centos7 semanage 离线安装 SELinux

centos7 semanage 离线安装

还是参考一下 换成阿里云的源 之后 ，在线更新不，不要用离线安装
centos7 更新 yum源 为 阿里云 LTS

CentOS7安装时使用"基础服务器"选项安装, 后发现没有semanage命令.

ss -tnlp

可以通过 getenforce 命令查看 SELinux服务的运行状态。# setenforce 0

getenforce

Permissive

使用yum查询选项搜索

1、使用yum查找提供此功能的的软件包：

# yum provides /usr/sbin/semanage
或者

# yum whatprovides /usr/sbin/semanage

[root@localhost ~]# yum provides semanage
按照搜索结果安装对应包即可解决

[root@localhost ~]# yum install -y policycoreutils-python

ping www.baidu.com
不用加 sudo
yum provides semanage  
/usr/sbin/semanage
yum install -y policycoreutils-python-2.5-34.el7.x86_64
semanage 
semanage fcontext -l|grep mysqld_db_t

ls /opt/datadir/mysql/
ls
semanage fcontext -a -t mysqld_db_t "/opt/datadir/mysql(/.*)?"
restorecon -Rv /opt/datadir/mysql
semanage fcontext -l|grep mysqld_db_t

3.修改SELinux

添加修改的端口号到SELinux：semanage port -a -t ssh_port_t -p tcp 22492

并检查是否添加成功：semanage port -l | grep ssh，如图出现修改端口号，即为成功。

通过semanage管理SELinux

不用加 sudo
yum provides semanage
cat /etc/redhat-release
CentOS Linux release 7.6.1810 (Core)
在上面的系统里面运行

[jack@localhost ~]$ yum provides semanage
