一、环境

  1. centos7
  2. redis-3.0.4
  3. springboot2.x
  4. jdk1.8
  5. maven

二、配置redis的环境

本文是演示版本，采用一主二从一哨兵的模式

  1. master主机的配置对应redis.conf
# 是否以守护线程的形式运行，默认是no
daemonize yes
# 端口，默认6379
port 6379
# 日志输出文件
logfile "6379.log"
  1. 一号从机的配置对应redis6380.conf
# 是否以守护线程的形式运行，默认是no
daemonize yes
# 端口，默认6379
port 6380
# 日志输出文件
logfile "6380.log"
# 从属于主机6379
slaveof 192.168.43.243 6379
  1. 二号从机的配置对应redis6381.conf
# 是否以守护线程的形式运行，默认是no
daemonize yes
# 端口，默认6379
port 6381
# 日志输出文件
logfile "6381.log"
# 从属于主机6379
slaveof 192.168.43.243 6379

这里有一点需要注意的是，不能填写localhost或者127.0.0.1，否则会出现找不到主机的异常，这里就不贴出异常了

  1. 哨兵的配置对应sentinel.conf
# 表示监视的主机，这里也不能写127.0.0.1，否则会出现主机找不到的异常
sentinel monitor mymaster 192.168.43.243 6379 1
  1. 依次启动服务，进行验证
# 1. 主从验证
127.0.0.1:6379> info replication
# Replication
role:master
connected_slaves:2
slave0:ip=192.168.43.243,port=6380,state=online,offset=178172,lag=1
slave1:ip=192.168.43.243,port=6381,state=online,offset=178172,lag=1
master_repl_offset:178315
repl_backlog_active:1
repl_backlog_size:1048576
repl_backlog_first_byte_offset:2
repl_backlog_histlen:178314

127.0.0.1:6380> info replication

repl_backlog_size:1048576
repl_backlog_first_byte_offset:0
repl_backlog_histlen:0

127.0.0.1:6381> info replication
# Replication

master_repl_offset:0
repl_backlog_active:0
repl_backlog_size:1048576
repl_backlog_first_byte_offset:0
repl_backlog_histlen:0

# 2.读写分离验证
127.0.0.1:6381> set k1 v1
(error) READONLY You can't write against a read only slave.

127.0.0.1:6380> set k1 v1
(error) READONLY You can't write against a read only slave.

127.0.0.1:6379> set k2 v2
OK

# 3.验证备份
127.0.0.1:6380> get k2
"v2"
127.0.0.1:6381> get k2
"v2"

三、springboot整合redis

  1. 配置文件的配置
spring:
  redis:
    sentinel:
      master: mymaster
      nodes: 192.168.43.243:26379
    lettuce:
      pool:
        max-idle: 10
        max-active: 20
        min-idle: 5
        max-wait: 10000ms
  1. jar包的引入
  1. 错误的引入
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-redis</artifactId>
        </dependency>

        <dependency>

            <exclusions>

                </exclusion>
            </exclusions>
        </dependency>

会出现以下的错误

错误的意思就是说，数据库连接池没有实现，需要引入其它的实现jar包

  1. 正确的pom配置
