MongoDB 主從同步設置

MongoDB 主從同步設置

關於MongoDB的安裝及啓動參數說明能夠參考我以前轉載的《Ubuntu安裝MongoDB》與《Mongodb啓動命令mongod參數說明》

主從設置

Master： 192.168.111.103 Port：8001

Slave：192.168.111.104 Port：8001

啓動Master

mongod --dbpath /data/masterdb/ --master --oplogSize 64 --port 8001 --fork --logpath /var/logs/mongodb/mongod.log

啓動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能夠見到已經從Master複製數據

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