ฉันพยายามเริ่ม MySQL ใหม่หลังจากบันทึกสคริปต์ ข้อผิดพลาดระบุ
Job for mysql.service failed because the control process exited with error code. See "systemctl status mysql.service" and "journalctl -xe" for details.
เมื่อทำงานsystemctl status mysql.service
นี่คือสิ่งที่ฉันได้รับ:
Loaded: loaded (/lib/systemd/system/mysql.service; enabled; vendor preset: enabled)

ฉันไม่แน่ใจว่าจะเริ่มแก้ไขตรงไหน
นี่คือสคริปต์ที่ฉันบันทึกไว้ก่อนที่จะรีสตาร์ท mysql:
[mysqld]
innodb_rollback_on_timeout=1
innodb_lock_wait_timeout=600
max_connections=350
log-bin=mysql-bin
binlog-format = 'ROW'
