Php+shell-Based publishing system

I. Issues to be addressed by the publishing system

A more complete publishing system must first be able to publish files, and secondly, when the issue of issues should be able to support the revocation, to avoid long time cannot solve the problem affecting the normal operation of the product.
For publishing scripting languages such as Php,shell join syntax checking, there are syntax errors preventing this release.

Two. Principle

We are using the publishing system based on Php+shell development, the release of the time to fill out the file list, from the current machine A to target machine B, before the release of a machine through the SSH protocol authentication login to the B machine execute shell command backup file list to be published
Then use rsync to synchronize the file list from the A machine to the B machine, write the current release record to the database when it is finished, and overwrite the corresponding backup file to the B machine when the rollback is needed.

Three. The problem to be resolved

1. Using rsync and backing up the target machine files requires a password-free login

A machine to B machine to achieve a password-free login, you need to use Ssh-keygen to generate the current user's login key, the current user's public key is appended to the target machine user's. ssh/authorized_keys file
The following shell is the Authorized_keys file that appends the public key of the current machine to the target machine

user=wwwip=192.168.1.100 #B机器ipPORT =22 #B机器SSH协议端口cat/home/${user}/.ssh/id_rsa.pub | SSH ${user}@{ip} ' cat>>/home/{$USER}/.ssh/authorized_keys '

Follow-up without entering the password can be in a machine-free login B Machine

2. Publish to more than one machine
If the target machine has multiple units, it can be circulated to the target machine. If the file is too large for each update, it can be published to a central node server and then synced to other machines using Sersync. Https://code.google.com/archive/p/sersync/downloads
Modify the CONFIG. rsync node <ssh start= "True"/>, and use the password-free user to start the Sersync service
