This chapter takes you deeper into the relationships between processes, the kernel, and system resources. There are three basic kinds of hardware resources: CPU, memory, and I/O. Processes vie for these resources, and the kernel’s job is to allocate resources fairly. The kernel itself is al...
One of the simplest ways to check your system’s memory status as a whole is to run the free command or view /proc/meminfo to see how much real memory is being used for caches and buffers. As we’ve just mentioned, performance problems can arise from memory shortages. If there isn’t...
You can view your system’s partition table with parted -l. Here is sample output from two disk devices with two different kinds of partition tables: 您可以使用parted -l命令查看系统的分区表。 下面是两个不同类型分区表的两个磁盘设备的示例输出: 代码语言:javascript 复制 # parted -l Model: ATA...

Namespaces are a kernel feature that allow a virtual view of isolated system resources. By isolating a process from system resources, you can specify and control what a process is able to interact with. Namespaces are an essential part of Control Groups. namespaces [jizg@rhel8 ~]$ ls /proc...
