0，安装 PHP-7.1.6 依赖包

#yumgroupinstall"Developmenttools""DesktopPlatformDevelopment"
#yum-yinstallopenssl-devellibcurl-devellibmcryptlibmcrypt-develbzip2-devel

1，编译安装PHP 7.1.6

## 如果需要加入 pgsql扩展 ，则必须先安装好 postgresql

#wgethttp://cn2.PHP.net/get/PHP-7.1.6.tar.gz/from/this/mirror
wgethttp://hk1.PHP.net/get/PHP-7.1.6.tar.gz/from/this/mirror
#tarxfPHP-7.1.6.tar.gz
#cdPHP-7.1.6
#./configure--prefix=/usr/local/PHP-7.1.6\
--with-config-file-path=/usr/local/PHP-7.1.6/etc
--with-MysqLi--with-pdo-MysqL--with-pgsql=/usr/pgsql-9.4/\
--with-pdo-pgsql=/usr/pgsql-9.4/--with-openssl\
--with-zlib--with-bz2--with-gettext--with-curl\
--with-gd--with-mhash--with-xmlrpc--with-mcrypt\
--enable-xml--enable-bcmath--enable-shmop
--enable-sysvsem--enable-fpm--enable-mbstring\
--enable-pcntl--enable-sockets--enable-soap\
--enable-calendar--enable-dba--enable-exif\
--enable-ftp--with-freetype-dir--with-jpeg-dir--with-png-dir
#make&&makeinstall

##在编译好的源码包目录下复制PHP的配置文件
#cp/usr/local/src/PHP-7.1.6/PHP.ini-production/usr/local/PHP-7.1.6/etc/PHP.ini
##复制PHP-fpm配置文件
#cp/usr/local/PHP-7.1.6/etc/PHP-fpm.conf.default/usr/local/PHP-7.1.6/etc/PHP-fpm.conf
##复制www配置文件
#cp/usr/local/PHP-7.1.6/etc/PHP-fpm.d/www.conf.default/usr/local/PHP-7.1.6/etc/PHP-fpm.d/www.conf
#vim/usr/local/PHP-7.1.6/etc/PHP-fpm.d/www.conf##修改PHP-fpm模块使用用户和组
user=Nginx
group=Nginx
##在编译好的源码包目录下复制PHP-fpm启动脚本到/etc/init.d/
#cp/usr/local/src/PHP-7.1.6/sapi/fpm/init.d.PHP-fpm/etc/init.d/PHP-fpm
#chmod755/etc/rc.d/init.d/PHP-fpm
#chkconfig--addPHP-fpm
#chkconfig--listPHP-fpm
#vim/etc/profile.d/PHP.sh##导出命令搜索路径到环境变量
exportPHP_home=/usr/local/PHP-7.1.6/bin/
exportPATH=$PATH:$PHP_home
#./etc/profile.d/PHP.sh

2，安装 memcached 缓存扩展

#yuminstallcyrus-saslcyrus-sasl-devel-y##memcached的依赖包
#peclinstallmemcached
##PHP-memcached扩展依赖库
#wgethttps://launchpad.net/libmemcached/1.0/1.0.18/+download/libmemcached-1.0.18.tar.gz
#tarxflibmemcached-1.0.18.tar.gz
#cdlibmemcached-1.0.18
#./configure--prefix=/usr/local/libmemcached-1.0.18--with-memcached
#make&&makeinstall
##要使用pecl命令的前提是已经编译安装好的PHP中含有pear命令包，不过PHP-7.1.6中默认安装有pear
#/usr/local/PHP-7.1.6/bin/peclinstallmemcached

libmemcached directory [no] : 填入刚才libmemcached的编译安装目录地址

##pecl命令安装完memcached后会提示你将memcached.so追加到PHP.ini配置文件中
##在PHP配置中追加memcached模块
#echo"extension=memcached.so">>/usr/local/PHP-7.1.6/etc/PHP.ini
