Dockerfile构建lamp镜像

1、构建目录

[root@docker ~]# mkdir compose_lamp
[root@docker ~]# cd compose_lamp/

2、编写Docekerfile

[root@docker compose_lamp]# vim Dockerfile
#基础镜像
FROM centos:7#维护该镜像的用户信息
MAINTAINER Crushlinux <[e-mail]>#安装httpd
RUN yum -y install httpd#安装mysql 和phpRUN rpm --rebuilddb && yum -y install mariadb-devel mariadb-server mariadb php php-fpm#修改php-fpm 配置文件允许nginx 访问#设置环境变量，便于管理
ENV MARIADB_USER root
ENV MARIADB_PASS 123456#mysql 数据库授权
ADD db_init.sh /root/db_init.sh
RUN chmod 775 /root/db_init.sh
RUN /root/db_init.sh#添加测试页面
ADD index.php /usr/share/httpd/html/index.php#定义时区
RUN ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime#分别开启80 端口，443 端口，9000 端口，3360 端口
EXPOSE 80
EXPOSE 9000
EXPOSE 3306#复制脚本，设置权限，启动容器时启动该脚本
ADD run.sh /run.sh
RUN chmod 775 /run.sh
CMD ["/run.sh"]

3、编写 db_init.sh

[root@docker compose_lamp]# vim db_init.sh
#!/bin/bash
/usr/bin/mysql_install_db --user=mysql
sleep 3
/usr/bin/mysqld_safe &
sleep 3
mysql -e "use mysql; grant all privileges on *.* to '$MARIADB_USER'@'%' identified by '$MARIADB_PASS' with grant option;"
h=$(hostname)
mysql -e "use mysql; update user set password=password('$MARIADB_PASS') where user='$MARIADB_USER' and host='$h';"
mysql -e "flush privileges;"

4、编写 index.php

[root@docker compose_lamp]# vim index.php <?php
phpinfo();
?>

5、编写 default.conf 

[root@docker compose_lamp]# vim default.conf server {listen       80;server_name  localhost;location / {root   /usr/share/httpd/html;index  index.html index.php index.htm;}location ~ \.php$ {root           /usr/share/httpd/html;fastcgi_pass   127.0.0.1:9000;fastcgi_index  index.php;fastcgi_param  SCRIPT_FILENAME  /usr/share/httpd/html$fastcgi_script_name;include        fastcgi_params;}
}

6、编写 run.sh

[root@docker compose_lamp]# vim run.sh #!/bin/bash
/usr/sbin/httpd && /usr/sbin/php-fpm && /usr/bin/mysql_safe
~                                                                    

7、构建镜像

[root@docker compose_lamp]# docker build -t lamp:new .
[root@docker compose_lamp]# docker images lamp:new
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
lamp                new                 47a211277660        14 minutes ago      913 MB

8、测试容器
