از طريق SSH چطور ميشه براي يك دامنه خاص DB درست كرد
من به سرور لاگين ميشم
بعدبه mysql لاگين ميشم

مثلا مي خوام برا دامين ali.com ديتا بيس درست كنم
چطوري؟
لطفا كاملا ابتدايي و مرحله به مرحله توضيح بديد.
سوال دوم همون جوري كه برا backup گيري اين اسكريپت هست
/scripts/pkgacct
برا درست كردن يك يوزر هم اسكريپت هست ؟
كسي مرجعي داره در مورد اين فولدر /scripts كه بدونيم هر چيزي چيه ؟
ممنون
دیتابیس کاری به دامین نداره شما باید دیتابیس بسازید و یه یوزر که به اون دیتابیس دسترسی داشته باشه
(می شه یه دیتابیس باشه دوتا سایت یا دامین یا یوزر mysql ازش استفاده کنن و بالعکس)
