Jenkins备份及回滚方式

PS:备份脚本存放位置（使用时将脚本放置环境服务包下）注意权限问题

在使用前备份脚本和回滚脚本需要根据实际的服务名称进行修改，并创建备份目录

使用SSH Pubishers执行脚本

执行脚本后，备份文件存放位置（以服务名称为文件，服务加时间戳为文件版本）

根据构建时间给予备份文件

回滚jar

备份脚本

复制代码

#!/bin/bash
set -e  # 出错立即退出，避免静默失败

# ========== 备份配置项（根据实际修改） ==========
APP_NAME="admin"          # 应用名称
ONLINE_APP_DIR="/home/work/app/service/xxx/"       # 线上应用包目录
BACKUP_DIR="/home/work/app/backup/xxx/"    # 备份目录
RETENTION_DAYS=0                 # 备份保留天数
AUDIT_LOG="/home/work/soft/logs/backup_audit.log"  # 备份审计日志

# ========== 核心逻辑 ==========
# 1. 生成精确到秒的时间戳
TIMESTAMP=$(date +%Y%m%d%H%M%S)
# 2. 定义文件路径
ONLINE_APP_PATH="${ONLINE_APP_DIR}/${APP_NAME}.jar"
BACKUP_APP_PATH="${BACKUP_DIR}/${APP_NAME}-${TIMESTAMP}.jar"

# 3. 校验线上包是否存在
if [ ! -f "${ONLINE_APP_PATH}" ]; then
    echo "[$(date +'%Y-%m-%d %H:%M:%S')] ERROR: 线上包 ${ONLINE_APP_PATH} 不存在，备份失败！" >> ${AUDIT_LOG}
    echo "ERROR: 线上包不存在，备份失败！"
    exit 1
fi

# 4. 执行备份（-p 保留文件属性：权限、时间、属主）
echo "[$(date +'%Y-%m-%d %H:%M:%S')] INFO: 开始备份 ${ONLINE_APP_PATH} -> ${BACKUP_APP_PATH}" >> ${AUDIT_LOG}
cp -p ${ONLINE_APP_PATH} ${BACKUP_APP_PATH}


# 5. 校验备份是否成功（对比文件大小）
ONLINE_SIZE=$(du -b ${ONLINE_APP_PATH} | awk '{print $1}')
BACKUP_SIZE=$(du -b ${BACKUP_APP_PATH} | awk '{print $1}')
if [ "${ONLINE_SIZE}" != "${BACKUP_SIZE}" ]; then

    rm -f ${BACKUP_APP_PATH}  # 删除损坏的备份包
    exit 1
fi

# 6. 清理过期备份
echo "[$(date +'%Y-%m-%d %H:%M:%S')] INFO: 清理${RETENTION_DAYS}天前的备份..." >> ${AUDIT_LOG}
find ${BACKUP_DIR} -name "${APP_NAME}-*.jar" -mtime +${RETENTION_DAYS} -delete >> ${AUDIT_LOG} 2>&1

# 7. 记录审计日志
echo "[$(date +'%Y-%m-%d %H:%M:%S')] SUCCESS: 备份成功，备份包路径：${BACKUP_APP_PATH}" >> ${AUDIT_LOG}

# 8. 输出成功信息（供Jenkins日志查看）
echo "备份成功！"
echo "备份包路径：${BACKUP_APP_PATH}"
echo "当前备份列表（按时间倒序）："
ls -lh ${BACKUP_DIR}/${APP_NAME}-*.jar | sort -k9r
