mongo版本：mongodb-linux-x86_64-4.0.16.tgz
三台虚拟机
192.168.150.133 192.168.150.134 192.168.150.135
集群环境
2个分片复制集
shard1(192.168.150.133:27017 192.168.150.134:27017 192.168.150.135:27017)

解压/opt/mongodb目录下
tar -zxvf mongodb-linux-x86_64-4.0.16.tgz
创建/opt/mongo配置目录
添加(yidian_repl)复制集配置文件：mongo.conf (133/134/135)
#守护进程模式
fork = true
##数据目录
dbpath=/opt/mongo/data/db
##端口
port = 27017
bind_ip=0.0.0.0
##日志文件
logpath=/opt/mongo/logs/mongodb1.log
##日志追加
logappend=true
##复制集的名字
replSet=yidian_repl
smallfiles=true
#分片集群必须要的属性
shardsvr=true
添加(yidian_repl2)复制集配置文件：mongo2.conf
(133/134/135)
#守护进程模式
fork = true
##数据目录
dbpath=/opt/mongo/data/db
##端口
port = 27018
bind_ip=0.0.0.0
##日志文件
logpath=/opt/mongo/logs/mongodb2.log
##日志追加
logappend=true
##复制集的名字
replSet=yidian_repl2
smallfiles=true
#分片集群必须要的属性
shardsvr=true
启动副本集(yidian_repl)
/opt/mongodb/mongodb-linux-x86_64-4.0.16/bin/mongod -f /opt/mongo/mongo.conf
启动副本集(yidian_repl2)
/opt/mongodb/mongodb-linux-x86_64-4.0.16/bin/mongod -f /opt/mongo/mongo2.conf
登录复制集，添加初始化配置
进入mongo客户端
配置(yidian_repl)
/opt/mongodb/mongodb-linux-x86_64-4.0.16/bin/mongo -port 27017
进入27017客户端后，执行初始化命令
var rsconf = { _id:"yidian_repl", members:[
{_id:1,host:"192.168.150.133:27017"},
{_id:2,host:"192.168.150.134:27017"},
{_id:3,host:"192.168.150.135:27017"}
]
}
rs.initiate(rsconf);
rs.status();//查看状态
配置(yidian_rep2)
/opt/mongodb/mongodb-linux-x86_64-4.0.16/bin/mongo -port 27018
进入27018客户端后，执行初始化命令
var rsconf = { _id:"yidian_repl2", members:[
{_id:1,host:"192.168.150.133:27018"},
{_id:2,host:"192.168.150.134:27018"},
{_id:3,host:"192.168.150.135:27018"}
]
}
rs.initiate(rsconf);
搭建config节点复制集
创建config节点配置文件：mongo-cfg.conf (133/134/135)

启动配置复制集
/opt/mongodb/mongodb-linux-x86_64-4.0.16/bin/mongod -f /opt/mongo/mongo-cfg.conf
初始化配置节点
登录(任意一台)
/opt/mongodb/mongodb-linux-x86_64-4.0.16/bin/mongo -host 192.168.133 -port 28018
初始化命令
rs.initiate( {
_id : "csvr",
configsvr: true,
members: [
{ _id: 0, host: "192.168.150.133:28018" },
{ _id: 1, host: "192.168.150.134:28018" },
{ _id: 2, host: "192.168.150.135:28018" }
]
})
mongos节点配置
mongos配置文件：mongos.conf
systemLog:
destination: file
path: "/opt/mongo/mongos/log/mongos.log"
logAppend: true
net:
bindIp: 192.168.150.133

fork: true
启动mongos
/opt/mongodb/mongodb-linux-x86_64-4.0.16/bin/mongos -config /opt/mongo/mongos/mongos.conf
登录mongos节点
/opt/mongodb/mongodb-linux-x86_64-4.0.16/bin/mongo 192.168.150.133:28017
添加集群中的分片节点
切换admin：
use admin
添加shard1复制集
db.runCommand( { addshard : "yidian_repl/192.168.150.133:27017,192.168.150.134:27017,192.168.150.135:27017",name:"shard1"} )
添加shard2复制集
db.runCommand( { addshard : "yidian_repl2/192.168.150.133:27018,192.168.150.134:27018,192.168.150.135:27018",name:"shard2"} )
mongos查看分片状态：
sh.status()
