#?SELINUX=?can?take?one?of?these?three?values:
#?????enforcing?-?SELinux?security?policy?is?enforced.
#?????permissive?-?SELinux?prints?warnings?instead?of?enforcing.
#?????disabled?-?No?SELinux?policy?is?loaded.
SELINUX=enforcing?????????修改为"SELINUX=disabled"
#?SELINUXTYPE=?can?take?one?of?three?values:
#?????targeted?-?Targeted?processes?are?protected,
#?????minimum?-?Modification?of?targeted?policy.?Only?selected?processes?are?protected.
