好像直接把PHP+APACHE+MYSQL服务启动就可以,因为LINUX已经安装了这些,只需要启动它,下次配置时验证
一、安装Apache2
#yum -y install httpd
安装完成之后查看安装时生成了哪些文件:
#
rpm -ql httpd
启动httpd服务
#service httpd start
二、安装Mysql
1.安装mysql
#yum -y install mysql-server
安装完成,启动mysql服务:
#service mysqld start

出现错误:
Yum编译安装Error Downloading Packages报错
解决办法:
解决思路:
1:执行yum clean all 清除缓存目录下的软件包及旧的headers;
2:接着执行 yum list 重新列出所有已经安装和可以安装的软件包;
3:重新执行上述命令,发现yum编译成功;

登录
mysql -u root -p123456
三、安装PHP
#yum -y install php
安装完成php之后,重启httpd服务,在网站根目录下面写一个php文件测试。
#vim /var/www/html/index.php
我们使用输出php配置信息来测试,在index.php输入以下内容:
<?php
phpinfo();
?>
如果能正确输出php配置信息表示安装成功,继续下一步。
