下载程序

设置环境变量
[root@iZ2zejbqrpwrmr4mjy0u9fZ ~]# vim /etc/profile export PATH=/usr/local/mongodb/bin:$PATH
启动程序
[root@iZ2zejbqrpwrmr4mjy0u9fZ ~]# mongod --config /usr/local/mongodb/mongodb.conf about to fork child process,waiting until server is ready for connections. forked process: 32287 child process started successfully,parent exiting 说明程序已经正常启动
常用语句:
use admin 创建关于用户db.createUser({user:"admin",pwd:"admin",roles:[{role:"root",db:"admin"}]}) > rs.slaveOk()
主库插入语句
mongo 172.17.165.245:27017 创建新库 插入数据 > use new10 switched to db new10 > db.new10.save({"name":22200}) WriteResult({ "nInserted" : 1 }) > db.new10.find() { "_id" : ObjectId("5a7d7544ab1efad7a5581285"),"name" : 22200 }
从库进行查看
[root@iZ2zejbqrpwrmr4mjy0u9fZ mongodb]# mongo > use admin switched to db admin > db.auth("admin","admin") 1 > > rs.slaveOk() > show dbs admin 0.000GB config 0.000GB local 0.000GB master_slave 0.000GB new1 0.000GB new10 0.000GB teot 0.000GB test 0.000GB > switched to db new10 > db.new10.find() { "_id" : ObjectId("5a7d7544ab1efad7a5581285"),"name" : 22200 }
从库上面已经查看了主库上面的数据 说明主从已经搭建完毕
