Hi all,
As subject, basically, I used contrib/install-autotest-server.sh to
automatically
build a autotest server, because the script needs to create an 'autotest'
account,
I ran contrib/install-autotest-server.sh as root then got the following error:
<snip>

WRT above error message, there are 2 questions, the one is mysql error "(2002,
"Can't connect to local MySQL server
through socket '/var/lib/mysql/mysql.sock' (2)")"; moreover, the mysql error
will results in defunct 'autotest-schedu',
and the other one is "You can access your server on http://10.66.82.148/afe";,
in fact, this link isn't available.

Q1: mysql error
Mysql default don't allow run mysqld as root due to security reason, but the
script need to create an 'autotest' account
with root privilege, if you run mysqld as root, you will see this error
"Security" section of the manual to find out
how to run mysqld as root!
Notes, Need we to allow run mysqld as root?
Q2:
I think we need to improve script contrib/install-autotest-server.sh, if some
critical
errors happened, the programming should exit and raise expected error
information.
Another question is about "server configuration for the KVM test", the
following link
points out we should change "serve_packages_from_autoserv: True" to
"serve_packages_from_autoserv: False"
in global_config.ini, but it seems the script
contrib/install-autotest-server.sh hasn't
do this, if so, when should we change it? after completing git clone? manually
modify it?

I'm sorry to raise many questions in here, but it indeed confuses me now, any
advise or
solution will be welcomed! Thanks in advance.
