【Redis】多机部署Redis-sentinel

1. Redis-sentinel配置文件

注意不同服务器上的Redis版本需要相同，否则可能因为RDB文件不同而导致Redis主从同步失败。

bind 0.0.0.0	// 任何ip都可以连接
port 27001		// 本机的端口
daemonize yes	// 后台运行
sentinel announce-ip "xxx.xxx.xxx.xxx"	// 本机的ip
sentinel monitor mymaster xxx.xxxx.xxxx.xxx 6379 2	// masterRedis的ip 端口 要有多少个sentinel票可以选为master
sentinel down-after-milliseconds mymaster 5000
sentinel failover-timeout mymaster 60000
sentinel auth-pass mymaster xxxx // 密码
dir "/root/sentinel/sentinel"
logfile "a.log"
# Generated by CONFIG REWRITE
protected-mode no

2. SpringBoot配置Redis-sentinel

application.yaml:

spring:
  redis:
    password: "xxx" // Redis密码
    sentinel:
      master: mymaster
      nodes:
        - xxx.xxxx.xxx.xxx:27001
        - xxx.xxxx.xxx.xxx:27001
        - xxx.xxxx.xxx.xxx:27001

在启动类中注册配置类Bean

@SpringBootApplication
public class RedisDemoApplication {

    @Bean
    public LettuceClientConfigurationBuilderCustomizer clientConfigurationBuilderCustomizer() {
        return clientConfigurationBuilder -> clientConfigurationBuilder.readFrom(ReadFrom.REPLICA_PREFERRED);
    }

    public static void main(String[] args) {
        SpringApplication.run(RedisDemoApplication.class, args);
        System.out.println("启动成功");
    }

}
