I upgraded my os x to Sierra and reinstalled my brew list, everthing went well till I reinstalled mariadb.
The database is not starting, i get .ERROR! on mysql.server start
I checked the logs, but i only have two warnings :
2016-10-09 10:56:17 140735690990528 [Warning] Setting lower_case_table_names=2 because file system for /usr/local/var/mysql/ is case insensitive
2016-10-09 10:56:17 140735690990528 [Note] Plugin 'FEEDBACK' is disabled.
I'm pretty sure this is not the problem.
Update :
I figured out why the server couldn't start, i had put the service to auto start putting it in ~/Library/LaunchAgents so when i started it i had a log saying:
mysqld is already running
So i removed the service from the launchAgents but now when I try to start it, i just get :
Starting MySQL
...............................................
with infinite dots
Update && RESOLVED :
I finally found the solution, the problem here was the mysqladmin not pinging because of a problem in my.cnf so the server started but mysqladmin couldn't ping the server to prompt SUCCESS.
Also my first problem seemed to be a problem in the log-error, i had much logs with different names, i deleted them all and my server works fine now

I want to set up rstudio-server on an iMac with support for multiple users and remote login. I followed the steps in the INSTALL tutorial: I built the source, set up the configuration files and the launchd daemon. At first, it works fine, but after some time, I get these warnings/errors when I plot:
2022-06-09 08:02:29.438 rsession[3050:139329] XType: failed to connect - Error Domain=NSCocoaErrorDomain Code=4099 "The connection to service named com.apple.fonts was invalidated: failed at lookup with error 3 - No such process." UserInfo={NSDebugDescription=The connection to service named com.apple.fonts was invalidated: failed at lookup with error 3 - No such process.}
2022-06-09 08:02:29.438 rsession[3050:139329] Font server protocol version mismatch (expected:5 got:0), falling back to local fonts
2022-06-09 08:02:29.438 rsession[3050:139329] XType: unable to make a connection to the font daemon!
2022-06-09 08:02:29.438 rsession[3050:139329] XType: XTFontStaticRegistry is enabled as fontd is not available.
Then I can't plot any more unless I restart R and re-run my code. Do you know what could be the issue? I could not get any help when opening an issue on the rstudio-server github since MacOS is not officially supported.
I was also looking at running rstudio-server via docker, but I couldn't find a good way to map the user namespace from macOS to the container.
Any help or suggestion would be greatly appreciated!
EDIT: It seems I was able to solve the issue by launching the fontd daemon with:
sudo launchctl load -w /System/Library/LaunchAgents/com.apple.fontd.useragent.plist
This seems like an issue with the MacOS font daemon, not with RStudio itself.
Someone reported a similar issue on PhantomJS. Rebooting resolved it for them.
This answer reported the same error for a different build, and they were able to resolve it by installing the correct "Apple Worldwide Developer Relations Certification Authority" in Keychain:
The one I had had an expiration date of February 2023. I deleted that one and went here, downloaded the one called "Worldwide Developer Relations - G3 (Expiring 02/20/2030 00:00:00 UTC)", then retried the build and it worked.
I am trying to run jupyterhub on an Ubuntu 20.04 LTS server. My idea is to run python/jupyterhub in a conda virtual environment as a system service. As I want to be able to limit the resources available to individual users I installed the systemdspawner.
After installing everything and starting the jupyterhub service I can login through my web browser. However, when trying to start the server the spawner stucks and after a while I get an error message saying "Spawn failed: Timeout"
in journalctl I can see the following messages:
User logged in: me 302 POST /hub/login?next= -> /hub/spawn (me#::ffff:[my IP address]) 59.42ms

Disclaimer: My Jupyter/Python installation is replacing an former installation that was setup by someone else and got messed up a bit during time. I tried to remove everything related and start with a clean installation from scratch. However, as I had very little documentation about the old setup there is a certain risk that there might be some left-overs of the previous installation that may cause trouble.
Any ideas?
Solved it out myself. In the end the PAM related messages seem to be non-critical and were not related to the timeout at all. Instead I found a mistake in /etc/systemd/system/jupyterhub.service, where the PATH variable was not including the bin directory of my miniconda installation.
I spent a lot of time trying to debug and fix a database that was working without a problem few days earlier, and is refusing to start with:
FATAL ERROR: Upgrade failed
after adding the env var:
- name: BITNAMI_DEBUG
value: "true"
I can see that the real error is:
2021-07-14 23:12:32 0 [ERROR] Fatal error: Can't open and lock privilege tables: Table 'mysql.db' doesn't exist
2021-07-14 23:12:32 0 [ERROR] Aborting
crazy that bitnami hides these errors by default....
Until now I couldn't figure out what broke it and how to really fix it, but I managed to start the database by exec into the container and running:
adduser mysql --uid=1001
chown mysql:root /opt/bitnami/mariadb/tmp/
mysql_install_db --user=mysql --basedir=/opt/bitnami/mariadb --datadir=/bitnami/mariadb/data
mysqld --skip-grant-tables --user=mysql --skip-external-locking --port=3306 --sock=/opt/bitnami/mariadb/tmp/mysql.sock --datadir=/bitnami/mariadb/data
After running the db I managed to run a mysqldump, copy all what is relevant for me, and reinstall a new db from scratch then restoring the content.
Why the user was not present and why I needed to change the permissions is beside me.
I am glad you were able to recover the database. I was going to suggest the mysql_install_db command as you mentioned, I am not sure if there is any other approach to solve that kind of issue. In any case, I think the ideal solution would pass through finding what causes the problem initially.
I have installed Couchbase 2.2.0 for Windows 7 64 bits. I installed it using the default options. The service gets installed and I can stop/start or restart it without errors. However, I cannot connect to the management console on port 8091.
I've found some posts on how to deal with this but they all relate to older versions of couchbase and reference files/options I can't find in version 2.2 (for example this post : Unable to connect to http://localhost:8091/index.html).
When I try netstat -an -p tcp I can't see any service listening on port 8091 so I suspect something goes wrong during startup.
Looking in the couchbase log in /var/lib/couchbase/logs I can see some errors but they don't make sense to me.

The windows firewall is running but, since I installed the same version of couchbase on another machine with the same Windows version without troubles I can't imagine that the firewall is causing this trouble.
I'm out of options though, I have no idea why I can't get this to work.
In the meantime, I have uninstalled 2.2 and tried falling back to 2.1 (with the same result) and moving forward to 2.5 (with the same result). In all cases I turned of antivirus software and stopped the Windows firewall to eliminate this cause.
Thanks to the nice people at Couchbase.com, the problem has been solved.
Please refer to :
https://www.couchbase.com/issues/browse/MB-10245
https://www.couchbase.com/issues/browse/MB-8760
The solution is to reinstall couchbase in a location without spaces in the path. Due to a bug, spaces in the installation path lead to trouble.
I'm trying to create a database using DBCA on Oracle 11g installation on Ubuntu Linux 12.04 64 bit.
I followed the instructions here, but I get
ORA-12547: TNS Lost Contact when running DBCA.
Below are the details. Can someone assist with the solution?
Instead of using /opt/oracle as the "oracle" user home, I used /home/oracle
I did not install the libstdc++5 in 32 bit version
I did everything else the same as the posting
Installation resulted in "missing packages". I tried to do an apt-get install for these packages from ubuntu, but ubuntu says that they don't exist.
Then I saw in the instructions:
Once you will reach the "pre-reqs" screen, check "Ignore all" to continue the installation.
When running ./dbca from $ORACLE_HOME/bin, it fails with ORA-12547.
I checked $ORACLE_HOME/network/admin and listener.ora , sqlnet.ora , and tnsnames.ora all look OK.
However, I think that tnsnames.ora is not being read properly, because ./tnsping fails and the error message states that "EZ Connect" was used.
But in my sqlnet.ora , I have
names.directory_lookup = (TNSNAMES,EZCONNECT)
It should use EZ Connect only after tnsnames is tried.
Also, I sometimes get ORA-12541: No listener. I tried running ./netca. Everything is OK until I perform a test on the listener, and it fails.
I can't run ./lsnrctl. Absolutely nothing happens for this, as well as lsnrctl start, stop, status.
I can't go through sqlplus. If I run ./sqlplus , it asks me for username/password directly.
If I do ./sqlplus / as sysdba, then this results in "ORA-12547: TNS lost contact".
All environment variables are set correctly in .bashrc.
I tried re-running root.sh , but the problem is not fixed.
/etc/oratab is OK
/etc/hosts is OK, but I can't always ping the "localhost" or "127.0.0.1", or "ubuntu" or "127.0.1.1"
The same TNS or Listener errors display.
When I login in oracle (sqlplus system/pass as sysdba), I got this:
ERROR:
ORA-12547: TNS :lost contact when try to connect to Oracle.
First, I think the server is down, but I check it, it is OK. And so many body say 'chmod 6751 oracle', I did it, but I got another error:
ERROR:
ORA-01031: insufficient privileges
Enter user-name:
finally, I switch the system user from root to oracle. And I login success.
Ensure the DB is up and running and you can connect locally AS SYSDBA to the database
using Oracle binaries owner (usually oracle:oinstall Unix / Linux user). If it does not
work, probably you encounter a different problem.
1. Check privileges of an Oracle file on Unix / Linux host where database is running:
cd $ORACLE_HOME/bin
ls -ltr oracle
2. Change permissions as below:
chmod 6751 oracle
ls -ltr oracle
This code may help you lot.
