Tomcat8 uses cronolog to perform log segmentation method

background

If the log files generated by tomcat are not processed in segmentation, they will often lead to larger and larger files, affecting efficiency. At the same time, if you need to find log files, it is also difficult to find in such a large log file. It is best to divide the log files by day. Here is a way to split the log file using cronolog

method

Install cronolog-1.6.

Download address:cronolog-1.6.

tar -zxvf cronolog-1.6.
cd cronolog-1.6.2
./configre # --prefix=/opt/cronolog , you can specify the installation directory, by default in /usr/local/sbin/cronologmake
make install

Tomcat configuration

Previous versions of Tomcat7:

vim tomcat/bin/
# Comment out (#)touch “$CATALINA_BASE”/logs/
# Modify two files in tomcat bin directory “$@” start \
>> “$CATALINA_BASE”/logs/ 2>&1 &
# for "$@" start 2>&1 \
| /usr/local/sbin/cronolog "$CATALINA_BASE"/logs/catalina.%Y-%m-% >> /dev/null &

After completing it, restart Tomcat and you can see the logs in the logs file with style .2015-09-13.

Versions after Tomcat7:

vi tomcat/bin/
#first stepWill
if [ -z "$CATALINA_OUT" ] ; then
CATALINA_OUT="$CATALINA_BASE"/logs/
fi
Modified to
if [ -z "$CATALINA_OUT" ] ; then
CATALINA_OUT="$CATALINA_BASE"/logs/catalina.%Y-%m-%
fi
# Step 2Will
touch "$CATALINA_OUT"
Change to
#touch "$CATALINA_OUT"
echi "$CATALINA_OUT"
# Step 3Will
 "$@" start \
>> "$CATALINA_OUT" 2>&1 &
Modified to
 "$@" start 2>&1 \
| /usr/local/sbin/cronolog "$CATALINA_OUT" >> /dev/null &

After completing it, restart Tomcat and you can see that the logs with style .2021-09-01 exists in the logs file.
