现象描述：
cms内容发布系统上传不了大文件，当上传超过32M文件时就上传不了
提示:无效的文件. 文件尺寸太大。
分析文件上传过程：
browser --> nginx --> php
需要修改 nginx.conf和php.ini
1.nginx.conf新增如下参数，重启无效：
client_max_body_size 512M; client_body_buffer_size 128M;
2.修改php.ini配置，重启php-fpm无效：
/usr/local/php-7.0.12_fpm/lib/php.ini post_max_size = 512M upload_max_filesize = 256M

3.找到上传文件代码所在的目录 /data/www/cms/cmsx.chinasoft.com.wx/httpdocs/public
[root@newcms:/data/www/cms/cmsx.chinasoft.com.wx/httpdocs/public]# grep -ri "无效的文件. 文件尺寸太大" resources/js/libs/ckfinder/core/connector/php/lang/zh-cn.php: ‘203‘ => ‘无效的文件. 文件尺寸太大。‘, resources/js/libs/ckfinder/lang/zh-cn.js: 203 : ‘无效的文件. 文件尺寸太大。‘,
发现使用了 ckfinder 这个富文本插件
经过搜索发现限制在配置文件config.php，修改最大文件问题解决：
[root@newcms:/data/www/cms/cmsx.chinasoft.com.wx/httpdocs/public]# find ./ -name config.php /data/www/cms/cmsx.chinasoft.com.wx/httpdocs/public/resources/js/libs/ckfinder/config.php $config[‘DefaultResourceTypes‘] = ‘‘; $dir_name_1 = preg_replace(‘/.+\/([^\/]*[a-z]+\.[a-z]+)\/.+/‘, ‘$1‘, $baseDir); $config[‘ResourceType‘][] = Array( ‘name‘ => $dir_name_1, // Single quotes not allowed ‘url‘ => $baseUrl, ‘directory‘ => $baseDir, ‘maxSize‘ => "300M", # 修改此处 ‘allowedExtensions‘ => isset( $_GET[‘show_format‘] ) ? $_GET[‘show_format‘] : ‘‘, ‘deniedExtensions‘ => ‘‘); $config[‘AccessControl‘][] = Array( ‘role‘ => ‘*‘, ‘resourceType‘ => $dir_name_1, ‘folder‘ => ‘/‘, ‘folderView‘ => true, ‘folderCreate‘ => true, ‘folderRename‘ => false, ‘folderDelete‘ => true, ‘fileView‘ => true, ‘fileUpload‘ => true, ‘fileRename‘ => true, ‘fileDelete‘ => true); $dir_name_2 = ‘All files list‘; $config[‘ResourceType‘][] = Array( ‘name‘ => $dir_name_2, ‘url‘ => ‘‘, ‘directory‘ => ‘‘, ‘maxSize‘ => "300M", # 修改此处 ‘allowedExtensions‘ => isset( $_GET[‘show_format‘] ) ? $_GET[‘show_format‘] : ‘‘, ‘deniedExtensions‘ => ‘‘);
