最近,我一直试图让Apache服务器监听除默认端口之外的其他端口,即80。一旦我做了必要的配置并通过防火墙允许自定义端口,apache服务器仍然拒绝监听自定义端口。经过一段谷歌搜索,我发现SELinux不允许端口,所以我运行以下命令使Apache服务器监听不同的端口。

semanage port -a -t ftp_port_t -p tcp 8090

在这里,8090是我希望Apache服务器监听的端口。

但它引发了以下错误:

-bash: semanage: command not found

我不知道哪个包会提供'semanage'命令。

因此,让我们输入以下命令来确定哪个包将提供此命令。

yum provides /usr/sbin/semanage

输出:

或者,

yum whatprovides /usr/sbin/semanage

输出:

正如您在上面的输出中看到的,我们需要安装包  policycoreutils-python-2.2.5-11.el7_0.1.x86_64 才能使用'semanage'命令。

yum install policycoreutils-python
