• 2020年11月30日 CentOS 6 已經(jīng)不支持繼續(xù)使用了，目前第三方的鏡像中均已移除 CentOS 6 的源。阿里云的源和清華的源都已經(jīng)無法同步到 CentOS 6 的源。

• 在使用 yum install gcc-c++ 命令安裝時，會直接提示報錯

• 解決方法，修改 /etc/yum.repos.d/CentOS-Base.repo，修改結(jié)果如下：

# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the 
# remarked out baseurl= line instead.

• 然后使用命令，清除緩存

yum clean all
yum makecache

如下所示：

• 然后就可以安裝 gcc-c++

  
  
  下載安裝 gcc .jpg
• 安裝完成之后就可以使用 make 命令繼續(xù)安裝 Redis。
