CentOS7.8 offline installation of Docker24.0.2, offline installation of gcc and g++ environment

background

Sometimes it is required to operate in the intranet environment during operation and maintenance, that is, the server cannot connect to the Internet, so it cannot be yuminstalled online through the source. . At this time, the required software is generally installed in the following three ways:

1. Download the source package to compile and install;
2. Download the compiled installation package for the corresponding platform and unzip it;
3. Download rpmthe package and install it locally.

gcc and g++

[root@etl opt]# gcc -v
-bash: gcc: 未找到命令

[root@etl opt]# g++ -v
-bash: g++: 未找到命令

In an offline environment, if you need to compile and install source code, such as Nginx, Redisetc., you need to have gccand g++these basic environments. The following is an offline installation of and with rpmthe package .gccg++

gccDownload link with g++the rpmpackage: https://pan.baidu.com/s/1I4kn_vF9KX0dZF9cr4JFnw?pwd=ruks Extraction code: ruks

gcc

Enter /opt/gccthe directory and execute the following command to install gcc:

rpm -ivh *.rpm --nodeps --force

Among them --nodeps, means to ignore the dependency check, --forcemeans to force the installation.

[root@etl gcc]# rpm -ivh *.rpm --nodeps --force

small summary

When your server cannot connect to the internet. This could be due to network restrictions, security policies, or other reasons. In this case, you need to manually download the offline installation package downloaded on a machine with Internet access, Docker 24.0.2and install it on the target server.

Additionally, offline installations GCCand G++environments may be required:

1. GCCWhen it is not possible to download and install and over a network connection G++.
2. When you need to compile and build C or C++ code in an environment without a network connection.

To install GCC and G++ environment offline, in addition to the above rpm, you can also follow the steps below:

1. On a computer with an Internet connection, download the offline installation packages for GCC and G++ (usually in tar.gz or tar.xz format).
2. Transfer the offline installation package to the target computer.
3. Unzip the offline installation package on the target computer.
4. Enter the decompressed directory, and run the following commands to configure and install:

./configure
make
sudo make install

This will configure, compile and install the GCCand G++environment. GCCAfter the installation is complete, you can use and G++compile and build Cor code on the target computer C++, such as we often install in source code Nginx, Redis.
