiredTiger:

    engineConfig:

      cacheSizeGB: 1

      directoryForIndexes: true

    collectionConfig:

      blockCompressor: zlib

    indexConfig:

      prefixCompression: true

net:

bindIp: 10.0.0.51,127.0.0.1

port: 38018

replication:

oplogSizeMB: 2048

replSetName: configReplSet

sharding:

clusterRole: configsvr

processManagement:

fork: true

EOF \cp /mongodb/38018/conf/mongodb.conf /mongodb/38019/conf/

\cp /mongodb/38018/conf/mongodb.conf /mongodb/38020/conf/

sed ‘s#38018#38019#g‘ /mongodb/38019/conf/mongodb.conf -i

sed ‘s#38018#38020#g‘ /mongodb/38020/conf/mongodb.conf -i

7.启动节点，并配置复制集

mongod -f /mongodb/38018/conf/mongodb.conf

mongod -f /mongodb/38019/conf/mongodb.conf

mongod -f /mongodb/38020/conf/mongodb.conf mongo --port 38018

use admin

config = {_id: ‘configReplSet‘, members: [

                          {_id: 0, host: ‘10.0.0.51:38018‘},

                          {_id: 1, host: ‘10.0.0.51:38019‘},

                          {_id: 2, host: ‘10.0.0.51:38020‘}]

           }

rs.initiate(config)

注：configserver 可以是一个节点，官方建议复制集。configserver不能有arbiter。

新版本中，要求必须是复制集。

注：mongodb 3.4之后，虽然要求config server为replica set，但是不支持arbiter 8. mongos节点配置：

9.创建目录：

mkdir -p /mongodb/38017/conf /mongodb/38017/log

10.配置文件：

cat > /mongodb/38017/conf/mongos.conf <<EOF

systemLog:

destination: file

path: /mongodb/38017/log/mongos.log

logAppend: true

net:

bindIp: 10.0.0.51,127.0.0.1

port: 38017

sharding:

configDB: configReplSet/10.0.0.51:38018,10.0.0.51:38019,10.0.0.51:38020

processManagement:

fork: true

EOF

11.启动mongos

mongos -f /mongodb/38017/conf/mongos.conf

12. 分片集群添加节点

连接到其中一个mongos（10.0.0.51），做以下配置

（1）连接到mongs的admin数据库

# su - mongod

$ mongo 10.0.0.51:38017/admin

（2）添加分片

db.runCommand( { addshard : "sh1/10.0.0.51:38021,10.0.0.51:38022,10.0.0.51:38023",name:"shard1"} )

db.runCommand( { addshard : "sh2/10.0.0.51:38024,10.0.0.51:38025,10.0.0.51:38026",name:"shard2"} )

（3）列出分片

mongos> db.runCommand( { listshards : 1 } )

（4）整体状态查看

mongos> sh.status();
