mongodb副本集仲裁节点搭建

服务器准备：

主节点192.168.100.106

从节点192.168.100.107

仲裁节点192.168.100.108

三台服务器：

关闭防火墙

service iptables stop

chkconfig iptables off

创建文件夹

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

上传mongodb-linux-x86_64-3.4.6.tgz并解压在/export/mongo目录下

tar -zxvf mongodb-linux-x86_64-3.4.6.tgz

mv mongodb-linux-x86_64-3.4.6 mongodb

cd /export/mongo/log

创建mongod.log文件

主节点：

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=主节点IP

oplogSize=10000

noprealloc=true

从节点：

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=从节点IP

oplogSize=10000

noprealloc=true

仲裁节点：

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

logappend =true

shardsvr =true

replSet =shard1

bind_ip=仲裁节点IP

oplogSize=10000

noprealloc=true

三台服务启动mongodb：

cd /export/mongo/mongodb/bin

./mongod -f /export/mongo/conf/mongo.conf

主节点：

cd /export/mongo/mongodb/bin

./mongo 主节点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)

--查看副本集情况

rs.status()

测试写入数据:
use db_test
db.tb_test01.insert( {"name":"yiibai tutorials"})
db.tb_test01.find()
