blocks|key|682441|text|这也是我遇到的一个问题--如果你在vhost中定义了你的平衡器，那么它似乎就像文档中描述的那样使用了stickysession。然而，如果你在vhost之外定义一个平衡器，那么粘滞会话就会丢失，所以你必须在平衡器本身内使用ProxySet来设置它。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|682442|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

This is a problem I have come across too - if you define your balancer within a vhost then it seems to use the stickysession as documented. However if you are defining a balancer outside of the vhost its used in then the stickysession gets lost so you have to set it using ProxySet within the balancer itself.

blocks|key|898984|text|我认为你的问题是，你在使用mybalancer的时候，你必须使用balancer：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|898985|ProxyPass+/myapp/+balancer://mybalancer/+stickysession=JSESSIONID|code-block|syntax|javascript|898986|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

I think your problem is that you are using mybalancer where you have tu use balancer:

<pre><code>ProxyPass /myapp/ balancer://mybalancer/ stickysession=JSESSIONID
</code></pre>

Pls try this, I'm sure this will work for you.

Step-1: Add below code in httpd.conf:

<pre><code>&lt;Proxy balancer://mycluster&gt;
BalancerMember http://&lt;NODE1&gt;/&lt;APP&gt;/ route=jvm1 
BalancerMember http://&lt;NODE2&gt;/&lt;APP&gt;/ route=jvm2
ProxySet lbmethod=bytraffic
ProxySet stickysession=JSESSIONID
&lt;/Proxy&gt;

ProxyPass /&lt;APP&gt;/ balancer://mycluster/ 
ProxyPassReverse /&lt;APP&gt;/ balancer://mycluster/
</code></pre>

Step-2: Add below code in server.conf:

<pre><code>a) &lt;NODE1&gt;
&lt;Engine name="Catalina" defaultHost="localhost" jvmRoute="jvm1"&gt; 
b) &lt;NODE2&gt;
&lt;Engine name="Catalina" defaultHost="localhost" jvmRoute="jvm2"&gt;
</code></pre>

None of the above solutions worked for me, but I found it in MOTECH project documentation here: <a href="http://docs.motechproject.org/en/latest/deployment/sticky_session_apache.html" rel="nofollow noreferrer">http://docs.motechproject.org/en/latest/deployment/sticky_session_apache.html</a>

This config works for me (on Apache 2.4.41):

<pre><code>&lt;VirtualHost *:80&gt;
 (...)
 Header add Set-Cookie "ROUTEID=.%{BALANCER_WORKER_ROUTE}e; path=/" env=BALANCER_ROUTE_CHANGED
 (...)
 &lt;Proxy balancer://mycluster&gt;
 (...)
 BalancerMember http://10.20.30.40:8080 route=backend-1 enablereuse=On
 BalancerMember http://10.20.30.41:8080 route=backend-2 enablereuse=On

 ProxySet lbmethod=bytraffic
 ProxySet stickysession=ROUTEID
 (...)
 &lt;/Proxy&gt;

 ProxyPass / balancer://mycluster/
 ProxyPassReverse / balancer://mycluster/
 (...)
&lt;/VirtualHost&gt;
</code></pre>

I am using apache web server as a load balancer for two tomcat instances behind apache. When the first request goes to node A and second request from the same client goes to node B, i cant access session variables within node A. It's obvious. I surfed in the internet and found that enabling sticky sessions would help. But all the tutorials for enabling the sticky sessions in apache look confusing. Is there any simple step-by-step tutorial for this? Please help.

Code fragment from comment:

<pre><code>ProxyPass /balancer-manager ! 
ProxyPass /balancer://mycluster/ stickysession=JSESSIONID 
ProxyPassReverse /balancer://mycluster/ 
&lt;Proxy balancer://mycluster&gt;; 
 BalancerMember ajp://localhost:9001/ route=NodeA1000 retry=10 
 BalancerMember ajp://localhost:9002/ route=NodeB1000 retry=10 
&lt;/Proxy&gt; 
</code></pre>

负载均衡

服务器

我使用apache web服务器作为apache后面两个tomcat实例的负载均衡器。当第一个请求发送到节点A，第二个请求发送到节点B时，我无法访问节点A中的会话变量。这很明显。我在网上冲浪，发现启用粘滞会话会有所帮助。但是，在apache中启用粘性会话的所有教程看起来都令人困惑。有没有什么简单的一步步教程来解决这个问...
