What does semanage port -l | grep 1186 show afterward?
# semanage port -l | grep 1186
mysqld_port_t tcp 1186, 3306
What do you mean by "didn't work", i.e. same avc
message repeated
afterward upon subsequent attempts to connect?
type=AVC msg=audit(1197324654.830:1482): avc: denied {
name_connect } for pid=20484 comm="mysqld" dest=54859

The command should cause the port to be treated with that type for
all
subsequent permission checks, whether name_connect or name_bind.
