redis主从操作

一.命令模式启动从服务器

  1.启动从服务器

    ./redis-server --port 6380 --slaveof 127.0.0.1 6379

    主从同步成功

    90677:S 06 May 07:33:08.594 * MASTER <-> SLAVE sync: receiving 254 bytes from master
    90677:S 06 May 07:33:08.594 * MASTER <-> SLAVE sync: Flushing old data
    90677:S 06 May 07:33:08.594 * MASTER <-> SLAVE sync: Loading DB in memory
    90677:S 06 May 07:33:08.594 * MASTER <-> SLAVE sync: Finished with success

     注意:从redis默认无法执行写入操作.
    127.0.0.1:6380> set ee 22
    (error) READONLY You can't write against a read only slave.

  2.从服务器切换主服务器

    slaveof no one 不是任何服务器的从服务器
