echo $KINGBASE_PASSWORD

备份脚本 auto_backup.sh

#!/bin/bash

# 从脚本参数中读取数据库名称
if [ $# -eq 0 ]; then
    echo "Usage: $0 <database>"
    exit 1
fi

database=$1

# 检查数据库名称是否有效
if [ -z "$database" ]; then
    echo "Error: Database name cannot be empty."
    exit 1
fi

# 动态生成备份文件名
timestamp=$(date +"%Y%m%d%H%M%S")
backup_path="/opt/Kingbase/ES/V8/backup"
backup_file="${backup_path}/${database}_$timestamp.sql"
echo "Backup file: $backup_file"

# 检查备份路径是否存在并可写
if [ ! -d "$backup_path" ] || [ ! -w "$backup_path" ]; then
    echo "Error: Backup path does not exist or is not writable."
    exit 1
fi

# 执行备份命令
echo "Executing backup command: /opt/Kingbase/ES/V8/Server/bin/sys_dump -h 127.0.0.1 -p 54321 -U system -f $backup_file $database"

# 使用 && 来确保命令执行成功
/opt/Kingbase/ES/V8/Server/bin/sys_dump -h 127.0.0.1 -p 54321 -U system -f "$backup_file" "$database"
if [ $? -ne 0 ]; then
    echo "Error executing backup command."
    exit 1
