1. 单机
单机没密码纯内存配置:

2. 主从复制
举例：
- 1主1从、带密码、
RDB-AOF混合持久化 - 主节点端口为
6379，从节点端口为6380
2.1 主节点配置
vim /o
bind 0.0.0.0 protected-mode yes port 6379 tcp-backlog 511 timeout 0 tcp-keepalive 300 daemonize no supervised no pidfile /var/run/redis_6379.pid loglevel notice logfile "6379.log" dbfilename dump-6379.rdb requirepass 1q2w3e4r masterauth 1q2w3e4r databases 16 always-show-logo yes save "" stop-writes-on-bgsave-error yes rdbcompression yes rdbchecksum yes dir ./ slave-serve-stale-data yes slave-read-only yes repl-diskless-sync no repl-diskless-sync-delay 5 repl-disable-tcp-nodelay no slave-priority 100 lazyfree-lazy-eviction no lazyfree-lazy-expire no lazyfree-lazy-server-del no slave-lazy-flush no appendonly yes appendfilename "appendonly.aof" appendfsync everysec no-appendfsync-on-rewrite no auto-aof-rewrite-percentage 100 auto-aof-rewrite-min-size 64mb aof-load-truncated yes aof-use-rdb-preamble yes lua-time-limit 5000 slowlog-log-slower-than 10000 slowlog-max-len 128 latency-monitor-threshold 0 notify-keyspace-events "" hash-max-ziplist-entries 512 hash-max-ziplist-value 64 list-max-ziplist-size -2 list-compress-depth 0 set-max-intset-entries 512 zset-max-ziplist-entries 128 zset-max-ziplist-value 64 hll-sparse-max-bytes 3000 activerehashing yes client-output-buffer-limit normal 0 0 0 client-output-buffer-limit slave 256mb 64mb 60 client-output-buffer-limit pubsub 32mb 8mb 60 hz 10 aof-rewrite-incremental-fsync yes
2.2 主节点启动文件
vim start-6379.sh
PORT=6379 docker stop redis-${PORT} docker rm redis-${PORT} docker run --name redis-${PORT} \ -p ${PORT}:${PORT} \ -v /opt/redis/conf/${PORT}.conf:/etc/redis/redis.conf \ -v /opt/redis/data:/data \ -d redis:4.0 \ redis-server /etc/redis/redis.conf
2.3 从节点配置
vim /opt/redis/conf/6380.conf
bind 0.0.0.0 protected-mode yes port 6380 tcp-backlog 511 timeout 0 tcp-keepalive 300 daemonize no supervised no pidfile /var/run/redis_6380.pid loglevel notice logfile "6380.log" dbfilename dump-6380.rdb slaveof 192.168.28.130 6379 requirepass 1q2w3e4r masterauth 1q2w3e4r databases 16 always-show-logo yes save "" stop-writes-on-bgsave-error yes rdbcompression yes rdbchecksum yes dir ./ slave-serve-stale-data yes slave-read-only yes repl-diskless-sync no repl-diskless-sync-delay 5 repl-disable-tcp-nodelay no slave-priority 100 lazyfree-lazy-eviction no lazyfree-lazy-expire no lazyfree-lazy-server-del no slave-lazy-flush no appendonly yes appendfilename "appendonly.aof" appendfsync everysec no-appendfsync-on-rewrite no auto-aof-rewrite-percentage 100 auto-aof-rewrite-min-size 64mb aof-load-truncated yes aof-use-rdb-preamble yes lua-time-limit 5000 slowlog-log-slower-than 10000 slowlog-max-len 128 latency-monitor-threshold 0 notify-keyspace-events "" hash-max-ziplist-entries 512 hash-max-ziplist-value 64 list-max-ziplist-size -2 list-compress-depth 0 set-max-intset-entries 512 zset-max-ziplist-entries 128 zset-max-ziplist-value 64 hll-sparse-max-bytes 3000 activerehashing yes client-output-buffer-limit normal 0 0 0 client-output-buffer-limit slave 256mb 64mb 60 client-output-buffer-limit pubsub 32mb 8mb 60 hz 10 aof-rewrite-incremental-fsync yes
slaveof：启用主从模式配置主库ip和端口
slave-read-only：从节点是否只读
masterauth：设置访问master服务器的密码，如果主节点设置了密码必需添加该参数才能同步数据
2.4 从节点启动文件
vim start-6380.sh
PORT=6380 docker stop redis-${PORT} docker rm redis-${PORT} docker run --name redis-${PORT} \ -p ${PORT}:${PORT} \ -v /opt/redis/conf/${PORT}.conf:/etc/redis/redis.conf \ -v /opt/redis/data:/data \ -d redis:4.0 \ redis-server /etc/redis/redis.conf
2.5 查看主从节点状态
##进入主节点容器 docker exec -it redis-6379 bash ##通过密码登录redis redis-cli -a 1q2w3e4r ##查看主从信息 info replication
3. 主从复制+哨兵
sentinel是为了解决主从模式下，如果主节点由于故障下线了，自动升级从节点为主节点。
每个sentinel节点其实就是一个redis实例，与主从节点不同的是sentinel节点作用是用于监控redis数据节点的，而sentinel节点集合则表示监控一组主从redis实例多个sentinel监控节点的集合，比如有主节点master和从节点slave-1、slave-2 。
sentinel主节点端口为26379，sentinel从节点端口为26380
3.1 主节点配置
vim /opt/redis/conf/sentinel-26379.conf
port 26379 logfile "26379.log" sentinel myid 5fe8c1456f5080df3e485d44447e812e97ecd4d1 sentinel deny-scripts-reconfig yes daemonize no pidfile "/var/run/redis-sentinel.pid" dir "/tmp" sentinel monitor mymaster 192.168.28.130 6379 1 sentinel down-after-milliseconds mymaster 5000 sentinel auth-pass mymaster 1q2w3e4r
myid：唯一id，sentinel集群的各自myid参数必需唯一
sentinel monitor：只需配置主节点即刻，端口后面的数字代表指明当有多少个sentinel认为一个master失效时，master才算真正失效
sentinel down-after-milliseconds：需要多少失效时间，一个master才会被这个sentinel主观地认为是不可用的(默认30秒)
sentinel auth-pass：设置连接master和slave时的密码
3.2 主节点启动文件
vim start-sentinel-6379.sh
PORT=26379 docker stop redis-sentinel-${PORT} docker rm redis-sentinel-${PORT} docker run --name redis-sentinel-${PORT} \ -p ${PORT}:${PORT} \ -v /opt/redis/conf/sentinel-${PORT}.conf:/etc/redis/sentinel.conf \ -v /opt/redis/data:/data \ -d redis:4.0 \ redis-sentinel /etc/redis/sentinel.conf
3.3 从节点配置
vim /opt/redis/conf/sentinel-26380.conf
port 26380 logfile "26380.log" sentinel myid 5fe8c1456f5080df3e485d44447e812e97ecd4d2 sentinel deny-scripts-reconfig yes daemonize no pidfile "/var/run/redis-sentinel.pid" dir "/tmp" sentinel monitor mymaster 192.168.28.130 6379 1 sentinel down-after-milliseconds mymaster 5000 sentinel auth-pass mymaster 1q2w3e4r
3.4 从节点启动文件
vim start-sentinel-6380.sh
PORT=26380 docker stop redis-sentinel-${PORT} docker rm redis-sentinel-${PORT} docker run --name redis-sentinel-${PORT} \ -p ${PORT}:${PORT} \ -v /opt/redis/conf/sentinel-${PORT}.conf:/etc/redis/sentinel.conf \ -v /opt/redis/data:/data \ -d redis:4.0 \ redis-sentinel /etc/redis/sentinel.conf
3.5 查看哨兵状态
## 进入主节点容器 docker exec -it redis-sentinel-26379 bash ## 登录redis redis-cli -p 26379 ## 查看sentinel信息 info sentinel
3.6 spring boot 工程集成哨兵集群
把单机的spring.redis.host和spring.redis.port配置改成以下
##### redis配置 spring.redis.sentinel.master=mymaster spring.redis.sentinel.nodes=192.168.28.130:26379,192.168.28.130:26380 spring.redis.password=1q2w3e4r
4. cluster集群
以下例子用的是伪集群，真正的集群放到不同的机器即可。
- 端口是
7001-7006 - 工作目录：
/opt/redis-cluster
4.1 创建文件夹
首先创建一堆对应端口的文件夹，编辑创建脚本vim create.sh内容如下：
for i in `seq 7001 7006` do mkdir -p ${i}/data done
执行脚本：
sh create.sh
4.2 创建docker-compose配置
编辑环境配置vim .env内容如下
redis_path=/opt/redis-cluster
编辑vim docker-compose.yml内容如下:
version: '3.4' x-image: &default-image publicisworldwide/redis-cluster x-restart: &default-restart always x-netmode: &default-netmode host services: redis1: image: *default-image network_mode: *default-netmode restart: *default-restart volumes: - ${redis_path}/7001/data:/data environment: - REDIS_PORT=7001 redis2: image: *default-image network_mode: *default-netmode restart: *default-restart volumes: - ${redis_path}/7002/data:/data environment: - REDIS_PORT=7002 redis3: image: *default-image network_mode: *default-netmode restart: *default-restart volumes: - ${redis_path}/7003/data:/data environment: - REDIS_PORT=7003 redis4: image: *default-image network_mode: *default-netmode restart: *default-restart volumes: - ${redis_path}/7004/data:/data environment: - REDIS_PORT=7004 redis5: image: *default-image network_mode: *default-netmode restart: *default-restart volumes: - ${redis_path}/7005/data:/data environment: - REDIS_PORT=7005 redis6: image: *default-image network_mode: *default-netmode restart: *default-restart volumes: - ${redis_path}/7006/data:/data environment: - REDIS_PORT=7006
4.3 启动所有redis
执行以下命令
docker-compose up -d
4.4 部署cluster
通过inem0o/redis-trib镜像，编辑脚本vim redis-trib.sh内容如下:
docker run --rm -it inem0o/redis-trib create --replicas 1 192.168.28.130:7001 192.168.28.130:7002 192.168.28.130:7003 192.168.28.130:7004 192.168.28.130:7005 192.168.28.130:7006
运行脚本sh redis-trib.sh:
输入yes:
