centos下搭建mongodb集群mongodbcentos安装前先同步服务器时间：a.yum install ntpb.ntpdate 210.72.145.44配置总览：3个分片sharding每一个分片由3个节点构成1主2备的Replica Sets3个配置节点Configsever1个路由节点Mongos步骤：首先安装mongodb：将其解压到/usr，再重命名为mongodb，路径为/ usr /mongodb1. 创建分片：server A:mkdir -p /data/a/r0mkdir -p /data/b/r0mkdir -p /data/c/r0mkdir -p /data/logs/amkdir -p /data/logs/bmkdir -p /data/logs/cmkdir -p /data/configServer/r0mkdir -p /data/logs/configServermkdir -p /data/logs/serverlogs./mongod -logpath /data/logs/a/r0.log -logappend -dbpath /data/a/r0 -port 10000 -shardsvr -replSet setA -rest -oplogSize 64 -forkserverB serverC 执行同上命令。2.初始化复制集setA：./mongo 192.168.1.115:10000/adminconfig=_id: setA, members:_id: 0,host:192.168.1.115:10000,_id:1,host:192.168.1.116:10000,_id:2,host:192.168.1.117:10000rs.initiate(config);3.初始化复制集setB:./mongod -logpath /data/logs/b/r0.log -logappend -dbpath /data/b/r0 -port 20000 -shardsvr -replSet setB -rest -oplogSize 64 -fork./mongo 192.168.1.116:20000/adminconfig=_id: setB, members:_id: 0,host:192.168.1.115:20000,_id:1,host:192.168.1.116:20000,_id:2,host:192.168.1.117:20000rs.initiate(config);4.初始化复制集setC:./mongod -logpath /data/logs/c/r0.log -logappend -dbpath /data/c/r0 -port 30000 -shardsvr -replSet setC -rest -oplogSize 64 -fork./mongo 192.168.1.117:30000/adminconfig=_id: setC, members:_id: 0,host:192.168.1.115:30000,_id:1,host:192.168.1.116:30000,_id:2,host:192.168.1.117:30000rs.initiate(config);5.配置config Server:115 116 117上执行./mongod -configsvr -logpath /data/logs/configServer/r0.log -logappend -dbpath /data/configServer/r0 -port 40000 -shardsvr -fork6.启动路由节点：115 上执行：./mongos -configdb 192.168.1.115:40000,192.168.1.116:40000,192.168.1.116:40000 -logpath /data/logs/serverlogs/mongos.log -logappend -port 50000 -fork7.配置分片115 上执行：./mongo 127.0.0.1:50000use admindb.runCommand(addshard:setA/192.168.1.115:10000,192.168.1.116:10000,192.168.1.117:10000,name:ShardSetA)db.runCommand(addshard:setB/192.168.1.115:20000,192.168.1.116:20000,192.168.1.117:20000,name:ShardSetB)db.runCommand(addshard:setC/192.168.1.115:30000,192.168.1.116:30000,192.168.1.117:30000,name:ShardSetC)printShardingStatus();数据库连接时通过192.168.1.115 端口连接50000ES连接river配置时，不能通过路由端口。 可通过10000或者200001.设置分片存储的DB,如设置test库分片存储。db.runCommand( enablesharding:test )2
