New page

If you are using mod_cache/mod_disk_cache to use disk cache on Apache/IBM HTTP Server, you must run htcacheclean to cleanup cache to not be out of space.

htcacheclen takes too much time to run. So i create a script that run htcacheclean against sub-directories, this way the command run faster.

'''Procedure'''

'''1)''' Create a file cleancache.sh, and put the following content:

#!/bin/bash
APACHE_BIN_DIR=/opt/IBM/HTTPServer/bin
LOGFILE=/var/log/httpd/cleancache.log
CACHE_FILES=var/cache/mod_disk_cache

# Cache Size in GB
SIZE=2;

echo "############################################" > $LOGFILE
NOW=$(date +"%Y-%m-%d-%H-%M-%S")
echo "[$NOW] Start Cleanup Cache" >> $LOGFILE
echo "" >> $LOGFILE
echo "############################################" >> $LOGFILE
df -g >> $LOGFILE
echo "############################################" >> $LOGFILE
df >> $LOGFILE
echo "############################################" >> $LOGFILE

# We must divide SIZE by the number of directories (4096),
# to get the per-directory limit, in megabytes
LIMIT=$(( $SIZE * 1024 * 1024 / 4096 ))K;

for i in $CACHE_FILES/*;
do
NOW=$(date +"%Y-%m-%d-%H-%M-%S")
echo "[$NOW] Diretorio $i" >> $LOGFILE
#du -sm $i >> $LOGFILE
$APACHE_BIN_DIR/htcacheclean -v -t -p$i -l$LIMIT >> $LOGFILE 2>&1
#du -sm $i >> $LOGFILE
echo "" >> $LOGFILE
done;

echo "" >> $LOGFILE
echo "############################################" >> $LOGFILE
df -g >> $LOGFILE
echo "############################################" >> $LOGFILE
df >> $LOGFILE
echo "############################################" >> $LOGFILE
NOW=$(date +"%Y-%m-%d-%H-%M-%S")
echo "[$NOW] End of Cleanup Cache" >> $LOGFILE

Save and close

2) Change permission

chmod a+x cleancache.sh

3) Putting on Cron:

Edit crontab using crontab -e

Add the following lines

###### Script de Limpeza do Cache do IBM HTTP Server######
0 4 * * 6 /opt/IBM/HTTPServer/bin/cleancache.sh
