Mysql安装配置
1. 下载mysql5.5.18绿色版，mysql下载官网：mysql.com。
2. 解压到目录D:mysql5.5.18。
3. 将mysql添加到环境变量path：
;D: mysql5.5.18bin
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。
