How to view processes and kill processes

Sometimes when we execute an SQL statement or change the table structure, due to the huge amount of data in this table, we often get stuck after executing the operation…and then this table will be locked. At this point, we can kill the process.

Then, he still found the corresponding ID:

KILL 42736;kill all slow query processes and lock table processes 1, kill all slow query processes #!/ bin/bashmysql -uroot -pMy_Password -e "show processlist" | grep -i "Query" > slow_query.logfor query in `cat slow_query.log | awk '{print $1}'`do echo "kill $query;" > kill_slow_query.sqldone

Log in to mysql and execute:

mysql> source kill_slow_query.sql

Or:

#!/ bin/bashfor query in `mysqladmin -uroot -pMy_Password processlist | grep -i 'Query' | awk '{print $2}'`do mysqladmin kill ${query}done2, kill all deadlock processes #!/ bin/bashmysql -uroot -pMy_Password -e "show processlist" | grep -i "Locked" > locked.logfor lock in `cat locked.log | awk '{print $1}'`do echo "kill $lock;" > kill_locked.sqldone

Log in to mysql and execute:

mysql> source kill_locked.sql

Or:

#!/ bin/bashfor lock in `mysqladmin -uroot -pMy_Password processlist | grep -i 'Locked' | awk '{print $2}'`do mysqladmin kill ${lock}done Here, I believe everyone has a deeper understanding of "MYSQL how to view the process and kill the process", may wish to actually operate it!
