1.免密码登陆脚本 sshFreeLogin.sh
集群服务器间相互访问:
首先有一个ip列表:
ip.list:
192.168.2.240 192.168.2.241 192.168.2.242
sshFreeLogin.sh:
#!/bin/bash #author: chongyuanHuang #blog: http://blog.sina.com.cn/huangchongyuan #QQ group: 191321336 #E-mail: 874450476@qq.com function Echo() { parameter=$1 name=$2 if [ $1 -ne 1 ]; then echo "Usage: $2 ip.list" echo " please input ip.list for freelogin and password next" exit 1 fi } function LocalSsh() { remote=$1 echo "------------------------------------------------------------" echo "Begin to set Local-Remote free login!" ssh-keygen -t rsa -P '' scp /root/.ssh/id_rsa.pub $1:/root/id_rsa.pub ssh $1 'cat /root/id_rsa.pub >> /root/.ssh/authorized_keys' ssh $1 'chmod 600 /root/.ssh/authorized_keys' echo "Local-Remote free login set Ok!" echo "------------------------------------------------------------" } if [ $# -eq 1 ]; then num=`awk 'END{print NR}' $1` echo 'Set free login ip.list:' for ((i=1;i<=$num;i++)); do ip=`cat $1 | sed -n ''$i'p'` echo $ip LocalSsh $ip done else Echo $# $0 fi
2.optZk.sh
zk集群操作脚本,配合免登陆设置,在一台机器上进行zk集群的启动,停止及查看状态等操作。
optZk.sh脚本:
#!/bin/bash #author: chongyuanHuang #blog: http://blog.sina.com.cn/huangchongyuan #QQ group: 191321336 #E-mail: 874450476@qq.com function Echo() { parameter=$1 name=$2 if [ $parameter -ne 2 ]; then echo "Usage: $name ip.list start/stop/status" echo " please input ip.list opt" exit 1 fi } function optZk() { ip=$1 opt=$2 echo "------------------------------------------------------------" echo "Begin to '$opt' '$ip' ZK:" ssh $1 '/usr/local/zookeeper/bin/zkServer.sh '$opt'' echo "------------------------------------------------------------" } if [ $# -eq 2 ]; then num=`awk 'END{print NR}' $1` for ((i=1;i<=$num;i++)); do ip=`cat $1 | sed -n ''$i'p'` echo $ip optZk $ip $2 done else Echo $# $0 fi
3、nimbus监控,一旦nimbus挂掉就重启,并把日志写到log里。
monitorNimbus.sh:
#!/bin/bash function Init() { date=`date +%Y%m%d%H%M%S` echo ''$date': Begin monitor nimbus.' > monitorNimbus.log } function MonitorNimbus() { for ((;;)); do num=`ps aux | grep nimbus | grep -v grep | wc -l` if [ $num -eq 0 ]; then date1=`date +%Y%m%d%H%M%S` echo ''$date1': nimbus is down, and restarting!' >> monitorNimbus.log storm nimbus& fi sleep 60 done } Init MonitorNimbus exit 1
