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.
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
logrotate config files may contain arbitrary commands which are
exectued as root, thus the config files have to be owned by root.
This is the reason we need the sudo scripts :-/
To test the generated scripts, just run:
$ logrotate /etc/logrotate.conf -v
Fixes#396
The built-in df plugin cannot do the following:
* if we choose by type ext4, we want to skip devicemapper (on scaleway)
* the MountPoint of the appsdata directory is not possible to know at install time
Fixes#398
