class="hl1">Tomcat</span>，在windows服务上没有启动项，所以需要手动添加，然后可以设置开机启动<span class="hl1">tomcat</span>。</p><p>一、安装服务</p><p>在命令行中进入/<span class="hl1">Tomcat</span>路径/bin/，执行“service.bat install”：（开始-运行,输入cmd,cd<span class="hl1">Tomcat</span>路径/bin,service.bat install）。到此为止windows服务上就增加了一个<span class="hl1">tomcat</span>服务</p><p>?</p><p>说明：</p><p>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<span class="hl1">Tomcat</span>4、<span class="hl1">Tomcat</span>5、<span class="hl1">Tomcat</span>6，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；</p><p>2、防火墙的影响：/bin/<span class="hl1">tomcat</span>6.exe（或<span class="hl1">tomcat</span>4.exe、<span class="hl1">tomcat</span>5.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。</p><p>二、卸载服务</p><p>在命令行中进入/<span class="hl1">Tomcat</span>路径/bin/，执行“service.bat remove”：</p><p><a
