আমি একটি রেডিস সার্ভার ব্যবহার করে এমন একটি প্রোগ্রামকে ডিগ্রো করতে / পরীক্ষা করতে চাই যাতে আমি সার্ভারটি চালু করার সুবিধা অর্জনের জন্য একটি ব্যবহারকারী পরিষেবাতে পরিণত করার সিদ্ধান্ত নিয়েছিলাম। আমাকে বিরক্ত করার বিষয়টি হ'ল আমি পরিষেবাটি শুরু করতে বা বন্ধ করতে পারি তবে এটি সক্ষম / অক্ষম করতে পারছি না।
আমি যে ত্রুটি পেয়েছি তা হ'ল:
