Ubuntu为Tomcat启用80端口
一、tomcat部署调试
?
Update the package repository
sudo apt-get updatesudo 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/80touch /etc/authbind/byport/443chmod 0755 /etc/authbind/byport/80chmod 0755 /etc/authbind/byport/443chown tomcat7:tomcat7 /etc/authbind/byport/80chown 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/tomcat7sudo mkdir logssudo 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。
