安装Nginx的方式有很多种，这里我们还是编译源码进行安装，使用下列命令：
$ wget http://nginx.org/download/nginx-1.6.2.tar.gz$ tar -zxvf nginx-1.6.2.tar.gz$ cd nginx-1.6.2$ ./configure --prefix=/usr/local/nginx$ make$ sudo make install
如果安装过程中出现如下错误
./configure: error: the HTTP rewrite module requires the PCRE library.You can either disable the module by using --without-http_rewrite_moduleoption, or install the PCRE library into the system, or build the PCRE librarystatically from the source with nginx by using --with-pcre=option.
则需要先安装pcre
$ sudo yum install pcre-devel
安装完成之后，我们的Nginx安装目录在/usr/local/nginx。 接下来修改nginx的配置文件(/usr/local/nginx/conf/nginx.conf)，使其能够处理php脚本。
worker_processes 1;events { worker_connections 1024;}http { include mime.types; default_type application/octet-stream; sendfile on; keepalive_timeout 65; server { listen 80; server_name _; root /vagrant; location / { index index.html index.htm index.php; } location /demo { index index.php; if (!-e $request_filename) { rewrite ^/demo/(.*)$ /demo/index.php?$1 last; break; } } error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } location ~ \.php$ { fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } }} 最后，启动Nginx时，需要先启动PHP-FPM。
$ sudo /usr/local/php/sbin/php-fpm$ sudo /usr/local/nginx/sbin/nginx
对于Nginx的重启以及关闭操作，可以使用以下命令
$ sudo /usr/local/nginx/sbin/nginx -s [reload|restart|stop]
而PHP-FPM，则麻烦一点，需要先使用ps -ef|grep php-fpm获取master process的进程ID， 再使用kill -USR2:
$ ps -ef|grep php-fpmroot 6221 1 0 02:17 ? 00:00:00 php-fpm: master process (/usr/local/php/etc/php-fpm.conf)nobody 6222 6221 0 02:17 ? 00:00:00 php-fpm: pool wwwnobody 6223 6221 0 02:17 ? 00:00:00 php-fpm: pool wwwvagrant 6233 1623 0 02:18 pts/0 00:00:00 grep php-fpm$ sudo kill -USR2 6221
注意:
-USR2参数为重启，-INT参数为关闭。
