The national unified support system platform is

1. National credit information sharing platform: In order to realize the decision and deployment of the Third Plenary Session of the Eleventh Central Committee of the Communist Party of China, 18 Central Committees have established a unified platform, social credit data, and national credit information sharing platform It was officially launched in October 2015.

2. Unicom cbss refers to China Unicom cBSS centralized business support system. China Unicom's cBSS system realizes the core system concentration of BSS (Business Support System) domain.

3. The CBSS system can effectively improve customer perception and create value. A national system makes remote services and cross-regional services easy and simple. With the support of cBSS system, mobile phone business hall and online business hallElectronic channels can give users a better experience, and offline physical channels can realize supermarket acceptance and electronic services.

4. The ministerial-level mobile application platform should be under the guidance of the overall framework of the national comprehensive transportation information platform, and should form a "six unified" overall framework in terms of technical architecture, namely: unified platform entrance, unified support system, unified information resources, unified basic conditions, unified security prevention and control, unified access Service.

Linux operation and maintenance tool linux operation and maintenance tool

HTop is an interactive process browser under Linux, which can be used to replace the TOP command under Linux . NMON: System Resource Monitoring NigEls Monitor, abbreviated as nmon, is a common tool developed by Nigel Griffiths to monitor the performance of Linux systems.

The position of Shell script in Linux operation and maintenance. The Shell scripting language is very suitable for processing data of plain text types, and almost all configuration files and log files (such as NFS, Rsync, Httpd, Nginx) in the Linux system , LVS, MySQL, etc.), and the vast majority of startup files are plain text type files.

The monitoring of Linux by SUM server monitoring software is one of the most basic functions of SUM.

The tools are as follows: Linux system foundation, is the foundationThe basics in the middle, reference books, you can read the basic chapter of Bird Brother Linux, and at least master 80% of the content of this book. You don't have to master all of it, but you have to know the basic commands.

The one with ※ has been used more for old boys in recent years, and it can be trusted. It is also the mass of Linux operation and maintenance in recent years. 3) With the function classification and software name, if you have any needs, you can find the software directly by function.

What are the main functional features of python automated operation and maintenance monitoring system architecture

Fast development speed and high efficiency Python is known as the "glue language" and has a rich and powerful library that can realize many powerful functions. Therefore, Python runs very fast and the development efficiency is very high.

It can help handle various tasks, including regular expressions, document generation, unit testing, threads, databases, web browsers, CGI, FTP, email, XML, XML-RPC, HTML, WAV files, password systems, GUI (graphical user world Surface), Tk and other system-related operations.

Features of python language Simple and easy to learn Fast speed: The underlying layer of Python is written in C language, and many standard libraries and third-party libraries are also written in C, and the running speed is very fast.

Automated operation and maintenance automates the operation and maintenance work, which can free the operation and maintenance personnel from the management of the server, making the operation and maintenance work simple, fast and accurate. Embedded application development, game development and desktop application development.

Definition of automated operation and maintenance system Automated operation and maintenance system is a way to use automation technology to realize IT system operation and maintenance. It can realize automated deployment, automated monitoring, automated alarm, automated backup and other functions, thus reducing manual intervention and improving operation and maintenance efficiency.

What tools do you need to master in system operation and maintenance?

1. Server security and monitoring zabbix is a monitoring tool that supports snmp and custom templates, which can monitor business-level indicators. TenableNessus, IDS, IPS and other tools can be used for security monitoring.

2. Monitoring tools have their own focus. Zabbix supports snmp and its own agent at the same time, and also supports custom templates, which is a good choice in most scenarios. In addition, don't think that zabbix can only monitor server information. Through custom templates, you can also monitor business-level indicators.

3. The technologies that need to be mastered for operation and maintenance are: Linux system foundation, network service, shellL Script and another script language, sed and awk tools, text processing commands, database, database, monitoring tools, cluster and hot backup, data backup.

4. System installation automation questions: kickstart, answer cobbler, etc. Configuration and deployment automation: puppet, saltstart, ansible, etc. Monitoring version (alarm) automation: Nagios (monitoring system), ganglia (cluster monitoring), cacti (flow monitoring), ipmonitor (ping monitoring), etc.

5. The tools are as follows: Linux system foundation is the foundation of the foundation. For reference, you can read the Linux basics of Brother Bird. At least 80% of the content of this book should be mastered. You don't have to master all of them, but you must know the basic commands.
