修復插件報錯
grafana安裝方法https://www.cnblogs.com/hanxing/p/15995121.html 中 docker run -d -p 3000:3000 --name grafana -v /root/grafana-storage:/var/lib/grafana -e "GF_SECURITY_ADMIN_PASSWORD=123.com" grafana/grafana 映射了目錄 /root/grafana-storage
把插件下載到 /root/grafana-storage 再映射配置文件添加插件地址
1、拷貝grafana配置文件到本地並修改添加插件目錄
docker cp grafana:/usr/share/grafana/conf/defaults.ini /root/grafana-storage
ls -l /root/grafana-storage/defaults.ini 修改添加（映射關系 /root/grafana-storage:/var/lib/grafana）
[plugin.piechart]
path = /var/lib/grafana/plugins/grafana-piechart-panel
2、下載解壓插件
cd /root/grafana-storage/plugins
wget https://grafana.com/api/plugins/grafana-piechart-panel/versions/latest/download -O /opt/grafana-piechart-panel.zip
unzip grafana-piechart-panel.zip
3、重新建一個grafana
docker rm -f 1477e9948777 #刪除
docker run -d -p 3000:3000 --name grafana -v /root/grafana-storage:/var/lib/grafana -e "GF_SECURITY_ADMIN_PASSWORD=123.com" grafana/grafana
docker run -d -p 3000:3000 --name grafana -v /root/grafana-storage:/var/lib/grafana -v /usr/share/grafana/conf/defaults.ini:/root/grafana-storage/defaults.ini -e "GF_SECURITY_ADMIN_PASSWORD=123.com" grafana/grafana
刷新grafana頁面
