The fourth stage: advanced system management and automation tools for operation and maintenance.

CentOS system startup process, GRUB detailed explanation, Linux kernel, CentOS system installation, bash script programming, ansible, zabbix monitoring system

Phase 5: technical architecture and implementation of large-scale sites

Evolution of large website architecture, architecture model and core elements of large website, NLB Cluster, high performance caching service varnish, high performance architecture of website, high availability cluster keepalived, high availability architecture of website, distributed storage mogilefs, mysql, redis of NoSQL system, scalability architecture of website, kvm virtualization technology, elk, container technology docker

To sum up and learn Linux, the following knowledge points must be mastered:

1. Basic configuration of the operating system.

Including the network, hostname and other settings, to put it bluntly, is to continue to install the system, and after the installation of the operating system can make it normal Internet access, usually these configurations can be specified when installing the operating system.

two。 Specific network configuration and parameters.

Basic network knowledge is really necessary, such as what is the IP address? What is the purpose of the subnet mask? What does the gateway have to do with routing? To tell you the truth, many college students can't say it now, even though they use the Internet every day. On the other hand, the network configuration of Linux is relatively free. if you are not careful, the network may be cut off. for example, after using the ifconfig command, the network will take effect immediately.

3. Linux operating system partition management, file management related commands.

One of the main functions of the operating system is to manage the file system, such as new, open, copy, delete, move, and modify files.

4. A proficient editor.

For example, VIM under CLI, gedit under graphical interface, etc.

5. Various common Linux commands.

This one is more complicated, and you can learn it slowly in use.

The above is the introduction of the knowledge points of the linux system shared by the editor. If you happen to have similar doubts, you might as well refer to the above analysis to understand. If you want to know more about it, you are welcome to follow the industry information channel.
