mongodb install

安裝依照官網：

• install mongodb on ubuntu

一般的動作：

1. 加 pgp key
2. 加sources.list
3. apt update
4. apt install

裝完 default config 會在： /etc/mongod.conf
config 裡面的 ..

• storage: /var/lib/mongodb
• log: /var/log/mongod/mongod.log
• net: 127.0.0.1:27017

apt 會安裝到 systemd : mongod.service

---

結果 在 pi3 上，用 debian 64bit 的 apt 安裝，service run fail。

單純 run docker mongo:

$ docker run -it -p 27017:27017 -v ~/mongoinstall_arm64:/mongoinstall mongo

WARNING: MongoDB 5.0+ requires ARMv8.2-A or higher, and your current system does not appear to implement any of the common features for that!

需要參考mongodb under raspbian64，用另一版的 mnogodb
依照這個網頁說明，放到 mongoinstall_arm64。

需要 curl, libssl-dev

所以也 用 4.4.14 看看

$ docker run -it -p 27017:27017 -v ~/mongoinstall_arm64:/mongoinstall mongo:4.4.14

可以 run 起來。
所以用 docker host 端的 mongo client 來測試...

---

安裝完，除了用 systemctl status 看service 狀態，也可以用 mongodb client console 來測試。
ref:

• getting start with mongodb shell
• MongoDB 連線與 IDE
• MongoDB Shell工具：mongosh的使用
• mongo shell command helers

新的 client 是 monogosh。
連線語法是：

mongosh mongodb://root:rootpasss@mogoserver:27017

---

有關 docker
docker imnage : mongo 的版本是 5.0.3 ，和一般(ubuntu 20.04) distribution 的版本 3.0 不一樣。
舊版本的 client 無法和版本連線。
所以也要用 docker 來連..

docker run -it mongo --interface mogocontainer-network mongosh mongodb://root:rootpassword@mogocontainername:27017

要跟 mogocontainer 同一個 network，才能直接用 container name 來連接。
