tomcat6 - Tomcat到底是怎么跑完CATALINA_HOME和CATALINA_BASE的

Question

我找不到与此相关的文档。经过一些谷歌搜索后，我发现 bin、conf、logs、temp、webapps、work 是应该存在于 CATALINA_BASE 中的目录。

temp、logs、webapps、bin 和 work 我在理解上没有任何困难。

bin 我想只是另一个 bin 文件夹，如果由于某种原因 CATALINA_HOME 和 CATALINA_BASE 都在 PATH 中，那么两个文件夹中的脚本都可以执行。

但是 conf 呢？如果设置了CATALINA_BASE，CATALINA_HOME/conf的内容会被完全忽略吗？假设我只需要自定义几个配置文件 pr。 CATALINA_BASE，我是否仍需要在 CATALINA_BASE/conf 中保留一套完整的配置文件，或者是否可以在 CATALINA_HOME/conf 中保留标准配置文件共享？

对于 CATALINA_BASE/lib 也是如此……这会作为“全局”lib 文件夹 pr 工作吗？实例？

您可以在 Tomcat 文档中找到答案:

Advanced Configuration - Multiple Tomcat Instances

In many circumstances, it is desirable to have a single copy of a Tomcat binary distribution shared among multiple users on the same server. To make this possible, you can set the $CATALINA_BASE environment variable to the directory that contains the files for your 'personal' Tomcat instance.

When you use $CATALINA_BASE, Tomcat will calculate all relative references for files in the following directories based on the value of $CATALINA_BASE instead of $CATALINA_HOME:

• bin - Only setenv.sh (*nix), setenv.bat (windows) and tomcat-juli.jar

• conf - Server configuration files (including server.xml)

• logs - Log and output files

• webapps - Automatically loaded web applications

• work - Temporary working directories for web applications

• temp - Directory used by the JVM for temporary files (java.io.tmpdir)

Note that by default Tomcat will first try to load classes and JARs from $CATALINA_BASE/lib and then $CATALINA_HOME/lib. You can place instance specific JARs and classes (e.g. JDBC drivers) in $CATALINA_BASE/lib whilst keeping the standard Tomcat JARs in $CATALINA_HOME/lib.

If you do not set $CATALINA_BASE, $CATALINA_BASE will default to the same value as $CATALINA_HOME, which means that the same directory is used for all relative path resolutions.
