方法一、简单安装（通过yum）

1.安装epel-release

rpm -ivh 2.安装PHP7的rpm源rpm -Uvh 3.安装PHP7yum install php70w

方法二、编译安装

1.下载php7

wget -O php7.tar.gz 2.解压php7tar -xvf php7.tar.gz3.进入php目录cd php-7.0.44.安装依赖包# 直接复制下面一行（不包括本行）yum install libxml2 libxml2-devel openssl openssl-devel bzip2 bzip2-devel libcurl libcurl-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel gmp gmp-devel libmcrypt libmcrypt-devel readline readline-devel libxslt libxslt-devel5.编译配置（如果出现错误，基本都是上一步的依赖文件没有安装所致）

嫌麻烦的可以从这一步起参考PHP官方安装说明：

./configure \

--prefix=/usr/local/php \--with-config-file-path=/etc \--enable-fpm \--with-fpm-user=nginx \--with-fpm-group=nginx \--enable-inline-optimization \--disable-debug \--disable-rpath \--enable-shared \--enable-soap \--with-libxml-dir \--with-xmlrpc \--with-openssl \--with-mcrypt \--with-mhash \--with-pcre-regex \--with-sqlite3 \--with-zlib \--enable-bcmath \--with-iconv \--with-bz2 \--enable-calendar \--with-curl \--with-cdb \--enable-dom \--enable-exif \--enable-fileinfo \--enable-filter \--with-pcre-dir \--enable-ftp \--with-gd \--with-openssl-dir \--with-jpeg-dir \--with-png-dir \--with-zlib-dir \--with-freetype-dir \--enable-gd-native-ttf \--enable-gd-jis-conv \--with-gettext \--with-gmp \--with-mhash \--enable-json \--enable-mbstring \--enable-mbregex \--enable-mbregex-backtrack \--with-libmbfl \--with-onig \--enable-pdo \--with-mysqli=mysqlnd \--with-pdo-mysql=mysqlnd \--with-zlib-dir \--with-pdo-sqlite \--with-readline \--enable-session \--enable-shmop \--enable-simplexml \--enable-sockets \--enable-sysvmsg \--enable-sysvsem \--enable-sysvshm \--enable-wddx \--with-libxml-dir \--with-xsl \--enable-zip \--enable-mysqlnd-compression-support \--with-pear \--enable-opcache=no

编译时遇到错误：

PHP configure: error: mcrypt.h not found. Please reinstall libmcrypt.解决参考：

编译时遇到错误：configure: error: off_t undefined; check your library configuration 解决办法

解决参考：

6.正式安装

make && make install

7.配置环境变量

vi /etc/profile在末尾追加PATH=$PATH:/usr/local/php/binexport PATH执行命令使得改动立即生效source /etc/profile

8.配置php-fpm

cp php.ini-production /etc/php.inicp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.confcp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/www.confcp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpmchmod +x /etc/init.d/php-fpm

9.启动php-fpm

/etc/init.d/php-fpm start
