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_tls /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_t3.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
