使用Docker镜像服务来搭建 craft cms 站点

2017-07-07

Docker CraftCMS

Craft CMS 是一个PHP开发的，以内容导向的内容管理系统，号称是让开发者和内容管理人员用起来会觉得很愉快，官方网站在这里：https://craftcms.com/

它的环境主要是依赖PHP的一些扩展包，详情在这里：https://craftcms.com/docs/requirements

作为一个优秀的程序猿，我们当然不会愿意慢慢的手动搭建这些环境，利用Docker的镜像服务，可以很方便的构建出Craft CMS站点，组成如下：

1. 代理服务器用Nginx
2. 运行环境用 php-fpm
3. 数据库用Mysql

# 下载 Craft CMS源码及配置

直接可以从官网上找到最新版本的下载地址，这里以2.6版本为例：

```bash
wget https://download.craftcdn.com/craft/2.6/2.6.2986/Craft-2.6.2986.zip
unzip -d craftwww Craft-2.6.2986.zip
chmod -R 777 craftwww/craft/app
chmod -R 777 craftwww/craft/config
chmod -R 777 craftwww/craft/storage
```

# Nginx 配置：

我们把Nginx的主配置文件和站点的配置文件分开

## Nginx配置文件nginx.conf：

```
user www-data;
worker_processes 4;
pid /run/nginx.pid;

events {
  worker_connections  2048;
  multi_accept on;
  use epoll;
}

http {
  server_tokens off;
  sendfile on;
  tcp_nopush on;
  tcp_nodelay on;
  keepalive_timeout 15;
  types_hash_max_size 2048;
  include /etc/nginx/mime.types;
  default_type application/octet-stream;
  access_log off;
  error_log off;
  gzip on;
  gzip_disable "msie6";
  client_max_body_size 500M;
  include /etc/nginx/conf.d/*.conf;
  include /etc/nginx/sites-available/*;
  open_file_cache max=100;
}

daemon off;
```

## 站点配置文件： www.conf

```
server {
  listen 80 default_server;
  listen [::]:80 default_server ipv6only=on;

  root /var/www/craftwww/public;
  index index.php index.html index.htm;

  location / {
     try_files $uri $uri/ /index.php$is_args$args;
  }

  location ~ \.php$ {
    try_files $uri /index.php =404;
    fastcgi_pass php-upstream;
    fastcgi_index index.php;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    include fastcgi_params;
  }

  location ~ /\.ht {
    deny all;
  }

  # cache.appcache, your document html and data
  location ~* \.(?:manifest|appcache|html?|xml|json)$ {
    expires -1;
    access_log /var/log/nginx/static.log;
  }

  # Feed
  location ~* \.(?:rss|atom)$ {
    expires 1h;
    add_header Cache-Control "public";
  }

  # Media: images, icons, video, audio, HTC
  location ~* \.(?:jpg|jpeg|gif|png|ico|cur|gz|svg|svgz|mp4|ogg|ogv|webm|htc)$ {
    expires 1M;
    access_log off;
    add_header Cache-Control "public";
  }

  # CSS and Javascript
  location ~* \.(?:css|js)$ {
    expires 1y;
    access_log off;
    add_header Cache-Control "public";
  }

  # WebFonts
  location ~* \.(?:ttf|ttc|otf|eot|woff|woff2)$ {
    expires 1M;
    access_log off;
    add_header Cache-Control "public";
  }
}
```

## Nginx的构建文件：Dockerfile

```

    && echo "upstream php-upstream { server php:9000; }" > /etc/nginx/conf.d/upstream.conf

# 启动容器

进入docker目录，运行

  docker-compose up -d -p craftwww

# 建立db

进入 mysql 容器，建立db：

  CREATE DATABASE IF NOT EXISTS craftwww CHARACTER SET utf8 COLLATE utf8_unicode_ci;

# 配置craft cms的db链接

修改 craft/config/db.php文件，配置为 mysql 容器

# 访问站点及配置

上述一切完成之后，访问下面链接会对站点进行初始化：

  http://ip:8001/admin

看到如下界面就说明成功了：
