问题描述

  • 在将MySQL从8.0.22降级到较旧版本后、Active IQ Unified Manager (UM)安装失败。

Job for mysqld.service failed because the control process exited with error code. See "systemctl status mysqld.service" and "journalctl -xe" for details.

FAILURE: Unable to init MySQL.

error: %pre(netapp-um-9.7-2006081700.x86_64) scriptlet failed, exit status 1
Error in PREIN scriptlet in rpm package netapp-um-9.7-2006081700.x86_64
  Verifying  : netapp-um-9.7-2006081700.x86_64

Failed:
  netapp-um.x86_64 0:9.7-2006081700

  • 检查MySQL服务状态会显示此服务无法启动、并显示错误"无此文件或目录"。

[root@centos]# systemctl status mysqld.service

  • 查看MySQL错误日志(位于 /var/log/mysql/error.log)中的最新条目时、请参见先前的8.0.22安装。在降级版本下、不会创建任何新日志条目。
