hi all, atm i have written a script, once you have built a centos 7 VM, you just run the script and after the reboot its a complete running squidclamAV server
i'm going to be moving the script to a ubuntu server as centos 7 is dead now (as i run clamAV on it, clamAV will stop getting virus definitions 2024 as i use this for virus scanning of internet packets) just want to know what lines i need to adjust to work with ubuntu instead of centos, obviously i know instead of yum install.... its apt install heres my long script #!/bin/bash # #this script will download/install and configure the following packages # #squid - proxy server #squid ssl bump - intercept HTTPS traffic #clamAV - antivirus engine inc trojans,viruses,malware #c-icap - icap server #squidclamav - that integrates all the above in squid #whitelist URL's #deny MIME types # #on the PROD host you only need squid # #first things first lets disable firewalld and SElinux # systemctl stop firewalld systemctl disable firewalld sed -i -e 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config #
