yum install epel-release -yyum update
安装依赖
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
cd /home/downloadgroupadd wwwuseradd -g www wwwwget http://am1.php.net/distributions/php-7.2.1.tar.gztar xvf php-7.2.1.tar.gzcd php-7.2.1
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 --with-mcrypt --with-libmbfl --enable-ftp --with-gd --enable-gd-jis-conv --enable-gd-native-ttf --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
若无报错执行下一步安装，如果编译过程中出现错误，根据报错安装依赖包，通常不会出现这种问题。
注意：–enable-gd-jis-conv 此参数会导致Zabbix中文字符乱码，建议取消。
开始安装：
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.inicp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.confcp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/www.conf
创建system系统单元文件php-fpm启动脚本：
vim /usr/lib/systemd/system/php-fpm.service
[Unit]Description=The PHP FastCGI Process ManagerAfter=syslog.target network.target[Service]Type=simplePIDFile=/usr/local/php/var/run/php-fpm.pidExecStart=/usr/local/php/sbin/php-fpm --nodaemonize --fpm-config /usr/local/php/etc/php-fpm.confExecReload=/bin/kill -USR2 $MAINPID[Install]WantedBy=multi-user.target
启动php-fpm服务并加入开机自启动：
systemctl enable php-fpm.servicesystemctl restart php-fpm.service
centos7+ 安装 php7.2
