linux下如何安装php命令

具体方法：

（推荐教程：php教程）

1、在etc/profile文件下增加配置export PATH=$PATH:/usr/local/php/lib

文件内容如下：

if [ "$HISTCONTROL" = "ignorespace" ] ; then
 export HISTCONTROL=ignoreboth
else
 export HISTCONTROL=ignoredups
fi

export PATH USER LOGNAME MAIL HOSTNAME HISTSIZE HISTCONTROL
export PATH=$PATH:/usr/local/php/lib // 增加此段代码（php的路径）
#export PATH =/usr/local/php/bin/php

# By default, we want umask to get set. This sets it for login shell
# Current threshold for system reserved uid/gids is 200

2、添加好路径后，执行以下代码

source /etc/profile

source /etc/profile //centos 7

如果报错：

[root@localhost html]# php -m
-bash: php: command not found

解决办法：

# which php //结果是/usr/local/php/bin/php
# ln -s /usr/local/php/bin/php /usr/bin/php

3、测试

# php -m 
# php -i
