Docker--------docker-compose LNMP实战

1. 背景

dockerfile 与 docker-compose 相关内容在前面文章已经详述，这里就不再一一说明。

3. 制作镜像

　 * 构建php dockerfile

#Php-fpm
#Version 1.0.1
#Author lisea
 
#Base Image
FROM centos:7
 
#Maintainer
MAINTAINER lisea [email protected]
 
#Commands

RUN rpm -ivh http://mirrors.aliyun.com/epel/epel-release-latest-7.noarch.rpm

RUN yum install php-fpm -y

RUN sed -i -e 's\listen = 127.0.0.1:9000\listen = 0.0.0.0:9000\g' -e 's\listen.allo

wed_clients = 127.0.0.1\;listen.allowed_clients = 127.0.0.1\g' /etc/php-fpm.d/www.c
onf

RUN sed -i 's\;daemonize = yes\daemonize = no\g' /etc/php-fpm.conf
 
EXPOSE 9000

CMD ["php-fpm"]

　 * 构建 php 镜像

1	`[[email protected] php-fpm]# docker build -t lisea/php-fpm:v1.0.1 .`

* 准备nginx配置nginx.conf文件

        sleep 10s
fi
/usr/bin/mysqld_safe

* 构建mariadb(mysql) dockerfile

#Mariadb

RUN yum install mariadb-server mariadb -y

ADD startup.sh /opt/startup.sh

RUN chmod +x /opt/startup.sh
 
EXPOSE 3306

CMD ["/bin/bash","/opt/startup.sh"]

* 构建 mysql 镜像

1	`[[email protected] mysql]# docker build -t lisea/mariadb:v1.0.1 .`

* 查看所有镜像

[[email protected] lnmp]# docker images

* 开始构建并运行 -d 指定后台运行

[[email protected] lnmp]# docker-compose up -d

Creating network "lnmp_default" with the default driver
Creating lnmp_lnmp_php_1 ... 
Creating lnmp_lnmp_mysql_1 ... 
Creating lnmp_lnmp_php_1

Creating lnmp_lnmp_php_1 ... done

Creating lnmp_lnmp_mariadb_1 ... done

Creating lnmp_lnmp_nginx_1 ... done

* 查看端口监听状态

[[email protected] lnmp]# netstat -lntp
Active Internet connections (only servers)

Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name

tcp6       0      0 :::22                   :::*                    LISTEN      975/sshd

5. 测试lnmp环境

　 * 路径切换到nginx web目录　[/data/www]

1	`[[email protected] lnmp]# cd /data/www/`

* index.php

3

<?php

  phpinfo();
?>

* 浏览器访问　ip:8080/index.php

6. 总结

以需求驱动技术，技术本身没有优略之分，只有业务之分。
