LE contacts the server by hostname and not by IP. This means that
when installing and reconfiguring the app it hits the default_server
route since nginx configs for the app are not generated at.
When doing in the daily cert renew, the nginx configs exist and we
are unable to renew the certs.
MySQL restarts randomly fail on our CI systems. This is easily
reproducible:
root@smartserver:~# cp /tmp/mysql.cnf . && systemctl restart mysql && echo "Yes"
Yes
root@smartserver:~# cp /tmp/mysql.cnf . && systemctl restart mysql && echo "Yes"
Yes
root@smartserver:~# cp /tmp/mysql.cnf . && systemctl restart mysql && echo "Yes"
Job for mysql.service failed. See "systemctl status mysql.service" and "journalctl -xe" for details.
There also seems some apparmor issue:
[ 7389.111704] audit: type=1400 audit(1509404778.110:829): apparmor="DENIED" operation="open" profile="/usr/sbin/mysqld" name="/sys/devices/system/node/" pid=15618 comm="mysqld" requested_mask="r" denied_mask="r" fsuid=112 ouid=0
The apparmor issue is reported in https://bugs.launchpad.net/ubuntu/+source/mysql-5.7/+bug/1610765,
https://bugs.launchpad.net/ubuntu/+source/mysql-5.7/+bug/1658233 and
https://bugs.launchpad.net/ubuntu/+source/apparmor/+bug/1658239
The e2e is failing sporadically with:
==> Changing ownership
==> Adding automated configs
mysql: [Warning] Using a password on the command line interface can be insecure.
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
Maybe the dhparam creation is doing something causing mysql to not respond.
This is required for various small reasons:
* dir iteration with a way to pass messagein back to the upload() easily
* can be killed independently of box code
* allows us to run sync (blocking) commands in the upload logic
On some provider (https://www.nine.ch) disabling IPv6 makes unbound
not respond to the DNS queries.
Also, I was unable to test with prefer-ip6 to 'no' because unbound fails:
unbound[5657]: /etc/unbound/unbound.conf.d/cloudron-network.conf:8: error: unknown keyword 'no'
unbound[5657]: read /etc/unbound/unbound.conf failed: 3 errors in configuration file
