出現需要翻牆情況

提示：The "https://packagist.org/packages.json" file could not be downloaded: failed to open stream: Connection refused

以上所有問題的原因都是映象的問題，國外映象載入速度慢，那麼換個映象，下面載入阿里雲的映象，執行：

composer config -g repo.packagist composer https://mirrors.aliyun.com/composer/

------------------------------------------------------------------------------------------------

composer create-project laravel/laravel=5.7.* laravel --prefer-dist

cd /home/wwwroot/laravel

執行composer update

錯誤提示：

Problem 1
- league/flysystem 1.0.69 requires ext-fileinfo * -> the requested PHP extension fileinfo is missing from your system.

缺擴充套件Fileinfo解決方法：

lnmp.conf配置檔案內容看下有沒有Enable_PHP_Fileinfo='y'這樣的配置

------------------------------------------------------------------------------------------------

rewrite URL 方案：

/usr/local/nginx/conf/vhost/web.com.conf

除錯錯誤：

index.php

ini_set("display_errors", "On");
error_reporting(E_ALL | E_STRICT);

資料庫認證錯誤的解決方案：

---------------解決by lin-----------------

laravel要刪除open_basedir方法：

/usr/local/nginx/conf/fastcgi.conf

最後三行：

fastcgi_param PHP_ADMIN_VALUE "open_basedir=NULL";
# fastcgi_param PHP_ADMIN_VALUE "open_basedir=$document_root/:/tmp/:/proc/";
# fastcgi_param PHP_ADMIN_VALUE "open_basedir=$document_root/:/tmp/:/proc/";
