一、利用docker-machine搭建测试环境
docker-machine
创建两个虚拟机
docker-machine create -d virtualbox master
docker-machine create -d virtualbox slave
登录虚拟主机
docker-machine ssh master
docker-machine ssh slave
获得ip地址：
master：192.168.99.101
slave：192.168.99.102
二、在虚拟主机配置一主一从一哨兵
主redis
配置文件：redis_master.conf
daemonize no
pidfile "/var/run/redis.pid"
port 6379
timeout 300
loglevel warning
logfile "redis.log"
databases 1
rdbcompression yes
dbfilename "redis.rdb"
dir "/data"
requirepass password
masterauth password
maxclients 10000
maxmemory 1000mb
maxmemory-policy allkeys-lru
appendonly no
appendfsync alway
docker启动命令
docker run --name redis_master -p 6379:6379 -v $(pwd)/redis_master.conf:/data/redis_master.conf --restart=always -d redis:latest redis-server redis_master.conf
从redis
配置文件：redis_slave.conf
daemonize no
pidfile "/var/run/redis.pid"
port 6379
timeout 300
loglevel warning
logfile "redis.log"
databases 1
rdbcompression yes
dbfilename "redis.rdb"
dir "/data"
requirepass password
masterauth password
maxclients 10000
maxmemory 1000mb
maxmemory-policy allkeys-lru
appendonly no
appendfsync always
slaveof 192.168.99.101 6379
docker启动命令
docker run --name redis_slave -p 6379:6379 -v $(pwd)/redis_slave.conf:/data/redis_slave.conf --restart=always -d redis:latest redis-server
哨兵
配置文件：sentinel.conf
daemonize no
port 26379
dir "/tmp"
sentinel monitor mymaster 192.168.99.101 6379 1
sentinel down-after-milliseconds mymaster 60000
sentinel auth-pass mymaster password
sentinel config-epoch mymaster 0
sentinel leader-epoch mymaster 0
docker启动命令
docker run --name sentinel -p 26379:26379 -v $(pwd)/sentinel.conf:/data/sentinel.conf --restart=always -d redis:latest redis-sentinel sentinel.conf
三、测试主从同步、读写分离和哨兵监控
主动同步、读写分离
进入主redis
docker@master:~$ docker exec -it redis_master bash
root@4a788cdd0153:/data# redis-cli \\进入redis终端
127.0.0.1:6379> AUTH password \\登录
OK
127.0.0.1:6379> info replication \\查看信息

repl_backlog_active:1
repl_backlog_size:1048576
repl_backlog_first_byte_offset:1
repl_backlog_histlen:2679
127.0.0.1:6379> set cyf 123 \\设置键值对
OK
127.0.0.1:6379> keys * \\查看所有数据
1) "cyf"
127.0.0.1:6379> exit
root@4a788cdd0153:/data# exit
查看从redis
docker@slave:~$ docker exec -it redis_slave bash
root@69d8af53d06f:/data# redis-cli
127.0.0.1:6379> AUTH password

查看数据是否同步
127.0.0.1:6379> keys *
1) "cyf" \\数据已同步
查看是否能写入数据
127.0.0.1:6379> set kb 123
(error) READONLY You can't write against a read only replica. \\从redis不可写入数据
127.0.0.1:6379> exit
