连接Redis进行测试

使用Docker集群也是一样的道理 。我们使用host模式(直接使用本机IP) ， 实现集群 。
准备工作
# 创建docker方式redis集群文件夹 mkdir -p /opt/redis/docker_redis_cluster # 拷贝准备好的文件到该目录 # 如果没有安装tree 先安装 yum install tree -y
使用tree查看目录结构, 只需要创建配置文件目录进行挂载修改 ， data和logs会自动挂载 。
. ├── docker-compose.yml ├── redis1 │ └── conf │ └── redis.conf ├── redis2 │ └── conf │ └── redis.conf ├── redis3 │ └── conf │ └── redis.conf ├── redis4 │ └── conf │ └── redis.conf ├── redis5 │ └── conf │ └── redis.conf └── redis6 └── conf └── redis.conf
再使用ls -al查询隐藏文件
[root@VM-0-5-centos docker_redis_cluster]# ls -al total 40 drwxr-xr-x 8 root root 4096 Sep 14 21:29 . drwxr-xr-x 8 root root 4096 Sep 12 22:49 .. -rw-r--r-- 1 root root 2953 Sep 14 21:29 docker-compose.yml -rw-r--r-- 1 root root 24 Sep 13 21:23 .env drwxr-xr-x 3 root root 4096 Sep 14 21:31 redis1 drwxr-xr-x 3 root root 4096 Sep 14 21:31 redis2 drwxr-xr-x 3 root root 4096 Sep 14 21:31 redis3 drwxr-xr-x 3 root root 4096 Sep 14 21:31 redis4 drwxr-xr-x 3 root root 4096 Sep 14 21:31 redis5 drwxr-xr-x 3 root root 4096 Sep 14 21:31 redis6
可以看到我们准备了docker-compose.yml, .env, redis.conf三种文件 。只需要修改.env的变量 ， 就可以通过docker-compose实现一键集群了 。
.env
# 服务器的IP地址 公网IP 注意开启防火墙端口 和 公网的安全组 SERVICE_IP=162.14.74.11 # 根目录 BASE_DIR=/opt/redis/docker_redis_cluster
编写docker-compose.yml
