Question

我有一个Redis集群，我希望设置stunnel，以加密进出每个主/从，以及来自redis之上的HAproxy层的流量。我已使用以下配置文件配置stunnel：

pid=/var/stunnel-redis.pid
foreground = yes
debug = info
output = stunnel.log

sslVersion = all
#options = NO_SSLv2
fips = no

socket = l:TCP_NODELAY=1
socket = r:TCP_NODELAY=1

[redis-server]
cert = /etc/stunnel/cert.pem
key = /etc/stunnel/key.pem
TIMEOUTclose = 0
accept = 0.0.0.0:7001
connect = 127.0.0.1:7002


[redis-client]
client = yes
accept = 127.0.0.1:7002
connect = 127.0.0.1:6379
CAfile = /etc/stunnel/redis.pem
verify = 0

编辑我应该解释每个服务是如何设置的，网络方式。

redis-server 绑定127.0.0.1:6379

stunnel redis-server 绑定0.0.0.0:7001

stunnel redis-client 绑定127.0.0.1:7002

redis客户端连接将在0.0.0.0:7001连接到stunnel的redis-server。然后，Stunnel将在127.0.0.1:7002上连接到redis-client，而stunnel的redis-client将在127.0.0.1:6379上连接到redis服务器。

尝试运行redis-cli -h my_remote_stunnel_ip -p 7001时，我在日志中收到以下错误：

2017.01.31 09:45:11 LOG3[16062]: SSL_accept: 140760FC: error:140760FC:SSL routines:SSL23_GET_CLIENT_HELLO:unknown protocol
2017.01.31 09:45:11 LOG5[16062]: Connection reset: 0 byte(s) sent to SSL, 0 byte(s) sent to socket

我尝试停用配置中的redis-client部分，我尝试将sslVersion更改为sslVersion = TLSv1，sslVersion = TLSv1.2。当我将sslVersion更改为sslVersion = TLSv1时，尝试连接时收到以下错误：

2017.01.31 09:38:33 LOG3[15830]: SSL_accept: 1408F10B: error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number

这是由于版本不匹配造成的吗？如果是这样，怎么样？两个守护进程都在同一主机上运行。

编辑： openssl s_client -connect的输出：7001 -tls1：
