#!/bin/bash while read id;do ip=`echo $id | awk '{print $1}'` user=`echo $id | awk '{print $2}'` passwd=`echo $id | awk '{print $3}'` ./copy-key.exp $ip $user $passwd done <host.list |

虚拟机同步时间
暂时使用脚本，后期可用crontab实现

#!/bin/bash cmd="ntpdate -u time.windows.com" cmd2="hwclock -w" ansible annhe -m command -a "$cmd" ansible annhe -m command -a "$cmd2" ansible annhe -m command -a "date" |
利用ansible更改salt master

#!/bin/bash [ $# -lt 2 ] && echo "args error" && exit 1 oldmaster="192.168.60.10" newmaster="192.168.60.100" group=$1 saltgroup=$2 salt-key -d "$saltgroup" ansible $group -m command -a "cp /etc/salt/minion /etc/salt/minion.bak" ansible $group -m command -a "sed -i 's/$oldmaster/$newmaster/g' /etc/salt/minion" ansible $group -m command -a "rm -f /etc/salt/pki/minion/minion_master.pub" ansible $group -m command -a "/etc/init.d/salt-minion restart" ansible $group -m command -a "/etc/init.d/salt-minion status" ansible $group -m command -a "tail /var/log/salt/minion" |
copy文件
用ansible copy设置软件源的脚本并执行
|
1 2 3 |
ansible hadoop -m copy -a "src=/srv/salt/repo.sh dest=/tmp/repo.sh owner=root group=root mode=0755" ansible hadoop -m command -a "ls -l /tmp/repo.sh" ansible hadoop -m command -a "/tmp/repo.sh" |
repo.sh用于设置软件源
