Installation Considerations

Edge for Private Cloud v. 4.16.05

A typical Edge installation consists of Edge components distributed across multiple nodes. After you install Edge on a node, you then install and configure one or more Edge components on the node.

Installation process

Installing Edge on a node is a multi-step process:

  • Disable SELinux on the node or set it to permissive mode. See Install the Edge apigee-setup utility for more.
  • Select your Edge configuration from the list of recommended topologies. For example, you can install Edge on a single node for testing, or on 13 nodes for production. See Installation Topologies for more.
  • On each node in your selected topology, install the Edge apigee-setup utility:
    • Download the Edge file to /tmp/
    • Install the Edge apigee-service utility and dependencies.
    • Install the Edge apigee-setup utility and dependencies.

      See Install the Edge apigee-setup utility for more.
  • Use the apigee-setup utility to install one or more Edge components on each node based on your selected topology.
    See Install Edge components on a node on a node.
  • On the Management Server node, use the apigee-setup utility to install apigee-provision, the utilities that you use to create and manage Edge organizations.
    See Onboard an organization for more.

Handling an installation failure

In the case of a failure during the installation of an Edge component, you can try to correct the issue, and then run the installer again. The installer is designed to be run repeatedly in cases where it detects a failure, or if you later want to change or update a component after installation.

Configure Postgres master-standby replication

By default, Edge installs all Postgres nodes in master mode. However, in production systems with multiple Postgres nodes, you configure them to use master-standby replication so that if the master node fails, the standby node can continue to server traffic. See Set up Master-Standby Replication for Postgres for more.

Who can perform the install

The Apigee Edge distribution files are installed as a set of RPMs and dependencies. To install, uninstall, and update Edge, the Edge commands must be run by the root user or by a user that has full sudo access. For full sudo access, that means the user has sudo access to perform the same operations as root.

Any user who wants to run the following commands or scripts must either be root, or be a user with full sudo access:

  • apigee-service utility:
    • apigee-service commands: install, uninstall, update.
    • apigee-all commands: install, uninstall, update.
  • script to install Edge components (Unless you have already used "apigee-service install" to install the required RPMs. Then root or full sudo access if not required.)
  • script to update Edge components

Also, the Edge installer creates a new user on your system, named "apigee". Many Edge commands invoke sudo to run as the "apigee" user.

Any user who wants to run all other commands than the ones shown above must be a user with full sudo access to the "apigee" user. These commands include:

  • apigee-service utility commands, including:
    • apigee-service commands such as start, stop, restart, configure.
    • apigee-all commands such as start, stop, restart, configure.

To configure a user to have full sudo access to the "apigee" user, edit the sudoers file to add:

installUser        ALL=(apigee)      NOPASSWD: ALL

where installUser is the username of the person working with Edge.

Any files or resources used by the Edge commands must be accessible to the "apigee" user. This includes the Edge license file and any config files.

When creating a configuration file, you can change its owner to "apigee:apigee" to ensure that it is accessible to Edge commands:

  1. Create the file in an editor as any user.
  2. Chown the owner of the file to "apigee:apigee" or, if you changed the user running the Edge service from the "apigee" user, chown the file to the user who is running the Edge service.

Silent installation of Edge components

You must pass a configuration file to the apigee-setup utility that contains the information about the Edge installation. The only requirement on silent installations is that the configuration file must be accessible or readable by the "apigee" user. For example, put the file in the /tmp directory on the node and chown it to "apigee:apigee".

All information in the configuration file is required except for the Edge system administrator's password. If you omit the password, the apigee-setup utility prompts you to enter it on the command line.

See Install Edge components on a node for more.

Internet or non-Internet installation

To install Edge on a node, the node must be able to access the Apigee repository:

  • Nodes with an external Internet connection

    Nodes with an external internet connection access the Apigee repository to install the Edge RPMs and dependencies.
  • Nodes without an external Internet connection

    Nodes without an external Internet connection can access a mirrored version of the Apigee repository that you set up internally. This repository contains all Edge RPMs, but you have to ensure that you have all other dependencies available from repos on the internal network.

Resolving RPM installation dependencies

The Apigee Edge distribution files are installed as a set of RPM files, each of which can have its own chain of installation dependencies. Many of these dependencies are defined by third-party components that are outside the control of Apigee and can change at any time. Therefore, the documentation does not list the explicit version number of each dependency.

If you are performing an installation on a machine with internet access, the node can download the necessary RPMs and dependencies. However, if you are installing from a node without internet access, you typically set up an internal repo containing all necessary dependencies. The only way to guarantee that all dependencies are included in your local repo is to attempt an installation, identify any missing dependencies, and copy them to the local repo until the installation succeeds.

Setting up a virtual host

A virtual host on Edge defines the domains and Edge Router ports on which an API proxy is exposed, and, by extension, the URL that apps use to access an API proxy. A virtual host also defines whether the API proxy is accessed by using the HTTP protocol, or by the encrypted HTTPS protocol.

As part of the Edge onboarding process, you have to create an organization, environment, and virtual host. Edge provides the setup-org command to make this process easier for new users.

When you create the virtual host, you must specify the following information:

  • The name of the virtual host that you use to reference it in your API proxies.
  • The port on the Router for the virtual host. Typically these ports start at 9001 and increment by one for every new virtual host.
  • The host alias of the virtual host. Typically the DNS name of the virtual host.

The Edge Router compares the Host header of the incoming request to the list of available host aliases as part of determining the API proxy that handles the request. When making a request through a virtual host, either specify a domain name that matches the host alias of a virtual host, or specify the IP address of the Router and the Host header containing the host alias.

For example, if you created a virtual host with a host alias of on port 9001, then a cURL request to an API through that virtual host could use one of the following forms:

  • If you have a DNS entry for

  • If you do not have a DNS entry for

    curl http://<routerIP>:9001/{proxy-base-path}/{resource-path} -H 'Host:'

    In this form, you specify the IP address of the Router, and pass the host alias in the Host header.

    Note: The curl command, most browsers, and many other utilities automatically append the Host header with the domain as part of the request, so you can actually use a curl command in the form:

    curl http://<routerIP>:9001/{proxy-base-path}/{resource-path}

Options when you do not have a DNS entry for the virtual host

One option when you do not have a DNS entry is to set the host alias to the IP address of the Router and port of the virtual host, as <routerIP>:port. For example:

Then you make a curl command in the form below:

curl http://<routerIP>:9001/{proxy-base-path}/{resource-path} 

This option is preferred because it works well with the Edge UI.

If you have multiple Routers, add a host alias for each Router, specifying the IP address of each Router and port of the virtual host.

Alternatively, you can set the host alias to a value, such as Then, you have to pass the Host header on every request:

curl -v http://<routerIP>:9001/{proxy-base-path}/{resource-path}  -H 'host:'

Or, add the host alias to your /etc/hosts file. For example, add this line to /etc/hosts:

Then you can make a request as if you had a DNS entry:

curl -v{proxy-base-path}/{resource-path}

Configuring Edge components post installation

To configure Edge after installation, you use a combination of .properties files and Edge utilities. For example, to configure TLS/SSL on the Edge UI, you edit .properties files to set the necessary properties. Changes to .properties files require you to restart the affected Edge component.

The .properties files are located in the /opt/apigee/customer/application directory. Each component has its own .properties file in that directory. For example, and

To set a property for a component, edit the corresponding .properties file, and then restart the component:

> /opt/apigee/apigee-service/bin/apigee-service component restart

For example:

> /opt/apigee/apigee-service/bin/apigee-service edge-router restart

When you update Edge, the .properties files in the /opt/apigee/customer/application directory are read. That means the update retains any properties that you set on the component.

See How to Configure Edge for more information on Edge configuration.

Ensure Edge Router can access /etc/rc.d/init.d/functions

The Edge Router a BaaS Portal both use the Nginx router and require read access to /etc/rc.d/init.d/functions.

If your security process requires you to set permissions on /etc/rc.d/init.d/functions, do not set them to 700 or else the router will fail to start. Permissions can be set to 744 to allow read access to /etc/rc.d/init.d/functions.

Invoking commands on Edge components

Edge installs management utilities under /opt/apigee/apigee-service/bin that you can use to manage an Edge installation. For example, you can use the apigee-all utility to start, stop, restart, or determine the status of all Edge components on the node:

/opt/apigee/apigee-service/bin/apigee-all stop|start|restart|status|version

Use the apigee-service utility to control and configure individual components. The apigee-service utility has the form:

/opt/apigee/apigee-service/bin/apigee-service component action

For example, to restart the Edge Router:

/opt/apigee/apigee-service/bin/apigee-service edge-router restart

You can determine the list of components installed on the node by examining the /opt/apigee directory. That directory contains a subdirectory for every Edge component installed on the node. Each subdirectory is prefixed by:

  • apigee - a third-party component used by Edge. For example, apigee-cassandra.
  • edge - an Edge component from Apigee. For example, edge-management-server.
  • edge-mint - a Monetization component. For example edge-mint-management-server.
  • baas - an API BaaS component. For example baas-usergrid.

The complete list of actions for a component depends on the component itself, but all components support the following actions:

  • start, stop, restart
  • status, version
  • backup, restore
  • install, uninstall

Accessing log files

The log file for apigee-setup and the script is written to /tmp/setup-root.log.

The log files for each component are contained in the /opt/apigee/var/log directory. Each component has its own subdirectory. For example, the logs for the Management Server are in the directory:


Common Yum commands

The Edge installation tools for Linux rely on Yum to install and update components. You might have to use several Yum commands to manage an installation on a node.

  • Clean all Yum caches:
    sudo yum clean all
  • To update an Edge component:
    sudo yum update componentName
    For example:
    sudo yum update apigee-setup
    sudo yum update edge-management-server

Edge installs all files in the /opt/apigee directory.
