# 操作1、安装SCL源相关软件包

yum install -y centos-release-scl \
centos-release-scl-rh

 

# 操作2、检查.repo文件

# 检查/etc/yum.repos.d/目录下是否存在与SCL相关的.repo文件
# 通常会有CentOS-SCLo-scl.repo和
# CentOS-SCLo-scl-rh.repo两个文件

ls /etc/yum.repos.d

随笔-centos7-更换源|升级gcc

 

 

目录

 

更换源

CentOS-Base.repo

参考：https://developer.aliyun.com/article/1577307

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

CentOS-Base.repo 
yum clean all && yum makecache

升级gcc版本

CentOS-SCLo-scl.repo   

[centos-sclo-sclo]
name=CentOS-7 - SCLo sclo
baseurl=https://mirrors.aliyun.com/centos/7/sclo/x86_64/sclo/
# mirrorlist=https://mirrors.aliyun.com?arch=$basearch&release=7&repo=sclo-sclo
gpgcheck=0
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-SIG-SCLo

 

 

CentOS-SCLo-scl-rh.repo

[centos-sclo-rh]
name=CentOS-7 - SCLo rh
baseurl=https://mirrors.aliyun.com/centos/7/sclo/x86_64/rh/
#mirrorlist=https://mirrors.aliyun.com?arch=$basearch&release=7&repo=sclo-rh
gpgcheck=0
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-SIG-SCLo

 

yum clean all && yum makecache

#安装 devtoolset-11-gcc devtoolset-11-gcc-c++ devtoolset-11-binutils

yum list devtoolset-*-gcc

yum -y install centos-release-scl
yum -y install devtoolset-11-gcc devtoolset-11-gcc-c++ devtoolset-11-binutils

#启用新的 GCC 环境，当前控制台生效：
scl enable devtoolset-11 bash 

#如果需要重启后也要生效：(可选) 

echo "source /opt/rh/devtoolset-11/enable" >>/etc/profile

 

  
 建议小优化：
为了防止重复添加或脚本报错，建议你这样写：

bash
复制
编辑
grep -q "devtoolset-11/enable" /etc/profile || echo "source /opt/rh/devtoolset-11/enable" >> /etc/profile
或者更安全一些，用 if 判断文件是否存在：

bash
复制
编辑
if [ -f /opt/rh/devtoolset-11/enable ]; then
    echo "source /opt/rh/devtoolset-11/enable" >> /etc/profile
fi
