PHP官网www.php.net
当前主流版本为5.6/7.1

一、PHP5安装

 cd /usr/local/src/
 wget http://cn2.php.net/distributions/php-5.6.30.tar.gz
 tar zxf php-5.6.30.tar.gz
 cd php-5.6.30
 ./configure --prefix=/usr/local/php --with-apxs2=/usr/local/apache2.4/bin/apxs --with-config-file-path=/usr/local/php/etc  --with-mysql=/usr/local/mysql --with-pdo-mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config --with-libxml-dir --with-gd --with-jpeg-dir --with-png-dir --with-freetype-dir --with-iconv-dir --with-zlib-dir --with-bz2 --with-openssl --with-mcrypt --enable-soap --enable-gd-native-ttf --enable-mbstring --enable-sockets --enable-exif

php编译配置文件中指定了apache和mysql的路径，所以说需要先安装apache和mysql，初次安装会缺少各种库文件

yum list | grep xml2
yum install -y libxml2-devel.x86_64

configure: error: Cannot find OpenSSL‘s <evp.h>

yum install -y  openssl-devel

基本都是缺少库文件，相同方法就可以解决问题 安装 libxxxx-devel 或者 xxx-devel 即可

• 常缺少的库文件安装

  yum install -y libxml2-devel.x86_64
  yum install -y openssl-devel
  yum install -y bzip2-devel
  yum install -y libpng-devel
  yum install -y freetype-devel
  yum install -y epel-release
  yum install -y libmcrypt-devel

  完成之后（记得echo $? 检查是否成）

  make && make install
  cp php.ini-production  /usr/local/php/etc/php.ini   //复制配置文件

  /usr/local/php/bin/php -i | less     //查看php的配置信息

  

/usr/local/php/bin/php -m //查看php的扩展，都是静态的

二、PHP7安装

cd /usr/local/src/
 wget http://cn2.php.net/distributions/php-7.1.6.tar.bz2
 tar jxvf php-7.1.6.tar.bz2
 cd php-7.1.6
 ./configure --prefix=/usr/local/php7 --with-apxs2=/usr/local/apache2.4/bin/apxs --with-config-file-path=/usr/local/php7/etc  --with-pdo-mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config --with-libxml-dir --with-gd --with-jpeg-dir --with-png-dir --with-freetype-dir --with-iconv-dir --with-zlib-dir --with-bz2 --with-openssl --with-mcrypt --enable-soap --enable-gd-native-ttf --enable-mbstring --enable-sockets --enable-exif
 make && make install
 ls /usr/local/apache2.4/modules/libphp7.so
 cp php.ini-production  /usr/local/php7/etc/php.ini

ls /usr/local/apache2.4/modules/ | grep libphp  //apache需要的就是这两个扩展文件

vim /usr/local/apache2.4/conf/httpd.conf  //查看apache加载了哪些扩展，不需要的直接#注释掉即可

/usr/local/php7/bin/php -i | less  //查看php7的配置相关信息

• Linux下查看Nginx、Napache、MySQL、PHP的编译参数的命令如下：
