  1. Setup / Tune Proxy Server Squid for RTC Wayne Chiang 04/24/2013

  2. What is squid • Popular open source proxy server. • Caching proxy for the Web supporting HTTP, HTTPS, FTP, and more. • Reduces bandwidth and improves response times by caching and reusing frequently-requested web pages.

  3. Download and Build • http://www.squid-cache.org/Versions/ • Latest release 3.3.3 (released 3/12/2013) • I have built it on miles-lab (Linux 6.4) /home/mlsinst/squid/squid-3.3.3 • Installed on /home/mlsinst/squid/install333 • Proxy of https://satchmo.ottawa.ibm.com:9443 to https://miles-lab.ottawa.ibm.com:9843

  5. Run squid • Cd /home/mlsinst/squid/install333/sbin • Run './squid -z' to create the directory structure for the first time. • Run './squid' to start the proxy on Linux. • To stop the proxy, you can run "./squid -k shutdown". 

  6. access.log • TCP_HIT • A valid copy of the requested object was in the cache. • TCP_MISS • The requested object was not in the cache. • TCP_MEM_HIT • A valid copy of the requested object was in the cache and it was in memory, thus avoiding disk accesses.

  7. Tuning Squid • Set the "cache_mem" directive in squid.conf as large as possible • Set the "cache_dir" directive in squid.conf to a large value will increase the disk-based cache size for squid. • Turn off access logging if you do not require it for day to day use

  8. Reference • Setting up the Squid Caching Proxy w/SSL for RTC 2.0 • Using content caching proxies for Jazz Source Control

  9. Q&A
