1、安装所需要的lib库
yum -y install zlib-devel libxml2-devel libjpeg-turbo-devel libiconv-devel （安装）
rpm -qa zlib-devel libxml2-devel libjpeg-turbo-devel libiconv-devel （检查）
yum -y install freetype-devel libpng-devel gd-devel libcurl-devel libxslt-devel
libiconv库不能安装
cd /usr/local （进去安装目录）
wget http://ftp.org/pub/gnu/libiconv/libiconv-1.14.tar.gz
tar -zxvf libiconv-1.14.tar.gz
cd libiconv-1.14
./configure --prefix=/usr/local
make
make install
2、安装libmcrypt
默认的yum里没有libmcrypt库。利用第三方yum安装，事先配置好epel
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-6.repo (配置epel）
yum -y install libmcrypt-devel
yum -y install mhash
yum -y install mcrypt
yum -y install freetype-devel curl-devel
yum install libxslt-devel* -y
二、开始安装php
1、下载网站 http://cn.php.net
wget http://cn2.php.net/get/php-php-7.2.15.tar.gz
2、配置和环境检查
./configure \
--prefix=/usr/local/php \
--with-mysql=/usr/local/mysql \
--with-iconv-dir=/usr/local/libiconv \
--with-freetype-dir \
--with-jpeg-dir \
--with-png-dir \
--with-zlib \
--with-libxml-dir=/usr \
--enable-xml \
--disable-rpath \
--enable-safe-mode \
--enable-bcmath \
--enable-shmop \
--enable-sysvsem \
--enable-inline-optimization \
--with-curl \
--with-curlwrappers \
--enable-mbregex \
--enable-fpm \
--enable-mbstring \
--with-mcrypt \
--with-gd \
--enable-gd-native-ttf \
--with-openssl \
--with-mhash \
--enable-pcntl \
--enable-sockets \
--with-xmlrpc \
--enable-zip \
--enable-soap \
--enable-short-tags \
--enable-zend-multibyte \
--enable-static \
--with-xsl \
--with-fpm-user=nginx \
--with-fgm-group=nginx \
--enable-ftp
2、配置和环境检查高版本
./configure \
--prefix=/usr/local/php \
--with-mysql=/usr/local/mysql \
--with-pdo-mysqlnd \
--with-iconv-dir=/usr/local/libiconv \
--with-freetype-dir \
--with-jpeg-dir \
--with-png-dir \
--with-zlib \
--with-libxml-dir=/usr \
--enable-xml \
--disable-rpath \
--enable-bcmath \
--enable-shmop \
--enable-sysvsem \
--enable-inline-optimization \
--with-curl \
--enable-mbregex \
--enable-fpm \
--enable-mbstring \
--with-mcrypt \
--with-gd \
--enable-gd-native-ttf \
--with-openssl \
--with-mhash \
--enable-pcntl \
--enable-sockets \
--with-xmlrpc \
--enable-soap \
--enable-short-tags \
--enable-static \
--with-xsl \
--with-fpm-user=nginx \
--with-fgm-group=nginx \

Thank you for using PHP.
make
成功如下提示：
Build complete
Don’t forget to ‘make test’
make install
成功如下提示：
/usr/local/php-7.2.15/build/shtool install -c ext/phar/phar.phar /usr/local/php/bin
ln -s -f phar.phar /usr/local/php/bin/phar
Installing PDO headers: /usr/local/php/include/php/ext/pdo/
3、cp php.ini-production /usr/local/php/lib/php.ini （php的引擎文件拷贝到默认目录并且改名）
4、cd /usr/local/php/etc
cp php-fpm.conf.default php-fpm.conf
5、配置www.conf，配置用户的文件：cp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/www.conf
(低版本没有）
三。配置nginx支持php
1、修改：server模块中的location
location ~ .*\.(php|php5)?$ {
root html/blog;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fastcgi.conf;
}
vi /etc/sysconfig/iptables 添加防火墙端口
-A INPUT -m state --state NEW -m tcp -p tcp --dport 9000 -j ACCEPT
/usr/local/php/sbin/php-fpm （启动php-fpm）
