如何在CentOS 7中安装GCC编译器？

GCC（GNU编译器集合的简称）是一组编程编译器的集合，包括C，C ++，Objective-C，Fortran，Java和Ada。GCC是GNU工具链的关键组件，也是大多数类Unix操作系统的标准编译器。自由软件基金会根据GNU通用公共许可证发行GCC。

在下面的教程中，我们将在CentOS 7上执行GCC安装。安装过程非常简单，并且不会超过10分钟。

步骤1：在服务器上执行更新

注意：您需要以root用户身份通过​​SSH登录到CentOS 7 VPS。

#ssh root@IP_Address -p Port_number

要更新服务器上所有已安装的软件包，可以使用以下命令

#yum -y update

步骤2：从存储库安装GCC

可以从官方CentOS资料库轻松安装GCC。运行以下命令以在服务器上安装GCC

#yum -y install gcc

输出：

步骤3：在CentOS 7上验证GCC安装

编译过程完成后。您可以检查是否已正确安装GCC。

# gcc --version

输出：
