Hey Michael,

How did you deploy Scalr?

Hey Michael,

Would you mind trying restarting memcached? I was able to reproduce your issue, but it seems very elusive (and went away when I restarted memcached..).

Let me know how that pans out for you. If that doesn't work I'll have a few next steps for you to debug this. 

Thanks!

Hi Thomas,

  First thank you for your reply. I downloaded scalr-server-5.1.0.oss~nightly.20150216043620.184.7f0df7f.d4e1f1f~el.6-1.x86_64.rpm and install it on a centos 6.5 vm.
  I tried to restart memcached & httpd with scalr-server-manage. but unfortunately it is not work for me. do you have any suggestion?

Thanks,
-Michael

Hey there,

We've had some issues with SASL authentication on memcached failing. Unfortunately, Memcached's SASL library isn't super helpful when it comes to logging.

Let's see if this your problem.. 

Please follow the following steps:
- Make sure memcached is running (and that it's the only memcached instance running)
- Install gdb: yum install gdb
- Prepare gdb to run memcached: gdb -p $(pidof memcached)
- Setup a breakpoint to log all calls to the sasl_seterror function by typing the following in the gdb prompt

b sasl_seterror
commands 1
silent
bt 1
c
end
c

Then, try to login one more time. Paste the output you get here (just make sure there is no password in there).

Cheers,

So, looks like a password issue. Can you run the three following commands for me?

/opt/scalr-server/embedded/sbin/sasldblistusers2 
/opt/scalr-server/embedded/sbin/sasldblistusers2 -f /opt/scalr-server/embedded/etc/sasldb2
ls -lah /opt/scalr-server/embedded/etc/sasldb2

Hi Thomas,
  
     Following is the output. BTW, I found I can't login to mysql with root & scalr. error info is 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES).

Thanks, everything looks good there. 

Can you try updating to the latest package? It should be scalr-server-5.1.0.oss~nightly.20150216201534.188.7f0df7f.2887cd2~el.6-1.x86_64.rpm

Once done, please run scalr-server-ctl reconfigure.

Regarding MySQL: this is probably a red herring. If Scalr wasn't able to connect to MySQL, it wouldn't be able to verify the admin password, and it wouldn't try to connect to Memcached.

Cheers,

Just to confirm: how did you download the package to install it? What was the output of the reconfigure step?

Thanks

Hey Michael

As we discussed off list.. I looked into your issue.

I finally found the problem. It's happening because your hostname has uppercase letters in it, which is causing Memcached and sasldb to get confused, and fail authentication.

I fixed the issue manually on your server for now, but I'll try and find a better solution.

I download the rpm package from aws s3 per wget.
And then using rpm -ivh ******.rpm to install it.
Since my network speed is not good. So I didn't use script.rpm. Just wget scalr rpm package about 242Mb. Install it with rpm -ivh.
