第一步： 安裝必要一些依賴
# yum install php-mcrypt libmcrypt libmcrypt-devel libxml2-devel openssl-devel libcurl-devel libjpeg.x86_64 libpng.x86_64 freetype.x86_64 libjpeg-devel.x86_64 libpng-devel.x86_64 freetype-devel.x86_64 libjpeg-turbo-devel libmcrypt-devel mysql-devel -y第二步： 下載php7源碼包
# wget http://59.108.200.35/files/1164000003730786/cn2.php.net/distributions/php-7.0.0.tar.gz
# tar -xzvf php-7.0.0.tar.gz
# cd php-7.0.0第三步： 編譯安裝
# ./configure --prefix=/usr/local/php7 --with-config-file-path=/usr/local/php7/etc --with-mcrypt=/usr/include --enable-mysqlnd --with-gd --with-iconv --with-zlib --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --enable-mbregex --enable-fpm --enable-mbstring --enable-ftp --enable-gd-native-ttf --with-openssl --enable-pcntl --enable-sockets --with-xmlrpc --enable-zip --enable-soap --with-gettext --with-curl --with-jpeg-dir --with-freetype-dir --with-mysqli --enable-embedded-mysqli --with-pdo-mysql
# make
# make install第四步： 配置php
cp php.ini-production /usr/local/php7/etc/php.ini
cp sapi/fpm/init.d.php-fpm /etc/init.d/php7-fpm
chmod +x /etc/init.d/php7-fpm
cp /usr/local/php7/etc/php-fpm.conf.default /usr/local/php7/etc/php-fpm.conf
cp /usr/local/php7/etc/php-fpm.d/www.conf.default /usr/local/php7/etc/php-fpm.d/www.conf
vim /usr/local/php7/etc/php.ini# 加入
zend_extension=/usr/local/php7/lib/php/extensions/no-debug-non-zts-20151012/opcache.so
# 啓動
/etc/init.d/php7-fpm start
# 查看PHP版本
/usr/local/php7/bin/php -v爲了安全最好是去掉頭信息 X-Powered-By: PHP/7.*.*
則修改 php.ini 文件 設置 expose_php = Off
vim /usr/local/php7/etc/php.ini
找到 expose_php = On
改爲 expose_php = Off
