本文主要介绍了redis主从+哨兵搭建的实现示例，具体如下：
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 master_failover_state:no-failover master_replid:201648fb313a4359fea11e57c434afe8f372316d master_replid2:0000000000000000000000000000000000000000 master_repl_offset:28160410 second_repl_offset:-1 repl_backlog_active:1 repl_backlog_size:1048576 repl_backlog_first_byte_offset:27103441 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
