## 二、安装需求及下载地址 ##

需求
                Python 2.6
                MySQL Connector/Python 连接器
        下载地址：
                http://dev.mysql.com/downloads/utilities/

## 三、安装示例 ##

###本次安装使用1.6.4版本，安装前，需要先安装mysql到python连接器
    # cat /etc/redhat-release 
    CentOS release 6.7 (Final)
    # rpm -Uvh mysql-connector-python-2.1.4-1.el6.x86_64.rpm 
    # rpm -Uvh mysql-utilities-1.6.4-1.el6.noarch.rpm 
    
    ###如果没有安装连接器，则收到如下错误提示
    # rpm -Uvh mysql-utilities-1.6.4-1.el6.noarch.rpm 
    warning: mysql-utilities-1.6.4-1.el6.noarch.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY
    error: Failed dependencies:
            mysql-connector-python >= 2.0.0 is needed by mysql-utilities-1.6.4-1.el6.noarch
    
    ###查看安装后生成的文件
