apache - 找不到名称为 'ajp13_worker' 的 worker

Question

我有一个带有 Apache 2 + Tomcat 9 的新 Debian 10 服务器。由于内部服务器错误，我无法运行 JSF 页面。我认为错误出在 Apache Tomcat 连接器 (libapache2-mod-jk) 中..

我使用 OpenJDK v. 11，我还使用使用 APR 版本 [1.7.0] 的 Apache Tomcat Native 库 [1.2.23]。
Tomcat 和 Apache 定期运行。

这是我的 workers.properties 文件:

        # workers.properties -
    #
    # This file is a simplified version of the workers.properties supplied
    # with the upstream sources. The jni inprocess worker (not build in the
    # debian package) section and the ajp12 (deprecated) section are removed.
    #
    # As a general note, the characters $( and ) are used internally to define
    # macros. Do not use them in your own configuration!!!
    #
    # Whenever you see a set of lines such as:
    # x=value
    # y=$(x)\something
    #
    # the final value for y will be value\something
    #
    # Normaly all you will need to do is un-comment and modify the first three
    # properties, i.e. workers.tomcat_home, workers.java_home and ps.
    # Most of the configuration is derived from these.
    #
    # When you are done updating workers.tomcat_home, workers.java_home and ps
    # you should have 3 workers configured:
    #
    # - An ajp13 worker that connects to localhost:8009
    # - A load balancer worker
    #
    #

    # OPTIONS ( very important for jni mode )

    #
    # workers.tomcat_home should point to the location where you
    # installed tomcat. This is where you have your conf, webapps and lib
    # directories.
    #
    workers.tomcat_home=/usr/share/tomcat9

    #
    # workers.java_home should point to your Java installation. Normally
    # you should have a bin and lib directories beneath it.
    #

    workers.java_home=/usr/lib/jvm/java-11-openjdk-amd64

    #
    # You should configure your environment slash... ps=\ on NT and / on UNIX
    # and maybe something different elsewhere.
    #
    ps=/

我的 Apache 是:

        <VirtualHost *:80>
    DocumentRoot "/var/www/vhosts/www.mydomain.com/ROOT"
    ServerName www.mydomain.com
    ServerAdmin info@mydomain.com

    JkMount /* ajp13_worker

    <Directory "/var/www/vhosts/www.mydomain.com/ROOT">
    allow from all
    Options None
    Require all granted
    </Directory>
    </VirtualHost>

似乎 Apache 找不到“ajp13_worker” worker ..

为什么？

谢谢。

您必须从 httpd-jk.conf 重命名 JK 配置文件至 jk.conf .
这对我有用:

$ sudo a2dismod jk
$ sudo mv /etc/apache2/mods-available/httpd-jk.conf /etc/apache2/mods-available/jk.conf
$ cd /etc/libapache2-mod-jk/
$ sudo ln -f -s ../apache2/mods-available/jk.conf httpd-jk.conf
$ sudo a2enmod jk
$ sudo apache2ctl configtest
$ sudo systemctl restart apache2
