【问题描述】：

我已经创建了两个 tomcat 实例并更改了 AJP 端口，如下所示。

<Connector port="1983" protocol="AJP/1.3" redirectPort="8553" address="0.0.0.0" />

然后我编辑了worker.properties并添加了这个端口，如下所示。

worker.app2Worker.type=ajp13
worker.app2Worker.host=serapp.abcapp.com
worker.app2Worker.port=1983

我已经修改了 ssl.conf 和这个 worker。但我得到了以下错误。

网络服务器：Apache 7
应用服务器：Tomcat 8

你能告诉我这里出了什么问题吗？

【问题讨论】：

tomcat 是否启动并监听正确的端口？
是的。我可以从 Apache Web 服务器远程登录到该端口

标签： apache tomcat mod-jk

【解决方案1】：

对我来说是 selinux 阻止了连接，需要调整策略：https://serverfault.com/questions/563872/selinux-allow-httpd-to-connect-to-a-specific-port

【解决方案2】：

请找到我对上述问题的调查和回答：

factory="org.apache.tomcat.jdbc.pool.DataSourceFactory"
maxActive="100"
maxIdle="20"
maxWait="10000"
validationInterval="60000"
minEvictableIdleTimeMillis="600000"
removeAbandoned="true"
removeAbandonedTimeout="600"
logAbandoned="true"
timeBetweenEvictionRunsMillis="60000"

添加这些参数后Tomcat需要重启

解决了我的问题希望对你有帮助:)
