The first method: need to configure environment variables
first tomcat
Configure the CATALINA_HOME environment variable to point to the tomcat installation directory
For example: E:\sdfxw\tomcat5-sdfxw
Configure the environment variable path to point to %CATALINA_HOME%\bin
Enter /Tomcat path/bin/ in the command line, execute "service.bat install [service name] So far, a tomcat service has been added to the windows service.
Install second tomcat
Configure the CATALINA_HOME2 environment variable to point to another tomcat directory
Configure the environment variable path to point to %CATALINA_HOME2@%\bin
Enter the bin directory of tomcat and find catalina.bat, startup.bat, service.bat
Replace all CATALINA_HOME with CATALINA_HOME2
Enter the second /Tomcat path/bin/ in the command line, and execute "service.bat install": (start-run, enter cmd, cd Tomcat path/bin, service.bat install). So far, a tomcat service has been added to the windows service
So far, the two tomcat configurations are complete
Of course, you need to modify the port of tomcat, which will not be said here.
The second method
Applicable to Tomcat4.1, 5.5, 6.0.
For the decompressed version of Tomcat installation, see: http://www.blogjava.net/fastunit/archive/2008/05/22/202112.html
Because the decompressed version of Tomcat does not have a startup item on the windows service, it needs to be added manually, and then you can set the startup to start tomcat.
1. Installation service
Enter /Tomcat path/bin/ on the command line, and execute "service.bat install": (Start-Run, enter cmd, cd Tomcat path/bin, service.bat install). So far, a tomcat service has been added to the windows service
illustrate:
1、服务名和显示名称：service.bat中设置了默认的服务名称，不同版本分别命名为Tomcat4、Tomcat5、Tomcat6，如果需要自定义服务名或服务的显示名称，可在service.bat中修改SERVICE_NAME或PR_DISPLAYNAME；
2、防火墙的影响：/bin/tomcat6.exe（或tomcat4.exe、tomcat5.exe）将被作为服务程序，如果有防火墙，需要设为允许作为服务。
二、卸载服务
在命令行中进入/Tomcat路径/bin/，执行“service.bat remove”：
三、命令行参数
Tomcat的服务名、Jvm内存初始值和最大值等可通过命令行参数设置，请参考官方文档：
http://tomcat.apache.org/tomcat-5.5-doc/windows-service-howto.html
http://tomcat.apache.org/tomcat-6.0-doc/windows-service-howto.html
四、开机启动Tomcat设置
开始-控制面板-管理工具-服务
找到apche tomcat 右键属性，把手动改为自动
如果还是不行，也可以添加任务。操作步骤
开始==》控制面板==》任务计划==》添加任务计划
下一步
浏览
找到免安装的tomcat根目录下的bin目录，选择startup.bat打开
选择计算机启动时
下一步
输入用户名和密码
完成
安装第二个Tomcat重复一次上面操作即可
这个我没有经过测试，个人认为应该可用
