Edge for Private Cloud v. 4.16.09
The checklist covers the preceding prerequisites and provides a list of required files to obtain before proceeding. Here is a summary of the primary requirements covered there.
- Edge system administrator credentials: As part of the installation, you
are prompted to specify an email address and password used to create the Edge system
administrator account. Never use these credentials for anything other than Edge system
administration. You can later create different users and user types to create and manage API
proxies, apps, and all other user-level tasks.
To change the administrator password do not use the Edge UI to change the administrator password. See Resetting Edge Passwords for more information. - OS: For operating system requirements, see https://apigee.com/docs/api-services/reference/supported-software.
- Java: Java requirements are covered under Prerequisites above. Refer to
https://apigee.com/docs/api-services/reference/supported-software.
Ensure that JAVA_HOME points to the root of the JDK for the user performing the installation. - Firewalls: Firewall/host requirements are covered under Prerequisites above. See Installation Requirements before proceeding.
- TCP Wrappers: TCP Wrappers can block communication of some ports and can affect OpenLDAP, Postgres, and Cassandra installation. On those nodes, check /etc/hosts.allow and /etc/hosts.deny to ensure that there are no port restrictions on the required OpenLDAP, Postgres, and Cassandra ports.
- SELinux: Depending on your settings for SELinux, Edge can encounter issues with installing and starting Edge components. If necessary, you can disable SELinux or set it to permissive mode during installation, and then re-enabling it after installation. See Install the Edge apigee-setup utility for more.
-
iptables: Validate that there are no iptables policies preventing
connectivity between nodes on the required Edge ports. If necessary, you can stop iptables
during installation using the command:
> sudo /etc/init.d/iptables stop
On CentOS 7.x:> systemctl stop firewalld - License file: A valid license file must be obtained to install Apigee Edge. Licensing information is covered under Prerequisites above. Refer to Installation Requirements before proceeding.
- Distribution files: The Apigee Edge distribution files are installed as a set of RPMs and dependencies.
-
System limits:
- On Cassandra nodes, set soft and hard memlock, nofile, and address space (as) limits
for installation user (default is “apigee") in /etc/security/limits.conf as shown
below:
apigee soft memlock unlimited
apigee hard memlock unlimited
apigee soft nofile 32768
apigee hard nofile 65536
apigee soft as unlimited
apigee hard as unlimited - On Message Processor nodes, set the maximum number of open file descriptors to 64K by
using the command:
> ulimit -n 65535
If necessary, you can raise that limit. For example, if you have a large number of temporary files open at any one time.
- On Cassandra nodes, set soft and hard memlock, nofile, and address space (as) limits
for installation user (default is “apigee") in /etc/security/limits.conf as shown
below:

Disable DNS lookup on IPv6 when using NSCD
If you have installed and enabled NSCD (Name Service Cache Daemon) you might notice that Message Processors make two DNS lookups: one for IPv4 and one for IPv6.
To disable the DNS lookup on IPv6:- On every Message Processor node, edit /etc/nscd.conf.
- Set the following property:
enable-cache hosts no
