我花了很长时间才让 Ubuntu 22.04、Nginx 和 Certbot 顺利协同运行。
我是 Ubuntu 的新手,所以我正在通过反复试验来学习,不过目前我似乎已经掌握了很多后者的方法。
在公共虚拟机上全新安装。我已经安装了所有三个应用程序。我的网站指向我的域名并且正常运行,但是当我添加 Certbox 时,所有 $#@& 都失效了。现在我根本无法访问我的网站,无论有没有 https。
好的,我将使用“notmydomain.com”作为示例。
我安装了 Certbot 并按照其网站上的说明尝试启动 Nginx。
systemctl start nginx.service
我收到此消息:
Job for nginx.service failed because the control process exited with error code.
See "systemctl status nginx.service" and "journalctl -xeu nginx.service" for details.
所以,我这样做了,并得到了以下结果:
# systemctl status nginx.service
× nginx.service - A high performance web server and a reverse proxy server

我检查了 pem 文件所在的目录:
# ls -l

lrwxrwxrwx 1 root root 44 Oct 28 03:00 cert.pem -> ../../archive/notmydomain.com/cert1.pem
lrwxrwxrwx 1 root root 45 Oct 28 03:00 chain.pem -> ../../archive/notmydomain.com/chain1.pem

-rw-r--r-- 1 root root 692 Oct 28 03:00 README
我注意到所有这些文件都归 root 所有。那么是否应该由其他用户拥有这些文件,以便 Nginx 可以访问它们?这是我的问题吗?谁应该拥有这些文件,以便可以访问它们?
我检查了防火墙权限以确保我没有把自己封锁起来:
# ufw status numbered
Status: active
To Action From

[ 1] Anywhere ALLOW IN xxx.xxx.xxx.xxx
[ 2] 443/tcp ALLOW IN Anywhere
[ 3] 80/tcp ALLOW IN Anywhere

[ 7] 80/tcp (v6) ALLOW IN Anywhere (v6)
[ 8] Nginx HTTP (v6) ALLOW IN Anywhere (v6)
[ 9] Nginx HTTPS (v6) ALLOW IN Anywhere (v6)
我已经重新颁发了证书以确保它没有任何问题,执行此命令时没有出现任何错误:
# certbot certonly --standalone --domain notmydomain.com
Saving debug log to /var/log/letsencrypt/letsencrypt.log

This certificate expires on 2024-01-28.
These files will be updated when the certificate renews.

如果需要的话我可以提供更多信息,只是不知道下一步该看哪里。任何指导都将不胜感激!
