使用Dockerfile制作LAMP环境镜像

编写Dockerfile

不修改默认页面

FROM centos:7
MAINTAINER "FOX"
COPY mysql.repo /etc/yum.repos.d/
COPY epel.repo /etc.yum.repos.d/
RUN yum clean all && yum makecache && yum install -y mysql-server php php-gd php-mysql httpd && \sed -i "s/#ServerName www.example.com:80/ServerName www.example.com:80/" /etc/httpd/conf/httpd.conf
EXPOSE 80/tcp 3306/tcp
COPY start.sh /opt/
RUN chmod +x /opt/start.sh
CMD ["/opt/start.sh"]

修改默认页面

该Dockerfile在宿主机安装有GUI时通过浏览器可看出效果。

FROM centos:7
MAINTAINER "FOX"
COPY mysql.repo /etc/yum.repos.d/
COPY epel.repo /etc.yum.repos.d/
RUN yum clean all && yum makecache && yum install -y mysql-server php php-gd php-mysql httpd && \sed -i "s/#ServerName www.example.com:80/ServerName www.example.com:80/" /etc/httpd/conf/httpd.conf   && \echo "<?php phpinfo(); ?>" > /var/www/html/index.php
EXPOSE 80/tcp 3306/tcp
COPY start.sh /opt/
RUN chmod +x /opt/start.sh
CMD ["/opt/start.sh"]

Start Script

#!/bin/bash
/usr/sbin/httpd &
/usr/sbin/mysqld --user=mysql &
tail -f /dev/null
