nginx+php-fpm docker镜像合二为一

小荷塘 發表於 2020-5-25 19:41:00

<h1>一、概述</h1>
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。
 
<h1>二、nginx+php-fpm封装</h1>
<h2>目录结构</h2>
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：
<div class="cnblogs_code">
<pre>./
├── default.conf
├── dockerfile
├── index.html
├── php.ini
├── repositories
└── run.sh</pre>
</div>
 
default.conf
<div class="cnblogs_code">
<pre>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;
}
}</pre>
</div>
 
dockerfile
<div class="cnblogs_code">
<pre>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"]</pre>
</div>
 
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
<div class="cnblogs_code">
<pre><!DOCTYPE html>
<html>

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
<div class="cnblogs_code">
<pre>https://mirrors.aliyun.com/alpine/v3.11/main/
https://mirrors.aliyun.com/alpine/v3.11/community/</pre>
</div>
这个是阿里云的alpine更新源
 
run.sh
<div class="cnblogs_code">
<pre>#!/bin/sh

# 后台启动
php-fpm -D
# 关闭后台启动，hold住进程
nginx -g 'daemon off;'</pre>
</div>
 
<h2>封装镜像</h2>
<div class="cnblogs_code">
<pre>cd /opt/alpine_nginx_php7.3
docker build -t alpine_nginx_php7.3:1 .</pre>
</div>
 
查看镜像大小
<div class="cnblogs_code">
<pre># docker images|grep alpine_nginx_php7.3
alpine_nginx_php7.3 1 927ddfbdd027 14 minutes ago 78.4MB</pre>
</div>
可以看到这个镜像只有78.4MB。
 
运行镜像
<div class="cnblogs_code">
<pre>docker run -it--name alpine_nginx_php7.3 -p 80:80 alpine_nginx_php7.3:1 .</pre>
</div>
 
访问首页
<div class="cnblogs_code">
<pre>http://ip地址/</pre>
</div>
效果如下：

<h2>phpinfo页面</h2>
新建test.php
<div class="cnblogs_code">
<pre>cd /opt/alpine_nginx_php7.3
vi test.php</pre>
</div>
 
内容如下：
<div class="cnblogs_code">
<pre><?php
phpinfo();
?></pre>
</div>
 
拷贝到容器中
<div class="cnblogs_code">
<pre>docker cp test.php alpine_nginx_php7.3:/var/www/html/</pre>
</div>
 
访问test.php
<div class="cnblogs_code">
<pre>http://ip地址/test.php</pre>
</div>
效果如下：
<img src="https://img2020.cnblogs.com/blog/1341090/202005/1341090-20200527200353468-4766143.png" alt="">
 
<h1>三、运行PHP7CMS</h1>
<h2>下载源代码</h2>
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：
<div class="cnblogs_code">
<pre># 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</pre>
</div>
-L 参数表示控制深度，这里只展示第一层。
 
在此目录新建dockerfile
<div class="cnblogs_code">
<pre>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</pre>
</div>
 
在此目录新建default.conf
<div class="cnblogs_code">
<pre>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;
}
}</pre>
</div>
这个文件用来将nginx默认的配置覆盖掉
 
<h2>封装镜像</h2>
<div class="cnblogs_code">
<pre>cd /opt/php7cms
docker build -t php7cms:1 .</pre>
</div>
 
<h2>运行docker</h2>
先将之前运行的nginx_php删除掉，再运行php7cms。否则会端口冲突
<div class="cnblogs_code">
<pre>docker rm -f alpine_nginx_php7.3
docker run -d -it --restart=always --name php7cms -p 80:80 php7cms:1</pre>
</div>
 
由于php7cms依赖于mysql，还得运行一个mysql才行。
<div class="cnblogs_code">
<pre>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</pre>
</div>
 
新建空的数据库cms
<div class="cnblogs_code">
<pre># docker exec -it mysql5.7 /bin/bash
# mysql -u root -pabcd@1234
mysql> create database cms default character set utf8mb4 collate utf8mb4_unicode_ci;</pre>
</div>
 
<h2>安装向导</h2>
我的服务器ip地址为：10.212.20.213
访问安装页面
<div class="cnblogs_code">
<pre>http://10.212.20.213/install.php</pre>
</div>
 
输入数据库连接信息
<img src="https://img2020.cnblogs.com/blog/1341090/202005/1341090-20200526133519961-950007884.png" alt="">
 
点击下一步后，提示安装完成。
<img src="https://img2020.cnblogs.com/blog/1341090/202005/1341090-20200526133615995-1724935339.png" alt="">
 
 
 
登录后台页面

默认用户名和密码都是admin
 
登录成功后，效果如下：
