数据库无法启动，今天无缘无故启动不起来了。
手动尝试了很多的修改，还是无法启动
结果用官方的脚本解决了。
使用方法
在ssh输入：wget -O sql-repair.sh http://download.bt.cn/install/sql-repair.sh && sh sql-repair.sh
运行宝塔检测脚本，然后可以排除错误。一般来说可以启动数据库了。
也可以自己创建一个脚本然后运行，代码如下
#!/bin/bash
PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin:~/bin
export PATH
Mysql_Check(){
if [ ! -f "/www/server/mysql/bin/mysql" ]; then
echo "此服务器并没有安装宝塔mysql！"
exit;
fi
ps -ef |grep /www/server/mysql |grep -v grep > null
if [ $? -ne 1 ]; then
echo "mysql is running! exit;"
exit;
fi
}
