In 2022 March ,when our house gas finish,we were unable to buy new gas,due to Sri Lanka economy failure after covid 19 pandamic situation.Then I search for other options.
Then I found this Coconut shell charcoal cooker.
It need 8 kg of cocount shell every week for my home.My home there are 5 members.
It's main row material is coconut shell.
We need to create all the curry and once.
Then start the cooker.
It's best option for cooking with out gas.
first check whether machine has Angularjs install
ng --version
ng new hello-world

1. create ssl folder
sudo mkdir /etc/nginx/ssl
2. go to nginx /ssl folder using below command
cd /etc/nginx/ssl 3.The first file that we need to create is the private key. While creating the key, we will be asked for a passphrase. We must make sure to remember the passphrase since we will not be able to access the certificate without it. sudo openssl genrsa -des3 -out server.key 1024
4.
Once we have the key created, we will use the key on order to create Certificate Signing Request. 5.We have to run below command to create certificationsudo openssl req -new -key server.key -out server.csr It will ask your old pass pharse value and Company Name,City like wise Questions.you may refer screenshot.
6.If we have a passphrase it has to be typed in manually, so if there is not person available to do it, the website will be offline for a long time. That is why we are going to remove the passphrase from the key file, using the following command # sudo cp server.key server.key.org
# sudo openssl rsa -in server.key.org -out server.key
7.Now we are ready to create and sign our certificate by below command
sudo openssl x509 -req -days 365 -in server.csr -signkey server.key
8.
It will be valid for 1 year (365 days). That is something that can be
changed if needed. Now we can use the certificate and assign to a
virtual host. We can copy the Nginx sample configuration file in a new
file and use that. 9.most important part to be change are as followsserver {
listen 443;
server_name our-domain.com;
root /var/www;
index index.html index.htm;
ssl on;
ssl_certificate /etc/nginx/ssl/server.crt;
ssl_certificate_key /etc/nginx/ssl/server.key;
} After making the changes and saving the file, we should copy the virtual host configuration file into /etc/nginx/sites-enabled/default file.
Before change it ,please take a backup of it.
and then restart Nginx.
# sudo service nginx restart
1. go to https://www.jetbrains.com/idea/download/#section=linux

4. After that open Visual STudio Code IDEThen Add Simple React Snippets ExtensionExtension
Now you can run reactjs project on your Ubuntu machine.Good luck1. install jdk 8 or open jdk 8
2. create tomcat user account
sudo groupadd tomcat
3. run below command
sudo useradd -s /bin/false -g tomcat -d /opt/tomcat tomcat
4. move to tmp folder
5. run the below command to download tomcat tar file
wget ftp://apache.cs.utah.edu/apache.org/tomcat/tomcat-8/v8.5.68/bin/apache-tomcat-8.5.68.tar.gz
6. create folder on /opt/tomcat
cd /opt/
sudo mkdir /opt/tomcat
7. run below command - to extract tar file to /opt/tomcat
cd /tmp/
sudo tar xzvf apache-tomcat-8*tar.gz -C /opt/tomcat --strip-components=1
8.tomcat extract to below folder
9.give the tomcat user control of the entire directory and make all the scripts in the bin location executable
sudo chown -R tomcat: /opt/tomcat sudo sh -c 'chmod +x /opt/tomcat/bin/*.sh'
10.run below command
sudo vi /opt/tomcat/conf/tomcat-users.xml
add the below lines
11. add below line to
sudo vi /etc/systemd/system/tomcat.service
==============================

12. After that, run the commands below to reload systemd profiles and enable tomcat service
sudo systemctl daemon-reload
--- not working below two line ----------
sudo systemctl start tomcat.service sudo systemctl enable tomcat.service
13. run the tomcat using the below commands
sudo -s
cd /opt/tomcat/bin/
./startup.sh
14. on the web browser run below command
