I have a web based system in php that works locally in multiple places and in each place has a local database in mysqli.
Also my system in every place connect remotely to another database that get all of information from specific tables of local systems as an example when you insert a record in any place,this record insert to remote database ,too. and so on ,to tell summary sync information from local to remote database.
schema of the system
Now I know replication can be a good idea for this.
but I don't know when my remote database has a problem and my system can't connected to remote database how to apply changes in local database to remote database?

I have a situation wherein I want to sync remote and local MYSQL databases.
Local DB is connected to local application and remote DB is connected to remote application.
So records in both DB get updated or inserted separately.
Database schema is same.
What is the best option to keep both databases in sync?
A web application runs both on live and local server with live and local database server. Users use live server to add the data, whereas internal staffs use the local application to update the data. After some time, both of these databases have to be synchronized properly without loss of data from live or local database server. I don't want an exact replica of live database in local database or vice-versa but databases need to synchronize values which have been entered in it.
I am having a MySQL database in my local machine (in XAMPP) that I access using phpmyadmin. I also have a website hosted on Godaddy. I generally stay offline and make changes into data stored into database.
I want to know how can I auto replicate the changes in local database to the one in Godaddy's server or can replicate using click of a button.
I have seen some answers that told about replication but I am unable to replicate data from my local machine to the Godaddy's server.
Can anyone please tell me the steps to replicate database in simplest way.
Thank you in advance!
After lot of searching and learning, I finally found an answer to this question.
On shared hosting, Godaddy do not provide access to the configuration files of mysql (my.ini). So the replication of data is not possible using master slave replication from local(master) to remote(slave) MySQL.
The only thing that can be done is, one can create a log file of all the data that are being entered into database while the user is offline (maybe a XML file) which contains the data that is not transfered to the global database, and can upload the file when connected to the internet and parse the XML to send data to the global database.
My MySQL database (local server) is connected to a weather station. The data are updated continuously on my local server. My idea is to develop a web application that allows me to access this data.
My local database (MySQL) has to be replicated on a remote server (phpmyadmin)
The architecture is as follows:
My questions are:
1- How I do the connection ? I know that I can import my cvs file manually but I don't want to do this.
2- Can I update the datas automatically in my remote server ?
NOTE: I only want to queries on my remote server (phpmyadmin), I will not create or modify new datas.
Thanks you for your help.
As i understood, you want to make a copy of your local mysql data on a remote server.
first of all phpmyadmin is a tool or webapp to access mysql , it is not a server itself.
and second
there are two type of replication approach
Master-slave (read from slave , write to master, that will sync to slave)
How to do it
Master- Master (whatever operation are on master that will also replicate on other master) How to do it (Master-Master replication is deprecated. See Group Replication as a replacement)
You can choose the approach as per your requirement
Master-master vs master-slave database architecture?

I have two databases. One is on local server and the other is on a production server. I'm continuously working on the local server and after approval I want to update production server. Wih the current setup, I need to take dump or copy or export of database and then import into production database, every time. Is there any way of synchronization method in phpmyadmin for database on different server.
It is possible to synchronize a model in MySQL Workbench with a live database?
Other then this, how can I do this? I'm able to use queries, the command line and phpmyadmin itself.
Please specified any simple method.
The "synchronisation" feature you are looking for is called replication. A replication can be set up between a master and a slave machine. It does not rely on a constant connection, but stores all changes on the master and replays all those changes on the slave once a connection is established.
