I'm following this tutorial to setup a Redis server:
https://www.digitalocean.com/community/tutorials/how-to-install-and-use-redis
and getting this error message:
Mmmmm... the default config is missing. Did you switch to the utils directory?
I'm in the /utils directory, but there doesn't appear to be a default config. From the documentation I've read online, it seems like the config should have been created upon setup. Is this something I have to make manually or is this an installation error? My 'make test' command ran successfully, so I don't know why the config file wouldn't have been set up automatically.
If you're on WSL (Windows Subsystem for Linux), you can get this error if you put your Redis folder somewhere that has a path name containing whitespace.
So, like if you put it in the "Program Files" folder. I migrated mine out to just the C:\ drive (or /mnt/c/ for WSL), and it worked just fine.
Had to manually copy default config from the dir above into the correct dir.

Where do I put my rabbitmq.conf file and how do I make it known to the rabbitmq-server?
All documentation and what I can find only clarifies that this file is not there initially, and the example config file is referenced. Official doc says that I can override the RABBITMQ_CONFIG_FILE env variable. It is unset on my system, but how would I set it so that it is known to rabbitmq-server?
As #Taschi mentioned, the default location of the rabbitmq.conf file is /etc/rabbitmq folder.
Also, you can place it in a custom location and let the rabbitmq-server know the location by setting in in the rabbitmq-env.conf file.
Contents of rabbitmq-env.conf file
CONFIG_FILE=/path/to/rabbitmq.conf
Reference: https://www.rabbitmq.com/configure.html#config-location
By default, the location is at /etc/rabbitmq, according to https://medium.com/#lukaszlenart/how-to-configure-rabbitmq-properly-fa39b2d4cda2.
How to properly set the env variable depends on your operating system, but you could just do it in a startup shell script.

If installed via Homebrew you possible find the rabbitmq-env.conf file at
/opt/homebrew/etc/rabbitmq/rabbitmq-env.conf
One way to find out as well is to read the plist file to see the config location
Once you start rabbitmq via brew services start rabbitmq
It displays "rabbitmq started {user} ~/Library/LaunchAgents/homebrew.mxcl.rabbitmq.plist"
RUN: vim ~/Library/LaunchAgents/homebrew.mxcl.rabbitmq.plist
This should display certain file location such as config that you need.
Trying to get the sidekick image built and having some issues. Is there any documentation other than the README.md file?
My current problem is with getting the JRE requirement working but there are others. The page says "download Oracle JRE and place it inside the working directory. Optionally if you have a company wide distribution url, use that one at a later step." and the help says "Java (JRE) download url or path inside working directory". Have not been able to get this to work.
I went to the JRE link provided and was presented with options to download a rpm file or a tar.gz file. Which is expected (was unable to get either one working)?
It says to place the file in the "working directory" but not sure where exactly. Tried in sidekick folder and in sidekick/jre both without success no matter what I used after the -j command. Is this just the path or should the filename be included as well? Can I get an example?
I'm running this script using my login but noticed the output folder is being created with root user and group. I see no indication that this should be run with sudo. What is the correct way to run this script?
Using debug, I see the function "download if not cached". Can I save these files (JRE, Bamboo jar file, etc.) somewhere so I don't have to worry about downloading them? If so, where should they go? Looks like I might have a problem with the wget to d/l the jar file so would like to just be able to place all these in a folder and be done with it.
It looks like the major problem is the script didn't clean up after itself if it fails. The issue was the first time it failed then that caused subsequent issues as the output folder was already there. Removing this directory between each attempt help.
As for the correct syntax for the -j JRE option I manually downloaded the JRE and placed in a folder called per-build-container/sidekick/stuff/. For the command line it is not just the path but the file name as well (the tar.gz and not the RPM). For my case it was
-j stuff/jre-8u251-linux-x64.tar.gz
Note I also ran the script as sudo. Wasn't stated but seemed to work OK.
Another issue I ran into was the download of the agent jar file. There is a redirect in the wget file that was not working for us. I ended up editing the script and replacing the Altassian based url with the redirected one.
This addresses all the issues I ran into with the initial question.
The installation guide of Stackify states that we have to modify the catalina.sh of tomcat file to add the java agent. But in a spring-boot app, where can I find the tomcat location to modify the file.
I changed the application.properties file to set the custom location for tomcat by setting server.tomcat.basedir.
How can I change the catalina.sh file now?
Should be able to do the command cd $CATALINA_HOME/bin to get to the folder that contains the catalina.sh. After that you can add CATALINA_OPTS="$CATALINA_OPTS -javaagent:enter_path_stackify_apm_jar" to it.
I want to change the build dir of team city build agent to:
E://MY_PROJECT_SVN
While installing the build agent I set the same but it diaplays C://buildAgent/work in TeamCity web ui due to which my build fails.
My buildAgent.properties file shows
workDir=E\:\\MY_PROJECT_SVN
And buildAgent.dist.properties file shows
workDir=E://MY_PROJECT_SVN
But I get following error when I run team city
Failed to start MSBuild.exe. Failed to find project file at path:
C:\BuildAgent\work\3ac16e0b4e3af05b\Modules\SIM5.sln
Because of wrong working dir
The buildAgent.dist.properties is indeed just an example, but the solution is something you almost had; you need to put this into the buildAgent.properties:
workDir=E:/MY_PROJECT_SVN
Update:
It should be noted that on TeamCity 7.0 the workDir seemingly can't be on a separate disk; it runs most of the way through the build and then fails. However, using a junction to point from the local (default) folder to the E: drive will work. The tempDir can be pointed to a remote disk though.
The file buildAgent.dist.properties is not used, it is just an example. So don't worry about the contents of that file.
What you have set in buildAgent.properties is what matters. What is happening for you is the agent is reverting to the default location for the working directory.
This means that for some reason it is not able to read or parse the buildAgent.properties file. Make 100% certain that the entire file has no errors in it.
https://confluence.jetbrains.com/display/TCD8/Build+Agent+Configuration
Making any change to this file and saving it should cause the build agent to reboot automatically and reload the new config once it has restarted.

To build on paul-f-wood's answer:
Teamcity 9.1.6 also has the "feature" where the work directory cannot be on a different drive. I tried several permutations of the temp and work dir, and the only ones that stuck were with the work dir on the same drive as the root teamcity folder. However as paul said, using a junction works like a charm.
cmd: rm C:\BuildAgent\work
cmd: mklink /J C:\BuildAgent\work E:\MY_PROJECT_SVN
I'm running a java application that we distribute as a server-side system. I'm trying to write a launcher ("write" is somewhat of an overstatement here, I'm basically just copying the Java.exe file so that we can get the desired name in the process explorer of windows). This exe is in our bin/ directory of our application file tree.
Now, we also have a jre/ directory in our file tree, which is where Java.exe actually resides (we ship our product with the Java environment). When I use Java.exe as the launcher, which is located in \jre\jre1.6.0_21\bin, or if I place the copy (call this exectuable 'Orange.exe') I made in this directory, it works just fine. But, if I put my 'Orange.exe' in the bin\ directory, then I get the following error:
Error: no 'server' JVM at 'C:\Program Files\Java\jre6\bin\server\jvm.dll'
I think I understand what is happening here - I want to use the server version of the jvm.dll file, which is in our jre directory. The problem is, I don't understand WHY it doesn't look in the jre\jre1.6.0_21 directory in my application path. I've set my JAVA_HOME environment variable to this location. It seems like it's defaulting to another, system-wide expected location.
Does anyone know how I can change this, so that it looks in my application-provided java environment directory? Ideally, this will be an environment variable, as I need to call this application with parameters using a batch file.
There is a little trick to get the server JVM up and running:
Copy "server" folder from the JDK's JRE's bin folder example: C:\Program Files\Java\jdk1.6.0\jre\bin\server
Paste the "server" folder to JRE's bin folder example: C:\Program Files\Java\jre1.6.0\bin
Done
See official readme for details.
I've just been struggling with this same problem in Eclipse and I noted that as suggested by the answer above the JBoss site has a thread on this issue saying the same as the answer above to copy files from the jdk to the jre folder.
I noticed that you can avoid having to do this if you define the runtime to be the jdk when you create the server. I didn't find how to edit an existing server though.
AFAIK, the JRE usually doesn't ship with a server VM (only the client VM). If you really need the server VM, you have to use the JDK installation.
See Oracle Java for Developers Download page for JRE's with Server VM.
I had the same problem here but, in my case, I just had not properly update the JAVA_HOME and my PATH for my recently installed JDK.
I just updated it to my new JDK location and the server started just fine.
Windows looks for DLLs in LIBPATH environment variable.
And make sure your 1.6.0_21 is somewhere first in PATH.
I solved the same problem by setting the JAVA_HOME path to C:\Program Files (x86)\Java\jre1.8.0_131\bin
The easiest fix is simply to copy the contents of client folder inside bin and put in a newly created folder 'server' inside bin.
Copy from C:\Program Files (x86)\Java\jre1.8.0_261\bin\client
Paste in C:\Program Files (x86)\Java\jre1.8.0_261\bin\server
*server is the new folder
Make sure that server/jvm.dll file must be there when we are trying to run servers like servicemix.
Copy "server" folder from the JDK's JRE's bin folder example: C:\Program Files\Java\jdk1.6.0\jre\bin\server
Paste the "server" folder to JRE's bin folder example: C:\Program Files\Java\jre1.6.0\bin
I paced problem, I went through above..That's working fine.
Thanks!
