3. Compile and install

[[email protected] php-5.6.30]# make           //编译[[email protected] php-5.6.30]# echo $?       //检查上一条命令是否正确[[email protected] php-5.6.30]# make install             //安装[[email protected] php-5.6.30]# echo $?                   //检查上一条命令是否正确，也就是安装是否出错

4. Configuration files

[[email protected] php-5.6.30]# cp php.ini-php.ini-development  php.ini-production   [[email protected] php-5.6.30]# cp php.ini-production /usr/local/php/etc/php.ini       //正常情况下使用php.ini-production，开发环境可以使用php.ini-development[[email protected] php-5.6.30]# /usr/local/php/bin/php -i | less

5. Check if Apache is properly called

[[email protected] php-5.6.30]# cat /usr/local/apache2/conf/httpd.conf | grep phpLoadModule php5_module        modules/libphp5.so

Second, PHP7 installation

The installation process is similar to the PHP5 installation process.
It is important to note that:

Apache servers can have 2 versions of PHP, and close a version of the PHP module by commenting out the corresponding lines in the Apache configuration file.

 [[email protected] ~]# vim /usr/local/apache2/conf/httpd.conf

If you do not use PHP7, add it in LoadMoudle front # .
