CentOS 1908 配置 Redis 5.0.7 一（单节点）

CentOS 1908 配置 Redis 5.0.7 二（主从复制）

CentOS 1908 配置 Redis 5.0.7 三（哨兵模式）

CentOS 1908 配置 Redis 5.0.7 五（集群新增 主从节点）​​​​​​​

  1. 安装 Redis 参见：CentOS 1908 配置 Redis 5.0.7 一（单节点）

  2. 进入 Redis 文件夹：

    1. [root@192 ~]# cd redis-5.0.7/
    2. [root@192 redis-5.0.7]#

  3. 创建集群文件夹并复制集群配置文件：

    1. mkdir cluster
    2. cd cluster
    3. cp ../redis.conf ./redis-6001.conf
    4. cp ../redis.conf ./redis-6002.conf
    5. cp ../redis.conf ./redis-6003.conf
    6. cp ../redis.conf ./redis-6004.conf
    7. cp ../redis.conf ./redis-6005.conf
    8. cp ../redis.conf ./redis-6006.conf

  4. 修改配置文件：

    1. 修改 redis6001.conf 文件：

      1. # 注释掉（远程连接）
      2. # bind 127.0.0.1
      4. # 将 yes 改为 no（取消保护）
      5. protected-mode no
      7. # 将端口改为 6001
      8. port 6001
      10. # 开启后台运行
      11. daemonize yes
      13. # 修改 pid 文件名
      14. pidfile /var/run/redis_6001.pid
      16. # 取消注释
      17. cluster-enabled yes
      19. # 集群配置文件
      20. cluster-config-file nodes-6001.conf
    2. 其他文件修改内容参看上面。

  5. 创建启动、停止 Redis 脚本：

    1. 启动脚本：

      1. vim start-all.sh

      内容如下：

      1. ../src/redis-server redis-6001.conf
      2. ../src/redis-server redis-6002.conf
      3. ../src/redis-server redis-6003.conf
      4. ../src/redis-server redis-6004.conf
      5. ../src/redis-server redis-6005.conf
      6. ../src/redis-server redis-6006.conf

    2. 停止脚本：

      1. vim stop-all.sh

      内容如下：

      1. ../src/redis-cli -p 6001 shutdown
      2. ../src/redis-cli -p 6002 shutdown
      3. ../src/redis-cli -p 6003 shutdown
      4. ../src/redis-cli -p 6004 shutdown
      5. ../src/redis-cli -p 6005 shutdown
      6. ../src/redis-cli -p 6006 shutdown

  6. 给启动脚本授权：

    1. chmod +x start-all.sh
    2. chmod +x stop-all.sh

  7. 启动：

    1. [root@192 cluster]# ./start-all.sh 
    2. 12163:C 17 Feb 2020 19:20:37.432 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo

    20. [root@192 cluster]#

  8. 开通端口：

    1. firewall-cmd --zone=public --add-port=6001/tcp --permanent
    2. firewall-cmd --zone=public --add-port=6002/tcp --permanent
    3. firewall-cmd --zone=public --add-port=6003/tcp --permanent
    4. firewall-cmd --zone=public --add-port=6004/tcp --permanent
    5. firewall-cmd --zone=public --add-port=6005/tcp --permanent
    6. firewall-cmd --zone=public --add-port=6006/tcp --permanent
    8. firewall-cmd --reload
    10. firewall-cmd --list-all

  9. 创建集群：
    必须使用 IP（否则远程连接不上）：

    1. ../src/redis-cli --cluster create --cluster-replicas 1 192.168.8.133:6001 192.168.8.133:6002 192.168.8.133:6003 192.168.8.133:6004 192.168.8.133:6005 192.168.8.133:6006

    信息如下：
    中间有提示，输入：yes

    1. >>> Performing hash slots allocation on 6 nodes...
    2. Master[0] -> Slots 0 - 5460
    3. Master[1] -> Slots 5461 - 10922
