編譯安裝Nginx以及配置運行Drupal 8，實現上傳進度功能

這篇文章的目的是在編譯安裝Nginx的同時，安裝upload和uploadprogress模塊，以及運行Drupal 8所須要的配置。
因爲使用的是Raspberry pi 3B，因此係統用的Raspbian，Debian/Ubuntu應該也是差很少的。

下載Nginx以及相關模塊

下載Nginx以及PCRE模塊並解壓。
進入解壓後的Nginx目錄，執行命令：

./configure --prefix=/etc/nginx --with-pcre=/tmp/pcre-8.39 --sbin-path=/usr/sbin/nginx --with-http_ssl_module --add-module=/mnt/sources/nginx-upload-module --add-module=/mnt/sources/nginx-upload-progress-module

第一個參數是Nginx安裝位置，第二個參數是PCRE源文件位置，第三個參數是Nginx啓動的位置。
接着執行 make && make install，便可完成編譯安裝。

Drupal 8運行須要的配置

首先須要在nginx.conf的http上下文裏增長一條：

upload_progress proxied 1m;

這條是表示每上傳1M就更新進度信息。

接下來就是Drupal網站的配置：

server {
    server_name d8.local.dev;
    root /mnt/apps/d8;
    client_max_body_size 1024m;
    client_body_buffer_size 2048k;

    # 這個地址是用來獲取進度信息，proxied是http裏配置的信息。
    location ^~ /progress {
        report_uploads proxied;
    }

    location = /favicon.ico {
        log_not_found off;
        access_log off;
    }

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

    # Very rarely should these ever be accessed outside of your lan
    location ~* \.(txt|log)$ {
        allow 192.168.0.0/16;
        deny all;
    }

    location ~ \..*/.*\.php$ {
        return 403;
    }

    location ~ ^/sites/.*/private/ {
        return 403;
    }

    # Allow "Well-Known URIs" as per RFC 5785
    location ~* ^/.well-known/ {
        allow all;
    }

    location ~ (^|/)\. {
        return 403;
    }

    location / {
    # 若是是自定義字段上傳的文件，就交由下面的代碼處理
    if ($query_string ~ "X-Progress-ID=\d+"){
        rewrite ^(.*)$ /upload;
    }    
        try_files $uri /index.php?$query_string; # For Drupal >= 7
    }

    location /upload {
        # 文件上傳成功後，處理文件的頁面。index.php是Drupal的入口文件
        upload_pass /index.php;
        # 是否附帶QueryString參數
        upload_pass_args on;
        # 臨時存放文件的目錄
        upload_store /tmp/nginx_upload;
        # 存放上傳狀態的目錄，用於斷點續傳
        upload_state_store /tmp/nginx_state;
        # 臨時目錄的權限
        upload_store_access user:rw group:rw all:rw;
        # 提交到後臺的字段名
        set $upload_field_name "tmp_file";
        # 文件名
        upload_set_form_field $upload_field_name.name "$upload_file_name";
        # 文件類型
        upload_set_form_field $upload_field_name.content_type "$upload_content_type";
        # 臨時路徑
        upload_set_form_field $upload_field_name.path "$upload_tmp_path";
        # 文件MD5信息
        upload_aggregate_form_field "$upload_field_name.md5" "$upload_file_md5";
        # 文件大小
        upload_aggregate_form_field "$upload_field_name.size" "$upload_file_size";
        # 原樣提交到後臺的表單字段，這裏表示全部字段都提交給PHP
        upload_pass_form_field "^.*$";
        upload_cleanup 400 404 499 500-505;
    }

    # Don't allow direct access to PHP files in the vendor directory.
    location ~ /vendor/.*\.php$ {
        deny all;
        return 404;
    }

    location ~ '\.php$|^/update.php' {
        fastcgi_split_path_info ^(.+?\.php)(|/.*)$;
        include fastcgi_params;
        fastcgi_param HTTP_PROXY "";
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_param PATH_INFO $fastcgi_path_info;
        fastcgi_param QUERY_STRING $query_string;
        fastcgi_intercept_errors on;
        # PHP 7 socket location.
        fastcgi_pass 127.0.0.1:9090;

    track_uploads proxied 60s;
    }

    location ~ ^/sites/.*/files/styles/ { # For Drupal >= 7
        try_files $uri @rewrite;
    }

    # Handle private files through Drupal. Private file's path can come
    # with a language prefix.
    location ~ ^(/[a-z\-]+)?/system/files/ { # For Drupal >= 7
        try_files $uri /index.php?$query_string;
    }

    location ~* \.(js|css|png|jpg|jpeg|gif|ico)$ {
        expires max;
        log_not_found off;
    }
}
