cloud-management dead but pid file exists 7 months, 2 weeks ago #7504

I am not able to access the management console through cloud management URL. I have restarted the cloud-management service but while verify the status it says "cloud-management dead but pid file exists". I cross verify the log file "/var/log/cloud/management/management-server.log" and could see some issues with database. Then I tried to restart the mysql database and found the message "mysql: unrecognized service".

Can somebody help me in resolve the issue ?

following is the tail of the above log file.

I'm guessing that you have your database server and management server run on the same machine. Just to check if youi have mysql installed type:
rpm -qa mysql

If it is not installed I would suggest you to erase previously created databases located in : /var/lib/mysql . Erase everything in that dir. Rerun ./install.sh script in your Cloudstak and choose D for database. Follow the instructions for setting up a database for database server.
when you are finished you should have mysql up and prepared for launch. Also check if your mysql is running : service mysqld status . If it fails to load, check /var/log/mysql.log for errors. Also check if you have this in /etc/my.cnf
innodb_rollback_on_timeout=1
innodb_lock_wait_timeout=600
max_connections=350
log-bin=mysql-bin
binlog-format = 'ROW'


If not, add those lines and rerun mysql.
