安装php5.6依赖的扩展：
1 yum install -y libxml2-devel openssl-devel libcurl-devel libjpeg-devel libpng-devel libicu-devel openldap-devel
下载解压PHP：
在http://php.net/downloads.php可以下载到最新版本的php，这里下载的是php-5.6.8.tar.gz。
1 wget http://cn2.php.net/distributions/php-5.6.8.tar.gz 2 tar -xzvf php-5.6.8.tar.gz 3 cd php-5.6.8
编译PHP：
./configure --prefix=/usr/local/php \ --with-config-file-path=/usr/local/php/etc \ --enable-inline-optimization \ --disable-debug \ --disable-rpath \ --enable-shared \ --enable-opcache --enable-fpm \ --with-fpm-user=www \ --with-fpm-group=www \ --with-mysql=mysqlnd \ --with-mysqli=mysqlnd \ --with-pdo-mysql=mysqlnd \ --with-gettext \ --enable-mbstring \ --with-iconv \ --with-mcrypt \ --with-mhash \ --with-openssl \ --enable-bcmath \ --enable-soap \ --with-libxml-dir \ --enable-pcntl \ --enable-shmop \ --enable-sysvmsg \ --enable-sysvsem \ --enable-sysvshm \ --enable-sockets \ --with-curl \ --with-zlib \ --enable-zip \ --with-bz2 \ --with-readline \ --with-apxs2=/usr/bin/apxs
configure成功后， 会出现以下内容：

接着执行make， 经过一段时间的等待， 会看到以下内容：
Build complete.
Don't forget to run 'make test'.
虽然它提示要执行make test， 不过我本人测试过， 会出现以下类似问题：

目前还没解决， 如果有已经解决的高手， 帮忙告知下， 谢谢！
此问题对使用php影响不大，所以暂时忽略以上问题。
接着继续执行：
make install
成功的话可以看到以下结果：

然后php -v， 可以看到：

让Apache支持PHP：
打开/etc/httpd/conf/httpd.conf文件，在最后面输入以下代码：
1 AddType application/x-httpd-php .php 2 AddType application/x-httpd-php-source .phps
定位到DirectoryIndex index.html ，修改为：
1 DirectoryIndex index.php index.html
必须要注意的是/etc/httpd/conf/httpd.conf中是否已经开启了php扩展：
1 LoadModule php5_module modules/libphp5.so
第三部分：安装Wordpress（解压后readme.html有安装步骤）
1、下载Wordpress：https://wordpress.org/download/ 点击Download .tar.gz 下载wordpress 压缩包
2、解压wordepress 到目录/opt/lampp/htdocs/下：tar -xzvf wordpress-5.4.tar.gz -C /var/www/html/
3、浏览器中输入http://192.168.1.108/wordpress/index.php ip 为centos7 的ip，由于是首次打开，自动跳转到安装页面http://192.168.1.108/wordpress/wp-admin/setup-config.php
