Centos7 安装 wkhtmltopdf
1、先查看系统是 32 位的还是 64 位的
uname -a
2、通过 composer 安装 wkhtmltopdf
32位:
$ composer require h4cc / wkhtmltopdf-i386 0.12.x
$ composer require h4cc / wkhtmltoimage-i386 0.12.x
64位:
$ composer require h4cc/wkhtmltopdf-amd64 0.12.x
$ composer require h4cc/wkhtmltoimage-amd64 0.12.x
3、接下来将安装好的 wkhtmltopdf 复制到 Linux 系统可执行命令的目录中
cp vendor/h4cc/wkhtmltoimage-amd64/bin/wkhtmltoimage-amd64 /usr/local/bin/
cp vendor/h4cc/wkhtmltopdf-amd64/bin/wkhtmltopdf-amd64 /usr/local/bin/
//并使其可执行：
chmod +x /usr/local/bin/wkhtmltoimage-amd64
chmod +x /usr/local/bin/wkhtmltopdf-amd64
Laravel 安装 snappy
composer require barryvdh/laravel-snappy
配置（可选，Laravel 5.5+ 自动发现、不用管1、2步骤）
1、将 ServiceProvider 添加到 config/app.php 中的 providers 数组中
Barryvdh\Snappy\ServiceProvider::class,
2、将 Facades 添加到 config/app.php 中的 aliases 数组中
'PDF' => Barryvdh\Snappy\Facades\SnappyPdf::class,
'SnappyImage' => Barryvdh\Snappy\Facades\SnappyImage::class,
3、生成配置文件
php artisan vendor:publish --provider="Barryvdh\Snappy\ServiceProvider"
注意：config 文件夹中的 snappy.php 就是其配置文件，binary 指向的就是上面安装的 wkhtml 相关路径.
'pdf' => [
'enabled' => true,
'binary' => env('WKHTML_PDF_BINARY', '/usr/local/bin/wkhtmltopdf-amd64'),
'timeout' => false,
'options' => [],
'env' => [],
],
'image' => [
'enabled' => true,
'binary' => env('WKHTML_IMG_BINARY', '/usr/local/bin/wkhtmltoimage-amd64'),
'timeout' => false,
'options' => [],
'env' => [],
],
