实现LAMP
1.LAMP工作原理
LAMP是一个强大的Web应用程序平台，其中L是指linux系统；A是指apache也就是http;M一般是mysql/mariadb数据库;P一般是php, perl, python其中之一。
工作过程：
1》当客户端请求的是静态资源时，web服务器会直接把静态资源返回客户端；
2》当客户端请求的是动态资源时，httpd的php模块会进行相应的动态资源运算，如果此过程还需要数据库的数据作为运算参数时，php会连接mysql取得数据然后进行运算，运算的结果转为静态资源并由web服务器返回到客户端。
2.使用yum安装实现LAMP
1）实现环境条件
1》需要两天主机，一台实现LAP,另一台实现M.
2》在两台主机上使用iptables -F关闭防火墙，使用setenforce 0来暂时设置selinux为permisive，或者配置/etc/selinux/config来设置selinux为disable或permisive。
2）所需安装的程序包
centos6需要：httpd、php、php-mysql、mysql、mysql-server、mysql-libs
centos7需要：httpd、php-fpm(or php)、php-mysql、mariadb、mariadb-server、mariadb-libs
3）centos6和7上实现
1>安装httpd并开启
centos6上配置为：
yum install httpd
chkconfig httpd on
chkconfig --list httpd
service httpd start
service httpd status
centos7上配置为：
yum install httpd
systemctl enable httpd
systemctl start httpd
systemctl status httpd
2>安装mysql并开启
centos6上配置为：
yum install mysql mysql-server mysql-libs
chkconfig mysqld on
chkconfig --list mysqld
service mysqld start
service mysqld status
/usr/bin/mysql_secure_installation
mysql -uroot -pxm1234
mysql>create user "shenxm"@'%' identified by 'xm1234';
centos7上配置为：
yum install mariadb mariadb-libs mariadb-server
systemctl enable mariadb
systemctl start mariadb
systemctl status mariadb
/usr/bin/mysql_secure_installation
mysql -uroot -pxm1234
MariaDB [(none)]>create user "shenxm"@'%' identified by 'xm1234';
3>安装php相关包
centos6上配置为：
yum install php php-mysql
vim /etc/httpd/conf/httpd.conf
在文件尾部加两行
AddType application/x-httpd-php .php
AddType application/x-httpd-php-source .phps
修改或添加下面内容
<IfModule dir_module>
DirectoryIndex index.php index.html
</IfModule>
service httpd restart
centos7上配置为：
下面模式二选一
1）modules：
yum install php php-mysql
vim /etc/httpd/conf/httpd.conf
在文件尾部加两行
AddType application/x-httpd-php .php
AddType application/x-httpd-php-source .phps
添加修改下面行
<IfModule dir_module>
DirectoryIndex index.php index.html
</IfModule>
systemctl restart httpd
2）fastcgi：
yum install php-fpm php-mysql
vim /etc/httpd/conf/httpd.conf
在文件尾部加四行
AddType application/x-httpd-php .php
AddType application/x-httpd-php-source .phps
ProxyRequests Off
ProxyPassMatch ^/(.*.php)$ fcgi://127.0.0.1:9000/app/httpd24/htdocs/$1
修改下面行
<IfModule dir_module>
DirectoryIndex index.php index.html
</IfModule>
systemctl restart httpd
systemctl start php-fpm
4>测试配置的LAMP是否成功
vim /var/www/html/index.php
<html><body><h1>It works!</h1></body></html>
<?php
echo date("Y/m/d h:i:s");
$mysqli=new mysqli("192.168.213.252","wpuser","xm1234");
if(mysqli_connect_errno()){
echo "连接数据库失败!";
$mysqli=null;
exit;
}
echo "连接数据库成功!";
$mysqli->close();
phpinfo();
?>
3.脚本实现源码编译安装LAMP
这是将编译安装实现LAMP的操作写成脚本，通过脚本来实现快速实现。
1）实现环境条件
1》因为这是一个脚本，所以用一台主机来直接实现LAMPM。当然，也可以把脚本分成几个模块，就如同分为centos6和7一样，可以把每个功能分别独立设立为模块，然后需要那个就调用那个应用来配合完成，这样修改或排错的时候更清晰。
2》在主机上使用iptables -F关闭防火墙，使用setenforce 0来暂时设置selinux为permisive，或者配置/etc/selinux/config来设置selinux为disable或permisive。
2）所需的软件包
软件包的版本可以根据需要来进行选择。且需要先创建个/app的目录，把所有软件包都放到这个目录下。
centos7：
apr-1.6.2.tar.gz
httpd-2.4.27.tar.bz2
php-7.1.10.tar.xz
apr-util-1.6.0.tar.gz
mariadb-10.2.8-linux-x86_64.tar.gz
centos6：
apr-1.6.2.tar.gz
httpd-2.4.27.tar.bz2
php-5.6.31.tar.xz
xcache-3.2.0.tar.bz2
apr-util-1.6.0.tar.gz
mariadb-5.5.57-linux-x86_64.tar.gz
3）编写脚本
