Come installare il server proxy SQUID

Il modo più rapido per usare un server proxy è con Docker:

docker run --name squid -p 3128:3128 --rm -d \
  -e PROXYLOGIN=mylogin \
  -e PROXYPASSWORD=mypassword \
  anticaptcha/squid

Se vuoi impostare il tuo file di configurazione, dove andrai ad impostare l'autenticazione, allora montalo su /etc/squid/squid.conf

docker run --name squid -p 3128:3128 --rm -d \
 -v /path/to/squid.conf:/etc/squid/squid.conf \
anticaptcha/squid

Un'altra opzione è quella di creare dalla sorgente:

yum -y install make gcc gcc-c++ libtool wget httpd-tools
wget http://www.squid-cache.org/Versions/v3/3.2/squid-3.2.3.tar.gz
tar -zxf squid-3.2.3.tar.gz
cd squid-3.2.3
./configure
make
make install

Esempio di file di configurazione:

#configure the port number
http_port 9191

cache_mem 5 MB
cache_dir ufs /usr/local/squid/var/cache 300 16 256
cache_access_log /usr/local/squid/var/logs/access.log
cache_log /usr/local/squid/var/logs/cache.log
cache_store_log /usr/local/squid/var/logs/store.log
pid_filename /usr/local/squid/var/logs/squid.pid

SQUID conserva i logins e le password in un file separato, nel nostro caso è "/usr/local/squid/etc/squid_users". Per gestire questo file, usa lo strumento "htpasswd":

htpasswd -c /usr/local/squid/etc/squid_users mylogin

Dopo aver terminato la configurazione, cambia i permessi delle directory di SQUID e usalo come demone:

chown -R nobody:nobody /usr/local/squid/share /usr/local/squid/var
/usr/local/squid/sbin/squid -z /usr/local/squid/etc/squid.conf
/usr/local/squid/sbin/squid -f /usr/local/squid/etc/squid.conf

Verifica che il proxy funzioni e che accetti le connessioni:

netstat -lenp|grep squid

curl -x IP_HERE:3128 -U mylogin:mypassword http://antigate.com/iptest.php
