问题
由于甲方预算有限，需要手动在linux上面安装RocketMQ单机版，（嗯，单机版，你没听错）
步骤
添加用户和用户组
sudo useradd --system --home /usr/local/rocketmq --shell /sbin/nologin --comment "rocketmq user" --user-group rocketmq
手动安装RocketMQ二进制包
# 下载二进制安装包
wget https://dist.apache.org/repos/dist/release/rocketmq/5.2.0/rocketmq-all-5.2.0-bin-release.zip
# 解压到/usr/local/ 目录下面
sudo unzip -d /usr/local/ rocketmq-all-5.2.0-bin-release.zip
# 修改解压文件夹名称为rocketmq
sudo mv /usr/local/rocketmq-all-5.2.0-bin-release/ /usr/local/rocketmq/
# 修改安装目录文件夹与文件权限
# 授权文件夹拥有者为rocketmq用户
sudo chown -R rocketmq /usr/local/rocketmq
# 授权文件夹用户组为rocketmq
sudo chgrp -R rocketmq /usr/local/rocketmq
SysV 配置文件
新建nameserver配置文件：
sudo vim /usr/lib/systemd/system/rocketmq.service
内容：
[Unit]
Description=RocketMQ 5.2.0 - nameserver
After=network.target
[Service]
User=rocketmq
Group=rocketmq
Type=simple
ExecStart=/usr/local/rocketmq/bin/mqnamesrv
ExecStop=/usr/local/rocketmq/bin/mqshutdown namesrv
[Install]
WantedBy=multi-user.target
新建Broker+Proxy配置文件：
sudo vim /usr/lib/systemd/system/mqbroker.service
内容：
[Unit]
Description=RocketMQ 5.2.0 - Broker+Proxy
After=network.target
[Service]
User=rocketmq
Group=rocketmq
Type=simple
ExecStart=/usr/local/rocketmq/bin/mqbroker -n localhost:9876 --enable-proxy
ExecStop=/usr/local/rocketmq/bin/mqshutdown broker
[Install]
WantedBy=multi-user.target
重载SysV配置：
sudo systemctl daemon-reload
安装Java
sudo dnf install java-17-amazon-corretto
启动nameserver服务
sudo systemctl start rocketmq.service
查看启动状态：
sudo systemctl status rocketmq.service
启动状态如下：

启动Broker+Proxy服务
sudo systemctl start mqbroker.service
总结
生产环境千万别这样玩，这是个单机版。主要是演示SysV的配置。
