Customize Install Directories

When you install Redis Enterprise Software on Red Hat Enterprise Linux, you can customize the installation directories.

The files are installed in the redislabs directory located in the path that you specify.

Considerations

• When you install with custom directories, the installation does not run as an RPM file.

• If a redislabs directory already exists in the path that you specify, the installation fails.

• All nodes in a cluster must be installed with the same file locations.

• Custom installation directories are not supported for databases using Auto Tiering.

• Configure different mount points for data and log directories.

Specify file locations

You can specify these file locations:

These files are not in the custom directories:

• OS files

  • /etc/cron.d/redislabs
  • /etc/firewalld/services
  • /etc/firewalld/services/redislabs-clients.xml
  • /etc/firewalld/services/redislabs.xml
  • /etc/ld.so.conf.d/redislabs_ldconfig.conf.tmpl
  • /etc/logrotate.d/redislabs
  • /etc/profile.d/redislabs_env.sh
  • /usr/lib/systemd/system/rlec_supervisor.service.tmpl
  • /usr/share/selinux/mls/redislabs.pp
  • /usr/share/selinux/targeted/redislabs.pp

• Installation reference files

  • /etc/opt/redislabs/redislabs_custom_install_version
  • /etc/opt/redislabs/redislabs_env_config.sh

To specify directories during [installation]({{< relref "/operate/rs/7.8/installing-upgrading/install/install-on-linux" >}}), include installer flags as [command-line options]({{< relref "/operate/rs/7.8/installing-upgrading/install/install-script" >}}) when you run the install.sh script. For example:

sudo ./install.sh --install-dir <path> --config-dir <path> --var-dir <path>

Configure different mount points for data and log directories {#config-diff-data-log-dirs}

To configure different mount points for data and log directories, use symbolic links:

1. Create a symbolic link for the data directory:

   shCopy

   ln -s /var/opt/redislabs/data </path/to/data/mount/point>
   

2. Create a symbolic link for the log directory:

   shCopy

   ln -s /var/opt/redislabs/log </path/to/log/mount/point>
   

Limitations

Several Redis Enterprise Software installation reference files are installed to the directory /etc/opt/redislabs/ even if you use custom installation directories.

As a workaround to install Redis Enterprise Software without using any root directories, do the following before installing Redis Enterprise Software:

1. Create all custom, non-root directories you want to use with Redis Enterprise Software.

2. Mount /etc/opt/redislabs to one of the custom, non-root directories.
