Linux操作系统 作者:luashin 时间:2016-03-09 19:49:01 0 删除 编辑
1、我的hosts配置

192.168.1.107  storm_supervisor4
192.168.1.108  storm_supervisor5
192.168.1.109  storm_supervisor6

2、我的storm配置

storm.cluster.mode: "distributed"
storm.local.mode.zmq: false
 
ui.port: 8080

supervisor.slots.ports:
  - 6700
  - 6701

  - 6705
  - 6706
  - 6707
  - 6708
  - 6709
   
supervisor.childopts: "-Xmx2048m"
supervisor.worker.start.timeout.secs: 240
supervisor.worker.timeout.secs: 30
supervisor.monitor.frequency.secs: 3
supervisor.heartbeat.frequency.secs: 5
supervisor.enable: true
 
worker.childopts: "-Xmx4096m"
topology.max.spout.pending: 5000
 
storm.zookeeper.session.timeout: 5000
storm.zookeeper.connection.timeout: 3000
storm.zookeeper.retry.times: 6
storm.zookeeper.retry.interval: 2000
storm.zookeeper.retry.intervalceiling.millis: 30000
 
storm.thrift.transport: "backtype.storm.security.auth.SimpleTransportPlugin"
storm.messaging.transport: "backtype.storm.messaging.netty.Context"
storm.messaging.netty.server_worker_threads: 50
storm.messaging.netty.client_worker_threads: 50
storm.messaging.netty.buffer_size: 20971520
storm.messaging.netty.max_retries: 100
storm.messaging.netty.max_wait_ms: 1000
storm.messaging.netty.min_wait_ms: 100

3、nimbus节点部署
# 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
 
## 监控页面地址参数
MON_SRV_IPADDR="192.168.1.103"
MON_SRV_PORT="8080"
 
## 是否已正确扫描
SCAN_FLAG=0
 
## 工作基路径
BASE_PATH="/data/scripts"
 
## 异常 storm Supervisor 主机地址列表
FAIL_SUPERVISOR_LIST="${BASE_PATH}/fail_supervisor.txt"
 
#---------------------------------------------------------------------------------------------------
## 重启storm的nimbus服务
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
}
 
#---------------------------------------------------------------------------------------------------
## 1、检查监控页面是否正常【8080端口不通的情况】
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
 
#---------------------------------------------------------------------------------------------------
## 2、将监控页面抓取内容与本地hosts内容进行差异比较,以确定是否存在异常的 storm supervisor 服务
curl -s http://${MON_SRV_IPADDR}:${MON_SRV_PORT}/ | sed 's//\n/g' | awk -F '<' '/^storm_/{print $1}' | awk '!/nimbus/{print}' | sort > ${BASE_PATH}/supervisor_list_from_page.txt
 
## 如果获取的storm nimbus监控页面数据为空,代表storm nimbus服务存在异常
[[ -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
 
#---------------------------------------------------------------------------------------------------
## 3、获得异常的 storm supervisor 服务的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
 
#---------------------------------------------------------------------------------------------------
## 4、远程重启 storm supervisor 服务
/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)

4、supervisor节点部署
# 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 &
