Linux Tomcat 6.0安装配置实践总结
原文： http://www.cnblogs.com/kerrycode/p/3588816.html系统环境： Red Hat Enterprise Linux Server> Tomcat下载
从官方网站 http://tomcat.apache.org/下载你需要的Tomcat版本，目前Tomcat主要版本有Tomcat 6.0、Tomcat 7.0、Tomcat 8.0三个版本，下面我们以6.0(6.0.39)版本为例， 下载URL地址：http://tomcat.apache.org/download-60.cgi ，如果你需要下载Tomcat 6.0下的其它版本，点击链接地址“Archives“ http://archive.apache.org/dist/tomcat/tomcat-6/ 即可查看到你需要的版本。
Tomcat安装
Step 1：安装配置JDK
关于JDK的安装配置细节可以参考我以前的博客lRedhat Linux安装JDK 1.7，JDK最好选择合适的版本，这里我为了方便省事，就安装了JDK1.7.
1: # chmod +x jdk-7u25-linux-x64.rpm
2:
3: # rpm -ivh jdk-7u25-linux-x64.rpm
4: Preparing... ###########################################
5: 1:jdk ###########################################
6: Unpacking JAR files...
7: rt.jar...
8: jsse.jar...
9: charsets.jar...
10: tools.jar...
11: localedata.jar...
12: # cd /usr/java/
配置环境变量，在etc/profile文件下添加
export JAVA_HOME=/usr/java/jdk1.7.0_25
export> export PATH=$JAVA_HOME/bin:$PATH
1: # vi /etc/profile
2: # source /etc/profile --生效修改配置信息
3:
4: # echo $JAVA_HOME
5: /usr/java/jdk1.7.0_25
6: # echo $CLASSPATH
7: /usr/java/jdk1.7.0_25/lib
8: # java -version
9: java version "1.7.0_25"
10: Java(TM) SE Runtime Environment (build 1.7.0_25-b15)
11: Java HotSpot(TM) 64-Bit Server VM (build 23.25-b01, mixed mode)
12: #
Step 2：安装Tomcat
1: #tar zxvf apach-tomcat-6.0.16.tar.gz
2:
3: #mkdir /usr/local/tomcat
4:
5: # mv apache-tomcat-6.0.39 /usr/local/ tomcat
6:
7:
8: # vi /etc/profile
9:
10: export TOMCAT_HOME=/usr/local/tomcat
11:
12:
13: # source /etc/profile
14: # echo $TOMCAT_HOME
15: /usr/local/tomcat
16:
17:
18: # pwd
19: /usr/local/tomcat/apache-tomcat-6.0.39/bin
20: # ./startup.sh
21: Using CATALINA_BASE: /usr/local/tomcat/apache-tomcat-6.0.39
22: Using CATALINA_HOME: /usr/local/tomcat/apache-tomcat-6.0.39
23: Using CATALINA_TMPDIR: /usr/local/tomcat/apache-tomcat-6.0.39/temp
24: Using JRE_HOME: /usr/java/jdk1.7.0_25
25: Using CLASSPATH: /usr/local/tomcat/apache-tomcat-6.0.39/bin/bootstrap.jar
如果需要指定Tomcat在某个账号下运行或管理，则可以通过下面脚本：例如，我要创建一个tomcat的账号
1: # groupadd tomcat
2:
3: # useradd -g tomcat -d /home/tomcat -u 502 tomcat
4:
5: Creating mailbox file: File exists
6:
7: # chown -Rf tomcat.tomcat /usr/local/tomcat/
8:
9: #passwd tomcat
10:
11: Changing password for user tomcat.
12:
13: New UNIX password:
14:
15: Retype new UNIX password:
16:
17: passwd: all authentication tokens updated successfully.
在浏览器里面输入http://localhost:8080/（默认端口为8080,可以修改该端口号） 验证Tomcat是否安装成功，如果安装成功，则会看到Tomcat的index.jsp并证明Tomcat启动成功了
Tomcat配置
关于Tomcat的目录结构，可以参考下面简单的描述，
# ls
bin lib logs > conf LICENSE NOTICE RUNNING.txt webapps
主目录下面有bin、lib等目录
bin 存放Tomcat启动、停止服务程序以及一些其他脚本程序
lib 存放Tomcat运行需要的jar包
log 存放Tomcat运行的相关日志文件
conf 存放Tomcat配置文件。例如server.xml 、 web.xml等
temp 存放Tomcat运行的临时文件。
webapps Web应用的发布目录，默认情况下把Web应用文件放于此目录。
work Tomcat的工作目录，默认情况下把编译JSP文件生成的servlet类文件放于此目录下
1：启动Tomcat服务
1: # ./startup.sh
2:
3: Using CATALINA_BASE: /usr/local/tomcat/apache-tomcat-6.0.39
4:
5: Using CATALINA_HOME: /usr/local/tomcat/apache-tomcat-6.0.39
6:
7: Using CATALINA_TMPDIR: /usr/local/tomcat/apache-tomcat-6.0.39/temp
8:
9: Using JRE_HOME: /usr/java/jdk1.7.0_25
10:
11: Using CLASSPATH: /usr/local/tomcat/apache-tomcat-6.0.39/bin/bootstrap.jar
2：关闭Tomcat服务
1: # ./shutdown.sh
2:
3: Using CATALINA_BASE: /usr/local/tomcat/apache-tomcat-6.0.39
4:
5: Using CATALINA_HOME: /usr/local/tomcat/apache-tomcat-6.0.39
6:
7: Using CATALINA_TMPDIR: /usr/local/tomcat/apache-tomcat-6.0.39/temp
8:
9: Using JRE_HOME: /usr/java/jdk1.7.0_25
10:
11: Using CLASSPATH: /usr/local/tomcat/apache-tomcat-6.0.39/bin/bootstrap.jar
12:
13: #
3：查看Tomcat版本
有时候，如果当你接手去管理Tomcat,可能你要了解一下Tomcat的版本信息，以及配置，那么怎么查看呢，去Tomcat的主目录下的bin目录下，执行version.sh,你就能查看到很多详细信息。
1: # ./version.sh
2:
3: Using CATALINA_BASE: /usr/local/tomcat/apache-tomcat-6.0.39
4:
5: Using CATALINA_HOME: /usr/local/tomcat/apache-tomcat-6.0.39
6:
7: Using CATALINA_TMPDIR: /usr/local/tomcat/apache-tomcat-6.0.39/temp
8:
9: Using JRE_HOME: /usr/java/jdk1.7.0_25
10:
11: Using CLASSPATH: /usr/local/tomcat/apache-tomcat-6.0.39/bin/bootstrap.jar
12:
13: Server version: Apache Tomcat/6.0.39
14:
15: Server built: Jan 27 2014 10:40:33
16:
17: Server number: 6.0.39.0
18:
19: OS Name: Linux
20:
21: OS Version: 2.6.18-274.el5
22:
23: Architecture: amd64
24:
25: JVM Version: 1.7.0_25-b15
26:
27: JVM Vendor: Oracle Corporation
28:
4：设置管理密码
如果你要进入Tomcat的管理页面：http://localhost:8080/manager/html ，这时会弹出下面认证界面，需要你输入用户名和密码，如果你没有配置过或者你忘了用户名、密码，那么应该找那个配置文件呢？其实你都可以通过配置文件tomcat-users.xml 来解决

1: # more tomcat-users.xml
2:
3: xml version='1.0' encoding='utf-8'?>

修改配置文件前，要养成首先备份一份配置文件的习惯，以防需要回滚到最初设置时，忘了自己修改过哪些配置。一般建议源文件+日期+bak
# cp tomcat-users.xml tomcat-users.xml.20130308.bak
# vi tomcat-users.xml
修改了配置信息后，一般需要重新启动一下Tomcat才能生效，否则依然进入不了管理界面

Tomcat 7 下与Tomcat 6 稍有不同，如下所示：
5：修改Tomcat的默认端口
有时候由于特性情况，需要修改Tomcat的默认端口8080，例如端口号被其它应用程序占用了等，这时你需要修改server.xml，在里面
找到如下图所示地方，修改为port的值。注意：修改后需要重启Tomcat服务。

6：修改Tomcat使用的JDK
首先我们先安装JDK1.6，如下所示
1: # chmod +x jdk-6u31-linux-x64-rpm.bin
2: # ./jdk-6u31-linux-x64-rpm.bin

34: Product Registration is FREE and includes many benefits:
35: * Notification of new versions, patches, and updates
36: * Special offers on Oracle products, services and training
37: * Access to early releases and documentation
38: Product and system data will be collected. If your configuration
39: supports a browser, the JDK Product Registration form will
40: be presented. If you do not register, none of this information
41: will be saved. You may also register your JDK later by
42: opening the register.html file (located in the JDK installation
43: directory) in a browser.
44: For more information on what data Registration collects and
45: how it is managed and used, see:
46: http://java.sun.com/javase/registration/JDKRegistrationPrivacy.html
47: Press Enter to continue.....
48:
49: Done.
修改catalina.sh，增加export JAVA_HOME=/usr/java/jdk1.6.0_31即可。如下所示，似乎不用重启，Tomcat使用的JDK就改为了jdk1.6
http://images.cnitblog.com/blog/73542/201403/082331193009494.png
# ./shutdown.sh
Using CATALINA_BASE: /usr/local/tomcat/apache-tomcat-6.0.39
Using CATALINA_HOME: /usr/local/tomcat/apache-tomcat-6.0.39
Using CATALINA_TMPDIR: /usr/local/tomcat/apache-tomcat-6.0.39/temp
Using JRE_HOME: /usr/java/jdk1.6.0_31
Using> # ./startup.sh
Using CATALINA_BASE: /usr/local/tomcat/apache-tomcat-6.0.39
Using CATALINA_HOME: /usr/local/tomcat/apache-tomcat-6.0.39
Using CATALINA_TMPDIR: /usr/local/tomcat/apache-tomcat-6.0.39/temp
Using JRE_HOME: /usr/java/jdk1.6.0_31
Using> #
http://images.cnitblog.com/blog/73542/201403/082331240505177.png
另外，似乎网上也有文章介绍，在文件setclasspath.sh下加入export JAVA_HOME=/usr/java/jdk1.6.0_31 设置即可，那种比较合理，目前不得而知。
7：Tomcat端口被占用分析
有时候明明Tomcat配置OK，Tomcat服务启动正常，但是打开页面的时候出错。这时可能是Tomat端口被占用了，你可以查看一下那些程序占用了Tomcat的端口
# netstat -an | grep 8080
# netstat -apn | grep 8080
一般你也会在catalina.out日志里面找到”SEVERE: Error initializing endpoint java.net.BindException: Permission denied:8080“之类的错误。
1: $ more catalina.out
2: Mar 4, 2014 4:22:14 PM org.apache.catalina.core.AprLifecycleListener init
3: INFO: The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found on the ja
4: va.library.path: /usr/java/jdk1.6.0_31/jre/lib/amd64/server:/usr/java/jdk1.6.0_31/jre/lib/amd64:/usr/java/jdk1.6.0_31/jre/../lib/amd

22: Mar 4, 2014 4:22:15 PM org.apache.catalina.startup.Catalina load
23: SEVERE: Catalina.start
这时要么修改Tomcat的默认端口号，要么修改其它应用程序的端口号。
Tomcat卸载
Tomcat的卸载非常简单，只需要将Tomcat的CATALINA_BASE目录删除，然后删除一些环境变量即可。
# rm -rf /usr/local/tomcat/
