1、上传新版本的源码包（旧版本是1.14.2,新版本是1.16.0）
[root@localhost ~]# ls anaconda-ks.cfg nginx-1.14.2.tar.gz nginx-1.16.0.tar.gz
2、解压，解压到原路径
[root@localhost ~]# tar -xf nginx-1.16.0.tar.gz -C /usr/src/
3、获取旧版本的编译安装信息
[root@localhost ~]# nginx -V nginx version: nginx/1.14.2 built by gcc 4.8.3 20140911 (Red Hat 4.8.3-9) (GCC) built with OpenSSL 1.0.1e-fips 11 Feb 2013 TLS SNI support enabled configure arguments: --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_stub_status_module --with-http_ssl_module --with-http_flv_module --with-http_gzip_static_module
4、切换到解压路径下编译新版本的源码包，不需要执行安装（不需要执行make install）
[root@localhost ~]# cd /usr/src/nginx-1.16.0/ [root@localhost nginx-1.16.0]# ./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_stub_status_module --with-http_ssl_module --with-http_flv_module --with-http_gzip_static_module && make
5、备份二进制文件，用新版nginx替换旧版nginx
[root@localhost ~]# mv /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx.old [root@localhost ~]# ls /usr/local/nginx/sbin/ nginx.old [root@localhost ~]# cp /usr/src/nginx-1.16.0/objs/nginx /usr/local/nginx/sbin/ [root@localhost ~]# ls /usr/local/nginx/sbin/ nginx nginx.old
6、查看配置文件，确保正确
[root@localhost ~]# 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
7、发送USR2信号
向主进程（master）发送USR2信号，Nginx会启动一个新版本的master进程和对应工作进程，和旧版一起处理请求
[root@localhost ~]# ps aux | grep nginx | grep -v grep root 4108 0.0 0.2 45028 1152 ? Ss 16:58 0:00 nginx: master process /usr/local/nginx/sbin/nginx nginx 4109 0.0 0.4 45456 2012 ? S 16:58 0:00 nginx: worker process [root@localhost ~]# kill -USR2 4108 [root@localhost ~]# ps aux | grep nginx | grep -v grep root 4108 0.0 0.2 45028 1316 ? Ss 16:58 0:00 nginx: master process /usr/local/nginx/sbin/nginx nginx 4109 0.0 0.4 45456 2012 ? S 16:58 0:00 nginx: worker process root 6605 0.5 0.6 45196 3364 ? S 17:02 0:00 nginx: master process /usr/local/nginx/sbin/nginx nginx 6607 0.0 0.3 45624 1756 ? S 17:02 0:00 nginx: worker process
8、发送WINCH信号
向旧的Nginx主进程（master）发送WINCH信号，它会逐步关闭自己的工作进程（主进程不退出），这时所有请求都会由新版Nginx处理
[root@localhost ~]# kill -WINCH 4108 [root@localhost ~]# ps aux | grep nginx | grep -v grep root 4108 0.0 0.2 45028 1320 ? Ss 16:58 0:00 nginx: master process /usr/local/nginx/sbin/nginx root 6605 0.0 0.6 45196 3364 ? S 17:02 0:00 nginx: master process /usr/local/nginx/sbin/nginx nginx 6607 0.0 0.3 45624 1756 ? S 17:02 0:00 nginx: worker process
9、发送QUIT信号
升级完毕，可向旧的Nginx主进程（master）发送（QUIT、TERM、或者KILL）信号，使旧的主进程退出
[root@localhost ~]# kill -QUIT 4108 [root@localhost ~]# ps aux | grep nginx | grep -v grep root 6605 0.0 0.6 45196 3364 ? S 17:02 0:00 nginx: master process /usr/local/nginx/sbin/nginx nginx 6607 0.0 0.4 45624 2056 ? S 17:02 0:00 nginx: worker process
10、验证nginx版本号，并访问测试
[root@localhost ~]# curl -I 127.0.0.1 HTTP/1.1 200 OK Server: nginx/1.16.0 Date: Sun, 18 Aug 2019 13:34:07 GMT Content-Type: text/html Content-Length: 612 Last-Modified: Sun, 18 Aug 2019 13:26:08 GMT Connection: keep-alive ETag: "5d5951f0-264" Accept-Ranges: bytes
