PHP安装

PHP的安装需要apache和mysql两个基础环境
     第一步:查看是否安装apache和mysql
     1、rpm -qa |grep mysql
        rpm -qa |grep httpd
     2、netstat -atunp |grep mysql
        netstat -atunp |grep httpd
  3、ps -ef |grep mysql
        ps -ef lgrep httpd
  4、1sof -i :3306
        lsof -i :80
     
  查看是否有apxs:
     rpm -ql httpd-devel |grep apxs
  find / -name "apxs”
     如果没有apxs,安装httpd-devel: yum install httpd-devel
  
     第二步:上传到服务器后,解压到指定目录
     tar -zxvf php-8.1.4.tar.gz -C /usr/local/
    
  第三步:安装依赖包:
     yum install zlib libxml libjpeg freetype libpng gd curl libiconv zlib-devel
  libxml2 libxml2-devel libjpeg-devel freetype-devel libpng-devel gd-devel 
  curl-devel openssl-devel 1ibxslt-devel -y

配置apache支持PHP程序
修改apache的配置文件：
修改前备份：cp httpd.conf httpd.conf.bak
修改内容：
1、
User php
Group php

2、# If your host doesn't have a registered DNS name, enter its IP address here.
ServerName localhost:80

3、<IfModule dir_module>
    DirectoryIndex index.php index.html 404.html
</IfModule>

4、 # If the AddEncoding directives above are commented-out, then you
    # probably should define those extensions to indicate media types:
    #
    AddType application/x-compress .Z
    AddType application/x-gzip .gz .tgz
    AddType application/x-httpd-php .php .phtml
    AddType application/x-httpd-php-source .phps

启动httpd，mysqld

systemctl start httpd   #启动并加入开机自启动httpd

systemctl enable httpd

systemctl start mariadb  #启动并加入开机自启动mysqld

systemctl enable mariadb
 

 配置测试首页文件
在apache的发布目录：/var/www/html 中
vim index.php
写入： <?php
         phpinfo();
       ?>
保存后退出，在浏览器输入服务器IP测试。
