Redis主从配置实践

1.进入安装redis目录,拷贝配置文件供slave使用

#cd /usr/local/redis/redis-2.8.17

#mkdir slave

#cp redis.conf slave/redis_slave_1.conf

#vim slave/redis_slave_1.conf

pidfile /var/run/redis_slave_1.pid

port 6401      #master: port 6379

logfile "logs/redis_slave_1.log"

dbfilename  dump_slave_1.rdb    #master:dbfilename  dump.rdb

slaveof 127.0.0.1 6379  #新增

2.启动主从机检验是否生效

# nohup src/redis-server >>logs/redis_master.log 2>& 1 &

[1] 2759

# nohup src/redis-server ./slave/redis_slave_1.conf >>logs/redis_slave1.log 2>& 1 &
[2] 2769

# tail -f logs/redis_slave.log
