执行命令：vi /etc/profile
在profile文件中输入如下命令
mysql对应环境变量设置：export PATH=/usr/local/mysql/bin:$PATH
php对应环境变量设置 ：export PATH=$PATH:/usr/local/php/bin
实际操作中根据自己的安装目录修改/usr/local/mysql/bin和/usr/local/php/bin
二、修改之后的内容如下：
# /etc/profile
# System wide environment and startup programs, for login setup
# Functions and aliases go in /etc/bashrc
# It's NOT a good idea to change this file unless you know what you
# are doing. It's much better to create a custom.sh shell script in
# /etc/profile.d/ to make custom changes to your environment, as this
# will prevent the need for merging in future updates.
export PATH=/usr/local/mysql/bin:$PATH
export PATH=$PATH:/usr/local/php/bin
pathmunge () {
case ":${PATH}:" in
*:"$1":*)
;;
*)
if [ "$2" = "after" ] ; then
PATH=$PATH:$1
else
PATH=$1:$PATH
fi
esac
}
三、执行source /etc/profile 让修改过的profile文件立即生效
