Upgrade Apache from 2.0.53 to 2.2.6

On solaris, I have *always* built apache from source.   It's easy, and you end up getting everything you need.   For example, a commonly-used binary, "apxs", is often NOT included in pre-built packages, and this can make trying to add various modules later a huge pain.    In addition, with a package, you have no control where the binaries and config files go.    Totally controllable with a source build--   in fact, with a source build, you can build the new apache to go SOMEWHERE ELSE---  and end up with BOTH the old and new apache setups on the same box for testing (note: make sure both don't listen to tcp port 80- at the same time!).

As far as the steps:

in the (new) apache directory--    

./configure
make
make install

BUT-- there are options, and I'm not sure how coldfusion fits into there--  for that, take a CLOSE look at the existing httpd.conf.  

What is the best way to make sure that you are building the new version with the same conf as the current one that;s running?  

.  

If the old one was built from source, look for "config.log" in the source directory- that will tell you exactly how it was configure (./configure --option1 --option2 ... etc).

The top of the config log will look like this:

It was created by configure, which was
generated by GNU Autoconf 2.59.  Invocation command line was

  $ ./configure --enable-module=so --enable-rewrite





Otherwise, if your apache was not built from source on your host,  check out the output of /path/to/apache/httpd -V  (i.e., /usr/local/apache/bin/httpd -V) - it will tell you what options apache was compiled with (note, many of them are probably defaults).

It will look like this:

Server version: Apache/2.2.3
Server built:   Nov 20 2007 09:20:13
Server's Module Magic Number: 20051115:3

 -D DEFAULT_ERRORLOG="logs/error_log"
 -D AP_TYPES_CONFIG_FILE="conf/mime.types"
 -D SERVER_CONFIG_FILE="conf/httpd.conf"

Is there a way to run ./configure to look at the current apache that is installed and build it based on that?

If not, this is what I was going to do to upgrade.  

Make a backup of the existing apache 2 folder that is currently installed.  
Install the new apache 2.2.4 package
replace the httpd.conf
restart apache.  

Is there any other files or folders that I need to mv from the old apache2 backup?  

Thanks
     

No, configure will not automatically know what to do, nor does the configure script have a way to tell "how" your existing apache was built.      You need to tell it.    My previous posting described how you have to figure out your current apache was built from: either find the config.log, or see above for running httpd and displaying the apache options used at compile-time.

If you are planning on upgrading apache in the same directory as it is now (sounds like that's your plan)- then no, you shouldn't have to copy or move anything - even the httpd.conf file you have now WILL BE PRESERVED.

The simplest thing to do:

STOP apache.

create a backup of the entire existing apache tree.  
cd /some/directory
tar cvf apache-backup.tar /usr/local/apache2   (assuming that's where apache is now)


Build new apache, install it into the same directory
./configure --options-you-need-once-you-find-them-if-there-are-any
make
make install

Test.

Voila!    With the backup, you can safely do the above.    If you have problems, restore the backup and go from there.

Here is what I get from httpd -V

[************] /usr/local/apache2/bin > ./httpd -V

What options where used?  

I think this is the pkg that they used.
