Docker部署Nginx和Tomcat和MySql

Docker部署Nginx

# 搜索镜像 docker search nginx
# 下载镜像 docker pull nginx
# 启动镜像 docker run -d -p 2580:80 nginx     (把外部服务器2580 端口映射到nginx的80端口)

端口映射外网访问

进入nginx内部

[root@iZbp17g2ontiv6b4tu0incZ ~]# docker stop 66d211897c38

[root@iZbp17g2ontiv6b4tu0incZ ~]# docker exec -it myNginx /bin/bash

Docker部署Mysql（容器数据卷挂载）

# 运行容器做数据挂载
docker run -d -p 3306:3306 -v /home/mysql/conf:/etc/mysql/conf.d -v /home/mysql/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=123456 --name mysqlTest mysql

远程连接测试

进入Mysql

[root@fl02 ~]# docker exec -it ac8fa5b5d731 /bin/bash
root@ac8fa5b5d731:/# mysql -uroot -p -h localhost
