This article mainly explains "what is synchronizing the online server code to the web node script". The content of the article is simple and clear, and it is easy to learn and understand. Please follow Xiaobian's train of thought to study and learn what the synchronization online server code to the web node script is.

Shell provides a way for you to communicate with the operating system. This communication can be performed interactively (typed from the keyboard with an immediate response) or as shell script (non-interactive). Shell script is a string of shell and operating system commands placed in a file that can be reused. Essentially, shell script is a simple combination of command-line commands into a single file.

Record a small example of a shell script, and the online server synchronizes the code to the web node script.

#! / bin/bash#author:21yunwei c = "$1"; if ["$c"! = "1"]; then echo "EXIT"; exit;fi

# define web node pool

Webnode= (21yunwei-web121yunwei-web221yunwei-web321yunwei-web4)

# synchronize data cyclically, updating from the test site directory to the official site directory

For host in ${webnode [@]} doecho "rsync data to $host" rsync-avz-P-e ssh / wwwroot/21yunwei-prelive/* $host:/wwwroot/21yunwei/doneret=$?if [$ret-eq 0] then echo "$1 synchronization completed" else echo "$1 synchronization failed, please check" fi "

Suppose the script name is: rsync_to_web.sh

Usage
