Subject [jira] [Commented] (ZOOKEEPER-2125) SSL on Netty client-server communication
Date Thu, 04 Oct 2018 14:41:00 GMT

    [ https://issues.apache.org/jira/browse/ZOOKEEPER-2125?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16638309#comment-16638309

Martin M commented on ZOOKEEPER-2125:
-------------------------------------

In this Jira item it is indicated that in order to configure SSl, one has to specified secureClientPort
in zoo.cfg.

However, the documentation (https://zookeeper.apache.org/doc/r3.5.2-alpha/zookeeperReconfig.html)
says:
{noformat}
Starting with 3.5.0 the clientPort and clientPortAddress configuration parameters should
no longer be used
{noformat}
I have tried setting the SSL port in the dynamic configuration, but it doesnt work. The secureClientPort
must be specified in zoo.cfg.
When i specify both securePortClient in zoo.cfg and the dynamic configuration, ZK server doesnt
start anymore.
How to fix this?
Thanks

> Supporting SSL on Netty client-server communication. 
> 1. It supports keystore and trustore usage. 
> 2. It adds an additional ZK server port which supports SSL. This would be useful for
rolling upgrade.
> RB: https://reviews.apache.org/r/31277/
> The patch includes three files: 
> * testing purpose keystore and truststore under "$(ZK_REPO_HOME)/src/java/test/data/ssl".
Might need to create "ssl/".
> * latest ZOOKEEPER-2125.patch
> h2. How to use it
> You need to set some parameters on both ZK server and client.
> h3. Server
> You need to specify a listening SSL port in "zoo.cfg":
> {code}
> secureClientPort=2281
> {code}
> Just like what you did with "clientPort". And then set some jvm flags:
> {code}
> export SERVER_JVMFLAGS="-Dzookeeper.serverCnxnFactory=org.apache.zookeeper.server.NettyServerCnxnFactory
-Dzookeeper.ssl.keyStore.location=/root/zookeeper/ssl/testKeyStore.jks -Dzookeeper.ssl.keyStore.password=testpass
-Dzookeeper.ssl.trustStore.location=/root/zookeeper/ssl/testTrustStore.jks -Dzookeeper.ssl.trustStore.password=testpass"
> {code}
> Please change keystore and truststore parameters accordingly.
> h3. Client
> You need to set jvm flags:
> {code}
> export CLIENT_JVMFLAGS="-Dzookeeper.clientCnxnSocket=org.apache.zookeeper.ClientCnxnSocketNetty
-Dzookeeper.client.secure=true -Dzookeeper.ssl.keyStore.location=/root/zookeeper/ssl/testKeyStore.jks
-Dzookeeper.ssl.keyStore.password=testpass -Dzookeeper.ssl.trustStore.location=/root/zookeeper/ssl/testTrustStore.jks
-Dzookeeper.ssl.trustStore.password=testpass"
> {code}
> change keystore and truststore parameters accordingly.
> And then connect to the server's SSL port, in this case:
> {code}
> bin/zkCli.sh -server 127.0.0.1:2281
> {code}
> If you have any feedback, you are more than welcome to discuss it here!
