一、概述
在上一篇文章介绍了nginx+php-fpm，链接如下：
https://www.cnblogs.com/xiao987334176/p/12918413.html
nginx和php-fpm是2个独立的镜像，在实际环境部署过程中，发现配置比较麻烦，排错比较耗费实际。
因此，需要将nginx和php-fpm 这2个镜像合并为一个。
二、nginx+php-fpm封装
目录结构
由于crunchgeek/php-fpm:7.3-r7 镜像比较大，有1.08GB。
因此需要使用alpine:3.11重新封装才行。
在dockerhub上面，php已经有官方的镜像了，php:7.3-fpm-alpine3.11。
由于项目php7cms依赖于组件mysqli，因此需要额外安装才行。
新建目录/opt/alpine_nginx_php7.3，结构如下：
./ ├── default.conf ├── dockerfile ├── index.html ├── php.ini ├── repositories └── run.sh
default.conf
server { listen 80; server_name localhost; root /var/www/html; index index.html index.htm index.nginx-debian.html; location / { try_files $uri $uri/ =404; } location ~ .php$ { fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } }
dockerfile
FROM php:7.3-fpm-alpine3.11 ADD repositories /etc/apk/repositories ADD default.conf / ADD index.html / ADD run.sh / ADD php.ini /usr/local/etc/php/ RUN apk update && apk add nginx && apk add m4 autoconf make gcc g++ linux-headers && docker-php-ext-install pdo_mysql opcache mysqli && mkdir /run/nginx && mv /default.conf /etc/nginx/conf.d && mv /index.html /var/www/html && touch /run/nginx/nginx.pid && chmod 755 /run.sh && apk del m4 autoconf make gcc g++ linux-headers EXPOSE 80 EXPOSE 9000 ENTRYPOINT ["/run.sh"]
注意：这里我额外安装了pdo_mysql，因为某些php项目用的是这个模块。opcache是用来做性能加速的。
index.html
<!DOCTYPE html> <html> <head> <title>Welcome to nginx!</title> <style> body { 35em; margin: 0 auto; font-family: Tahoma, Verdana, Arial, sans-serif; } </style> </head> <body> <h1>Welcome to nginx!</h1> <p>If you see this page, the nginx web server is successfully installed and working.

此文件是从容器里面copy出来的，路径为：/usr/local/etc/php/php.ini-production
去除了注释和多余的空行。
此配置文件，修改了cgi.fix_pathinfo=0
如果需要更改其他配置，修改此文件即可。
repositories
https://mirrors.aliyun.com/alpine/v3.11/main/ https://mirrors.aliyun.com/alpine/v3.11/community/
这个是阿里云的alpine更新源
run.sh
#!/bin/sh # 后台启动 php-fpm -D # 关闭后台启动，hold住进程 nginx -g 'daemon off;'
封装镜像
cd /opt/alpine_nginx_php7.3 docker build -t alpine_nginx_php7.3:1 .
查看镜像大小
# docker images|grep alpine_nginx_php7.3 alpine_nginx_php7.3 1 927ddfbdd027 14 minutes ago 78.4MB
可以看到这个镜像只有78.4MB。
运行镜像
docker run -it --name alpine_nginx_php7.3 -p 80:80 alpine_nginx_php7.3:1 .
访问首页
http://ip地址/
效果如下：
phpinfo页面
新建test.php
cd /opt/alpine_nginx_php7.3 vi test.php
内容如下：
<?php
phpinfo();
?>
拷贝到容器中
docker cp test.php alpine_nginx_php7.3:/var/www/html/
访问test.php
http://ip地址/test.php
效果如下：
三、运行PHP7CMS
下载源代码
源代码下载地址：
http://down.chinaz.com/soft/38829.htm
下载完成后，在windows10电脑中解压。
进入linux系统，创建空目录/opt/php7cms，将解压文件夹PHP7CMS的所有内容上传到/opt/php7cms中。
此时/opt/php7cms目录结构如下：
# tree -L 1 . ├── admin.php ├── api ├── cache ├── config ├── index.php ├── install.php ├── LICENSE ├── php7cms ├── README.md ├── static ├── template ├── uploadfile ├── 安装方法.txt └── 安装环境.docx
-L 参数表示控制深度，这里只展示第一层。
在此目录新建dockerfile
FROM alpine_nginx_php7.3:1 ADD default.conf /etc/nginx/conf.d ADD . /var/www/html/PHP7CMS RUN chown www-data:www-data -R /var/www/html
在此目录新建default.conf
server { listen 80; server_name localhost; root /var/www/html/PHP7CMS; index index.php index.html index.htm; location ~ .php$ { fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } }
这个文件用来将nginx默认的配置覆盖掉
封装镜像
cd /opt/php7cms docker build -t php7cms:1 .
运行docker
先将之前运行的nginx_php删除掉，再运行php7cms。否则会端口冲突
docker rm -f alpine_nginx_php7.3 docker run -d -it --restart=always --name php7cms -p 80:80 php7cms:1
由于php7cms依赖于mysql，还得运行一个mysql才行。
mkdir -p /data/mysql/data docker run -d --name mysql5.7 --restart=always -e MYSQL_ROOT_PASSWORD=abcd@1234 -p 3306:3306 -v /data/mysql/data:/var/lib/mysql mysql:5.7 --character-set-server=utf8mb4 --collation-server=utf8mb4_unicode_ci
新建空的数据库cms
# docker exec -it mysql5.7 /bin/bash # mysql -u root -pabcd@1234 mysql> create database cms default character set utf8mb4 collate utf8mb4_unicode_ci;
安装向导
