由于服务器不是纯净环境!所以重装宝塔会莫名的mysql不能启动,查询所有贴都没有解释;最后终于在‘https://felicoz.com/2017/05/bt-unable-to-start-mysql/’这里寻找到解决答案!
宝塔 BT – MySQL 5.6 无法启动2017年5月3日更新: 宝塔 V4.0 已修复该问题, 未来会自动修复 my.cnf 档案 — 宝塔 v3.9 出现了 MySQL 的问题, 部分MySQL版本5.6会自动关闭并且无法重启. 主要的问题在于 MySQL 的配置档案被清理变成空白档, 具体原因不知道. 需要修复文件 /etc/my.cnf. 麻烦的方法是在其他空间架设同样的宝塔然后复制 /etc/my.cnf 的设置内容. 我刚好有另一个面板也使用 MySQL 5.6 所以可以直接复制过去. 这是 my.cnf 的设置内容, 你可以试试: - [client]
