tomcat-cluster-redis-session-manager's Introduction

Tomcat Clustering Redis Session Manager

The Redis session manager is pluggable one. It stores session into Redis for easy distribution of HTTP Requests across a cluster of Tomcat servers.

Here the Sessions are implemented as non-sticky (means, each request can able to go to any server in the cluster, unlike the Apache provided Tomcat clustering setup.)

Request Sessions will be stored into Redis immediately (Session attributes must be Serializable), for the use of other servers. When tomcat receives a request from the client, Sessions are loaded directly from Redis.

Supports Redis default, sentinel and cluster mode, based on the configuration.

Going forward, we no need to enable sticky session (JSESSIONID) in Load Balancer.

Supports:

Apache Tomcat 7
Apache Tomcat 8
Apache Tomcat 9
Apache Tomcat 10

Pre-requisite:

jedis.jar
commons-pool2.jar
commons-logging.jar

more details.. https://github.com/ran-jit/tomcat-cluster-redis-session-manager/wiki

Steps to be done,

Copy the downloaded jars to your tomcat/lib directory.

tomcat/lib/

Add tomcat system property "catalina.base".

catalina.base="TOMCAT_LOCATION"
example: env "catalina.base=/opt/tomcat" bash

Copy the redis-data-cache.properties file to your tomcat/conf directory and update your Redis server details.

tomcat/conf/redis-data-cache.properties

Add the below two lines in your tomcat/conf/context.xml file.

<Valve className="tomcat.request.session.redis.SessionHandlerValve" />
<Manager className="tomcat.request.session.redis.SessionManager" />

Verify the session expiration time in tomcat/conf/web.xml file.

<session-config>
  <session-timeout>60</session-timeout>
</session-config>

Note:

All your session attribute values must implement java.io.Serializable.

Configuration Properties:

Property	Description
redis.hosts	Redis server running instance IP address and port number - ex: 127.0.0.1:6379, 127.0.0.2:6379, 127.0.0.2:6380, .. - default: 127.0.0.1:6379
redis.password	Redis protected password
redis.database	Redis database selection. (Numeric value) - default: 0
redis.timeout	Redis connection timeout - default: 2000 ms
redis.cluster.enabled	To enable redis cluster mode - default: false - supported values: true/false
redis.sentinel.enabled	To enable redis sentinel mode - default: false - supported values: true/false
redis.sentinel.master	Redis sentinel master name - default: mymaster
lb.sticky-session.enabled	To enable redis and standard session mode If enabled, Must be enabled sticky session in your load balancer configuration. Else this manager may not return the updated session values Session values are stored in local jvm and redis If redis is down/not responding, requests uses jvm stored session values to process user requests. Redis comes back the values will be synced - default: false
session.persistent.policies	session persistent policies. - policies - DEFAULT, SAVE_ON_CHANGE, ALWAYS_SAVE_AFTER_REQUEST SAVE_ON_CHANGE: every time session.setAttribute() or session.removeAttribute() is called the session will be saved. ALWAYS_SAVE_AFTER_REQUEST: force saving after every request, regardless of whether or not the manager has detected changes to the session. - default: DEFAULT
redis.sso.timeout	single-sign-on session timeout. - default: 0 ms (-no expiry)

JedisPool.getResource() can cause blocked and fake death

We need to solve the problem this way : poolConfig.setMaxWaitMillis(10 * 1000);

SingleSignOn valve support

Hi, would it be possible to add support for SingleSignOn valve using redis as session storage cache ?
We would like to be able to use tomcats SSO functionality while using redis as SSO session storage.

RequestSessionManager中同步session到redis时长设置bug

Web application is throwing 500 internal server error for the very first http request, due to uncertainity of the redisdb instance (redisdb instance may be down or it might be configured to read only access)

Hi Ranjit,

I was playing with your solution for sharing session in cluster of tomcat servers by deploying a web application in multiple servers , this solution is awesome, however i came across one challenge, that is as below.

Due to some uncertainty of the redisdb instance, instance may not be up, or it may be configured with read only access, in this case when i deploy my war file and hit very first time http request to my server to access welcome page of my application

Due to unavailability of the redisdb instance or if it has only read only access application is getting stopped due to 500 internal server error thrown by api's of tomcat-cluster-redis-session-manager.jar in tomcat server.

is there any option in this solution?. like if any such redisdb instance errors occurs can it be ignored by exception handling ?. to avoid 500 internal server error.....and let the http request served successfully without any error.

due to properly unavailability of redisdb instance entire application is going down.
(in this case we no need of session sharing at least expecting our application should up and running fine )

The second step of this catalina.base="TOMCAT_LOCATION".

Hi, @ran-jit I have encountered some problems, now I got it.

My System environment is Centos7
The second step of this readme document
- Add tomcat system property "catalina.base".
  - catalina.base="TOMCAT_LOCATION"
    - example: export catalina.base=/opt/tomcat
the "catalina.base" have a invalid symbol dot "."

as follows : modify catalina.base to catalina_base

vi /etc/profile
export catalina_base=/your/opt//tomcat
source /etc/profile

thanks a lot !

How get I set redis pool connection configration?

There is no way change redis connection pool configuration value.

I saw into the source. it set 5 connection pool.

but I think it is not enough large scale running environment.

it should be possible to change.

it the 5 Seconds timeout from this error message configurable? Background is that i've confiured my sentinels to switch over master after one second, so this could be much shorter so people won't recognize the outage...

Support system variables in 3.0.1 version

Hi, we want to use your library, but we couldn't use jedis v3, so we have chosen 3.0.1 version of session manager, but we also need system environment support feature, which was introduced only in 3.0.4 version. Is it possible to add this feature to 3.0.1 version please?

Would you add a license for this software?

There is no license statement. And for some regulations, we can not use it without license. Would you add the license statement for this?

Can't set password when the value of cluster.enabled is yes

if use redis cluster in project, why not support the password of redis?

add the interpretation of variables in the configuration file redis-data-cache.properties

Hi,

Thanks for this plugin that works perfectly :)

So I have a suggestion, just like the other tomcat conf files, it would be nice to be able to use java variables passed at tomcat startup to make dynamic the REDIS_PORT or REDIS_SERVER information, so in a docker context, the conf file would look like this

redis.hosts=${REDIS_SERVER}:${REDIS_PORT}

and deployment would be given the right value depending on the environment.
Currently I have to have a script that does sed before starting the tomcat :(

thanks :)

Project integration

Can it be integrated in the project, not under Tomcat

java.lang.NoSuchMethodError: tomcat.request.session.redis.SessionManager.getContext()Lorg/apache/catalina/Context;

there has an error in the class of SessionManager in the line of 129: getContext()

Can you point to a specific example?

catalina.base="TOMCAT_LOCATION"?

Connection to a remote Redis server

Hello,

I'd like to implement jedis on an application that runs with Tomcat and Java,
My redis server is not on the same server that my application and, following the readme, I modified the file redis-data-cache.properties to indicate the IP of my redis server.
However, it seems that this configuration file is not read because the application logs throw me errors such as "java-error: Caused by: redis.clients.jedis.exceptions.JedisConnectionException: Failed connecting to host localhost:6379".

Can you please help me ?

Thanks in advance,

Redis TTL and MaxInactiveInterval issue

SessionManager.java

int timeout = getContextIns().getSessionTimeout() * 60;`
int sessionTimeout = (session == null) ? 0 : session.getMaxInactiveInterval() * 60;

web.xml

<session-config>
    <session-timeout>30</session-timeout>
</session-config>

After session first created, redis TTL shows 108000, why isn't 1800?

Remove * 60 may fix the issue.

Test env is tomcat 7 and JDK 7.

logout defautl ttl 10

The default value of ttl, which changes to redis when you log out, is 10. Is there a way to modify this value?

Can a tomcat container get in a bad state somehow?

We are using the following in our tomcat.xml.

    <Valve className="tomcat.request.session.redis.SessionHandlerValve" asyncSupported="true"/>
    <Manager className="tomcat.request.session.redis.SessionManager" />

We are experiencing a problem where a given tomcat container or several tomcat containers can get in a bad state somehow where seemingly they are retrieving bad and/or incomplete session data from redis. It seems to happen after a container is bounced.

Presumably, containers should be able to be bounced and they should be able to start processing requests for a given jsessionid immediately. However, it seems that the problem we are having is that once a given container is bounced, it's not possible to get back in a "good" state, where it can successfully process requests for a given jsessionid.

Any thoughts on this? Has anyone ever reported anything like this? Thanks in advance!

Can you help me?

Can't connect to alive master.

A redis cluster with 3 nodes(node A,nodeB,nodeC) and slave-serve-stale-data is set to 'no'. I initialized port 7000 as master on echo node at first and 7001-7002 as replicas slave. I configured RedisDataCache.properties as redis.hosts=192.168.168.7:7000, 192.168.168.8:7000, 192.168.168.9:7000. Everything goes OK.
But when I kill redis instance or reboot node to simulate server fault, the cluster status has changed, for example 92.168.168.7:7000 became slave not master any more while 192.168.168.8:7000 or 192.168.168.9:7000 still act as master. The tomcat report Exception says like:
type Exception report message CLUSTERDOWN The cluster is down description The server encountered an internal error that prevented it from fulfilling this request. exception redis.clients.jedis.exceptions.JedisClusterException: CLUSTERDOWN The cluster is down redis.clients.jedis.Protocol.processError(Protocol.java:115)

How to deal with this issue? Thanks.

For this error, I am using the following library file:

tomcat-cluster-redis-session-manager-3.0
jedis-2.9.0.jar

I tried to use the latest jars but still encountered the same issue. Currently my project is using

Apache Tomcat/9.0.19
AWS Correto 11 to build war file and run the tomcat server.

Able to assist me?

Thank you.

use jdk1.6 error

JDK1.6 must be used for project reasons。java.lang.UnsupportedClassVersionError: tomcat/request/session/redis/SessionHandlerValve : Unsupported major.minor version 51.0

When Redis goes down, the web app always fails returning failure

Hi,

I was just checking how the server will behave when the redis server is down. Should it continue to accept web requests.

However I noted that, once the redis server is down, all the web requests are returned 500...
Is there something I should do.

Error

Error occured while saving the session object in data cache.. -tomcat.request.session.redis.SessionManager
java.io.NotSerializableException: java.lang.Object

Session destruction

Do you need to do this when session is destroyed and call the remove method in session manager when session is destroyed? Or in other ways

Session timeout default to 1800s ,can not be lower

When I set session timeout with
<session-config> <session-timeout>2</session-timeout> </session-config>
I find that timeout can not be set lower than 30 minutes(1800 s).
so is the redis TTl(1800s).
Is that a bug ? Or just something else?
Thanks.

RedisCacheUtil methods close jedis connection incorrect

	public byte[] set(String key, byte[] value) {
		int tries = 0;
		boolean sucess = false;
		String retVal = null;
		do {
			tries++;
			try {
				Jedis jedis = pool.getResource();
				retVal = jedis.set(key.getBytes(), value);
				jedis.close();
				sucess = true;
			} catch (JedisConnectionException ex) {
				log.error(RedisConstants.CONN_FAILED_RETRY_MSG + tries);
				if (tries == NUM_RETRIES)
					throw ex;
			}
		} while (!sucess && tries <= NUM_RETRIES);
		return (retVal != null) ? retVal.getBytes() : null;
	}

try catch体内调用jedis.close(); 很可能导致不能正常关闭，是否在finally内调用?
bug现象为tomcat 产生很多CLOSE_WAIT的tcp连接，怀疑和这段代码有关
使用的是redis单点服务，redis集群则没有这种情况

session.invalidate is not working

session invalidate does not work after applying redis-session lib.
and then also JSESSION ID is not change.

I'm using Tomcat 8.5.40 and

here ls my code.

HttpSession session = request.getSession();
session.removeAttribute("logonSessData");
session.invalidate();
