Linux lnmp安装coscmd备份网站数据到cos

下载与安装coscmd

如果系统没有pip，pip安装参考：https://www.blyoo.com/5237.html

通过 pip 安装

执行pip命令进行安装：

pip install coscmd

安装成功之后，用户可以通过-v或者–version命令查看当前的版本信息。

pip 更新

安装完成后，执行以下命令进行更新：

pip install coscmd -U

配置

在电脑上创建一个.cos.conf

或者直接在linux里创建root目录里创建.cos.conf也行，但是还得通过vim编辑，有点麻烦了，

然后把conf文件上传到服务器，root目录里，

内容如下，修改成自己的，

secret_id：密钥中的SecretId
secret_key：密钥中的SecretKey
bucket：存储桶名称
region：存储桶所在地域
max_thread：上传线程，服务器带宽小那就设置小一点，
part_size：分块大小，服务器带宽小那就设置小一点，
retry：重试次数

[common]
secret_id = AKIDA6wUmImTMzvXZNbGLCgtusZ2E8mG**** ##
secret_key = TghWBCyf5LIyTcXCoBdw1oRpytWk****
bucket = configure-bucket-1250000000
region = ap-chengdu
max_thread = 5
part_size = 1
retry = 5
timeout = 60
schema = https
verify = md5
anonymous = False

或者

直接执行，自动在root目录生成conf文件

coscmd config -a AChT4ThiXAbpBDEFGhT4ThiXAbp**** -s WE54wreefvds3462refgwewe**** -b configure-bucket-1250000000 -r ap-chengdu

测试上传

上传文件命令格式

请将 “<>” 中的参数替换为您需要上传的本地文件路径（localpath），以及 COS 上存储的路径（cospath）。

coscmd upload <localpath> <cospath>

例如

上传本机root目录里1.jpg文件到cos根目录

coscmd upload /root/1.jpg /

上传本机root目录里1.jpg文件到coshello目录

coscmd upload /root/1.jpg hello/

备份

我是直接修改的lnmp自带的backup.sh备份文件，

例如创建一个文件命名为backup_cos.sh

然后把文件上传root目录，

在给backup_cos.sh文件权限，

chmod -R 755 /root/backup_cos.sh

测试备份上传

/root/backup_cos.sh

备份脚本如下

注意

在centos可以直接coscmd,

在debian系统需要写绝对路径,/usr/local/bin/coscmd

其他系统不知,没用过,

#!/usr/bin/env bash

如果测试备份上传没问题，来到下一步，

设置Crontab定时执行

crontab操作参考：http://www.vpser.net/manage/crontab.html

添加crontab定时执行任务

crontab -e

如果是vi编辑器，首先按i键，在文件末尾按crontab命令格式输入，再按ESC键，再输入:wq 回车即可。

设置每天凌晨1点钟备份开始，

0 1 * * * /root/backup_cos.sh
