Data center migration, the server maintenance daily need to do what work?

The data center migration in recent years, network data security is becoming more and more important, server maintenance has been paid more and more attention, and in the maintenance of the server must be careful to handle the daily maintenance work, otherwise the error will affect a little big. So, what does the server need to do?

First, software maintenance
1. Database services
After long-term operation of database, database performance needs to be adjusted so that it can enter the optimization state. The data in the database is the most important, if the data is lost, the loss is very huge, so it is necessary to regularly backup the database, just in case.
2. Maintenance of operating system
Operating system is the software foundation of server operation, and its importance is self-evident. Most server operating systems use Windows 2003 or Windows 2008 Server, which is easier to maintain.
Open event viewer on Windows NT or Windows 2003 Server, and see if there is any unusual exception in the system log, security log, and application log. There are more and more hackers on the Internet, so you need to download the latest Service Pack (upgrade service package) on Microsoft's website, and make up for the security vulnerabilities in time.
3, user data maintenance
The server after frequent use, can store a large amount of data, these data is a very valuable resource, so need to be sorted, and carved disc permanent saved, even if the server fails, can restore the data.
4, network service maintenance
There are many servers in network services, such as WWW service, DNS service, DHCP service, SMTP service, FTP service, with more and more services provided by the server, the system is easy to confusion, you may need to set the parameters of each service, so that normal operation.
Two, hardware maintenance
1, regular dust removal
Dust is the server's biggest killer, so you need to periodically dust the server. For the server, the dust is very lethal, it will seriously affect the service life of the server, dust removal method and the common PC dust removal method is the same, especially pay attention to the power supply dust.
2. Storage equipment expansion
As resources continue to expand, servers need more memory and hard disk capacity to store these resources. So memory and hard disk extensions are very common. Before adding memory, it is necessary to identify the compatibility with the original memory of the server, preferably the same brand of the same memory. If the ECC memory is dedicated to the server, then the same memory must be used. The common SDRAM memory and the ECC memory are used on the same server, which may cause serious errors. Before adding the hard disk, it is necessary to determine whether the server has a spare hard disk support, a hard disk interface and a power interface, and whether the motherboard supports the hard disk of this capacity. In particular, it's important to avoid buying equipment and not using it.
3. Regularly replace and uninstall equipment
Not unloading and replacement of equipment when the problems need to pay attention to is the design of many brand server chassis is special, need special tools or authority to open, when unloading the chassis cover, need to carefully read the instructions, do not forcibly remove. In addition, it must be carried out under the condition of complete power off and good grounding of the server, even the equipment supporting hot swap, so as to prevent the static electricity from damaging the equipment.
