Detailed explanation of smooth upgrade of nginx

Recently, I feel that the company's nginx version is too low and we have to add a new nginx module, so the only way I can think of is to upgrade smoothly. Nginx updates really quickly. Recently, the old stable versions of nginx 0.8.55 and nginx 0.7.69 have been released. I prefer to use new versions of software, so I smoothly upgraded the original nginx-1.0.2 to the nginx-1.0.5 stable version. And record this process, hoping to be of some help to friends in need. 1. Check the current version before starting. # /usr/local/nginx/sbin/nginx -V nginx: nginx version: nginx/1.0.5 nginx: built by gcc 4.1.2 20080704 (Red Hat 4.1.2-50) nginx: TLS SNI support disabled nginx: configure arguments: --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-http_flv_module --with-cc-opt=-O3 --with-cpu-opt=opteron --with-http_gzip_static_module※ Pay attention to the redarea, which are previously compiled parameters. You will need to edit the new version immediately. 2. Download the new version: http://nginx.org/en/download.htmlThen: Unzip> Previous preparations> Compile# tar zxvf nginx-1.0.5.tar.gz # cd nginx-1.0.5 # ./configure --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-http_flv_module --with-cc-opt='-O3' --with-cpu-opt=opteron --with-http_gzip_static_module # make3. After execution, there is no need to make install, then rename /sbin/nginx to nginx.old# mv /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx.old4. Copy the compiled nginx file in the objs directory to the nginx installation directory sbin/# cp objs/nginx /usr/local/nginx/sbin/5. Test the new The effect of the copied file: # /usr/local/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 successful6. Let nginx modify the nginx.pid file to nginx.pid.oldbin, and then start nginx to achieve uninterrupted service operation# kill -USR2 `cat /usr/local/nginx/nginx.pid`(发送平滑升级信号将旧的nginx.pid文件添加后缀nginx.pid.oldbin)#kill -WINCH(平缓停止worker process) `cat /usr/local/nginx/nginx.pid.oldbin # kill -QUIT `cat /usr/local/nginx/nginx.pid.oldbin`7. The upgrade is completed, and finally in Take a look at the upgraded version# /usr/local/nginx/sbin/nginx -v nginx: nginx version: nginx/1.0.5

The above introduces the detailed explanation of smooth upgrade of nginx, including the relevant content. I hope it will be helpful to friends who are interested in PHP tutorials.
