CentOS7单机部署lamp环境和apache虚拟主机

（1）apache介绍

apache : httpd.apache.org 
软件包：httpd 
端口服务：80/tcp(http) 443/tcp(https,http+ssl)
配置文件： 
    /etc/httpd/conf/httpd.conf 
    /etc/httpd/conf.d/*.conf 
    /etc/httpd/conf.d/welcome.conf          //默认测试页面

（2）lamp环境安装

1.关闭防火墙和selinux

systemctl stop firewalld.service 
systemctl disable firewalld.service
sed -ri '/^SELINUX=/cSELINUX=disabled' /etc/sysconfig/selinux
setenforce 0

2.安装和启动apache

yum install httpd -y 
systemctl start httpd 
systemctl enable httpd 

3.安装php

yum install php -y          //php作为apache的模块
yum install php-mysql -y    //安装php连接mysql扩展模块
yum install gd php-gd -y 
php -m                      //查看php有哪些扩展模块
ll /etc/httpd/modules/libphp5.so 
ll /etc/httpd/conf.d/php.conf 
systemctl restart httpd

4.安装mariadb

yum install mariadb-server mariadb  -y 
systemctl start mariadb
systemctl enable mariadb 
mysql_secure_installation       //修改root默认密码
mysql -uroot -p                 //登录mariadb测试

5.测试apache和php

cd /var/www/html 
#vim index.php
<?php
phpinfo();
?>

http://192.168.1.2

6.测试php和mariadb

cd /var/www/html 
#vim index.php
<?php
$link=mysql_connect('localhost','root','mysql密码')
if($link)
    echo "successfuly";
else 
    echo "Faile";
mysql_close();
?>

http://192.168.1.2

7.apache目录介绍

# ll /etc/httpd/
conf                                        //配置文件目录
conf.d                                      //配置文件目录
conf.modules.d                              //模块目录
logs -> ../../var/log/httpd                 //日志目录
modules -> ../../usr/lib64/httpd/modules    //模块目录
run -> /run/httpd                           //httpd进程pid在这个文件

8.apache配置文件详解

ServerRoot "/etc/httpd"                     //安装目录
Listen 80                                   //监听端口
User apache                                 //运行apache的用户
Group apache                                //运行apache的用户组
DocumentRoot "/var/www/html"                //站点默认主目录
IncludeOptional conf.d/*.conf               //包含conf.d/*.conf的文件
<Directory "/var/www">                      //设定访问控制权限，如果修改了站点主目录，这里也需要修改
    AllowOverride None
    # Allow open access:
    Require all granted                     //允许所有主机访问
</Directory>

（3）虚拟主机：基于主机地址

1.配置主机地址www.test.com的虚拟主机

#vim /etc/httpd/conf.d/blog.conf
<VirtualHost *:80>
    DocumentRoot "/var/www/blog"
    ServerName blog.test.com
    ErrorLog "/var/log/blog-error_log"
    CustomLog "/var/log/blog-access_log" common
</VirtualHost>
<Directory "/var/www/blog">
    AllowOverride None
    Require all granted
</Directory>

2.创建目录,修改属主,准备主页

mkdir /var/www/blog
chown -R apache.apache /var/www/blog
echo "blog.test.com" >>/var/www/blog/index.html

3.检查配置文件和重启服务

httpd -t 
systemctl restart httpd 

4.修改windows的hosts文件

编辑：C:\Windows\System32\drivers\etc\hosts添加一下记录
192.168.111.151 blog.test.com

5.使用浏览器测试访问
