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
