chkconfig --list # listing system where all services start
chkconfig --list mysqld # lists services provided mysqld case
chkconfig --level 35 mysqld on # set mysqld in level 3 and 5 serve for the power running, -level 35 indicates the operation performed only in level 3 and 5, indicating that the startup oN, oFF means closed
chkconfig mysqld on # mysqld set to oN at each level, "each level" includes 2, 3,4,5 grade
