1, what is Linux? To be exact, the Linux kernel (the core program of the system), whose kernel copyright belongs to Linus Torvalds, is issued under the GPL (GNU general public License) Copyright Agreement, and anyone can copy (copy) and modify ( Change), package distribution (distribute), sales, but can not add any restrictions at the time of distribution, and all the original code must be public, so anyone

Disk I/O monitoring is a very important part of unix/linux system management. It can monitor the throughput, the number of I/O per second, disk utilization, service time and other information, and when the exception is found, send alarm information to the system administrator, so that the system administrator to adjust the data layout and other management activities to optimize the overall system performance.Commands that monitor disk I/O for differen

Related background: Why and whatIn recent years, Linux system has been widely concerned and applied by computer industry because of its excellent performance and stability, the flexibility and expansibility of open Source feature, and the lower cost. But in terms of security, the Linux kernel only provides

Create a small Linux with network functions First, copy the required basic network commands to a Linux instance.Copy Ping and ifconfigTo add a network function, you must be driven by the NIC. The NIC Driver is pcnet32.However, pcnet32 has a dependency module that is MII, and MII has no dependency module,So we only need to copy the two modules to ourIn Linux, chec

Better run a few more times!7, the customary shutdown command: ShutdownIn addition, it should be noted that the time of the number of instructions must be increased, otherwise shutdown will jump to Run-level 1 (that is, the single-player maintenance of the login), so it is nerve-racking! Here are some examples of how many time references are available:Reboot, Shutdown: reboot, Halt,poweroff8. Swi

Compile the linux0.00 kernel (full Linux Kernel Analysis-based on the 0.12 kernel) I have bought a fully-analyzed Linux kernel written by Zhao Ke-based on the 0.12 kernel. It seems that the principles of the first four chapters have never had the courage to practice them by myself. Recently, I have made up my mind to take a good look at this book, and I plan to write some study notes to record some gains an

However, if you encounter a kill command exception, you can specify the/bin/kill command explicitly.

There are two mechanisms in Linux: one is the old SystemVinitialization, which comes from Unix and is still used by various Linuxdistros; the other is the Upstart mechanism proposed in recent years. Refer to: http: wwwcnblogscomcassvinarchive2011122. There are two mechanisms in Linux: one is the old-style System V initialization, which is derived from Unix and is still used by various

After this period of time to learn, I also have a certain understanding of Linux, today this blog on the previous knowledge of a summary it.The previous Linux learning blog, from the top down is learning in-depth process, my blog link is as follows:First: Analysis of the Linux operating system how the computer starts and how it operatesChapter Two: Analysis of

interface after startup problems, I would like to tell them: pull down, or use the graphical interface. For a server system that does not have a graphical interface, be honest with SSH remote connection. Why are there so many different distributions? It's all Linux, so why install so many distributions? That's because the system and the system are not the same. Different genres of distribution, the same genre of the distribution, the old system and
