服務器准備：
主節點192.168.100.106
從節點192.168.100.107
仲裁節點192.168.100.108
三台服務器：
關閉防火牆
service iptables stop
chkconfig iptables off
創建文件夾
mkdir -p /export/mongo/data/db
mkdir -p /export/mongo/log
mkdir -p /export/mongo/key
mkdir -p /export/mongo/run
mkdir -p /export/mongo/conf
上傳mongodb-linux-x86_64-3.4.6.tgz並解壓在/export/mongo目錄下
tar -zxvf mongodb-linux-x86_64-3.4.6.tgz
mv mongodb-linux-x86_64-3.4.6 mongodb
cd /export/mongo/log
創建mongod.log文件
主節點：
vim /export/mongo/conf/mongo.conf
port =28007
fork =true
dbpath =/export/mongo/data/db
logpath =/export/mongo/log/mongod.log
pidfilepath=/export/mongo/run/28007.pid
logappend =true
shardsvr =true
replSet =shard1
bind_ip=主節點IP
oplogSize=10000
noprealloc=true
從節點：
vim /export/mongo/conf/mongo.conf
port =28008
fork =true
dbpath =/export/mongo/data/db
logpath =/export/mongo/log/mongod.log
pidfilepath=/export/mongo/run/28008.pid
logappend =true
shardsvr =true
replSet =shard1
bind_ip=從節點IP
oplogSize=10000
noprealloc=true
仲裁節點：
vim /export/mongo/conf/mongo.conf
port =28009
fork =true
dbpath =/export/mongo/data/db
logpath =/export/mongo/log/mongod.log
pidfilepath=/export/mongo/run/28009.pid

三台服務啟動mongodb：
cd /export/mongo/mongodb/bin
./mongod -f /export/mongo/conf/mongo.conf
主節點：
cd /export/mongo/mongodb/bin
./mongo 主節點IP:28007
use admin
config={_id:'shard1',members:[{_id:0,host:'118.1.2.81:28007'},{_id:1,host:'118.1.2.82:28008'},{_id:2,host:'118.1.2.74:28009', arbiterOnly:true}]}
rs.initiate(config)
--查看副本集情況
rs.status()
測試寫入數據:
use db_test
db.tb_test01.insert( {"name":"yiibai tutorials"})
db.tb_test01.find()
