MongoDB 主从同步设置

MongoDB 主从同步设置

关于MongoDB的安装及启动参数说明能够参考我以前转载的《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能够见到已经从Master复制数据

tail -f /var/logs/mongodb/mongod.log
