nginx平滑重启与平滑升级的方法

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
