安装ossutil
wget https://gosspublic.alicdn.com/ossutil/1.7.19/ossutil-v1.7.19-linux-amd64.zip
yum -y install unzip
unzip ossutil-v1.7.19-linux-amd64.zip
cd ossutil-v1.7.19-linux-amd64
cp ossutil64 /usr/local/bin/
chmod +x /usr/local/bin/ossutil64
ossutil64 -v
然后在服务器用户主目录下创建一个 .ossutilconfig 文件，文件内容如下：
[Credentials]
language=EN
accessKeyID=AccessKey
accessKeySecret=SecretKey
endpoint=oss-cn-hangzhou.aliyuncs.com
创建定时备份脚本：nginx_conf_backup.sh
#!/bin/bash# 环境
env="uat"# Nginx配置文件路径
nginx_config_path="/etc/nginx"# 备份主目录
backup_main_dir="/data/nginx_conf_backup"# 创建每天的独立备份目录
backup_dir="$backup_main_dir/nginx_backup_$(date +'%Y%m%d')"
mkdir -p $backup_dir# 备份文件名，包含日期
backup_file="nginx_config_$(date +'%Y%m%d')"# 备份nginx.conf
cp "$nginx_config_path/nginx.conf" "$backup_dir/nginx.conf"# 备份conf.d目录下的所有文件
cp -r "$nginx_config_path/conf.d" "$backup_dir/conf.d"# 压缩备份文件
tar -czvf "$backup_main_dir/$backup_file.tar.gz" -C "$backup_main_dir" "nginx_backup_$(date +'%Y%m%d')"# 上传备份文件到OSS
/usr/local/bin/ossutil64 cp -f "$backup_main_dir/$backup_file.tar.gz" "oss://chb-backups/$env/nginx/$backup_file.tar.gz"# 删除前一天的备份目录
rm -rf "$backup_main_dir/nginx_backup_$(date -d '2 days ago' +'%Y%m%d')"# 输出备份完成信息
echo "Nginx配置文件已备份到: $backup_main_dir/$backup_file.tar.gz"
设置可执行权限
chmod +x nginx_conf_backup.sh
配置定时任务
crontab -e
0 3 * * * /data/script/nginx_conf_backup.sh
