Internet object caching is \ # a way to store requested Internet objects (i.e., data available \ # via the HTTP, FTP, and gopher protocols) on a system closer to the \ # requesting site than to the source. Web browsers can then use the \ # local Squid cache as a proxy HTTP server, reducing access time as \ # well as bandwidth consumption. # pidfile: /var/run/squid-dev.pid # config: /etc/squid/squid-dev.conf PATH=/usr/bin:/sbin:/bin:/usr/sbin export PATH # Source function library. . /etc/rc.d/init.d/functions # Source networking configuration. . /etc/sysconfig/network # don't raise an error if the config file is incomplete # set defaults instead: SQUID_OPTS=${SQUID_OPTS:-"-D"} SQUID_PIDFILE_TIMEOUT=${SQUID_PIDFILE_TIMEOUT:-20} SQUID_SHUTDOWN_TIMEOUT=${SQUID_SHUTDOWN_TIMEOUT:-100} # determine the name of the squid binary [ -f /usr/sbin/squid ] && SQUID=squid prog="$SQUID-dev" # determine which one is the cache_swap directory CACHE_SWAP=`sed -e 's/#.*//g' /etc/squid/squid-dev.conf | \ grep cache_dir | awk '{ print $3 }'` [ -z "$CACHE_SWAP" ] && CACHE_SWAP=/var/spool/squid-dev RETVAL=0 start() { #check if the squid conf file is present if [ ! -f /etc/squid/squid-dev.conf ]; then echo "Configuration file /etc/squid/squid-dev.conf missing" 1>&2 exit 6 fi . /etc/sysconfig/squid-dev # don't raise an error if the config file is incomplete. # set defaults instead: SQUID_OPTS=${SQUID_OPTS:-"-D"} SQUID_PIDFILE_TIMEOUT=${SQUID_PIDFILE_TIMEOUT:-20} SQUID_SHUTDOWN_TIMEOUT=${SQUID_SHUTDOWN_TIMEOUT:-100} if [ -z "$SQUID" ]; then echo "Insufficient privilege" 1>&2 exit 4 fi for adir in $CACHE_SWAP; do if [ ! -d $adir/00 ]; then echo -n "init_cache_dir $adir...
