## 1.4 若出现mysql不是内部或外部命令，需要我们再次手动增加mysql的环境变量。 ##

（1）找到mysql的安装位置，默认在C:\\Program Files\\MySQL\\MySQL Server 5.5  
（2）找到桌面计算机，右键选择属性，点击高级系统设置，选择环境变量。找到系统变量中以PATH开头的一行。![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDc4NDY3Mw_size_16_color_FFFFFF_t_70 22]  
（3）双击PATH这一行，在最后输入  
;C:\\Program Files\\MySQL\\MySQL Server 5.5\\bin  
一直确定即可，再次运行mysql，即可进入。
