newAdding missing system DB Users to all databases
If, for whatever reason, the system account is missing from MySQL, re-adding it and granting to all DBs manually can be tricky.
This feature allows root to run one command which checks the databases of all User accounts, or one User, to check all DBs and re-add the system accounts as needed.
cd /usr/local/directadmin echo "action=rewrite&value=database_system_users" >> data/task.queue; ./dataskq d306
One specific User:
echo "action=rewrite&value=database_system_users&user=fred" >> data/task.queue; ./dataskq d306
improvedDrop directadmin suid bit support
Starting this version directadmin will no longer support having suid bit set. On update suid bit will be dropped and directadmin will always run under user it was started.
This feature essentially removes functionality based around
/root/.suid_directadmin introduced hereopen in new window
Backwards compatibility for cli call
directadmin --DocumentRoot were added.
improvedBrute force performance improvements
Brute force counters feature was upgraded from file based counters to in-memory based request counters. This should reduce the I/O on busy servers where brute-force protection is turned on.
improvedCloudLinux: update DocumentRoot.cache.json after each httpd.conf write
Relating to the existing DocumentRoot.cache.json cache documented hereopen in new window
which was meant for the now deprecated suid call:
This change will keep the
DocumentRoot.cache.json file updated via
task.queue updates after each write to the User's
The file lives at:
and now has the User's group 640 set, eg:
-rw-r----- 1 diradmin fred 817 Sep 16 16:00 DocumentRoot.cache.json
so the need for the suid binary is no longer needed, as the json file can be read directly.
2 new task.queue calls are used by this feature, can be triggered manually if needed:
echo "action=cache&value=document_root" >> /usr/local/directadmin/data/task.queue echo "action=cache&value=document_root&user=fred" >> /usr/local/directadmin/data/task.queue
Where the user option rewrites the
DocumentRoot.cache.json for just that User. Absense of the user option rewrite the
DocumentRoot.cache.json files for all DA Users.
This task.queue write will trigger if
You can accomplish the same thing by creating:
#!/bin/sh echo "action=cache&value=document_root&user=$username" >> /usr/local/directadmin/data/task.queue exit 0
and set the script to
improvedAPI call for listing all subdomain document roots for all users
CMD_API_DOMAIN command was extended to have a new action
document_root_all to list all web-server document root for all users.
An API call to
.../CMD_API_DOMAIN?json=yes&action=document_root_all would return the same data as a CLI command
directadmin --DocumentRoot executed by root account would do.
This new action is available for admin accounts only.
All integrations relying on
directadmin --DocumentRoot is encouraged to switch to using the new API call. CLI argument will be deprecated and removed in the future.
fixedCGroup: restore User: sets default to Reseller if user.conf blank
If a local Reseller with imposed CGroup limits is trying to restore a User from a remote box which does not have any limits set, the restore might throw an error similar to: Cannot create user fred: cgroup error: CPUQuota is missing
For manual/API User creation, this behavior will be unchanged (to remind the Reseller to set a limit). However for a Restore, a workaround has been added to simply set the Reseller's default value for those limits to allow the User to be restored. The limits can be reduced later, as needed.
fixedshow_all_users_cache_extra_vars: not showing on Reseller List Users
Any of the extra variables from the
CMD_USER_SHOW, if not using the cache would result in a blank field:
this is because it was taken from the cache file, whose container was not filled in this mode.
fixedPhpMyAdmin: one-click SSO can be slow with large information_schema
When a User uses the one-click single-signon to phpMyAdmin, it creates the internal
da_sso_* account name for login. The "username" does not have privileges on views, etc, if the definer is that
da_sso_* username. There is a cleanup task which hunts for the
da_sso_* definers and swaps as needed, documented hereopen in new window
On larger systems where the
information_schema.* is large (specifically
.views in the report), the query to obtain this list can be quite slow.
Fix: Upon the SSO click, instead of doing the cleanup in realtime, push the cleanup request to the task.queue for cleanup ~1 minute later. The cleanup would remove old da_sso accounts, and swap any incorrect definers. As this new da_sso account likely has not yet created any views, this is not critical to run right away.
There is also a call anyway with the nightly tally, but this will ensure that the definers are swapped over more quickly to avoid confusion.
fixedCustom Hook for CMD_API_EXEC: api_exec_pre.sh
Custom hook for
Needed because the
all_pre.sh $command is filled with
/CMD_API_EXEC, but the POSTed command= value contains the binary call. Thus the
all_pre.sh has no way of knowing what the POSTed command is, as it's always filled with
fixedUpdate to set data/lang permissions to diradmin
The gettext .po files might be chowned to root. DA needs to convert them to .mo files via
/usr/bin/msgfmt (from the gettext package), but runs as diradmin. The update will reset
/usr/local/directadmin/data/lang and everything below it to diradmin.
All dirs to 755, files 644.
