python - peewee mysql SSL : CERTIFICATE_VERIFY_FAILED

Question

python 3.4.3、pymysql 0.6.7 和 0.7.1、mysql 5.5.23 和 5.5.4x 无法使用 ssl 选项连接到 mysql。 使用 mysql workbench 和 mysql-client 安全连接工作正常。 我在debian和windows的两台mysql服务器上测试过

这里是代码和解释

制作证书

openssl genrsa 2048 > ca-key.pem; \
openssl req -sha1 -new -x509 -nodes -days 3650 -key ca-key.pem > ca-cert.pem; \
openssl req -sha1 -newkey rsa:2048 -days 730 -nodes -keyout server-key.pem > server-req.pem; \
openssl x509 -sha1 -req -in server-req.pem -days 730  -CA ca-cert.pem -CAkey ca-key.pem -set_serial 01 > server-cert.pem; \
openssl rsa -in server-key.pem -out server-key.pem; \
openssl req -sha1 -newkey rsa:2048 -days 730 -nodes -keyout client-key.pem > client-req.pem; \
openssl x509 -sha1 -req -in client-req.pem -days 730 -CA ca-cert.pem -CAkey ca-key.pem -set_serial 01 > client-cert.pem; \
openssl rsa -in client-key.pem -out client-key.pem;

用户创建

CREATE DATABASE dbname;
GRANT ALL PRIVILEGES ON dbname.* TO 'u1'@'%' IDENTIFIED BY '12345' REQUIRE SSL;
FLUSH PRIVILEGES;

代码

from __future__ import print_function
import pymysql

#conn = pymysql.connect(host='localhost', port=3306, user='root', passwd='', db='mysql')
conn = pymysql.connect(host='localhost', port=3306, user='u1', passwd='12345', db='dbname', ssl = {'key': 'ssl/client-key.pem', 'cert': 'ssl/client-cert.pem', 'ca': 'ssl/ca-cert.pem'})

cur = conn.cursor()
#cur.execute("SELECT Host,User FROM user")
cur.execute("SHOW TABLES")

print(cur.description)
print()
for row in cur:
    print(row)
cur.close()
conn.close()

错误

During handling of the above exception, another exception occurred:

    conn = pymysql.connect(host='localhost', port=3306, user='u1', passwd='12345', db='dbname', ssl = {'key': 'ssl/client-key.pem', 'cert': 'ssl/client-cert.pem', 'ca': 'ssl/ca-cert.pem'})

    raise exc
pymysql.err.OperationalError: (2003, "Can't connect to MySQL server on 'localhost' ([SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:600))")

更新: 我错过了这部分说明:

```
Whatever method you use to generate the certificate and key files, the Common Name value used for the server and client certificates/keys must each differ from the Common Name value used for the CA certificate. Otherwise, the certificate and key files will not work for servers compiled using OpenSSL.
```

当 OpenSSL 提示您输入每个证书的通用名称时，请使用不同的名称。

但是它会帮助并引发新的错误: 首先-dhkey 不够用，我正在将测试 mysql 服务器更新到 5.7.11 它有助于并引发新的错误，即通用名称与 localhost 不匹配 我已经用新的通用名称 localhost

重新生成了证书

它再次向我显示错误 - ([SSL: CERTIFICATE_VERIFY_FAILED] 证书验证失败 (_ssl.c:600))

Answer 1

尝试:

conn = pymysql.connect(host='localhost', port=3306, user='u1', passwd='12345', db='dbname', ssl={'ssl': {'key': ' ssl/client-key.pem', 'cert': 'ssl/client-cert.pem', 'ca': 'ssl/ca-cert.pem'}})

有同样的问题，它对我有用。
