1. 首先释放安装包：
tar -xvzf php-7.3.2.tar.gz.gz cd php-7.3.2
2. 接下来进行参数配置，配置前如果没有libxml2和libxml2-devel会报错，所以应该更新libxml2并安装libxml2-devel，使用在线安装：
yum -y install libxml2 yum -y install libxml2-devel
yum -y install openssl
yum -y install openssl-devel
yum -y install curl
yum -y install curl-devel
yum -y install libjpeg
yum -y install libjpeg-devel
yum -y install libpng
yum -y install libpng-devel
yum -y install freetype
yum -y install freetype-devel
yum -y install pcre
yum -y install pcre-devel
yum -y install libxslt
yum -y install libxslt-devel
yum -y install bzip2
yum -y install bzip2-devel
./configure --prefix=/usr/local/php --with-curl --with-freetype-dir --with-gd --with-gettext --with-iconv-dir --with-kerberos --with-libdir=lib64 --with-libxml-dir --with-mysqli --with-openssl --with-pcre-regex --with-pdo-mysql --with-pdo-sqlite --with-pear --with-png-dir --with-jpeg-dir --with-xmlrpc --with-xsl --with-zlib --with-bz2 --with-mhash --enable-fpm --enable-bcmath --enable-libxml --enable-inline-optimization --enable-mbregex --enable-mbstring --enable-opcache --enable-pcntl --enable-shmop --enable-soap --enable-sockets --enable-sysvsem --enable-sysvshm --enable-xml --enable-zip
可能会报错，提示需要安装zlib
查看yum是否安装，安装了还是提示错误的话就卸载了自己下载源码包编译安装，
如果zlib版本大于1.2的话可能会提示cmake版本过低，要求升级cmake
下载Cmake
wget https://cmake.org/files/v3.6/cmake-3.6.2.tar.gz解压Cmake
将cmake移动到/usr/local/cmake3
make && make install
cp php.ini-development /usr/local/php/lib/php.ini cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf cp sapi/fpm/php-fpm /usr/local/bin
vim /usr/local/php/lib/php.ini
打开php配置文件找到cgi.fix_pathinfo配置项，这一项默认被注释并且值为1
groupadd www-data useradd -g www-data www-data
cp /usr/local/etc/php-fpm.d/www.conf.default /usr/local/etc/php-fpm.d/www.conf vim /usr/local/etc/php-fpm.d/www.conf
默认user和group的设置为nobody，将其改为www-data
/usr/local/bin/php-fpm
