安装php依赖组件（包含Nginx依赖）：
yum -y install wget vim pcre pcre-devel openssl openssl-devel libicu-devel gcc gcc-c++ autoconf libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel ncurses ncurses-devel curl curl-devel krb5-devel libidn libidn-devel openldap openldap-devel nss_ldap jemalloc-devel cmake boost-devel bison automake libevent libevent-devel gd gd-devel libtool* libmcrypt libmcrypt-devel mcrypt mhash libxslt libxslt-devel readline readline-devel gmp gmp-devel libcurl libcurl-devel openjpeg-devel
创建用户和组，并下载php安装包解压：
groupadd www useradd -g www www cd /usr/local/src wget https://www.php.net/distributions/php-7.3.9.tar.gz // 解压gz包 tar -zxvf php-7.3.9.tar.gz cd php-7.3.9
设置变量并开始源码编译：
cp -frp /usr/lib64/libldap* /usr/lib/
./configure --prefix=/usr/local/php --with-config-file-path=/usr/local/php/etc --enable-fpm --with-fpm-user=www --with-fpm-group=www --enable-mysqlnd --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd --enable-mysqlnd-compression-support --with-iconv-dir --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir --enable-xml --disable-rpath --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --enable-mbregex --enable-mbstring --enable-intl --enable-ftp --with-gd --enable-gd-jis-conv --with-openssl --with-mhash --enable-pcntl --enable-sockets --with-xmlrpc --enable-zip --enable-soap --with-gettext --disable-fileinfo --enable-opcache --with-pear --enable-maintainer-zts --with-ldap=shared --without-gdbm
开始安装：
// make -j命令介绍 http://www.360doc.com/content/16/1211/12/14838067_613760263.shtml make -j 4 && make install
完成安装后配置php.ini文件：
cp php.ini-development /usr/local/php/etc/php.ini cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf cp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/www.conf
