连接到其中一个mongos（10.0.0.51），做以下配置 （1）连接到mongs的admin数据库 # su - mongod $ mongo 10.0.0.51:38017/admin （2）添加分片 db.runCommand( { addshard : "sh1/10.0.0.51:38021,10.0.0.51:38022,10.0.0.51:38023",name:"shard1"} ) db.runCommand( { addshard : "sh2/10.0.0.51:38024,10.0.0.51:38025,10.0.0.51:38026",name:"shard2"} ) （3）列出分片 mongos> db.runCommand( { listshards : 1 } ) （4）整体状态查看 mongos> sh.status();
mongo --port 38017 admin admin> ( { enablesharding : "数据库名称" } ) eg： admin> db.runCommand( { enablesharding : "test" } )
### 创建索引 use test > db.vast.ensureIndex( { id: 1 } ) ### 开启分片 use admin > db.runCommand( { shardcollection : "test.vast",key : {id: 1} } )
admin> use test test> for(i=1;i<1000000;i++){ db.vast.insert({"id":i,"name":"shenzheng","age":70,"date":new Date()}); } test> db.vast.stats()
shard1: mongo --port 38021 db.vast.count(); shard2: mongo --port 38024 db.vast.count();
对oldboy库下的vast大表进行hash 创建哈希索引 （1）对于oldboy开启分片功能 mongo --port 38017 admin use admin admin> db.runCommand( { enablesharding : "oldboy" } ) （2）对于oldboy库下的vast表建立hash索引 use oldboy oldboy> db.vast.ensureIndex( { id: "hashed" } ) （3）开启分片 use admin admin > sh.shardCollection( "oldboy.vast", { id: "hashed" } ) （4）录入10w行数据测试 use oldboy for(i=1;i<100000;i++){ db.vast.insert({"id":i,"name":"shenzheng","age":70,"date":new Date()}); } （5）hash分片结果测试 mongo --port 38021 use oldboy db.vast.count(); mongo --port 38024 use oldboy db.vast.count();
