    The secret of Linux user disk quota: Preventing from occupying the mountain to ensure the stability of the system
    Understand Linux user disk quotas. In the Linux operating system environment, disk quotas are particularly critical as a management strategy, which helps to strengthen the management of users' hard disk storage permissions. Using quota settings, we can reasonably allocate the disk capacity range available to each user or user group to prevent a very small number of users from excessively occupying space and negatively affecting other users. Next, Linux user disk quota. This article mainly explains the implementation plan of Linux user disk quota. Linux view port occupancy covers all aspects of quota setting, maintenance and monitoring. It also prepares some problems that may be encountered in practice. Challenges and solutions. Why do you need to set disk quotas? Setting disk quotas can prevent a certain user or intruder from entering.

  • Two commands to create swap partition
    Two commands to create swap partition
    The swap partition is used to hold the contents of physical memory (RAM) when it fills up. When RAM is exhausted, Linux will move inactive pages in memory to swap space, thereby freeing up memory for system use. Nonetheless, swap space should not be considered a substitute for physical memory. In most cases, it is recommended that the size of swap memory be 1 to 2 times the size of physical memory. In other words, if you have 8GB of memory, the swap space size should be between 8-16GB. If there is no swap partition configured in the system, when the memory is exhausted, the system may kill running processes/applications, causing the system to crash. In this article, we will learn how to add a swap partition to a Linux system. We have two methods: use the fdisk command
