安装gcc时提示"HTTP Error 416"。

wget只下载了14526904字节。

$ ls -l gcc-4.8.5-36.el7_6.2.x86_64.rpm
-rw-r--r--. 1 root root 14526904 Jul 23 08:41 gcc-4.8.5-36.el7_6.2.x86_64.rpm

下面是位于yum缓存中的文件:

$ ls -l /var/cache/yum/x86_64/\$releasever/updates/packages/gcc-4.8.5-36.el7_6.2.x86_64.rpm
-rw-r--r--. 1 root root 14526904 Jul 23 08:41 /var/cache/yum/x86_64/$releasever/updates/packages/gcc-4.8.5-36.el7_6.2.x86_64.rpm

文件大小应该是16960856，下回来却只有14526904。又是"邪恶的Cache服务"惹的祸，
这次的EvilCache位于45.252.224.79。

临时解决办法是挂加密代理手工下载正确版本，放到如下目录:

/var/cache/yum/x86_64/\$releasever/updates/packages/

或者用HTTPS下载:

$ wget https://.../centos/7.6.1810/updates/x86_64/Packages/gcc-4.8.5-36.el7_6.2.x86_64.rpm
$ rpm -Uvh gcc-4.8.5-36.el7_6.2.x86_64.rpm

或者

$ rpm -Uvh https://.../centos/7.6.1810/updates/x86_64/Packages/gcc-4.8.5-36.el7_6.2.x86_64.rpm

可以配置yum使用代理:

$ vi /etc/yum.conf

--------------------------------------------------------------------------
[main]
...
#proxy=http://<Proxy-Server-IP-Address>:<Proxy_Port>
#proxy_username=<Proxy-User-Name>
#proxy_password=<Proxy-Password>
proxy=http://192.168.65.1:8080
--------------------------------------------------------------------------

重新执行"yum install gcc"即可。
