# ThinkPHP5实现安装程序 **install.php** - `public/install.php` > 首先在`thinkphp5`框架下的入口文件`index.php`,加入如下判断 ``` // 1.判断当前 php 版本 if (version_compare(PHP_VERSION,'5.6','<')) die('require PHP > 5.6'); // 判断是否安装 后面的地址随便你,你愿意扔那里就扔哪里 if (!is_file(APP_PATH . 'admin/command/Install/install.lock')) { // 这个地址也是你的install.php 文件在那里就指向那哪里 header("location:./install.php"); exit; } ``` > 其次在`install.php`进行详细代码 - 定义站点名称 ```php $sitename = "Your sitename" ``` - 定义报错信息 ``` $errInfo = ''; ``` - 定义目录分隔符 ``` define('DS', DIRECTORY_SEPARATOR) ``` - 定义根目录 ``` define('ROOT_PATH', __DIR__ . DS . '..' . DS); ``` - 定义应用目录 ``` define('APP_PATH', ROOT_PATH . 'application' . DS); ``` - 定义安装包目录(你的在哪里就定义在哪里) ``` define('INSTALL_PATH', APP_PATH . 'admin' . DS . 'command' . DS . 'Install' . DS); ``` - 判断文件是否有写的权限 ``` function is_really_writable($file) { if (DIRECTORY_SEPARATOR == '/' AND @ ini_get("safe_mode") == false) { return is_writable($file); } if (!is_file($file) OR ($fp = @fopen($file, "r+")) === false) { return false; } fclose($fp); return true; } ``` - 检测关键目录是否存在 ``` $checkDirs = [ 'thinkphp', 'vendor', 'public' . DS . 'assets' . DS . 'libs' ]; ``` - 缓存目录 ``` $runtimeDir = APP_PATH . 'runtime'; ``` - 数据库配置文件 - thinkphp 5.0 ``` $dbConfigFile = APP_PATH . 'database.php'; ``` - thinkphp 5.1 config目录下的 `database.php`配置文件 ``` $dbConfigFile = 'config' . 'database.php'; ``` - 锁定的文件 ``` // 锁定的文件 $lockFile = INSTALL_PATH . 'install.lock'; if (is_file($lockFile)) { $errInfo = "当前已经安装{$sitename},如果需要重新安装,请手动移除application/admin/command/Install/install.lock文件"; } else { if (version_compare(PHP_VERSION, '5.5.0', '<')) { $errInfo = "当前版本(" .
