yum方式安装php+nginx，yum方式phpnginx

centos yum方式安装php+nginx

安装nginx

yum install nginx
# 配置：/etc/nginx/nginx.conf
# 常用命令
#启动
systemctl start nginx
#停止
systemctl stop nginx
#重启
systemctl restart nginx
#平滑重启
systemctl reload nginx

安装php

1、添加php的yum软件仓库

CentOS/RHEL 7.x:
rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
如果是centos6，那么执行以下代码：
CentOS/RHEL 6.x:
rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-6.noarch.rpm
rpm -Uvh https://mirror.webtatic.com/yum/el6/latest.rpm

2、开始安装php

1. 查询yun软件中php7.1的版本
   yum list | grep php71w
2. 安装php
   yum install php71w php71w-fpm php71w-cli php71w-common php71w-devel php71w-gd php71w-pdo php71w-mysql php71w-mbstring php71w-bcmath
   #相关配置：
   # 基础配置 /etc/php.ini
   #扩展：/etc/php.d/
   # php-fpm :  /etc/php-fpm.conf  /etc/php-fpm.d/www.conf
   
3. 安装php几个重要的扩展
  1) redis扩展
  yum install php71w-pecl-redis 
  2) redis序列化扩展
  yum install  php71w-pecl-igbinary
  3) memcached 扩展
  yum install php71w-pecl-memcached
  # yum 方法安装的扩展自动加入到配置文件中，故不需要另外加配置
  #扩展的配置目录 /etc/php.d/*
 4. php 服务常用命令
 #启动
systemctl start php-fpm
#停止
systemctl stop php-fpm
#重启
systemctl restart php-fpm
#平滑重启
systemctl reload php-fpm
