拉取测试代码

git clone https://git.oschina.net/chunjian.feng/docker-training.git

build

docker build -t csphere/centos:7.1 .
docker build -t csphere/php-fpm:5.4 .
docker build -t csphere/mysql:5.5 .
docker build -t csphere/wordpress:4.2 ./wordpress/
　　Dockerfile非当前目录的情况

run

docker run -d -p 2222:22 --name base csphere/centos:7.1
docker run -d -p 8080:80 --name website csphere/php-fpm:5.4
docker run -d -p 3306:3306 --name dbserver csphere/mysql:5.5
docker run -d -p 3306:3306 -v /var/lib/docker/vfs/dir/mydata:/var/lib/mysql --name dbserver csphere/mysql:5.5
　　绑定本地目录需执行：chcon -Rt svirt_sandbox_file_t /var/lib/docker/vfs/dir/mydata
docker run -d -p 80:80 --name wordpress -e WORDPRESS_DB_HOST=192.168.29.131 -e WORDPRESS_DB_USER=admin -e WORDPRESS_DB_PASSWORD=csphere2015 csphere/wordpress:4.2
　　firewalld不可关闭
　　宿主机打开端口限制：firewall-cmd --zone=public --add-port=3306/tcp --permanent
　　firewall-cmd --reload

进入docker容器

docker exec -it website /bin/bash
docker exec -it dbserver /bin/bash
