PHP7正式版发布啦， 之前没有安装过的，都来安装试一试 。 即将发布的ThinkPHP5 在PHP7环境下也完全兼容， 佩服鸟哥把兼容性做得这么好[good]
快速编译安装PHP7步骤：
第一步： 安装必要一些依赖
# 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： 下载php7源码包
# 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： 编译安装
# ‘./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
# 启动
/etc/init.d/php7-fpm start
# 查看PHP版本
/usr/local/php7/bin/php -v
为了安全最好是去掉头信息 X-Powered-By: PHP/7.*.*
则修改 php.ini 文件 设置 expose_php = Off
vim /usr/local/php7/etc/php.ini
找到 expose_php = On
改为 expose_php = Off
