[PHP] – 安装优化 – 安装PHP7

一、简单安装 通过yum

1.安装epel-release

1. 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

1. rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

3.安装PHP7

1. yum install php70w

二、编译安装

1.下载php7

1. wget -O php7.tar.gz http://cn2.php.net/get/php-7.0.4.tar.gz/from/this/mirror

2.解压php7

1. tar -xvf php7.tar.gz

3.进入php目录

1. cd php-7.0.4

4.安装依赖包

1. # 直接复制下面一行（不包括本行）
2. 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）

1. vim /etc/profile

在末尾追加

1. export PATH=/usr/local/php/bin:$PATH

执行命令使得改动立即生效

1. source /etc/profile

8.配置php-fpm 
需要在安装软件包目录

1. cp php.ini-production /etc/php.ini
2. cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf
3. cp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/www.conf
4. cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
5. chmod +x /etc/init.d/php-fpm

启动php-fpm

1. /etc/init.d/php-fpm start
