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:
rpm
包,本地安装。[root@etl opt]# uname -a

开机自启。

包括启动、查看状态、停止、重启命令。启动之后就可以拉取镜像、运行容器啦。

在离线环境下,如果需要进行源码编译安装,比如 Nginx
、 Redis
等,则要求具备 gcc
与 g++
这些基础环境。以下通过 rpm
包进行 gcc
与 g++
的离线安装。
gcc
与 g++
的 rpm
包下载链接: https://pan.baidu.com/s/1I4kn_vF9KX0dZF9cr4JFnw?pwd=ruks 提取码: ruks
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。
[root@etl gcc]# rpm -ivh *.rpm --nodeps --force

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 GCC
和 G++
环境:
GCC
和G++
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:
./configure
make
sudo make install
这将配置、编译和安装 GCC
和 G++
环境。安装完成后,您可以在目标计算机上使用 GCC
和 G++
编译和构建 C
或 C++
代码,比如我们经常以源码方式安装的 Nginx
、 Redis
。
