Chapter 5. Installation

d.Edit the /etc/sysconfig/iptables file and add the following lines at the beginning of the INPUT chain.

-A INPUT -p tcp --dport 3306 -j ACCEPT

7.Return to the root shell on your first Management Server.

8.Set up the database. The following command creates the cloud user on the database.

•In dbpassword, specify the password to be assigned to the cloud user. You can choose to provide no password.

•In dbhost, provide the hostname or IP address of the database node.

•In deploy-as, specify the username and password of the user deploying the database. For example, if you originally installed MySQL with user “root” and password “password”, provide--deploy-as=root:password.

•(Optional) For encryption_type, use file or web to indicate the technique used to pass in the database encryption password. Default: file. See Section 5.4.5, “About Password and Key Encryption”.

•(Optional) For management_server_key, substitute the default key that is used to encrypt confidential parameters in the CloudPlatform properties file. Default: password. It is highly recommended that you replace this with a more secure value. See Section 5.4.5, “About Password and Key Encryption”.

•(Optional) For database_key, substitute the default key that is used to encrypt confidential parameters in the CloudPlatform database. Default: password. It is highly recommended that you replace this with a more secure value. See Section 5.4.5, “About Password and Key Encryption”.

#cloudstack-setup-databases cloud:<dbpassword>@<dbhost> --deploy-as=root:<password> -e <encryption_type> -m <management_server_key> -k <database_key>

9.Now run a script that will set up iptables rules and SELinux for use by the Management Server. It will also chkconfig off and start the Management Server.

#cloudstack-setup-management

10.Continue to Section 5.4.7, “Prepare NFS Shares”.

5.4.5. About Password and Key Encryption

CloudPlatform stores several sensitive passwords and secret keys that are used to provide security. These values are always automatically encrypted:

•Database secret key

•Database password

•SSH keys

•Compute node root password

4.2 specifications

Citrix Systems, a leading provider of virtualization solutions and cloud computing technologies, released version 4.2 of its popular software, Citrix XenApp, which was previously known as Presentation Server. This version marked a significant evolution in providing users with remote access to applications and desktops, emphasizing simplicity, performance, and security.

One of the standout features of Citrix XenApp 4.2 is its improved application streaming capabilities. This technology allows applications to be delivered to users in real-time, reducing the need for extensive local installations and enhancing the user experience. With application streaming, administrators can efficiently manage applications on a central server while ensuring that users have immediate access to the necessary tools.

Another highlight of this version is the enhanced security measures put in place to protect sensitive data. Citrix XenApp 4.2 includes support for SSL encryption, providing a secure communication channel for data transmitted between the server and clients. This is particularly crucial for businesses that need to comply with strict data protection regulations. Additionally, the integration of endpoint security features ensures that unauthorized access to applications is minimized.

Performance enhancements are also a critical focus in this release. Citrix optimized the delivery of applications over various network conditions, ensuring that users experience minimal latency regardless of their location. This was achieved through the incorporation of SmartAccess and SmartControl technologies, which allow administrators to set policies based on user roles, device types, and network conditions. This level of granularity enables organization-wide security without compromising on usability.

The user experience was further improved with a revamped interface, making it easier for end-users to access their applications and data. Simplified menus, clear navigation paths, and the ability to customize user settings contributed to a more efficient workflow, allowing users to focus on their tasks rather than struggling with the software.

Finally, Citrix XenApp 4.2 was designed to be highly scalable. Organizations of all sizes could deploy this solution to deliver applications efficiently, adapting to their specific needs as their user base grows or changes. This flexibility is crucial for businesses looking to future-proof their IT investments while maintaining optimal performance.

In summary, Citrix XenApp 4.2 stands out with its enhanced application streaming, robust security features, improved performance under varying conditions, user-friendly interface, and scalability, making it an ideal choice for organizations seeking to leverage virtualization for remote access to applications and desktops.
