CentOS7.8离线安装Docker24.0.2,离线安装gcc与g++环境

背景

有时候运维时要求在内网环境下操作,即服务器无法连接互联网,那么就无法通过 yum 源在线安装。。这时,一般通过以下3种方式来安装需要的软件:

  1. 下载源码包编译安装;
  2. 下载对应平台编译好的安装包,解压即可;
  3. 下载rpm包,本地安装。

gcc与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

在离线环境下,如果需要进行源码编译安装,比如 NginxRedis 等,则要求具备 gccg++ 这些基础环境。以下通过 rpm 包进行 gccg++ 的离线安装。

gcc

进入 /opt/gcc 目录,执行以下命令安装 gcc

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

其中 --nodeps 表示忽略依赖检查, --force 表示强制安装。

小总结

当你的服务器无法连接到互联网时。这可能是由于网络限制、安全策略或其他原因造成的。在这种情况下,就需要手动下载在可以访问互联网的机器上,下载 Docker 24.0.2 的离线安装包,并在目标服务器上进行安装。

另外,可能需要离线安装 GCCG++ 环境:

  1. 当无法通过网络连接下载和安装GCCG++时。
  2. 当需要在没有网络连接的环境中进行编译和构建C或C++代码时。

要离线安装GCC和G++环境,除了上述的rpm,还可以按照以下步骤进行操作:

  1. 在具有Internet连接的计算机上,下载GCC和G++的离线安装包(通常是tar.gz或tar.xz格式)。
  2. 将离线安装包传输到目标计算机上。
  3. 在目标计算机上解压离线安装包。
  4. 进入解压后的目录,并运行以下命令进行配置和安装:
./configure
make
sudo make install

这将配置、编译和安装 GCCG++ 环境。安装完成后,您可以在目标计算机上使用 GCCG++ 编译和构建 CC++ 代码,比如我们经常以源码方式安装的 NginxRedis
