安装mongodb

更新系统

yum update

添加源

vim /etc/yum.repos.d/mongodb-org-2.6.repo

粘贴复制

[mongodb-org-3.2]
name=MongoDB Repository
baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/3.2/x86_64/
gpgcheck=0
enabled=1

安装mongodb

yum install -y mongodb-org

按照以上方式,搭建另外两台服务器

这样，我们就有三台服务器

es0

es1

es2

复制service~

cp /etc/init.d/mongod /etc/init.d/mongod-config
cp /etc/init.d/mongod /etc/init.d/mongod-db1
cp /etc/init.d/mongod /etc/init.d/mongod-db2
cp /etc/init.d/mongod /etc/init.d/mongod-db3

然后修改这些文件

vim /etc/init.d/mongod-db*

找到CONFIGFILE=/etc/mongod.conf依次修改CONFIGFILE=/etc/mongod-**.conf

配置示例

mongod-db*.conf

启动服务三台服务器都要做

service mongod-db1 start

service mongod-db2 start

service mongod-db3 start

service mongod-config start

cavacn commented 8 years ago

启动mongos

nohup mongos --port 3000 --configdb host1.port,host2.port,host3.port &

cavacn commented 8 years ago

连接mongos

mongo host:3000

mongos>use admin

mongos>db.runCommand({"addShard":"shardId/host:port"})

mongos>db.runCommand({"addShard":"shardId/host:port"})

mongos>db.runCommand({"addShard":"shardId/host:port"})

mongos>db.runCommand({listshards:1}) #查看状态

开启分片功能

mongos>db.runCommand({"enablesharding":"库名"})

{ "ok" : 1 }

mongos> db.runCommand({"shardcollection":"库名.表名","key":{_id:'hashed'}}) 

{ "collectionsharded" : "库名.表名", "ok" : 1 }
