Cara Memperbaiki Pesan MySQLTUNER [!!] Attempted to use login credentials from Debian maintenance account, but they failed.

MySQLTuner

MySQLTuner adalah skrip yang ditulis dalam Perl yang membantu kita menganalisis dan mengkonfigurasi server database MySQL/MariaDB untuk mendapatkan peningkatan kinerja, stabilitas, dan lingkungan server yang seimbang.

Namun pada kondisi tertentu kita tidak bisa mengeksekusi perintah mysqltuner. Error tersebut paling sering terjadi pada sistem Debian/Ubuntu, dimana kita benar-benar tidak dapat menjalankan perintah mysqltuner.

Pesan error yang paling umum saat kita menjalankan mysqltuner adalah sebagai berikut:

root@dev:~# mysqltuner
 >>  MySQLTuner 1.7.17 - Major Hayden 
 >>  Bug reports, feature requests, and downloads at http://mysqltuner.com/
 >>  Run with '--help' for additional options and output filtering

[--] Skipped version check for MySQLTuner script
[!!] Attempted to use login credentials from Debian maintenance account, but they failed.

Bagaimana memperbaikinya?

1. Nah, untuk memperbaiki kesalahan ini pertama-tama kita perlu mendownload mysqltuner.pl dengan perintah sederhana.

$ wget http://mysqltuner.pl/ -O mysqltuner.pl --no-check-certificate

2. Kemudian silahkan atur izin/permission pada file mysqltuner.pl yang baru saja kita download.

$ chmod +x mysqltuner.pl

3. Terakhir, untuk memperbaiki script mysqltuner yang error, Anda bisa menjalankan mysqltuner dengan perintah berikut.

$ perl mysqltuner.pl --user root --pass 'passwordroot'

NOTE: Ubah ‘passwordroot’ dengan kata sandi root MySQL/MariaDB Anda

Anda dapat menggunakan perintah di atas setiap kali Anda ingin menjalankan mysqltuner, daripada hanya menjalankan mysqltuner atau perintah ./mysqltuner.pl.

root@dev:~# perl mysqltuner.pl --user root --pass 'passwordroot'

    Performance schema should be activated for better diagnostics
    Consider installing Sys schema from https://github.com/FromDual/mariadb-sys for MariaDB
    Be careful, increasing innodb_log_file_size / innodb_log_files_in_group means higher crash recovery mean time
Variables to adjust:
    table_open_cache (> 2000)
    table_definition_cache (400) > 476 or -1 (autosizing if supported)
    innodb_log_buffer_size (> 16M)
