考研去了，几个月没管项目，今天一打开数据库挂了，各种问号，按照网上一些步骤执行命令却把mysql彻底搞崩了，突然料到可能是因为我阿里云装的宝塔面板还有一堆其他东西导致相同的命令别人行我却不行，无奈，干脆写一个从头到尾自动删除和重装mysql的脚本，最好是能一执行完就能直接navicat连接的那种！先直接看效果：（彻底删除mysql的部分截图）（自动配置mysql的部分截图） (对，然后就连接成功了) shell脚本代码如下：当然你也可以直接在github上下载最新版本: 点这里 #删除mysql及其相关依赖包 echo "正在删除mysql及其相关依赖包..." rpm -qa | grep -i mysql | xargs rpm -e --nodeps echo "Done." #删除mysql所涉及的安装目录 echo "正在删除mysql所涉及的安装目录..." whereis mysql | xargs rm -rf echo "Done." #删除所有和mysql相关的目录 echo "正在删除所有和mysql相关的目录..." find / -name mysql | xargs rm -rf echo "Done." #删除所有配置文件 echo "正在删除所有配置文件..." find / -name my.cnf* | xargs rm -rf echo
