Question

我正在尝试使用来自hosts文件特定部分的shell脚本从属性文件（ansible hosts文件）中获取值。

所以我有这个主机文件：

[windows]
myd-vm14945.company.net
myd-vm01431.company.net

[windows-web]
vmpweb314.company.net

[linux]
myd-vm11409.company.net
myd-vm14296.company.net
myd-vm20125.company.net
mydvm0091.company.net

我希望运行此脚本，当 Linux 部分下的每个服务器都应该替换shell脚本中的参数 $ {REMOTE_SERVER} 时：

#add remote server to ansible host known_host file
ssh-keyscan ${REMOTE_SERVER}>> /root/.ssh/known_hosts
#remmber password
sshpass -p ROOT_PASSWORD ssh root@${REMOTE_SERVER}

这样最终结果就是这样：

#add remote server to ansible host known_host file
ssh-keyscan myd-vm11409.company.net >> /root/.ssh/known_hosts
ssh-keyscan myd-vm14296.company.net>> /root/.ssh/known_hosts
#remmber password
sshpass -p ROOT_PASSWORD ssh root@myd-vm11409.company.net
sshpass -p ROOT_PASSWORD ssh root@myd-vm14296.company.net

等等......对于Linux下的所有值。

如果您真的想通过bash进行此操作，请参阅以下awk魔法，部分取自Read certain key from certain section of ini file (sed/awk ?)

因此，您可以创建以下脚本，调整您的库存文件和部分并运行它！

<强> addkeys.sh

#!/bin/bash
INVENTORY="inventory.ini"
SECTION="[linux]"

I_HOSTS="$(awk -v section="$SECTION" ' # Enable a flag when the line is like your section
$0==section{ f=1; next }               # For any lines with [ disable the flag
/\[/{ f=0; next }                      # If flag is set - print the line
f && $0' "$INVENTORY")"

for I_HOST in $I_HOSTS
do
    #add remote server to ansible host known_host file
    echo "ssh-keyscan "$I_HOST" >> /root/.ssh/known_hosts"
    #remmber password
    echo "sshpass -p ROOT_PASSWORD ssh "root@$I_HOST""
done

使用echo sshpass和keyscan commads的结果：

ssh-keyscan myd-vm11409.company.net >> /root/.ssh/known_hosts
sshpass -p ROOT_PASSWORD ssh root@myd-vm11409.company.net
ssh-keyscan myd-vm14296.company.net >> /root/.ssh/known_hosts
sshpass -p ROOT_PASSWORD ssh root@myd-vm14296.company.net
ssh-keyscan myd-vm20125.company.net >> /root/.ssh/known_hosts
sshpass -p ROOT_PASSWORD ssh root@myd-vm20125.company.net
ssh-keyscan mydvm0091.company.net >> /root/.ssh/known_hosts
sshpass -p ROOT_PASSWORD ssh root@mydvm0091.company.net

使用特定节中的shell从属性文件中获取值
