Hi
Venkat Nagappan
I Installed Mysql cluser version 7.4.20. but when I use command mysql_secure_installation as I received an errror "Can't find a 'mysql' client in PATH or ./bin". Can you help me?. Thanks
Just amazing enlightening video for cluster setup. Would you share some thoughts on how would you setup a cluster for READS exclusively, and WRITES exclusively and update the writes done in write cluster to read cluster in one direction. I guess thats another setup for really really large scale may be like wikipedia where writes are relatively less than reads. Also I would like to know like whats the max concurrent reads that mysql stand for 1G Memory and 1 VCPU. and whats the max concurrent writes that mysql stand for 1G Memory and 1 VCPU.
15:22 is it "ServerPort 2202" or "ServerPort=2202" ?
That's a great demo i've ever seen. Thanks.
Excellent video, could you please also do a video demonstration of how to install /configure a load balancer for the MYSQL cluster on CentOS? is the same configuration as in your other video demo for Nginx ?
Excellent Video
Thank Nagappan. The best video of setting up MySQL cluster step by step I have never seen before.
Thank you very much. The document of MySQL is not so clear about the installation NDB on Linux, your video is very helpful.
Great demo. Thanks.
Excellent work. Thanks.
Thanks Venkat for this video tutorial. Can you please help me in setting up Mysql-Cluster on one centos7 machine? As I already tried many of tutorials explaining to setup MySQL Cluster on single machine but all left me in middle along with a lot of different issues.
Thanks for you help in advance!!
Amazing! Thanks!
Excellent presentation!
Excellent one. I have just followed the steps and done it. But I'm finding a problem on replicating the tables inside the DB. do you have any suggestions on that?
Fantastic demo. I'm not the DB guy, but this is very good hands-on for anyone to set it up. Thank you!
Hi Bro, I have a query that I am getting an error while entering 'ndb_mgmd -f /var/lib/mysql-cluster/config.ini'
-bash: ndb_mgmd: command not found
How can this be overcome.
Thanks for adding, a clear concise demo.
At 38:30, you should use the flush privilege command in host cenvm02. No need to drop the user and recreate it. 🙂
Excellent video, hitting the snags along the way is a great way to show how it all works, well done
Excellent tutorial. Last year, I had tried this setup successfully on vagrant vm's based on your tutorial. Now I tried the same on digitalocean droplets (512MB) and could not get it working due to out of memory errors. Venkat, do you have recommendations on minimum system requirements for this architecture?
Excellent Videos Venkat on MySQL Replication. Their is one request from my side if you get time can you please make a video on "Multi-Master Replication Manager for MySQL".
beautiful explanation! we need to have professors like you in universities.
really wonderful knowledge share.
Nice video, very well explained. Thankyou.
can you help about synchrouniztion of mgm ,dbnode ,sqlnode
Perfect Video !
very nice demo, except the title: it is not "easy", atleast not that easy.
Super
You can easily rely on service/systemctl scripts when starting SQL nodes via "service mysql start" instead of mysqld_safe, all you need to do is enable port 2202 in selinux for mysqld_port_t object.
Nice tutorial anyways.
