記錄一下centos 7.3 semanage 使用報錯。處理

[root@LENOVO-LA0X1 conf]# semanage -h
ERROR: policydb version 31 does not match my version range 15-30
ERROR: Unable to open policy //etc/selinux/targeted/policy/policy.31.
Traceback (most recent call last):

    import sepolicy

使用centos 7.3 修改apachect端口爲88時，發現沒法重啓。

網上查文章說是SELinux對端口限制，須要去配置端口號。使用semanage來對端口號進行管理，可是semanage一直沒法使用，執行如上。如下給出方法：

[root@LENOVO-LA0X1 conf]# yum provides semanage

自此，可使用了。
