使用Docker Compose搭建高可用Redis集群( 二 )

Redis


3. Redis服务器docker-compose.yml文件

  • 192.168.0.210服务器上部署两个Redis服务(Redis主服务1、Redis从服务2)的docker-compose-redis.yml文件

  • 192.168.0.195服务器上部署Redis服务(Redis从服务3)的docker-compose-redis-slave.yml文件

  • 192.168.0.210主Redis配置文件，配置端口26381 ， Redis密码 ， 并将配置文件redis.conf上传至/opt/container/redis/master/conf目录
Appendonly yesport 26381appendfilename appendonly.aofappendfsync everysecauto-aof-rewrite-min-size 10Mauto-aof-rewrite-percentage 100requirepass "设置密码" masterauth "设置密码" replica-read-only no
  • 192.168.0.210从Redis配置文件，配置端口26382，密码，并将配置文件redis.conf上传至/opt/container/redis/slave1/conf目录
appendonly yesport 26382appendfilename appendonly.aofappendfsync everysecauto-aof-rewrite-min-size 10Mauto-aof-rewrite-percentage 100requirepass "设置密码" replicaof 192.168.0.210 26381masterauth "设置密码" replica-read-only no
  • 192.168.0.195从Redis配置文件 ， 配置端口26383，密码，并将配置文件redis.conf上传至/opt/container/redis/slave2/conf目录
appendonly yesport 26383appendfilename appendonly.aofappendfsync everysecauto-aof-rewrite-min-size 10Mauto-aof-rewrite-percentage 100requirepass "设置密码" replicaof 192.168.0.210 26381masterauth "设置密码" replica-read-only no4. 准备Redis哨兵的配置文件，每个Redis服务对应一个哨兵配置
  • 192.168.0.210主Redis哨兵配置文件，配置哨兵sentinel实例运行的端口36381，Redis密码，并将配置文件sentinel.conf上传至/opt/container/redis/sentinel/conf目录
【使用Docker Compose搭建高可用Redis集群】# 哨兵sentinel实例运行的端口port 36381daemonize nopidfile /var/run/redis-sentinel.piddir /tmpsentinel monitor mymaster 192.168.0.210 26381 2sentinel auth-pass mymaster "Redis密码"# 指定多少毫秒之后 主节点没有应答哨兵sentinel 此时 哨兵主观上认为主节点下线 默认30秒sentinel down-after-milliseconds mymaster 30000# 指定了在发生failover主备切换时最多可以有多少个slave同时对新的master进行同步,这个数字越?。?完成failover所需的时间就越长sentinel parallel-syncs mymaster 1# 故障转移的超时时间sentinel failover-timeout mymaster 180000sentinel deny-scripts-reconfig yes
