Hello,
I have a certain task that I'd like to do but not sure what the best
way to do it with cfengine. Any advice appreciated.
Let's say I want have a file /etc/httpd/conf.d/log_sql.conf that looks
like the following on a couple of servers:
LoadModule log_sql_module modules/mod_log_sql.so
LoadModule log_sql_mysql_module modules/mod_log_sql_mysql.so
LogSQLLoginInfo mysql://my:[EMAIL PROTECTED]/apachelogs
LogSQLCreateTables on
LogSQLMassVirtualHosting On
LogSQLTransferLogFormat AabHhMmRrSsTUuv
LogSQLMachineID $(short_hostname)
Now short_hostname should be replaced with a variable that I define:
short_hostname = ( ExecResult(/bin/hostname -s) )
So basically I have almost identical data in the file except for the
last line, which is specific to each host. Right now I'm using an
editfiles like the following:
editfiles:
{ /etc/httpd/conf.d/log_sql.conf
Backup "off"
AutoCreate
DefineClasses "httpd_restart"
BeginGroupIfNoLineMatching ".*LogSQLLoginInfo.*"
Append "LoadModule log_sql_module
modules/mod_log_sql.so"
Append "LoadModule log_sql_mysql_module
modules/mod_log_sql_mysql.so"
Append "LogSQLLoginInfo
mysql://my:[EMAIL PROTECTED]/apachelogs"
Append "LogSQLCreateTables on"
Append "LogSQLMassVirtualHosting On"
Append "LogSQLTransferLogFormat AabHhMmRrSsTUuv"
Append "LogSQLMachineID $(short_hostname)"
EndGroup
}
But the problem is this does not really enforce the file always being
the same. I want to distribute it from cfengine if those first 6 lines
ever change. If the file isn't there I'd like it to be created and
httpd restarted. I don't think I could do a copy: because the checksum
will always be different with the short_hostname variable. If I do
that and then an editfiles: afterwards, it seems I would always be
restarting httpd.
Thanks,
viraj.
