Installing on nginx as dynamic module
first you need to compile the module on same os like ubuntu 18.04 & same nginx version nginx 13
To know version of os & nginx
You can run this commands
nginx -v
//It shows current version of nginx
to know linux distribution version
lsab- v
//
installing
risky: you can also compile & install it on a live server.
just like upgrading nginx in live server. Just we need restart / reload.
if any errors we can solve it by nginx error log.
Configuring
You must understand the variables and the value there is pretty guidelines available at pagespeed module websites.
Gzip
css rewrite
js
compression level
minfiy or combine
Put critical css on head & remaining on footer or body
to you can view the live data in browser,
Monitoring
Error handling
lot of headaches, it adds a query string to and end page page url.
Make sure to block to avoid duplicate & thin content issues from Google,
WordPress caching plugin vs Google pagespeed module vs fast CGI cache
wordpress caching plugins utilizes php backend code, MySQL+p so there is a latency.
Pagespeed module directly handles &serves with help of nginx.
limitation of pagespeed module
only optimize/ rebuild the web pages according to Google pagespeed rules.
it rebuild s & stores as cache and serves cached pages.
Cached expiration time also important.
we have lot to understand & configure inorder to work with pagespeed module.
Tried for few months, upon migrating to new server not installed 3rd time.
Reason: profit/ time.
my website not drawing any users, so thought limited resources fine for limited visitors.

Remove / rename old compiled module
from

mv /etc/nginx/modules/ngx_pagespeed.so /etc/nginx/modules/ngx_pagespeed13.9.so
devtools
sudo apt-get install unzip gcc make libpcre3-dev zlib1g-dev
strongly recommend that you compile dynamic modules on a separate system, which we refer to here as the “build environment

Troubleshooting
PageSpeed Serf fetch failure rate extremely high; only 14 of 31 recent fetches fully successful; is fetching working?
pagespeed: rollback gzip, explicit configuration in /etc/nginx/nginx.conf:99
nginx.conf:99 gzip on;
mod_pagespeed automatically enables mod_deflate for compression.

View Pagespeed statistics
You can view Pagespeed statics by poinitng your browser to http://example.com/ngx_pagespeed_statistics
Disable Pagespeed temporary
You can disable pagespeed temporary by using this url: http://example.com/?PageSpeed=off

ou can build ngx_pagespeed by using –add-dynamic-module= instead of using –add-module=.
So you would use something like:
./configure –add-dynamic-module=/path/to/ngx_pagespeed
After running make and make install the dynamic ngx_pagespeed.so module should be located in the modules directory which resides in parallel to sbin where the nginx binary lives.
Subsequently you should be able to load ngx_pagespeed as a dynamic module by adding the following (early on) to the main context in nginx.conf:
load_module “modules/ngx_pagespeed.so”;
Just like pagespeed module letsencrypt SSL migration not possible. You may look at this.
