安装laravel-admin过程

安装laravel5.5

composer create-project --prefer-dist laravel/laravel blog "5.5.*"

首先确保安装好了laravel，并且数据库连接设置正确

composer require encore/laravel-admin:1.*

然后运行下面的命令来发布资源

php artisan vendor:publish --provider="EncoreAdminAdminServiceProvider"

接下来运行 php artisan admin:install

D:wwwrootwww.test.com>php artisan admin:install
Migration table created successfully.

In Connection.php line 664:

  SQLSTATE[42000]: Syntax error or access violation: 1071 Specified key was too long; max key length is 1000 bytes (S
  QL: alter table `users` add unique `users_email_unique`(`email`))


In Connection.php line 458:

  SQLSTATE[42000]: Syntax error or access violation: 1071 Specified key was too long; max key length is 1000 bytes

报错了，laravel 5.4 改变了默认的数据库字符集，现在utf8mb4包括存储emojis支持。如果你运行MySQL v5.7.7或者更高版本，则不需要做任何事情。

当你试着在一些MariaDB或者一些老版本的的MySQL上运行 migrations 命令时，就会遇到这个错误，改正方法：
在appProvidersAppServiceProvider.php添加默认值

use IlluminateSupportFacadesSchema; //add fixed sql
 public function boot()
    {
        Schema::defaultStringLength(191); //add fixed sql
    }

改完之后这里需要注意将之前得两张表删除，否则就会报这个错

In Connection.php line 664:

  SQLSTATE[42S01]: Base table or view already exists: 1050 Table 'users' alre
  ady exists (SQL: create table `users` (`id` int unsigned not null auto_incr
  ement primary key, `name` varchar(191) not null, `email` varchar(191) not n
  ull, `password` varchar(191) not null, `remember_token` varchar(100) null,
  `created_at` timestamp null, `updated_at` timestamp null) default character

In PDOStatement.php line 119:

  SQLSTATE[42S01]: Base table or view already exists: 1050 Table 'users' alre
  ady exists


In PDOStatement.php line 117:

  SQLSTATE[42S01]: Base table or view already exists: 1050 Table 'users' alre
  ady exists

之后再来执行php artisan admin:install

Migration table created successfully.
