@hassan-ki5 

This looks a typical CM database connection issue  can you check and compare the entries in  

cat /etc/cloudera-scm-server/db.properties
com.cloudera.cmf.db.type=[Oracle/mysql/postgresql]
com.cloudera.cmf.db.host=localhost
com.cloudera.cmf.db.name=scm
com.cloudera.cmf.db.user=scm
com.cloudera.cmf.db.setupType=EXTERNAL
com.cloudera.cmf.db.password=scm

Ensure the DB.password, name, and user are correct since you seem to be running Mysql  can you check this page CM using Mysql
