我有 stunnel 为 Redis 提供 SSL。我有以下配置:
[redis]
CAfile= /etc/stunnel/ca.crt
accept = 636
cert = /etc/stunnel/server1.crt
connect = localhost:6379
key = /etc/stunnel/server1.key
verify = 2
我使用 openssl 生成所有密钥和证书:
# generate ca
openssl req -new -x509 \
-keyout "/etc/stunnel/ca.crt" \
-out "/etc/stunnel/ca.key" \
-days 365 \
-passout "pass:123456" \
-subj "$subj"
然后我通过生成密钥openssl genrsa -des3
然后我通过生成 csr 。然后我通过openssl req -new -key
生成签名证书并指向然后 我通过解密密钥openssl x509 -req
CA
CAkey
ca.crt
ca.key
openssl rsa
上述过程重复两次,以生成服务器和客户端密钥对。服务器进入 stunnel 配置,客户端进入 python 应用程序:
r = redis.Redis(host='localhost', ssl=True, port=636, db=0, ssl_certfile='client.crt', ssl_keyfile='client.key')
尝试运行 python 脚本时我得到:
redis.exceptions.ConnectionError: Error 1 connecting to localhost:636. [SSL: TLSV1_ALERT_UNKNOWN_CA] tlsv1 alert unknown ca (_ssl.c:590).
在隧道日志中:

这种行为对我来说不清楚:
- stunnel 配置中的 verify = 2 应将客户端的 CA 与其信任的 CA 进行比较
- stunnel 将 CAfile 设置为 CA,它对服务器密钥和客户端密钥进行了签名
- stunnel 说它是自签名证书并且 CA 未知
此外,openssl verify -CAfile=ca.crt <filename>
对于服务器和客户端来说都是可以的。
答案1
redis.exceptions.ConnectionError: Error 1 connecting to localhost:636. [SSL: TLSV1_ALERT_UNKNOWN_CA] tlsv1 alert unknown ca (_ssl.c:590).
您的客户端无法验证 CA 的证书。因此,请将其存储在系统的证书存储中或配置您的客户端以接受它。
在服务器上执行相同操作。
