linux php命令安装

1.添加php命令，在etc/profile文件下增加

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）


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

php的路径查看phpinfo中的 Configuration File (php.ini) Path

// 添加好路径后，执行以下代码
sourec /etc/profile

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

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

2.使用 命令

# php -m 
# php -i
