1、mongodb主从配置
主从都在同一台服务器上，主起的是默认的端口，从起的是9999
1)master
/usr/local/mongodb/bin/mongod –master –dbpath /usr/local/mongodb/data/ –logpath /usr/local/mongodb/log/mongodb.log –directoryperdb &
2)slave
/web/mongodb/bin/mongod –slave –source 192.168.103.217:27017 –dbpath /web/mongodb/data/ –logpath /web/mongodb/log/mongo.log –directoryperdb &
2、互为主从
1)master
/usr/local/mongodb/bin/mongod –master –slave –source 192.168.103.217:9999 –dbpath /usr/local/mongodb/data/ –logpath /usr/local/mongodb/log/mongodb.log –directoryperdb &
2)slave
/web/mongodb/bin/mongod –port 9999 –master –slave –source 192.168.103.217:27017 –dbpath /web/mongodb/data/ –logpath /web/mongodb/log/mongo.log –directoryperdb &
3、带认证主从
1)master
在admin库添加用户root，local库添加用户repl
use admin
db.addUser('root','123')
db.auth('root','123')
use local
db.addUser('repl','123')
db.auth('repl','123')
/usr/local/mongodb/bin/mongod –master –auth –dbpath /usr/local/mongodb/data/ –logpath /usr/local/mongodb/log/mongodb.log –directoryperdb &
2)slave
在admin库添加用户root，local库添加用户repl
use admin
db.addUser('root','123')
db.auth('root','123')
use local
db.addUser('repl','123')
db.auth('repl','123')
/web/mongodb/bin/mongod –port 9999 –slave –source 192.168.103.217:27017 –auth –dbpath /web/mongodb/data/ –logpath /web/mongodb/log/mongo.log –directoryperdb &
4、测试
主从的话，在主上写，看是否能够同步到从库
互为主从，则分别在两个数据库上写数据，看能否同步到另一个数据库
