fabric-ca-server使用ssl连接到mysql

Question

I read this doc https://hyperledger-fabric-ca.readthedocs.io/en/release-1.0/users-guide.html#mysql-ssl-configuration to set fabric-ca-server connect to mysql with ssl. I use openssl generate the CA files, and copy client side files to the fabric-ca-server(by volumns in docker-compose)

here is the variables about tls in fabric-ca-server:

- FABRIC_CA_SERVER_DB_TLS_CERTFILES=/etc/hyperledger/fabric-ca-server-config/mysql-ssl/ca.pem
- FABRIC_CA_SERVER_DB_TLS_CLIENT_CERTFILE=/etc/hyperledger/fabric-ca-server-config/mysql-ssl/client-cert.pem
- FABRIC_CA_SERVER_DB_TLS_CLIENT_KEYFILE=/etc/hyperledger/fabric-ca-server-config/mysql-ssl/client-key.pem

I get logs in fabric-ca containers:

I also use other ways to connect to the mysql:one is starting a another mysql container as a client to connect to mysql server with ssl ;another is using MySQLWorkbench in my host machine with ssl by exposing mysql server port to my host machine.

with this state SELECT sbt.variable_value AS tls_version, t2.variable_value AS cipher, processlist_user AS user, processlist_host AS host FROM performance_schema.status_by_thread AS sbt JOIN performance_schema.threads AS t ON t.thread_id = sbt.thread_id JOIN performance_schema.status_by_thread AS t2 ON t2.thread_id = t.thread_id WHERE sbt.variable_name = 'Ssl_version' and t2.variable_name = 'Ssl_cipher' ORDER BY tls_version;

enter image description here

so , I wonder the certification I generated works, but something wrong in the fabric-ca code ?

Answer 1

with help and trying many times, I find the solution:

first, the environment of ca in docker-compose.yml must set as

FABRIC_CA_SERVER_DB_DATASOURCE=****:****@tcp(mysql_ca:3306)/fabric_ca?parseTime=true&tls=custom

the mysql_ca is name of mysql container, and the &tls=custom must be added.

second , while generating the ssl cert, the common name must be same as the name of mysql container.also, the common name can be specified in cli:

openssl req -newkey rsa:2048 -days 3600 \\ -nodes -keyout server-key.pem -subj /CN=mysql_ca -out server-req.pem
