改apache配置文件内模块为libphp7.so

vim /etc/httpd/conf/httpd.conf
LoadModule php7_module        /usr/lib64/httpd/modules/libphp7.so

增加一行解析

/etc/httpd/conf.d/php.conf

AddType application/x-httpd-php-source .phps

验证php 版本：

<?php
phpinfo();
?>

遇到问题：

with-apx2 checking for Apache 2.0 handler-module support via DSO through
yum install httpd-devel

php configure: error: Don't know how to define struct flock on this system, set --enable-opcache=no
export LD_LIBRARY_PATH=/lib/:/usr/lib/:/usr/local/lib

如下是编译apache, 如果自己编译的话

wget ftp://mcrypt.hellug.gr/pub/crypto/mcrypt/attic/libmcrypt/libmcrypt-2.5.7.tar.gz 
tar -zxvf libmcrypt-2.5.7.tar.gz 
cd libmcrypt-2.5.7 
./configure
make
make install 
cd ..

wget http://archive.apache.org/dist/apr/apr-1.5.2.tar.gz
 tar -zxf apr-1.5.2.tar.gz
cd apr-1.5.2
 ./configure --prefix=/usr/local/apr 
 make -j18  && make install
 cd ..

 wget http://archive.apache.org/dist/apr/apr-util-1.5.3.tar.gz
 tar -zxf apr-util-1.5.3.tar.gz
cd apr-util-1.5.3
 ./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr
 make -j18 && make install
 cd ..

 wget http://mirrors.noc.im/apache//httpd/httpd-2.4.18.tar.gz
 tar xzf httpd-2.4.18.tar.gz 
cd httpd-2.4.18
./configure --prefix=/usr/local/apache_2.4.18 \
--with-apr=/usr/local/apr \
--with-apr-util=/usr/local/apr-util 
make -j18 && make install

这个编译的话，最好在php 前面，然后--with-apx2=/youPath/bin/apx2
