首先

使用软件集合（SCL）在CentOS7上安装Nginx1.18。
原文：Nginx的各种安装方法和结束生命周期(EOL)总结
参考：快速入门 — 软件集合

支援

如果以本方法引入的话，根据Red Hat软件集产品生命周期 – Red Hat客户门户网站的信息，2022年11月可能会被认为是终止支持（EOL）的时间。
在此之后，可能不会进行对报告的漏洞和问题的响应。

# yum install -y centos-release-scl

安裝

与 1.16 版本相同，由于 CentOS 7.9 无法启动，因此我们使用了 7.6 版本。
Systemd 错误：’拒绝接受服务控制组外的 PID，通过不安全的符号链接链获得’ – Red Hat 客户门户可能受其影响，但尚未进行调查。

# systemctl enable rh-nginx118-nginx
Created symlink from /etc/systemd/system/multi-user.target.wants/rh-nginx118-nginx.service to /usr/lib/systemd/system/rh-nginx118-nginx.service.

# systemctl list-unit-files --type=service |grep nginx
rh-nginx118-nginx.service              enabled

# systemctl disable rh-nginx118-nginx
