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 # Replication role:master connected_slaves:1 slave0:ip=192.168.99.102,port=6379,state=online,offset=2679,lag=0 master_replid:24e1a9441d5df76943a737f890a293e054660653 master_replid2:0000000000000000000000000000000000000000 master_repl_offset:2679 second_repl_offset:-1 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
