直接运行mysql和php命令提示未找到命令的报错，如：-bash: mysql: command not found ---解决办法-- CentOS下给mysql、php配置环境变量

一、运行mysql -uroot -p命令报错：

[root@localhost ~]# mysql -uroot -p
-bash: mysql: command not found

解决，给mysql配置环境变量：

[root@localhost ~]# vim /etc/profile
export PATH=$PATH:/usr/local/mysql/bin

[root@localhost ~]# source /etc/profile

[root@localhost ~]# mysql -uroot -p
Enter password:

tips：
报错是因为没有找到路径，敲完完整路径就不会报错，就是路径有点长，敲起来麻烦，所以添加环境变量，方便：
完整路径：/usr/local/mysql/bin/mysql -uroot -p
完整路径：/usr/local/php/bin/php -v
