RocketMQ集群安装 2主2从 console

安装zip和maven
yum install -y unzip zip

wget http://repos.fedorapeople.org/repos/dchen/apache-maven/epel-apache-maven.repo -O /etc/yum.repos.d/epel-apache-maven.repo
yum -y install apache-maven

cd /opt/rocketmq
mvn -Prelease-all -DskipTests clean install -U

wget -P /opt/downloads http://mirrors.tuna.tsinghua.edu.cn/apache/rocketmq/4.5.0/rocketmq-all-4.5.0-bin-release.zip
unzip /opt/downloads/rocketmq-all-4.5.0-bin-release.zip -d /opt
mv /opt/rocketmq-all-4.5.0-bin-release /opt/rocketmq

jdk9以上版本，官方脚本报错比较多，参照https://www.cnblogs.com/wintersoft/p/10881601.html

强烈建议jdk版本不要超过8，否则后面容易出现各种奇葩问题。

备份防止意外
cp -r /opt/rocketmq/conf/ /opt/rocketmq/conf.default/

mkdir /opt/rocketmqs/
cp -a /opt/rocketmq/* /opt/rocketmqs

参照
vim /opt/rocketmq/conf/2m-2s-sync/broker-a.properties
修改
vim /opt/rocketmq/conf/broker.properties

配置文件后面加入
listenPort=10911
namesrvAddr=192.168.1.101:9876;192.168.1.102:9876
brokerIP1=192.168.1.102
storePathRootDir=/opt/rocketmq/store
storePathCommitLog=/opt/rocketmq/store/commitlog
storePathConsumeQueue=/opt/rocketmq/store/consumequeue
storePathIndex=/opt/rocketmq/store/index
storeCheckpoint=/opt/rocketmq/store/checkpoint
指定ip否则多网卡会报connect to XXXX:10909 failed
Rocket默认开启10909端口为vip通道
另一台服务器a换成b

参照
vim /opt/rocketmqs/conf/2m-2s-sync/broker-a-s.properties
修改
vim /opt/rocketmq/conf/broker.properties

配置文件后面加入
listenPort=10912
namesrvAddr=192.168.1.101:9876;192.168.1.102:9876
brokerIP1=192.168.1.102
storePathRootDir=/opt/rocketmqs/store
storePathCommitLog=/opt/rocketmqs/store/commitlog
storePathConsumeQueue=/opt/rocketmqs/store/consumequeue
storePathIndex=/opt/rocketmqs/store/index
storeCheckpoint=/opt/rocketmqs/store/checkpoint

另一台服务器a换成b

注意坑：默认并不会读取conf目录的broker.conf

安装nameserver守护进程
vim /lib/systemd/system/rocketmq-nameserver.service

[Unit]
Description=rocketmq-nameserver
After=syslog.target network.target remote-fs.target nss-lookup.target

[Service]
Type=simple
ExecStart=/bin/sh /opt/rocketmq/bin/mqnamesrv
ExecStop=/bin/sh /opt/rocketmq/bin/mqshutdown namesrv
Restart=always
PrivateTmp=true

[Install]
WantedBy=multi-user.target

权限
chmod 777 /lib/systemd/system/rocketmq-nameserver.service

systemctl enable rocketmq-nameserver.service
systemctl daemon-reload

运行
systemctl start rocketmq-nameserver.service
默认端口9876

安装broker-master守护进程
vim /lib/systemd/system/rocketmq-broker.service

[Unit]
Description=rocketmq-broker-master
After=syslog.target network.target remote-fs.target nss-lookup.target

[Service]
Type=simple
ExecStart=/bin/sh /opt/rocketmq/bin/mqbroker -c /opt/rocketmq/conf/broker.properties
ExecStop=/bin/sh /opt/rocketmq/bin/mqshutdown broker
Restart=always
PrivateTmp=true

[Install]
WantedBy=multi-user.target

权限
chmod 777 /lib/systemd/system/rocketmq-broker.service

systemctl enable rocketmq-broker.service
systemctl daemon-reload

运行
systemctl start rocketmq-broker.service

安装broker-slave守护进程
vim /lib/systemd/system/rocketmq-broker-s.service

[Unit]
Description=rocketmq-broker-slave
After=syslog.target network.target remote-fs.target nss-lookup.target

[Service]
Type=simple
ExecStart=/bin/sh /opt/rocketmqs/bin/mqbroker -c /opt/rocketmqs/conf/broker.properties
ExecStop=/bin/sh /opt/rocketmqs/bin/mqshutdown broker
Restart=always
PrivateTmp=true

[Install]
WantedBy=multi-user.target

权限
chmod 777 /lib/systemd/system/rocketmq-broker-s.service

systemctl enable rocketmq-broker-s.service
systemctl daemon-reload

运行
systemctl start rocketmq-broker-s.service

安装rocketmq-console
下载源码https://github.com/apache/rocketmq-externals
打包mvn clean package -Dmaven.test.skip=true得到rocketmq-console-ng-1.0.1.jar

复制到/opt/rocketmq-console

查找java文件软连接路径（略）
ls /usr/bin/java -al 得到/etc/alternatives/java
ls /etc/alternatives/java -al
真实路径为/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.212.b04-0.el7_6.x86_64/jre/bin/java

vim /lib/systemd/system/rocketmq-console.service

[Unit]
Description=rocketmq-console
After=syslog.target network.target remote-fs.target nss-lookup.target

[Service]
Type=simple
ExecStart=/usr/bin/java -jar /opt/rocketmq-console/rocketmq-console-ng-1.0.1.jar --server.port=9875 --rocketmq.config.namesrvAddr=192.168.1.101:9876;192.168.1.101:9876
Restart=always
PrivateTmp=true

[Install]
WantedBy=multi-user.target

权限
chmod 777 /lib/systemd/system/rocketmq-console.service

systemctl enable rocketmq-console.service
systemctl daemon-reload

运行
systemctl start rocketmq-console.service
