3. Redis主从部署

## 注意： 修改命令行中的服务器IP和端口 ### **安装Redis**（新部署） ``` ansible-playbook -i hosts/redis_hosts redis/redis.yml -e '{"redis_version":"3.2.13","master_host":"192.168.88.61"}' --tags install_redis ``` ### **初始化配置文件**（此时slaveof配置是注释的） ``` ansible-playbook -i hosts/redis_hosts redis/redis.yml -e '{"redis_version":"3.2.13","redis_port":"6379","master_host":"192.168.88.61"}' --tags init_redis_conf # 如果你想改配置，请用这个（如改密码、端口） ansible-playbook -i hosts/redis_hosts redis/redis.yml -e '{"redis_version":"3.2.13","redis_port":"6379","master_host":"192.168.88.61","redis_password":"custom_password","master_password":"custom_password"}' --tags init_redis_conf ``` ### **打开复制配置**（修改配置文件） ``` # 增加了when，master_host跳过此操作 ansible-playbook -i hosts/redis_hosts redis/redis.yml -e '{"redis_version":"3.2.13","redis_port":"6379","master_host":"192.168.88.61"}' --tags turn_on_replication ``` ### **设置密码** ``` nsible-playbook -i hosts/redis_hosts redis/redis.yml -e '{"redis_version":"3.2.13","redis_port":"6379","master_host":"192.168.88.61"}' --tags turn_on_local_auth,turn_on_master_auth ``` ### **启动服务** ``` ansible-playbook -i hosts/redis_hosts redis/redis.yml -e '{"redis_version":"3.2.13","redis_port":"6379","master_host":"192.168.88.61"}' --tags start_redis ``` ## **其他操作** ### **停止服务**（当需要重启生效时） ``` ansible-playbook -i hosts/redis_hosts redis/redis.yml -e '{"redis_version":"3.2.13","redis_port":"6379","master_host":"192.168.88.61"}' --tags stop_redis ``` ### **关闭Cluster**（按需，仅关闭，不同步新配置） ``` ansible-playbook -i hosts/redis_hosts redis/redis.yml -e '{"redis_version":"3.2.13","redis_port":"6379","master_host":"192.168.88.61"}' --tags turn_off_cluster ```
