一  修改tomcat-user.xml配置檔案
-rw-------. 1 root root   2294 Jan 20 05:37 tomcat-users.xml
-rw-------. 1 root root 168893 Sep 29 05:27 web.xml
[[email protected] conf]# pwd
/usr/local/tomcat/conf

修改tomcat-user.xml

<tomcat-users>
<!--
  NOTE:  By default, no user is included in the "manager-gui" role required
  to operate the "/manager/html" web application.  If you wish to use this app,
  you must define such a user - the username and password are arbitrary. It is
  strongly recommended that you do NOT use one of the users in the commented out
  section below since they are intended for use with the examples web
  application.
-->
<!--
  NOTE:  The sample user and role entries below are intended for use with the
  examples web application. They are wrapped in a comment and thus are ignored
  when reading this file. If you wish to configure these users for use with the
  examples web application, do not forget to remove the <!.. ..> that surrounds
  them. You will also need to set the passwords to something appropriate.
-->
<!--
  <role rolename="tomcat"/>
  <role rolename="role1"/>
  <user username="tomcat" password="<must-be-changed>" roles="tomcat"/>
  <user username="both" password="<must-be-changed>" roles="tomcat,role1"/>
  <user username="role1" password="<must-be-changed>" roles="role1"/>
-->
<role rolename="admin-gui"/>
<role rolename="admin-script"/>
<role rolename="manager-gui"/>
<role rolename="manager-script"/>
<role rolename="manager-jmx"/>
<role rolename="manager-status"/>
<user username="admin" password="admin" roles="manager-gui,manager-script,manager-jmx,manager-status,admin-script,admin-gui"/> 
</tomcat-users>
 

配置tomcat-users 如上圖說是 設定使用者名稱密碼

二 修改maven的setting檔案

        <server>
        <id>releases</id>
        <username>admin</username>
        <password>admin123</password>
        </server>
        

        <server>
        <id>snapshots</id>
        <username>admin</username>
        <password>admin123</password>
        </server>
    </servers>
 

如上所示在servers中新增

<server>
     <id>tomcat7</id>
   <username>admin</username>
   <password>admin</password>
</server>

三修改專案的pom檔案

  <build>
		<!-- 配置外掛 -->
		<plugins>
			 <plugin>
				<groupId>org.apache.tomcat.maven</groupId>
				<artifactId>tomcat7-maven-plugin</artifactId>
				<configuration>
					 <url>http://192.168.232.129:8080/manager/text</url> 
                	   <server>tomcat7</server>
                	   <username>admin</username>  
            		   <password>admin</password>  
				</configuration>
			</plugin> 
		</plugins>
	</build>
 

run as

"tomcat7:deploy"

這裡一定要注意，原tomcat是有Root路徑的，如果有ROOT要用

"tomcat7:redploy"的方式進行部署，不然就不生效

就可以進行熱部署了。
