php7 Linux安装卸载教程(详解)

一、安装

我第一次安装php的时候没有安装apache的php模块,结果apache不能解析php文件,访问文件显示的是源码。

一个命令搞定:安装php7和apache的php7模块:

apt-get install php7.0 libapache2-mod-php7.0

重启apache:

/etc/init.d/apache2 restart

/var/www/html目录下新建文件info.php

内容如下:

<?php  
    phpinfo()
?>

访问:http://你的主机IP/info.php

看到这个表示php7安装ok。

查看php7相关组件:apt-cache search php7

安装两个重要的组件,特别是php7.0-mysql,使php7获得mysql的支持。

apt-get install php7.0-mysql php7.0-gd

二、卸载(第一种)

sudo apt-get - -purge remove libapache2-mod-php7.0 php7.0 php7.0-gd php7.0-mysql  (安装了哪些组件就跟上名字,我这里只安装了这4个)
sudo apt-get autoremove php7.0

三,卸载(第二种)

sudo aptitude purge `dpkg -l | grep php| awk &#39;{print $2}&#39; |tr "\n" " "`

查询,卸载已安装php,就卸载完了。

(如果aptitude命令报错就安装aptiude:apt-get install aptitude)

如果想要安装其他php版本:

添加支持源

add-apt-repository ppa:ondrej/php

接下来就apt-get安装就好了。

四、php打开session支持

在php.ini里找到session.auto_start = 0(我新安装的php5默认值就是0),把0改为1就可以了。
