ARTH task - 7.1

Task 7.1 :-đź”…Increase or Decrease the Size of Static Partition in Linux.


Step 1 :-
     creating a hard disk of 8 GB and partition it into 5 half and formatting the hard disk or device , then you have to mount the device to the datanode directory and then connect the directory with the Data Node directory.

 






Now we have to check whether it is added or not :-



Now we will be creating partition in the disk /dev/sdb :-





Now format the device :-


Now we have to mount the to the datanode directory :- mount /dev/sdb4 /dn

Step 2 :-
        Configure the Name Node and Data Node for Hadoop cluster Prerequisite :-
                                     Java(jdk) and hadoop-software
        Configuring Name Node :- 
                       to install jdk and hadoop use rpm -i software_name --force (--force is used to
forcibly install the software)

a) configure the hadoop :

    

- update the content in hdfs-site.xml and core-site.xml as follows

- create a directory using mkdir /nn




B) Configuring Date Node :-

- to install jdk and hadoop use rpm -i software_name --force (--force is used to forcibly install the software)

- configure the hadoop


- update the content in hdfs-site.xml and core-site.xml as follows

- create a directory using mkdir /dn




Step3 :
        Format the Namenode directory

A) hadoop namenode -format 


Step4 :-
        Now start the Name Node and Data Node service



Step5 :-
        To check the total node joined use


Step 6 :-
         Unmount the partition from the /dn folder

A) unmount /dev/sdd1 /dn :-


Step 7 :- 
            Create the existing partition





Step 8 :-
            Create that partition again with the changed size

As we have to resize the partition we will create the partition ,but the major drawback is that we can’t change it on the fly , we have to unmount but the best part our data will not be lost






Step 8:- 
            Verify partition consistency with the e2fsck command

In this step, we will verify the partition consistency by running the Following e2fsck command : 
                                     e2fsck -f /dev/sdd1




That's all for today guy's keep learning and keep sharing. thankyou for your patient learning and have a nice day ahead.

  Introduction JavaScript is a programming language used primarily by Web browsers to create a dynamic and interactive experience for the user. Most of the functions and applications that make the Internet indispensable to modern life are coded in some form of JavaScript. The earliest incarnations of JavaScript were developed in the late 1990s for the Netscape Navigator Web browser. At the time, Web pages were static, offering little user interaction beyond clicking links and loading new pages. For the first time, JavaScript enabled animation, adaptive content and form validation on the page. JavaScript did not become standardized and widely adopted until 1999. Even after standardization, browser compatibility remained an issue for over a decade. JavaScript is used in almost every domain Web Applications Web Development Mobile Applications Server Applications Web Servers What is JavaScript used for?

TASK 12 DESCRIPTION - Use Ansible playbook to Configure Reverse  Proxy i.e. Haproxy and update its configuration  file automatically each time a new Managed node  join the inventory.  Proxy i.e. Haproxy and update its configuration  file automatically each time a new Managed node  join the inventory Configure the same setup as 12.1 over AWS  using instance over there . REVERSE PROXY In computer networks such as the internet, a reverse proxy is a common type of proxy server that is accessible from the public network. Large websites and content delivery networks use reverse proxies –and other techniques– to balance the load between internal servers. The reverse proxy becomes a single point of entry for the different web applications in the organization. The web servers stay hidden and thus protected from the Internet. Security monitoring such as log review can be performed from a single point. Configuring Haproxy via Ansible Playbook First, we have to ge...
