A common classic application is to split a single huge log of Apache and save and install it by date: -------------- -------------------------------------------------- ------------

$ tar xvzf cronolog-1.6.2.tar.gz
$ cd cronolog-1.6.2
$ ./configure --prefix=/usr/local
$ make
$ sudo make install

-------------------------------------------------- --------------------------- Check where it is installed (which also requires sudo permission): which cronolog Simple test $ echo "This is a test." |/usr/bin/cronolog -o/var/log/www/%Y/access.%m-%d-%y.log "-o" command can be used to create a file without adding an error ok! Write a script file cam-hello with no extension for the self-starting program for your own web server: ------------------------------- ----------------------------------------------

# place the daemon scripts in a folder accessible by root./usr/local/sbin is a good idea

-------------------------------------------------- --------------------------- --make-pidfile can create a self-starting file, which is misled by the imperfect program on the Internet, which can only start but not Stop service ==! The python script needs to be changed to an executable file, otherwise the log file cannot be run. The log file has a buffer and can be written to a certain length. It is very speechless (I thought that python can't do this in the experiment...) Deploy the self-starting program and copy it to/etc/rc .d/init.d/Modify the script file chmod 777 cam-hello Register:/etc/init.d# sudo update-rc.d cam defaults If you want to delete the start/stop links, then: sudo update-rc.d -f cam remove (Note: chkconfig --add autoruntest add service command is wrong, don’t use it! There is a loop between service apache2 and rsyslog if stopped) After the deployment is successful

/etc/init.d/cam-hello start
/etc/init.d/cam-hello restart
/etc/init.d/cam-hello stop
