问题描述
我已经使用yum配置工具的CentOS 5安装Tomcat5的。
我的Java Web应用程序需要Java 1.6没有错误运行。然而，我的tomcat安装出现使用Java 1.4是。当我浏览到Tomcat管理器页面这证实：
I have installed Tomcat5 on CentOS 5 using the yum configuration tool. My java web application requires java 1.6 to run without errors. However, my tomcat install appears to be using java 1.4. This is confirmed when I navigate to the tomcat manager page:
Tomcat Version JVM Version
Apache Tomcat/5.5.23 1.4.2
在Linux提示符处，当我执行命令：
At the linux prompt, when I execute the command:
java -version
它揭示了：
java version "1.6.0"
OpenJDK Runtime Environment (build 1.6.0-b09)
OpenJDK 64-Bit Server VM (build 1.6.0-b09, mixed mode)
我modifyied / etc / profile文件和设置JAVA_HOME，JRE_HOME和CATALINA_HOME。当我执行 TOMCAT5版本下面的输出结果：
Using CATALINA_BASE: /usr/share/tomcat5
Using CATALINA_HOME: /usr/share/tomcat5
Using CATALINA_TMPDIR: /usr/share/tomcat5/temp
Using JRE_HOME: /usr/lib/jvm/jre-1.6.0

然而，当我启动tomcat并查看服务器信息在JVM仍说：
However, when I start tomcat and view the server information the JVM still says:

任何帮助是AP preciated。
Any help is appreciated.

推荐答案
它看起来像很多人（包括在的CentOS 和其他平台）有使用Tomcat的百胜安装的版本麻烦。我尝试安装它自己，倾向于同意 - 它看起来pretty凌乱
It looks like many people (both on CentOS and other platforms) have trouble with the yum-installed version of tomcat. I tried installing it myself, and tend to agree - it looks pretty messy.
与其他人一样在上面的链接，我会建议删除yum的版本，并从 http://tomcat.apache.org直接下载压缩包版本/ 。我用这个方法对我所有的Tomcat的安装（相当频繁），并有几个问题，这一做法。
Like others in the above links, I would recommend removing the yum version and downloading the tarball version straight from http://tomcat.apache.org/. I use this method for all of my tomcat installations (quite frequent), and have had few problems with this approach.
您可以提取压缩包，无论你认为适合您的系统（也许 /选择），并使用 startup.sh <启动它/ code>在目录。它应该服从的环境变量比百胜的版本更好，但你也可以设置它们在与应用程序提供的属性文件或脚本中的一个。
You can extract the tarball wherever you deem appropriate for your system (perhaps /opt), and start it up using the startup.sh script in the bin/ directory. It should obey environment variables better than the yum version, but you can also set them in one of the properties files or scripts delivered with the application.
