Installing Migration Toolkit on a CentOS or RHEL 7 and 8 Host¶

You can use an RPM package to install Migration Toolkit on a CentOS or RHEL host. The following steps provide detailed information about accessing the EnterpriseDB repository and installing Migration Toolkit.

Creating a Repository Configuration File

To create the repository configuration file, assume superuser privileges and invoke the following command:

```
On RHEL or CentOs 7:
```

*  *   yum -y install https://yum.enterprisedb.com/edb-repo-rpms/
*  *   edb-repo-latest.noarch.rpm

```
On RHEL or CentOs 8:
```

*   dnf -y install https://yum.enterprisedb.com/edb-repo-rpms/
*   edb-repo-latest.noarch.rpm

The repository configuration file is named edb.repo. The file resides in /etc/yum.repos.d.

After creating the edb.repo file, use your choice of editor to ensure that the value of the enabled parameter is 1, and replace the username and password placeholders in the baseurl specification with the name and password of a registered EnterpriseDB user.

*   [edb]
*   name=EnterpriseDB RPMs $releasever - $basearch
*   baseurl=https://<username>:<password>@yum.enterprisedb.com/
*   edb/
*   redhat/rhel-$releasever-$basearch
*   enabled=1
*   gpgcheck=1
*   gpgkey=file:///etc/pki/rpm-gpg/ENTERPRISEDB-GPG-KEY

After saving your changes to the configuration file, install the EPEL repository:

```
On RHEL or CentOS 7:
```

*  *   yum -y install https://dl.fedoraproject.org/pub/epel/
*  *   epel-release-latest-7.noarch.rpm

```
On RHEL or Centos 8:
```

*   dnf -y install https://dl.fedoraproject.org/pub/epel/
*   epel-release-latest-8.noarch.rpm

If you are using RHEL or CentOS 8.x, you must enable an additional repository to resolve dependencies:

```
On CentOS 8 (Powertools repo):
```

*   dnf config-manager --set-enabled PowerTools

On RHEL 8 (codeready-builder-for-rhel-8- \* -rpms repo):

*   ARCH=$( /bin/arch )
*   subscription-manager repos --enable "codeready-builder-for
*   -rhel-8-${ARCH}-rpms"

Installing Migration Toolkit

```
On RHEL or CentOs 7:
```

*  *   yum -y install edb-migrationtoolkit

```
On RHEL or CentOs 8:
```

*   dnf -y install edb-migrationtoolkit

When you install an RPM package that is signed by a source that is not recognized by your system, yum may ask for your permission to import the key to your local server. If prompted, and you are satisfied that the packages come from a trustworthy source, enter a y, and press Return to continue.

During the installation, yum may encounter a dependency that it cannot resolve. If it does, it will provide a list of the required dependencies that you must manually resolve.

After installing Migration Toolkit, you must configure the installation. Perform the following steps before invoking Migration Toolkit.

Using Migration Toolkit with IDENT Authentication

By default, the pg_hba.conf file for the RPM installer enforces IDENT authentication for remote clients. Before invoking Migration Toolkit, you must either modify the pg_hba.conf file, changing the authentication method to a form other than IDENT (and restarting the server), or perform the following steps to ensure that an IDENT server is accessible:

Confirm that an identd server is installed and running. You can use the yum package manager to install an identd server by invoking the command:

```
`yum install xinetd authd`
```

The command should create a file named `/etc/xinetd.d/auth` that contains:

*   service auth
*   {
*   disable       = yes
*   socket_type   = stream
*   wait          = no
*   user          = ident
*   cps           = 4096 10
*   instances     = UNLIMITED
*   server        = /usr/sbin/in.authd
*   server_args   = -t60 --xerror --os
*   }

!!! Note

If the file includes a `-E` argument at the end of `server_args`, please erase the `-E`.

Then, to start the identd server, invoke the commands:

*   systemctl enable xinetd
*   systemctl start xinetd

Open the pg_ident.conf file and create a user mapping:

*   # map_name system_username postgres_username
*   edbas enterprisedb enterprisedb

Where:
- The name specified in the map_name column is a user-defined name that will identify the mapping in the pg_hba.conf file. - The name specified in the system_username column is enterprisedb. - The name specified in the postgres_username column is enterprisedb.

Open the pg_hba.conf file and modify the IDENT entries.

On an IPv4 host:
host all all 127.0.0.0/0 ident map=edbas
On an IPv6 host:
host all all ::1/128 ident map=edbas

Restart the EDB Postgres Advanced Server service before invoking Migration Toolkit.

Upgrading an RPM Installation¶

If you have an existing RPM installation, you can use yum to upgrade your repository configuration file and update to a more recent product version. To update the edb.repo file, assume superuser privileges and enter:

yum upgrade edb-repo

yum will update the edb.repo file to enable access to the current EnterpriseDB repository, configured to connect with the credentials specified in your edb.repo file. Then, you can use yum to upgrade Migration toolkit:

yum upgrade edb-migrationtoolkit

Installing Migration Toolkit on a CentOS, or RHEL 7 ppc64le Host¶

You can use an RPM package to install Migration Toolkit on a CentOS or RHEL ppc64le host.

Before installing Migration toolkit , you must:

Create the Advance Toolchain repository configuration file; assume superuser privileges and invoke the following command:

*   rpm --import https://public.dhe.ibm.com/software/server/POWER/
*   Linux/toolchain/at/redhat/RHEL7/gpg-pubkey-6976a827-5164221b

After creating the advance-toolchain.repo file, use your choice of editor to ensure that the value of the enabled parameter is 1, and replace the username and password placeholders in the baseurl specification with the name and password of a registered EnterpriseDB user.

*   [advance-toolchain]
*   name=Advance Toolchain IBM FTP
*   baseurl=https://public.dhe.ibm.com/software/server/POWER/
*   Linux/toolchain/at/redhat/RHEL7
*   failovermethod=priority
*   enabled=1
*   gpgcheck=1
*   gpgkey=ftp://public.dhe.ibm.com/software/server/POWER/Linux/
*   toolchain/at/redhat/RHELX/gpg-pubkey-6976a827-5164221b

The following steps provide detailed information about accessing the EnterpriseDB repository and installing Migration Toolkit.

Creating a Repository Configuration File

To create the EDB repository configuration file, assume superuser privileges and invoke the following command:

*  *   yum -y install https://yum.enterprisedb.com/edb-repo-rpms/
*  *   edb-repo-latest.noarch.rpm

The repository configuration file is named edb.repo. The file resides in /etc/yum.repos.d.

After creating the edb.repo file, use your choice of editor to ensure that the value of the enabled parameter is 1, and replace the username and password placeholders in the baseurl specification with the name and password of a registered EnterpriseDB user.

*   [edb]
*   name=EnterpriseDB RPMs $releasever - $basearch
*   baseurl=https://<username>:<password>@yum.enterprisedb.com/edb/
*   redhat/rhel-$releasever-$basearch
*   enabled=1
*   gpgcheck=1
*   gpgkey=file:///etc/pki/rpm-gpg/ENTERPRISEDB-GPG-KEY

After saving your changes to the configuration file, install the EPEL package:

*  *   yum -y install https://dl.fedoraproject.org/pub/epel/
*  *   epel-release-latest-7.noarch.rpm

If you are using RHEL 7 ppc64le, you must enable an additional repository to resolve dependencies:

*   subscription-manager repos --enable "rhel-*-optional-rpms"
*   --enable "rhel-*-extras-rpms"  --enable "rhel-ha-for-rhel-*
*   -server-rpms"

To install Migration Toolkit, run the following command.

*  *   yum -y install edb-migrationtoolkit

Installing Migration Toolkit on a Debian or Ubuntu Host¶

To install a package with apt, complete the following steps. When invoking the commands, replace the username and password with the user credentials provided by EnterpriseDB.

Assume superuser privileges:

*   sudo su –

Configure the EnterpriseDB repository:

- On Debian 9, perform the following step to configure the EnterpriseDB repository:

*       sh -c 'echo "deb https://username:password@apt.
*       enterprisedb.com/$(lsb_release -cs)-edb/ $(lsb_release
*       -cs) main" > /etc/apt/sources.list.d/edb-$(lsb_release
*       -cs).list'

- On Debian 10, perform the following steps to configure the EnterpriseDB repository:

a.  Set up the EnterpriseDB repository:

*       sh -c 'echo "deb [arch=amd64] https://
*       apt.enterprisedb.com/
*       $(lsb_release -cs)-edb/ $(lsb_release -cs) main"
*       > /etc/
*       apt/sources.list.d/edb-$(lsb_release -cs).list'

b.  Substitute your EnterpriseDB credentials for the `username` and `password` placeholders in the following command:

*       sh -c 'echo "machine apt.enterprisedb.com login <username>
*       password <password>" > /etc/apt/auth.conf.d/edb.conf'

c.  Add support to your system for secure APT repositories:

*       apt-get install apt-transport-https

```
d. Add the EBD signing key:
```

*       wget -q -O - https://username:password
*       @apt.enterprisedb.com/edb-deb.gpg.key | apt-key add -

```
e. Update the repository metadata:
```

*       apt-get update

f. Install the `edb-migrationtoolkit` package:

*       apt-get -y install edb-migrationtoolkit

Installing Migration Toolkit on a SLES Host¶

You can use the zypper package manager to install a Migration toolkit on an SLES 12 host. zypper will attempt to satisfy package dependencies as it installs a package, but requires access to specific repositories that are not hosted at EnterpriseDB.

You must assume superuser privileges and stop any firewalls before installing Migration Toolkit. Then, use the following commands to add EnterpriseDB repositories to your system:

*   zypper addrepo https://zypp.enterprisedb.com/suse/
*   edb-sles.repo

The command creates the repository configuration files in the /etc/zypp/repos.d directory. Use the following command to refresh the metadata on your SLES host to include the EnterpriseDB repository:

*  *   zypper refresh

When prompted, provide credentials for the repository; specify a to always trust the provided key and update the metadata to include the EnterpriseDB repository.

You must also add SUSEConnect and the SUSE Package Hub extension to the SLES host, and register the host with SUSE, allowing access to SUSE repositories. Use the commands:

*   SUSEConnect -r 'REGISTRATION_CODE' -e 'EMAIL'
*    SUSEConnect -p PackageHub/12.4/x86_64
*    SUSEConnect -p sle-sdk/12.4/x86_64

Install SUSEConnect to register the host with SUSE, allowing access to SUSE repositories:

*   zypper addrepo https://download.opensuse.org/repositories/
*   Apache:/Modules/SLE_12_SP4/Apache:Modules.repo

Use the following command to refresh the metadata:

*  *   zypper refresh

Install OpenJDK (version 1.8) for Java based components:

*   zypper -n install java-1_8_0-openjdk

Now you can use the zypper utility to install a Migration Toolkit:

*   zypper -n install edb-migrationtoolkit
