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

安裝nginx
# yum install nginx

啟動nginx
# systemctl start nginx
# systemctl eable nginx

安裝php-fpm
# yum install php-fpm

啟動php-fpm
# systemctl start php-fpm
# systemctl eable php-fpm

修改nginx的default.conf
# vi /etc/nginx/conf.d/default.conf

=== default.conf ===
server {
    listen       80;
    server_name  localhost;

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

    location / {
        root   /var/www/html/;
        index  default.html default.php;
        try_files $uri $uri/ =404;
    }

    #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   /usr/share/nginx/html;
    }

    # 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$ {
        root   /var/www/html/;    
        try_files $uri =404;
        fastcgi_pass   unix:/var/run/php-fpm/php-fpm.sock;
        fastcgi_index  default.php;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include        fastcgi_params;
    }

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

修改php.ini
# vi /etc/php.ini
cgi.fix_pathinfo = 1 → cgi.fix_pathinfo = 0

修改www.conf
# vi /etc/php-fpm.d/www.conf
listen = 127.0.0.1:9000 → listen = /var/run/php-fpm/php-fpm.sock 
user = apache → user = nginx
group = apache → group = nginx

建立php-fpm.sock 並將所有者改為nginx
# touch /var/run/php-fpm/php-fpm.sock
# chown nginx:nginx php-fpm.sock

重新啟動php-fpm與nginx
# systemctl restart php-fpm
# systemctl restart nginx
