今天给大家分享docker安装Redis图文教程，服务器版本为Centos8，希望对大家能有所帮助！

1.官网镜像版本查找

https://hub.docker.com/

2、拉取redis镜像

docker pullredis:7.0.2拉取redis镜像页面如下：

3、创建redis 服务器挂在目录

mkdir /home/redismkdir /home/redis/datamkdir /home/redis/conf

4、下载redis.conf 文件

dockers 下载的redis 默认是没有 redis.conf 文件的，需要从官网下载，也可以使用我下载好的redis.conf 文件。对应的版本是7.0.2 。下载后将文件上传到 /home/redis/conf 里面去。redis.conf 文件内容如下 已经去掉注释，如果需要特殊的配置去管网查看即可。

5、启动redis

docker run -p 6379:6379 --name redis -v /home/redis/conf/redis.conf:/etc/redis/redis.conf -v /home/redis/data:/data -d redis:7.0.2 redis-server /etc/redis/redis.conf --appendonly yes参数说明：

- p 6379:6379 端口映射：前表示宿主主机部分：后表示容器部分。--name redis  指定该容器名称，方便后续的查看和操作。-v 挂载目录，规则与端口映射相同。-d redis 表示后台启动redisredis-server /etc/redis/redis.conf  以配置文件启动redis，加载容器内的conf文件，最终找到的是挂载的目录/home/redis/conf/redis.confappendonly yes 开启redis 持久化

6、常用命令

docker ps |grep redis  #查看redis 是否启动成功

docker logs redis  # 查看docker容器中的redis日志

dockerexec-it redis /bin/bash #进入容器docker exec -it redis redis-server -v  #查看redis版本 7.0.2

设置防火墙命令

systemctl start firewalld #启动防火墙firewall-cmd --zone=public --add-port=6379/tcp --permanent # 设置Redis 6379 端口：firewall-cmd --zone=public --add-port=9000/tcp --permanent 设置Portainer 9000 端口firewall-cmd --reload #刷新防火墙

停止、重启、删除命令

docker stop redis #停止docker start redis  #重启docker rm redis  #删除容器docker rmi redis #删除镜像
