Apache 找不到名为'；ajp13#U工人'；

我有一个带有Apache2+Tomcat9的新Debian10服务器。由于内部服务器错误，我无法运行JSF页面。我认为错误在ApacheTomcat连接器（libapache2 mod jk）中

我使用openjdkv。11，我还使用ApacheTomcat本机库[1.2.23]，使用APR版本[1.7.0]。 Tomcat定期运行，Apache也是如此

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=/

Apache似乎找不到“ajp13_worker”worker

为什么?

谢谢。

您必须在apache文件中定义JK选项，在virtualhost之前，而不是在中。例如：

JkWorkersFile /etc/libapache2-mod-jk/workers.properties
JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories
JkLogFile ${APACHE_LOG_DIR}/mod_jk.log
JkLogLevel info                
JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "

---

jkworkers文件是必需的，其他文件是可选的。

您必须将JK配置文件从

httpd JK.conf

重命名为

JK.conf

。 这对我很有用：

$ 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

---

我遇到了这个问题。通过分析Apache日志（error.log），我注意到没有加载文件/etc/apache2/mods available/httpd-jk.conf（来自/etc/libapache2 mod jk/httpd jk.conf的符号链接），因为Apache修复了日志文件的默认名称（JkLogFile指令）。

---

然后只需将httpd-jk.conf文件复制到/etc/apache2/conf下即可，然后将此副本的符号链接设置为目标/etc/apache2/conf启用，一切正常。

sudo apache2ctl configtest AH00526:etc/apache2/sites enabled/example.com-le-ssl.conf的第1行出现语法错误：JkWorkersFile仅允许一次操作'configtest'失败。Apache错误日志可能包含更多信息。很抱歉，上面的评论是@Bernat针对下面的解决方案提出的，但您的解决方案没有解决问题，仍在获取无法找到工作程序名称UDO apache2ctl configtest AH00526:/etc/apache2/sites enabled/example.com-le-ssl.conf的第1行上的语法错误：只有在操作“configtest”失败时才允许jkWorkers文件。Apache错误日志可能包含更多信息。您能否分步解决此问题？
