"Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock'"

[danielbachhuber]

My builds are failing on this error:

mysql -e 'CREATE DATABASE wp_cli_test;' -uroot
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

See https://travis-ci.org/wp-cli/wp-cli/jobs/174318358 for a representative job.

This issue is specific to Travis CI and new within the last ~8 hours. Happy to help debug further if you'd like to point me in a direction.

Also seeing this on the Container-based Ubuntu Trusty Public Beta

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

Reference #5695

[danielbachhuber]

Thanks @photodude. Didn't realize infrastructure changes rolled out today.

@danielbachhuber Looks like your running Trusty beta. drop dist: trusty from your travis.yml to fix the issue. @szepeviktor made that change.

[danielbachhuber]

@photodude Right. Can we expect the issue to be fixed any time soon, or should I revert in all of the relevant places?

[photodude]

I would revert for now for live repos needing to do continuous testing since Trusty is beta. Test your repo with trusty beta in a separate repo and plan to migrate some time after Q1-17 when it's officially released.

Trusty likely doesn't benefit you unless you need something like HHVM 3.9+ (current hhvm is 3.15) which is trusty specific.

[danielbachhuber]

👍 Thanks for your help, @photodude

[photodude]

You are welcome @danielbachhuber, Glad your up and testing again. Hopefully the trusty issues can be sorted out soon (I'm hoping it will be faster for testing HHVM)

PS Please keep this issue open until it's resolved on Container-based Trusty Beta.

I symlinked the socket and it works provided you have sudo required in your .travis.yml

sudo mkdir -p /var/run/mysqld
sudo ln -s /run/mysql-5.6/mysqld.sock /var/run/mysqld/mysqld.sock

@lesterchan symlinking the socket like that doesn't work on the Container-based Trusty Beta as sudo is disabled on the Containers.
