【编者按】MongoDB是IT行业非常流行的非关系型数据库（NoSql）。其灵活的数据存储方式深受当下IT从业者的青睐。MongoDB很好的实现了面向对象的思想（OO思想），MongoDB中的每条记录都是一个Document对象。本文介绍了MongoDB在生产环境中实现分片和集群方案的运行实例。一、Mongodb分片与集群拓扑图二、分片与集群部署一、Mongodb安装分别在以上3台服务器上安装mongodb。mongodb安装方法见安装脚本。2.Mongod创建单分片副本集10.68.4.209①创建数据文件夹和日志文件夹mdkir/data/{master,slave,arbiter}mkdir/data/log/mongodb/{master,slave,arbiter}-p②创建配置文件#master.confdbpath=/data/masterlogpath=/data/log/mongodb/master/mongodb.logpidfilepath=/var/run/mongo_master.pid#directoryperdb=truelogappend=truereplSet=policydbport=10002oplogSize=10000fork=truenoprealloc=trueprofile=1slowms=200#slave.confdbpath=/data/slavelogpath=/data/log/mongodb/slave/mongodb.logpidfilepath=/var/run/mongo_slave.pid#directoryperdb=truelogappend=truereplSet=policydbport=10001oplogSize=10000fork=truenoprealloc=trueprofile=1slowms=200#arbiter.confdbpath=/data/arbiterlogpath=/data/log/mongodb/arbiter/mongodb.logpidfilepath=/var/run/mongo_arbiter.pid#directoryperdb=truelogappend=truereplSet=policydbport=10000oplogSize=10000fork=truenoprealloc=trueprofile=1slowms=200③启动mongodb/etc/init.d/mongodb_masterstart/etc/init.d/mongodb_slavestart/etc/init.d/mongodb_arbiterstart④配置主、备、仲裁节点主节点：#/usr/local/mongodb/bin/mongo10.68.4.209:10002MongoDBshellversion:2.4.9connectingto:10.68.4.209:10002/test>useadminswitchedtodbadmin>config={_id:"policydb",members:[{_id:0,host:'10.68.4.209:10002',priority:2},{_id:1,host:'10.68.4.209:10001',priority:1},...{_id:2,host:'10.68.4.209:10000',arbiterOnly:true}]};{"_id":"policydb","members":[{"_id":0,"host":"10.68.4.209:10002","priority":2},{"_id":1,"host":"10.68.4.209:10001","priority":1},{"_id":2,"host":"10.68.4.209:10000","arbiterOnly":true}]}rs.initiate(config)#初始化rs.status()#查看集群状态10.68.4.29①创建data文件夹和log文件夹mdkir/data/{master,slave,arbiter}mkdir/data/log/mongodb/{master,slave,arbiter}-p②创建配置文件#master.confdbpath=/data/masterlogpath=/data/log/mongodb/master/mongodb.logpidfilepath=/var/run/mongo_master.pid#directoryperdb=truelogappend=truereplSet=policydb2port=10002oplogSize=10000fork=truenoprealloc=trueprofile=1slowms=200#slave.confdbpath=/data/slavelogpath=/data/log/mongodb/slave/mongodb.logpidfilepath=/var/run/mongo_slave.pid#directoryperdb=truelogappend=truereplSet=policydb2port=10001oplogSize=10000fork=truenoprealloc=trueprofile=1slowms=200#arbiter.confdbpath=/data/arbiterlogpath=/data/log/mongodb/arbiter/mongodb.logpidfilepath=/var/run/mongo_arbiter.pid#directoryperdb=truelogappend=truereplSet=policydb2port=10000oplogSize=10000fork=truenoprealloc=trueprofile=1slowms=200③启动mongodb/etc/init.d/mongodb_masterstart/etc/init.d/mongodb_slavestart/etc/init.d/mongodb_arbiterstart④配置主、备、中间节点:#/usr/local/mongodb/bin/mongo10.68.4.209:10002MongoDBshellversion:2.4.9connectingto:10.68.4.209:10002/test>useadminswitchedtodbadmin>config={_id:"policydb2",members:[{_id:0,主机:'10.68.4.29:10002',优先级:2},{_id:1,主机:'10.68.4.29:10001',优先级:1},...{_id:2,主机:'10.68.4.209:10000',仲裁rOnly:true}]};{"_id":"policydb","members":[{"_id":0,"host":"10.68.4.29:10002","priority":2},{"_id":1,"host":"10.68.4.29:10001","priority":1},{"_id":2,"host":"10.68.4.29:10000","arbiterOnly":true}]}rs.initiate(config)#初始化rs.status()#查看集群状态10.68.4.30①创建data文件夹和log文件夹mdkir/data/{master,slave,arbiter}mkdir/data/log/mongodb/{master,slave,arbiter}-p②创建配置文件#master.confdbpath=/data/masterlogpath=/data/log/mongodb/master/mongodb.logpidfilepath=/var/run/mongo_master.pid#directoryperdb=truelogappend=truereplSet=policydb3port=10002oplogSize=10000fork=truenoprealloc=trueprofile=1slowms=200#slave.confdbpath=/data/slavelogpath=/data/log/mongodb/slave/mongodb.logpidfilepath=/var/run/mongo_slave.pid#directoryperdb=truelogappend=truereplSet=policydb3port=10001oplogSize=10000fork=truenoprealloc=trueprofile=1slowms=200#arbiter.confdbpath=/data/arbiterlogpath=/data/log/mongodb/arbiter/mongodb.logpidfilepath=/var/run/mongo_arbiter.pid#directoryperdb=truelogappend=truereplSet=policydb3port=10000oplogSize=10000fork=trueprofile=trueprofile=1slowms=200③启动mongodb/etc/init.d/mongodb_masterstart/etc/init.d/mongodb_slavestart/etc/init.d/mongodb_arbiterstart④配置主、备、仲衣节主节:#/usr/local/mongodb/bin/mongo10.68.4.209:10002MongoDBshellversion:2.4.9connectingto:10.68.4.209:10002/test>useadminswitchedtodbadmin>config={_id:"policydb3",members:[{_id:0,host:'10.68.4.30:10002',优先级:2},{_id:1,host:'10.68.4.30:10001',priority:1},...{_id:2,host:'10.68.4.30:10000',arbiterOnly:true}]};{"_id":"policydb","members":[{"_id":0,"host":"10.68.4.30:10002","priority":2},{"_id":1,"host":“10.68.4.30:10001”，“优先级”：1}，{“_id”：2，“主机”：“10。10.68.4.209mkdir/data/config10.68.4.29mkdir/data/config10.68.4.30mkdir/data/config②准备配置服务器的配置文件三台服务器的配置服务器的配置文件一致#config.confdbpath=/data/configlogpath=/data/log/mongodb/config/mongodb.logpidfilepath=/var/run/mongo_config.piddirectoryperdb=truelogappend=trueport=10003fork=trueconfigsvr=true③启动配置服务器/etc/init.d/mongodb_configstart3.mongod创建配置mongos并开启分片模式①创建日志目录mkdir-p/data/log/mongodb/mongos/②准备mongos的配置文件#mongos.conflogpath=/data/log/mongodb/mongos/mongodb.logpidfilepath=/var/run/mongo_mongos.pidlogappend=t
