![mod_jk 无法连接 tomcat9](https://linux22.com/image/751493/mod_jk%20%E6%97%A0%E6%B3%95%E8%BF%9E%E6%8E%A5%20tomcat9.png)
解压 tomcat.apache.org 上提供的 tomcat9 包后,将 mod_jk 配置为:
workers.tomcat_home=/opt/apache-tomcat-9.0.34
workers.java_home=/opt/jdk-13
ps=/
worker.list=ajp13_worker
worker.ajp13_worker.port=8009
worker.ajp13_worker.host=localhost
worker.ajp13_worker.type=ajp13
当我将 WAR 部署到 webapps 目录并尝试访问它时,浏览器显示此错误:
在 mod_jk 日志中,我得到了这个:

我的server.xml
文件已经取消注释此部分:
<!-- Define an AJP 1.3 Connector on port 8009 -->
<Connector protocol="AJP/1.3"
address="::1"
port="8009"
redirectPort="8443" />
如果我尝试使用类似http://mydomain:8080/app
名为的webapp的某个id进行访问app
,则可以正常工作。但如果没有:8080
,则应该通过mod_jk进行访问,我收到了错误。
谁能告诉我这里出了什么问题?
答案1
添加secretRequired="false"
到其中<Connector>
即可server.xml
为我修复该问题。
<!-- Define an AJP 1.3 Connector on port 8009 -->
<Connector protocol="AJP/1.3"
port="8009"
redirectPort="8443"
secretRequired="false" />
答案2
您正在尝试通过 IPv4 进行连接(127.0.0.1 是赠品),但您告诉 Tomcat 在 IPv6 本地主机(::1)上监听。
也许告诉 Tomcat 也使用 IPv4(tomcat 绑定到 ipv4)。
答案3
我使用了以下内容:
setsebool -P httpd_can_network_connect=1
您可以使用此命令来检查其是否设置正确:
getsebool -a | grep httpd
您应该看到:
httpd_can_network_connect --> on
