常用脚本

1、修改rocketmq参数

#!/bin/bash
pid_namesrv=`ps -ef | grep rocketmq | grep java |grep namesrv.properties | grep -v grep | awk '{print $2}'`
for i in $pid_namesrv
do  
    user_roc1=`ps -ef | grep $i | grep -v grep | awk '{print $1}'`
    sudo user_roc=`cat /etc/passwd | grep $user_roc1 | awk -F : '{print $1}'`
    ip_namesrv=`hostname -I | awk '{print $1}'`
    conf_namesrv=`ps -ef | grep $i | grep -v grep | awk -F "-c" '{print $NF}'`
    port_namesrv=`cat $conf_namesrv | grep listenPort | awk '{print $NF}'`
    soc_namesrv="$ip_namesrv:$port_namesrv"
    conf_namesrv2=`dirname $conf_namesrv` 
    cd $conf_namesrv2 && cd ../bin
    dir_namesrv=`pwd`
    if [ -f mqadmin ];then
        sudo chmod +x mqadmin
        sudo su - $user_roc -c "$dir_namesrv/mqadmin  updateBrokerConfig -n '$soc_namesrv' -c DefaultCluster -k haSendHeartbeatInterval -v 5000"
    else
            echo "the mqadmin file not exist."
            exit 3
    fi
done
