1.在tomcat容器中部署多个service 在server.conf中配置 [html] view plain copy <?xml version='1.0' encoding='utf-8'?>

<Resource name="UserDatabase" auth="Container"  
          type="org.apache.catalina.UserDatabase"  
          description="User database that can be updated and saved"  
          factory="org.apache.catalina.users.MemoryUserDatabaseFactory"  
          pathname="conf/tomcat-users.xml" />  

<Resource name="discoveryServiceDatabase" auth="Container"  
          type="org.apache.catalina.UserDatabase"  
          description="User database that can be updated and saved"  
          factory="org.apache.catalina.users.MemoryUserDatabaseFactory"  
          pathname="conf/tomcat-users.xml" />  


<Resource name="configurationServiceDatabase" auth="Container"  
          type="org.apache.catalina.UserDatabase"  
          description="User database that can be updated and saved"  
          factory="org.apache.catalina.users.MemoryUserDatabaseFactory"  
          pathname="conf/tomcat-users.xml" />  

<Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000"  redirectPort="8443" />  
<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />  
<Engine name="Catalina" defaultHost="localhost">  
  <Realm className="org.apache.catalina.realm.LockOutRealm">  
    <Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="UserDatabase"/>  
  </Realm>  
    <Host name="localhost"  appBase="webapps"   unpackWARs="true" autoDeploy="true">  
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" prefix="localhost_access_log" suffix=".txt" pattern="%h %l %u %t "%r" %s %b" />  
  </Host>  
</Engine>  

<Connector port="8761" protocol="HTTP/1.1" connectionTimeout="20000"  redirectPort="8444" />  
<Connector port="8010" protocol="AJP/1.3" redirectPort="8444" />  
<Engine name="discoveryService" defaultHost="discoveryHost">  
  <Realm className="org.apache.catalina.realm.LockOutRealm">  
    <Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="discoveryServiceDatabase"/>  
  </Realm>  
    <Host name="discoveryHost"  appBase="discoveryapp"   unpackWARs="true" autoDeploy="true">  
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" prefix="discovery_access_log" suffix=".txt" pattern="%h %l %u %t "%r" %s %b" />  
  </Host>  
</Engine>  

<Connector port="1221" protocol="HTTP/1.1" connectionTimeout="20000"  redirectPort="8445" />  
<Connector port="8011" protocol="AJP/1.3" redirectPort="8445" />  
<Engine name="configurationService" defaultHost="configurationHost">  
  <Realm className="org.apache.catalina.realm.LockOutRealm">  
    <Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="configurationServiceDatabase"/>  
  </Realm>  
    <Host name="configurationHost"  appBase="configurationapp"   unpackWARs="true" autoDeploy="true">  
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" prefix="configuration_access_log" suffix=".txt" pattern="%h %l %u %t "%r" %s %b" />  
  </Host>  
</Engine>  

上面这样子配置完之后 tomcat启动 可以用以下url访问对应的service

localhost:8761/ localhost:8080/ localhost:1221/

注意点： 1 service标签name不能重复 2.connector中的端口号不能重复 3.realm中的resourceName 对应上面的resource标签 4.host中的appBase的目录从tomcat安装目录开始 {TOMCAT_HOME}/{对应的目录名字} 5.重点：上述的配置war包名字必须是ROOT，而且没有虚拟路径。虚拟路径需要在host标签新增下面属性： docBase 是war包的路径，path是虚拟路径，虚拟路径的名称必须和war包名称一致

1. 利用manager重启单个service 2.1把tomcat自带的manager工程放到对应的目录中

2.2tomcat中添加用户权限 tomcat-users.xml [html] view plain copy <tomcat-users xmlns="http://tomcat.apache.org/xml"

          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
          xsi:schemaLocation="http://tomcat.apache.org/xml tomcat-users.xsd"  
          version="1.0">  

重启tomcat后 访问页面 http://172.19.103.33:8761/manager/html

就可以通过上面的按钮去重启service 注意点: 1.改种方式 要考虑安全性 建议部署tomcat在内网

1. 安装完manager后利用rest重启单个service 资料：http://tomcat.apache.org/tomcat-8.0-doc/manager-howto.html#Reload_An_Existing_Application

重启的rest接口

HEADER中要放入Basic验证信息 Authorization Basic Y3dkOmN3ZA== (在tomcat-users.xml配置的账号密码的加密 格式 cwd:cwd )

GET http://172.19.103.33:8761//manager/text/reload?path=/ path代表项目的目录 /默认是 ROOT目录

请求成功后返回message OK - Reloaded application at context path

例如

返回请求
