话说在虚拟机中会报各种错误,在真实的环境中就不会那么痛苦了。
想了一下虚拟机中报错的原因有。机器卡,处理的时间长就会抛出错误
还有虚拟机如果给的空间太小,也会报异常。
此处讲讲我的大致思路。
第一,选择三台服务器,最好不是虚拟的
第二,设计三台服务器的IP,端口,和各自的角色
第三,检查防火墙有没有关闭,时间是不是同步
如果上面都可以了,那你就可以操作了。
当然,mongodb版本和mongodb前提搭建就建在前面吧

wget http://fastdl.mongodb.org/linux/mongodb-linux-x86_64-2.0.4.tgz

解压mongodb文件

主机版本号不一样。我的是2.0.4

[root@mongodb40 ~]# tar zxvfmongodb-linux-x86_64-2.4.7.tgz

[root@mongodb40 ~]# mvmongodb-linux-x86_64-2.4.7 /home/mongodb

主机2

[root@mongodb41~]# tar zxvfmongodb-linux-x86_64-2.4.7.tgz

[root@mongodb41~]# mvmongodb-linux-x86_64-2.4.7 /home/mongodb

主机3

[root@mongodb250 ~]# tar zxvfmongodb-linux-x86_64-2.4.7.tgz

[root@mongodb250~]# mvmongodb-linux-x86_64-2.4.7 /home/mongodb

创建数据库目录

主机1172.16.0.40)配置文件

[root@mongodb115 ~]# mkdir -p/home/data/shard1_1

[root@mongodb115 ~]# mkdir -p/home/data/shard2_1

[root@mongodb115 ~]# mkdir -p/home/data/shard3_1

[root@mongodb115 ~]# mkdir -p/home/data/config                            #config server目录

[root@mongodb115 ~]# mkdir -p/home/config                                       #放配置文件

[root@mongodb115 ~]# mkdir -p/home/data/logs

这个地方的所有配置目录都放在/home/config目录下,切记切记啊,因为我在这里吃过亏,不知一次。

配置ReplicaSets

配置分片172.16.0.40上配置

[root@mongodb115 ~]# /home/mongodb/bin/mongo--port 11731

MongoDB shell version: 2.0.4

connecting to:127.0.0.1:11731/test

>config={_id:‘shard1‘,members:[{_id:0,host:‘172.16.0.40:11731‘,priority:2},{_id:1,host:‘172.16.0.41:11731‘},{_id:2,host:‘172.16.0.250:11731‘,arbiterOnly:true}]}

 

rs.initiate(config)

 

 

配置分片172.16.0.41上配置

[root@mongodb114 ~]# /home/mongodb/bin/mongo--port 11732

MongoDB shell version: 2.0.4

connecting to:127.0.0.1:11732/test

>config={_id:‘shard2‘,members:[{_id:0,host:‘172.16.0.40:11732‘,arbiterOnly:true},{_id:1,host:‘172.16.0.41:11732‘,priority:2},{_id:2,host:‘172.16.0.250:11732‘}]}

 

rs.initiate(config)

 

 

配置分片172.16.0.250上配置members里面的优先级priority值高的为主节点,对于仲裁点一定要加上arbiterOnly:true

[root@mongodb103 ~]# /home/mongodb/bin/mongo--port 11733

MongoDB shell version: 2.0.4

connecting to:127.0.0.1:11733/test

>config={_id:‘shard3‘,members:[{_id:0,host:‘172.16.0.40:11733‘},{_id:1,host:‘172.16.0.41:11733‘,arbiterOnly:true},{_id:2,host:‘172.16.0.25:11733‘,priority:2}]}

[root@mongodb115 ~]# /home/mongodb/bin/mongo--port 60000

MongoDB shell version: 2.0.4

connecting to:127.0.0.1:60000/test

mongos> use admin

switched to db admin

mongos>db.runCommand({addshard:"shard1/172.16.0.40:11731,172.16.0.41:11731, 172.16.0.250:11731"})

 

mongos>db.runCommand({addshard:"shard2/172.16.0.40:11732,172.16.0.41:11732, 172.16.0.250:11732"})

 

mongos> db.runCommand({addshard:"shard3/172.16.0.40:11733,172.16.0.41:11733, 172.16.0.250:11733"})

 

接下来激活分片,如下面的代码所示:   采用hash分片

db.runCommand({enablesharding:"test"})

db.runCommand({shardcollection:"test.users",key:{id:"hashed"}})

上面这个会报错,我这边版本不支持hashed分片,要把id:1
