docker 网络、wordpress+mysql搭建博客

[root@cka-master ~]# docker network list  #列出网络

#briage 网络就相当于虚拟机的NAT网络，每个容器都有自己的网络空间
#host  与宿主机共享网络
#none 无网络，一般用于测试
#创建网络

wordpress + mysql 实现个人博客

#拉取镜像
docker pull hub.c.163.com/library/wordpress
docker pull hub.c.163.com/library/mysql

#查看数据卷
[root@cka-node1 ~]# docker history  hub.c.163.com/library/wordpress:latest  | grep -i volume 
<missing>      4 years ago   /bin/sh -c #(nop)  VOLUME [/var/www/html]       0B        

[root@cka-node1 ~]# docker history  hub.c.163.com/library/mysql   | grep -i volume 
<missing>      4 years ago   /bin/sh -c #(nop)  VOLUME [/var/lib/mysql]      0B  

#运行数据库
[root@cka-node1 ~]# mkdir /data
[root@cka-node1 ~]# docker run -d --name db -- restart=always -v /data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=zhanghao -e MYSQL_DATABASE=wordpress hub.c.163.com/library/mysql

#运行wordpress，选一种方法即可
一、
查看数据库服务器地址
[root@cka-node1 ~]# docker inspect db   | grep IPAddress
            "SecondaryIPAddresses": null,
            "IPAddress": "172.17.0.2",
                    "IPAddress": "172.17.0.2",

[root@cka-node1 ~]# docker run -d --name blog --restart=always -p 80:80 -v /blog:/var/www/html -e WORDPRESS_DB_NAME=wordpress -e  WORDPRESS_DB_HOST=172.17.0.2 -e WORDPRESS_DB_USER=root -e WORDPRESS_DB_PASSWORD=zhanghao   
二、
docker run -d --name blog --restart=always -p 80:80 -v /blog:/var/www/html --link=db:mysql  hub.c.163.com/library/wordpress

访问宿主机：http://192.168.4.61 (192.168.4.61是我宿主机的IP) ，此时wordpress就搭建出来了，如下图按照提示初始化即可
