Laravel 5 - skip migrations
提问by Erhnam
I have migrated an existing Laravel 5 application and database. Only no migrations table was there yet, so I created this with the following command:
我已经迁移了现有的 Laravel 5 应用程序和数据库。目前还没有迁移表，所以我使用以下命令创建了它：
php artisan migrate:install
Inside the database migration folders three files exist (2015_12_08_134409_create_tables_script.php, 2015_12_08_134410_create_foreign.php, 2015_12_08_134411_create_index.php)
在数据库迁移文件夹中存在三个文件（2015_12_08_134409_create_tables_script.php、2015_12_08_134410_create_foreign.php、2015_12_08_134411_create_index.php）
When using 'php artisan migrate' the scripts inside the migrations folder are executed again. This is what I want to avoid. Is it possible to insert records in Laravel's migrations table, so these scripts will be skipped and new scripts will be picked up once 'php artisan migrate' is executed again?
使用“php artisan migrate”时，迁移文件夹中的脚本将再次执行。这是我想要避免的。是否可以在 Laravel 的迁移表中插入记录，因此一旦 'php artisan migrate' 再次执行，这些脚本将被跳过并拾取新脚本？

Once you have the migration table created, insert these records:
创建迁移表后，插入以下记录：
insert into migrations(migration, batch) values('2015_12_08_134409_create_tables_script',1);
insert into migrations(migration, batch) values('2015_12_08_134410_create_foreign',1);
insert into migrations(migration, batch) values('2015_12_08_134411_create_index',1);
So artisan will understand those migrations as 'executed'
所以工匠会将这些迁移理解为“已执行”

Another way is just create a folder under database/migrationsto put you want skip migrations, this method works for both files that have been migrated or not yet migrated.
另一种方法是在下面创建一个文件夹database/migrations来放置您想要跳过的迁移，此方法适用于已迁移或尚未迁移的文件。
# Execute commands in laravel project root folder
mkdir database/migrations/ignored
mv database/migrations/2018_08_14_000000_should_ignore_migration.php \
database/migrations/ignored/
# Check migration has been skipped
php artisan migrate:status

This Artisan CLI extension commandis support single command to migrate specific files on Laravel 5.4 or later:
这个Artisan CLI 扩展命令支持单个命令在 Laravel 5.4 或更高版本上迁移特定文件：
# Install extension
composer require caloskao/migrate-specific
# Migrate
php artisan migrate:specific /path/to/migration_file.php
