4.???????修改端口和字符集：在安装目录下找到my.ini配置文件打开编辑，把端口改成3306（注：安装的时候默认就是3306），并且把服务器的字符集改成utf8(注：注意版本)，如下：

# The following options will be passed to all MySQL clients

[client]

#password?? = your_password

port?????????????? = 3306

socket?????????? = /tmp/mysql.sock

default-character-set=gbk

?

# Here follows entries for some specific programs

?

# The MySQL server

[mysqld]

port?????????????? = 3306

socket?????????? = /tmp/mysql.sock

skip-locking

key_buffer_size = 256M

max_allowed_packet = 1M

table_open_cache = 256

sort_buffer_size = 1M

read_buffer_size = 1M

read_rnd_buffer_size = 4M

myisam_sort_buffer_size = 64M

thread_cache_size = 8

query_cache_size= 16M

# Try number of CPU's*2 for thread_concurrency

thread_concurrency = 8

default-character-set=utf8

log_bin_trust_function_creators = 1

注意：my.ini配置文件一定要有。

5.???????mysql数据库安装好后，找到其安装目录下data文件夹，将数据库文件拷入data文件夹内。然后启动其安装目录下bin文件夹里面的mysqld。
