Linux下將PHP新增到環境變數，將Mysql加入環境變數。

1.修改/etc/profile

vi /etc/profile

2.新增兩行

PATH=$PATH:/usr/local/php7/bin:/usr/local/mysql/bin
export PATH

usr/local/php7

是php7的安裝路徑

usr/local/mysql

是mysql的安裝路徑

3.執行命令
source /etc/profile

4.檢視是否成功

echo $PATH

[root@localhost ext]# echo $PATH
/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin:/usr/local/php7/bin:/usr/local/mysql/bin

成功了！

[root@localhost ext]# php -version
