带有 AJP 连接器的 Tomcat 管理器出现 404

我正在尝试使用 Apache mod_jk、SSL 和 AJP 连接器在 CentOS 6 上配置 Tomcat 7。

Apache下安装JK模块：

$ sudo httpd -M | grep jk
jk_module (shared)
Syntax OK

Tomcat 配置 AJP 连接器如下：

<?xml version='1.0' encoding='utf-8'?>
<Server port="8005" shutdown="SHUTDOWN">
  <Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" />
  <Listener className="org.apache.catalina.core.JasperListener" />
  <Listener className="org.apache.catalina.core.JreMemoryLeakPreventionListener" />
  <Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" />
  <Listener className="org.apache.catalina.core.ThreadLocalLeakPreventionListener" />
  <GlobalNamingResources>
    <Resource name="UserDatabase" auth="Container"
              type="org.apache.catalina.UserDatabase"
              description="User database that can be updated and saved"
              factory="org.apache.catalina.users.MemoryUserDatabaseFactory"
              pathname="conf/tomcat-users.xml" />
  </GlobalNamingResources>
  <Service name="Catalina">
    <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" packetSize="65536" />
    <Engine name="Catalina" defaultHost="localhost">
      <Realm className="org.apache.catalina.realm.LockOutRealm">
        <Realm className="org.apache.catalina.realm.UserDatabaseRealm"
               resourceName="UserDatabase"/>
      </Realm>
      <Host name="localhost"  appBase="webapps"
            unpackWARs="true" autoDeploy="true">
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
               prefix="localhost_access_log." suffix=".txt"
               pattern="%h %l %u %t &quot;%r&quot; %s %b" />
      </Host>
    </Engine>
  </Service>
</Server>

worker.properties文件配置如下：

worker.list=default,lb,jk-status
worker.default.type=ajp13
worker.default.host=x.x.x.x
worker.default.port=8009
worker.lb.type=lb
worker.lb.balance_workers=default
worker.jk-status.type=status

Apache 配置为通过虚拟主机为 Tomcat webapps 提供服务，如下所示：

LoadModule jk_module modules/mod_jk.so

JkWorkersFile /etc/httpd/conf/workers.properties
JkShmFile /var/log/httpd/mod_jk.shm
JkLogFile /var/log/httpd/mod_jk.log
JkLogLevel info
JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "
JkOptions +RejectUnsafeURI +ForwardKeySize +ForwardURICompat -ForwardDirectories
JkRequestLogFormat "%w %V %T"
JkMountCopy All

<VirtualHost x.x.x.x:80>
  ServerAdmin [email protected]
  ServerName my.domain.com
  ServerAlias www.my.domain.com

  # Always redirect to SSL
  RewriteEngine on
  ReWriteCond %{SERVER_PORT} !^443$
  RewriteRule ^/(.*) https://%{HTTP_HOST}/$1 [NC,R,L]
</VirtualHost>

<VirtualHost x.x.x.x:443>
  ServerAdmin [email protected]
  ServerName my.domain.com:443
  ServerAlias www.my.domain.com

  ErrorLog /var/log/httpd/ssl_my.domain.com_error_log
  LogFormat "%t %h %{SSL_PROTOCOL}x %{SSL_CIPHER}x \"%r\" %>s %b" ssl_log
  CustomLog /var/log/httpd/ssl_my.domain.com_access_log ssl_log

  SSLEngine on
  SSLCertificateFile /etc/pki/tls/certs/my.domain.com.crt
  SSLCertificateKeyFile /etc/pki/tls/private/my.domain.com.key
  SSLCertificateChainFile /etc/pki/tls/certs/tw-chain.crt

  JkMountCopy On
  JkMount /manager default
  JkMount /manager/* default
</VirtualHost>

Tomcat 和管理器应用程序已启动并运行，没有明显错误：

然而，当我尝试加载管理器应用程序时https://xxxx/manager，我收到 404 错误。我知道请求已到达 Tomcat，因为 URL 重定向到 /manager/html，并且我收到 Tomcat 404 而不是 Apache 404。Apache 日志显示请求：

[17/Sep/2014:15:44:05 -0400] x.x.x.x TLSv1.2 AES256-SHA256 "GET /manager/html HTTP/1.1" 404 975

mod_jk 的日志也显示了请求：

[Wed Sep 17 15:43:54 2014] [22722:140360872835040] [info] init_jk::mod_jk.c (3383): mod_jk/1.2.40 initialized

这个问题让我很困惑——一切似乎都正常运转，但通信却在某个地方中断了。任何见解都将不胜感激，谢谢！

问题原来是 APR 库构建失败。我使用 Ansible 部署 Tomcat，“shell”命令中一个明显的错误导致 APR 配置悄无声息地失败。

有关 Ansible 的此问题的详细信息请参见此处：Ansible playbook 尝试使用复杂的开关运行 make 和 configure 时不起作用
