（1）源码包下载
百度云下载地址：https://pan.baidu.com/s/1xH7aiGYaX62wij4ul5P-ZQ
提取码：m9zc
（2）安装php依赖组件:
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
（3）解压源码包并进入目录配置
cp -frp /usr/lib64/libldap* /usr/lib/
./configure --prefix=/usr/local/php --with-apxs2=/usr/local/apache2/bin/apxs --with-config-file-path=/usr/local/php/etc --enable-mysqlnd --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd --enable-pdo --with-iconv-dir --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir= --enable-xml --enable-session --disable-rpath --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --enable-mbregex --enable-mbstring --enable-intl --enable-pcntl --enable-ftp --with-gd --with-openssl --with-mhash --enable-pcntl --enable-sockets --with-xmlrpc --enable-zip --enable-soap --with-gettext --disable-fileinfo --enable-opcache --enable-maintainer-zts --with-xsl --enable-tokenizer
（4）编译与安装
make -j 4 && make install
（5）完成安装后配置php.ini文件：
cp /usr/local/src/php-7.2.12/php.ini-development /usr/local/php/etc/php.ini
修改 php.ini 相关参数：
mysqli.default_socket = /usr/local/mysql/mysql.sock ;将php与mysql关联 date.timezone = Asia/Shanghai ;时区设置 expose_php = Off ;隐藏 “X-Powered-By: PHP/5.2.13” 这个信息。 short_open_tag = ON ;开启短标签 max_execution_time = 300 ;脚本的最大执行时间 max_input_time = 300 memory_limit = 128M post_max_size = 32M
（6）验证安装的模块
/usr/local/php/bin/php –m
(7)关联php与apache服务
编辑Apache配置文件，使httpd支持php网页解析:
添加以下两行内容：
AddType application/x-httpd-php .php
AddType application/x-httpd-php-source .phps
修改以下内容：
DirectoryIndex index.php index.html ;此处注意，php文件必须放前面，优先读取
至此，PHP已完全安装。
