备份及卸载节点¶

备份¶

其实备份之前章节提过一次,就是备份 .node-red目录里面文件, 如何找到这个文件参考上一章节.
node_modules 这个目录是不需要备份的,它是节点依赖的第三方模块,可以通过到新的机器上执行下面命令进行安装:

npm install

群晖配置文件夹查找¶

这里主要说明一下没有手动添加映射的情况,需要使用 ssh 登录群晖控制台然后 sudo -i 进入root用户,进入Docker 安装的数据卷中,如下图:

node_red_config_2

cd /volume1/@docker/btrfs/subvolumes/
# 查看所有文件
ls -all
#

带有xxx-init这样标识的就是Docker的数据卷, 暂时没有方法直接知晓容器对应的,用以下命令查找:

find ./ -name settings.js
#输出信息如下:我这里启动了两个Node Red

./f06a95eccfbcf414e5640008fe2d3cb0bf6fed88b421b44d0fa0e7bfbd00c6af/data/settings.js

然后 cd f06a95eccfbcf414e5640008fe2d3cb0bf6fed88b421b44d0fa0e7bfbd00c6af/data 就是Node Red 相关文件了

卸载节点¶

多数情况下直接在界面上操作即可,但是有时候会有点不灵光,这时候就需要手动进行操作了,运行下面命令:

第一步
删除所有依赖模块 rm -rf node_modules
第二步
打开package.json 删除对应节点信息
第三步
执行npm install 安装依赖
第四步
重启Node Red

vi package.json
