安装composer，网址https://pkg.phpcomposer.com/#how-to-install-composer

命令：

php -r "copy('https://install.phpcomposer.com/installer', 'composer-setup.php');"

php composer-setup.php

php -r "unlink('composer-setup.php');"

 root@3766fc8edd88:/usr/share/nginx/www# composer create-project laravel/laravel  laravel "5.4.*"

开始安装的时候报错：

 [InvalidArgumentException]
  Could not find package laravel/laravel with version 5.4.*.

换一个镜像就行了：

参考一下这个：https://blog.csdn.net/weixin_42014858/article/details/113312698

composer config -g repo.packagist composer https://packagist.org

 

有报错了：

Failed to download laravel/laravel from dist: The zip extension and unzip command are both missing, skipping.
Your command-line PHP is using multiple ini files. Run `php --ini` to show them.
    Now trying to download from source


  [RuntimeException]
  git was not found in your PATH, skipping source download

 

出现这个问题是由于环境中缺少zip跟unzip

依次进行如下指令
apt --fix-broken install
apt-get update
apt-get upgrade

apt-get install zip

然后就可以了：

然后又报错：

The stream or file "/usr/share/nginx/www/laravel/storage/logs/laravel.log" could not be opened in append mode: failed to open stream: Permission denied

权限问题：chmod -R 777 storage

我的加完权限就可以了！

改一下根目录下的.env文件，执行 php artisan migrate:install

创建控制器：php artisan make:controller PostController
