如何实现nginx平滑重启与平滑升级？

			平滑重启 kill -HUP `cat /usr/local/www/nginx/logs/nginx.pid`

			平滑升级nginx：

			cd /yujialin

			wget http://nginx.org/download/nginx-1.0.6.tar.gz

			tar zxvf nginx-1.0.6.tar.gz

			cd nginx-1.0.6

			/usr/local/www/nginx/sbin/nginx -V

			nginx: nginx version: nginx/1.0.4

			nginx: built by gcc 4.1.2 20080704 (Red Hat 4.1.2-50)

			nginx: configure arguments: --prefix=/usr/local/www/nginx --with-pcre=/yujialin/pcre-8.12 --with-http_stub_status_module --with-http_gzip_static_module

			得到编译参数

			./configure --prefix=/usr/local/www/nginx --with-pcre=/yujialin/pcre-8.12 --with-http_stub_status_module --with-http_gzip_static_module

			用上面这段编译

			然后make，千万别make install

			make完了 在objs目录下就多了个nginx，这个就是新版本的程序了

			mv /usr/local/www/nginx/sbin/nginx /usr/local/www/nginx/sbin/nginx-20110906

			cp objs/nginx /usr/local/www/nginx/sbin/nginx

			/usr/local/www/nginx/sbin/nginx -t

			nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok

			nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successfu

			make upgrade 执行升级

			执行完后 /usr/local/nginx/sbin/nginx -V

			nginx: nginx version: nginx/1.0.6

			nginx: built by gcc 4.1.2 20080704 (Red Hat 4.1.2-50)

			nginx: configure arguments: --prefix=/usr/local/www/nginx --with-pcre=/yujialin/pcre-8.12 --with-http_stub_status_module --with-http_gzip_static_module
