Linux Tomcat 6.0安装配置实践总结

时间:2023-12-15 15:50:26


系统环境:
Red Hat Enterprise Linux Server release 5.7 (Tikanga)  64位

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“Archiveshttp://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: [root@DB-Server tmp]# chmod +x jdk-7u25-linux-x64.rpm  

   2:  

   3: [root@DB-Server tmp]# rpm -ivh jdk-7u25-linux-x64.rpm  

   4: Preparing... ########################################### [100%] 

   5:    1:jdk ########################################### [100%] 

   6: Unpacking JAR files... 

   7:         rt.jar... 

   8:         jsse.jar... 

   9:         charsets.jar... 

  10:         tools.jar... 

  11:         localedata.jar... 

  12: [root@DB-Server tmp]# 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 CLASSPATH=/usr/java/jdk1.7.0_25/lib

export PATH=$JAVA_HOME/bin:$PATH

   1: [root@DB-Server jdk1.7.0_25]# vi /etc/profile

   2: [root@DB-Server jdk1.7.0_25]# source /etc/profile   --生效修改配置信息

   3:  

   4: [root@DB-Server jdk1.7.0_25]# echo $JAVA_HOME

   5: /usr/java/jdk1.7.0_25

   6: [root@DB-Server jdk1.7.0_25]# echo $CLASSPATH

   7: /usr/java/jdk1.7.0_25/lib

   8: [root@DB-Server jdk1.7.0_25]# 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: [root@DB-Server jdk1.7.0_25]# 

Step 2:安装Tomcat

   1: [root@DB-Server tmp]#tar zxvf apach-tomcat-6.0.16.tar.gz

   2:  

   3: [root@DB-Server tmp]#mkdir /usr/local/tomcat

   4:  

   5: [root@DB-Server tmp]# mv apache-tomcat-6.0.39 /usr/local/ tomcat

   6:  

   7:  

   8: [root@DB-Server tomcat]# vi /etc/profile

   9:  

  10: export TOMCAT_HOME=/usr/local/tomcat

  11:  

  12:  

  13: [root@DB-Server tomcat]# source /etc/profile

  14: [root@DB-Server tomcat]# echo $TOMCAT_HOME

  15: /usr/local/tomcat

  16:  

  17:  

  18: [root@DB-Server bin]# pwd

  19: /usr/local/tomcat/apache-tomcat-6.0.39/bin

  20: [root@DB-Server bin]# ./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: [root@DB-Server ~]# groupadd tomcat

   2:  

   3: [root@DB-Server ~]# useradd -g tomcat -d /home/tomcat -u 502 tomcat

   4:  

   5: Creating mailbox file: File exists

   6:  

   7: [root@DB-Server tomcat]# chown -Rf    tomcat.tomcat   /usr/local/tomcat/

   8:  

   9: [root@DB-Server tomcat]#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,

[root@DB-Server apache-tomcat-6.0.39]# ls

bin       lib                logs           RELEASE-NOTES      temp     work

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: [root@DB-Server bin]# ./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: [root@DB-Server bin]# ./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: [root@DB-Server bin]#

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: [root@DB-Server bin]# ./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: [root@DB-Server conf]# 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

[root@DB-Server conf]# cp tomcat-users.xml tomcat-users.xml.20130308.bak

[root@DB-Server conf]# vi tomcat-users.xml

<role rolename="admin" />

<role rolename="manager" />

<user username="admin" password="Qwe!23" roles="admin,manager" />

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

Linux Tomcat 6.0安装配置实践总结

Tomcat 7 下与Tomcat 6 稍有不同,如下所示:

<role rolename="admin-gui"/>

<role rolename="manager-gui"/>

<user username="admin" password="xxxx" roles="admin-gui , manager-gui "/>

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: [root@DB-Server tmp]# chmod +x jdk-6u31-linux-x64-rpm.bin

   2: [root@DB-Server tmp]# ./jdk-6u31-linux-x64-rpm.bin

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

[root@DB-Server bin]# ./shutdown.sh

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

[root@DB-Server bin]# netstat -an | grep 8080

[root@DB-Server bin]# 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<null>:8080“之类的错误。

   1: [root@DB-Server logs]$ more catalina.out  

   2: Mar 4, 2014 4:22:14 PM org.apache.catalina.core.AprLifecycleListener init

  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。

[root@DB-Server ~]# rm -rf /usr/local/tomcat/
