首先

使用软件集合（SCL）在CentOS 7中安装Nginx 1.16
原文：Nginx的各种安装方法和EOL综述
参考：快速入门-软件集合

支持

如果使用这种方法进行引入，根据Red Hat软件集产品生命周期 – Red Hat客户门户网站，2021年12月被认为是终止支持日期。之后可能不会进行对报告的漏洞和问题的解决。

# yum install -y centos-release-scl

安装

由于CentOS7.7启动失败，我使用了7.6版本。
Systemd错误：“拒绝接受通过不安全的符号链接链获得的服务控制组之外的进程ID” – 可能受到Red Hat客户门户的影响，但尚未调查。

# cat /etc/redhat-release
