1. Nginx

# 查询镜像
docker search nginx

# 拉取镜像
docker pull nginx

# 创建 nginx 容器，并将容器中的目录和宿主机目录进行挂载
docker run -di --name nginx -p 80:80 -v /mydata/docker_nginx/conf:/etc/nginx nginx

# 将容器内的配置文件拷贝到指定目录
docker cp nginx:/etc/nginx /mydata/docker-nginx/conf

# 重命名宿主机目录
mv /mydata/docker_nginx/nginx/ /mydata/docker-nginx/conf

2. MySQL

# 搜索镜像
docker search mysql

# 拉取镜像
docker pull mysql

# 创建容器
docker run -di --name mysql8 -p 3306:3306 -v /mydata/docker/mysql8/conf/my.cnf:/etc/mysql/my.cnf -v /mydata/docker/mysql8/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=123456 mysql

# 开机自启
docker update --restart=always 容器id

# docker desktop 运行镜像，挂载本地磁盘
# docker run -di --name mysql8 -p 3306:3306 -v D:/docker/mysql/config/my.cnf:/etc/mysql/my.cnf -v D:/docker/mysql/data:/var/lib/mysql --restart=always -e MYSQL_ROOT_PASSWORD=123456 mysql

# 进入容器
docker exec -it mysql8 bash

# 在容器内登录MySQL
mysql -u root -p

# 查看用户信息
select host,user,plugin,authentication_string from mysql.user;

# 备注：host 为 % 表示不限制 ip   localhost 表示本机使用    plugin 非 mysql_native_password 则需要修改密码
ALTER user 'root'@'%' IDENTIFIED WITH mysql_native_password BY 'system123456';
FLUSH PRIVILEGES;

-p ：代表端口映射，格式为 宿主机映射端口:容器运行端口。
-e ：代表添加环境变量 MYSQL_ROOT_PASSWORD 是 root 用户的登陆密码。连接容器中的 MySQL 时，只需要连接宿主机的 IP + 指定的映射端口即可。
注意：挂载本地磁盘时本地路径需要手动创建；本地配置文件不能为空，需要添加必要的配置信息比如如下配置：

[mysqld]
pid-file        = /var/run/mysqld/mysqld.pid
socket          = /var/run/mysqld/mysqld.sock
datadir         = /var/lib/mysql
secure-file-priv= NULL

# Custom config should go here
!includedir /etc/mysql/conf.d/

3. RabbitMQ

# 拉取镜像
docker pull rabbitmq

# 创建容器
docker run -di --name rabbitmq -p 5672:5672 -p 15672:15672 rabbitmq

# 进入容器
docker exec -it rabbitmq /bin/bash

# 开启管理界面
rabbitmq-plugins enable rabbitmq_management
