It's very easy.

How to solve the problem "The server is not configured properly to be an active member of the group" First of all, thank you very much for this video. I found it very useful. If the UUID is the same, it doesn't work. To change the UUID on nodes 2 and 3 Simply remove sudo rm /var/lib/mysql/auto.cnf Restart the mysql service and a new UUID is automatically generated

Installing nvidia drivers have a high chance of bricking your linux install

everything i did, but its getting connection time out error(mount.nfs: Connection timed out for 44.223.69.228:/exports/backups on /mnt/backups). and my ubuntu firewall(ufw) is in inactive state and in my aws i have given permission to Allow all traffic. Can you help me with this.

good luck using nvidia drivers with kernel 6.12

Seems like the file containing the hosts is missing

Welp time to sign off kernel modules for the millionth time

Didn't work on Ubuntu 20.04. To under: sudo add-apt-repository --remove ppa:mrazavi/gvm && sudo apt-get update && sudo apt autoremove --purge gvm && sudo apt install --fix-broken -f

Bro your the best thank you 🎉🎉 you got a new sub

this guy is legit it worked!!!

i can not set "Content-type: application/json" in header response, my api always return 200 with "content-type: text/html" eventhought i added header in nginx config, please help

I did all of them in order, logged in to the interface, and when I entered the target host in Task Wizard, it gives the error "Failed to find port_list '33d0cd82-57c6-11e1-8ed1-406186ea4fc5'". What is the problem and how can I fix it?

Hi🤚 I want to test that solution today. It will block youtube ad's to ?

Hi - If I don't have the vulnerability detection in the config by default can I add it?

Hey! I am getting below error even all above steps are executed successfully and gvmd service is also up and running.

don't do a sudo su - , use sudo -s instead. If you were to work with applications which require a graphical (like some apects of SAP for exampl) you will run into issues with your environment variables that su - will cobble). The better way is sudo -s or sudo -i -u <user you wish to impersonate> if you need that users actual default env variables. Also, Linux is not Windows; it was built to stay up and running; so, a reboot is not necessary, unless, as you pointed out, there is a new kernel and you need to use that kernel. If you install a new kernel and you don't reboot, it's not a problem. Linux is not Windows; so the bad habits, the fears, insecurities and doubts that windows builds into the minds of its users are not, necessarily, present. Always use a password with your SSH keys; if you want simulate passwordless entry, use ssh-agent and put in your bashrc and then you will only enter your SSH password once via ssh-add and then it will be available during the sessions. If your key is taken, the individual still needs to know the password in order to do anything with it. You will find a bunch of examples on the web of this kind of setup. And it's not Linux 9, but your Distribution and whatever number their release version. Nice video.

Excellent

thank for this video so can you do a tutorial for tuning mysql to support 10000 users RAM 64GB CPU 12 storage 500GB

Thank you very much for this video. I followed step by step on my ubuntu 22.04 VM and it works perfectly.

i have installed openvas on virtual box i am not able to open https: 10.0.2.15/9392 : Problem loading page. Please suggest.

Good

I hate you Nvidia on linux 😂😂😂

Best tutorial! Thanks

What version of ubuntu are you using?

Btw thanks alott…struggle so much fir this but at last found this gem!!!

Is the replication still happens if we restart the sql services after shut down both the isntance ?

Great tutorial. I did it. Thank you so much. However, in my case, there were a few differences. I made the following adjustments: 1. I'm using Red Hat 8, so I had to disable SELinux; 2. I installed MySQL on one machine and cloned it to the second and third machines. Therefore, I had to delete the auto.cnf file located at /var/lib/mysql/ and restart the MySQL service (systemctl restart mysqld.service). => In both cases, errors occurred when running the command: START GROUP_REPLICATION;

I don´t understand why not on faster Debian, why on Ubuntu...

Can you give tutorial for the name

Hi, in the server 2 or server 3 when create Database show this ERROR 1290 (HY000): The MySQL server is running with the --super-read-only option so it cannot execute this statement Server2 After reboot server and Start Replication ERROR 3092 (HY000): The server is not configured properly to be an active member of the group. Please see more details on error log. But when test tutorial all start, but can't create database, only on server1, and don't see in another server. Regards

fine I'll re-write it with dark mode

Thank you for your tutorial, In step, config mysql group replication need to add view to mysql instance sys: ERROR 1305 (42000): FUNCTION sys.gr_applier_queue_length does not exist

OMG THANK U

Thank you so much, this video help me with my problem installing icinga2

Sir how to do NIS so that any user can login from different terminal

thanks for your input, was easy to follow. Only thing to add, if a node is rebooted or mysql is restarted it doesn't auto join unless you add group_replication_start_on_boot = ON

Hello, I was looking at your video channel. We may be helping a company that uses secure images to increase supply chain security and help cloud native development. Would you be willing to help try their software, make a video, and help show devs how to use their tools? This is not an offer, but just to start a conversation about your willingness to take on sponsorship. Please provide me with your email if you are interested. You'd have a chance to look at their technology and decide if it's the type of software that you'd be interested in covering in your channel.

thanks man

thank you a lot for the video, I love using open source tools. Bring more video about open source technologies, please.

The icinga documentation is awful, I spent a lot of time testing with no success, now, following your instructions with small modifications I was able to add a host agent.Thank!

Thank you for crisp and clear explanation......
