首先

使用Application Stream（AppStream）在CentOS8上安装Nginx1.14。
参考：RHEL8的软件包结构-BaseOS和Application Stream-红帽工程师博客。

支持

根据我们使用的方法，根据《Red Hat Enterprise Linux 8 Application Streams Life Cycle – Red Hat Customer Portal》，预计2021年5月将到达终止支持（EOL）。
此后可能不会对报告的漏洞或问题进行修复。

Nginx自动启动及设置取消。

# systemctl enable nginx
Created symlink /etc/systemd/system/multi-user.target.wants/nginx.service → /usr/lib/systemd/system/nginx.service.

# systemctl list-unit-files --type=service |grep nginx
nginx.service                               enabled

# systemctl disable nginx
Removed /etc/systemd/system/multi-user.target.wants/nginx.service.

# systemctl list-unit-files --type=service |grep nginx
nginx.service                               disabled

各种确认 – gè
