推荐:《PHP视频教程》
Linux 下安装配置 PHP
1)下载PHP安装包,下载地址: http://www.php.net/downloads.php ,这里选用PHP 5.6版本
并解压PHP安装包
wget cn2.php.net/get/php-5.6.31.tar.gz/from/this/mirror gzip -d php-5.6.31.tar.gz tar xvf php-5.6.31.tar
2)添加www用户组和www用户(如果系统中已存在该用户组,不用添加该用户组)
groupadd www useradd -g www -s /sbin/nologin -M www
3) 使用su超级用户登录Linux ,编译PHP参数
su #./configure \\\\ --prefix=/usr/local/php \\\\ --with-mysql=/usr/local/mysql \\\\ --with-apxs=/usr/local/apache2/bin/apxs \\\\
--prefix 指定安装路径
--with-mysql 指定mysql路径
--with-apxs 指定apahce路径
在接下来的编译过程如果报错,可以根据报错调用 ./configure --help查看编译参数,并下载安装相应的依赖包;
4)编译,安装PHP
make make install
5)修改Apache的配置文件,使其支持php, 对 apache 的 httpd.conf 作以下修改
在“ AddType application/x-gzip .gz .tgz”下添加
AddType application/x-httpd-php .php AddType application/x-httpd-php-source .php5
在""内的内容添加"index.php",即如下:
<IfModule dir_module> DirectoryIndex index.html index.php </IfModule>
将" #ServerName www.example.com:80" 修改为
ServerName 127.0.0.1:80
或
ServerName localhost:80
6)复制 php-5.6.31安装包中的配置文件
cp php-5.6.31/php.ini.dist /usr/local/php/lib/php.ini
如果“ php.ini.dist”不存在,可以将“ php.ini-development ”或“ php.ini-production”之一更改为“ php.ini.dist”再执行以上指令
更改 php.ini 文件
register_globals = On
7)测试安装是否完成
重启Apache
service apache restart
随便编写一个php 文件(加入命名为test.php),放置在apache/htdoc中,在浏览器其中访问: http://127.0.0.1/test.php
如果能够正确显示php文件中的内容,则安装成功;
快速安装方式
在Centos下可以使用yum工具,在Ubuntu下使用apt-get工具,可以实现快速的安装方式,用法基本一样,这里演示使用yum安装PHP
1)查看系统中是否已经存在PHP
rpm -qa php
2) 安装PHP
yum -y install php
3)查看PHP安装信息
chkconfig php on
如果yum源上的php版本过低,比如要安装php5.6版本,可以通过以下方法:
1)配置centos epel 和 remi源
# Centos 6 rpm -Uvh http://ftp.iij.ad.jp/pub/linux/fedora/epel/6/x86_64/epel-release-6-8.noarch.rpm rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm #Centos 7 yum install epel-release
rpm -ivh http://rpms.famillecollet.com/enterprise/remi-release-7.rpm
2)查看可安装包
yum list --enablerepo=remi --enablerepo=remi-php56 | grep php
3)安装PHP
yum install --enablerepo=remi --enablerepo=remi-php56 php php-opcache php-devel php-mbstring php-mcrypt php-mysqlnd php-phpunit-PHPUnit php-pecl-xdebug php-pecl-xhprof
