1. Download CentOS


I'm using the DVD ISO, and I'm doing this to make it easy to use the CentOS Firefox on the next Docker pits to determine if the app in Docker is going to be able to access it properly.

Of course, if using the Curl command can also be tested, it depends on your preferences. I installed a CentOS version of 7, different versions may be slightly different, I will try to indicate in the process.

After the download is complete, you need to configure the system:

  1) Turn off SELinux

SELinux is a very pit of things, it will make a lot of network connection related services are not normal use, so it is a key step to turn it off.

Check the status of SELinux first:


If the display status is enforcing, which means that SELinux is turned on, use the following command to close it


Executing the above command will allow SELinux to shut down temporarily (no need to restart the system), if you want to completely shut it down:


Set SELinux to disabled and restart the system if you want to take effect after the modification. For the use of VIM, please own Baidu.

  2) Update Yum

Yum Update//This step is used to update Yum's Mirror list. This step is very slow, can not stand the use of NetEase's Mirror station.
2. Install the. NET core environment in the host
Yum Install  -ssl-o dotnet. tar. GZ https://// This address will vary with the version of. NET Core, Please go to the address below to view the specific address.  mkdirsudotar zxf dotnet. tar. gz-c/opt/dotnetLn -s/opt/dotnet/dotnet/usr/local/bin

For details, see: Https://

Note that the last ln command in/usr/local/bin is not necessarily the directory, and the min version of Centos7 is/usr/bin.


If you return:

Indicates that the installation was successful.

3. Install the Docker environment in the host
Yum Install Docker

If you return:

Indicates that the Docker installation was successful.

4. Create a working directory
cd/home/[your user name]mkdir Docker_demo

At this point, the construction of the entire environment is basically complete. The following article describes some of the basic concepts in Docker and how to create a mirror of your own based on the Docker image provided by Microsoft. Core-2. Create a Docker image Core Stuff-1. Preparation work
