安装PHP5
当前主流版本为5.6和7.1

cd /usr/local/src/wget http://cn2.php.net/distributions/php-5.6.30.tar.gztar zxf php-5.6.30.tar.gzcd php-5.6.30[root@wwlinux701 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

/apxs–apache工具，自动能用http-m加载模块

–检测报错解决
checking for xml2-config path…
configure: error: xml2-config not found. Please check your libxml2 installation.

yum install -y libxml2-devel

yum install -y openssl-devel

yum install -y bzip2-devel

yum install -y libjpeg-devel

yum install -y libpng-devel

yum install -y freetype-devel

yum install -y epel-release –需要先安装epel扩展源。借助第三方源安装
yum install -y libmcrypt-devel

./configure到这个提示完成

再make && make install

[root@wwlinux701 php-5.6.30]#cp php.ini-production  /usr/local/php/etc/php.ini#查看是否加载配置文件[root@wwlinux701 php-5.6.30]# /usr/local/php/bin/php -i |less

安装php7

cd /usr/local/srcwget http://php.net/distributions/php-7.1.10.tar.gz -O php-7.1.10.tar.gztar zxf php-7.1.10.tar.gz[root@wwlinux701 php-7.1.10]# ./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
安装完以后下面有两个so文件

[root@wwlinux701 php-7.1.10]# ls /usr/local/apache2.4/modules/libphp
libphp5.so libphp7.so

查看apache加载了几个php
/usr/local/apache2.4/bin/apachectl -M

更改配置文件启用哪个php，不想用哪个就把哪个注释掉
vim /usr/local/apache2.4/conf/httpd.conf

[root@wwlinux701 php-7.1.10]#  ls /usr/local/apache2.4/modules/libphp7.so/usr/local/apache2.4/modules/libphp7.so[root@wwlinux701 php-7.1.10]#  cp php.ini-production  /usr/local/php7/etc/php.ini[root@wwlinux701 php-7.1.10]#
