1、开始之前首先查看当前的使用版本以及编译时的参数:
[root@www ~]# /usr/local/nginx/sbin/nginx -V nginx version: nginx/1.12.2 built by gcc 4.4.7 20120313 (Red Hat 4.4.7-23) (GCC) built with OpenSSL 1.0.1e-fips 11 Feb 2013 TLS SNI support enabled configure arguments: --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module
将编译参数复制出来,编译新版本的时候会用到。
2、下载新版本:http://nginx.org/en/download.html
cd nginx-1.14.0 ./configure --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module make
3、执行完成之后,不需要make install ,备份原来的二进制启动文件,然后将新版的启动文件拷贝过去
mv /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx.bak [root@www nginx-1.14.0]# cp objs/nginx /usr/local/nginx/sbin/nginx
4、测试一下复制过来的文件是否生效:
[root@www nginx-1.14.0]# /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 successful
5、发送USR2信号给nginx master 进程(nginx服务接收到USR2信号后,首先会将旧的nginx.pid文件添加后缀.oldbin,变为nginx.pid.oldbin,然后执行新版本的二进制文件启动服务,如果新的服务启动成功,系统中将有新旧两个Nginx服务共同提供web服务)
kill -USR2 `cat /usr/local/nginx/logs/nginx.pid` [root@www nginx-1.14.0]# ps -ef | grep nginx root 22644 1 0 23:30 ? 00:00:00 nginx: master process /usr/local/nginx/sbin/nginx www 22648 22644 0 23:30 ? 00:00:00 nginx: worker process root 25784 22644 0 23:47 ? 00:00:00 nginx: master process /usr/local/nginx/sbin/nginx www 25789 25784 0 23:47 ? 00:00:00 nginx: worker process
6、通过发送WINCH信号(平缓停止worker process)和QUIT信号(平缓停止Nginx服务)停止旧的Nginx服务进程
kill -WINCH `cat /usr/local/nginx/logs/nginx.pid.oldbin` kill -QUIT `cat /usr/local/nginx/logs/nginx.pid.oldbin`
7、升级完成,最后看一下nginx版本:
/usr/local/nginx/sbin/nginx -v nginx version: nginx/1.14.0
