macbook设置环境变量
在macbook上安装了phpstudy,然后执行php -v和mysql -v都报错
于是进入phpstudy的安装目录,然后再执行,这样很麻烦,于是做了软链,还是有点麻烦,每次都要./php和./mysql
于是开始设置环境变量,将php和mysql加入环境变量,这样在任何目录都可以直接使用php和mysql命令
如此操作
bash-3.2# pwd
/private/var/root
bash-3.2# cat
bash-3.2#
bash-3.2# echo $SHELL
/bin/bash
bash-3.2# cat /etc/bashrc
# System-wide .bashrc file for interactive bash(1) shells.
if [ -z "$PS1" ]; then
return
fi
PS1='\h:\W \u\$ '
# Make bash check its window size after a process completes
shopt -s checkwinsize
[ -r "/etc/bashrc_$TERM_PROGRAM" ] && . "/etc/bashrc_$TERM_PROGRAM"
export PATH="$PATH:/Applications/phpstudy/Extensions/php/php7.3.11/bin:/Applications/phpstudy/Extensions/MySQL5.7.28/bin"
bash-3.2# source /etc/bashrc
然后就可以在任何目录中使用php和mysql了,不用频繁切换目录,很方便。
