kafka ssl证书开启脚本

更新了ssl证书脚本，添加了python版本的证书导出

python证书导出

keytool -export -alias graphca -keystore client.kafka.keystore -rfc -file certificate.pem
keytool -v -importkeystpre client.kafka.keystore -srcalias graphca -destkeystore cert_and_key.p12 -deststoretype PKCS12
openssl pkcs12 -in cert_and_key.p12 -nocerts -nodes
把输出---BEGIN PRIVATE KEY---到---END PRIVATE KEY---的拷贝到key.pem中

keytool -exportcert -alias graphca -keystore client.kafka.keystore -rfc -file CARoot.pem

python-kafka代码
因为SASL_SSL没有测试成功，导出的pkcs12格式的证书失败，python的demo只使用了SASL_PLAINTEXT的权限控制

from kafka import KafkaProducer, KafkaConsumer


print "step1"
consumer = KafkaConsumer("test1",
                         group_id = 'test-group',
                         bootstrap_server='dggts10012036:9094',
                         security_protocol="SASL_PLAINTEXT",
                         sasl_mechanism="PLAIN",
                         sasl_plain_username='admin',
                         sasl_plain_password='admin'
)

print "step2"
producer=KafkaProducer(bootstrap_server='dggts10012036:9094',
                       security_protocol="SASL_PLAINTEXT",
                       sasl_mechanism="PLAIN",
                       sasl_plain_username='admin',
                       sasl_plain_password='admin'
)

print "step3"
producer.send("test1", bytes("Hello World"))
producer.flush()

print "step4"

for msg in consumer:
    print msg.value
