docker安装运行Redis

第一步：下拉redis
docker pull redis:7.2.4
我下拉的是目前最新版本，也就是7.2.4版本
docker ps
查看容器运行情况

第二步：挂载目录
mkdir -p /home/user/lyapp/redis/conf /home/user/lyapp/redis/data

第三步：新建并修改配置文件
在 /path/redis/conf/下新建 redis.conf文件，即/home/user/lyapp/redis/conf/redis.conf
我的配置文件如下，大家可以直接复制进redis.conf

# bind 192.168.1.100 10.0.0.1
# bind 127.0.0.1 ::1
#bind 127.0.0.1

第四步：配置防火墙对外开放端口
开放6379端口
firewall-cmd --zone=public --add-port=6379/tcp --permanent
重启防火墙
systemctl restart firewalld
重启docker
systemctl restart docker

第五步：启动redis
# 创建redis容器并运行
podman run -p 6380:6379 \
--name redis \
--privileged=true \
-v /home/user/lyapp/redis/conf/redis.conf:/etc/redis/redis.conf \
-v /home/user/lyapp/redis/data:/data \
-d docker.io/library/redis:7.2.4 \
redis-server /etc/redis/redis.conf

第六步：测试redis
进入redis容器
docker exec -it redis /bin/bash
连接redis服务器
redis-cli -a root
Ping一下
ping
如果回应Pong，则说明连接正确

常见错误
(error) NOAUTH Authentication required.
密码错误，检查redis密码，可以在之前修改的配置文件里查看redis.conf里的requirepass属性
