Explain the process of installing and configuring application software.

7.Explain the process of installing and configuring application software.
Ans.
1. Installing a software basically means copying a set of code in specific directory from which system can access those files for compilation and execution.

2. New software packages might be installed in ‘/opt’ if they are likely to be upgraded separately from Red hat distribution itself.

3. Some packages may need to go in ‘/usr/src’ or even ‘/usr’ if they are upgraded of packages installed as part of packages installed as part of Red hat.

4. The location of the installation usually matters only if you compile the application from source code.

5. If you use a Red hat package manager (RPM) application package, it automatically goes where it should.

6. It is possible for individual users to install some applications in their home directories.

7. Drive space set aside for their own files and customizations, these applications may not be available to other users without the permission of the user who installed the program or the system administrator.

8. Besides system administrator can decide which users may use which application by creating a ‘group’.

69.How to configure Network file system version 4 (NFSv4) client? Ans. 1. There are two new options listed in NFSv4 are introduced as: clientaddr and ports 2. The version 3 of NFS introduced NFS over TCP, which improved NFS’s reliability. 3. In NFSv3, users use the mount option i.e., tcp as client whether client wants to use TCP or UDP to communicate with the server. NFSv4 replaces tcp or udp with a single option i.e. ports=tcp or udp 4. The default buffer size for NFSv4 is 8192 bytes, but it can grow to as large and by 32,678 bytes, which results performance improvements. 5. Following are the mount options: clientaddr=n – Declares client to be multihomed proto=type – Declares port as either udp or tcp resize=n – declares read size of clients buffer wsize=n – Declares write size of clients buffer sec=mod – Declares security model as either krb, krb5 etc.
