Prerequisites
System Requirements
The host system must meet the following requirements:
- CPU: Armv8 architecture
- RAM: 512 MB or above
- Drive space: The default installation path is /opt/exagear. Ensure that the available space of a drive where the directory is located meets the following requirements:
- 600 MB of free space for the x86 system library and basic file system provided in the ExaGear installation package.
- The x86 applications run by users require extra space to store files such as dependency library file and related system configuration files.
- OS: 64-bit Linux OS (CentOS or Ubuntu), which requires virtual addresses to be at least 48 bits long.
To enable dynamic secondary optimization, the following requirements must be met:
- CPU: The Armv8.2 architecture supports and enables the statistical profiling extension (SPE) function.
- Linux kernel version 4.16 or later.
User Permission Check
Ensure that you have obtained the sudo permission or the root user permission required for performing subsequent operations.
Creating a System User
When the ExaGear release package is installed, the system user exagearopt whose UID is less than 1000 and the system user group exagearopt whose GID is less than 1000 are created, and the login shell is /sbin/nologin. The system user is not allowed to log in to the system.
