Installation von squid

Wir brauchen eine angepasste Version von squid
Diese können wir selbst komplilieren oder das squid-openssl Paket von nutzen
  • apt install squid-openssl

Erstellen eines Selbstsignierten Zertifikates

Variablen setzen und Verzeichnis anlegen
  • CERT_D=/etc/squid/certs/
  • CERT=$CERT_D/squid_proxyCA.pem
  • rm -rf $CERT
  • mkdir -p $CERT_D
Generieren Sie ein lokales selbstsigniertes CA-Zertifikat und geheimen Schlüssel (in derselben Datei))
  • openssl req -new -newkey rsa:4096 -sha256 -days 365 -nodes -x509 -keyout $CERT -out $CERT
  • chown -R proxy:proxy $CERT_D
  • chmod 0400 $CERT
füge das squid_proxyCA-Zertifikat zum System hinzu, damit es standardmäßig vertrauenswürdig ist
  • CA_CERT_D=/usr/local/share/ca-certificates
  • rm -rf $CA_CERT_D/*
  • mkdir -p $CA_CERT_D
  • openssl x509 -inform PEM -in $CERT -out $CA_CERT_D/squid_proxyCA.crt
  • update-ca-certificates
