Pengaturan kami:
- Master: MariaDB 10.0.21
- Budak: MariaDB 10.0.17
Replikasi bekerja dengan baik sampai saat ini pada titik mana DB budak harus dipulihkan dari dump. Saya melakukan semua langkah yang diperlukan: Dump DB master, transfer dump ke slave, drop DB lama, jalankan dump untuk mengembalikan DB, jalankan CHANGE MASTER
perintah yang sesuai , dan akhirnya START SLAVE
.
Saya menerima kesalahan:
Got fatal error 1236 from master when reading data from binary log: 'Could not find first log file name in binary log index file'
File log pertama yang dibutuhkan budak dari master adalah mysql-bin.000289
. Saya dapat melihat bahwa ini ada pada master:
Saya juga dapat melihat bahwa indeks log biner pada master tampaknya memiliki entri untuk file log ini:
Replikasi masih tidak berfungsi - saya terus mendapatkan kesalahan yang sama. Saya kehabisan ide - apa yang harus saya periksa selanjutnya?
Diperbarui: Output SHOW SLAVE STATUS\G
