After my new production server installation, I discovered I couldn’t run migrations: $ ./yii migrate/up bash: ./yii: Permission denied Adding execution permissions to ./yii resolved the problem: $ chmod +x ./yii deploy@apps:/var/www/mp$ ./yii migrate/up Yii Migration Tool (based on Yii v2.0.8) No new migrations found. Your system is up-to-date. Found via this comment.
