修改配置

WordPress中许多不必要的功能可以通过修改配置文件的方式关闭。注意：在进行相关操作前务必备份好源文件！

  • 在 wp-config.php文件后添加下列内容
//WordPress自定义优化项。
define('WP_DEBUG', false);  //关闭DEBUG
define('AUTOSAVE_INTERVAL', 86400);  //关闭自动保存
define('WP_POST_REVISIONS', false);  //关闭修订
define('DISALLOW_FILE_EDIT', true);  //关闭文件修改
define('FS_CHMOD_DIR', (0755 & ~ umask()));  //目录权限755
define('FS_CHMOD_FILE', (0644 & ~ umask()));  //文件权限644
 
//禁止更新（不建议）
//define('AUTOMATIC_UPDATER_DISABLED', true);
//define('WP_AUTO_UPDATE_CORE', false);
  • 在当前主题目录中function.php后添加下列内容
//WordPress主题 functions.php 优化项
