Pagespeed module install, configure, monitor, errors ft nginx &apache

Installing Pagespeed module 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.

Remove / rename old compiled module

from

mv objs/ngx_pagespeed.so objs/ngx_pagespeed13.9so

mv /etc/nginx/modules/ngx_pagespeed.so /etc/nginx/modules/ngx_pagespeed13.9.so

Install 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

same os and same nginx.

compiling Pagespeed module with latest nginx

check version

nginx -v

nginx version: nginx/1.15.2

Download the same version of nginx to compile already covered above.

create directory

mkdir -p /etc/new/nginx/

cd /etc/new/nginx/

download latest nginx

wget -qO – http://nginx.org/download/nginx-1.15.2.tar.gz | tar zxfv –

wget http://nginx.org/download/nginx-1.15.2.tar.gz

tar -xzvf nginx-1.15.2.tar.gz

Download Pagespeed Module

check latest release stable here.

check latest version and find the version number set it as variable.

Set environment variable

Include only the numeric part of the version string, not the ‑stable or ‑beta suffix.

assigning value to airbale

$ NPS_VERSION=numeric-part-of-version-string

download module

NPS_VERSION=1.13.35.2-stable

wget https://github.com/apache/incubator-pagespeed-ngx/archive/v${NPS_VERSION}.zip

unzip v${NPS_VERSION}.zip

nps_dir=$(find . -name “*pagespeed-ngx-${NPS_VERSION}” -type d)

cd “$nps_dir”

NPS_RELEASE_NUMBER=${NPS_VERSION/beta/}

NPS_RELEASE_NUMBER=${NPS_VERSION/stable/}

psol_url=https://dl.google.com/dl/page-speed/psol/${NPS_RELEASE_NUMBER}.tar.gz

[ -e scripts/format_binary_url.sh ] && psol_url=$(scripts/format_binary_url.sh PSOL_BINARY_URL)

wget ${psol_url}

tar -xzvf $(basename ${psol_url})

// HInt: if failed check https://dl.google.com/dl/page-speed/psol/1.13.35.1-stable.tar.gz

You will be here

/incubator-pagespeed-ngx-1.13.35.1-stable

$ cd ../nginx-1.15.2

//make sure to rename if already loaded module

ls /etc/nginx/modules/

mv /etc/nginx/modules/ngx_pagespeed.so /etc/nginx/modules/ngx_pagespeed13.9.so

$ ./configure –add-dynamic-module=../ngx_pagespeed-${NPS_VERSION} –with-compat

adding module in ../ngx_pagespeed-1.13.35.2-stable

Copying module & loading module in nginx.conf

sudo cp objs/ngx_pagespeed.so /etc/nginx/modules/

ls /etc/nginx/modules/

/usr/lib/nginx/modules

nano /etc/nginx/nginx.conf

nginx.con top pf http

load_module modules/ngx_pagespeed.so;

nginx -t

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok

nginx: configuration file /etc/nginx/nginx.conf test is successful

sudo nginx -s reload

nginx -V

at server block

Configuring

You must understand the variables and the value there is pretty guidelines available at pagespeed module websites.

Gzip

css rewrite

compression level

minify or combine

Put critical css on head & remaining on footer or body

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 fastCGI 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 in order 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.

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

pagespeed EnableFilters responsive_images,resize_images;

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”;
