《实战录》导语
云端卫士《实战录》栏目定期会向粉丝朋友们分享一些在开发运维中的经验和技巧,希望对于关注我们的朋友有所裨益。本期分享人为云端卫士安全平台工程师田全磊,将带来Redis的主从服务器搭建。
Redis是一个简单快捷的key-value存储系统。它提供了丰富的数据存储结构,包括 lists, sets, ordered sets 以及 hashes ,当然还有和Memcached一样的 strings结构。同时Redis提供还对这些数据结构的丰富操作。
Redis哨兵模式介绍
Redis 的 Sentinel 功能用于管理多个 Redis 服务器,它主要提供了监控,提醒和自动故障迁移的功能。
1.监控(Monitoring): Sentinel 会不断地检查你的主服务器和从服务器是否运作正常。
2.提醒(Notification): 当被监控的某个 Redis 服务器出现问题时, Sentinel 可以通过 API 向管理员或者其他应用程序发送通知。
3.自动故障迁移(Automatic failover): 当一个主服务器不能正常工作时, Sentinel 会开始一次自动故障迁移操作, 它会将失效主服务器的其中一个从服务器升级为新的主服务器, 并让失效主服务器的其他从服务器改为复制新的主服务器; 当客户端试图连接失效的主服务器时, 集群也会向客户端返回新主服务器的地址, 使得集群可以使用新主服务器代替失效服务器。
安装
下载redis-2.8.19.tar.gz
解压tar zxf redis-2.8.19.tar.gz
安装cd redis-2.8.19
make && make install
每台机器上都同样安装redis
