You can remove Apigee mTLS at any time. This section describes how to remove it and to verify
that it has been removed.

**To roll back the Apigee mTLS installation:**

1. Log in to a node in your cluster. The order in which you do this does not matter.
2. Stop all components on the node, as the following example shows:

   ```
   /opt/apigee/apigee-service/bin/apigee-all stop
   ```
3. Uninstall the `apigee-mtls` service by executing the following command:

   ```
   /opt/apigee/apigee-service/bin/apigee-service apigee-mtls uninstall
   ```
4. Start all components on the node in the [start order](https://docs.apigee.com/private-cloud/v4.51.00/starting-stopping-and-restarting-apigee-edge#start-order), as the following example shows:

   ```
   /opt/apigee/apigee-service/bin/apigee-service component_name start
   ```
5. Repeat this process for each node in the cluster.

**To verify that the uninstallation was successful, you can do the following (in any
order):**

1. On each node that is running ZooKeeper, check that the Consul services are not in the `/usr/lib/systemd/system` directory:
   1. Change to the `/usr/lib/systemd/system` directory:

      ```
      cd /usr/lib/systemd/system
      ```
   2. Ensure that the following files are not in that directory:
      - `consul_egress.service`
      - `consul_server.service`
   3. If either of these files is in the `/usr/lib/systemd/system` directory, delete it.
2. On each node that is running ZooKeeper, check to see if the `apigee-mtls` and `apigee-mtls-consul` directories exist:
   1. Change to the Apigee root directory:

      ```
      cd ${APIGEE_ROOT:-/opt/apigee}
      ```
   2. Check the contents of the directory:

      ```
      ls
      ```
   3. Ensure that the following directories do *not* exist in this directory:
      - `apigee-mtls-version`
      - `apigee-mtls-consul-version`
   4. If either of these directories exist, delete them.
3. In the same directory, ensure that symlinks to the following have been removed:
   - `apigee-mtls`
   - `apigee-mtls-consul`

   To do this, use the find `-L` option, as the following example shows:

   ```
   find -L ./
   ```

   If symbolic links to these directories remain, you can remove them with either the
   `rm` or `unlink` commands.
4. On each node that is running ZooKeeper, check that Consul has been removed by using the `which` command:

   ```
   which consul
   ```

   This command should respond with a message similar to the following:

   ```
   "/usr/bin/which: no consul in (...:/opt/apigee/apigee-adminapi-version/bin:...)"
   ```
5. Execute the following command as root or with sudo:

   ```
   iptables -t nat -L OUTPUT
   ```

   This command should display column headings but no data in the columns, as the following example
   shows:

   ```
   target     prot opt source               destination   
   ```
6. Use `yum` to determine if the Apigee mTLS packages are installed:

   ```
   yum list installed
   ```

   This command should *not* display any packages matching the following:
   - `apigee-mtls-version`
   - `apigee-mtls-consul-version`
