Ubuntu 更换源

• 起源: 双十一云服务器优惠，同时买了阿里云，腾讯云的和华为云的服务器。阿里云和华为云服务器都是 ubuntu，使用后发现华为云的服务器上使用的源相当的慢，阿里云的源速度是非常的理想的，所以把华为云的 Ubuntu 切换成了阿里的源。
• 步骤如下:

1. 先备份:

sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak 

2. 将source.list文件内容替换成下面的

deb http://mirrors.aliyun.com/ubuntu/ trusty main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ trusty-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ trusty-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ trusty-proposed main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ trusty-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ trusty main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ trusty-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ trusty-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ trusty-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ trusty-backports main restricted universe multiverse

3. 更新

sudo apt-get update

• 对比了之后发现阿里云服务器上用的是阿里云的源，截图参考下

• 其实可以将阿里云的源文件直接拷贝到华为云上来(包括腾讯云，因为网络还是没有阿里云的好)。先用着看看...
