### VM Ubuntu 18.04 Setup and Configuration For setting up an Ubuntu 18.04 virtual machine (VM), the process involves several key steps to ensure a smooth installation and configuration. #### Preparing the Virtual Machine Environment To begin with, choose a suitable hypervisor such as VMware or VirtualBox. After installing the chosen hypervisor on the host system, create a new virtual machine specifying that it will use an ISO image of Ubuntu 18.04 LTS for its operating system[^3]. #### Installing Ubuntu 18.04 in the VM During the installation phase within the newly created VM environment, follow the prompts provided by the Ubuntu installer. Select language preferences, keyboard layout, and network settings according to personal requirements. When asked about updates during installation, opting for minimal installations can reduce initial setup time but may require additional package installations post-installation using commands like `sudo apt-get update` followed by `sudo apt-get upgrade`. #### Post-Installation Configuration After completing the basic OS installation: - Update existing packages via terminal command `sudo apt-get update && sudo apt-get dist-upgrade`. - Install necessary tools including CA certificates, cURL utility, GNUPG encryption software, and LSB release information which are essential components often required for further configurations or applications setups through executing `sudo apt-get install ca-certificates curl gnupg lsb-release`[^4]. - For kernel development purposes or specific hardware support needs, consider installing corresponding headers files related to your current running kernel version. This step is crucial especially when intending to compile custom drivers or modules against this particular distribution's kernel source tree. - If planning to modify boot loader entries manually later on, familiarize oneself with editing `/etc/default/grub`, where default boot entry could be specified under variable `GRUB_DEFAULT`. Remember after any changes made here, always run `sudo update-grub` so they take effect upon next reboot[^1]. #### Running Services in Background In scenarios requiring certain services to operate continuously without blocking terminals, appending `&` at the end of service start commands allows them to execute asynchronously. Take Redis server startup script located typically inside `/usr/local/redis/bin/` directory paired alongside its configuration file path argument as an example shown below: ```bash /usr/local/redis/bin/redis-server & /usr/local/redis/conf/redis.conf & ``` This approach ensures both immediate execution while also freeing up shell sessions immediately afterwards[^2].
