docker安装mysql

# --name指定容器名字 -v目录挂载 -p指定端口映射  -e设置mysql参数 -d后台运行
sudo docker run -p 3306:3306 --name mysql \
-v /root/app/mysql/log:/var/log/mysql \
-v /root/app/mysql/data:/var/lib/mysql \
-v /root/app/mysql/conf:/etc/mysql \
-e MYSQL_ROOT_PASSWORD=root \
-d mysql:5.7


# 进入容器内部
docker exec -it 471 bash
whereis mysql
#mysql: /usr/bin/mysql /usr/lib/mysql /etc/mysql /usr/share/mysql


# 修改配置文件
vim /root/app/mysql/conf/my.cnf

[client]

# 重启
docker restart mysql
# 查看配置文件是否生效
docker exec -it 471 bash

docker 安装redis

# 创建挂载目录
mkdir -p /root/app/redis/conf
touch /root/app/redis/conf/redis.conf

# 启动
