- 这是一个基于python的小工具
- 使用此工具之前需要手工编写一个主机列表文件
1. 安装依赖包:
Ubuntu:
apt-get -y install rsync python-paramiko python-pexpect
Redhat/CentOS:
yum -y install rsync python-paramiko python-pexpect
低版本向高版本兼容：
* 安装最新pip:
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py; python get-pip.py
* 安装库文件:
Ubuntu:
apt-get install build-essential libssl-dev libffi-dev python-dev
Redhat/CentOs:
yum install gcc libffi-devel python-devel openssl-devel
* 安装paramiko
pip install paramiko
2. 获取代码:
git clone https://github.com/bw-y/hhdp.git
chmod 755 hhdp.py && mkdir -v /usr/local/hhdp
mv hhdp.py /usr/local/hhdp/
3. 创建主机列表文件:/etc/hosts_list
touch /etc/hosts_list # 文件内容说明见下文
4. 创建链接:
ln -sv /usr/local/hhdp/hhdp.py /usr/bin/hhdp
- 此文件默认路径: /etc/hosts_list
- 支持注释,任意行首
#时,此行内容不被读取 - 文件每行定义一个主机相关信息(ip,port,user,passwd,pkey),其中pkey为ssh使用key认证时,私钥文件的绝对路径
- 每行多个字段之间以一个空格隔开,字段内容由冒号定义属性. 例如:
ip:192.168.1.10 port:22 pkey:/opt/id_rsa - 除ip字段外,其它属性都有默认值,可不填写.
- ip [必填项]可以是ip和fqdn. 例:
ip:192.168.1.10或:ip:node1.bw-y.com - port [可选项]调用ssh所需端口号. 例:
port:1022默认值:port:22 - user [可选项]调用ssh所需用户名. 例:
user:bw_y默认值:user:root - passwd [可选项]调用ssh所需密码. 例:
passwd:ssh_password默认值:passwd:key(使用pkey对应的值,passwd不等于key时,则直接使用密码) - pkey [可选项]调用ssh所需私钥. 例:
pkey:/opt/pro/id_rsa默认值: 当前用户家目录下的.ssh目录中的id_rsa, 此文件不存在时直接报错.
# cat /etc/hosts_list
ip:192.168.5.22 user:bw-y
ip:192.168.5.12 passwd:redhat
ip:lab.bw-y.com
ip:192.168.5.43 pkey:/opt/id_rsa
ip:node1.bw-y.com port:1002 pkey:/opt/bw_id_rsa
注: 如果需要执行的命令过长,或者命令中有用到单引号或其它特殊符号,可以先写一个简单的脚本,hhdp -f将其推送到每个节点上,然后hhdp -c调用脚本执行
例1. 将命令 `uptime` 在每个节点上执行
# hhdp -c 'uptime'
23:52:49 up 1 day, 9:43, 0 users, load average: 0.22, 0.30, 0.33
23:52:49 up 1 day, 9:49, 2 users, load average: 0.00, 0.00, 0.00
23:52:50 up 1 day, 9:48, 0 users, load average: 0.26, 0.13, 0.08
23:52:50 up 2 days, 21:40, 3 users, load average: 0.34, 0.13, 0.08
例2. 将命令 `facter hostname;facter ipaddress;uptime|grep "1 day";echo` 在每个节点上执行
# hhdp -c 'hostname;facter ipaddress;uptime|grep "1 day";echo'

例3. 将本地文件/opt/file1同步到每个节点的相同路径
# hhdp -f /opt/file1
/opt/file1 => 192.168.5.18:/opt/file1 2015/10/07 00:06:17 -> 00:06:20 ok
/opt/file1 => 192.168.5.17:/opt/file1 2015/10/07 00:06:20 -> 00:06:24 ok
/opt/file1 => 192.168.5.16:/opt/file1 2015/10/07 00:06:24 -> 00:06:28 ok
/opt/file1 => 192.168.5.15:/opt/file1 2015/10/07 00:06:28 -> 00:06:31 ok
例4. 将本地文件/opt/file1同步到每个节点的/tmp/file2
# hhdp -f /opt/file1 /tmp/file2
/opt/file1 => 192.168.5.18:/tmp/file2 2015/10/07 00:07:42 -> 00:07:45 ok

/opt/file1 => 192.168.5.15:/tmp/file2 2015/10/07 00:07:53 -> 00:07:56 ok
例5. 获取刚才推荐文件的md5
# hhdp -c 'echo "$(hostname) $(md5sum /tmp/file2)"'

例6. 将本地目录/opt/dir同步到每个节点的相同位置
# hhdp -f /opt/dir
