Red Hat :: Turning Ruby On Rails Ubuntu Command Into Redhat Command
Dec 2, 2008
I'm the noobiest noob you'll find on here. I'm having trouble getting ruby on rails to work with mysql on redhat. So on their forum I asked how to install the latest "sqlite" database package on linux.They told me to run.Now, I don't think I need "sudo" because I am the root user on my database, and I don't think I can use "apt-get" because I'm using redhat, not ubuntu.
1) Is there a way of running the above command on redhat? (A redhat command for installing things?)
2) How can I be sure I'm using redhat and not some other OS?
The site that used to host the language spec file for .erb/.rhtml for ruby/rails syntax highlighting is no more.If someone could attach the file for gtksourceview-2.It's located in /usr/share/gtksourceview-2.0/ language-specs/ and probably called rhtml.lang
I'm going through the Beta version of "Agile Web Development with Rails - 4th Edition". But I'm having difficulty with initial configuration on my Gentoo box. I started like so, basically following the book:
Code: $ rails testrails $ cd testrails $ script/generate controller Say hello goodbye
I'm trying to install ruby on rails on Ubuntu 9.10. I'm following the instructions on this site: http://castilho.biz/blog/2009/11/05/...-karmic-koala/
However, when I try to install Rails I get an error code...
It seems like gem can't access http://gems.rubyforge.org/gems/rake-0.8.7.gem for some reason, but when I try to go directly to that address I get the option to download it. Any ideas how to get around this problem?
I'm thinking if I can somehow tell gem to look for the file locally I can download it and install rails that way.
It is little weird now that cron job is not working as i have set. I have set weekly job to send email but i am receiving multiple emails daily. Below is my code; # sends email every monday at 4:00 am 00 04 * * 1 /usr/bin/ruby /home/mbm/www/current/script/runner /home/mbm/www/current/app/models/add_to_delayed_job.rb -e production
00 -> Minutes 04 -> Hours (0-24) 1 -> Days / 0-6 / Sun - Sat
Sending email is fine but the time is not working so far as set.
Maybe it's just the program i downloaded and maybe something's missing, but when I run ./configure I get the error: ./configure: line 4: ruby: command not found it told me to try cnf configure and it says no such file Is this me, suse or the program I downloaded? Something's wrong here.. Maybe ruby needs installed?
Would a representative from each Linux distro be kind enough to tell me what the command is for installing the Ruby interpreter in their distro? In Gentoo it is "emerge Ruby".
I am attempting to start ruby in interactive mode from the command line. However, when I type ruby at the command line, it simply hangs. I know that I have ruby installed. Any ideas as to how to resolve this problem.
I want to know the exact command to shut down a red hat linux server.I was using init 0. but some one said its not the proper method to shut down my linux server.If not which is the exact command
I have a program which mounts /dev/sdb1 for which I lack the source code. This device does not exist on my RedHat 9 system and I want to create /dev/sdb1 such that it's an alias for /dev/hdb1 Can I do this? with MAKEDEV?
I need to have an alias which will allow it to mount, not create a symbolic link to an already mounted directory. i.e. 'mount /dev/sdb1 /mnt/harddrive' should actually mount /dev/hdb1
i hope i'm posting in the right forum "Networking" subject related to remote onnection.. all the suggestions and solutions i found on the net did not do it for me..i have redhat(EL v4) and hp-ux(11i B v23) servers
i'm able to use remsh from hp-ux to hp-ux with the command hpux1_srv> remsh hpux2_srv -l hpux2_user uname -n with remsh from hp-ux to redhat it gives permission denied.
I have a 2 node RH 5u4 64-bit. I have installed and configured the latest Veritas CFS (Cluster File System) which also uses Veritas Cluster Server. File system if VxFS. Storage is on EMC Symmetrix arrays with Veritas Mirroring between the arrays.We have noticed that running 'du -hs' on the shared directory/filesystem where it takes about 3 minutes on one node and 30 - 45 minutes on the other node.I've been running strace on 'du'.'du' runs an 'lstat' on each file (66,000+ files). On the slower node, the ave time spent in 'du' is about .001 seconds longer, which accounts for the 30-45 minutes. Also, the standard deviation is much larger, which means to me that the lstat times are all over the place!Another interesting thing is that iozone profiling shows that the i/o rates from both nodes are darn near identical, with no anomalies at various buffer & file sizes! And, iostat looks really good as does 'vxdmpadm iostat show
I've been using rubyripper quite happily on Karmic, now I've moved to Lucid and discovered a bit of an issue. rubyripper will pause for several minutes between tracks with ruby 1.8. If I upgrade to ruby 1.9.1 the gui client won't run due to an issue with libgtk2-ruby not being available for 1.9.1.
The cli version of rubyripper under 1.9.1 is blazingly fast, so that is what I'm using at the moment, but I do prefer the gui.
Anyone have any insight into this? Googling suggests there may be a bug in ruby 1.8.7 that caused the long pauses, but it was supposed to have been fixed in 1.8.7.249 i.e. the default Lucid version.
There are a few things not working properly. Ruby version manager seems ok but untill i get working with ruby i don't know if it is working properly. One thing that is not there is irb Interactive ruby is not available according the the message i get.
Well i have no idea what readline is but i did everything that is on that webpage referance page [url]. I have got a lot of progress and learned heaps about linux shell and bash terminal. The thing is i need to get this going and have tried feenode but it is very foreign and how it works i do not have a clue. I have got 2 things resolved so far through this forum but using other threads in it. i need to get irb going before i can progress to using ruby on Rails properly.
I am using a Eeepc running ubuntu easy peasy its version 9.04 of ubuntu. I need the whole of rails to work and want to get a handle on using ruby version manager along with the apache stack with mysql/phpmyadmin and am using this as a dummy run for setting up a development system.
i've gotten my fedora 12 to the point where i can run python3 scripts from command line and can call up python 2.6.2 idle with the command 'idle' from command line. what command will call up python3 (3.1.2 to be exact) idle?
I know my way around MS Windows much better, but I just don't feel right trying to program something for Android on a Microsoft operating system. I am interested in Android programming so I followed the instructions on [URL] to install the environment on my computer...
I just installed the JDK, SDK, Eclipse successfully (or I assume):
* When I get to Step 4 where I'm supposed to run 'android' it will not run. I get the error message "android: command not found" (I am definitely in the right directory).
** When I double-click it in nautilus, it opens up in gedit. I can set the permissions in nautilus (through the properties - Allow executing file as a program) and get it to work,
I just recently learned about the wonderful little lpr command- and using man -t (bash command) to beautifully print man pages for reference- but is there a way to print both sides of the paper using a printer so equipped?
how to pass something more than a one-command startup for gnome-terminal. I will give an example of what I'm trying to do here:
Code:
#! /bin/bash # #TODO write this for gnome and xterm
[code]....
This same error occurs if the gnome-terminal line is changed to
Code:
gnome-terminal -e mcTerm
Is there any way to pass more than one command on to gnome-terminal? I have tried various single and double quoting senarios and in a final attempt, I abstracted to an exported function all to no avail. Perhaps even though gnome-term is better at many things than xterm, xterm trumps it in this instance.
I have a big bash script ,its goal is to download movie one by one . But I often get into a problem: if this script is executed in cron,it often does not completely download the movie.I often find the movies it downloaded are several KB while the movie is actually 20MB.So I think it is because it did not wait for finishing one task ,and jump to download another.So I want to know ,is there a way to force the bash script to wait until one movie downloaded completely and then start to download another movie ?
want to know if Ubuntu provides a command to search for a command having a specific word.e.g.If I know a command contains editor as a substring but don't know exactly what the command is,then is there a way to find that command or the list of commands having editor as a substring.
In Ubuntu 10.04 grub command prompt setup command does not exist for installing grub.I am trying to recover my Feodra12 OS.Did anyone find alternate command for setup in grub command line for Ubuntu 10.04 ?
$cmd If this script is executed, an error is generated. The reason written was that "The execution fails because the pipe is not expanded and is passed to date as an argument".What is meant by expansion of pipe. When we execute date | wc on the command line, it goes fine.then | is not treated as an argument. Why?
I am using openSUSE 10.3.When I install software from tarball then to record time required I send output of date to beg.txt(when installation begins) and end.txt (when installation finishes).How can I append output of date to a file so I don't need two files?
