MongoDB 2.6.4 主从同步
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
單機主從模式
1：啟動master

關閉MongoDB?：
方法一：

報錯，發現日志文件不存在
[jifeng@jifeng04 mongodb-linux-x86_64-2.6.4]$ mongod --dbpath /home/jifeng/mongodb-linux-x86_64-2.6.4/data --master --rest --nojournal --fork --logpath /home/jifeng/mongodb-linux-x86_64-2.6.4/log/mongod.log 2014-09-05T16:12:09.321+0800 ** WARNING: --rest is specified without --httpinterface, 2014-09-05T16:12:09.322+0800 ** enabling http interface about to fork child process, waiting until server is ready for connections. forked process: 24061 child process started successfully, parent exiting啟動成功,rest有問題
