2019獨(dú)角獸企業(yè)重金招聘Python工程師標(biāo)準(zhǔn)>>>

在安裝Cobbler和Puppet時(shí)需要關(guān)閉selinux，但是通常情況下載安裝完CentOS7后，默認(rèn)情況下SElinux是啟用狀態(tài)，

如下所示：

[csharp]?view plaincopy

?

[root@rdo?~]#?sestatus??

SELinux?status:?????????????????enabled??

SELinuxfs?mount:????????????????/sys/fs/selinux??

SELinux?root?directory:?????????/etc/selinux??

Loaded?policy?name:?????????????targeted??

Current?mode:???????????????????enforcing??

Mode?from?config?file:??????????enforcing??

Policy?MLS?status:??????????????enabled??

Policy?deny_unknown?status:?????allowed??

Max?kernel?policy?version:??????28 ?

1、如果要臨時(shí)關(guān)閉，可以執(zhí)行

[cpp]?view plaincopy

?

setenforce?0??

此時(shí)的狀態(tài)如下

[html]?view plaincopy

?

[root@rdo?~]#?sestatus??

SELinux?status:?????????????????enabled??

SELinuxfs?mount:????????????????/sys/fs/selinux??

SELinux?root?directory:?????????/etc/selinux??

Loaded?policy?name:?????????????targeted??

Current?mode:???????????????????permissive??

Mode?from?config?file:??????????enforcing??

Policy?MLS?status:??????????????enabled??

Policy?deny_unknown?status:?????allowed??

Max?kernel?policy?version:??????28 ?

2、如果要永久關(guān)閉，可以修改配置文件/etc/selinux/config，將SELINU置為disabled。

[html]?view plaincopy

?

[root@rdo?~]#?cat?/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=enforcing??

SELINUX=disabled??

#?SELINUXTYPE=?can?take?one?of?three?two?values:??

#?????targeted?-?Targeted?processes?are?protected,??

#?????minimum?-?Modification?of?targeted?policy.?Only?selected?processes?are?protected.???

#?????mls?-?Multi?Level?Security?protection.??

SELINUXTYPE=targeted???

修改該配置文件也可以執(zhí)行下面的命令來(lái)完成

[html]?view plaincopy

?

sed?-i?'/SELINUX/s/enforcing/disabled/'?/etc/selinux/config ?

修改完成后，保存重啟，重啟后狀態(tài)如下：

[html]?view plaincopy

?

[root@rdo?~]#?sestatus??

SELinux?status:?????????????????disabled??

?
