将文件发送到多个主机

将文件发送到多个主机

以下是我的脚本，For 循环有效。完美。不起作用的是获取主机名并在所有主机名中执行“SendFiles”循环。知道如何解决这个问题，它会从 Phy_Hosts 变量中获取主机名。

vmfarm1现在，它所做的只是在主机中重复 7 次。我也可能必须使用#!/usr/bin/env bash环境吗？

#!/bin/bash
#Location where bash scripts are located.

phy_ssh=/opt/wiki_scripts/servers.sh 
vm_ssh=/opt/wiki_scripts/virtualservers.sh

#Hosts where we will ssh into.
Phy_Hosts=(vmfarm1 p12 barclay maximus backupfirefly accountant 10.6.6.90)

SendFiles () {
        host=$1
        ssh root@${Phy_Hosts} 'bash -s' < ${phy_ssh}
        ssh root@${Phy_Hosts} cat /root/phy_machines.txt >>  /opt/wiki_scripts/phy_machines.txt
}

hostCount=${#Phy_Hosts[@]}

# backup databases
for ((i=0; i<${hostCount}; i++))
do
        host=${Phy_Hosts[$i]}
        SendFiles ${host}
done

exit 0

Currently:

SendFiles () {
        local host="$1"
        ssh "root@$host" 'bash -s' <"$phy_ssh"
        ssh "root@$host" cat /root/phy_machines.txt
}

SendFiles1 () {
        local host1="$1"
        ssh "root@$host1" 'bash -s' <"$vm_ssh"
        ssh "root@$host1" cat /root/vm_machines.txt
}


# Save the following data to the phy_machine file.

建议：

#!/bin/bash

# Location where bash scripts are located.
phy_ssh=/opt/wiki_scripts/servers.sh 

# Hosts where we will ssh into.
Phy_Hosts=( vmfarm1 p12 barclay maximus backupfirefly accountant 10.6.6.90 )

SendFiles () {
        local host="$1"
        ssh "root@$host" 'bash -s' <"$phy_ssh"
        ssh "root@$host" cat /root/phy_machines.txt
}

# backup databases
for host in "${Phy_Hosts[@]}"; do
        SendFiles "$host"
done >/opt/wiki_scripts/phy_machines.txt
  • 可以直接对数组进行循环，无需使用索引。
  • 您从未host在函数中使用过该变量。
  • 一般清理，包括删除未使用的变量vm_ssh、双引号变量扩展以及删除exit 0末尾不需要的变量。
  • 输出重定向从函数内部移至循环for。这可能不是必要的，或者如果您希望ssh函数中的第一次调用输出某些内容，这可能确实是错误的做法，但它使函数更清晰。

经过几次评论迭代后：

仅定义该SendFiles函数一次（稍后的定义将覆盖之前的定义）。让它带走全部它需要为任何特定主机集运行的信息。

#!/bin/bash

# Location where bash scripts are located.
phy_ssh=/opt/wiki_scripts/servers.sh
vm_ssh=/opt/wiki_scripts/virtualservers.sh
others_ssh=/opt/wiki_scripts/others.sh

# Hosts where we will ssh into.
Phy_Hosts=( vmfarm1 p12 barclay maximus backupfirefly accountant 10.6.6.90 )
Vm_Hosts=( icinga.stacc.ee ldap.stacc.ee mail.stacc.ee openvpn.stacc.ee dns.stacc.ee redmine.stacc.ee owncloud.stacc.ee www.stacc.ee git.stacc.ee )
SomeOther_list ( more machines )

SendFiles () {
        local host="$1"
        local script="$2"
        local remotefile="$3"

        ssh "root@$host" 'bash -s' <"$script"
        ssh "root@$host" cat "$remotefile"
}

# backup databases
for host in "${Phy_Hosts[@]}"; do
        SendFiles "$host" "$phy_ssh" /root/phy_machines.txt
done >/opt/wiki_scripts/phy_machines.txt

for host in "${Vm_Hosts[@]}"; do
        SendFiles "$host" "$vm_ssh" /root/vm_machines.txt
done >/opt/wiki_scripts/vm_machines.txt

# and then, for example
for host in "${SomeOther_list[@]}"; do
        SendFiles "$host" "$others_ssh" /root/other_machines.txt
done >/opt/wiki_scripts/other_machines.txt
