有手动备份的那种吗？
不想要命令行的。

楼主这代码可以商用嘛？

非常棒~ 不过还有好多地方没有需要完善，楼主任重道远。已关注。

我执行命令行：php ./yii install/install 的时候发现报错，然后就没管，直接下一个步骤了，参照 doc 目录下的Nginx和Apache配置文件，配置服务器，并设置hosts文件。 这个步骤没什么可说的，我是在本地进行测试的，xampp, 按照最后一种方式配的。需要注意的是如果命令行执行失败，估计是根目录不会自动生成 .env 文件。反正我没找到。然后直接复制了一份.env.example 为 .env 对照着在里面把自己的数据库和路径写了一下就能查看啦（windows 上新建 .env的时候会告诉你需要填文件名，蛋疼的windows 后缀模式。。。 你可以直接新建 .env. 然后保存，自动变成 .env）。

就到这里吧，期待楼主为我们带来更多惊喜。加油~~
