设置 proxy

Git proxy

In .gitconfig

[http]
	proxy = http://10.206.133.47:3128
[user]
	email = name@email.com
	name = name

APT PROXY

In file /etc/apt/apt.conf

	Acquire::http::proxy "http://10.206.133.47:3128/";
	Acquire::https::proxy "http://10.206.133.47:3128/";
	Acquire::http::No-Cache=true;
	Acquire::https::No-Cache=true;
	Acquire::http::Pipeline-Depth '0';

PIP proxy

In file /root/.pip/pip.conf

[global]
index-url = http://pypi.douban.com/simple
proxy=http://10.206.133.47:3128
[install]
trusted-host=pypi.douban.com

设置 proxy时出现的各种错误

fatal: unable to access ‘https://github.com/spdk/spdk/’: server certificate verification failed. CAfile: none CRLfile: none

export GIT_SSL_NO_VERIFY=1 

git config --global http.sslVerify false

export http_proxy=http://10.206.133.47:3128

第二个错误：该错误 是因为没有设置proxy

Looking in indexes: http://pypi.douban.com/simple
WARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) 
after connection broken by 'ConnectTimeoutError(<urllib3.connection.HTTPConnection

• fatal: unable to access ‘https://github.com/spdk/spdk/’: server certificate verification failed. CAfile: none CRLfile: none

export GIT_SSL_NO_VERIFY=1 

git config --global http.sslVerify false

export http_proxy=http://10.206.133.47:3128

Install rust failed on SSL certificates

I try to install with the simplest way:

$ curl https://sh.rustup.rs -sSf | sh

and it ends with:

info: syncing channel updates for 'stable-x86_64-unknown-linux-gnu'
error: could not download file from 'https://static.rust-lang.org/dist/channel-rust-stable.toml.sha256' to '/home/ildar/.rustup/tmp/smpm6z49tivc6git_file

info: caused by: [60] Peer certificate cannot be authenticated with given CA certificates (SSL certificate problem: unable to get local issuer certificate)
rustup: command failed: /tmp/.private/ildar/tmp.8kVhcIBdVQ/rustup-init

Solution: add correct certificates in /usr/local/share/ca-certificates/ , then sudo update-ca-certificates
