HI,Cephers:
I just use Mimic Ceph for Dashboard. I just do as http://docs.ceph.com/docs/mimic/mgr/dashboard/
When install a self-signed certificate as build-in commend , it stuck ERR like as bellow:
[root@localhost ~]# ceph dashboard create-self-signed-cert
Error EINVAL: Traceback (most recent call last):
File "/usr/lib64/ceph/mgr/dashboard/module.py", line 319, in handle_command
self.create_self_signed_cert()
File "/usr/lib64/ceph/mgr/dashboard/module.py", line 328, in create_self_signed_cert
pkey.generate_key(crypto.TYPE_RSA, 2048)
Error: [('rsa routines', 'RSA_BUILTIN_KEYGEN', 'BN lib')]
I check the /usr/lib64/ceph/mgr/dashboard/module.py . And execute in local env. it's OK.
```
[root@localhost ~]# cat xx.py
from OpenSSL import crypto
from uuid import uuid4
def create_self_signed_cert():
# create a key pair
pkey = crypto.PKey()
pkey.generate_key(crypto.TYPE_RSA, 2048)
# create a self-signed cert
cert = crypto.X509()
cert.get_subject().O = "IT"
cert.get_subject().CN = "ceph-dashboard"
cert.set_serial_number(int(uuid4()))
cert.gmtime_adj_notBefore(0)
cert.gmtime_adj_notAfter(10*365*24*60*60)
cert.set_issuer(cert.get_subject())
cert.set_pubkey(pkey)
cert.sign(pkey, 'sha512')
cert = crypto.dump_certificate(crypto.FILETYPE_PEM, cert)
print cert
pkey = crypto.dump_privatekey(crypto.FILETYPE_PEM, pkey)
print pkey
create_self_signed_cert()
[root@localhost ~]# python xx.py
