我想在Amazon Linux 2中使用主管程序包管理器运行ASP.Net Core应用程序。执行以下命令以安装主管程序
$ sudo yum安装主管
它说：
Loaded plugins: extras_suggestions, langpacks, priorities, update-motd
No package supervisor available.
Error: Nothing to do
Os详细信息：
NAME="Amazon Linux"
VERSION="2"
ID="amzn"
ID_LIKE="centos rhel fedora"
VERSION_ID="2"
PRETTY_NAME="Amazon Linux 2"
ANSI_COLOR="0;33"
CPE_NAME="cpe:2.3:o:amazon:amazon_linux:2"
HOME_URL="https://amazonlinux.com/"
也尝试过
$sudo yum install epel-release
相同错误：
Loaded plugins: extras_suggestions, langpacks, priorities, update-motd
No package epel-release available.
Error: Nothing to do

epel-release在Amazon Linux Extra主题“ epel”中可用
$sudo amazon-linux-extras install epel
然后我尝试了
$sudo yum install supervisor
输出！
Loaded plugins: extras_suggestions, langpacks, priorities, update-motd
150 packages excluded due to repository priority protections

标准存储库可能未提供可以在CentOS，Red Hat Enterprise Linux（RHEL）或基于Amazon Linux的发行版上安装的所有软件包。
在RHEL 7和Amazon Linux 2上安装并启用EPEL rpm软件包
sudo yum install -y https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
在RHEL 6上安装并启用EPEL rpm软件包
sudo yum install -y https://dl.fedoraproject.org/pub/epel/epel-release-latest-6.noarch.rpm
现在您可以运行：
sudo yum install supervisor
