2. RocketMQ单机安装

[root@localhost ~]# mqbroker -n IP:9876 &    ##改成本机IP地址

export JAVA_HOME=/usr/java/jdk1.8.0_221
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

[root@localhost data]# cd /soft
解压
[root@localhost soft]# unzip rocketmq-all-4.3.2-bin-release.zip
移动
[root@localhost soft]# mv rocketmq-all-4.3.2-bin-release /usr/local/rocketmq

编辑profile文件
[root@localhost rocket]# vi /etc/profile
将下面的配置添加到文件最底部
export PATH=$PATH:/usr/local/rocketmq/bin
export NAMESRV_ADDR=IP:9876                   ##手动更改为本地地址
保存，并退出。
更新profile文件
[root@localhost rocket]# source /etc/profile
说明：export NAMESRV_ADDR=localhost:9876是NAMESRV_ADDR环境变量

[root@localhost rocket]# mqnamesrv &
