nginx - 为什么更新 arangoDB 会导致 nginx 错误？

问题描述

我有版本 3.3.5 并想升级到 3.3.11。使用了以下脚本：

#Step 1 Copy the whole data directory of arango to another location, basically a backup

cp -R /var/lib/arangodb3 /folder

#Step 2 Stop the current running process

service arangodb3 stop

#Step 3 Installing new ArangoDB, adding the key and stuff (the below is for 16.04 Ubuntu)

curl -OL https://download.arangodb.com/arangodb33/xUbuntu_16.04/Release.key
sudo apt-key add - < Release.key
sudo apt-get install apt-transport-https

sudo apt-get update
read -p "Enter the version zou want to upgrade to (For example 3.3.5)" version
sudo apt-get install arangodb3=$version

#Step 4 Start the process again with auto-upgrade option on
service arangodb3 start --database.auto-upgrade

在第 3 步结束时。安装 arango 版本时会弹出此错误

一个nginx错误。我的问题是这里的nginx在arango升级中的作用是什么？（似乎arango无法启动它自己的nginx）

解决方案

该问题与nginx无关。您的 arangodb 安装似乎没有正确完成。结果systemctl deamon-reload出错了...请运行

sudo dpkg-reconfigure arangodb3

请用输出更新您的问题。
