Most people do not understand the knowledge points of this article "how to configure and install Squid3.0 reverse proxy under centos", so the editor summarizes the following contents, detailed contents, clear steps, and has a certain reference value. I hope you can get something after reading this article. Let's take a look at this "how to configure and install Squid3.0 reverse proxy under centos" article.

Installation:

The application environment of this tutorial is clean centos 5.5. pre-partition and load / data partition, and close selinux and iptables

First modify the file descriptor and set the temporary port range, which will take effect after restart

The copy code is as follows:

Cat > > / etc/security/limits.conf / etc/sysctl.conf / etc/rc.local

Maintenance section:

Here are the commands commonly used by squid

If the configuration file has been modified, reread the configuration file with the following command (effective immediately)

/ usr/local/squid3/sbin/squid-k reconfigure

Check that the syntax of the configuration file is correct

Note: only "cache_cf.cc (346) squid.conf:14 unrecognized: 'http1_port'" like this is a syntax error.

"warning: use of 'reload-into-ims'." Such tips belong to opinions and suggestions and can be ignored.

/ usr/local/squid3/sbin/squid-k parse

Check the log and process of squid to see if squid is running properly.

Ps-ef | awk'/ ^ squid/'

Cat / data/squidlog/cache.log

/ usr/local/squid3/sbin/squid-k check; echo $?

Close squid

Send a shutdown signal and close completely when the session is over

/ usr/local/squid3/sbin/squid-k shutdown

Turn off squid (higher priority, turn off squid directly)

/ usr/local/squid3/sbin/squid-k interrupt

Turn off squid (highest priority, directly kill the squid process)

/ usr/local/squid3/sbin/squid-k kill

Scroll log file

/ usr/local/squid3/sbin/squid-k rotate

Set the log to scroll automatically at 04:30 every Tuesday morning

Echo "30 4 * * 2 root / usr/local/squid3/sbin/squid-k rotate" > > / etc/crontab

At present, the squid.conf files in the application are directly exported to / dev/null and discarded because the log files are growing rapidly.

The copy code is as follows:
