0，安裝 php-7.1.6 依賴包

# yum groupinstall "Development tools" "Desktop Platform Development"
# yum -y install openssl-devel libcurl-devel libmcrypt libmcrypt-devel bzip2-devel

1，編譯安裝php 7.1.6

## 如果需要加入 pgsql擴展 ，則必須先安裝好 postgresql

# wget http://cn2.php.net/get/php-7.1.6.tar.gz/from/this/mirror
wget http://hk1.php.net/get/php-7.1.6.tar.gz/from/this/mirror
# tar xf php-7.1.6.tar.gz 
# cd php-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
# make && make install

# cp /usr/local/src/php-7.1.6/php.ini-production /usr/local/php-7.1.6/etc/php.ini## 在編譯好的源碼包目錄下復制 php 的配置文件
# cp /usr/local/php-7.1.6/etc/php-fpm.conf.default /usr/local/php-7.1.6/etc/php-fpm.conf ## 復制php-fpm 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## 復制配置文件
# vim /usr/local/php-7.1.6/etc/php-fpm.d/www.conf    ##修改 php-fpm 模塊使用用戶和組
user = nginx
group = nginx
# cp /usr/local/src/php-7.1.6/sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm## 在編譯好的源碼包目錄下復制 php-fpm 啟動腳本到 /etc/init.d/
# chmod 755 /etc/rc.d/init.d/php-fpm
# chkconfig --add php-fpm
# chkconfig --list php-fpm
# vim /etc/profile.d/php.sh ## 導出命令搜索路徑到環境變量
export  php_home=/usr/local/php-7.1.6/bin/
export  PATH=$PATH:$php_home
# . /etc/profile.d/php.sh

2，安裝 memcached 緩存擴展

# yum install cyrus-sasl cyrus-sasl-devel -y## memcached的依賴包
# pecl install memcached
# wget https://launchpad.net/libmemcached/1.0/1.0.18/+download/libmemcached-1.0.18.tar.gz## php-memcached 擴展依賴庫
# tar xf libmemcached-1.0.18.tar.gz 
# cd libmemcached-1.0.18
# ./configure --prefix=/usr/local/libmemcached-1.0.18 --with-memcached
# make && make install
#/usr/local/php-7.1.6/bin/pecl install memcached##前提是已經編譯安裝好的php中有pear命令包

libmemcached directory [no] : 填入剛才libmemcached的編譯安裝目錄地址

# echo "extension=memcached.so" >> /usr/local/php-7.1.6/etc/php.ini    ##在php配置中追加memcached模塊
