redis主从+keepalived

Redis主从+Keepalived是一种常见的Redis高可用方案。它的基本原理是通过使用Keepalived来实现Redis主从切换。具体步骤如下：

1. 首先，需要安装和配置Keepalived。可以按照以下步骤进行操作：
- 下载并解压Keepalived的源代码。
- 进入解压后的目录，并执行以下命令进行编译和安装：

     ./configure --prefix=/usr/local/keepalived/
     make
     make install

- 拷贝所需的文件到相应的目录，例如：

     cp /usr/local/src/keepalived-1.3.5/keepalived/etc/init.d/keepalived /etc/init.d/keepalived
     cp /usr/local/keepalived/sbin/keepalived /usr/sbin/
     cp /usr/local/keepalived/etc/sysconfig/keepalived /etc/sysconfig/
     mkdir -p /etc/keepalived/
     cp /usr/local/keepalived/etc/keepalived/keepalived.conf /etc/keepalived/keepalived.conf

- 修改keepalived.conf文件，根据实际情况配置虚拟IP（VIP）和监控脚本等参数。

2. 然后，需要配置Redis主从复制。可以按照以下步骤进行操作：
- 在Redis的主节点上，修改redis.conf文件，将`slaveof`参数设置为空，即不指定从节点。
- 在Redis的从节点上，修改redis.conf文件，将`slaveof`参数设置为主节点的IP和端口，例如：`slaveof <master_ip> <master_port>`。

3. 最后，启动Keepalived和Redis服务。
- 在Master节点上，启动Keepalived服务。
- 在Master和Slave节点上，分别启动Redis服务。

这样，当Redis的Master节点发生故障时，Keepalived会检测到故障并自动切换到Slave节点，确保Redis服务的高可用性。\[1\]\[2\]\[3\]
