Ubuntu Servers :: Starting Multiple Programs At Boot On Server
Feb 11, 2010
Running Ubuntu Server 9.10.I have a couple of programs that I would like to start at boot, they will both run forever. I have created a cron job with @reboot and that will start a program, but if I have multiple programs in there it waits for the first to finish before starting the next.
How would I make sure cron is running every time my server is turned on? I want to make cron jobs, but I need to know that it is running when the server boots. Also, I used a program at some point that was terminal based and it showed be what programs ran when the server booted up. It allowed me to check a box and select which programs I could run at boot. If someone could tell me this program,
I'm curious if anybody can shed some light for me in this department. We're in a large environment with a Windows DHCP Server. We have been tinkering with LTSP on Edubuntu as thin and fat clients. It works great, but right now we just have 1 server handling the lab, which works fine unless we want to expand, which may be very possible.
These are the instructions I received: Login to your windows server and load the DHCP configuration screen Create a DHCP reservation for the MAC address you obtained Add the configuration options below to enable the machine to boot from the LTSP server 017 Root Path: /opt/ltsp/i386 066 Boot Server Host Name: <ip address> 067 Bootfile Name: ltsp/arch/pxelinux.0 # Specify CPU architecture in place of 'arch', for instance 'i386'
I'm curious, what if I want to have multiple Ubuntu servers on the network that I want to have bootable? For example, let's say I have 3 labs, and 3 servers. Server A to Lab A, Server B to Lab B, and Server C to Lab C. I want all C's computers to boot to C, and B to B, A to A, etc.
1 - How would I add multiple entries on the Windows DHCP Server to allow all 3 (A B C) servers to boot?
2 - How would I be able to isolate the clients so ONLY Lab A clients boot to Server A, etc?
I recently installed an Ubuntu 10.04LTS server. I have zabbix-server on that machine, and I noticed that after reboot it won't start. Probabily, the mix of upstart and old init.d scripts result in zabbix starting when mysql is not active yet, in fact in zabbix-server.log I see it cannot reach db. How can I make sure zabbix-server waits for mysql?
I'm looking at setting up a couple automated systems: Here are a few examples:
* Internal accounting system to download and process emails * Public web server to visit
I could put each system on its own separate box -- for example, it's generally good practice to separate anything that external users have access to (such as a webserver) from internal processes such as accounting. Now, rather than dishing out the money for two separate servers, could I get away with just installing new instances of VMWare on the same box for each system?
To give you an idea, these are not large scale computationally sensitive systems. The accounting one is simply downloading and tallying emails, and the latter is just a webserver with maybe 5 hits per day on a good day. I could definitely pick up a new box for say $50, but I wanted to know the general practice of using VMWare on the same box versus two separate boxes.
Since I have not gotten anything on the "General Help" I am posting this here: When a Ubuntu 10.10 I have starts up apache2, MySQL and postfix start properly but bind9 doesn't. Once booted is I run 'sudo /etc/init.d/bind9 start' it starts. The only thing odd on this system is I have a "inet6 v4tunnel" interface defined in my /etc/network/interfaces. From booting in the syslog there is:
Even with the bind debug level at set at 90 I do not get any more in the logs that what I posted before. The lack of errors in the logs is giving me no idea where to start. I commented out the IPv6 tunnel interface and rebooted and still no help. bind still is not starting at boot. OK, it is not a permissions issue, I have changed the config and zone files to be owned by bind:bind, root:bind, root:root and bind:root and it has made no difference. Doing a fresh install on a Virtual Box VM and configure it in a similar manner bind9 starts normally. (I am almost to the point where I will rebuild the box)
I have a file server running samba 3.4.0. I just upgraded ubuntu to 9.10. The upgrade was unfortunately stopped in the middle, but I think I managed to complete it.The problem is that now samba will not work after a reboot. The daemons are running, but any attempt to connect from a windows machine fails (Windows 7: the network path was not found). Manually restarting the service fixes the problem, but I need a more stable solution!Interestingly, I can ssh to the machine, or rdp to a virtual machine running on it.The logs don't seem to report any error:
I am trying to get SQL-Ledger installed and running on my computer, which needs PostgreSQL installed to run.Currently, I am having trouble with it starting at boot-up. How can I access the appropriate log files in order to figure out what's wrong?
Also, I need to know what httpd is, and who the owner and groups using that might be on my system.
I am currently using FC10 on a Dell 4600 with 2GB of ram. I love Linux as it is the most stable OS around. My end goal is to have the machine boot and start the vncserver automatically, eventually using an ssh tunnel to make it secure. My main problem is the vncserver is not starting on boot, I must login as a user then it works great. the error I get is
Basically what happens is the vncserver fails on boot however, if I login to the Fedora box I am able to connect and I get the GDM login screen. I have read many, many posts but have not been able to get over the boot issue. I really want to make this a headless box I can put in another room so I have more room for my musical gear.
Just upgraded to F15 and I cannot seem to get the sendmail service starting at boot time.It starts and works just fine by hand after boot, so there's nothing wrong with the sendmail configuration itself."runlevel" shows a current run level of 5 and "chkconfig" shows sendmail on for run level 5.All the other mail service (mailman, clamd, etc.) start fine.Doing "service sendmail start" after boot gets everything up and running just fine, but itsure would be nice to have it run at boot like it used to
I'm trying to run BoxBackup to sync a couple active servers to a data server. I installed the server and client, making sure to follow the instructions closely with all the certificates. The problem is the service daemon on the service won't even start. The service manage reports: "bbstored dead but pid file exists" (basically, tried to instantiate the process, but it died due to faults).
Here's the log of the daemon in /var/log/box

I am trying to share files between Windows XP machine, ubuntu server, debian server and ubuntu desktop. But mainly between ubuntu server and Windows XP computer.I also like to learn samba, because probably I could do all this with ftp server as well.I set up and configured samba following the instruction on Online Ubuntu Server Guide.But when I run the command:sudo /etc/init.d/samba restartI get:bash: /etc/init.d/samba: No such a file or directory I don't know what is wrong?
One of my ubuntu 10.04 boxes starts apache2 server automatically at boot. I know from the output of the command:
sudo /etc/init.d/apache2 status
I can't remember even setting that up, and I don't think it does so by default, since my other box in fact does not even have apache2 server installed. I can stop the server once I login, but is there a way to stop it from automatically starting the server, or even better, completely uninstall the daemon. I tried
sudo apt-get remove apache2
but that does not work. I guess the daemon is part of some bigger package.
I'm curious how I can use a Windows client with two separate accounts to connect, at the same time, to a SMB server hosting two shares. (Provided permissions and accounts are all in order)
Scenario:User1 is always logged onto a Windows client mapped to a Public share on a Linux SMB server.I need a way to keep User1 connected to the Public share and then when needed, allow User1 to provide User2's credentials to connect to a Restricted share.The only way I've been able to do this is to disconnect from the Public Share then reconnect to the Restricted share using User2's credentials. (This is the issue because I need to keep User1 connected to the Public share).Is this a limitation of SMB? Or am I missing a configuration? Please point me in the right direction
create an Apache web server with multiple user accounts, for work. Each user needs to be able to upload his/her files via SSH Each user needs his/her own web directory, (preferably in their home directory for ease with permissions) There web directories need to be password protected Only one user account (mine) should be allowed remote SSH control. It needs to be easy to add new users to the system.
Recently I've been earning money doing web development, php, html/css, MySQL and so on. What I have encountered a lot are clients that need a complete solution. They need their site built, but they also need a hosting solution. I've sent more than just a few clients off to GoDaddy, and quite frankly, I'd like to cash in on some of that.
It would do wonders for my business if I could offer them a hosting solution with full support on top of building their site. My problem is I have no idea how to do this. So I'd like to know how I can host multiple sites on the same server. Does anyone know of a nice guide I can follow to set this up? It's really important that I can add sites fairly easily over the internet. Since I will be away at school, I won't have direct access to the server
I work for a college with many departments. I'd like to just deploy one LDAP/krb5 server (plus slave replicas) to authenticate all users in all departmentsIs it possible to do this?The proposed DNs for the departments matches what is done for NIS now.If anyone has any pointers or URLs that describe how to properly do this.
I am currently working on managing multiple linux servers in remote locations, servers particularly user for web hosting. I need to backup data to a backup server but rsync which i currently using doesnt helps is there any tool to backup every server with out modifying it bcos there are hundreds of servers so installing a tool in every server is time consuming process.
by now I have 10 servers for hpc, power computing oriented. My users need to launch several processes using qmake. The users are used to work with ubuntu 9.10, and the software from the repositories is switable for them. I've deployed ubuntu 9.10 to all 10 servers (pxe rocks). By now we work with parallel-ssh and cluster-ssh, which allows as to launch the same process to all servers. With this tools this tools the servers remain as independent but with the same software and the same launched command. Now we would like to go to next step and see all the servers as a single one with all the resources from the other 9 as if was its resources. The difference would be substantial in time to process and also time to design the command to launch.
Im moving all my websites on a dedicated box. I had a cpanel hosting account, and now moving to a terminal and ssh system.I need some advice on choosing my mail setup. I need POP, SMTP, with multiple domains, as host for a few clients.I would like the most simple version.The server will only send +- 100 mails / day.I currently running Ubuntu Linux 10.04.
I have recently setup an Ubuntu 10.04 Minimal x64 Server. I plan on setting it up as a mail server. I need a secure server, that has spam prevention on it. Im setting up around 50 domains and would like a web based control panel. What is the most secure mail server, that i can setup for multiple domains?
