从 CLI 更新：

```plaintext
cd /var/discourse
git pull
 ./launcher rebuild app

```

一切正常，但我遇到了 502 Bad Gateway 错误。

**docker ps**

```plaintext
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
6598e9407e29 local_discourse/app "/sbin/boot" 35 minutes ago Up 22 minutes 0.0.0.0:2045->80/tcp app

```

**./launcher logs app**

```plaintext

ok: run: redis: (pid 47) 17s

supervisor pid: 114 unicorn pid: 118

```

**curl localhost:2045**

```

Discourse 运行在 LXC 容器中，我的第二个论坛也在 LXC 容器中，更新后运行正常。这真的很奇怪。  
有什么建议吗？

更新：  
我看到某些 Ruby 进程仍在运行并占用大量 CPU：

```plaintext
/usr/local/bin/ruby /usr/local/bin/bundle exec config/unicorn_launcher -E production -c config/unicorn.conf.rb

```

更新 2：  
通过将 LXC 从非特权容器更改为特权容器解决了问题。
