The best and easy way to install squidGuard is via YUM repo .Here how to do it .

1.With Squid working you can now go about installing SquidGuard.

You will need to install additional repositories in CentOS, in order to access to necessary software packages that are not available in the default repositories. Install the Extra Packages for Enterprise Linux (EPEL), the epel-release for the current version of Enterprise Linux (EL6). You can find it at the following website: http://fedoraproject.org/wiki/EPEL. A direct link to the RPM is in the command below. Eventually the link will be outdated and need to be replaced. For 64 bit systems you can change /i386/ to /x86_64/ in the command below.
# yum install http://ftp.osuosl.org/pub/fedora-epel/6/i386/epel-release-6-8.noarch.rpm

=========================================================================

[root@aueq-sproxy02 ~]# yum install http://ftp.osuosl.org/pub/fedora-epel/6/i386/epel-release-6-8.noarch.rpm

2. cd /var/squidGuard/

tar -zxvf blacklists.tar.gz

mkdir db

mkdir log

chown -R squid:squid db
chown -R squid:squid log

mv blacklists/* db/

chown -R squid:squid db/*

3. Now edit the squidGuard.conf file to configure it to work with the testdomains file. You may want to back up the squidGuard.conf file before making changes.

 

[root@aueq-sproxy02 db]# cp /etc/squid/squidGuard.conf /etc/squid/squidGuard.conf.BAK

 

# vi /etc/squid/squidGuard.conf —> and change as following.

 

=============================================================

# Mohammad Alam 23/09/2016
# initial conf file for squidGuard

logdir /var/squidGuard/log
dbhome /var/squidGuard/db

dest whitelist {
domainlist whitelist/domains
urllist whitelist/urls
}

dest specBlacklist {
domainlist specBlacklist/domains
urllist specBlacklist/urls
}

dest ads {
domainlist ads/domains
urllist ads/urls
}

dest adult {
domainlist adult/domains
urllist adult/urls
}

dest aggressive {
domainlist aggressive/domains
urllist aggressive/urls
}

acl {
default {
pass whitelist !specBlacklist !ads !adult !aggressive !audio-video !drugs !porn !chat !warez !phishing !malware !in-addr all
redirect http://10.80.0.37/ERR_ACCESS_DENIED.html
}
}

 

==================================================================

 

4. Add this line to /etc/squid/squid.conf

url_rewrite_program /usr/bin/squidGuard -c /etc/squid/squidGuard.conf

5. Reload squidGuard db

squidGuard -b -d -C all

6. Restart Squid.

/etc/init.d/squid reload

7. Check the log file at /var/squidGuard/log

[root@aueq-sproxy02 log]# ls
squidGuard.log
[root@aueq-sproxy02 log]# tail -f squidGuard.log
2016-09-26 11:11:51 [2388] squidGuard 1.4 started (1474852311.153)
