elasticSearch 集群通过脚本进行启停

#!/bin/bash
echo "start-----------"
hosts=("hadoop01" "hadoop02" "hadoop03")
for host in ${hosts[@]}
do
        ssh hadoop@$host << EOF
        cd ~/app/elasticsearch/bin
        ./elasticsearch -d -p ./pid 
        exit    
EOF
done
for host in ${hosts[@]}
do
        ssh hadoop@$host << EOF
        jps     
        exit    
EOF
done
echo "end-----------------"

以下是关闭集群的脚本

#!/bin/bash
echo "start-----------"
hosts=("hadoop01" "hadoop02" "hadoop03")
for host in ${hosts[@]}
do
        ssh hadoop@$host << EOF
        jps     
        exit    
EOF
done
for host in ${hosts[@]}
do
        ssh hadoop@$host << "EOF"
        pid=`jps | grep "Elasticsearch" | gawk '{ print $1 }'`
        if [[ ${pid} && -n ${pid} ]];
                then  kill -9  ${pid}; 
        fi      
        exit    
EOF
done
for host in ${hosts[@]}
do
        ssh hadoop@$host << EOF
        jps     
        exit    
EOF
done
echo "end-----------------"
