## 2、修改`hosts`并启用`ipv6`
|

|

|
|
本文在`Ubuntu 16.04`测试通过，可以访问`Google、Facebok、Twitter、维基百科`等外网，其他平台`hosts`文件详见: [https://github.com/googlehosts/hosts](https://github.com/googlehosts/hosts/wiki/%E5%90%84%E5%B9%B3%E5%8F%B0-hosts-%E6%96%87%E4%BB%B6%E4%BD%8D%E7%BD%AE)
|
|||
|
|
|
|||
|
|
|
|||
|
|
### 2.1 使用`ipv6`的`host`
|
|||
|
|
1. 启动`ipv6`
|
|||
|
|
```
|
|||
|
|
sudo apt-get install miredo
|
|||
|
|
sudo gedit /etc/default/ufw
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
将`IPV6=no`改为`IPV6=yes`
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
sudo gedit /etc/sysctl.d/10-ipv6-privacy.conf
|
|||
|
|
# 将这两行改为0
|
|||
|
|
net.ipv6.conf.all.use_tempaddr = 2
|
|||
|
|
net.ipv6.conf.default.use_tempaddr = 2
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
1. 测试`ipv6`
|
|||
|
|
```
|
|||
|
|
ping6 ipv6.baidu.com
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
1. **校园网**是动态分配的`ipv6`地址，需要改成静态的。
|
|||
|
|
```
|
|||
|
|
sudo geidt /etc/sysctl.d/10-ipv6-privacy.conf
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
将`net.ipv6.conf.default.use_tempaddr`改为`0`
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
sudo sysctl --system
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
1. 修改`hosts`: [IPV6 hosts](https://github.com/lennylxx/ipv6-hosts)
|
|||
|
|
```
|
|||
|
|
sudo su
|
|||
|
|
curl https://github.com/lennylxx/ipv6-hosts/raw/master/hosts -L >> /etc/hosts
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
1. 刷新配置
|
|||
|
|
```
|
|||
|
|
sudo sysctl --system
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
### 2.2 `hosts`地址
|
|||
|
|
|
|||
|
|
## 3、修改下载源
|
|||
|
|
|
|||
|
|
### 3.1 `apt-get`下载源
|
|||
|
|
1. 首先测试适合系统最快的源：<br/> <img alt="" src="https://raw.githubusercontent.com/ds19991999/githubimg/master/picgo/20181104131030.png"/><br/> 这样它会自动匹配最佳的源，而不是网上大家所说的某某源快就选哪个，适合自己的源就是最快的源。 1. `Google搜索`该源地址并修改源
|
|||
|
|
```
|
|||
|
|
sudo gedit /etc/apt/sources.list
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
### 3.2 更换`pip`源
|
|||
|
|
|
|||
|
|
`pip`国内的一些镜像,换源之后出现python2版本过低的情况导致以前的包下载不了，那就直接将文件夹删除，就能恢复原来的源。
|
|||
|
|
|
|||
|
|
**`linux`更换`pip`源**:
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
cat > ~/.pip/pip.conf
|
|||
|
|
[global]
|
|||
|
|
index-url = https://pypi.tuna.tsinghua.edu.cn/simple
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
**`windows`更换`pip`源**:
|
|||
|
|
|
|||
|
|
>
|
|||
|
|
直接在user目录中创建一个pip目录，如：C:\Users\xx\pip，新建文件pip.ini，内容如下
|
|||
|
|
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
[global]
|
|||
|
|
index-url = https://pypi.tuna.tsinghua.edu.cn/simple
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
### 3.3 更换`GitHub`源
|
|||
|
|
|
|||
|
|
>
|
|||
|
|
其实改`hosts`的时候已经自动改好了，你可以进去查看一下，如果没有就通过下面这种方式加上去.
|
|||
|
|
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
sudo gedit /etc/hosts
|
|||
|
|
219.76.4.4 github-cloud.s3.amazonaws.com
|
|||
|
|
151.101.72.249 http://global-ssl.fastly.Net
|
|||
|
|
192.30.253.112 http://github.com
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
### 3.4 更换`npm`源
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
npm --registry https://registry.npm.taobao.org install express
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
npm install -g cnpm --registry=https://registry.npm.taobao.org
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
npm config get registry
|
|||
|
|
or
|
|||
|
|
npm info express
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
### 3.5 更换`yarn`源
|
|||
|
|
|
|||
|
|
>
|
|||
|
|
安装源和原来 npm 是一样的，可以通用
|
|||
|
|
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
yarn config set registry 'https://registry.npm.taobao.org'
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
验证：
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
yarn config get registry
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
## 4、与云服务器传输文件
|
|||
|
|
|
|||
|
|
为了避免每次传输文件的时候都要输入公网ip和密码挺麻烦的，所以索性就直接在服务器端配置本地`ssh`传输公匙，一劳永逸。
|
|||
|
|
|
|||
|
|
### 4.1 配置密匙验证
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
ssh-keygen -t rsa -C "your_email@example.com"
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
1. 在服务器端用户目录创建文件`~/.ssh/authorized_keys`，把本地`id_rsa.pub`公匙添加到这个文件中就可以了。1. 在本地用户目录创建文件`~/.ssh/config`，添加如下信息：
|
|||
|
|
```
|
|||
|
|
host servername
|
|||
|
|
user username
|
|||
|
|
hostname pubic-ip
|
|||
|
|
port 22
|
|||
|
|
identityfile ~/.ssh/id_rsa
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
其中`servername`随便填，与下文中的传输文件对应就行，`hostname`是公网`ip`。`user`填服务器端用户名，该用户需要有对系统文件的读写能力，直接用`root` 就好啦。
|
|||
|
|
|
|||
|
|
### 4.2 传输单个文件
|
|||
|
|
|
|||
|
|
1、从服务器上下载文件
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
scp servername:/path/filename /local_dir_path
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
2、上传本地文件到服务器
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
scp /path/filename servername:/path
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
### 4.3 传输文件夹
|
|||
|
|
|
|||
|
|
1、从服务器下载整个目录
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
scp -r servername:/remote_dir /local_dir
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
2、上传目录到服务器
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
scp -r /local_dir servername:/remote_dir
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
## 5、修改`DNS`
|
|||
|
|
|
|||
|
|
修改`DNS`是为了进一步提高浏览器查询`ip`地址的速度，提高网络流畅度。
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
sudo gedit /etc/network/interfaces
|
|||
|
|
# 加上
|
|||
|
|
dns-nameservers 8.8.8.8
|
|||
|
|
dns-nameservers 240c::6666
|
|||
|
|
sudo gedit /etc/resolv.conf
|
|||
|
|
# 加上
|
|||
|
|
nameserver 8.8.8.8
|
|||
|
|
nameserver 240c::6666
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
sudo /etc/init.d/resolvconf restart
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
此时重启`DNS`服务发现又没有了，解决办法是：在`/etc/resolvconf/resolv.conf.d/`目录下创建`tail`文件，写入
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
nameserver 8.8.8.8
|
|||
|
|
nameserver 240c::6666
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
这样再执行`sudo /etc/init.d/resolvconf restart`就`OK`了.
|
|||
|
|
|
|||
|
|
## 6、`SSR`服务器搭建并配置`ipv6`隧道代理
|
|||
|
|
1. 申请`ipv6`的`ip`: [https://www.tunnelbroker.net/register.php](https://www.tunnelbroker.net/register.php)
|
|||
|
|
>
|
|||
|
|
注意几个`ip`的区别
|
|||
|
|
|
|||
|
|
1. 按照网上教程一键脚本配置搞定.
|
|||
|
|
## 7、搭建`aria2`服务器
|
|||
|
|
|
|||
|
|
>
|
|||
|
|
我的服务器地址，[https://download.creat.kim](https://download.creat.kim) , 你们可以上去看看，就是按照作者的教程搭的，我搭建的没有提供公共下载服务。
|
|||
|
|
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
nohup aria2c --enable-rpc --rpc-listen-all=true --rpc-allow-origin-all &
|
|||
|
|
python -m SimpleHTTPServer 端口号 &
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
## 8、`nginx`多端口不同域名配置
|
|||
|
|
|
|||
|
|
>
|
|||
|
|
直接在配置文件加个`server`函数搞定
|
|||
|
|
|
|||
|
|
|
|||
|
|
好啦，`Ubuntu 16.04`网络环境就全部配置好啦，最重要的是可以上外网，下载网速比以前快很多倍。<br/> **Enjoy it！**
