New Networking
Apache 1.3.14 for MPE/iX
so it resides in /APACHE/A0200. The next Apache for MPE/iX release will reside in
/APACHE/A0300. The files in a version specific group should not to be customized such
as the utitlities in bin/, man pages in man/, and manual pages in htdocs/manual. These
files are accessed via a symbolic links from PUB.APACHE.
• The installation script creates a symbolic link named CURRENT that points to the
active version-specific group:
shell/iX> ll /APACHE
total 7
drwxrwxr-x 14 MGR.APACHE APACHE 600 Apr 6 11:54 A0200
lrwxrwxrwx 1 MGR.APACHE APACHE 5 Apr 6 11:55 CURRENT -> A0200
drwxrwxr-x 13 MGR.APACHE APACHE 1000 Apr 6 11:55 PUB
• The installation also creates symbolic links below the PUB group that point indirectly
into the version-specific group via the CURRENT symbolic link. Any existing symbolic
links are updated with new links and existing files and directories are saved to a
backup copy. For example, the /APACHE/PUB/bin directory will be saved to bin.bak and
then linked to the new version’s bin directory. In this way, a reference to
/APACHE/PUB/bin/htpasswd accesses /APACHE/A0200/bin/htpasswd
/APACHE/PUB/bin -> /APACHE/CURRENT/bin
• The installation does not purge the previous version-specific group. When satisfied
with a new version, the user can execute :PURGEGROUP on the previous
version-specific group to remove it from the machine.
:PURGEGROUP /APACHE/A0200
• To backdate to files in PUB.APACHE, the user would purge a file's symlink then restore
its previous version from the .bak file.
shell/iX> cd /APACHE/PUB
shell/iX> rm HTTPD
shell/iX> mv HTTPD.bak HTTPD
Here is what PUB.APACHE looks like after an installation:
shell/iX> ll /APACHE/PUB
