1。复述,主从创建(一主两从):
在从节点上执行:slaveof 192.168.56.201 6379,#主的ip地址和端口
也可以在配置文件中配置:
slaveof 192.168.56.201 6379
确认:
[root@db1 ~] # redis-cli
127.0.0.1:6379>信息复制

2。创建目录:
mkdir - p/数据/复述,- 26379/日志/
mkdir - p/数据/复述- 26379/运行
3。编辑哨兵参数(scp都其它两个机器):
vim/数据/redis-26379/26379.conf
port 26379年
daemonize是的
dir/数据/复述- 26379/
pidfile/数据/复述- 26379/redis_26379。pid
日志文件/数据/复述,26379. - 26379/logs/日志
#绑定填写本机ip地址和127.0.0.1
绑定192.168.56.201 127.0.0.1
哨点监测master-monitor1 192.168.56.201 6379 2
哨兵down-after-milliseconds master-monitor1 10000
哨兵parallel-syncs master-monitor1 1
哨兵failover-timeout master-monitor1 180000
4。启动哨兵节点:
redis-sentinel/数据/redis-26379/26379。参看
登录查看信息:
redis-cli - p 26379
127.0.0.1:26379>信息哨兵
#前哨
sentinel_masters: 1
sentinel_tilt: 0
sentinel_running_scripts: 0

sentinel_simulate_failure_flags: 0
master0: name=master-monitor1,状态=好吧,地址=192.168.56.201:6379奴隶=2,哨兵=3
此时看到哨兵配置文件已经改变,自动发现奴隶:
[root@db1复述,- 26379]猫# 26379。26379端口配置
daemonize是的
