Docker 入门学习系列文章教程 - 让 php-fpm 跑的 owncloud 应用 docker 化 (十二)

随风发布于2017-03-163507 次阅读

1. 介绍

之前我们介绍过 owncloud 的部署 (部署 owncloud 与 phpMyAdmin (十一))，不管是 owncloud 还是 phpMyAdmin 都是 php 语言写的应用，owncloud 这个容器默认是跑在 apache 下，我不太喜欢，想改成 nginx+php-fpm 来跑。

2. 一个简单的实例

我们先来尝试一下用 nginx 结合 php-fpm 来跑 php 应用。

首先创建一个 docker-compose.yml 文件，内容如下：

version: '2'

services:
  web:
    image: nginx:latest
    ports:
      - 8080:80
    volumes:
      - ./code:/code
      - ./site.conf:/etc/nginx/conf.d/default.conf
  php:
    image: php:fpm
    volumes:
      - ./code:/code

数据卷./code这个目录是放 php 代码的，还有一个文件site.conf放的是 nginx 的配置。

它的内容如下：

server {
    index index.php index.html;
    server_name localhost;
    error_log  /var/log/nginx/error.log;
    access_log /var/log/nginx/access.log;
    root /code;

    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass php:9000;
        fastcgi_index index.php;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_param PATH_INFO $fastcgi_path_info;
    }
}

nginx 中使用 fastcgi 这个模块去连接 php-fpm。这些是 nginx 中 fastcgi 的基本配置啦。

然后我们试着写些 php 的代码，让它跑起来：

在当前目录下的 code 目录下新建index.php文件，内容如下:

<?php
echo phpinfo();
?>

然后一行docker-compose up命令就可以跑起来，使用 8080 端口查看效果。

3. 从 apache 迁移到 php-fpm

现在尝试把 owncloud 用 php-fpm 来跑。

之前我们的 docker-compose.yml 是这么写的：

version: '2'

services:

  owncloud:
    restart: always
    image: owncloud
    ports:
    - 18080:80
    volumes:
    - /home/hfpp2012/owncloud/html:/var/www/html:Z
    depends_on:
    - db
    dns:
    - 10.202.72.118
    - 10.202.72.116
    - 8.8.8.8

  db:
    restart: always
    image: mariadb
    environment:
    - MYSQL_ROOT_PASSWORD=my-secret-pw
    - MYSQL_DATABASE=owncloud_pro
    volumes:
    - /home/hfpp2012/owncloud/datadir:/var/lib/mysql

需要改造一下，把owncloud中的image和ports部分变一下：

image: owncloud:9.1.4-fpm
ports:
- 9000:9000

只是给 owncloud 换个版本，而且 php-fpm 默认是使用 9000 端口的。

使用docker-compose up或docker-compose restart重新把 owncloud 这个应用跑起来。

4. nginx 配置

接下来，我们把 nginx 的配置加上。

我们不用上面的那个很普通的关于 fastcgi 的配置，而 owncloud 的官方提供了一套比较标准的。

官方提供的那套 nginx 配置的网址是https://doc.owncloud.org/server/9.0/admin_manual/installation/nginx_examples.html

upstream php-handler {
    server 127.0.0.1:9000;
    #server unix:/var/run/php5-fpm.sock;
}

server {
    listen 80;
    server_name file.rails365.net;
    # enforce https
    return 301 https://$server_name$request_uri;
}

server {
    listen 443 ssl;
    server_name file.rails365.net;

    ssl_certificate           /home/hfpp2012/owncloud/ssl/file.rails365.net.key.pem;
    ssl_certificate_key       /home/hfpp2012/owncloud/ssl/file.rails365.net.key;
    # ssl_dhparam 
    ssl_dhparam /home/hfpp2012/owncloud/ssl/dhparam.pem; 

    # Add headers to serve security related headers
    # Before enabling Strict-Transport-Security headers please read into this topic first.
    #add_header Strict-Transport-Security "max-age=15552000; includeSubDomains";
    add_header X-Content-Type-Options nosniff;
    add_header X-Frame-Options "SAMEORIGIN";
    add_header X-XSS-Protection "1; mode=block";
    add_header X-Robots-Tag none;
    add_header X-Download-Options noopen;
    add_header X-Permitted-Cross-Domain-Policies none;

    # Path to the root of your installation
    root /home/hfpp2012/owncloud/html;

    location = /robots.txt {
        allow all;
        log_not_found off;
        access_log off;
    }

    # The following 2 rules are only needed for the user_webfinger app.
    # Uncomment it if you're planning to use this app.
    #rewrite ^/.well-known/host-meta /public.php?service=host-meta last;
    #rewrite ^/.well-known/host-meta.json /public.php?service=host-meta-json last;

    location = /.well-known/carddav {
        return 301 $scheme://$host/remote.php/dav;
    }
    location = /.well-known/caldav {
        return 301 $scheme://$host/remote.php/dav;
    }

    location /.well-known/acme-challenge { }

    # set max upload size
    client_max_body_size 512M;
    fastcgi_buffers 64 4K;

    # Disable gzip to avoid the removal of the ETag header
    gzip off;

    # Uncomment if your server is build with the ngx_pagespeed module
    # This module is currently not supported.
    #pagespeed off;

    error_page 403 /core/templates/403.php;
    error_page 404 /core/templates/404.php;

    location / {
        rewrite ^ /index.php$uri;
    }

    location ~ ^/(?:build|tests|config|lib|3rdparty|templates|data)/ {
        return 404;
    }
    location ~ ^/(?:\.|autotest|occ|issue|indie|db_|console) {
        return 404;
    }

    location ~ ^/(?:index|remote|public|cron|core/ajax/update|status|ocs/v[12]|updater/.+|ocs-provider/.+|core/templates/40[34])\.php(?:$|/) {
        fastcgi_split_path_info ^(.+\.php)(/.*)$;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME /var/www/html$fastcgi_script_name;
        fastcgi_param PATH_INFO $fastcgi_path_info;
        fastcgi_param HTTPS on;
        fastcgi_param modHeadersAvailable true; #Avoid sending the security headers twice
        fastcgi_param front_controller_active true;
        fastcgi_pass php-handler;
        fastcgi_intercept_errors on;
        fastcgi_request_buffering off; #Available since nginx 1.7.11
    }

    location ~ ^/(?:updater|ocs-provider)(?:$|/) {
        try_files $uri $uri/ =404;
        index index.php;
    }

    # Adding the cache control header for js and css files
    # Make sure it is BELOW the PHP block
    location ~* \.(?:css|js)$ {
        try_files $uri /index.php$uri$is_args$args;
        add_header Cache-Control "public, max-age=7200";
        # Add headers to serve security related headers (It is intended to have those duplicated to the ones above)
        # Before enabling Strict-Transport-Security headers please read into this topic first.
        #add_header Strict-Transport-Security "max-age=15552000; includeSubDomains";
        add_header X-Content-Type-Options nosniff;
        add_header X-Frame-Options "SAMEORIGIN";
        add_header X-XSS-Protection "1; mode=block";
        add_header X-Robots-Tag none;
        add_header X-Download-Options noopen;
        add_header X-Permitted-Cross-Domain-Policies none;
        # Optional: Don't log access to assets
        access_log off;
    }

    location ~* \.(?:svg|gif|png|html|ttf|woff|ico|jpg|jpeg)$ {
        try_files $uri /index.php$uri$is_args$args;
        # Optional: Don't log access to other assets
        access_log off;
    }
}

在官方提供的配置的基础上，我做出了一些改变，除了证书和域名部分是一定要跟你的实际情况一致之外，还有如下改变：

root这一行变成root /home/hfpp2012/owncloud/html;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;变成了fastcgi_param SCRIPT_FILENAME /var/www/html$fastcgi_script_name;

最后一个改变是为了解决一个 nginx 的报错问题而变的。我参考这篇文章进行了解决：

除此之外，有一个地方值得注意，如果不使用 https 的话，除了改变 433 端口为 80 端口一些必要的改变，还需要把下面一行注释掉：
