一.下载php-7.0.5
http://cn2.php.net/distributions/php-7.0.5.tar.gz
二.解压安装:
# tar zxvf php-7.0.5.tar.gz
# cd php-7.0.5
配置
#./configure –prefix=/usr/local/php7 –with-curl –with-freetype-dir –with-gd –with-gettext –with-iconv-dir –with-kerberos –with-libdir=lib64 –with-libxml-dir –with-mysqli –with-openssl –with-pcre-regex –with-pdo-mysql –with-pdo-sqlite –with-pear –with-png-dir –with-xmlrpc –with-xsl –with-zlib –enable-fpm –enable-bcmath –enable-libxml –enable-inline-optimization –enable-gd-native-ttf –enable-mbregex –enable-mbstring –enable-opcache –enable-pcntl –enable-shmop –enable-soap –enable-sockets –enable-sysvsem –enable-xml –enable-zip
/*mysqlnd
./configure –prefix=/usr/local/php7 –with-curl –with-freetype-dir –with-gd –with-gettext –with-iconv-dir –with-kerberos –with-libdir=lib64 –with-libxml-dir –with-mysqli=mysqlnd –with-openssl –with-pcre-regex –with-pdo-mysql=mysqlnd –with-pdo-sqlite –with-pear –with-png-dir –with-xmlrpc –with-xsl –with-zlib –enable-fpm –enable-bcmath –enable-libxml –enable-inline-optimization –enable-gd-native-ttf –enable-mbregex –enable-mbstring –enable-opcache –enable-pcntl –enable-shmop –enable-soap –enable-sockets –enable-sysvsem –enable-xml –enable-zip –enable-mysqlnd
*/
如果出现错误安装对应模块
# yum -y install libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel MySQL pcre-devel
# yum -y install curl-devel
# yum -y install libxslt-devel
三.安装
#make && make install
四.配置文件
# cp php.ini-development /usr/local/php7/lib/php.ini
# 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
# cp -R ./sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
需要注意的是php7中www.conf这个配置文件配置phpfpm的端口号等信息,如果你修改默认的9000端口号需在这里改,再改nginx的配置启动
# /etc/init.d/php-fpm
五.配置OPcache
官网地址:http://php.net/opcache
使用下列推荐设置来获得较好的 性能:
opcache.memory_consumption=128
opcache.interned_strings_buffer=8
opcache.max_accelerated_files=4000
opcache.revalidate_freq=60
opcache.fast_shutdown=1
opcache.enable_cli=1
你也可以禁用 opcache.save_comments 并且启用 opcache.enable_file_override。 需要提醒的是,在生产环境中使用上述配置之前,必须经过严格测试。 因为上述配置存在一个已知问题,它会引发一些框架和应用的异常, 尤其是在存在文档使用了备注注解的时候。
#vi /usr/local/php7/etc/php.ini
# 加入
zend_extension=/usr/local/php7/lib/php/extensions/no-debug-non-zts-20141001/opcache.so
重启
# killall php-fpm
# /etc/init.d/php-fpm
也可以使用gits上提供的代码直观查看

七,其它php7优化
1.HugePage
首先在系统中开启HugePages, 然后开启Opcache的huge_code_pages.
#sysctl vm.nr_hugepages=512
然后在php.ini中加入:
opcache.huge_code_pages=1
2.Opcache file cache
在php.ini中加入:
opcache.file_cache=/tmp
