I have installed Tomcat using EasyApache 4, enabled tomcat on the subdomain and it appears the next step is to install the servlets. When I attempt to run the following command, I receive a directory not found error and the script does not appear to be in the scripts directory.

Command:
/scripts/addservlets --domain=subdomain.example.com

Any help installing Tomcat on Centos 6 VPS would be greatly appreciated.

So confirming, there is no additional install servel step with EA4?

That's correct. Once you've installed Tomcat, simply enable Tomcat for the user with the instructions at:

Add Tomcat support for a user

Second, any reason why I would get a ubic command not found error?

We can attempt to reproduce the issue on a test server. Can you let us know the full step-by-step instructions of how you are reproducing the error?

Thank you.

Hello All !

I have enabled the tomcat for the domain and followed the url given by cPanel [ https://documentation.cpanel.net/display/EA4/Tomcat[URL="https://documentation.cpanel.net/display/EA4/Tomcat"]Tomcat - EasyApache 4 - cPanel Documentation [/URL]], i was getting lot of issue but finally i have found the way to get my tomcat application deployed and it it was working well. [Now testing domain remove from server]

Here what i have used to get address my issue, mean everything that you need to do if you want to deploy the tomcat application in easy way, all you need to put your jsp or extracted war under your public_html folder and application will start working.


Enable the Tomcat from cPanel server or from command line then follow the steeps below.

My_Domain : "example.tk" & MY_Username: "example" check your and replace in your case

1) Build your web app [ demo_app.war ] file for example purposes. Rename it to [ demo_app.zip ] and upload over the server by login to cPanel.
2) Upload in your server go to the /home/user-name/ea-tomcat85/webapps/ROOT/ or under your public_html folder location and unzip the file [ demo_app.zip ]
4) Go to /home/demotomcat/ea-tomcat85/conf/ directory, There you should find a server.xml file.
5) Use the command cat/vi/nano server.xml to view the server.xml file. Find the Ajp/1.3 connector port. It should look something like this:

#====================================#====================================
<Connector port="10003" protocol="AJP/1.3" redirectPort="10002"/>
#====================================#====================================

Remember the port number is 10003.

6) Now go to this location: /etc/apache2/conf.d/userdata/std/2_4/user-name/your-domain-name/ [if you are not able to see the folder file then crate it by using below command]


#====================================#====================================
mkdir -p /etc/apache2/conf.d/userdata/std/2_4/demotomcat/demotomcat.tk/
touch /etc/apache2/conf.d/userdata/std/2_4/demotomcat/demotomcat.tk/demotomcat.conf
vi /etc/apache2/conf.d/userdata/std/2_4/demotomcat/demotomcat.tk/demotomcat.conf
#====================================#====================================

Append the below code under file demotomcat.conf

#====================================#====================================
<IfModule proxy_ajp_module>
ProxyPass "/" "ajp://127.0.0.1:10003/"
</IfModule>
#====================================#====================================
Now save it.

8) Now you need to rebuild the HTTPD, so use the below command
#====================================#====================================
/usr/local/cpanel/scripts/rebuildhttpdconf
#====================================#====================================


And now restart the HTTPD by using the below command:

#====================================#====================================
/usr/local/cpanel/scripts/restartsrv_httpd
#====================================#====================================

9) Go to /home/demotomcat/ea-tomcat85/conf/ directory again and append below line in yuor server.xmpl and please append this under the parameter <Host></Host>.

Informative: this is the path where you can modify the same as per your convenience for uploading the jsp application, if you want to upload application under public_html then change it from [ /home/demotomcat/ea-tomcat85/webapps/ROOT/ ] to [ /home/demotomcat/public_html ]

#====================================#====================================
<Context path="/" docBase="/home/demotomcat/ea-tomcat85/webapps/ROOT/"></Context>
#====================================#====================================

10) Finally restart the tomcat server using command [/scripts/ea-tomcat85 all restart ]

#====================================#====================================
/scripts/ea-tomcat85 all restart
#====================================#====================================

Request: I request cPanel Development team to build some script [like manual entry mentioned above] in new cPanel that run after enable the tomcat for domain, so that we don't have to do such task.


Note: If you need SSL configuration for your domain, then i have also tested the same and created my manual steps.

Hello @mikerich6,

Did you make certain to enable SSL in the Tomcat configuration? You can find instructions on the following page for enabling SSL in Tomcat:

Tomcat Private Instances - EasyApache 4 - cPanel Documentation

documentation.cpanel.net documentation.cpanel.net

If you have any difficulty please feel free to submit a ticket using the link in my signature. We will be happy to assist you.

Best regards

Thank you cPSamuel. But correct me if I'm wrong, isn't this Tomcat configuration like a manual SSL thing?
I was expecting a similar behavior that EasyApache 3 had with Tomcat 7 in terms of the SSL certificates, something automatic where the SSL certs autorenew every 3 months (or whatever the timeframe is) and are applied to the whole thing. I'm not very knowledgeable in SSL nor Apache but EA3 (Apache to Tomcat) was pretty good with that.

Does EA4 have that? I'll submit a ticket if that is better.

Thank you!

Hello @mikerich6,

Configuring SSL support for Tomcat must be done manually. cPanel/WHM still includes the AutoSSL tool which allows you to automatically install new SSL certificates periodically. AutoSSL is independent of EasyApache and Tomcat. I do encourage you to go ahead and submit a ticket for further assistance with SSL support for Tomcat, as this is diverging from the original topic of this thread. We will be happy to help with any remaining issues you might have via ticket!

Please enjoy!

Here are the steps. [I recommend having the premium SSL of 1 Year or 3 Year instead of Free so that you will not have to do same thing in each 3 month ]


>>
WHM/TomcatSSL

Note: Mydomain : [ example.tk ] & Myusename: [ example ] check your and replace in your case

I hope you have confiured the tomcat on website [ example.tk ] and now need to enable SSL.

1) Run below commands to created file and folders.
#====================================#====================================
mkdir -p /etc/apache2/conf.d/userdata/ssl/2_4/example/example.tk

touch /etc/apache2/conf.d/userdata/ssl/2_4/example/example.tk/example.conf

nano /etc/apache2/conf.d/userdata/ssl/2_4/example/example.tk/example.conf
#====================================#====================================

2) Use the command [ cat /home/example/ea-tomcat85/conf/server.xml | grep AJP ] to grep the server.xml file. Find the Ajp/1.3 [Connector port="10003"], It should look something like this: [ <Connector port="10003" protocol="AJP/1.3" xpoweredBy="false"/> ]


Write/Append the below code: [Your port number is 10003.]

#====================================#====================================
<IfModule proxy_ajp_module>
ProxyPass "/" "ajp://127.0.0.1:10003/"
</IfModule>
#====================================#====================================

Finally, save it.


3) Now you need to rebuild the HTTPD, so use the below command, And also restart the HTTPD by using the below commands.
#====================================#====================================
/usr/local/cpanel/scripts/rebuildhttpdconf

/usr/local/cpanel/scripts/restartsrv_httpd
#====================================#====================================


4) Prepair the SSL Certification and Key file in p12 file, now upload the crt and key over server any localtion in my case [/home/example/ea-tomcat85/tomcat_ssl/] and run below command to get .p12 keystore file and use password as 123456789

#====================================#====================================
openssl pkcs12 -export -in example.crt -inkey example.key -out mycert.p12 -name tomcat
#====================================#====================================


Informative: example.crt [ mycrtificat of website example.tk ]
Informative: example.key [ mykeyfile of website example.tk ]


5) Go to [ /home/example/ea-tomcat85/conf/ ] directory, There you should find a server.xml file.

6) Use the command [ cat /home/example/ea-tomcat85/conf/server.xml | grep "<Connector port=" ] to grep the server.xml file. Find the protocol="HTTP/1.1" [<Connector port="XXXX" protocol="HTTP/1.1""], It should look something like this which is need to commed manually

Find and comment or remove the line as below and remember connector port="10016"
#====================================#====================================
<!--
<Connector port="10016" protocol="HTTP/1.1" connectionTimeout="20000" xpoweredBy="false"/>
-->
#====================================#====================================

And append below parameters

#====================================#====================================
<Connector port="10016" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="10052" />
<Connector port="10052" protocol="org.apache.coyote.http11.Http11Protocol" SSLEnabled="true" scheme="https" secure="true" sslProtocol="TLS" keystoreFile="/home/example/ea-tomcat85/tomcat_ssl/mycert.p12" keystoreType="PKCS12" keystorePass="123456789"/>
#====================================#====================================

Informative: keystorePass="Yourpassword"
Informative: keystoreFile="/home/example/ea-tomcat85/tomcat_ssl/mycert.p12 [location of .p12 file ]
Informative: redirectPort="10052" [SSL redirection port always use new like 10053 or 10054 if any tomcat running on it already]


7) Finally restart the tomcat server using command [/scripts/ea-tomcat85 all restart ]

#====================================#====================================
/scripts/ea-tomcat85 all restart
#====================================#====================================

check the website over browser https://example.tk

If you want to redirect the domain to https automatically then follow below steps.

1) Go to /home/example/ea-tomcat85/conf/ directory, There you should find a server.xml file.
2) Use the command cat/vi/nano web.xml to view the server.xml file. Find the <web-app> </web-app>. It should look something like this and append below parameter

#====================================#====================================
<security-constraint>
<web-resource-collection>
<web-resource-name>Protected Context</web-resource-name>
<url-pattern>/*</url-pattern>
</web-resource-collection>
<!-- auth-constraint goes here if you requre authentication -->
<user-data-constraint>
<transport-guarantee>CONFIDENTIAL</transport-guarantee>
</user-data-constraint>
</security-constraint>
#====================================#====================================


3) Finally restart the tomcat server using command [/scripts/ea-tomcat85 all restart ]

#====================================#====================================
/scripts/ea-tomcat85 all restart
#====================================#====================================
