1. 工程准备

将安装包、配置文件、启动脚本统一放置到redis-m-s工程中。

2. 基于Dockerfile构建

2.1 拷贝工程到工作目录

# 设置工作目录
WORKDIR ${WORK_DIR}

# 文件拷贝：将所有本地文件拷贝到容器目录
COPY ./redis-m-s ${WORK_DIR}/redis-m-s

2.2 安装依赖包

RUN yum -y install make gcc gcc-c++

2.3 解压redis安装包、编译、安装

RUN tar -xzvf ${WORK_DIR}/redis-m-s/app/redis-${REDIS_VERSION}.tar.gz && \
    cd redis-${REDIS_VERSION} && \
    make  && make PREFIX=${SRC_APP_DIR}/redis install && \

2.4 拷贝配置文件到安装目录

拷贝配置文件和启动脚本

	mkdir -p ${SRC_APP_DIR}/redis/bin/ && \
	mkdir -p ${SRC_APP_DIR}/redis/conf/ && \
	cp ${WORK_DIR}/redis-m-s/conf/* ${SRC_APP_DIR}/redis/conf && \
	cp ${WORK_DIR}/redis-m-s/bin/* ${SRC_APP_DIR}/redis/bin && \
	chmod +x ${SRC_APP_DIR}/redis/bin/start_redis.sh && \

清理安装包

	cd ${WORK_DIR} && \
	rm -rf redis-${REDIS_VERSION}

3. 配置文件

3.1 redis-master.conf

基于安装目录下redis.conf进行修改，主要修改项：

bind 0.0.0.0
protected-mode no
logfile /export/Logs/redis/master/redis.log
dir /export/Data/redis/db
requirepass your_pass

3.2 redis-slave.conf

基于安装目录下redis.conf进行修改，主要修改项如下，注意将master_ip替换为实际IP

bind 0.0.0.0
protected-mode no
logfile /export/Logs/redis/slave/redis.log
dir /export/Data/redis/db
replicaof master_ip 6379
masterauth your_pass
requirepass your_pass

3.3 sentinel-master.conf

基于安装目录下sentinel.conf进行修改，主要修改项如下，注意将master_ip替换为实际IP

logfile /export/Logs/redis/sentinel/sentinel.log
sentinel monitor redis-master master-ip 6379 1
sentinel auth-pass redis-master your_pass
sentinel down-after-milliseconds redis-master 30000
sentinel parallel-syncs redis-master 1
sentinel failover-timeout redis-master 180000
SENTINEL master-reboot-down-after-period redis-master 0
# 容器部署时需声明
sentinel announce-ip master_ip
sentinel announce-port 26379

3.4 sentinel-slave.conf

基于安装目录下sentinel.conf进行修改，主要修改项如下，注意将master_ip替换为实际IP

logfile /export/Logs/redis/sentinel/sentinel.log
sentinel monitor redis-master master-ip 6379 1
sentinel auth-pass redis-master your_pass
sentinel down-after-milliseconds redis-master 30000
sentinel parallel-syncs redis-master 1
sentinel failover-timeout redis-master 180000
SENTINEL master-reboot-down-after-period redis-master 0
# 容器部署时需声明
sentinel announce-ip slave_ip
sentinel announce-port 26379

4. 启动redis

4.1 redis主节点+哨兵启动

redis-server $REDIS_HOME/conf/redis-master.conf &
redis-sentinel $REDIS_HOME/conf/sentinel-master.conf &

4.2 redis从节点+哨兵启动

redis-server $REDIS_HOME/conf/redis-slave.conf &
redis-sentinel $REDIS_HOME/conf/sentinel-slave.conf &

5. 验证redis

5.1 登录主节点

下述 slave_ip 为从节点实际IP

# ./redis-cli
> auth your_pass
OK
> info replication
# Replication
role:master
connected_slaves:1
slave0:ip=slave_ip,port=6379,state=online,offset=28160117,lag=1

repl_backlog_histlen:1056970
>

5.2 登录哨兵

下述 master_ip 为主节点IP，slave_ip为从节点IP

./redis-cli -h master_ip -p 26379 
> sentinel sentinels redis-master

6. springboot应用集成redis

6.1 配置文件

spring:
  redis:
    sentinel:
      master: redis-master
      nodes:
        - redis://master_ip:26379
        - redis://slave_ip:26379
    password: your_pass

6.2 启动应用

启动应用时日志打印日志

:   master: redis://master_ip:6379 added
:   slave: redis://slave_ip:6379 added
:   sentinel: redis://slave_ip:26379 added
:   sentinel: redis://master_ip:26379 added
