1. 准备升级至v5.7.0之前的操作

• 升级deepflow-release

# 挂载镜像
mount -o ro xxxx.iso /media/
# 执行升级
yum --disablerepo=* -y install /media/deepflow-release-*.rpm

2. 准备升级至v5.7.3之前的操作

2.1 备份MySQL数据

# 如本机没有 mysql，可使用 mntnct 或 mysql pod 执行
mysqldump -hmysql -uroot -p -P30130 deepflow --hex-blob > /usr/local/deepflow/patch/deepflow.sql
# 重命名原数据目录，防止干扰新数据
mv /var/lib/mysql /var/lib/mysql_$(date +%Y%m%d)_bak

2.2 备份其他数据目录

备份数据前，需先停止 Salt 部署的服务，参考下节《停止 Salt 模式服务》命令

需 OP 根据当前 Salt 部署环境，找到原数据目录，并通过备份迁移，或软连接的方式，挂载到容器化默认路径下

• 源路径查询参考方式: cat /usr/local/deepflow/saltstack/pillar/disk.sls

容器默认路径参考容器化部署文档 - 依赖 - 数据路径

• pcap：/mnt/pcap
• elasticsearch：/mnt/es
• influxdb-data：/mnt/influxdb/data
• influxdb-meta：/mnt/influxdb/meta
• clickhouse-data: /mnt/clickhouse # 如有多个源文件夹，选择 0-tiers 结尾的
• clickhouse : /var/lib/clickhouse.0/ # 如有多个源文件夹，选择 0-tiers 结尾的，且需修改 templates/values.yaml 中 clickhouse 的 path: /var/lib/clickhouse 为正确目录，示例：path: /var/lib/clickhouse.0

注意： 如 clickhouse 或 elasticsearch Pod 启动报错，可能为数据目录权限不对，参考如下修改目录权限

• clickhouse 目录使用 chown -R 101:101 /var/lib/clickhouse.0/
• clickhouse-data 目录使用 chown -R 101:101 /mnt/clickhouse
• elasticsearch 目录使用 chown -R elasticsearch:elasticsearch /mnt/es
