安装 shadowsocks-qt5
sudo add-apt-repository ppa:hzwhuang/ss-qt5
sudo apt-get update
sudo apt-get install shadowsocks-qt5 >原来的如下:
http://ppa.launchpad.net/hzwhuang/ss-qt5/ubuntu bionic main
改成如下: http://ppa.launchpad.net/hzwhuang/ss-qt5/ubuntu artful main
安装tsocks
apt-get install tsocks
使用前设置conf文件
vi /etc/tsocks.conf
做一个简单的配置就好了：
local = 192.168.1.0/255.255.255.0 #local表示本地的网络，也就是不使用socks代理的网络
local = 127.0.0.0/255.0.0.0
server = 127.0.0.1 #socks服务器的IP
server_type = 5 #socks服务版本
server_port = 1080 ＃socks服务使用的端口
Kubectl
Add apt key
sudo tsocks curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key add
Next add a repository by creating the file /etc/apt/sources.list.d/kubernetes.list and enter the following content:
deb http://apt.kubernetes.io/ kubernetes-xenial main
Save and close that file. Install Kubernetes with the following commands:
sudo tsocks apt-get update
sudo tsocks apt-get install -y kubectl
