# vim /etc/selinux/config
# this file controls the state of selinux on the system.
# 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=permissive

Cobbler裝機平台

和pxe相似，cobbler也是一種批量裝機的手段。cobbler可以自動配置dhcp，dns，tftp，web。可以安裝多種作業系統 pxe需要為每一種作業系統做一種配置 使用cobbler，只需要做一次配置，想要更換系統只需要提供光碟就可以了。1.安裝軟體 yum y install dhcp ...
