Centos7下编译安装PHP

# yum groupinstall "Development Tools"
# yum -y install libxml2 libxml2-devel bzip2-devel curl curl-devel libjpeg-devel libpng libpng-devel libXpm-devel gcc gcc-c++ freetype-devel glib2-devel cairo-devel postgresql-devel libxslt libxslt-devel mysql-devel

【 如果之前的yum groupinstall及yum install相关的准备工作已经完成，下面部分将不会有，如果没有做准备工作，可根据错误提示一次次排错

# yum -y install mysql-devel
】
# make
# make install
# cp php.ini-production /usr/local/php/php5.6/etc/php.ini
配置httpd支持PHP
# vim /etc/httpd/httpd.conf
搜索ServerName,把#ServerName www.example.com:80前面的#号删除(此处未做,在安装Apache时在此处添加ServerName localhost:80)
将<Directory />段中的Require all denied改为Require all granted
在AddType application/x-gzip .gz .tgz下面添加一行AddType application/x-httpd-php .php
在<IfModule dir _module>段中添加
    AddType application/x-httpd-php .php
在启动httpd之前检验配置文件是否正确
# /usr/local/apache24/bin/apachectl –t
启动apache
# /usr/local/apache24/bin/apachectl start
测试
# curl localhost
测试是否正确解析PHP
# vim /usr/local/apache24/htdocs/1.php
输入PHP代码，然后在浏览器中输入IP/1.php测试
====================================================
默认虚拟主机
# vim /etc/httpd/httpd.conf
# Virtual hosts
Include /etc/httpd/extra/httpd-vhosts.conf ==去掉行首的#
# vim /etc/httpd/extra/httpd-vhosts.conf
默认内容
<VirtualHost *:80>  #默认虚拟主机
ServerAdmin [e-mail]
DocumentRoot "/usr/local/apache24/docs/dummy-host.example.com"
ServerName dummy-host.example.com  #网站域名,只能有一个
ServerAlias www.dummy-host.example.com　#网站第二域名,可以有多个,中间用空格隔开
ErrorLog "logs/dummy-host.example.com-error_log" #错误日志
CustomLog "logs/dummy-host.example.com-access_log" common #访问日志
</VirtualHost>

<VirtualHost *:80>
ServerAdmin [e-mail]
DocumentRoot "/usr/local/apache24/docs/dummy-host2.example.com"
ServerName dummy-host2.example.com
ErrorLog "logs/dummy-host2.example.com-error_log"
CustomLog "logs/dummy-host2.example.com-access_log" common
</VirtualHost>
修改后
<VirtualHost *:80> 
ServerAdmin [e-mail]
DocumentRoot "/data/wwwroot/aming.com"
ServerName aming.com 
ServerAlias www.aming.com　
ErrorLog "logs/aming.com-error_log"
CustomLog "logs/aming.com-access_log" common
</VirtualHost>

<VirtualHost *:80>
DocumentRoot "/data/wwwroot/www.123.com"
ServerName www.123.com
</VirtualHost>
测试:
# mkdir -p /data/wwwroot/aming.com /data/wwwroot/www.123.com
# echo "aming.com" > /data/wwwroot/aming.com/index.html
# echo "123.com" > /data/wwwroot/www.123.com/index.html
# /usr/local/apache24/bin/apachectl -t
# /usr/local/apache24/bin/apachectl graceful //这个操作是重新加载httpd服务
# curl -x127.0.0.1:80 aming.com
# curl -x127.0.0.1:80 www.abc.com
如果显示You don't have permission to access /index.html on this server. 则表示权限设置有误，修改httpd.conf将"Deny from all"这行给注释掉就可以了。
