记录一下centos 7.3 semanage 使用报错。处理

2019独角兽企业重金招聘Python工程师标准>>>

[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):
  File "/usr/sbin/semanage", line 32, in

  File "/usr/lib64/python2.7/site-packages/sepolicy/__init__.py", line 907, in 
    raise e
ValueError: 读取 //etc/selinux/targeted/policy/policy.31 策略文件失败

使用centos 7.3 修改apachect端口为88时，发现无法重启。

网上查文章说是SELinux对端口限制，需要去配置端口号。使用semanage来对端口号进行管理，但是semanage一直无法使用，执行如上。以下给出方法：

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

[root@LENOVO-LA0X1 conf]# yum -y install policycoreutils-python.x86_64

自此，可以使用了。
