This article mainly introduces the relevant knowledge of how to maintain the Linux/Unix server, the content is detailed and easy to understand, the operation is simple and fast, and has a certain reference value. I believe you will gain something after reading this article on how to maintain the Linux/Unix server. Let's take a look at it.

Daily maintenance of server hardware maintenance-expansion of storage equipment

As resources continue to expand, the server needs more memory and hard disk capacity to store these resources. Therefore, the expansion of memory and hard disk is very common. Before adding memory, you need to determine the compatibility with the original memory of the server, preferably the same brand of memory. If it is server-specific ECC memory, you must choose the same memory. The use of ordinary SDRAM memory on the same server as ECC memory is likely to cause serious errors. Before adding a hard disk, it is necessary to determine whether the server has a spare hard disk bracket, hard disk interface and power interface, and whether the motherboard supports a hard disk of this capacity. Special attention should be paid to avoid buying equipment but not being able to use it.

Daily maintenance of server hardware maintenance-uninstallation and replacement of equipment

It is not a big problem to uninstall and replace the equipment. It should be noted that many brand server chassis are specially designed and need special tools or mechanisms to open. When unloading the chassis cover, you need to read the instructions carefully and do not disassemble them forcibly. In addition, this must be done with a complete power outage and a well-grounded server, even for hot-swappable equipment to prevent damage to the equipment caused by static electricity.

Server daily maintenance common sense hardware maintenance-dedusting

Dust is the biggest killer of servers, so you need to dust the servers on a regular basis. For servers, dust can even be fatal. The dedusting method is the same as the ordinary PC dedusting method, especially the power supply dedusting.

Server daily maintenance software maintenance-operating system maintenance

The operating system is the software foundation of the server, and its importance is self-evident. Most server operating systems use Windows 2003 or Windows 2008Server as the operating system, which is relatively easy to maintain. Open the event Viewer in Windows NT or Windows 2003 Server and check the system log, security log, and application log for any special exceptions. Now there are more and more hackers on the Internet, so we need to download the latest Service Pack (upgrade service pack) installation on Microsoft's website and fix the security loopholes in time.

Daily server maintenance software maintenance-maintenance of network services

There are many network services, such as WWW service, DNS service, DHCP service, SMTP service, FTP service and so on. With more and more services provided by the server, the system is easy to be confused. At this time, it may be necessary to reset the parameters of each service to make it run normally.

Server daily maintenance software maintenance-database service

After a long-term operation of the database, it is necessary to adjust the performance of the database to make it optimal. The data in the database is the most important, if these databases are lost, the loss is huge, so you need to back up the database regularly, just in case.

Server daily maintenance software maintenance-user data

After frequent use, the server may store a large amount of data. These data are very valuable resources, so they need to be sorted out, carved into a CD and stored permanently, so that the data can be recovered even if the server fails. Installation and configuration upgrade of server environment configuration Apache,IIS,PHP, JSP, database, extension components, etc.

8 common sense necessary for server maintenance

Server security configuration, WEB server environment building, other application installation and configuration, website security detection and cleaning, antivirus software, firewall installation, data backup, program upgrade, migration, etc., responsible for all aspects of technical processing and daily maintenance of your server and website, ensuring security + stability + 24-hour technical support within one year (except website program code modification and content update)

Linux/Unix server maintenance

1. Unix server maintenance (the server is fully maintained by us, and it is also the most reassuring service for you) Unix server security configuration, WEB server environment configuration, other application installation configuration, website security detection and cleaning, antivirus software, firewall installation, data backup, migration, program upgrade, etc. Responsible for all aspects of your server and website technical processing and daily maintenance (except for website program code changes and content updates).

2. WEB server environment configuration Apache,PHP, MySQL,Zend, installation and configuration upgrade of all kinds of components. For example: installation, configuration and optimization of LAMP (linux+apache+mysql+php) environment; installation and optimization of nginx+mysql/sqlserver+Resin environment; installation, configuration and optimization of apache+mysql/sqlserver+tomcat environment; installation, configuration, maintenance and optimization of mysql and postgresql databases and database synchronization settings

3. Installation and configuration of other applications install and debug other programs and upgrades according to customers' special needs; configuration, maintenance and optimization of postfix mail server; installation and optimization of VPN dedicated line dial-in; construction of intelligent DNS step-by-step parsing system; configuration, maintenance and optimization of various load balancing, cluster and dual computers

4. PHP website security detection and horse cleaning Unix system security loopholes detection and repair after being hacked, cleaning Trojan back door and other measures, firewall configuration, mainly for independent websites.

5, Unix server emergency remedy after the windows server system crash, the server is attacked first aid, the website is invaded after the emergency removal of Trojans, backdoors, security settings, program migration.
