Server :: Unable To Add "apache" Service To Conga - Red Hat Cluster
Jul 11, 2010
I am new to clustering. I have created this scenario on VMware Workstation after reading numerous links and videos.
Few of them are
[url]
[url]
[url]
Code:
I am using a shared GFS2 filesystem mounted on /data for this purpose which is from openfiler.
Code:
I am trying to create a HTTP cluster so that if in case of one node fails
- Shared partition (/data) in my case gets mounted on the other node
- Also, HTTP services can be started on the other node.
/data has the index.html file which is read by HTTP. Also, I have configured HTTP such that it only listens to 192.168.1.100 (shared IP) on port 80.
Code:
I have configured the cluster, service "sharedIP" which has IP 192.168.1.100; I took help of this doc.
Code:
Member Status: Quorate
I have tested the service sharedIP failover by powering off the machines one by one.
I used the below command for failover
Code:
Now, I need to try running apache from shared IP 192.168.1.100 which will fetch file from /data/index.html
I tried no. of times to configure service and resource for apache.
But somehow, it is not happening. My apache bin is /usr/local/apache/bin/apachectl start|stop
I have given such long info to help some other newbie. I will certainly write a HOW-TO for this.

I came across this while trying to find a solution for my load-balancing clustering issue in another thread. Since I perceive this as something on its own, I decided to post a new thread. I came across this site to setup a two-server cluster using Conga - Luci and Ricci.
From my understanding, this is what was done:-
1. Both servers have luci running using a shared storage via GFS to provide a failover
2. Both (and same) servers have ricci agent running for the clustering
I'm aware that Conga clustering aim to achieve High-Availability.
1. Can it also achieve Load-Balancing?
2. If yes, would the guide from the link above be sufficient or would they be additional setup/pre-req to be done? Since I'm new to this area and there was no mention of load-balancing, I'm still wondering if this is what I need to incorporate.

I am working in a project that needs to set up an Apache Web Cluster. The cluster needs to be High-availability (HA) cluster and Load-balancing cluster. Someone mentioned the use of Red Hat Cluster Suite, but, honestly, I can't figure out how it works, I haven't been able to configure it correctly. The project currently have two nodes, but we need to support at least three nodes in the cluster.

I'm having a very strange problem with red hat cluster. After testing it in the lab, I tried to install a new cluster and received the following error: cman not started: Cannot start, cluster name is too long or other CCS error /usr/sbin/cman_tool: aisexec daemon didn't start I've checked the internet for that error, but nothing. I decided to to take the example from cluster.conf man, which looks like that :
[Code]...
And still I get the same error. I can find my servers both from DNS (FQDN and short name) and they also appear in /etc/hosts.

I am trying to setup Rocks Cluster on a Cluster containing 1 Master node and 23 slave nodes connected via a Switch. The master node's eth1 is connected to public IP and eth0 is connected to the slave nodes via the switch.
I was able to install the Rocks cluster on the machine, I configured the IP for master through DHCP. When I run the command 'insert-ethers' on the master node, it doesnot get me any slave nodes.
setting up the Rocks cluster on all the nodes?

I am using the Redhat Cluster Suite (luci and ricci) on my centos 5.4. i have 2 nodes in a cluster.I had clustered an apache server.The service is up end running and i can stop,start and switch on all two node.The problem is when i try to simulate a fault for one node.For example:The apache resource stay on the first cluster node.If i power off the first cluster node (not halt or init 0 but take off the eletric power off), the second cluster node not take the resource.With the clustat command, the service still running on the first node.But the service is down. The first node is dead.Only one the first node is join again the cluster the resource goes up on the second node.

I am trying to do the cluster storage with the Rock Cluster storage operating system . I have install the rock cluster on the main server . and I want to connect the client with the PXE boot . when I starting the client then it boot from the PXE boot into the mode of compute node. but it ask the where is to be stored the I have give the path..then server says that not able to find the directory path.
Steps:-
1) insert-ethers
2) client is started with the PXE boot.
3) it detects the dhcp .
4) At last it demand where is to be started by cd-rom, harddisk ,nfs etc.
then I started with the nfs and I have given the lanIp of server.and server is detecting the client but client is not finding the filesystem directory. into export partition directory but it is not taking path.
PATH:-
/export/rock/install it is not finding this path then it is not able to start the o/s from PXE boot..Is there any solution and manual of rock or anyother solution then u can reply to me...

I am familiar with windows 2008 cluster servers, and I just started testing with centos cluster. I am creating a simple 2-node cluster, for a simple ping test.
Node 1: 10.0.0.1
Node 2: 10.0.0.1
Virtual ip: 10.0.0.10
So far, I can ping a virtual ip, and manually relocate it between the nodes, but I didn't figure out, how to do this automatically. So this is my question: How can I setup the cluster, to it automatically failover the a service to another node case one node fails?

I've tried on both 10.04 and 10.10. I apt-get install apache2, and put a simple "hello world" perl script in /usr/lib/cgi-bin, but when calling the script via the webserver I get a 404 "file not found" error.
/etc/apache2/sites-available/default already contained (out of the box)
Code:
ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
This used to work out of the box in the days of the older monolithic apache. What configuration has to be made to enable scripts to run?

I am very new (since yesterday) to Linux also new to web server setup. I have installed all LAMP components, including SSL as described here: [URL]. I have added LISTEN 443 Wanted to restart the apache server -> no success ! stopped it, now doesn't start at all:
Warning msg=>
(98)Address already in use: make_sock: could not bind to address 0.0.0.0:44 no listening sockets available, shutting down . .
Failed
I tested Apache and my PHP earlier and it worked. Now after SSL and FTP installation it doesn't work anymore! Also I am wondering about my server name, it is the set IP of the web server, surly i should change that? Only used link for SSL set-up, used diff links for apache php etc (also have java JRE installed as I will need that later for my app) also have GNOME available, but prefer command line.

I am a newbie to linux of 4 weeks. I set up my first web server and it works flawlessly - when accessed from external network or from other computers on my lan. However, I cannot access it from the computer where the server is run on. I have found numerous people with similar problems but the flavour I am experiencing is somewhat different and no solutions I have found apply to it.I have two network interfaces on my server, eth0 (public static IP connected to internet) and eth1 connected to LAN 192.168.1.0/24 range. The server is 192.168.1.1
I added "192.168.1.1 www.server.com" to the /etc/hosts on the server and also on the other machines on the LAN. All the other machines can open website without any problem.
HOwever, the server itself only opens website if the address is localhost. Internal IP, i.e. 192.168.1.1. gets a time out and so does www.server.com.I do not understand why the record in etc/hosts doesn't point it in the right direction. It seems that when I open address 192.168.1.1 it still gets routed to the external network. I have seen using DNAT to deal with the problem but it didn't work in my case (maybe I didn't do it correctly). I have spent whole evening/night trying to sort it out, it's 4AM now, going to bed frustrated and angry (at myself hahaha). Still like linux very much, won't be going to windows anymore. Please help

I have a nagios server monitoring around a 1000 hosts in our office. To make things easier, i've integrated apache into Active Directory for the website authentication. This works perfectly, however the Nagios website uses alot of CGI scripts to display information I get the message below when trying to show CGI scripts with an AD user. Local users work fine. 403 Forbidden You don't have permission to access /nagios/cgi-bin/status.cgi on this server. I tried adding the AD users to the cgi.conf file within Nagios (which works for local accounts) but it doesn't seem to work even with this change.

I suspect that this has come up numerous times, but I am new to Linux and I am setting up a new in-house server using Ubuntu 9.04 and Apache, etc. I can see the welcoming "It Works!" message when I log in via Firefox. I can see "index.html" when I FTP the server with the site name and password at /var/www. I can also see the -rw-r-r-- attributes, but I can't edit the HTML file or replace it. When I try to rename the "index.html" file.
I get the following message: "Request denied. Verify that the file or folder exists and that you have the necessary permissions on the server to perform the requested operation."
I haven't been able to determine where to enter the password or what changes I need to make to be able to work with the /var/www directory via FTP.

I am running opensuse with LAMP, and this is my first time setting up this type of server (usually am a windows junkie) My problem i am having is that I am unable to view my website from outside the local network. I have setup my router for a dynamic dns and forwarded all the ports through the router and the local firewall. I ran the apache setup through YAST2 and everything seems fine locally but when i attempt to access it elsewhere its not connecting. computechsolutions.dyndns.biz is the dynamic dns address i have setup through my router.

I have recently ported from Windows to Linux (xubuntu) I am a developer, i installed everything i need, LAMP. Now in Windows i used to turn off all unnecessary Services, i don't need the Apache or MySQL service running all the time. I used: net start mysql
Whenever i needed it. How do i do the same in Linux:
1. Disabling not-needed daemons from auto-starting?
2. Starting them only when i need them?

I tried creating a virtual server in apache and it got created successfully. (I also added a zone in dns for that domain successfully) However, when I try opening that domain in my browser, I see a popup window which asks me what to do with "default" which is a php file type.
I dont see the index.php which should actually open. What do I do to make the php files display correctly?

I am trying to build GFS2 cluster with 2 or 3 Fedora 14 nodes, but I've encountered some problems from the start. First luci does not work at all in Fedora 14. There is no luci_admin and even if I manage to start luci service, I get a blank white screen when I try to open it from the browser. I've googled a bit and found that I'd might be able to setup GFS if I manage to build cluster.conf manually and start the cluster suite, but I cannot find documentation on how to create cluster.conf anywhere. If anyone knows how to setup GFS2 without a cluster suite or how to configure cluster.conf.
