什么在Tomcat 6配置文件中设置$ {catalina.home}？

Question

我正在尝试调整一些旧的构建脚本来运行Tomcat 6的RPM安装,我遇到了以下问题:

java.lang.IllegalArgumentException: Document base /var/lib/tomcat6/webapps/host-manager does not exist or is not a readable directory

这不足为奇,因为Tomcat不在/var/lib/tomcat6,它在/usr/share/tomcat6.当我查找它可能来自哪里时,我发现的所有内容都在以下文件中host-manager.xml:

<Context docBase="${catalina.home}/webapps/host-manager"
     privileged="true" antiResourceLocking="false" antiJARLocking="false">

</Context>

现在,我已经$CATALINA_HOME设置了/usr/share/tomcat6它应该是,并且/var/lib在我的网络应用程序(包括配置)或我的Tomcat 6安装中没有任何引用,据我所知.那是什么${catalina.home},以及如何/var/lib/tomcat6取而代之？

查看您的${TOMCAT_HOME}/bin/catalina.sh文件 - 向下滚动到开始部分 - 从CATALINA_HOMEenv变量设置catalina.home系统属性:

-Dcatalina.home=\"$CATALINA_HOME\"

现在,为什么这与你的CATALINA_HOMEenv变量设置不同 - 你需要检查你的tomcat服务器是如何启动的,特别是在从它启动的进程/上下文中设置的环境变量.

那么你是如何开始你的tomcat实例的呢？
