remote_exec

linux服务器批量操作工具。

提供三个功能：

1. 批量上传文件
2. 以root用户批量执行命令
3. 批量下载文件

通过组合这三个功能能完成大多数Linux服务器上的操作。

特性

• 单文件分发，无依赖，兼容好
• 跨平台，可在Windows、Linux，x86、ARM环境中执行
• 任务固化，可重复使用，可对任务进行分组
• 可配置性好，支持多种远端环境

配置说明

服务器信息配置

config.yaml文件

port: 22
root-prompt: '#'
passwd-prompt: '.*assword.*'
timeout: 10
user: 'kehao'
passwd: '123456'
root-passwd: '123456'
hosts:
  - '172.18.0.3'
  - '172.18.0.4'
spc-hosts:
  - '127.0.0.1 23 123456 123456'

• port: ssh端口；
• root-prompt：root用户的提示信息，golang正则表达式；
• passwd-prompt：root用户输入password的提示信息，golang正则表达式；
• timeout：等待登录的超时时长，单位：秒；
• user：ssh登录用户；
• passwd：ssh登录密码；
• root-passwd：root用户密码；
• hosts：服务器IP地址列表；
• spc_hosts：特殊密码的服务器列表，格式：IP PORT 用户密码 root用户密码。

任务配置

command.yaml文件

put:
  - /home/kehao/test1.sh#/home/kehao
exec:
  - /bin/sh /home/kehao/test1.sh
get:
  - /home/kehao/result1.txt#/home/kehao/result

arthas:
  put:
    - /home/kehao/arthas.sh#/home/kehao
    - /home/kehao/jdk8.sh#/home/kehao
  exec:
    - /bin/sh /home/kehao/arthas.sh
    - /bin/sh /home/kehao/jdk8.sh
  get:
    - /home/kehao/arthas-result.txt#/home/kehao/result
    - /home/kehao/jdk8-result.txt#/home/kehao/result

• put：上传文件列表，格式：本地文件路径#远程目录名称，远程目录名称可缺省，默认与本地文件路径的目录名相同，ssh登录用户需要具有远程目录的写权限；
• exec：需要执行的命令列表，命令将以root用户执行；
• get：下载的文件列表，格式：远程文件路径#本地目录名称，本地目录名称可缺省，默认与远程文件路径的目录名相同，ssh登录用户需要具有远程文件的读权限。

使用方法

命令

批量上传

remote put

批量执行

remote exec

批量下载

remote get

参数

remote --help
remote execute tool

Usage:
  remote [command]

Available Commands:
  completion  Generate the autocompletion script for the specified shell
  exec        execute command on remote
  get         get file from remote
  help        Help about any command
  put         put file to remote

Flags:
  -c, --command string   Specify commands configuration (default "command.yaml")
  -f, --config string    Specify servers configuration (default "config.yaml")
  -h, --help             help for remote
  -m, --netmask string   ip filter, e.g. 192.168.1.1 192.168.1.1,192.168.1.2 192.168.0.0/24
  -t, --thread int       maximum number of concurrent (0 < t <= 16) (default 1)
  -v, --version          version for remote

Use "remote [command] --help" for more information about a command.

• 服务器配置文件（f），默认值config.yaml
• 命令配置文件（c），默认值command.yaml
• 最大并发数（t），0 < t <= 16，默认值1，开启并发执行能提高执行效率，但是输出结果会乱序
• IP地址过滤（m），默认为空，支持192.168.1.1、192.168.1.1,192.168.1.2、192.168.0.0/24三种写法，匹配的主机才会执行

使用样例

测试脚本：

test1.sh

echo "test1.sh" >/home/kehao/result1.txt
hostname -s >>/home/kehao/result1.txt
hostname -i >>/home/kehao/result1.txt
id >>/home/kehao/result1.txt
chown kehao: /home/kehao/result1.txt
echo "I am $(hostname -i) :)"
