我有一台带有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。我认为错误是在Apache Tomcat连接器（libapache2-mod-jk）中。.]
我使用OpenJDK v。11，我也使用APR版本[1.7.0]的Apache Tomcat Native库[1.2.23]。Tomcat正常运行，Apache也正常运行。
这是我的worker.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 [email protected]
JkMount /* ajp13_worker
JkLogLevel debug
<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。
您必须在apache文件中的virtualhost之前而不是在其中定义JK选项。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] "
JKWorkersFile是必需的，其他是可选的。
