我正在尝试用xampp升级mysql。php版本=>5.6.3旧版mysql版本=>5.6.21需要升级=>5.7.22（仅在5.7系列中提供下载）
我按照以下步骤升级：

Download latest MySQL but download the zip file not the MSI
Unzip the zip file to a location.
Shutdown Mysql process (no need to remove service) from XAMPP control panel.
Go to XAMPP folder, rename mysql folder to mysql_old
Copy the new unzipped mysql folder to XAMPP folder, in it delete the data folder.
Copy over the data folder from the mysql_old to the new mysql folder.
Copy over the my.ini file under mysql_old/bin to mysql/bin.
Copy over other ini and executable files from mysql_old root folder to mysql (XAMPP ini files, my-huge.ini, my-small.ini, etc..). in my case i copied my-default.ini
Run mysql process from XAMPP control panel. Should work. (You may need
to kill XAMPP first).-->Here I struck out and facing mysql shutdown error.
(OPTIONAL) Run mysql/bin/mysql_upgrade.exe -u USERNAME -p to update tables in the local databases that may have problems due to the version change.

我在我的.ini文件中尝试了1.change port as 330733068111，正如其他人建议的那样。2.进入mysql/data/directory删除ibdata1&ib\u logfile*（ib\u logfile0，ib\u logfile1，ib\u logfile101）文件重启xampp服务器
mysql\u error.log显示如下：2018-05-04t06:31:04.062353z 0[注]c:\mysql upgradexampp\sm3\xampp\mysql\bin\mysqld.exe（mysqld 5.7.22）作为进程9428启动。。。
我以管理员身份运行xampp控制面板，但它仍然显示

Error: MySQL shutdown unexpectedly. 
[mysql] This may be due to a blocked port, missing dependencies,  
[mysql] improper privileges, a crash, or a shutdown by another method. 
[mysql] Press the Logs button to view error logs and check 
[mysql] the Windows Event Viewer for more clues 
[mysql] If you need more help, copy and post this 
[mysql] entire log window on the forums

在命令提示符下，我得到以下错误：error\mysql\bin>mysql-u root-p enter password:error 2003（hy000）：无法连接到“localhost”上的mysql服务器（10061）
请有人给个建议解决。谢谢
