在Laravel 5.4上使用php artisan make:auth迁移错误
[Illuminate\Database\QueryException] SQLSTATE[42000]: Syntax error or access violation: 1071 Specified key was too long; max key length is 767 bytes (SQL: alter tabl e users add unique users_email_unique(email)) [PDOException] SQLSTATE[42000]: Syntax error or access violation: 1071 Specified key was too long; max key length is 767 bytes
当前回答
对于这个错误，我找到了两个解决方案
选项1:
打开database/migrations文件夹下的user和password_reset表
只需要改变邮件的长度:
$table->string('email',191)->unique();
选项2:
打开app/Providers/AppServiceProvider.php文件，在boot()方法中设置一个默认字符串长度:
use Illuminate\Support\Facades\Schema;
public function boot()
{
Schema::defaultStringLength(191);
}
其他回答
只要在/etc/mysql/mariadb.conf.d/50-server.cnf或其他配置文件中写几行:
innodb-file-format=barracuda
innodb-file-per-table=ON
innodb-large-prefix=ON
innodb_default_row_format = 'DYNAMIC'
和sudo服务mysql重启
https://stackoverflow.com/a/57465235/778234
查看文档:https://dev.mysql.com/doc/refman/5.6/en/innodb-row-format.html
尝试使用默认字符串长度125 (MySQL 8.0)。
defaultStringLength (125)
如前所述，我们在App/Providers中添加到AppServiceProvider.php
use Illuminate\Support\Facades\Schema; // add this
/**
* Bootstrap any application services.
*
* @return void
*/
public function boot()
{
Schema::defaultStringLength(191); // also this line
}
你可以在下面的链接中看到更多细节(搜索“索引长度& MySQL / MariaDB”) https://laravel.com/docs/5.5/migrations
BUT WELL THAT's not what I published all about! the thing is even when doing the above you will likely to get another error (that's when you run php artisan migrate command and because of the problem of the length, the operation will likely stuck in the middle. solution is below, and the user table is likely created without the rest or not totally correctly) we need to roll back. the default roll back will not work. because the operation of migration didn't like finish. you need to delete the new created tables in the database manually.
我们可以这样做使用修补器如下所示:
L:\todos> php artisan tinker
Psy Shell v0.8.15 (PHP 7.1.10 — cli) by Justin Hileman
>>> Schema::drop('users')
=> null
我自己有一个问题与用户表。
之后你就可以开始了
PHP artisan migrate:回滚
PHP工匠迁移
首先删除本地主机中数据库的所有表
更改Laravel默认数据库(utf8mb4)在config/database.php文件中的属性为:
'charset' => 'utf8'， 'collation' => 'utf8_unicode_ci'，
之后 更改我的本地数据库属性utf8_unicode_ci。 PHP工匠迁移 没关系。
将我的本地数据库服务器类型从“mariadb”更改为“mysql”，无需编辑任何Laravel文件就可以解决这个问题。
我按照本教程更改了我的db服务器类型:https://odan.github.io/2017/08/13/xampp-replacing-mariadb-with-mysql.html
