2.2.2、集群安装（Local 模式）

Local 模式 - 多节点（集群）多副本模式-同步双写环境部署

集群主机

共计4台虚拟机，2 master, 2 slave。

下载安装

下载最新安装包： http://rocketmq.apache.org/dowloading/releases/

下载并安装最新稳定版的RocketMQ.

[root@rockketmq ~]# cd /usr/local/src && wget https://mirrors.bfsu.edu.cn/apache/rocketmq/5.0.0/rocketmq-all-5.0.0-bin-release.zip --no-check-certificate
[root@rockketmq local]# unzip rocketmq-all-5.0.0-bin-release.zip -d /usr/local/
[root@rockketmq local]# cd .. && mv rocketmq-all-5.0.0-bin-release/ rocketmq

修改JVM默认配置（物理机器内存为8G）

[root@localhost rocketmq]# vi bin/runserver.sh
JAVA_OPT="${JAVA_OPT} -server -Xms2g -Xmx2g -Xmn1g -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m"
JAVA_OPT="${JAVA_OPT} -server -Xms2g -Xmx2g -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m"

[root@localhost rocketmq]# vi bin/runbroker.sh
JAVA_OPT="${JAVA_OPT} -server -Xms4g -Xmx4g"
JAVA_OPT="${JAVA_OPT} -XX:MaxDirectMemorySize=4g"

用户组和用户

创建专用的数据存储目录

$ mkdir -p /home/rocketmq/data/store
$ mkdir -p /home/rocketmq/logs

所有主机上，创建 rocketmq:rocketmq 用户组和用户，并进行授权：

$ groupadd rocketmq
$ useradd -g rocketmq -M -s /sbin/nologin rocketmq
$ chown -R rocketmq. /home/rocketmq/data/
$ chown -R rocketmq. /home/rocketmq/logs/
$ chown -R rocketmq. /usr/local/rocketmq/

配置集群配置文件

根据我们选择的 “多节点（集群）多副本模式-同步双写” 模式，找到对应的配置文件，比如在 /usr/local/rocketmq/conf/2m-2s-sync/ 目录下，有 broker-a.properties、broker-a-s.properties、broker-b.properties、broker-b-s.properties 四个配置文件：

配置文件与预安装集群的主机对应关系如下：

这里务必配置 storePathRootDir 相关参数，实际上启动运行时候没配置会提示错误无法配置开机自启动！

配置 broker-a.properties：

[root@rocketmq ~]# vi /usr/local/rocketmq/conf/2m-2s-sync/broker-a.properties

Name Server 开机自启动

所有主机上，配置开机启动脚本：

[root@rocketmq ~]# vi /lib/systemd/system/rocketmq-namesrv.service

脚本内容：

After=network.target

[Service]

#ExecReload=/bin/kill -s HUP $MAINPID
#ExecStop=/bin/kill -s QUIT $MAINPID
LimitNOFILE=65536
