CentOS 7 Nginx1.12.2平滑升级到新版本nginx-1.13.3

查看当前Nginx版本信息

[root@web ~]# /usr/local/nginx/sbin/nginx -V
nginx version: nginx/1.12.2
built by gcc 4.8.5 20150623 (Red Hat 4.8.5-28) (GCC) 
built with OpenSSL 1.1.0e  16 Feb 2017
TLS SNI support enabled
configure arguments: --prefix=/usr/local/nginx --user=nginx --group=nginx --with-pcre --with-openssl=/tmp/openssl-1.1.0e --with-http_ssl_module --with-http_v2_module --with-http_realip_module --with-http_addition_module --with-http_sub_module --with-http_dav_module --with-http_flv_module --with-http_mp4_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_random_index_module --with-http_secure_link_module --with-http_stub_status_module --with-http_auth_request_module --with-http_image_filter_module --with-mail --with-threads --with-mail_ssl_module --with-stream_ssl_module

下载nginx-1.13.3版本到/usr/local/下，解压并进入解压后的目录

[root@nginx ~]# cd /usr/local/
[root@nginx nginx-1.13.3]# wget http://nginx.org/download/nginx-1.13.3.tar.gz
[root@nginx nginx-1.13.3]# wget https://www.openssl.org/source/openssl-1.1.0e.tar.gz
[root@nginx nginx-1.13.3]# tar xf openssl-1.1.0e.tar.gz
[root@nginx nginx-1.13.3]# tar xf nginx-1.13.3.tar.gz
[root@nginx nginx-1.13.3]# cd nginx-1.13.3

查看nginx版本的时候，configure后面有一大串模块，这也是你第一次安装nginx时所指定的模块，升级的时候也要同时指定，也可以添加其他模块

[root@nginx nginx-1.13.3]# ./configure 
  --prefix=/usr/local/nginx 
  --user=nginx 
  --group=nginx 
  --with-pcre 
  --with-openssl=/tmp/openssl-1.1.0e 
  --with-http_ssl_module 
  --with-http_v2_module 
  --with-http_realip_module 
  --with-http_addition_module 
  --with-http_sub_module 
  --with-http_dav_module 
  --with-http_flv_module 
  --with-http_mp4_module 
  --with-http_gunzip_module 
  --with-http_gzip_static_module 
  --with-http_random_index_module 
  --with-http_secure_link_module 
  --with-http_stub_status_module 
  --with-http_auth_request_module 
  --with-http_image_filter_module 
  --with-mail 
  --with-threads 
  --with-mail_ssl_module 
  --with-stream_ssl_module 
 && make 

make完以后，不需要执行make install，否则会覆盖安装，nginx服务会出现各种问题

不中断nginx web服务器的正常运行称之为平滑升级，先重命名之前的nginx二进制文件

[root@nginx nginx-1.13.3]# mv /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx.bak

拷贝刚编译新生产的Nginx二进制文件到/usr/local/nginx/sbin/目录

[root@nginx nginx-1.13.3]# cp /usr/local/nginx-1.13.3/objs/nginx /usr/local/nginx/sbin/

开始执行升级命令

[root@web nginx-1.13.3]# make upgrade
/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
kill -USR2 `cat /usr/local/nginx/logs/nginx.pid`
sleep 1
test -f /usr/local/nginx/logs/nginx.pid.oldbin
kill -QUIT `cat /usr/local/nginx/logs/nginx.pid.oldbin`
