Running Apache Traffic Server on Fedora 13

Apache Traffic server from Yahoo! Inc. is really powerful, extensible web server which is proved to serve 75K reqs/sec on commodity hardware.

In this post, you'll learn how to download and run the Traffic server on your desktop, notebook.


1. Download TrafficServer 2.0.1 (latest as of 30-Sep-2010)

http://trafficserver.apache.org/downloads.html

2. Install the following packages



[nareshv@fallenangel ~]$ sudo yum install autoconf automake \
libtool gcc-c++ glibc-devel \
openssl-devel tcl-devel \
expat-devel sqlite-devel \
pcre-devel -y



3. Extract the trafficserver and build it



[nareshv@fallenangel ~]$ tar jxf trafficserver-2.0.1.tar.bz2
[nareshv@fallenangel ~]$ cd trafficserver-2.0.1
[nareshv@fallenangel trafficserver-2.0.1]$ ./configure
[nareshv@fallenangel trafficserver-2.0.1]$ gmake
[nareshv@fallenangel trafficserver-2.0.1]$ sudo gmake install



Now, all the required files would be installed in "/usr/local" instead of Fedora's default /usr. Lets configure Traffic server to act as ReverseProxy for apache

5. set servername of your proxy (so that it will come up in the HTTP headers)



[nareshv@fallenangel ~]$ sudo vim /usr/local/etc/trafficserver/records.config

# Change line 22 (it might vary) to put your hostname like shown below
22 #CONFIG proxy.config.proxy_name STRING <proxy_name>
22 CONFIG proxy.config.proxy_name STRING fallenangel




6. Make the Traffic server listen on port 80 by default



[nareshv@fallenangel ~]$ sudo vim /usr/local/etc/trafficserver/records.config

# Change 8080 port to 80 like shown below
105 #CONFIG proxy.config.http.server_port INT 8080
105 CONFIG proxy.config.http.server_port INT 80



7. Make Traffic server act as reverse proxy for apache

You can add as many rules as you want. The configuration file is well defined


[nareshv@fallenangel ~]$ sudo vim /usr/local/etc/trafficserver/remap.config

124
125 map http://localhost:80/ http://localhost:8080/
126 map http://fallenangel:80/ http://localhost:8080/




8. configure apache to listen on port 8080



[nareshv@fallenangel ~]$ sudo vim /etc/httpd/conf/httpd.conf
# Change it from default port 80 to 8080
#Listen 80
Listen 8080



9. Restart apache



[nareshv@fallenangel ~]$ sudo /etc/init.d/httpd restart



10. Restart traffic server



[nareshv@fallenangel ~]$ sudo /usr/local/bin/trafficserver restart
Stopping traffic_cop: [ OK ]
Stopping traffic_manager: [ OK ]
Stopping traffic_server: [ OK ]
Starting Apache Traffic Server: [ OK ]



11. Make simple request to your TrafficServer to test if everything is ok



[nareshv@fallenangel ~]$ ~]$ curl -v http://localhost/
* About to connect() to localhost port 80 (#0)
* Trying ::1... Connection refused
* Trying 127.0.0.1... connected
