Shen xiaoran Date:

./Configure
Make; make install

Default installation location:

Configure Tomcat log Segmentation

Edit the Catalina. Sh file in the bin directory of Tomcat

# Vi bin/Catalina. Sh

Find the following line

Org. Apache. Catalina. startup. Bootstrap "[email protected]" Start \
> "$ Catalina_out" 2> & 1 &

There are two rows like this. The first is Tomcat startup with the "-Security" parameter, and the second is the default Tomcat startup mode, that is, the part below Else, we only need to modify it here.

In addition, you need to comment out the "$ catalina_out" line of touch.

The complete modification is as follows:

# Touch "$ catalina_out"
If ["$1" = "-Security"]; then
If [$ have_tty-EQ 1]; then
Echo "using security manager"
Fi
Shift
"$ _ Runjava" "$ logging_config" $ logging_manager $ java_opts $ catalina_opts \
-Djava. endorsed. dirs = "$ java_endorsed_dirs"-classpath "$ classpath "\
-Djava. Security. Manager \
-Djava. Security. Policy = "$ catalina_base"/CONF/Catalina. Policy \
-Dcatalina. base = "$ catalina_base "\
-Dcatalina. Home = "$ catalina_home "\
-Djava. Io. tmpdir = "$ catalina_tmpdir "\
Org. Apache. Catalina. startup. Bootstrap "[email protected]" Start \
> "$ Catalina_out" 2> & 1 &

Else
"$ _ Runjava" "$ logging_config" $ logging_manager $ java_opts $ catalina_opts \
-Djava. endorsed. dirs = "$ java_endorsed_dirs"-classpath "$ classpath "\
-Dcatalina. base = "$ catalina_base "\
-Dcatalina. Home = "$ catalina_home "\
-Djava. Io. tmpdir = "$ catalina_tmpdir "\
Org. apache. catalina. startup. bootstrap "[email protected]" Start 2> & 1 |/usr/local/sbin/cronolog/usr/local/tomcat/logs/Catalina. % Y % m % d. out>/dev/null &
#>> "$ Catalina_out" 2> & 1 &

Fi

Save and exit
