192.168.1.101  storm_zk2
192.168.1.102  storm_zk3
 
192.168.1.103  storm_nimbus
 
192.168.1.104  storm_supervisor1
192.168.1.105  storm_supervisor2
192.168.1.106  storm_supervisor3

三、nimbus節點部署

# vim /data/scripts/monitor_status_for_storm.sh

#!/bin/sh
PATH=/sbin:/bin:/usr/sbin:/usr/bin:/usr/local/bin:/usr/local/sbin
 
. /etc/profile
 
## 監控頁面地址參數
MON_SRV_IPADDR="192.168.1.103"
MON_SRV_PORT="8080"
 
## 是否已正確掃描
SCAN_FLAG=0
 
## 工做基路徑
BASE_PATH="/data/scripts"
 
## 異常 storm Supervisor 主機地址列表
FAIL_SUPERVISOR_LIST="${BASE_PATH}/fail_supervisor.txt"
 
#---------------------------------------------------------------------------------------------------
## 重啓storm的nimbus服務
function restart_storm_nimbus_server() 
{
    [[ -n `ps aux | grep java | grep storm` ]] && kill -9 `ps aux | grep java | grep storm | awk '{print $2}'`
    nohup /usr/local/storm/bin/storm nimbus >/dev/null 2>&1 &
    nohup /usr/local/storm/bin/storm ui >/dev/null 2>&1 &
     
    sleep 30
}
 
#---------------------------------------------------------------------------------------------------
## 一、檢查監控頁面是否正常【8080端口不通的狀況】
for ((i=0; i<3; i++)); do
    RETVAL=`/usr/bin/nmap -n -sS -p ${MON_SRV_PORT} ${MON_SRV_IPADDR} | grep open`
    [[ -n "${RETVAL}" ]] && SCAN_FLAG=1;break || sleep 10
done
 
[[ ${SCAN_FLAG} -ne 1 ]] && restart_storm_nimbus_server
 
#---------------------------------------------------------------------------------------------------
## 二、將監控頁面抓取內容與本地hosts內容進行差別比較，以肯定是否存在異常的 storm supervisor 服務
curl -s http://${MON_SRV_IPADDR}:${MON_SRV_PORT}/ | sed 's/<td>/<td>\n/g' | awk -F '<' '/^storm_/{print $1}' | awk '!/nimbus/{print}' | sort > ${BASE_PATH}/supervisor_list_from_page.txt
 
## 若是獲取的storm nimbus監控頁面數據爲空，表明storm nimbus服務存在異常
[[ -z `sed '/^$/d' ${BASE_PATH}/supervisor_list_from_page.txt` ]] && restart_storm_nimbus_server
 
sort -nr ${BASE_PATH}/supervisor_list_from_page.txt ${BASE_PATH}/supervisor_list.txt | uniq -u > ${BASE_PATH}/supervisor_list_for_failed.txt
[[ -z `sed '/^$/d' ${BASE_PATH}/supervisor_list_for_failed.txt` ]] && rm -f ${BASE_PATH}/supervisor_list_for_failed.txt && exit 0
 
#---------------------------------------------------------------------------------------------------
## 三、得到異常的 storm supervisor 服務的IP地址列表
echo "[fail_supervisor]" >> ${FAIL_SUPERVISOR_LIST}
 
for SUPERVISOR_NAMEADDR in `cat ${BASE_PATH}/supervisor_list_for_failed.txt`
do
    TEMP_IPADDR=`grep -w ${SUPERVISOR_NAMEADDR} /etc/hosts | grep -v '#' | awk '{print $1}' | tail -1`
    echo "${TEMP_IPADDR}" >> ${FAIL_SUPERVISOR_LIST}
    IPLIST="${IPLIST} ${TEMP_IPADDR}"
done
 
#---------------------------------------------------------------------------------------------------
## 四、遠程重啓 storm supervisor 服務
/usr/local/bin/ansible -i ${FAIL_SUPERVISOR_LIST} fail_supervisor -m shell -a "/data/scripts/restart_storm_service.sh"
rm -f ${FAIL_SUPERVISOR_LIST}

# vim /data/scripts/supervisor_list.txt

storm_supervisor1
storm_supervisor2
storm_supervisor3
storm_supervisor4
storm_supervisor5
storm_supervisor6

# touch /var/run/check_storm.lock

# crontab -e

*/2 * * * * (flock --timeout=0 /var/run/check_storm.lock /data/scripts/monitor_status_for_storm.sh >/dev/null 2>&1)

四、supervisor節點部署

# vim /data/scripts/restart_storm_service.sh

#!/bin/sh
PATH=/sbin:/bin:/usr/sbin:/usr/bin:/usr/local/bin:/usr/local/sbin
 
. /etc/profile
[[ -n `ps aux | grep java | grep storm` ]] && kill -9 `ps aux | grep java | grep storm | awk '{print $2}'`
nohup /usr/local/storm/bin/storm supervisor >/dev/null 2>&1 &
