Tomcat多实例运行配置

23rwd

1、环境变量设置
设置tomcat环境变量如下
export JAVA_HOME=/usr/java/jdk1.7.0_80
export JRE_HOME=$JAVA_HOME/jre
export CLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib:$CLASSPATH
export PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH;
export CATALINA_HOME=/usr/tomcat7
仅设置CATALINA_HOME变量，CATALINA_BASE变量启动时进行指定。

2、实例目录配置
    多实例配置目录如下目录树结构。lib与bin目录位于CATALINA_HOME目录，在CATALINA_HOME目录下创建jason1、jason2实例目录。并拷贝conf logs temp webapps work至各实例目录中。
[iyunv@jason1 tomcat7]# pwd
/usr/tomcat7
[iyunv@jason1 tomcat7]# tree -d -L 2
.
|-- bin
|-- jason1
|   |-- conf
|   |-- logs
|   |-- temp
|   |-- webapps
|   `-- work
|-- jason2
|   |-- conf
|   |-- logs
|   |-- temp
|   |-- webapps
|   `-- work
`-- lib
14 directories
[iyunv@jason1 tomcat7]#

3、配置实例server.xml文件
jason1实例
<?xml version='1.0' encoding='utf-8'?>
<Server port="8005" shutdown="SHUTDOWN">
  <Listener className="org.apache.catalina.startup.VersionLoggerListener" />

      </Realm>
      <Host name="www.jason2.com"  appBase="/usr/tomcat7/jason2/webapps"
            unpackWARs="true" autoDeploy="true">
        <Context path="" docBase="/usr/tomcat7/jason2/webapps/jason2"  reloadable="true" />
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
               prefix="localhost_access_log." suffix=".txt"
               pattern="%h %l %u %t &quot;%r&quot; %s %b" />
      </Host>
    </Engine>
  </Service>
</Server>

jason2实例

  </Service>
</Server>
备注：确保端口号不冲突。

4、启动tomcat实例
启动实例jason1
[iyunv@jason1 temp]# export CATALINA_BASE=/usr/tomcat7/jason1
[iyunv@jason1 temp]# export CATALINA_TMPDIR=/usr/tomcat7/jason1/temp
[iyunv@jason1 temp]# $CATALINA_HOME/bin/startup.sh
Using CATALINA_BASE:   /usr/tomcat7/jason1
Using CATALINA_HOME:   /usr/tomcat7
Using CATALINA_TMPDIR: /usr/tomcat7/jason1/temp
Using JRE_HOME:        /usr/java/jdk1.7.0_80/jre
Using CLASSPATH:       /usr/tomcat7/bin/bootstrap.jar:/usr/tomcat7/bin/tomcat-juli.jar
Tomcat started.
[iyunv@jason1 temp]#
启动实例jason2
[iyunv@jason1 temp]# export CATALINA_BASE=/usr/tomcat7/jason2
[iyunv@jason1 temp]# export CATALINA_TMPDIR=/usr/tomcat7/jason2/temp
[iyunv@jason1 temp]# $CATALINA_HOME/bin/startup.sh
Using CATALINA_BASE:   /usr/tomcat7/jason2
Using CATALINA_HOME:   /usr/tomcat7
Using CATALINA_TMPDIR: /usr/tomcat7/jason2/temp
Using JRE_HOME:        /usr/java/jdk1.7.0_80/jre
Using CLASSPATH:       /usr/tomcat7/bin/bootstrap.jar:/usr/tomcat7/bin/tomcat-juli.jar
Tomcat started.
[iyunv@jason1 temp]#

5、访问测试
已经设置好DNS记录与测试页内容，如下为测试结果
jason1实例测试页显示如下

jason2实例测试页显示如下
