mysql解压缩版安装

1，复制一份my-default.ini，重命名为my.ini做完配置文件
2，修改配置文件内容，如安装路径，工作目录，基础编码等，两个相关路径必须修改，其他为设置utf-8mb4为基础编码

设置剩余环境为utf-8mb4
SET character_set_client = utf8mb4;
SET character_set_results = utf8mb4;
SET character_set_database = utf8mb4;
SET character_set_connection = utf8mb4;
SET collation_connection = utf8mb4_general_ci
查询编码环境
SHOW VARIABLES WHERE Variable_name LIKE 'character\_set\_%' OR Variable_name LIKE 'collation%';

[client]
default-character-set=utf8mb4
[mysql]
default-character-set=utf8mb4


[mysqld]
#安装路径
basedir = C:\mysql-5.6.17-winx64
#数据文件路径
datadir = C:\mysql-5.6.17-winx64\data
port = 3306

character-set-client-handshake = FALSE 
character-set-server = utf8mb4 
collation-server = utf8mb4_unicode_ci 
init_connect='SET NAMES utf8mb4


sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES 

3，在mysql安装目录bin下打开命令行，运行mysqld install MySQL --defaults-file=“C:\mysql-5.6.17-winx64\my.ini”
