问题
I tried to sudo netstat -natp | grep mysql to see what port mysql was listening on and I see that it is actually listening on what is below. I also did an ifconfig to see what ip I was on within the vagrant box. I am trying to find out this info so that I can connect to a mysql database through a vagrant virtual machine, but use that information in an .env inside of a laravel application that is outside of the box. Can anyone help?
tcp 0 0 0.0.0.0:3306 0.0.0.0:* LIST
回答1:
In /etc/my.cnf, make ensure you have the following configuration:
1) Comment out this line if it's present, as it prevents external access
#skip-networking
2) Set bind-address to as follows, if set to locahost, only local connections will be possible:
bind-address=0.0.0.0
3) Restart MySQL with:
sudo service mysql restart
This should do it.
If it doesn't then you may have a firewall consideration to take care of. If you're on the default iptables, then run:
iptables -A INPUT -p tcp -m tcp --dport 3306 -j ACCEPT
To verify the port is open, from your external host (not the VM) you can run:
nmap <vm-ip-address-here>
If you don't see 3306 open, you have other uncommon networking issues.
