درود
بزرگوار برای trace مشکلات mysql باید لاگ mysql بررسی گردد فایل کانفیگ فوق کمکی به حل مشکل شما نخواهد کرد

[AhrimanSefid]

ممنون از راهنماییتون اما کانفیگ رو دست کاری کردم استارت نمی شه دیگه.

[mahdiazarnia]

سیستم عامل چی هست ؟
ابتدا دستورات زیر رو بزنید ببینید جواب میده
service mysql stop
mv /etc/my.cnf /etc/my.cnf.bk
service mysql start

[AhrimanSefid]

بازم ممنونم اما مشکل از :
# INNODB #
innodb-flush-method = O_DIRECT
innodb-log-files-in-group = 2
innodb-log-file-size = 512M
innodb-flush-log-at-trx-commit = 1
innodb-file-per-table = 1
innodb-buffer-pool-size = 20G
حذفش کردم درست شد.
