But when I try to manually start with >>>>>>> service squid start [root@proxysrv ~]# service squid start squid: unrecognized service I also want to configure it for autostart at startup of server. It give me following error [root@proxysrv ~]# chkconfig --add squid error reading information on service squid: No such file or directory [root@proxysrv ~]# Any body can help me to setup squid which is able to start/stop with service command & also configure for autostart using chkconfig --level 345 on.
