Maven remote deploy

11/07/2013 Baiazid

Remote deploy to a Tomcat Server using Maven 3

1. Install maven tomcat7 plugin (you need manager application in tomcat7 – comes by default)

<plugin>
    <groupId>org.apache.tomcat.maven</groupId>
    <artifactId>tomcat7-maven-plugin</artifactId>
    <version>2.1</version>
    <configuration>
        <url>http://10.0.0.11:8080/manager/text</url>
        <server>tomcat</server>
        <path>/MyApp</path>
    </configuration>
</plugin>

<groupId>org.apache.tomcat.maven</groupId>

<artifactId>tomcat7-maven-plugin</artifactId>

<url>http://10.0.0.11:8080/manager/text</url>

<server>tomcat</server>

<path>/MyApp</path>

</configuration>

</plugin>

2. Configure maven settings.xml in ~/.m2/ (or the place where maven is reading settings.xml)

<server>
    <id>tomcat</id>
     <username>my_user</username>
     <password>my_password</password>
</server>

<id>tomcat</id>

<password>my_password</password>

</server>

3. Configure tomcat users in /usr/share/apache-tomcat-7.0.39/conf/tomcat-users.xml

<tomcat-users>
    <role rolename="manager-gui"/>
    <role rolename="manager-script"/>
    <role rolename="manager-jmx"/>
    <role rolename="manager-status"/>
    <role rolename="admin-gui"/>
    <role rolename="admin-script"/>
    <user username="my_user" password="my_password" roles="manager-gui,manager-script,manager-jmx,
           manager-status,admin-gui,admin-script"/>
</tomcat-users>

<tomcat-users>

<user username="my_user" password="my_password" roles="manager-gui,manager-script,manager-jmx,

manager-status,admin-gui,admin-script"/>

</tomcat-users>

4. Execute Maven goals

org.apache.tomcat.maven:tomcat7-maven-plugin:2.1:undeploy
clean
org.apache.tomcat.maven:tomcat7-maven-plugin:2.1:deploy

org.apache.tomcat.maven:tomcat7-maven-plugin:2.1:undeploy

clean

org.apache.tomcat.maven:tomcat7-maven-plugin:2.1:deploy

5. Tips and Tricks

It is preferable to have a maven profile for each server (DEV, TEST, PROD), in case you have database connections and servers are different. In this way, your war file will be build with predefined IP addresses and parameters for each particular deploy.

Apache Tomcat, Nginx

Reverse Proxy Nginx -> Tomcat

14/05/2013 Baiazid

We need two servers:

NGINX
- Serve static files
- Serve maintenance page
- Control access via GeoIP tables
- Offer HTTPS protocol to clients (443)
- Maintain reverse proxy to Tomcat on HTTP
TOMCAT
- Will hold deployed application
- Communicates on port 8080

For a reverse proxy we need to configure nginx:

nginx.conf

...
http {
    ...    
    # Tomcat
    upstream tomcat {
       server localhost:8080;
    }

    ...
    include /etc/nginx/conf.d/*.conf;

...

http {

...

# Tomcat

upstream tomcat {

server localhost:8080;

}

...

include /etc/nginx/conf.d/*.conf;

site.conf

server {
    ...
    location / {
        proxy_set_header Host $http_host;
        proxy_set_header X-Forwarded-Host $host;
        proxy_set_header X-Forwarded-Server $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-Proto https;
        proxy_set_header Authorization "";
        proxy_redirect off;
        proxy_connect_timeout 240;
        proxy_send_timeout 240;
        proxy_read_timeout 240;
        proxy_pass http://tomcat;
    }
    ...
}

server {

...

location / {

proxy_set_header Host $http_host;

proxy_set_header X-Forwarded-Host $host;

proxy_set_header X-Forwarded-Server $host;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

proxy_set_header X-Real-IP $remote_addr;

proxy_set_header X-Forwarded-Proto https;

proxy_set_header Authorization "";

proxy_redirect off;

proxy_connect_timeout 240;

proxy_send_timeout 240;

proxy_read_timeout 240;

proxy_pass http://tomcat;

}

...

}

Tomcat configuration more simple:

server.xml

...
    &lt;Connector port="8080" protocol="HTTP/1.1"
        connectionTimeout="20000"
        redirectPort="8443"
        proxyPort="443"
    /&gt;
...

...

<Connector port="8080" protocol="HTTP/1.1"

connectionTimeout="20000"

redirectPort="8443"

proxyPort="443"

...

Install Tomcat on MacOSX

09/12/2012 Baiazid

Download latest version of Tomcat (tar.gz) from http://tomcat.apache.org/

In my case I am using apache-tomcat-7.0.33.tar.gz

Extract the archive:

tar -xf ~/Downloads/apache-tomcat-7.0.33.tar.gz

1	tar -xf ~/Downloads/apache-tomcat-7.0.33.tar.gz

Move the extracted directory to /usr/local:

sudo mv ~/Downloads/apache-tomcat-7.0.33 /usr/local

1	sudo mv ~/Downloads/apache-tomcat-7.0.33 /usr/local

Remove old Tomcat (if available)

sudo rm -f /Library/Tomcat

1	sudo rm -f /Library/Tomcat

Create a symlink to Library directory:

sudo ln -s /usr/local/apache-tomcat-7.0.33 /Library/Tomcat

1	sudo ln -s /usr/local/apache-tomcat-7.0.33 /Library/Tomcat

If you want to access manager, edit /conf/tomcat-users.xml and add:

  &lt;role rolename="manager"/&gt;
  &lt;role rolename="manager-gui"/&gt;
  &lt;role rolename="admin-gui"/&gt;
  &lt;user username="myname" password="secret" roles="manager,manager-gui,admin-gui"/&gt;

Then you can login with “myname” and “secret”
