一台机器多个应用实例配置

来源：互联网发布：一次性筷子味道知乎编辑：程序博客网时间：2024/05/22 06:21

例如有三个应用 a.com,b.com,c.com

一：安装tomcat

tomcat安装目录：/export/servers/tomcat6.0.33/

目录列表如下图：

二：多应用实例服务配置(列举 a.com,其他应用实例b和c 和 a实例配置只有红色标识不一样)

（1）实例路径目录如下是（这些文件是从tomcat安装目录下复制过来）：

/export/Domains/a.com/server1/

/bin/

/start.sh

/stop.sh

/conf/

/Catalina/

/localhost/

/ROOT.xml

/catalina.policy

/catalina.properties

/context.xml

/logging.properties

/server.xml.bak

/server.xml

/tomcat-users.xml

/web.xml

/logs/

/catalina.out

/catalina.out.autodeploy

/host-manager.log

/localhost.log

/manager.log

/temp/

/work/

/catalina.pid

（2）

start.sh文件配置修改后的内容：

#!/bin/bash

#chown 555 -R /export/home/tomcat/domains/
export CATALINA_HOME=/export/servers/tomcat6.0.33
export CATALINA_BASE=/export/Domains/a.com/server1
