nginx modules list (enable, disable, upgrade, install dynamic module)

how to view loaded modules in nginx

command

nginx-V

it will list nginx version with compiled modules, while installing a module.

static modules:

installed along with nginx install, no way to disable or enable like Apache.

dynamic modules:

available in nginx plus and newer nginx version.

step 1: compile nginx module in same environment like production server.

2nd: test server: used to compile the module. after compiled module available,

3rd: we have to copy the module end .so

/etc/nginx/modules (or other path).

and include in nginx.conf

Loadmodule /path/to-module

nginx module instead of error fix.

if you are using this dynamic module, you will get this (,upgrade failed).

because dynamic module has to recompile along with new nginx version.

/etc/nginx/modules/ngx_http_geoip_module.so

don’t restart or reboot(if nginx unable to start until problem fixed)

temporary fix: unload module by commenting in nginx.conf & start the upgrade

permanent fix: recompile the module with new nginx version /current nginx version.

how to install dynamic module in nginx?

check your nginx version

nginx -v

or upgrade to latest version.

then type nginx -v

download latest version of nginx it should match current production server

#1 download nginx

wget -qO – http://nginx.org/download/nginx-1.18.10.tar.gz | tar zxfv –

#2 download dynamic module

git clone https://github.com/perusio/nginx-hello-world-module.git

#2.1 install build tools if not already

sudo apt-get install unzip gcc make libpcre3-dev zlib1g-dev

#3 compile dynamic module

company & make modules command

cd nginx-1.11.10/

./configure –with-compat –add-dynamic-module=../nginx-hello-world-module

$ make modules

#4. verify the module & copy to nginx directory

by default its available in objs subdirectory

ls objs/*.so

objs/ngx_http_hello_world.so

cp objs/ngx_http_hello_world.so /etc/nginx/modules

#5 upgrade nginx if not done early

service nginx upgrade

#6 edit nginx.conf

loadmodule

,& reload nginx

if you are building it in production server.

it’s better to compile in build environment & copy to production server.

mycase: I already did in production server (but downtime important in case of high traffic)

enable & disable dynamic module in nginx

edit conf file

comment or uncomment

reload nginx server.

also read pagespeed module in nginx as dynamic.

module configuration file would be in nginx.conf or

conf.d modulename.conf

nginx modules location

static modules

–modules-path=/usr/lib/nginx/modules

dynamic module /etc/nginx/modules (shortcut to usr/lib/nginx)

Install nginx without unnecessary modules

Note: every module has some features, and runs in memory (so uninstall unnecessary modules or install with required module)

–without-module

how to enable brotli compression in nginx

$ apt-get install nginx-plus-module-brotli

edit nginx.conf

at top:

load_module modules/ngx_http_brotli_filter_module.so;
load_module modules/ngx_http_brotli_static_module.so;

configurations in .conf

same as gzip just replacewith brotil.

How do I see what modules are installed in nginx?

just run this command

sudo nginx -V

What are dynamic modules in nginx?

apache more mature you can add new module just by one click. but with nginx you have to recompile nginx.

to overcome this nginx plus added a new feature called dynamic module. compiled version of file with same linux and nginx server. we can enable disable any time.

i tried pagespeed nginx module. later removed.
