How to smoothly upgrade nginx after compiling and installing nginx

After nginx is compiled and installed and used for a period of time, if you find that the current version has vulnerabilities or needs new functions, you need to upgrade the current nginx version, but it should not affect normal use. Therefore, you need to smoothly upgrade nginx and update it to the latest version.

This article demonstrates the process of upgrading nginx-1.13.6 to nginx-1.13.12, which is also applicable to other versions.

1. Download the new version of nginx

Download page: http://nginx.org/en/download.html

wget -c http://nginx.org/download/nginx-1.13.12.tar.gz

2. Get the configuration of the old version of nginx

Check the current version: /usr/local/nginx/sbin/nginx -v

View the current configuration: /usr/local/nginx/sbin/nginx -V

[root@zixuephp nginx-1.13.6]# /usr/local/nginx/sbin/nginx -v
nginx version: nginx/1.13.6
[root@zixuephp nginx-1.13.6]# /usr/local/nginx/sbin/nginx -V
nginx version: nginx/1.13.6
built by gcc 4.8.5 20150623 (Red Hat 4.8.5-16) (GCC) 
built with OpenSSL 1.0.2k-fips 26 Jan 2017
TLS SNI support enabled
configure arguments: --prefix=/usr/local/nginx --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_v2_module --with-http_gzip_static_module --with-http_sub_module --with-pcre --with-http_ssl_module

3. Unzip the new version of nginx source package

tar -xzvf nginx-1.13.12.tar.gz
cd nginx-1.13.12

4. Configuration before recompiling the new version

The configuration here is the same as the old version: /usr/local/nginx/sbin/nginx -V

5. Compile and generate the objs directory, enter the directory, and replace nginx

make

After compiling, you can see that there is an objs directory through ls

[root@zixuephp nginx-1.13.12]# ls
auto CHANGES CHANGES.ru conf configure contrib html LICENSE Makefile man objs README src
[root@zixuephp nginx-1.13.12]#

Enter the objs directory and replace the old version of the nginx main program (be sure to back up before operating here to avoid mistakes)

[root@zixuephp objs]#mv nginx /usr/local/nginx/sbin/nginx

6. Smooth upgrade

make upgrade

7. Upgrade successfully, check the version

[root@zixuephp nginx-1.13.12]# /usr/local/nginx/sbin/nginx -v
nginx version: nginx/1.13.12
[root@zixuephp nginx-1.13.12]# /usr/local/nginx/sbin/nginx -V
nginx version: nginx/1.13.12
built by gcc 4.8.5 20150623 (Red Hat 4.8.5-16) (GCC) 
built with OpenSSL 1.0.2k-fips 26 Jan 2017
TLS SNI support enabled
configure arguments: --prefix=/usr/local/nginx --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_v2_module --with-http_gzip_static_module --with-http_sub_module --with-pcre --with-http_ssl_module

Before upgrading, be sure to back up the nginx program, website and other files in advance to avoid errors.
