CentOS7下安装PHP7

安装Composer

前一篇CentOS7下PHP环境搭建直接用

yum

安装php，优点是方便快捷，但缺点是版本太低，安装完成后是

PHP 5.4.16

的，在使用laravel框架时会报错版本太低，于是想着安装PHP7。

（1）安装必须的依赖

yum install -y \

gcc-c++ autoconf \

libjpeg libjpeg-devel libpng \

libpng-devel freetype freetype-devel \

libpng libpng-devel libxml2 libxml2-devel \

zlib zlib-devel glibc glibc-devel \

glib2 glib2-devel bzip2 bzip2-devel \

ncurses curl openssl-devel \

gdbm-devel db4-devel libXpm-devel \

libX11-devel gd-devel gmp-devel \

readline-devel libxslt-devel \

expat-devel xmlrpc-c xmlrpc-c-devel \

libicu-devel libmcrypt-devel \

libmemcached-devel\

httpd-devel

（2）下载、解压、安装PHP7

在官网可以看下最新版本的版本号，当前最新稳定版是7.0.8

cd /usr/src/

wget http://cn2.php.net/distributions/php-7.0.8.tar.gz

tar -xzvf php-7.0.8.tar.gz

cd php-7.0.8

编译，具体参数就暂时不解释了

./configure –prefix=/usr/local/php7 \

–with-mysql-sock –with-mysqli \

–enable-fpm –enable-soap \

–with-libxml-dir –with-openssl \

-with-apxs2 \

–with-mcrypt –with-mhash \

–with-pcre-regex –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-pdo-mysql \

–with-zlib-dir –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-intl

安装

make

make install

安装完后PHP7就已经安装在/usr/local/php7目录下了，将它添加到系统路径中。

ln -sf /usr/local/php7/bin/php /usr/local/bin/php

这时候用

php -v

发现还是显示旧版本，用whereis 找一下，发现还有一个软链

/usr/bin/php

，同样替换掉：

ln -sf /usr/local/php7/bin/php /usr/bin/php
