mongodb叢集 組件：mongos：請求分發config server 設定管理員shard 分區資料服務器 三台機器192.168.174.128192.168.174.129192.168.174.130伺服器規劃  連接埠分配： mongos：20000config：21000shard1：27001shard2：27002shard3：27003 伺服器需要同步時間，否則測試不通過 128機器操作 1、下載官網:https://www.mongodb.com/download-center#community 2、解壓    tar -xf mongodb-linux-x86_64-rhel70-3.6.5.tgz && mv mongodb-linux-x86_64-rhel70-3.6.5 /usr/local/mongodb 3、加環境變數，方便操作(3台機器)    vim /etc/profile        export PATH=$PATH:/usr/local/mongodb/bin    source /etc/profile 4、建立所需目錄     mkdir -p /usr/local/mongodb/{conf,config/{data,log},shard1/{data,log},shard2/{data,log},shard3/{data,log},mongos/log} 5、編寫設定檔config.conf、shard1.conf、shard2.conf、shard3.conf、mongos.conf ====================================================================================vim

/usr/local/mongodb 192.168.174.130:/usr/local/mongodb    scp -r /usr/local/mongodb 192.168.174.131:/usr/local/mongodb     **注意：130和131節點，設定檔中的bindIp需要修改為對應的IP 7、建立使用者，授權（三台機器）    useradd mongod    chown -R mongod:mongod /usr/local/mongodb/ ============================================================================8、啟動設定管理員（3台）    mongod -f /usr/local/mongodb/conf/config.conf 9、初始化複本集（登陸任意一個執行個體即可）    #串連        mongo 192.168.174.128:21000    #初始化複本集        rs.initiate(  {    _id: "configs",    configsvr: true,    members: [      { _id : 0, host : "192.168.174.128:21000" },      { _id : 1, host : "192.168.174.130:21000" },      { _id : 2, host : "192.168.174.131:21000" }    ]  })     #查看狀態    rs.status();==============================================================================10、啟動shard1、shard2、shard3（3台）    mongod -f /usr/local/mongodb/conf/shard1.conf    mongod -f /usr/local/mongodb/conf/shard2.conf    mongod -f /usr/local/mongodb/conf/shard3.conf 11、初始化複本集（在一台執行即可）     #串連        mongo 192.168.174.130:27001    #初始化複本集        rs.initiate(  {    _id : "shard1",    members: [      { _id : 0, host : "192.168.174.128:27001",priority:2},      { _id : 1, host : "192.168.174.130:27001",priority:1},      { _id : 2, host : "192.168.174.131:27001",arbiterOnly: true}    ]  })    #查看狀態    rs.status();     #串連        mongo 192.168.174.131:27002    #初始化複本集        rs.initiate(  {    _id : "shard2",    members: [      { _id : 0, host : "192.168.174.128:27002",arbiterOnly: true},      { _id : 1, host : "192.168.174.130:27002",priority:2},      { _id : 2, host : "192.168.174.131:27002",priority:1}    ]  })    #查看狀態    rs.status();     #串連        mongo 192.168.174.128:27003    #初始化複本集        rs.initiate(  {    _id : "shard3",    members: [      { _id : 0, host : "192.168.174.128:27003",priority:1},      { _id : 1, host : "192.168.174.130:27003",arbiterOnly: true},      { _id : 2, host : "192.168.174.131:27003",priority:2}    ]  })     #查看狀態    rs.status();===============================================================================12、啟動mongos（3台）    mongos -f /usr/local/mongodb/conf/mongos.conf 13、啟用分區（登陸任意一個執行個體）        mongo 192.168.174.128:20000                use  admin                sh.addShard("shard1/192.168.174.128:27001,192.168.174.130:27001,192.168.174.130:27001");        sh.addShard("shard2/192.168.174.128:27002,192.168.174.130:27002,192.168.174.130:27002");        sh.addShard("shard3/192.168.174.128:27003,192.168.174.130:27003,192.168.174.130:27003");            #查看叢集狀態        sh.status(); =============================================================================== 14、測試                設定chunk大小            use config            db.settings.save({ "_id" : "chunksize", "value" : 1 })            #為方便測試設為1M，否則需要插入大量資料才會分區儲存         登陸            mongo 192.168.127.128:20000        指定testdb分區生效            use admin;            db.runCommand({ enablesharding :"testdb"});        指定需要分區的集合和片鍵            db.runCommand({ shardcollection : "testdb.table1",key : {id: 1} });                use testdb;        插入資料            for (var i = 1; i <= 10000; i++) db.table1.save({id:i,"test1":"testval1"});        查看是分區情況               db.table1.stats();           可以看到資料分到3個分區，各自分區數量為： shard1 “count” : 42183，shard2 “count” : 38937，shard3 “count” : 18880。已經成功了！ 啟動關閉     mongodb的啟動順序是，先啟動設定管理員，在啟動分區，最後啟動mongos.         mongod -f /usr/local/mongodb/conf/config.conf        mongod -f /usr/local/mongodb/conf/shard1.conf        mongod -f /usr/local/mongodb/conf/shard2.conf        mongod -f /usr/local/mongodb/conf/shard3.conf        mongos -f /usr/local/mongodb/conf/mongos.conf 關閉時，直接killall殺掉所有進程（測試使用）     pkill mongo
