服务器：192.168.21.133一、主机列表
# cat host.list
lvs-01 192.168.1.1
lvs-02 192.168.1.2
mysql-01 192.168.1.3
mysql-02 192.168.1.4
web-01 192.168.1.5
web-02 192.168.1.6
二、部署脚本
# cat create_host.sh
#!/bin/sh
HOSTFILE='/usr/local/nagios/etc/objects'
cat >>$HOSTFILE/host_test.cfg<<EOF
#####################################################
#
# HOST DEFINITION BY ZHANGYILING AT 20190816
#
#####################################################
EOF
exec <host.list
while read line
do
echo "#host:`echo $line|awk '{print $1}'`|ip:`echo $line|awk '{print $2}'`">>$HOSTFILE/host_test.cfg
echo "define host {" >>$HOSTFILE/host_test.cfg
echo " use linux-server">>$HOSTFILE/host_test.cfg
echo " hostnmae `echo $line|awk '{print $1}'`">>$HOSTFILE/host_test.cfg
echo " alias `echo $line|awk '{print $1}'`">>$HOSTFILE/host_test.cfg
echo " address `echo $line|awk '{print $2}'`">>$HOSTFILE/host_test.cfg
echo "}">>$HOSTFILE/host_test.cfg
echo >>$HOSTFILE/host_test.cfg
done
>tmp.host
exec <host.list
i=1
while read line
do
if [ $i -eq 6 ];then
echo -n "`echo $line|awk '{print $1}'`" >>tmp.host
else
echo -n "`echo $line|awk '{print $1}'`", >>tmp.host
fi
((i++))
done
members=`head -1 tmp.host`
cat >>$HOSTFILE/host_test.cfg<<EOF
