附一：yum安装nginx

 　　# rpm -Uvh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm 

　　# yum info nginx

　　# yum install -y nginx

　　# systemctl start nginx

　　# systemctl enable nginx

附二：安装 nginx 也相当简单，查看官网说明文档 http://nginx.org/en/linux_packages.html#stable

　　 1）[root@localhost ~] vi /etc/yum.repos.d/nginx.repo

 　　2）复制如下内容到刚才新建的文件中

[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/7/$basearch/　　# 因为我的系统是centos7
gpgcheck=0
enabled=1

　　3）yum -y install nginx

　　4）yum start nginx

　　5）yum enable nginx

附三：ngnix修改配置文件支持php　　

server {
    listen         80;
    server_name    localhost;

    #charset koi8-r;
    #access_log  /var/log/nginx/host.access.log  main;

    root   /var/www/;    # 把root从localhost中拿出来，不然$document_root找不到会报404

    location / {
        index  index.php index.html index.htm;
    }

    #error_page  404              /404.html;

    # redirect server error pages to the static page /50x.html
    #
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /var/www/;
    }

    # proxy the PHP scripts to Apache listening on 127.0.0.1:80
    #
    #location ~ \.php$ {
    #    proxy_pass   http://127.0.0.1;
    #}

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    location ~* \.php$ {
        fastcgi_index   index.php;
        fastcgi_pass    127.0.0.1:9000;
        include         fastcgi_params;
        fastcgi_param   SCRIPT_FILENAME    $document_root$fastcgi_script_name;
        fastcgi_param   SCRIPT_NAME        $fastcgi_script_name;
    }

    # deny access to .htaccess files, if Apache's document root
    # concurs with nginx's one
    #
    #location ~ /\.ht {
    #    deny  all;
    #}
}

    

附四：修改/etc/php-fpm.d/www.conf  文件

user = nginx　　　＃　由apache改为nginx
; RPM: Keep a group allowed to write in log dir.
group = nginx    # 由apache改为nginx
