nagios批量创建主机脚本

2024-12-07 技术教程

目的：实现批量主机文件和服务的创建，将服务就写到了主机文件中；

用户change.sh linux.template（主机服务模版） list.txt （主机IP对应列表）

catc change.sh

usage () {
echo -en "USAGE: $0 [host list] or $0 [template] [host list]\nFor ex ample: $0 host.template host.list(Field : [IP] [HOST NAME])\n" 1>&2
exit 1
}

if [ $# -gt 2 ];then
usage
exit 1
fi

case "$#" in
2)
template=$1
host_list=$2
;;
1)
template='host.template'
host_list=$1
;;
0)
# template='host.template'
# host_list='host.list'
usage
;;
esac

if [ ! -f "${template}" ];then
echo "template : ${template} not exist!" 1>&2
exit 1
fi

if [ ! -f "${host_list}" ];then
echo "host list : ${host_list} not exist!" 1>&2
exit 1
fi

cat ${host_list}| while read ip hostname
do
echo "${ip}"|grep -oP '^\d{1,3}(\.\d{1,3}){3}$' >/dev/null 2>&1 || Field='not ip'
if [ "${Field}" = 'not ip' ];then
echo "${ip} not ip!" 1>&2
exit 1
fi
host_cfg="${hostname}-${ip}.cfg"
cp ${template} ${host_cfg}
sed -i "s/HOST_NAME/${hostname}/g;s/ADDRESS/${ip}/g" ${host_cfg}
done

cat linux.template

define host{
use linux-server,hosts-pnp
host_name HOST_NAME
alias HOST_NAME
address ADDRESS
}
