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 servers used by both the web applications and the WAE platform.
An installer is an executable that runs a script to install the MATE and WAE software in the proper locations. Although both MATE and 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.
