mongodb 分片集群+副本集搭建

节点规划：
mongos：
28015、28016、28017 


configserver:
28018、28019、28020（复制集）


mongod:
28021、28022、28023（复制集）

28024、28025、28026（复制集）



创建目录
for i in  15 16 17 18 19 20 21 22 23 24 25 26 
  do 
  mkdir -p /mongodb/280$i/conf  
  mkdir -p /mongodb/280$i/data  
  mkdir -p /mongodb/280$i/log
done
 
 
编辑shard集群配置文件
 
cat > /mongodb/28021/conf/mongod.conf <<'EOF'
systemLog:
  destination: file
  path: /mongodb/28021/log/mongodb.log   
  logAppend: true

复制shard集群配置文件
for i in 22 23 24 25 26  
  do  
   \cp /mongodb/28021/conf/mongod.conf /mongodb/280$i/conf/
done
 

修改配置文件端口
for i in 22 23 24 25 26  
  do 
    sed -i "s#28021#280$i#g" /mongodb/280$i/conf/mongod.conf
done


修改配置文件复制集名称（replSetName）
for i in 24 25 26  
  do 
    sed -i "s#sh1#sh2#g" /mongodb/280$i/conf/mongod.conf
done


启动shard集群
for i in 21 22 23 24 25 26
  do  
    mongod -f /mongodb/280$i/conf/mongod.conf 
done


配置复制集
mongo --host 127.0.0.1 --port 28021 admin

config = {_id: 'sh1', members: [
    {_id: 0, host: '127.0.0.1:28021'},
    {_id: 1, host: '127.0.0.1:28022'},
    {_id: 2, host: '127.0.0.1:28023'}]
}  

rs.initiate(config) 
 

配置复制集
mongo --host 127.0.0.1 --port 28024 admin
 
config = {_id: 'sh2', members: [
    {_id: 0, host: '127.0.0.1:28024'},
    {_id: 1, host: '127.0.0.1:28025'},
    {_id: 2, host: '127.0.0.1:28026'}]
}

rs.initiate(config)
 
 
config集群配置
 
创建主节点配置文件
 
cat > /mongodb/28018/conf/mongod.conf <<'EOF'
systemLog:
  destination: file
  path: /mongodb/28018/log/mongodb.conf
  logAppend: true
storage:
  journal:
    enabled: true
  dbPath: /mongodb/28018/data
  directoryPerDB: true
  #engine: wiredTiger
  wiredTiger:
    engineConfig:
      cacheSizeGB: 1
      directoryForIndexes: true
    collectionConfig:
      blockCompressor: zlib
    indexConfig:
      prefixCompression: true
net:
  bindIp: 127.0.0.1
  port: 28018
replication:
  oplogSizeMB: 2048
  replSetName: configReplSet
sharding:
  clusterRole: configsvr
processManagement: 
  fork: true
EOF

 
将配置文件分发到从节点
for i in 19 20 
  do  
   \cp /mongodb/28018/conf/mongod.conf /mongodb/280$i/conf/
done
 
 
修改配置文件端口信息
for i in 19 20  
  do 
    sed -i "s#28018#280$i#g" /mongodb/280$i/conf/mongod.conf
done
 
 
启动configserver集群
for i in 18 19 20
  do  
    mongod -f /mongodb/280$i/conf/mongod.conf 
done
 
 
配置configserver复制集
mongo --host 127.0.0.1 --port 28018 admin

 
配置复制集信息
config = {_id: 'configReplSet', members: [
    {_id: 0, host: '127.0.0.1:28018'},
    {_id: 1, host: '127.0.0.1:28019'},
    {_id: 2, host: '127.0.0.1:28020'}]
}
 
 
rs.initiate(config)   

 
 
 
mongos节点配置

创建配置文件
cat > /mongodb/28017/conf/mongos.conf <<'EOF'
systemLog:
  destination: file
  path: /mongodb/28017/log/mongos.log
  logAppend: true
net:

sharding:
  configDB: configReplSet/127.0.0.1:28108,127.0.0.1:28019,127.0.0.1:28020
processManagement: 
  fork: true
EOF
 

复制配置文件
for i in 15 16  
  do  
   \cp /mongodb/28017/conf/mongos.conf /mongodb/280$i/conf/
done


修改配置文件端口信息
for i in 15 16  
  do 
    sed -i "s#28017#280$i#g" /mongodb/280$i/conf/mongos.conf
done


启动mongos
for i in 15 16 17
  do  
    mongos -f /mongodb/280$i/conf/mongos.conf
done


登陆到mongos
mongo 127.0.0.1:28017/admin


添加分片节点
db.runCommand( { addshard : "sh1/127.0.0.1:28021,127.0.0.1:28022,127.0.0.1:28023",name:"shard1"} )
db.runCommand( { addshard : "sh2/127.0.0.1:28024,127.0.0.1:28025,127.0.0.1:28026",name:"shard2"} )


列出分片
mongos> use admin
mongos> db.runCommand( { listshards : 1 } )
{
    "shards" : [
        {
            "_id" : "shard1",
            "host" : "sh1/127.0.0.1:28021,127.0.0.1:28022,127.0.0.1:28023",
            "state" : 1
        },
        {
            "_id" : "shard2",
            "host" : "sh2/127.0.0.1:28024,127.0.0.1:28025,127.0.0.1:28026",
            "state" : 1
        }
    ],
    "ok" : 1,
    "operationTime" : Timestamp(1600679934, 1),
    "$clusterTime" : {
        "clusterTime" : Timestamp(1600679934, 1),
        "signature" : {
            "hash" : BinData(0,"AAAAAAAAAAAAAAAAAAAAAAAAAAA="),
            "keyId" : NumberLong(0)
        }
    }
}

或者：
mongos> use config
mongos> db.shards.find()
{ "_id" : "shard1", "host" : "sh1/127.0.0.1:28021,127.0.0.1:28022,127.0.0.1:28023", "state" : 1 }
{ "_id" : "shard2", "host" : "sh2/127.0.0.1:28024,127.0.0.1:28025,127.0.0.1:28026", "state" : 1 }
