1. 安装前的准备
1.1 安装环境
1.1.1 操作系统内核版本
[root@localhost ~]# uname -a
Linux localhost.localdomain 3.10.0-1160.el7.x86_64 #1 SMP Mon Oct 19 16:18:59 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

1.1.2 操作系统发行版本
[root@localhost ~]# cat /etc/redhat-release
CentOS Linux release 7.9.2009 (Core)

1.2 安装文件
1.2.1 安装文件下载
官网地址: http://rocketmq.apache.org/
下载地址: http://rocketmq.apache.org/dowloading/releases/
1.2.2 安装文件列表
rocketmq-all-4.9.1-bin-release.zip
2. 安装和配置
2.1 软件安装
2.1.1 安装前的检测
检测软件是否已安装
[root@localhost ~]# rpm -qa | grep rocketmq

查看运行进程
[root@localhost ~]# ps -ef | grep rocketmq
root 47876 46534 0 07:57 pts/1 00:00:00 grep rocketmq

卸载软件文件
[root@localhost ~]# rpm -e mongodb-database-tools-100.5.0-1.x86_64 –nodeps

2.1.2 安装RocketMQ
切换至软件目录;
[root@localhost ~]# cd /home/Software/RocketMQ
[root@localhost RocketMQ]# ls
rocketmq-all-4.9.1-bin-release.zip

解压缩“rocketmq-all-4.9.1-bin-release.zip”;
[root@localhost RocketMQ]# unzip rocketmq-all-4.9.1-bin-release.zip
Archive: rocketmq-all-4.9.1-bin-release.zip
creating: rocketmq-all-4.9.1-bin-release/
creating: rocketmq-all-4.9.1-bin-release/benchmark/

inflating: rocketmq-all-4.9.1-bin-release/conf/plain_acl.yml
inflating: rocketmq-all-4.9.1-bin-release/conf/logback_namesrv.xml
[root@localhost RocketMQ]# ls
rocketmq-all-4.9.1-bin-release rocketmq-all-4.9.1-bin-release.zip
[root@localhost RocketMQ]# mv rocketmq-all-4.9.1-bin-release /opt/
[root@localhost RocketMQ]# cd /opt/
[root@localhost opt]# ls
rocketmq-all-4.9.1-bin-release

启动数据库服务
由于 RocketMQ 初始化部分参数并不适用于实际项目,故先完成部分初始化配置。

2.2 软件配置
2.2.1 修改 Name Server 默认内存
[root@localhost ~]# cd /opt/rocketmq-all-4.9.1-bin-release/
[root@localhost rocketmq-all-4.9.1-bin-release]# vim ./bin/runserver.sh

# 修改前
JAVA_OPT=”${JAVA_OPT} -server -Xms4g -Xmx4g -Xmn2g -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m”

# 修改后
JAVA_OPT=”${JAVA_OPT} -server -Xms512m -Xmx512m -Xmn256m -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m”

2.2.2 修改 Broker 默认内存
[root@localhost ~]# cd /opt/rocketmq-all-4.9.1-bin-release/
[root@localhost rocketmq-all-4.9.1-bin-release]# vim ./bin/runbroker.sh

# 修改前
JAVA_OPT=”${JAVA_OPT} -server -Xms8g -Xmx8g”

# 修改后
JAVA_OPT=”${JAVA_OPT} -server -Xms512m -Xmx512m”

6. 常见问题
6.1 启动 Broker 时,打印日志提示“cannot open `/root/logs/rocketmqlogs/broker.log’ for reading: No such file or directory”
问题原因:启动 Broker 服务时,由于默认内存设置过大,造成 Broker 服务无法正常 启动,查看/%ROCKERMQ%/nohup.out 查看具体错误日志:

Java HotSpot(TM) 64-Bit Server VM warning: INFO:
os::commit_memory(0x00000005c0000000, 8589934592, 0) failed; error=’Cannot allocate
memory’ (errno=12)
#
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (mmap) failed to map 8589934592 bytes for committing
reserved memory.
# An error report file with more information is saved as:
# /home/Hehuang/SHIOT-1/SERVICE-1/rocketmq-all-4.9.1-binrelease/hs_err_pid51750.log

解决方案:修改 Broker 默认内存,具体参考 2.2.1【修改 Broker 默认内存】。

6.2 启动 Name Server 或 Broker 时,提示“[1]+ Exit 1 nohup sh bin/…”
问题原因:说明 Name Server 或 Broker 服务未正常启动。

解决方案:查看/%ROCKERMQ%/nohup.out 查看具体错误日志。
