The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

This chapter provides an overview of what happens as a result of the installation process, such as which packages are installed and how environment variables are set. This guide explains how to install the server software used by both the web applications and the Cisco WAN Automation Engine (WAE) platform.
An installer is an executable that runs a script to install the WAE software in the proper locations. Although WAE features are installed, they are active only if you have a license for them.
The installer automates the installation process by asking you a series of questions and performing the following tasks.
– Whether the device has the appropriate system requirements, including proper operating system, disk space, total memory, and required software packages.
If the installer sees that you do not have the appropriate system requirements, it either exits, gives a warning, or prompts you whether to continue. Since the installer might be checking for more than what your specific requirements are, you can press “y” to attempt to continue.
– Whether there are existing package installations; if there are, they are preserved
– /etc/sysctl.conf file
Sets fs.file-max=512000 if it is less than 65535.
– /etc/security/limits.conf
Sets nofile to 65535 for the WAE username.
– /etc/security/limits.d/90-nproc.conf
Sets nproc to 8192 for the WAE username.
$CARIDEN_HOME/lib/ext/pmacct/sbin
, which enables you to collect flow data using flow_manage
and flow_get
without having to change the file capabilities for the flow collection server. This is the equivalent of executing the following command: setcap 'cap_net_bind_service=+ep' $CARIDEN_HOME/lib/ext/pmacct/sbin/*
wae-web-server
), WAE Network Interface (NI) server ( wae-ni
) (if applicable), and all System services ( wae-svcs-*
). For detailed information on services, including how to start, stop, restart, and check their status, see the Cisco WAE System Administration Guide. – For executables, the WAE user has read, write, and execute permissions. Users listed in /etc/group
have read and execute permissions. All others have read-only permissions.
– For non-executables, only the WAE user has read and write permissions. All other users have read-only permissions.
The jdk-7u60
package is installed in /usr/java/latest
. All other RPM packages are installed in /opt/cariden/software
. To list these packages, enter this command:
Note Table 5-1 in “WAE Planning Software Installation,” lists the services and packages that are installed on each server.
The current symbolic link for the DLC package is /opt/cariden/software/mate/current.
Example RPM name: wae-dlc-1.0.2-123456789
Corresponding current link name: /opt/cariden/software/mate/current
Other than the DLC package, all other packages have a current symbolic link using the package name as the link name.
To determine the release version, enter the following command:
To determine the current RPM versions, enter the following command:
Upon logging out and back in as the WAE user after an installation, the environment variables are automatically set using.sh scripts in /etc/profile.d
directory.
