The following lists the initial steps involved in getting a generic Traffic Server install up and running.

NOTE:  Please use the following with Apache Traffic Server v5.0.0 and higher.

IP Address Listening And Ports

Unlike Apache HTTP Server, Traffic Server takes a little more work to get things up and running.
The following settings are all located in the main configuration file, which by default is
/usr/local/etc/trafficserver/records.config.

...

I was originally using localhost, but after looking at the HTTP proxy headers that ATS produced, I decided to be more specific.

Required Remapping

The Apache Traffic Server default install configures URL re-mapping as required.

...

CONFIG proxy.config.url_remap.remap_required INT 0

IP

...

-based Access Control List

To setup basic security in your Traffic Server install, you'll have to configure a different file,
by  by default /usr/local/etc/trafficserver/ip_allow.config.

If you've ever done firewall
work firewall work the theory is very similar...simply list to Traffic Server what is allowed,
followed  followed by what is NOT allowed.

# Allow anything on localhost (this is the default configuration based on the
# depricated CONFIG proxy.config.http.quick_filter.mask INT 0x482)
src_ip=2601:d:4880:536c3:426c:8fff:fe3a:43f1         action=ip_allow method=ALL
# Deny everything else.
src_ip=0.0.0.0-255.255.255.255                    action=ip_deny  method=ALL
src_ip=::-ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff action=ip_deny  method=ALL

Web Cache Size

The Apache Traffic Server default install configures this to be 256MB, a rather small size
as size as is noted in the configuration file.

I eventually went with 8GB. The following is found in the
config the config file /usr/local/etc/trafficserver/storage.config.

var/trafficserver 8G

Web Cache Partitions

The Apache Traffic Server default install doesn't really provide for this. I found over time this can cause all sorts of issues relating to disk lock contention.

The following is found in the config file /usr/local/etc/trafficserver/volume.config.

volume=1 scheme=http size=25%
volume=2 scheme=http size=25%
volume=3 scheme=http size=25%
volume=4 scheme=http size=25%

Start It Up!

Once the above has been completed, it's time to give it all a try.

...

At this point you should have a workable, albeit very default web caching proxy server.

Startup your favorite browser, configure it to use your new proxy server as a web proxy
for proxy for both HTTP and HTTPS, and watch your browsing speed improve immediately.
