From 0604255ba8f9c617b16a827686f69686e65f46d6 Mon Sep 17 00:00:00 2001 From: Developer Date: Tue, 2 Dec 2025 00:13:24 -0800 Subject: [PATCH] =?UTF-8?q?fix(mpc-system):=20=E4=BF=AE=E5=A4=8D=20Postgre?= =?UTF-8?q?SQL=20=E8=AE=A4=E8=AF=81=E9=85=8D=E7=BD=AE=E9=97=AE=E9=A2=98?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 问题原因: - 部署脚本使用 POSTGRES_PASSWORD 环境变量 - Go 代码使用 MPC_DATABASE_PASSWORD 环境变量 (Viper 前缀) - 变量名不匹配导致数据库认证失败 修复内容: - configure_postgres() 改用 MPC_DATABASE_* 环境变量 - 添加 pg_hba.conf 配置，将 peer/scram-sha-256 改为 md5 认证 - 添加 GRANT ALL ON SCHEMA public 权限 - 使用 127.0.0.1 而非 localhost 进行连接 - 新增 reconfigure 命令用于修复现有安装 服务器修复步骤: sudo ./scripts/deploy.sh reconfigure sudo ./scripts/deploy.sh restart 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- backend/mpc-system/scripts/deploy.sh | 75 ++++++++++++++++++++++------ 1 file changed, 59 insertions(+), 16 deletions(-) diff --git a/backend/mpc-system/scripts/deploy.sh b/backend/mpc-system/scripts/deploy.sh index b4407242..b3995d4b 100644 --- a/backend/mpc-system/scripts/deploy.sh +++ b/backend/mpc-system/scripts/deploy.sh @@ -145,23 +145,42 @@ setup_directories() { configure_postgres() { log_info "Configuring PostgreSQL..." - # Load environment variables + # Load environment variables - use MPC_ prefix variables (same as Go code uses) source "$CONFIG_DIR/mpc.env" 2>/dev/null || true - local DB_USER="${POSTGRES_USER:-mpc_user}" - local DB_PASS="${POSTGRES_PASSWORD:-mpc_secret_password}" - local DB_NAME="mpc_system" + local DB_USER="${MPC_DATABASE_USER:-mpc_user}" + local DB_PASS="${MPC_DATABASE_PASSWORD:-your_secure_postgres_password_here}" + local DB_NAME="${MPC_DATABASE_DBNAME:-mpc_system}" + + # Configure pg_hba.conf to allow password authentication for local connections + local PG_HBA="/etc/postgresql/*/main/pg_hba.conf" + for hba_file in $PG_HBA;
