আমি করেছি systemd-unit
আমার সিস্টেম সক্ষমিত রয়েছে এমন হয়েছে। সমস্যাটি হ'ল, এটি পুনরায় বুট করার পরে পুনরায় আরম্ভ হবে না। এটি দু'টি পরিষেবাতে নির্ভর করে যা উভয়ই প্রত্যাশা অনুযায়ী শুরু হয়েছিল।
পরিষেবাটি পরিচিত, সক্ষম এবং মৃত:

আমি এমন কিছু সংশোধন করেছি যা আমি করিনি বা করলাম না এবং দেখতে পেলাম না কারণ আমি যথেষ্ট পরিমাণে স্কিনিং করছিলাম না। যাইহোক, দুটি অভিন্ন হোস্টের যেটিতে আমি আমার পরিষেবাটি পুনরায় বুট করার পরে সামনে আনার জন্য কনফিগার করেছিলাম, তার মধ্যে একটি কাজ করেছিল এবং অন্যটি এটি না করা পর্যন্ত না করে।
