Hi,
In my application https://www.backbutton.org/
I placed the front end proxy server on the all new 64 Bit Rasperry Pi 4.
It is a wopping 64 bit processor with 8GM Ram running the on linux lsb_release Ubuntu 20.04 LTS.
I used the ubuntu 64 bit OS rather than Raspberry Pi OS because Raspberry Pi OS was pulling down a different version
of Ubuntu server Apache HTTPD , did not not include all the Ubuntu utilities.
I understand that when I startup the HTTPD using systemctl start apache2, it rises directly into RAM
occupying the massive 8 GM of volatile memory. Then it starts listening for urls in the I/O buffer.
I understand the HTTPD socket server with its text parser mod(s) performs quite fast when running in RAM.
I have tried out two different bits used talk to HTTPD with the back end business logic application server(s) .
The first bit I used is the mod_jk.
This is the bit which talks to each other
LoadModule jk_module path/to/mod_jk.so
AddModule mod_jk.c
JkWorkersFile /path/to/httpd/conf/workers.properties
The second bit I used is called mod_proxy.
this is the bit which talks to each other
<VirtualHost backbutton.org:443>
<Proxy balancer://mycluster>
BalancerMember http://127.0.0.1:8080
BalancerMember http://127.0.0.1:8081
</Proxy>
ProxyPreserveHost On
ProxyPass / balancer://mycluster/
ProxyPassReverse / balancer://mycluster/
</VirtualHost>
Both bits I used to talk to each other work fine. The first bit and the second bit.
Questions
I am a bit confused which bit should I use, the first bit or the second bit ?
Are any other bit(s) I can also try out for a bit of practice ?
