Question

我正在尝试配置代理服务器以在我的两个应用程序服务器之间对HTTP请求进行负载平衡。

我已经实现了使用循环方法路由请求。

现在，我想知道如何配置启用会话亲和性，因为我在登录后面临问题，错误 - 会话终止。

提前致谢。如果需要任何进一步的信息，请告诉我。

Answer 1

最首选的解决方案是使用 Websphere插件进行负载平衡。 IBM或其他供应商提供的许多产品可用作反向代理/负载均衡器，如IBM ODR，IBM Websphere Proxy Server或IBM Edge Load Balancer e.t.c。

但是，如果由于某种原因您无法使用此类内容，则可以使用Apache 2.X和许多独立的Websphere应用程序服务器（在本例中为WAS1和WAS2）执行以下步骤：

声明代理均衡器，如下所示：

<Proxy balancer://mylb/>
    BalancerMember http://<WAS1_hostname>:9080 route=WAS1 retry=120 status=+E
    BalancerMember http://<WAS2_hostname>:9080 route=WAS2 retry=120 status=+E
    ProxySet stickysession=JSESSIONID
</Proxy>

在每个WAS控制台中，转到应用程序服务器＆gt; server_name＆gt; Web容器＆gt;自定义属性，设置以下属性，然后重新启动服务器：

HttpSessionCloneId = WAS1（即等于上面的路线值）

CloneSeparator = 。

然后根据您的偏好使用平衡器，例如：

<Location />
        ProxyPass balancer://mylb/mycontextpath/
        ProxyPassReverse balancer://mylb/mycontextpath/
        ProxyPassReverseCookiePath /mycontextpath /
</Location>

这不是一个官方支持的解决方案（你只需要带有mod_proxy和mod_proxy_balancer的apache http服务器），但它应该可以工作。
