While there currently is no fix for the apache process running up to 100% CPU when used with Lasso 8.5.6 on CentOS 5.5 32bit or 64bit with in a VM, rarely ever on a stand alone server, and taking down the server, I have found a way to reduce the occurrence greatly. Under heavy load, the server may still ramp up, but, the apache process will still continue to respond and will release load as the load decreases. I custom compiled Apache 2.0.63 and the Lasso Connector for Apache2 for CentOS 5.5 64bit ONLY and packaged it up into a tar ball for easy installation. I have posted the tar ball here or follow the directions below. This assumes you already have Lasso 8.5.6 installed on CentOS 5.5. If you need help with that, I have a script for it too. You will either need to sudo most all of this or run as root.
# cd /usr/local/
# wget http://execuchoice.net/files/apache2.tgz
# tar xzfp apache2.tgz
# rm apache2.tgz

Now there are only a few changes needed to make the system use this custom build rather than the default install.
# mv /usr/sbin/apachectl /usr/sbin/apachectl.bak
# ln -s /usr/local/apache2/bin/apachectl /usr/sbin/apachectl
# cp -p /etc/init.d/httpd /etc/httpd.bak

Use your editor of choice –
# nano /etc/init.d/httpd
OR
# vi /etc/init.d/httpd

Look for this line:
httpd=${HTTPD-/usr/sbin/httpd}
Change to:
httpd=${HTTPD-/usr/local/apache2/bin/httpd}
and this:
CONFFILE=/etc/httpd/conf/httpd.conf
to:
CONFFILE=/usr/local/apache2/conf/httpd.conf
These changes will make the init (startup) script start apache2 from our custom build and use the appropriate config file. Once this is all done, you should just use the following to start up apache2 from our custom build.
# sudo apachectl start
To check and ensure that you are using the correct version you can simply execute the following to verify:
# ps w -C httpd
You should see something to the effect of
8889 ? S 0:00 /usr/local/apache2/bin/httpd -k start
There you have it.

Special thanks to Brian Loomis who contracted me to do this and gracefully permitted me to provide this to the public free of charge.

Be sure to let me know how it works for you. Hopefully we won’t have to rely on this for too much longer since Lasso 8.6 is now in beta testing.

I had a client who wanted AFP services to work on CentOS 5.5 since he was moving from MacOS X. I was saddened to see that it was not already in the CentOS, EPEL or Remi’s repos. So, I set out on a journey to get it included in the Remi or EPEL repos. I contacted Jiri Skala, the Fedora package maintainer, to get it moved into EPEL 5 & 6. You can see the requests here and here. Unfortunately the latest version that could be installed is 2.0.x via EPEL. That did not do it for me so I took the time to research how to build it for CentOS 5 and make it all work.

I downloaded the Webmin module .9b4 and tried to use it but it is lacking of a semi-finished product. I spent the better portion of a day going through and fixing up the code. I emailed it to the package maintainer directly because I do not yet use GIT or DIFF to send him the differences. I’ve posted it here for anyone to test and build on. If you do revise it, send it to me so I can add it to what I have and I’ll keep track of the changes until the original author has time to post it.

I tried to follow instructions on this page but found them slightly off. Here is what worked for me.

# yum install openssl.x86_64 libssl-dev gcc automake autoconf GSSAPI libgssapi-devel libgssapi libgssapi-devel krb5-devel pam-devel shadow-devel openssl-devel cracklib wget
# mkdir /downloads
# cd /downloads

Now to begin downloading and manually building the packages. The following will build the berkeley db binaries, libs etc into /usr/local by default. I recommend not changing this since it just works.

# wget http://download.oracle.com/berkeley-db/db-4.8.30.tar.gz
# tar xzfp db-4.8.30.tar.gz
# cd db-4.8.30/build_unix/
# ../dist/configure
# make
# make install

Now to begin building the netatalk package.

# wget "http://downloads.sourceforge.net/project/netatalk/netatalk/2.1.5/netatalk-2.1.5.tar.bz2?r=http%3A%2F%2Fsourceforge.net%2Fprojects%2Fnetatalk%2F&ts=1293643408&use_mirror=biznetnetworks"
# tar xjfp netatalk-2.1.5.tar.bz2
# cd netatalk-2.1.5
# ./configure --prefix=/usr --sysconfdir=/etc --enable-redhat --enable-pgp-uam --enable-krb4-uam --enable-krbV-uam --with-bdb=/usr/local/BerkeleyDB.4.8/
# make
# make install

When I did the make install, it created the directories for me and copied all the config files over except afp_ldap.conf. I copied that one manually.

# cp config/afp_ldap.conf /etc/netatalk/

From there all you have to do is either manually start the services or use the Webmin module to do it.

# chkconfig netatalk on
# service netatalk start

After that its only a matter of going in and configuring things. The webmin module does only a basic job but will save some time. Custom tweaks can be done by the Edit Config Files link I added rather than having to use the terminal to do it.

I decided to create this post to provide some of my open source projects to the public. I’ll post messages with links to source as time provides.
