gocql中的SSL选项

Question

In my Cassandra config I have enabled user authentication and connect with cqlsh over ssl. I'm having trouble implementing the same with gocql, following is my code:

cluster := gocql.NewCluster("127.0.0.1")
cluster.Authenticator = gocql.PasswordAuthenticator{
    Username: "myuser",
    Password: "mypassword",
}
cluster.SslOpts = &gocql.SslOptions {
    CertPath: "/path/to/cert.pem",
}

When I try to connect I get following error:

 gocql: unable to create session: connectionpool: unable to load X509 key pair: open : no such file or directory

In python I can do this with something like:

from cassandra.cluster import Cluster
from cassandra.auth import PlainTextAuthProvider
USER = 'username'
PASS = 'password'
ssl_opts = {'ca_certs': '/path/to/cert.pem',
        'ssl_version': PROTOCOL_TLSv1
}
credentials = PlainTextAuthProvider(username = USER, password = PASS)
# define host, port, cqlsh protocaol version
cluster = Cluster(contact_points= HOST, protocol_version= CQLSH_PROTOCOL_VERSION, auth_provider = credentials, port = CASSANDRA_PORT)

I checked the gocql and TLS documentation here and here but I'm unsure about how to set ssl options.

You're adding a cert without a private key, which is where the "no such file or directory" error is coming from.

Your python code is adding a CA; you should do the same with the Go code:

gocql.SslOptions {
    CaPath: "/path/to/cert.pem",
}
