LangBot 多租户数据库迁移指南
概述
LangBot 从单租户 OSS 架构迁移到多租户 SaaS 架构,需要执行 7 个数据库迁移(0009-0015)。
迁移序列
0009_workspace_tenancy_kernel → 创建 Workspace、成员、邀请表
0010_scope_tenant_resources → 所有业务表添加 workspace_uuid
0011_postgres_tenant_rls → PostgreSQL 行级安全策略
0012_plugin_installation_identity → 插件实例租户绑定
0013_tenant_pgvector → RAG 向量存储隔离
0014_cloud_directory_projection → Cloud 控制平面同步
0015_cloud_core_collaboration → 协作和权限功能
执行步骤
1. 备份(必须)
# SQLite
cp ~/.langbot/data/langbot.db ~/.langbot/data/langbot.db.backup-$(date +%Y%m%d)
# PostgreSQL
pg_dump -U langbot_user -d langbot_db -F c -f langbot_backup_$(date +%Y%m%d).dump
2. 执行迁移
# 停止服务
sudo -S -p '' systemctl stop langbot
# 执行迁移
python -m langbot.pkg.persistence.migration upgrade head
# 验证
python -m langbot.pkg.persistence.migration current
# 预期: 0015_cloud_core_collaboration
# 启动服务
sudo -S -p '' systemctl start langbot
3. OSS 单租户自动迁移
迁移会自动:
- 创建默认 Workspace(名称:"Default Workspace")
- 第一个用户成为 Owner
- 所有现有资源绑定到该 Workspace
4. 验证检查
# 检查 Workspace
python << EOF
from langbot.pkg.persistence import manager
import sqlalchemy as sa
with manager.engine.connect() as conn:
ws = conn.execute(sa.text("SELECT uuid, name FROM workspaces LIMIT 1")).first()
print(f"Workspace: {ws[1]} ({ws[0]})")
# 检查资源绑定
bot_count = conn.execute(sa.text(
f"SELECT COUNT(*) FROM bots WHERE workspace_uuid='{ws[0]}'"
)).scalar()
print(f"Bots: {bot_count}")
EOF
回滚方案
完全回滚(丢失多租户数据)
# 1. 停止服务
sudo -S -p '' systemctl stop langbot
# 2. 恢复备份
cp ~/.langbot/data/langbot.db.backup-YYYYMMDD ~/.langbot/data/langbot.db
# 3. 回退代码
git checkout v4.10.x
pip install -e .
# 4. 启动
sudo -S -p '' systemctl start langbot
降级迁移(保留数据但移除多租户)
# 警告:会移除 Workspace 表但保留资源
python -m langbot.pkg.persistence.migration downgrade 0008_mcp_resource_prefs
常见问题
Q: 迁移后无法登录
# 检查用户 UUID
python << EOF
from langbot.pkg.persistence import manager
import sqlalchemy as sa
with manager.engine.connect() as conn:
users = conn.execute(sa.text("SELECT id, user, uuid, status FROM users")).all()
for u in users:
print(f"{u[1]}: UUID={u[2]}, Status={u[3]}")
EOF
Q: 资源看不见了
检查 Workspace 上下文:
# 前端请求需要带 X-Workspace-ID header
curl -H "Authorization: Bearer $TOKEN" \
-H "X-Workspace-ID: $WORKSPACE_UUID" \
http://localhost:5200/api/v1/platform/bots
Q: 迁移速度慢
# SQLite 优化
sqlite3 ~/.langbot/data/langbot.db << EOF
PRAGMA journal_mode=WAL;
PRAGMA synchronous=NORMAL;
VACUUM;
EOF
性能调优
PostgreSQL 索引
-- 迁移后创建
CREATE INDEX CONCURRENTLY idx_model_providers_workspace
ON model_providers(workspace_uuid);
CREATE INDEX CONCURRENTLY idx_bots_workspace
ON bots(workspace_uuid);
CREATE INDEX CONCURRENTLY idx_pipelines_workspace
ON pipelines(workspace_uuid);
预估时间
- SQLite < 100MB: 2-5 分钟
- SQLite 100MB-1GB: 5-15 分钟
- PostgreSQL: < 5 分钟(取决于数据量)
