mongodb 副文本集搭建
1.每台机器都执行
tar -zxvfmongodb-linux-x86_64-amazon-3.4.2.tgz
mv mongodb-linux-x86_64-amazon-3.4.2mongodb
cd mongodb
mkdir data //创建 dbpath
//启动mongodb
bin/mongod --dbpath /usr/local/mongodb/data--replSet peterReplset --logpath /usr/local/mongodb/log --fork
2.任选一台机器 执行
.mongo\
> use admin\
switched to db admin
> config={ _id:"peterReplset", members:[
... {_id:0,host:"192.168.188.170:27017"},
