我有一个 Tomcat 服务器正在监听 10881 AJP 端口。我通过 netstat 确认了这一点：
tcp 0 0 0.0.0.0:10881 0.0.0.0:* LISTEN 2297/java
这是Tomcat server.xml文件的配置：
<Connector port="10881" protocol="AJP/1.3" redirectPort="8443" URIEncoding="UTF-8" />
<Engine name="Catalina" defaultHost="localhost" jvmRoute="portal">
这是 worker.properties 文件：
worker.list=portal,jkstatus
#liferay portal
worker.portal.type=ajp13
worker.portal.host=localhost
worker.portal.port=10881
#jk status
worker.jkstatus.type=status
这是 VirtualHost 配置文件：
<VirtualHost *:80>
DocumentRoot /var/www/html/portal
ServerName portal.local
ErrorLog "|/usr/sbin/rotatelogs /var/log/httpd/portal.local-error-log.%Y-%m-%d-%H_%M_%S 10M"
CustomLog "|/usr/sbin/rotatelogs /var/log/httpd/portal.local-access-log.%Y-%m-%d-%H_%M_%S 10M" combined
#JkMount features
JkMount /* portal
<Directory />
Options +FollowSymLinks
Order allow,deny
Allow from all
</Directory>
</VirtualHost>
当我尝试进入 portal.local 时，它返回 503 错误代码。我查看了 mod_jk.log 文件，这是其内容：

我可以看到一个 111 错误，表示端口可能未在监听，但正如我所写，端口确实在监听。我不知道问题出在哪里。
答案1
问题出在 mod_jk 版本上。我使用最新版本的 Tomcat Connectors（1.2.40）编译了它。然后我尝试使用较低版本的 TC（1.2.35）进行编译，并且成功了。
