下載並解壓安裝包到 /usr/local/rocketmq/rocketmq-all-4.7.0-bin-release
修改配置文件vim /etc/profile 添加如下幾行：
export NAMESRV_ADDR=127.0.0.1:9876
export ROCKETMQ_HOME=/usr/local/rocketmq/rocketmq-all-4.7.0-bin-release
export PATH=$JAVA_HOME/bin:$ROCKETMQ_HOME/bin:$PATH
記住/etc/profile中JAVA_HOME路徑爲：/usr/local/src/jdk1.8.0_161
使rocketmq的配置生效
source /etc/profile
cat /etc/profile
進入rocketmq/bin目錄，修改runserver.sh runbroker.sh 和 tools.sh
把：
[ ! -e "$JAVA_HOME/bin/java" ] && JAVA_HOME=$HOME/jdk/java
[ ! -e "$JAVA_HOME/bin/java" ] && JAVA_HOME=/usr/java
[ ! -e "$JAVA_HOME/bin/java" ] && error_exit "Please set the JAVA_HOME variable in your environment, We need java(x64)!"
改爲：
[ ! -e "$JAVA_HOME/bin/java" ] && JAVA_HOME=/usr/local/src/jdk1.8.0_161
#[ ! -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)!"
runserver.sh
找到以下配置，將xms/xmx/xmn 分別修改成以下數值（視機器配置而定）
JAVA_OPT="${JAVA_OPT} -server -Xms512m -Xmx512m -Xmn256m -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m"
##保存
runbroker.sh
##具體數值視機器而定
JAVA_OPT="${JAVA_OPT} -server -Xms128m -Xmx256m -Xmn256m"
##保存
rocketmq/conf中找到broker.conf，添加
namesrvAddr=127.0.0.1:9876
brokerIP1=47.107.185.200
分別後臺啓動
nohup sh mqnamesrv &
nohup sh mqbroker -n localhost:9876 autoCreateTopicEnable=true &
mqbroker的啓動命令爲：
nohup sh mqbroker -n localhost:9876 -c ../conf/broker.conf autoCreateTopicEnable=true &
查看mqbroker是否連接上mqnamesrv
sh mqadmin clusterList -n localhost:9876
sh mqadmin clusterList -n 47.107.185.200:9876
啓動日誌：
tail -f ~/logs/rocketmqlogs/namesrv.log
啓動錯誤日誌：
rocketmq/bin/nohup.out
查看是否啓動：
ps -ef | grep namesrv
ps -ef | grep mqbroker
或
ss -antulp |grep 9876
3、rocketmq服務關閉
關閉namesrv服務：sh ./mqshutdown namesrv
關閉broker服務 ：sh ./mqshutdown broker
你想創建一個名爲"tx-mq-TOPIC" 的主題。可以使用如下命令
目錄:rocketmq/bin
./mqadmin updateTopic -n localhost:9876 -b localhost:10911 -t tx-mq-TOPIC2
注意：ip和端口號
