When I attempt to login to the server, I get through the username and password screen just fine (it rejects bad username/password combinations, and accepts the correct one). However, once I enter my username and password, it stalls for a moment with a message that reads Unable to connect to service.
Error log is:

Any idea whats going wrong.
If I choose a new empty data directory, Nexus starts. But I will lose my existing data.
Update
I was able to bring it up. Downloaded a fresh copy of nexus-repository-helm-0.0.12.jar file and nexus is back online.
However I still can't bring it up as a service. I have to execute nexus/bin/nexus start to get it up. No logs in nexus.log as well.

I'm trying to work through the manual installation guide. When I get as far as registering an admin account for the console (euare-accountcreate) or registering services (euserv-register-service) the eucalyptus-cloud service inconsistently crashes with the same JVM memory error. As an example a few times I've been able to register the UFS or create the admin account but when I move on to perform another step in the install it will fail and checking the service status shows that it has crashed. I don't have experience with Java memory errors and could really use some help understanding whats going on and how to investigate this type of error in general:

I get the following error in Redis 2.8:

What is causing this?
Check the line 103 from your Redis configuration file. You should find the logfile configuration in that line. Then, make sure the the user running the redis process/service has the appropriate permissions (read and write/modify) on that file/folder.

Can any one please help?
I have tried uninstalling and installing many a times but received the same error.
Thanks in advance.
Most of the time if the system journal (journalctl) doesn't show what the problem was, the MariaDB error log (located in /var/lib/mysql/localhost.localdomain.err) does. Looking into that file you usually see what the problem is.
Most commonly errors that do not disappear after a reinstallation mean that your data directory (by default /var/lib/mysql/) is corrupted and the database needs to be reinstalled with mysql_install_db. To make sure you do a clean installation, remove all files located in the data directory and then run sudo mysql_install_db --user=mysql.
I solved as follows:
After installing
Run: > mysql_install_db --user=mysql --basedir=/usr --datadir=/var/lib/
Then: > mysql_secure_installation
And then: systemctl start mariadb
with this this, I can resolved.
A quick update for anyone coming here through a Web search.
I had a "failed to start" message following a Debian 9 -> Debian 10 (Buster) in-place server upgrade, and after a bit of digging I found that the following line in /etc/mysql/my.cnf needed updating:
From:
[mysqld]
: (other stuff)
:
innodb_large_prefix
To:
[mysqld]
: (other stuff)
:
innodb_large_prefix = "ON"
The clue was the following lines in /var/log/mysql/error.log
2020-06-06 16:41:24 0 [ERROR] /usr/sbin/mysqld: option '--innodb-large-prefix' requires an argument
2020-06-06 16:41:24 0 [ERROR] Parsing options for plugin 'InnoDB' failed.
Not sure about your case, But u can check if mariadb/mysql client is deleted accidentally,
Since in my case, I had deleted the mariadb client repo from shared file,So reinstalled the client as,
sudo apt-get install libmariadb-dev
Note: But before installing client do one thing, for rails app just change the mysql version in gemfile and try to install as bundle install mysql2, If its mariadb client issue then it will throw error mentioning that need to install mariadb client or mysql2 client as,
sudo apt-get install libmariadb-dev
OR
sudo apt-get install libmysqlclient-dev
Please refer other answers in case its not mariadb client issue 😊 😜
This is the optimal solution for this problem:
netstat -tulpn | grep LISTEN
Now we need to look for mysqld service.
tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN 32029/mysqld
now kill the process in my case it is (32029).
kill 32029
Now use systemctl start mariadb.service
