Linux installation steps and detailed illustrations that need attention during installation

There is time today I give users a brief introduction of the installation process of CentOS, because recently friends want me to ask this question, the following I explain to you, I use the environment is VMware virtualized environment, operating system is CentOS7.2, the following is the detailed process of installation.

1, a new virtual machine, I believe everyone this will.

650) this.width=650; "src=" Http://s2.51cto.com/wyfs02/M01/7D/11/wKiom1bfrbnBEpsvAALlaOCvXYY521.png "title=" 101_ Look at the picture king. png "alt=" Wkiom1bfrbnbepsvaallaocvxyy521.png "/>

2, this step I choose is a custom installation

3. Select the type of virtual machine compatibility (direct next step)

4, because of the habit I generally choose to install the operating system later

650) this.width=650; "src=" Http://s2.51cto.com/wyfs02/M02/7D/11/wKioL1bftJzioutaAAMJ028vBlQ066.png "title=" 104_ Look at the picture king. png "alt=" Wkiol1bftjzioutaaamj028vblq066.png "/>

5, select the operating system type (This step we choose CentOS64 bit)

650) this.width=650; "src=" Http://s2.51cto.com/wyfs02/M02/7D/13/wKiom1bftayzmjK6AAMac0t8c5M963.png "title=" 105_ Look at the picture king. png "alt=" Wkiom1bftayzmjk6aamac0t8c5m963.png "/>

6, virtual naming and installation of the location

650) this.width=650; "src=" Http://s5.51cto.com/wyfs02/M01/7D/13/wKiom1bfunWQeBQaAALxlD7jrDo262.png "title=" 106_ Look at the picture king. png "alt=" Wkiom1bfunwqebqaaalxld7jrdo262.png "/>

7, CPU processor configuration, because my computer is dual core, so the core number is selected as 2. (This item can be modified later)

650) this.width=650; "src=" Http://s4.51cto.com/wyfs02/M00/7D/13/wKiom1bfuxSBBJJsAAL4mP_Nd-Q149.png "title=" 107_ Look at the picture king. png "alt=" Wkiom1bfuxsbbjjsaal4mp_nd-q149.png "/>

8, the memory configuration, here I choose is a G. (This one can also be changed later)

650) this.width=650; "src=" Http://s5.51cto.com/wyfs02/M00/7D/13/wKiom1bfvAqROuGLAAMbkSdg2pE908.png "title=" 108_ Look at the picture king. png "alt=" Wkiom1bfvaqrouglaambksdg2pe908.png "/>

9, this step is the network access type configuration, respectively, is bridged, NAT, only host mode, not applicable network connection The following are four modes detailed description:

Bridging mode: (bridged mode) This mode is similar to a separate host in the LAN, you need to configure the IP address and subnet mask and need and physical machine (host) in a network segment, so as to communicate with the physical machine, in order to achieve access routing and Internet.

Nat Mode: (Can share the physical machine's IP) This mode, no need to set the IP and subnet mask and so on, can directly through the physical computer network, as long as the physical function of the Internet, virtual machine system can be online, in the creation of virtual machine system, is generally the default this mode, this is its biggest advantage, convenient!

         host Mode: (HOST-ONLY) The real environment and the virtual environment is isolated, it is equivalent to a small LAN!

Do not use a network connection I don't have to say it, ^_^.

10. Selection of I/O bus type (direct next step)

650) this.width=650; "src=" Http://s1.51cto.com/wyfs02/M01/7D/12/wKioL1bfv5Pw-CvrAAMPyvHj4z4445.png "title=" 110_ Look at the picture king. png "alt=" Wkiol1bfv5pw-cvraampyvhj4z4445.png "/>

11, the choice of virtual disk (direct next)

650) this.width=650; "src=" Http://s3.51cto.com/wyfs02/M02/7D/13/wKioL1bfxo7iyqb8AAMD0sTY3LM918.png "title=" 111_ Look at the picture king. png "alt=" Wkiol1bfxo7iyqb8aamd0sty3lm918.png "/>

12, Disk size settings

650) this.width=650; "src=" Http://s4.51cto.com/wyfs02/M01/7D/16/wKiom1bfyc2Bm1C1AALxGaCBj6U399.png "title=" 113_ Look at the picture king. png "alt=" Wkiom1bfyc2bm1c1aalxgacbj6u399.png "/>

13. Now that the virtual machine has been created, we can right-click on the virtual machine and select Settings in the popup menu.

650) this.width=650; "src=" Http://s5.51cto.com/wyfs02/M01/7D/15/wKiom1bfyCCzcsMfAAJZaTgnEAQ042.png "title=" 114_ Look at the picture king. png "alt=" Wkiom1bfycczcsmfaajzatgneaq042.png "/>

14, in the Setup interface, we choose the optical drive, and select the ISO image file we downloaded from the CentOS official website, do the above steps we restart the virtual machine.

650) this.width=650; "src=" Http://s3.51cto.com/wyfs02/M02/7D/14/wKioL1bfyTDxff_gAAJBs7INh8E959.png "title=" 115_ Look at the picture king. png "alt=" Wkiol1bfytdxff_gaajbs7inh8e959.png "/>

15, the following interface the first item means to install directly, the second meaning test this disc whether there is a problem, if there is no problem to start the installation, the third is generally used in the system problems (and WinPE function similar). Because there is no problem with our ISO file, choose the first item directly (Install CentOS 7).

16, i18n internationalization/Localization language choice, we directly next, these after the installation of the system can be set up inside the system.

17, the choice of the toolkit, I choose here is the minimum installation, the following all environments can enter the system, through the Yum Groupinstall installation deployment, because I generally want to learn more problems to find more in-depth understanding, so generally choose the smallest installation is only select minimal Install this option. But in actual work, I usually install the compatibility libraries and development tools in the process of server deployment, so that there will be fewer problems when compiling and installing Tarball. If you want to work with CentOS, you can also choose the server with GUI environment. Hehe, how to install the need to see everyone's needs, here I do not say much.

18, the following four pictures is the disk partition information, I used the custom partitioning method, where the boot partition I gave 200MB because the boot partition is mainly to store bootloader (CentOS7 later with the GRUB2) and some boot need files, not much space. Swap swap partition gives 1024MB (that is, 1G of space) if you later compile the kernel is not enough to use this also to increase through LVM. The rest I give root (/) root partition no subdivision, if you have more users in your system and the data in the user's home directory is very important, you can also separate as a partition, so that when the system fails, you re-install will not affect the user information loss in your system.
