Tomcat安裝及查看相關信息

用到的安裝包：               
      jdk-7u5-linux-i586.rpm    
      apache-tomcat-7.0.29.tar.gz               

系統環境：
       CentOS 5.8

一、 安裝Tomcat（需要先安裝JDK）

1. 安裝JDK
     # rpm -ivh jdk-7u5-linux-i586.rpm
        
2. 定義兩個環境變量      
      # vi /etc/profile                    
          JAVA_HOME=/usr/java/jdk1.7.0_05
          PATH=$PATH:$JAVA_HOME/bin
          export JAVA_HOME PATH USER LOGNAME MAIL HOSTNAME HISTSIZE INPUTRC                   
               
3. 退出後再重新登錄
      # printenv                    查看環境變量

          .....
          PATH=/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/java/jdk1.7.0_05/bin:/root/bin
          JAVA_HOME=/usr/java/jdk1.7.0_05
                    .....
               
       # java -version   

4. 安裝 Tomcat
       # tar xf apache-tomcat-7.0.29.tar.gz -C /usr/local/
       # cd /usr/local/
       # ln -sv apache-tomcat-7.0.29/  tomcat
              create symbolic link `tomcat' to `apache-tomcat-7.0.29/'

二、 查看Tomcat的版本信息

[root@node2 tomcat]# bin/catalina.sh version
Using CATALINA_BASE:   /usr/local/tomcat
Using CATALINA_HOME:   /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME:        /usr/java/jdk1.7.0_05
Using CLASSPATH:       /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
Server version: Apache Tomcat/7.0.29
Server built:   Jul 3 2012 11:31:52
Server number:  7.0.29.0
OS Name:        Linux
OS Version:     2.6.18-308.el5
Architecture:   i386
JVM Version:    1.7.0_05-b05
JVM Vendor:     Oracle Corporation

[root@node2 tomcat]# bin/catalina.sh        catalina.sh 可以調用其它的腳本，
Using CATALINA_BASE:   /usr/local/tomcat
Using CATALINA_HOME:   /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME:        /usr/java/jdk1.7.0_05
Using CLASSPATH:       /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
Usage: catalina.sh ( commands ... )       支持很多的選項，常用的如下：
commands:
  debug             Start Catalina in a debugger
  debug -security   Debug Catalina with a security manager
  jpda start        Start Catalina under JPDA debugger
  run               Start Catalina in the current window
  run -security     Start in the current window with security manager
  start             Start Catalina in a separate window
  start -security   Start in a separate window with security manager
  stop              Stop Catalina, waiting up to 5 seconds for the process to end
  stop n            Stop Catalina, waiting up to n seconds for the process to end
  stop -force       Stop Catalina, wait up to 5 seconds and then use kill -KILL if still running
  stop n -force     Stop Catalina, wait up to n seconds and then use kill -KILL if still running
  configtest        Run a basic syntax check on server.xml - check exit code for result
  version           What version of tomcat are you running?
Note: Waiting for the process to end and use of the -force option require that $CATALINA_PID is defined

三、啓動Tomcat

[root@node2 tomcat]# bin/catalina.sh start
Using CATALINA_BASE:   /usr/local/tomcat
Using CATALINA_HOME:   /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME:        /usr/java/jdk1.7.0_05
Using CLASSPATH:       /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar

查看啓動的進程

[root@node2 tomcat]# netstat -tnlp

四、訪問Tomcat （Tomcat 默認的虛擬主機是監聽在8080端口的）
