First, disk partition

• Definition: partition using a disk editor (partition editor) several logical partitioning portion on the disk. Once the disc is divided into a plurality of partitions (Partition), different types of directories and files can be stored into different partitions.
• Two kinds of partition table form:
  • MBR partition table: maximum support 2.1TB hard drive, supports up to four partitions;
  • GPT partition table (globally unique identifier partition table): GPS support 9.4ZB hard disk (1ZB = 1024PB, 1PB = 1024EB, 1EB = 1024TB), supported by the theoretical number of partitions is not limited, but a Windows limitation of 128 primary partitions.
• Partition type:
  • Primary partition: You can only have up to four;
  • Extended partition:
    • At most one;

  • / Dev / sda1 (SCSI hard disk interface, SATA hard disk interface)

Fourth, the mount

• You must be partitioned
  • You must be partitioned
    • / (Root partition)
    • swap partition (swap)
      • If real memory is less than 4GB, swap twice the memory;
      • If real memory is larger than 4GB, swap and memory consistency;
  • Recommended Partition
    • / Boot (boot partition, CentOS6 lowest 200M, CentOS7 minimum 1GB)
  • Frequent Partitions
    • / Home (for file servers)
    • / Www (for Web servers)

5, configuration IP address

• Command line, enter Setup (only in CentOS6 available), select Network conf iguration , and then select Device conf iguration , enter eth0 card, find On boot is selected, click on the OK  , and then click  the Save , then click the Save & the Quit , then click the Quit , then in command line input Service Network restart .
