SYNOPSIS
use esmith::Build::CreateLinks qw(:all);
safe_symlink("../../../functions/$function", "$cgibin/$function")
the beginning is always the same
#!/usr/bin/perl -w use esmith::Build::CreateLinks qw(:all);
DESCRIPTION
safe_symlink
This function works like symlink(), but if the directory being linked to does not exist, it will create it.
ie. safe_symlink("../../../functions/$function", "$cgibin/$function")
- links to add
safe_symlink("/etc/e-smith/templates-default/template-begin-php", "root/etc/e-smith/templates/etc/test/db.php/template-begin");
safe_symlink("/etc/e-smith/templates-default/template-end-php", "root/etc/e-smith/templates/etc/test/db.php/template-end");
- service to restart on demand
for my $event (qw(
conf-roundcube
))
{
templates2events("/etc/httpd/conf/httpd.conf", $event); #####expand-template on event conf-roundcube
safe_symlink("restart", "root/etc/e-smith/events/$event/services2adjust/mysql.init"); #####restart mysqlinit on event conf-roundcube
safe_symlink("sigusr1", "root/etc/e-smith/events/$event/services2adjust/httpd-e-smith"); #####restart httpd on event conf-roundcube
}
panel_link
This function creates a link to a web panel.
ie.
my $panel = "manager";
panel_link("tug", $panel);
admin_common_link
This function creates a symlink from the common manager directory to a file in the functions directory.
event_link
This function creates a symlink from an action’s ordered location in an event directory to its action script.
ie.
my $event = "tug-update";
event_link("tug-conf", $event, "10");
event_link("conf-masq", $event, "20");
event_link("adjust-masq", $event, "30");
event_link("tug-restart", $event, "40");
service_link_enhanced
This function creates a symlink from a SysV init start or kill link in a runlevel to e-smith-service, a wrapper that is config db aware.
ie.
safe_symlink("daemontools", "root/etc/rc.d/init.d/tug");
service_link_enhanced("tug", "S85", "7");
service_link_enhanced("tug", "K25", "6");
service_link_enhanced("tug", "K25", "0");
safe_symlink("/var/service/tug/", "root/service/tug");
of course the job script needs to be in /var/service/tug (should be relevant that it needs to be named by the same name : tug)
safe_touch
This function creates an empty file, but first creates any enclosing directories. For example:
safe_touch("a/b/c/d");
will create any of the directories "a", "a/b", "a/b/c" which don’t exist, then create an empty file "a/b/c/d".
templates2events
This function creates a file tree (of empty files) which is used by the generic_template_expand action to determine which templates need to be expanded for a particular event. Takes one file argument and a list of event names, e.g.
templates2events("/etc/some/file", "event1", "event2", ...);
eg :
foreach my $event (qw(share-create share-modify share-delete share-modify-servers)){
templates2events("/etc/samba/smb.conf", $event);
templates2events("/etc/httpd/conf/httpd.conf", $event);
templates2events("/etc/rsyncd.conf", $event);
templates2events("/etc/proftpd.conf", $event);
}
could be written like that also
templates2events("/etc/e-smith/sql/init/phplistdb", qw/webapps-update bootstrap-console-save/);
templates2events("/etc/phplist/config.php", qw/webapps-update bootstrap-console-save/);
or more simply
templates2events("/opt/roundcube/config/db.inc.php", console-save);
