For 2023 - we are now fully retired from IT training. We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.
Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!
I am also active in many other area and still look after a lot of web sites - you can find an index ((here)) |
Stopping and restarting Apache httpd cleanly
If you'r running an Apache httpd server and you need to restart it, then you may be used to running:
apachectl stop
apachectl start
and in close succession, those should cause only a minor blip in service of perhaps a second or two; the sort of thing that can be put down to a "sticky internet". But you can do better
apachectl restart
Runs a configuration test before it stops the old daemon so that if you've editied your configuration file and introduced a fatal error, it won't go ahead with the stop. It also means that the restart is at electronic speed after the stop, curtting the blip. But you can do better
apachectl graceful
Runs the configuration test, AND allows currently open connections to be concluded before rebooting - thus ensuring that no-one gets a partial page as you cycle your httpd.
Note - if you have allowed per-directory changes to the configuration via .htaccess files, then you don't need to restart the server in any way when they're changed - they are checked at every web site "hit". (written 2006-03-29, updated 2006-06-05)
