Ubuntu为Tomcat启用80端口

Ubuntu为Tomcat启用80端口

一、tomcat部署调试

 

Update the package repository

sudo apt-get update
sudo apt-get upgrade --show-upgrades 

 
Install the authbind package

 

 

sudo apt-get install authbind

 
This package allows non-root users to bind to ports below 1024. Install the tomcat7 package

sudo apt-get install tomcat7

 

The tomcat7-docs, tomcat7-examples,and tomcat7-admin packages aren't required to deploy and maintain a web application. These packages can be skipped unless they are truly needed.

A new user "tomcat7" with primary group "tomcat7" will be created.



Enable authbind
Open a text editor like vim and load the default tomcat configuration file

nano /etc/default/tomcat7

 

Remove the comment hash "#" in front of the authbind property and set the value to "yes"

AUTHBIND=yes

 

Create authbind bind permission files for ports 80 and 443. Authbind will loop through the directory structure and try to find a byPort file referencing the port number attempting to be bound. Authorization will be granted if the user attempting to bind has execute permission.

touch /etc/authbind/byport/80
touch /etc/authbind/byport/443
chmod 0755 /etc/authbind/byport/80
chmod 0755 /etc/authbind/byport/443
chown tomcat7:tomcat7 /etc/authbind/byport/80
chown tomcat7:tomcat7 /etc/authbind/byport/443

 

Change the Tomcat Port from 8080/8443 to 80/443
Open a text editor like vim and load the server configuration file

nano /etc/tomcat7/server.xml

 

Find the connector for port 8080 to port 80 and the redirect port from 8443 to 443:

<Connector port="80" protocol="HTTP/1.1" 
connectiontimeout="20000" uriencoding="UTF-8" 
redirectport="443">
</Connector>

 
Restart the Tomcat service

sudo service tomcat7 restart

 
View the catalina.out log after restart and look for any errors. If you see permission denied errors, then you may have missed a step like: 
Forgetting to uncomment the AuthBind setting and putting it to "yes"
Forgetting to restart the tomcat7 service as sudo

 

最后运行netstat -ant，查看80端口是否起来 。

 

二、应用部署

 

tomcat配置成功后需要将开发的应用部署到tomcat服务器中。步骤如下：

1、将应用打包为ROOT.war

2、在/usr/share/tomcat7中创建logs目录

 

cd /usr/share/tomcat7
sudo mkdir logs
sudo chmod 755 logs

3、创建ROOT.xml文件内容如下：

 

<!-- The contents of this file will be loaded for each web application -->


<Context path="" docBase="/usr/share/tomcat7/ROOT.war" displayName="Tomcat_1" reload="false" 
        debug="0" privileged="true">

    <!-- Default set of monitored resources -->

    <WatchedResource>WEB-INF/web.xml</WatchedResource>

</Context>

   其中 docBase="/usr/share/tomcat7/ROOT.war"指向应用部署所在文件地址。

 

4、 重启tomcat

 

sudo service tomcat7 restart

 提示信息如下：

 

 * Stopping Tomcat servlet engine tomcat7
   ...done.
 * Starting Tomcat servlet engine tomcat7
   ...done.

 启动完毕后登陆应用地址查看。如还不成功请参考上述步骤修改。
