When Installing JIRA Data Center On Linux The Installer Fails Saying It Cannot Run Its Internal Java From /tmp

Introduction

When installing JIRA Data Center on Linux, users may encounter an issue where the installer fails to run its internal Java from the /tmp directory. This problem arises due to the /tmp directory being mounted as noexec for security purposes. In this article, we will explore the reasons behind this issue and provide a step-by-step guide on how to overcome it.

Understanding the Noexec Flag

The noexec flag is a security feature in Linux that prevents the execution of files from a specific directory. When a directory is mounted with the noexec flag, it means that any executable files within that directory cannot be run. This flag is often used to improve system security by preventing malicious scripts or programs from being executed from a specific location.

The Issue with JIRA Installation

During the installation of JIRA Data Center on Linux, the installer attempts to run its internal Java from the /tmp directory. However, since the /tmp directory is mounted as noexec, the installer fails to run the Java executable, resulting in a failed installation.

Workarounds to Overcome the Issue

To overcome the issue of the /tmp directory being mounted as noexec, you can try the following workarounds:

1. Temporarily Mount the /tmp Directory as Executable

You can temporarily mount the /tmp directory as executable using the following command:

sudo mount -o remount,exec /tmp

This will allow the /tmp directory to be executed temporarily, allowing the JIRA installer to run its internal Java.

2. Create a Temporary Directory for the Installer

You can create a temporary directory and mount it as executable using the following command:

sudo mkdir /tmp/installer
sudo mount -o remount,exec /tmp/installer

Then, you can change the directory to /tmp/installer and run the JIRA installer from there:

sudo chdir /tmp/installer
sudo ./jira-install.sh

3. Modify the JIRA Installer to Run from a Different Directory

You can modify the JIRA installer to run from a different directory that is not mounted as noexec. To do this, you can create a symbolic link to the JIRA installer executable in a different directory:

sudo ln -s /path/to/jira/installer/jira-install.sh /tmp/installer

Then, you can run the JIRA installer from the /tmp/installer directory:

sudo chdir /tmp/installer
sudo ./jira-install.sh

4. Modify the /tmp Directory to be Mounted as Executable

If you are the system administrator, you can modify the /tmp directory to be mounted as executable by default. To do this, you can add the following line to the /etc/fstab file:

tmpfs /tmp tmpfs defaults,exec 0 0

Then, you can remount the /tmp directory to apply the changes:

sudo mount -o remount /tmp

Conclusion

In conclusion, the issue of thetmpdirectory being mounted asnoexecduring JIRA Data Center installation on Linux can be overcome by trying the above workarounds. By temporarily mounting the/tmpdirectory as executable, creating a temporary directory for the installer, modifying the JIRA installer to run from a different directory, or modifying the/tmp` directory to be mounted as executable, you can successfully install JIRA Data Center on Linux.

Additional Tips and Considerations

  • Make sure to test the workarounds in a non-production environment before applying them to a production environment.
  • Be aware of the security implications of modifying the /tmp directory to be mounted as executable.
  • Consider creating a separate directory for the JIRA installer and modifying the installer to run from that directory.
  • If you are using a Linux distribution that has a package manager, consider using the package manager to install JIRA Data Center instead of running the installer manually.

Troubleshooting and Support

If you encounter any issues during the installation process, you can refer to the JIRA documentation or contact the JIRA support team for assistance. Additionally, you can try searching online for solutions to specific issues or posting questions on online forums and communities.

Q: What is the noexec flag in Linux, and how does it affect JIRA installation?

A: The noexec flag is a security feature in Linux that prevents the execution of files from a specific directory. When a directory is mounted with the noexec flag, it means that any executable files within that directory cannot be run. During JIRA Data Center installation on Linux, the installer attempts to run its internal Java from the /tmp directory, which is often mounted as noexec for security purposes. This results in a failed installation.

Q: How can I temporarily mount the /tmp directory as executable?

A: You can temporarily mount the /tmp directory as executable using the following command:

sudo mount -o remount,exec /tmp

This will allow the /tmp directory to be executed temporarily, allowing the JIRA installer to run its internal Java.

Q: Can I create a temporary directory for the JIRA installer?

A: Yes, you can create a temporary directory and mount it as executable using the following command:

sudo mkdir /tmp/installer
sudo mount -o remount,exec /tmp/installer

Then, you can change the directory to /tmp/installer and run the JIRA installer from there:

sudo chdir /tmp/installer
sudo ./jira-install.sh

Q: How can I modify the JIRA installer to run from a different directory?

A: You can modify the JIRA installer to run from a different directory that is not mounted as noexec. To do this, you can create a symbolic link to the JIRA installer executable in a different directory:

sudo ln -s /path/to/jira/installer/jira-install.sh /tmp/installer

Then, you can run the JIRA installer from the /tmp/installer directory:

sudo chdir /tmp/installer
sudo ./jira-install.sh

Q: Can I modify the /tmp directory to be mounted as executable?

A: Yes, if you are the system administrator, you can modify the /tmp directory to be mounted as executable by default. To do this, you can add the following line to the /etc/fstab file:

tmpfs /tmp tmpfs defaults,exec 0 0

Then, you can remount the /tmp directory to apply the changes:

sudo mount -o remount /tmp

Q: What are the security implications of modifying the /tmp directory to be mounted as executable?

A: Modifying the /tmp directory to be mounted as executable can have security implications, as it allows executable files to be run from that directory. This can increase the risk of malicious scripts or programs being executed from the /tmp directory.

Q: Can I use a package manager to install JIRA Data Center on Linux?

A: Yes, if you are using a Linux distribution that has a package manager, you can use the package manager to install JIRA Data Center instead of running the installer manually. This can simplify the installation process and reduce the risk of errors.

Q: Where can I find additional information and support for JIRA Data Center installation on Linux?

A: You can refer to the JIRA documentation, online forums and communities, or contact the JIRA support team for additional information and support.
