Ubuntu Servers :: Scritp To Few Seconds Before Executing Next Line?
Sep 29, 2010
I have a script which copies(scp) .war file to tomcat's webapps and the .war file extracts creating a folder under webapps directory on a ubuntu system. My next line of the script is restarting the tomcat which is executed immediately before the .war is extracted and this causing problem with
Is it possible so that it waits for few seconds/minutes before it executes the next line of the script. The script is of normal ubuntu commands.
I have a php file that I need to execute via a cronjob. This file should be run by the www-data user as its a file in my /var/www/project folder. When I run this file under root (php -f cron.php) everything works perfectly, but I want it to run under the www-data to be safe. Before I run it vai crontab I tried it via command line as the www-data user and I receive errors:
Fatal Error: Allowed memory size of 8388608 bytes expired (tried to allocate 232 bytes).
But when I run it as the root user I get no errors and everything works correctly. The file cron.php is used to process automated tasks in my CRM. So I don't really want to have the root user running a crontab every few minutes for this.
Must the www-data user be given more permissions? I am using Ubuntu 6.06LTS PHP - 5.1.2 Apache - 2.0.55 MySQL - 5.0.22
I'm have much computer experience but am new to Ubuntu. I typed in sudo apt-get install ubuntu-desktop and it tells me it's already installed. Good. So it should work. I type sudo/etc/init.d/gdm start and the screen goes blank for 8 seconds three times in a row and then back to the command line. I have also tried gdm start without the path before and it says GDM already running. Aborting!
I upgraded karmic to lynx today and I'm stuck with some weird behaviour with one of my virtual hosts. The virtual hosts under /var/www/site work but my virtual host for DAVICAL which points to /usr/share/davical/htdocs/ doesn't.
Navigation to any html pages works but php files just show up blank!
Has there been a configuration change in lynx for virtual hosts outside of /var/www?
I am trying to get a start up script to work, I have a file /etc/init.d/blah (with 755 permissions) with the contents [URL]. I have run "update-rc.d -f blah defaults". But when I reboot the script is not executing.
I extracted the Drupal package (6.20) to /var/www/html and followed the provided install.txt file, but whenever I try to navigate to the site it simply comes up with the PHP script as plain text (it does automatically redirect me to install.php) rather than executing it. PhpMyAdmin works fine, as does a simple PHP "hello world" page I made, so I assume PHP isn't the problem. Now my question is: what could be causing this?
I can't tell for sure if the problem's with Drupal itself (I started over once with no luck) or some setting on my system, but since I don't have an account there I figured I'd ask here first.Running F14 x64, Apache, PHP and MySQL are all at latest versions available.
I have written a simple backup script, and added it to CronTab, but it doesnt execute at all. Here is my script: [URL]...And my CronTab entry: 0 */2 * * * root /home/server/Scripts/backup.sh
I run KVM on 9.10 host and guest 9.10. Both are x64. When I halt the guest os: My host OS looses its connection with internet for 10-15 seconds and then it comes back on. Probably something goes wrong with default gateway, as it looses only external network (I still can reach it on my internal network). I've googled a lot, but cant find anything about that. I use bridged network.
I'm sorry if this has been posted already but I REALLY did look and couldn't find the same issue(s) addressed anywhere. Similar, but not similar enough, in my opinion, to barge in and switch the subject.
Ok, I have Apache httpd set up so I can use a public_html folder inside of my /home/username directory. Now, I'm about to take a web dev course that teaches JSP/Servlets for building web applications and I'd like to set my environment up so that I can execute .jsps from my web root (/home/username/public_html) just like I would a CGI or PHP script. I have a web host that will give me JSP support for a few extra bucks a month, but I'd rather do it locally... and free.
I have Tomcat installed and running wonderfully. The test page and all the examples work fine and execute immediately. But when I try to execute a .jsp file inside of my web root (/home/username/public_html) I just get the raw Java tags and plain-old HTML rendered in my browser. I pretty much knew that wouldn't work; that'd be way too easy. I just wanted to see what would happen.
I looked through all the tomcat ".conf" files I could find to see if it was similar to setting up httpd inside of my home directory, but I didn't have any luck. It's not a file permissions problem... I've been messing with web "scripts" long enough to check that the files are executable. All of the files needed (borrowed from the examples that come with Tomcat) were in their correct paths inside of my web root, as well. Added :8080 to the end of localhost (like you do to see the Tomcat test page(s) instead of the httpd test page) but that didn't help.
I scoured the web for directions but could only find one solution that was Ubuntu-specific (just install tomcat6-user-something-or-another.deb, which doesn't exist in the Fedora repos), then I looked around here, trying every search term that seemed reasonable to me, and I can't find anything.
I realize I can just write the code and put it in a directory that does allow these things to be executed (var/lib/tomcat6/blah-blah-blah/going-by-memory) and run them from there, but I'd like to be able to just keep all of my web files in the same place; a place where I have full permission to do whatever I want... my home directory public_html.
Is this possible (has to be, right?)? Is this a dumb idea to begin with (I'm prone)? What is the best way to develop JSP/Servlets without having to deal with permissions every time I want to put a new script in a directory outside of my home directory that's already set up to allow the execution of said script?
I'm out in a village and we get more powercuts than I like, and recovering the journal on my server is getting rather irritating. I'm looking into getting a cheap UPS, the powercuts will last usually a maximum of 30 seconds, so I only need a few minutes.
I've been looking at:Plexus V 500VA UPS Plexus V 1200VA UPS APC SUA750I Smart-UPS 750VA
I know near to nothing about these things, my question is will those work with a machine with a 700W PSU? How do you know? The 500VA doesn't really mean much to me. Ideally I'd like to get my desktop on there too, but that's more for convenience than anything.
Will any of these do the job? Any Linux compatibility issues I should plan for? Any recommendations from personal experience is greatly welcome Edit: I will be happy with a UPS that can inform Linux power is down, and get the server to cleanly shutdown straight away, I'm more interested in a clean shutdown than maintaining power to use the machines during the outage. Edit 2: Can UPS devices be piggybacked to one another to provide extra uptime? i.e. Could I run 2 of the 30's so when the first runs down, the 2nd carries on?
My system clock loses about 10 seconds every minute. The hwclock is fine. I've tried different kernel args (clocksource=acpi_pm, nohz=off, highres=off). None of these have any effect. I am running Fedora 11 with kernel 2.6.30-105.2.23.fc11.x86_64 on an AMD Istanbul node (Processor 2439 SE).
I'm looking for a way to automatically convert XLS and XLSX files to PDF when uploaded through a Web interface by users. I will probably use phplivedocx for DOC and DOCX files, but I haven't found any library for Excel files.I may use PHP to call a some printing command to make the conversion, but I've never tried that on a server (which obviously) doesn't have Open Office installed (meaning no PDF printer driver I guess)
I was just having some trouble getting an OpenPHP Key on Ubuntu Server. The link from Launchpad said, "go to applications..." but I'm not using a desktop environment, so I had to go to [URL] to learn how. Basically it boiled down to this:
I just got done installing Ubuntu Server 10.04 on a home server. Now what should I do? I was hoping to have 3 computers connected to it so that we can all share files wirelessly if that's possible.Does Ubuntu Server have a GUI or command line only?
I had some trouble before getting to install Webmin on my nas from the command line in Ubuntu Server So I wanted to temporary install a gui and used kde. Downloaded it via the browser.Now I got webmin running and tried to remove KDE again. Some things were removed but the inlog screen is still there, and now it looks more like a gnome interface when I logged on.How can I remove the GUI completely again?
Some time ago I installed LAMP in my server, but now I need to execute .php files from the command-line (in order to execute some manteinance scripts for mediawiki). Seems that the PHP files running in the server are run thru some kind of "module" in apache2. Can I tell apache2 to run a .php file in command-line mode using that php module? Or should I install a fresh copy of php-5? Won't that interfere with apache or mangle the system?
how to set up a simple rule on the server side so emails with a certain subject just go into that user's .Trash. Right now my users will get roughly 25,000 of the same email from our corporate offices and it is destroying their email clients. I believe the mail setup is postfix and courier with virtual users. I tried googling this up but I couldn't find much current or ubuntu-specific information.

Very cool news on a small patch that apparently works wonders with the linux scheduler. Click here to see Phoronix testing of new 200 line Linux Kernel Patch shows it does wonders for performance
I'm installing a 10.04 server remotely - it's basically an RSYNC host for backups. I've got one minor issue - it's really more of an annoyance, but I would like to have it solved.When sending e-mails, the messages come in addressed to three destinations - when it's only supposed to be sent to one. What's worse is that the two additional addresses are based on the hostname of the machine.Let me explain: I use this command:Code:mail -s Testing email@somedomain.comI then compose the e-mail and send it. The mail arrive a few seconds later but addresed to the following:Code:from@hostname.domain.com;email@somedomain.com;hostname@hostname.domain.comThe "from@hostname.domain.com" has the actual word "from" in the address. I've installed many, many servers like this in the past and this is the first time that anything wonky with email has happened that I couldn't fix or explain. The machine is running postfix and I installed the bsd-mailx package to get the command line "mail" command (I used to install "mailx", but this seems to work just like the old package).
I have a headless server set up with no GUI on board.I know there is some way to display the installed hardware , I just can't remember how.What I'm looking for in particular is determine the type and speed of the PCI-e slots.
Is it possible to complete a drupal installation and change the configuration from the comman line or a script. Id like to be able to automate the process of installing and configuring drupal. I should say that this is quite a bit beyond me. Ive not long started learning scripting.
I'm using my home server to netboot into live CDs. To summarize that article, netbooting a liveCD system involves passing an NFS host:/path in kernel's command line, which is subsequently mounted as /cdrom on the live system. The article mentions copying the contents of the iso image to a place on the hard drive, but I see no reason for this, since the contents need to be read-only anyway, which is easy to achieve by mounting the iso through a loop device:
Code:
# mount ... /dev/loop0 on /mnt/kubuntu-lucid-amd64 type iso9660 (ro) /dev/loop1 on /mnt/kubuntu-natty-amd64 type iso9660 (ro)
[code]....
Now, I am using NFS to mount a regular (rw, HDD) directory which I use as a network drive and I can mount any subdirectory and still access all the files within, ie. when I export /data on the server, I can still mount /data/downloads on the client:
I have two files, file1.traj and file2.traj. Both these files contain identical data and the data are arranged in same format in them. The first line of both files is a comment.
At line 7843 of both files there is a cartesian coordinate X, Y and Z ( three digits ). And at line 15685 there is another three digits. The number of lines in between two cartesian coordinates are 7841. And there are few hundreds of thousands of lines in a file.
What I need to do is copy the X Y Z coordinate (three digits) from file1.traj at line 7843 and paste into file2.traj at the same line number as in file1.traj. The next line will be 15685 from file1.traj and replace at line 15685 at file2.traj. And I dont want other lines (data) in file2.traj get altered. This sequence shall be going on until the end of the file. Means copy and substitude the selected lines from file1.traj into file2.traj.
I tried to use paste command but I cant do for specified line alone.
Here i showed the data format in the file. I used the line number for clarity purpose.
setup a number of shared drives for accessing music, movies, photos and general files (documents, pdf files etc). now while a gui would be great, how to use the command line to setup these shared drives and also how to make the available in both windows and linux.
On Ubuntu Desktop editions, there is a GUI application which allows easily changing to a different server. It can even find out how one is the fastest update server.Is there a corresponding command line tool available to do this? Because I'm using the Server edition without GUI. I hate to manually edit /etc/apt/source.list.
