Optionally we can also create a symlink for easier access – this way we don’t need to remember the exact version: # ln -s /opt/redmine-4.0.3 /opt/redmine We’ll switch to this directory, and extract the archive: # cd /opt From here we can download the compressed tarball with wget to the target system:Īs the above command suggests, we’ll install the application under the /opt directory. To obtain the application, visit the the official download site (which is running on Redmine).# dnf install kernel-devel kernel-headers gcc postgresql-devel ruby ruby-devel rubygems To install the packages the operating system will provide, we’ll use dnf:.With the above configuration in place, all we need to do is add the redmine user to the wheel group: # usermod -a -G wheel redmine The second line with the NOPASSWD option is commented out, which will suit our needs. To check that this group is set up as sudoer, we can grep the /etc/sudoers file: # grep "%wheel" /etc/sudoers On RHEL based distributions, there is a wheel user group, who is allowed to use sudo to run privileged commands. We have to set a password for the new user, which we will use when using sudo: # passwd redmine We can revoke this access once the installation is complete. We’ll create a user who will be the owner of the application, and we’ll give it temporary sudo access.If the database setup is new, don’t forget to complete the initdb step in the mentioned guide, or the startup of the database will fail. You can refer to the PostgreSQL installation guide on RHEL8 for the detailed setup of the database in general, in this article we’ll cover only the steps needed for Redmine. We’ll use the Red Hat repositories available after enabling subscription management to solve the operating system dependencies. For the installation we’ll have to use rubygems and bundler, and compile a lot of dependencies, so it will take a while. How to install redmine on Redhat 8 step by step instructions $ – requires given linux commands to be executed as a regular non-privileged user # – requires given linux commands to be executed with root privileges either directly as a root user or by use of sudo command Privileged access to your Linux system as root or via the sudo command.
