首先

使用公式存储库在CentOS7上安装最新版的Nginx主线版本。
原文：Nginx的各种安装方法和EOL总结
参考：nginx：Linux包

支持

如果使用这种方法进行部署，我认为会得到支持，直到停止开发nginx为止。
如果不指定特定版本，我认为将始终提供mainline的最新版本。

自動啟動/取消設定nginx。

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

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

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

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