centos7 安装Nginx

1、nginx install: 
下载对应当前系统版本的nginx包(package)

# wget  http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm
建立nginx的yum仓库
# rpm -ivh nginx-release-centos-7-0.el7.ngx.noarch.rpm
下载并安装nginx
# yum install nginx
启动nginx服务
systemctl start nginx
配置
默认的配置文件在 /etc/nginx 路径下，使用该配置已经可以正确地运行nginx；如需要自定义，修改其下的 nginx.conf 等文件即可。
测试
在浏览器地址栏中输入部署nginx环境的机器的IP，如果一切正常，应该能看到如下字样的内容。

/etc/nginx/nginx.conf delete the comment #
###########################################
 location ~ \.php$ {
        root           html;
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  /usr/share/nginx/html/$fastcgi_script_name;
        include        fastcgi_params;
    }
###########################################

service nginx restart

2、redis install:

wget http://download.redis.io/releases/redis-3.0.0.tar.gz
tar zxvf redis-3.0.0.tar.gz
cd redis-3.0.0
./configure;make;make install
redis-server /etc/redis.conf

3、php-redis install:

error:the GPG keys listed for the "CentOS-7 - Updates - 163.com" repository are already insta
rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
cd /tmp
wget https://github.com/nicolasff/phpredis/zipball/master -O php-redis.zip
unzip php-redis.zip
解压后目录是：nicolasff-phpredis-21d6614
cd nicolasff-phpredis-21d6614
phpize
./configure
make
make install
确认一下so文件已经放置到正确目录
ll /usr/lib/php/modules/redis.so
vi /etc/php.ini 
add the following content.
extension=redis.so
[root@localhost phpredis-phpredis-fc673f5]# ll /usr/lib64/php/modules/redis.so

4、php-fpm install:

so as to parse the php by nginx
yum install php-fpm

5、start php-fpm nginx

vi /etc/php-fpm.conf daemonize = yes
php-fpm -c /etc/php.ini
service nginx restart

6、test nginx and php

http://localhost/test.php
<?php
echo phpinfo();
?>
