Using the CentOS 6 instruction for RHEL 6

Hi,

Here are my notes from installing 2 servers now as ispconfig lamp servers on Red Hat Enterprise Linux 6 64 bit. You may not like some of my methods, such as using the older RH subscription method, but it works. It is also the only way to get the additional software channels unless you install xwindows, but I didn't cuz gui's are evil!

I hope this helps someone:


Start with http://www.howtoforge.com/perfect-server-centos-6.2-x86_64-with-apache2-ispconfig-3 (TY Falko! and I mean it!)

Page 2
when selecting customize now or customize later, select customize now, and add emacs to the packages. (I added this step to start an emacs vs vi holy war )

Page 3 installing EPEL
ver. 6.5 is not available. use the line
"wget http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm"
instead of
"wget http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-5.noarch.rpm"

Page 3 section 7 when importing additional repositories do the line:
"rpm --import http://apt.sw.be/RPM-GPG-KEY.dag.txt"
instead of
"rpm --import http://dag.wieers.com/rpm/packages/RPM-GPG-KEY.dag.txt"
since the import file has moved

Page 3 before installing yum_priorities you have to subscribe your server with RHN and enable an additional software channel
rhn_register to register as RHN Classic on the command line
go to https://access.redhat.com/home
sign in
Subscriptions>Your Subscriptions> Overview
RHN Classic
click server name
click software tab
click Software Channels
click the box next to: RHEL Server Optional (v. 6 64-bit x86_64)
scroll to bottom and click the Change Subscriptions button
log out, then do the yum_priorities

Page 3 before running yum update
you will need to remove some packages that will cause an error in the yum update.
go ahead and run:
yum shell
> install matahari
> remove matahari-service
> remove matahari-lib
> remove matahari-host
> remove matahari-agent
> remove matahari-net
> run
> exit

page 4 section 10
the three wget files were not found.
Use the ones you already have on the current servers. or find them somewhere else

Page 5 ruby download
the wget link is bad. use:
"wget http://fossies.org/unix/www/apache_httpd_modules/mod_ruby-1.3.0.tar.gz"

Page 7
the latest version of ispconfig has a bug in RHEL with fcgi that will prevent it from working without significant research so....
get the version I know is stable: "wget http://www.ispconfig.org/downloads/ISPConfig-3.0.4.6.tar.gz"
then finish up accordingly
when it tells you to leave the server name blank, enter your server name for ispconfig to see the server and change its settings within the web interface later.

Page 7 After the ispconfig installation finishes
if you did not enter a hostname when the installation asks, "Full qualified hostname (FQDN) of the server, eg server1.domain.tld [server1.example.com]:", you will get a postfix error. The ispconfig installer adds a bunch of lines at the end of the /etc/postfix/main.cf file. if you did not enter it you will need to add the hostname at:
myhostname =
at the end of the file. There is a commented out one in the middle of the file. If you put the hostname there and uncomment it, it wont matter since the hostname is reset to blank at the end of the file. Also the mydestination = parameter will start with a comma, as the ispconfig installer will add the blank hostname to the beginning of that line. The steps are:
emacs /etc/postfix/main.cf
Search for the "mydestination =" line
place your hostname before the comma, or delete the comma. (keep in mind what Till says below in response)
scroll to botton of the document and find the line: myhostname =
Add your hostname there: myhostname = yourhostname.net
restart postfix with "/etc/init.d/postfix restart"


To use a virtual IP in ispconfig you need to manually add the device
in RHEL: cd /etc/sysconfig/network-scripts/
cp ifcfg-eth0 ifcfg-eth0:0
emacs ifcfg-eth0:0
change the device name from eth0 to eth0:0
change the IP to the new IP
remove the HWADDR line
save

copy for other ip addresses you want to add.

/etc/init.d/network restart

I hope I didn't miss anything important. It can be a little frustrating working through it all and not knowing the differences needed for RHEL. I hope this helps someone.

 

I will remove it then. What I put in there for me was my actual server name, that is not a website domain. I just hated looking at the comma with nothing before it though. I'm not a sys admin, I'm a programmer.

 

Oh and by the way, The issue I was having with ispconfig 3.0.5 I think it was.... was with fcgi. I also noticed on my 3.0.4 server that some of the php code was causing errors, until I switched the site from fast cgi to suphp.

 

well thank you Till.

The error I was getting in 3.0.5 was causing the https://myip:8080 main page to fail. When I troubleshot it, it was a fcgi error I think, but I needed to move on and used the 3.0.4.6 version that was already running on another server. I read also many people were having the same issues after updating from 3.0.4 to 3.0.5.

The main error I received in the 3.0.4 fcgi page was due to a open_basedir issue after we moved our main website to the new ispconfig server from a plesk server. I cleaned up some relative path issues in that site and switched back to fast cgi, and everything seems to work, although I'm sure fcgi is not configured properly. I'm not yet even sure where the config files are.

 

I may have found my issue. Upon installing a third server I found a line I didn't update in the php.ini file. I missed the instruction, "and uncomment cgi.fix_pathinfo=1".
