@[TOC](Mysql 启动报错并成功解决：Starting MySQL.2023-11-16T06:24:39.857506Z mysqld_safe error: log-error set to ‘/var/log/mariadb/mariadb.log’,however file don’t exists. Create writable for user ‘mysql’. The server quit without updating PID file (/var/lib/mysql/y[FAILED]d))
当我们启动MySQL数据库时，一直报错。。。。。。。。。。。。
在网上找了很多种方法都无法解决，终于…皇天不负有心人，终于让我嘚住啦！！！只需改一个文件就得吃啦！！！！！
查看mysql.server文件是否一致vim /usr/local/mysql/support-files/mysql.server
文章来源：https://www.toymoban.com/news/detail-772742.html
//复制文件并赋予权限
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld && chmod 755 /etc/init.d/mysqld
进入/etc/my.cnf，把里面的内容全部删除后直接全部复制下面内容进去，保存并退出，（前提是你信我哈，不太相信就提前cp my.cnf文件）
// 配置my.cnf
vim /etc/my.cnf
//删除原有的全部内容，然后复制下面内容，:wq保存并退出

最后我们就来验证一下是否可以成功启动MySQL数据库并不会报错
