[root@deep /]# useradd -d /cache/ -r -s /dev/null squid >/dev/null 2>&1 [root@deep /]# mkdir /cache/ [root@deep /]# chown -R squid.squid /cache/ First of all, we add the user “squid” to the “/etc/passwd” file, then we create the “/cache” directory if this directory doesn’t exist and only if it doesn’t exist. Finally we change the owner of the directory “cache” to be the user “squid”. NOTE: Usually we don’t need to make the command (mkdir /cache/) because we have already created this directory when we have partitioning our hard drive during the installation of Linux. If this partition doesn’t exist then you must execute this command to create the directory. Step 2 Move into the new Squid directory and type the following commands on your terminal: Edit the Makefile.in file (vi +18 icons/Makefile.in) and change the line: DEFAULT_ICON_DIR  =  $(sysconfdir)/icons To read: DEFAULT_ICON_DIR  =  $(libexecdir)/icons We change the variable (sysconfdir) to be (libexecdir). With this modification, the “icons” directory of Squid will be located under the “/usr/lib/squid” directory. Edit the Makefile.in file (vi +34 src/Makefile.in) and change the lines: DEFAULT_CACHE_LOG  =  $(localstatedir)/logs/cache.log To read: DEFAULT_CACHE_LOG  =  $(localstatedir)/log/squid/cache.log DEFAULT_ACCESS_LOG  =  $(localstatedir)/logs/access.log To read: DEFAULT_ACCESS_LOG  =  $(localstatedir)/log/squid/access.log DEFAULT_STORE_LOG  =  $(localstatedir)/logs/store.log To read: DEFAULT_STORE_LOG  =  $(localstatedir)/log/squid/store.log DEFAULT_PID_FILE  =  $(localstatedir)/logs/squid.pid To read: DEFAULT_PID_FILE  =  $(localstatedir)/run/squid.pid DEFAULT_SWAP_DIR  =  $(localstatedir)/cache To read: DEFAULT_SWAP_DIR  =  /cache DEFAULT_ICON_DIR  =  $(sysconfdir)/icons To read: DEFAULT_ICON_DIR  =  $(libexecdir)/icons
