NodeRED常用操作

記錄使用在雲服務器操作NodeRED過程中常用的一些過程或方法

重啟NodeRED

通過命令行重啟

我的NodeRED在pm2的自啟動管理下,因此使用pm2進行重啟

pm2 restart all 

通過面板重啟

另外一種方法就是通過控制面板直接重啟

可導入以下節點之后點擊即可重啟

[{"id":"8497fd50.d66e1","type":"exec","z":"4487e413.bb781c","command":"sudo ","addpay":true,"append":"","useSpawn":"false","timer":"","oldrc":false,"name":"System Command","x":720,"y":370,"wires":[[],[],[]]},{"id":"c8687228.7cd88","type":"inject","z":"4487e413.bb781c","name":"Restart node-RED","topic":"","payload":"node-red-restart","payloadType":"str","repeat":"","crontab":"","once":false,"onceDelay":0.1,"x":480,"y":370,"wires":[["8497fd50.d66e1"]]}]

修改面板登錄用戶名密碼

1 安裝node-red-admin工具

npm install -g node-red-admin

2 使用工具生成密碼

node-red-admin hash-pw

3 輸入你要的密碼得到加密字符串

4 將字符串替換到/root/.node-red/settings.js文件指定位置中,如下

    adminAuth: {
        type: "credentials",
        users: [{
            username: "dapenson",//改變登錄用戶名
            password: "$2b$08$Kfsos6Pmkrzv6Jx3vfk4xxxxxHxOrU/CY6FIH6XhM5mqFblVmK.",//將生成的密碼填入此
            permissions: "*"
        }]
    },

設置NodeRED自啟動

npm install pm2 -gd

pm2 start node-red

pm2 ls

sudo pm2 startup

sudo pm2 save

當你不需要使其自啟動時,使用以下命令從pm2中刪除該進程

pm2 delete nodered
