前景提要：

为了实现服务器使用效率最大化，有必要配置两个tomcat在一个或多个服务器中。下面介绍在同一个服务器配置两个Tomcat的过程。

详细步骤讲解：

1、拷贝原来的Tomcat到另外一个目录，并且重新命名 如：tomcat1

![Center][]

2、修改Tomcat1中的server.xml文件，把shutdown和Connector端口修改成另外的数值，如8006/8081

以下是我修改后的相关文件：

<?xml version='1.0' encoding='utf-8'?>
    
    
    <Server port="8006" shutdown="SHUTDOWN">
      
      
      <Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" />
      
      <Listener className="org.apache.catalina.core.JasperListener" />
      
      <Listener className="org.apache.catalina.core.JreMemoryLeakPreventionListener" />
      <Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" />
      <Listener className="org.apache.catalina.core.ThreadLocalLeakPreventionListener" />
    
      
      <GlobalNamingResources>
        
        <Resource name="UserDatabase" auth="Container"
                  type="org.apache.catalina.UserDatabase"
                  description="User database that can be updated and saved"
                  factory="org.apache.catalina.users.MemoryUserDatabaseFactory"
                  pathname="conf/tomcat-users.xml" />
      </GlobalNamingResources>
    
      
      <Service name="Catalina">
    
        
        
    
    
        
        <Connector port="8081" protocol="HTTP/1.1"
                   connectionTimeout="20000"
                   redirectPort="8443" />
        
        
        
        
    
        
        <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />
    
    
        
    
        
        <Engine name="Catalina" defaultHost="localhost">
    
          
          
    
          
          <Realm className="org.apache.catalina.realm.LockOutRealm">
            
            <Realm className="org.apache.catalina.realm.UserDatabaseRealm"
                   resourceName="UserDatabase"/>
          </Realm>
    
          <Host name="localhost"  appBase="webapps"
                unpackWARs="true" autoDeploy="true">
    
            
            
    
            
            <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
                   prefix="localhost_access_log." suffix=".txt"
                   pattern="%h %l %u %t "%r" %s %b" />
    
          </Host>
        </Engine>
      </Service>
    </Server>

3、修改startup.sh和shutdown.sh文件，在第一行加入：  
export CATALINA\_HOME=/usr/local/tomcat1

以下是相关配置文件：

shutdown.sh

    esac
    
    # resolve links - $0 may be a softlink
    PRG="$0"
    
    while [ -h "$PRG" ] ; do

      link=`expr "$ls" : '.*-> $.*$$'`
      if expr "$link" : '/.*' > /dev/null; then

      else
        PRG=`dirname "$PRG"`/"$link"
      fi
    done
    
    PRGDIR=`dirname "$PRG"`
    EXECUTABLE=catalina.sh
    
    # Check that target executable exists
    if $os400; then
      # -x will Only work on the os400 if the files are:
      # 1. owned by the user
      # 2. owned by the PRIMARY group of the user
      # this will not work if the user belongs in secondary groups
      eval
    else
      if [ ! -x "$PRGDIR"/"$EXECUTABLE" ]; then
        echo "Cannot find $PRGDIR/$EXECUTABLE"
        echo "The file is absent or does not have execute permission"
        echo "This file is needed to run this program"
        exit 1
      fi
    fi
    
    exec "$PRGDIR"/"$EXECUTABLE" stop "$@"
