SQUID3 cache server compile installation and high hit rate configuration sample _ Server Other

Today, my varnish carried out a small pressure test, 40s 8000 concurrency, no failure, an estimate can withstand a greater concurrency, not to mention varnish, I recently found a high percentage of squid profile, of course, squid3.0 configuration file, There is a need to copy back to their own change.

System: CentOS 5.x
Required Software: squid-3.0.stable25.tar.gz

3. Configure Squid

Copy Code code as follows:

Cp/usr/local/squid/etc/squid.conf/usr/local/squid/etc/squid.conf.old
>/usr/local/squid/etc/squid.conf
Ln-s/usr/local/squid/etc/squid.conf/etc/squid.conf

4. Create a table of contents

Copy Code code as follows:

/usr/sbin/groupadd Squid
/usr/sbin/useradd-g Squid Squid
Mkdir-p/var/log/squid
Chown-r Squid:squid/var/log/squid
Mkdir-p/var/{cache1,cache2}
Chown-r Squid:squid/var/{cache1,cache2}

Cache Directory of initialized squid

Copy Code code as follows:

/usr/local/squid/sbin/squid-z

Start squid

Copy Code code as follows:

/usr/local/squid/sbin/squid-d

If you do not like this way, you can find a squid to start the script, here is not released. When squid runs, you can use the following command to view the hit rate:

Copy Code code as follows:

/usr/local/squid/bin/squidclient-p Mgr:info

Well, the specific use of other SQUID commands can only you go to search, it is here.
