Centos7 安装 PHP7最新版的详细教程
方法一、简单安装（通过yum）
1.安装epel-release
rpm -ivh http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm
2.安装PHP7的rpm源
rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
3.安装PHP7
yum install php70w
方法二、编译安装
1.下载php7
wget -O php7.tar.gz http://cn2.php.net/get/php-7.1.1.tar.gz/from/this/mirror
2.解压php7
tar -xvf php7.tar.gz
3.进入php目录
cd php-7.0.4
4.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-devel
5.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：http://php.net/manual/zh/install.unix.nginx.php
./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
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
