2、配置MySQL环境变量

意思就是在/usr/local/mysql/bin/里把mysql添加到环境变量

(1)打开终端，输入：sudo vim ~/.bash_profile(执行root权限，当前用户的根目录下的.bash_profile)

(2)然后在里面输入：export PATH=$PATH:/usr/local/mysql/bin

(3)按ESC，然后输入：:wq

(4)source ~/.bash_profile（重新加载）

(5)控制台输入mysql --version，查看版本号就成功了

cd /usr/local/mysql/bin 
sudo su
Password:
