1.服务器分配
os1:PRIMARY
os2:SECONDARY
os3:ARBITER
2.下载mongodb 对应的安装包
下载地址：https://www.mongodb.com/download-center/community
下载对应的安装包，如果当前版本没有对应系统的版本就找其他版本
3. mkdir /app
4.上传压缩包到/app目录并解压
tar -zxvf mongodb-linux-x86_64-4.0.16.tgz
mv mongodb-linux-x86_64-4.0.16 mongodb
5.创建配置文件
mkdir /app/mongodb/conf
cd /app/mongodb/conf
touch mongo.conf
mongo.conf文件内容
dbpath=/app/mongodb/data logpath=/app/mongodb/log/mongo.log pidfilepath=/app/mongodb/pid/mongo.pid directoryperdb=true logappend=true replSet=testrs bind_ip=192.168.5.16 port=27017 oplogSize=10000 fork=true noprealloc=true
6.创建mongo.conf文件中对应的目录
mkdir /app/mongodb/data
mkdir /app/mongodb/log
mkdir /app/mongodb/pid
7.复制mongodb文件 到其他主机
scp -r /app/mongodb os2:/app/
scp -r /app/mongodb os3:/app/
8.修改其他主机的mongo.conf文件中bind_ip为本机ip
见5mongo.conf文件内容
9.所有主机启动mongodb
cd /app/mongodb/bin
./mongod -f /app/mongodb/conf/mongo.conf
10.在非ARBITER的主机连接mongodb
cd /app/mongodb/bin
./mongo 192.168.5.17:27017
11.配置config
cfg={_id:"testrs",members:[{_id:0,host:"192.168.5.16:27017",priority:0},{_id:1,host:"192.168.5.17:27017",priority:1},{_id:2,host:"192.168.5.18:27017",arbiterOnly:true}]};
12.初始化
rs.initiate(cfg)
13.查看状态验证是否配置成功
rs.status()
