CentOS7-Hive

Hive操作脚本（hive.sh {start|stop|restart|status}）

注意：此脚本安装于Hive服务端。

cd /usr/local/bin
sudo vi hive.sh

脚本内容如下：

#!/bin/bash
HIVE_LOG_DIR=/home/vagrant/modules/apache-hive-2.3.4-bin/logs
mkdir -p $HIVE_LOG_DIR
# 检查进程是否运行正常，参数1为进程名，参数2为进程端口
function check_process()
{
    pid=$(ps -ef 2>/dev/null | grep -v grep | grep -i $1 | awk '{print $2}')
    ppid=$(netstat -nltp 2>/dev/null | grep $2 | awk '{print $7}' | cut -d '/' -f 1)
    echo $pid
    [[ "$pid" =~ "$ppid" ]] && [ "$ppid" ] && return 0 || return 1
}
function hive_start()
{
    metapid=$(check_process HiveMetastore 9083)
    cmd="nohup hive --service metastore >$HIVE_LOG_DIR/metastore.log 2>&1 &"
    cmd=$cmd" sleep 4; hdfs dfsadmin -safemode wait >/dev/null 2>&1"
    [ -z "$metapid" ] && eval $cmd || echo "Metastroe is running.(${HOSTNAME})"
    server2pid=$(check_process HiveServer2 10000)
    cmd="nohup hive --service hiveserver2 >$HIVE_LOG_DIR/hiveServer2.log 2>&1 &"
    [ -z "$server2pid" ] && eval $cmd || echo "HiveServer2 is running.(${HOSTNAME})"
}
function hive_stop()
{
    metapid=$(check_process HiveMetastore 9083)
    [ "$metapid" ] && kill $metapid || echo "Metastore stop.(${HOSTNAME})"
    server2pid=$(check_process HiveServer2 10000)
    [ "$server2pid" ] && kill $server2pid || echo "HiveServer2 stop.(${HOSTNAME})"
}
function hive_status()
{
    check_process HiveMetastore 9083 >/dev/null && echo "Metastore is running.(${HOSTNAME})" || echo "Metastore stop.(${HOSTNAME})"
    check_process HiveServer2 10000 >/dev/null && echo "HiveServer2 is running.(${HOSTNAME})" || echo "HiveServer2 stop.(${HOSTNAME})"
}
case $1 in
"start")
    hive_start
    sleep 3
    hive_status
    ;;
"stop")
    hive_stop
    sleep 5
    hive_status
    ;;
"restart")
    hive_stop
    sleep 3
    hive_start
    sleep 3
    hive_status
    ;;
"status")
    hive_status
    ;;
*)
    echo Invalid Args!
    echo 'Usage: '$(basename $0)' start|stop|restart|status'
    ;;
esac

设置脚本执行权限：

sudo chmod +x hive.sh
sudo chown vagrant:vagrant hive.sh

操作指引：

# 启动
hive.sh start
# 关闭 
hive.sh stop
# 重启 
hive.sh restart
# 状态
hive.sh status

Hive服务启动脚本（_start-hive-server）_

cd /usr/local/bin
sudo vi start-hive-server

脚本内容如下：

#!/bin/bash
echo "start hive metastore & hiveserver2-------------------------------------------------"
for i in bigdata-node1
do 
ssh $i "source /etc/profile;/usr/local/bin/hive.sh start"
done
sleep 3s
exit 0

设置脚本执行权限：

sudo chmod +x start-hive-server
sudo chown vagrant:vagrant start-hive-server

Hive服务停止脚本（_stop-hive-server）_

cd /usr/local/bin
sudo vi stop-hive-server

脚本内容如下：

#!/bin/bash
echo "stop hive metastore & hiveserver2-------------------------------------------------"
for i in bigdata-node1
do 
ssh $i "source /etc/profile;/usr/local/bin/hive.sh stop"
done
sleep 3s
exit 0

设置脚本执行权限：

sudo chmod +x stop-hive-server
sudo chown vagrant:vagrant stop-hive-server

Hive服务状态查看脚本（_status-hive-server）_

cd /usr/local/bin
sudo vi status-hive-server

脚本内容如下：

#!/bin/bash
echo "status hive metastore & hiveserver2-------------------------------------------------"
for i in bigdata-node1
do 
ssh $i "source /etc/profile;/usr/local/bin/hive.sh status"
done
sleep 3s
exit 0

设置脚本执行权限：

sudo chmod +x status-hive-server
sudo chown vagrant:vagrant status-hive-server

分发（选做）：

# 使用root账户分发至其他节点
sudo scp -r /usr/local/bin/*-hive-server root@bigdata-node2:/usr/local/bin/
sudo scp -r /usr/local/bin/*-hive-server root@bigdata-node3:/usr/local/bin/
