This article will explain in detail how to use SSL on EOS.IO nodes. The content of the article is of high quality, so the editor shares it for you as a reference. I hope you will have some understanding of the relevant knowledge after reading this article.

First of all, you must use DAWN-2018-04-27-ALPHA or above.

If you run nodeos-version, it should output 2594537369. Otherwise, you have to update the version.

To update, run your copy of eos repo:

$cd [EOSIO_DIR] $git pull$ git checkout DAWN-2018-04-27 git submodule update Alpha-- recursive$. / eosio_build.sh$ cd build$ sudo make install

Use Certbot to obtain SSL certificates for your domain:

$sudo add-apt-repository ppa:certbot/certbot$ sudo apt-get update$ sudo apt-get install certbot

Certbot needs to listen for certificate generation on port 80. If you have any services that use it, please stop first and then run:

$sudo certbot certonly-- standalone-- preferred-challenges http-d your-domain

Now copy the generated files to the testnet folder:

$cd [TESTNET_FOLDER] $sudo cp / etc/letsencrypt/live/your-domain/fullchain.pem. $sudo cp / etc/letsencrypt/live/your-domain/privkey.pem. $sudo chown user:user fullchain.pem privkey.pem configuration nodeos

Edit the config.ini file and add the following line:

Https-server-address = 0.0.0.0:443https-certificate-chain-file = / [TESTNET_FOLDER] / fullchain.pemhttps-private-key-file = / [TESTNET_FOLDER] / privkey.pem

If you want to completely disable unsafe HTTP, just set it (commenting out the line won't work)

Http-server-address =

Start nodeos and go to https://your-domain/v1/chain/get_info for inspection! You should see a green lock in chrome, which indicates that the TLS connection is successful.

If there is a problem, look at the first line of the log file stderr.txt.

So much for sharing about how EOS.IO nodes use SSL. I hope the above content can be helpful to you and learn more. If you think the article is good, you can share it for more people to see.
