Installing IMC-required packages
Installation preparation
H3C Intelligent Management Center (IMC) supports Red Hat Enterprise Linux (RHEL) operating systems, including RHEL 7.3, RHEL 7.4, RHEL 7.5, RHEL 7.6, and RHEL 7.9.
IMC on RHEL 7.x requires configuration during and after installation of the operating system. This document uses RHEL 7.4 as an example to illustrate the required configuration.
Hardware requirements
IMC runs on Linux and stores and manages data with Oracle databases. You must install the operating system, databases, and IMC software correctly.
Table 1 shows the hardware requirements and minimum configuration of IMC. The node count, collection units, and online operators columns represent the management scale, and the remaining columns represent the minimum system requirements. For the collection units column, a value range of 0 K to 5 K means performance monitoring is not enabled or a small scale of performance monitoring is enabled. To deploy service components, see the associated release notes for information about the hardware configuration requirements.

IMPORTANT: In this document, IMC is installed in the root directory. To install IMC to another partition, make sure the partition meets the hardware requirements in Table 1. As a best practice, reserve a minimum of 50 GB for the root partition. |

To improve server IO performance, follow these guidelines:
· If the number of collection units reaches 100 K to 200 K, install two or more disks and configure a disk RAID module of more than 256-MB memory.
· If the number of collection units reaches 200 K to 300 K, install two or more disks and configure a disk RAID module of more than 512-MB memory.
· If the number of collection units reaches 300 K to 400 K, install more than four disks and configure a disk RAID module of more than 1-GB memory.
· As a best practice, configure RAID5 (that requires three or more hard drives), more than four hard drives, and use RAID 0+1.
Preparing the installation CD
Installation requires the Red Hat Enterprise Linux Server 7.4 installation software suite and software serial number. Set the server to start up from the CD-ROM.
Collecting system information for installation
Collect system information to be used for installation, including the host name, IP address, and network connection information on the target server. You can obtain the IP address and network connection information from the network administrator.

5. Click DATE & TIME to modify the time zone setting. This example uses the default Americas/New York time zone, as shown in Figure 4.
Figure 4 Setting the date and time
6. On the installation summary page, click SOFTWARE SELECTION.
7. Select Server with GUI and the following options, as shown in Figure 5, Figure 6, and Figure 7:
¡ FTP Server
¡ Hardware Monitoring Utilities
¡ Java Platform
¡ KDE
¡ Performance Tools

Post-installation configuration
After installing the Linux system, complete the following configuration to correctly install and run IMC.
Disabling the firewall
1. Log in to Linux as a root user.
2. Disable the firewall.
systemctl stop firewalld.service
systemctl disable firewalld.service
3. Check the firewall state.
systemctl status firewalld.service
Disabling SELinux

vim /etc/selinux/config
2. Set SELINUX to disabled.
SELINUX=disabled
3. Save and close the file.
4. Restart Linux to validate the configuration.
Setting the number of file descriptors
1. Log in to Linux as a root user and view the number of file descriptors.
ulimit –n
2. Modify the value if it is smaller than 65535.
vim /etc/security/limits.conf
3. Add the following commands at the end of the file. If the commands already exist, make sure the values are greater than 65535.
* soft nofile 65535
* hard nofile 65535
4. Save and close the file.
5. Restart Linux to validate the configuration.
Setting the limit of user processes
1. Log in to Linux as a root user and modify the limit of user processes.
vim /etc/security/limits.d/20-nproc.conf
2. Change the default value to 40960.
* soft nproc 40960
root soft nproc unlimited
3. Save and close the file.
4. Restart Linux to validate the configuration.
Installing IMC-required packages
|
|
NOTE: · The software packages of RHEL 7.x are located in the Packages directory of the installation CD. · The software package version numbers might vary by RHEL version. · RHEL 7.x does not provide the compat-libstdc++-33 installation package. As a best practice for correct IMC operation, download it from the website. |
To ensure correct operation of IMC, install required 32-bit software packages on RHEL 7.4 with the root user privileges.
