Finally, it is found that the most important problem is the communication between development and operation.

Saltstack is a centralized server infrastructure management platform with configuration management, remote execution, monitoring and other functions, can be understood as a simplified version of the Puppet, which is based on the Python language implementation, combined with lightweight Message Queuing (ZeroMQ) and Python third-party module building. Has the following characteristics:

Simple deployment, convenient support for most unix/linux and Windows environments Master-slave centralized management configuration is simple, powerful, scalable, strong, and controlled certificate-based authentication, secure and reliable support API and custom module, can be easily extended by Python By deploying the Saltstack environment, we can perform batch commands on thousands of servers, configure centralized management according to different business features, distribute files, capture server data, operating system fundamentals, and package management, so Saltstack is the operator to increase productivity, Standardize the business configuration and operation of the sharp weapon. (Of course, as a developer, my goal is not just that) below are some specific:

The following are common modules for Saltstack:
(1) Archive module function: To achieve the system level of compression package calls, support Gunzip, gzip, RAR, tar, Unrar, unzip and so on. (2) CMD module function: Implement remote command line call execution (default root operation, use need to evaluate risk). (3) CP module function: Realize remote file, directory replication, and download URL files and other operations. (4) Cron module function: Realize the crontab operation of the controlled host. (5) Dnsutil module function: To achieve the host with the use of DNS-related operations. (6) File module is controlled by the host files common operations, including file read and write, permissions, find, check and so on. (7) Iptables module function: Controlled host iptables support. (8) Network module function: Return to the host net information. (9) PKG Package Management module function: Controlled host package management, such as Yum/apt-get. Service Module Features: Managed host package services. (11) Other modules are also provided with user (System user module), group (System Group module), partition (System partition Module), Puppet (Puppet Management module), System (reboot, Shutdown module), TimeZone (Time zone management module), Nginx (Nginx Management module), mount (file system mount module), etc.
Of course, you can also customize the module
