Installing CentOS Considerations

01. Install CentOS with minimal installation Select Development Tools option for system installation, root password using 16-bit

02. Modify the SSH Ports/etc/ssh/sshd_config port 1433 (1433 is Microsoft's SQL connection port)

03. Turn off root telnet mode/etc/ssh/sshd_config (Permitrootlogin No)

04. Create jumper user, log in to Linux with jumper user, and su root switch to root for software installation and other work

05. Use the feature account for service deployment to avoid mis-operation at deployment time.

06. Set up the iptables to do port management

07. Deploy denyhosts to prevent the root password brute force hack of the public network to the machine

08. Deploy the ClamAV tool for virus scanning of Linux files

09. Deploy Zabbix-agent to add monitoring items

So much has been summed up so far.
