我正在尝试在xamp中安装upgrade mysql。我使用的是laravel，它需要mariaDB v10.2.2。所以我从mariaDB website中下载了latest msi package。现在我按照以下几点安装相同的：

• 将MySQL安装到C：\TEMP。
• 将旧的安装文件夹设置为mysql_old。
• 将以下文件夹“bin，include，lib，share，support-files”复制到xamp\mysql\ folder。我没有复制数据文件夹
• 已将my.ini文件从旧安装复制到xamp\mysql\bin\文件夹中的新安装
• 已将旧数据文件夹复制到新的mysql文件夹

现在，在这样做后，我试图从控制面板启动MySQL，并显示以下错误：

现在，在检查错误日志时，我发现：

# Example MySQL config file for small systems.

# 

# This is for a system with little memory (<= 64M) where MySQL is only used

# from time to time and it's important that the mysqld daemon

# doesn't use much resources.

# 

# You can copy this file to

# F:/xamp/mysql/bin/my.cnf to set global options,

# mysql-data-dir/my.cnf to set server-specific options (in this

# installation this directory is F:/xamp/mysql/data) or

# ~/.my.cnf to set user-specific options.

# 

# In this file, you can use all long options that a program supports.

# If you want to know which options a program supports, run the program

# with the "--help" option.

# The following options will be passed to all MySQL clients

[client] 

# password       = your_password

# Replication Slave (comment out master section to use this)

# 

# To configure this host as a replication slave, you can choose between

# two methods :

# 

# 1) Use the CHANGE MASTER TO command (fully described in our manual) -

# the syntax is:

# 

# CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,

# MASTER_USER=<user>, MASTER_PASSWORD=<password> ;

# 

# where you replace <host>, <user>, <password> by quoted strings and

# <port> by the master's port number (3306 by default).

# 

# Example:

# 

# CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,

# MASTER_USER='joe', MASTER_PASSWORD='secret';

# 

# OR

# 

# 2) Set the variables below. However, in case you choose this method, then

# start replication for the first time (even unsuccessfully, for example

# if you mistyped the password in master-password and the slave fails to

# connect), the slave will create a master.info file, and any later

# change in this file to the variables' values below will be ignored and

# overridden by the content of the master.info file, unless you shutdown

# the slave server, delete master.info and restart the slaver server.

# For that reason, you may want to leave the lines below untouched

# (commented) and instead use CHANGE MASTER TO (see above)

# 

# required unique id between 2 and 2^32 - 1

# (and different from the master)

# defaults to 2 if master-host is set

# but will not function as a slave if omitted

# server-id       = 2

# 

# The replication master for this slave - required

# master-host     =   <hostname>

# 

# The username the slave will use for authentication when connecting

# to the master - required

# master-user     =   <username>

# 

# The password the slave will authenticate with when connecting to

# the master - required

# master-password =   <password>

# 

# The port the master is listening on.

# optional - defaults to 3306

# master-port     =  <port>

# 

# binary logging - not required for slaves, but recommended
