1.复制php压缩包到/usr/local/src
2.解压
tar -zxvf php-7.1.2.tar.gz
3.编译安装(请先安装apache和mysql)
./configure --prefix=/usr/local/php7
--with-apxs2=/usr/local/apache2/bin/apxs
--with-curl
--with-freetype-dir
--with-gd
--with-gettext
--with-iconv-dir
--with-kerberos
--with-libdir=lib64
--with-libxml-dir
--with-mysqli
--with-openssl
--with-pcre-regex
--with-pdo-mysql
--with-pdo-sqlite
--with-pear
--with-png-dir
--with-xmlrpc
--with-xsl
--with-zlib
--enable-fpm
--enable-bcmath
--enable-libxml
--enable-inline-optimization
--enable-gd-native-ttf
--enable-mbregex
--enable-mbstring
--enable-opcache
--enable-pcntl
--enable-shmop
--enable-soap
--enable-sockets
--enable-sysvsem
--enable-xml
--enable-zip
--enable-maintainer-zts
核心就是配置关联
--with-apxs2=/usr/local/apache2/bin/apxs
4.如果有编译错误
yum安装
yum -y install libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel pcre-devel openssl openssl-devel curl-devel libxslt-devel
5.make && make install
make && make install
如果有残留make clean一下
make clean
make
make install
[root@localhost php-7.1.2]# make install

6.apache与php的关联
PHP安装成功后会在apache的modules目录下生成一个libphp.so动态库文件，在apache的配置文件httpd.conf里自动增加一行。
vi /etc/httpd/httpd.conf
LoadModule php7_module modules/libphp7.so
在Apache的配置文件httpd.conf的<IfModule mime_module></IfModule>块里增加一行
AddType application/x-httpd-php .php
配置index.php为默认执行的文件
<IfModule dir_module>
DirectoryIndex index.html index.php
</IfModule>
7.重启apache
可能会出现 Could not reliably determine the server's fully qualified domain name
解决方案：
用记事本打开 httpd.conf
将里面的 #ServerName localhost:80 注释去掉即可。
再执行 httpd
然后可以通过浏览器访问 http://localhost:80 ，如果页面显示 “It works！” ，即表示apache已安装并启动成功。
8.查看phpinfo()
这些都是php支持mysql的模块，不需要跟具体的mysql关联。
9.写代码查看sql连接
$conn=mysqli_connect("127.0.0.1","root","123456");
if($conn){
echo"ok";
}else{
echo"error";
}
附上yum一些指令，避免yum的mysql的干扰！
查询yum的安装包
yum list installed
查看具体的包信息
yum info mysql
移除mysql
yum remove mysql-libs.x86_64
不会影响到自己编译的mysql
