Compiling Nginx on production. How to do it without down time.

[Quintin Par]

Hi all,

I run vanilla builds of Nginx from the Nginx centos repo.

But recently I’ve started to realize the need for additional modules in
Nginx like Nginx status, openresty, lua etc.

Now this will mean that my vanilla Nginx with

nginx version: nginx/1.0.12

built by gcc 4.4.4 20100726 (Red Hat 4.4.4-13) (GCC)

TLS SNI support enabled

configure arguments: --prefix=/etc/nginx/ --sbin-path=/usr/sbin/nginx
--conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log
--http-log-path=/var/log/nginx/access.log --pid-path=/var/run/nginx.pid
--lock-path=/var/run/nginx.lock
--http-client-body-temp-path=/var/cache/nginx/client_temp
--http-proxy-temp-path=/var/cache/nginx/proxy_temp
--http-fastcgi-temp-path=/var/cache/nginx/fastcgi_temp
--http-uwsgi-temp-path=/var/cache/nginx/uwsgi_temp
--http-scgi-temp-path=/var/cache/nginx/scgi_temp --user=nginx --group=nginx
--with-http_ssl_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_gzip_static_module --with-http_random_index_module
--with-http_secure_link_module --with-http_stub_status_module --with-mail
--with-mail_ssl_module --with-file-aio --with-ipv6 --with-cc-opt='-O2 -g'

will have to be recompiled.

How can I do it with minimal downtime on my prod machine?
