我已经为Java KafkaBroker创建了KeyStore,并为librdKafka创建了必需的证书,当这些组件尝试与SSL / TLS进行通信时,我遇到了以下错误。


ssl://172.25.93.195:11307/bootstrap: SSL handshake failed: s23_clnt.c:601: error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol: (after 4ms in state CONNECT)



然后我进行了TCP转储并进行了分析。它给出以下输出。 (librdkafka-172.25.31.43,KafkaBroker- 172.25.31.42),


"1","0.000000","172.25.31.43","172.25.31.42","TCP","74","59116 → 26307 [SYN] Seq=0 Win=14600 Len=0 MSS=1460 SACK_PERM=1 TSval=523149518 TSecr=0 WS=128"

"7","0.000773","172.25.31.42","172.25.31.43","TCP","66","26307 → 59116 [FIN, ACK] Seq=8 Ack=140 Win=15616 Len=0 TSval=523134399 TSecr=523149518"


考虑第4行和第6行,它表明librdkafka通过SSLv2发送“客户端问候”,而KafkaBroker通过“ TLSv1.2”发送确认。


为了验证生成的密钥,我很累从openssl s_client连接,其输出如下所示,


openssl s_client -debug -msg -connect 172.25.31.42:26307  -CAfile $SYSTEM_CONFIGS/MHV/ca-cert -key $SYSTEM_CONFIGS/MHV/producer_client.key -pass "pass:abc123" -cert $SYSTEM_CONFIGS/MHV/producer_client.pem

最佳答案

此问题的根本原因是在分布式计算机中安装了不同版本或较旧版本的OpenSSL。

例如

|---------------------|------------------|------------------|
|      Process        |     Machine      | OpenSSL Version  |
|---------------------|------------------|------------------|
|     KafkaBroker     |   168.25.33.12   |       1.0.1      |
|---------------------|------------------|------------------|
| librdKafka Producer |   168.25.33.13   |       0.9.8j     |
|---------------------|------------------|------------------|


可以通过将openssl版本升级到1.0.1来解决

注意:-要启用SSL支持,openssl的最低版本应为1.0.1。
