CP mongodb.conf. /mongodbmaster-slave/slave/mongodb.conf

9. Modify the mongodb.conf in master, vim mongodb.conf

dbpath=/usr/java/mongodbmaster-slave/master/data/Dblogpath=/usr/java/mongodbmaster-slave/master/log/ mongodb.loglogappend=trueFork=truebind_ip=192.168.80.128Port =27020Master=truesource=192.168.80.128:27021    # slave IP and port
