• RocketMQ系列:mqadmin命令行使用总览


    1.介绍

    rocketmq由consumer,producer,broker三大块组成,如何对这三类服务进行运维操作呢?这里介绍rocketmq自带的命令行工具:mqadmin

    2.位置

    项目:https://github.com/apache/rocketmq.git

    ${PWD}/rocketmq/distribution/bin/mqadmin

    3.脚本

    3.1 mqadmin

    #这里ROCKETMQ_HOME对应的是rocketmq的主目录
    if
    [ -z "$ROCKETMQ_HOME" ] ; then ## resolve links - $0 may be a link to maven's home PRG="$0" # need this for relative symlinks while [ -h "$PRG" ] ; do ls=`ls -ld "$PRG"` link=`expr "$ls" : '.*-> (.*)$'` if expr "$link" : '/.*' > /dev/null; then PRG="$link" else PRG="`dirname "$PRG"`/$link" fi done saveddir=`pwd` ROCKETMQ_HOME=`dirname "$PRG"`/.. # make it fully qualified ROCKETMQ_HOME=`cd "$ROCKETMQ_HOME" && pwd` cd "$saveddir" fi export ROCKETMQ_HOME #这里实际使用的另外一个脚本tools.sh sh ${ROCKETMQ_HOME}/bin/tools.sh org.apache.rocketmq.tools.command.MQAdminStartup $@

    3.2 tools.sh

    主要作用就是设置JVM参数,然后使用java 启动对应classs

    #===========================================================================================
    # Java Environment Setting
    #===========================================================================================
    error_exit ()
    {
        echo "ERROR: $1 !!"
        exit 1
    }
    
    [ ! -e "$JAVA_HOME/bin/java" ] && JAVA_HOME=$HOME/jdk/java
    [ ! -e "$JAVA_HOME/bin/java" ] && JAVA_HOME=/usr/java
    [ ! -e "$JAVA_HOME/bin/java" ] && error_exit "Please set the JAVA_HOME variable in your environment, We need java(x64)!"
    
    export JAVA_HOME
    export JAVA="$JAVA_HOME/bin/java"
    export BASE_DIR=$(dirname $0)/..
    export CLASSPATH=.:${BASE_DIR}/conf:${CLASSPATH}
    
    #===========================================================================================
    # JVM Configuration
    #===========================================================================================
    JAVA_OPT="${JAVA_OPT} -server -Xms1g -Xmx1g -Xmn256m -XX:PermSize=128m -XX:MaxPermSize=128m"
    JAVA_OPT="${JAVA_OPT} -Djava.ext.dirs=${BASE_DIR}/lib:${JAVA_HOME}/jre/lib/ext"
    JAVA_OPT="${JAVA_OPT} -cp ${CLASSPATH}"
    
    #这里是实际调用 $JAVA ${JAVA_OPT} $@
