MongoDB 主从同步设置
关于MongoDB的安装及启动参数说明可以参考我之前转载的《Ubuntu安装MongoDB》与《Mongodb启动命令mongod参数说明》
主从设置
Master： 192.168.111.103 Port：8001
Slave：192.168.111.104 Port：8001
启动Master
mongod --dbpath /data/masterdb/ --master --oplogSize 64 --port 8001 --fork --logpath /var/logs/mongodb/mongod.log启动Slave
mongod --dbpath /data/slavedb/ --slave --source 192.168.111.103:8001 --oplogSize 64 --port 8001 --fork --logpath /var/logs/mongodb/mongod.log
查看Slave log可以见到已经从Master复制数据

停用MongoDB
mongo -port 8001 use admin db.shutdownServer() exit
修复MongoDB
mongod --dbpath /data/masterdb/ repair mongod --dbpath /data/slavedb/ repair
