Dbrookie First day of study

The last night just moved home panda eyes rushed to the classroom, and then is slashing Linux system, the teacher really has spoken very clearly, strange only brains have pigs ah! As a one-day learning of Linux system rookie, even when the column editor I can not write the professional blog, can only share some of the simple concept of understanding, but also hope that whether it is with the eye of the eye or lipstick on the cattle people, do not laugh at it.

Unix/linux Core idea: All documents

1. Install the operating system: In addition to more practice more than may not have a good way to learn, the steps are similar, but need to compare different versions of the difference and then learn, the specific each is what to do, although not each can say up, but learn to learn the meticulous learning it, a mouthful can not eat fat.

2. Mount: The system has only one root directory, is a tree structure, so it is necessary to mount the directory under the root directory, can be effectively found, the files under the mounted directory can not be seen, only to see the files in the mounted directory.

3. LVM PV, VG, LV: In order to avoid "eating" and "not enough to eat", in addition to the boot program's boot standard partition, and other already divided areas, the remaining areas are processed into the PV physical volume (cannot store files, immutable), and then their resources logically integrated into the VG (dynamic variable), It is logically divided into LV logical volume according to the requirement.

Other I can only sense can not be said, also do not fraught, although to today's heart is still broken, but because will never allow themselves in the difficulties in front of retreat, this is the same, forcing himself a bar, no one, blame fear, first write this.
