$   scp dubbo-admin-2.5.4-SNAPSHOT.war hbb@192.168.2.108:/home/hbb/tool/dubbo-admin/

失败的尝试

主要失败点: 和已有的 jenkins 有冲突。如果没有其他war,这个就够了。

  • copy to tomcat
  [plaintext]

$   cp dubbo-admin-2.5.4-SNAPSHOT.war ~/tool/tomcat/tomcat9/webapps/

$ pwd
/home/hbb/tool/tomcat/tomcat9/webapps
  • config server.xml

靠最后添加这一行:

  [plaintext]

<!-- Tomcat Manager Context -->
    <Context path="/dubbo-admin" docBase="dubbo-admin-2.5.4-SNAPSHOT" debug="0" privileged="true" reloadable="true"/>

整体这样子:

<Server>

    <!-- Tomcat Manager Context -->
    <Context path="/dubbo-admin" docBase="dubbo-admin-2.5.4-SNAPSHOT" debug="0" privileged="true" reloadable="true"/>
</Service>
</Server>

因为有jenkins为ROOT.war的原因,会导致访问不到dubbo。

为方便jenkins的访问使用,将dubbo-admin放在另外一个tomcat下面。

暂时设定port为8079

创建dubbo专属的tomcat

准备工作

解压一份

  [plaintext]
1
tar -zxf apache-tomcat-9.0.0.M15.tar.gz

重命名:

3
$   mv apache-tomcat-9.0.0.M15 tomcat9_dubbo
$   ls
apache-tomcat-9.0.0.M15.tar.gz  tomcat9  tomcat9_dubbo

复制 dubbo-admin.war 到新的tomcat下面:

建议: 如果tomat默认额包不用,可以删除。删除方式如下:

  [plaintext]
1
$   rm -rf ${TOMCAT_HOME}/webapps/*
  [plaintext]
1
$   cp ~/tool/tomcat/tomcat9/webapps/dubbo-admin-2.5.4-SNAPSHOT.war ~/tool/tomcat/tomcat9_dubbo/webapps/

重命名:

  [plaintext]

$ mv dubbo-admin-2.5.4-SNAPSHOT.war ROOT.war

配置修改

(1) 修改tomcat端口并指定编码

<!-- A "Connector" represents an endpoint by which requests are received
         and responses are returned. Documentation at :

               connectionTimeout="20000"
               redirectPort="8443" URIEncoding="UTF-8" />

(2) 端口占用问题

如果此时8080的tomcat是启动的,你应该会遇到如下端口占用错误。我们明明修改了端口啊?可是tomcat占用的不仅仅是一个8080.

下面这段log在 ${TOMCAT_HOME}/logs/catalina.out.log

重启tomcat,不出意外应该有喜闻乐见的端口占用。。。(修改需谨慎,确保无冲突)

应该是成功了。登陆看看吧。。。

dubbo.registry.address=zookeeper://127.0.0.1:2181

当然也可以自定修改,修改后需要重启tomcat方能生效。
