\n################################# REPLICATION #################################\n\n# Master-Slave replication. Use slaveof to make a Redis instance a copy of\n# another Redis server. A few things to understand ASAP about Redis replication.\n#\n# 1) Redis replication is asynchronous, but you can configure a master to\n#    stop accepting writes if it appears to be not connected with at least\n#    a given number of slaves.\n# 2) Redis slaves are able to perform a partial resynchronization with the\n#    master if the replication link is lost for a relatively small amount of\n#    time. You may want to configure the replication backlog size (see the next\n#    sections of this file) with a sensible value depending on your needs.\n# 3) Replication is automatic and does not need user intervention. After a\n#    network partition slaves automatically try to reconnect to masters\n#    and resynchronize with them.\n#\n# slaveof \n   \n    \n      slaveof 127.0.0.1 6380\n    \n   <\/pre>\n
