linux(centos8):基于java13安装rocketmq-4.7.1(解决jdk不兼容的报错)

一，Rocketmq是什么？

1, RocketMQ是一个队列模型的消息中间件，具有高性能、高可靠、高实时、分布式特点

相比kafka,rocketmq的实时性更强

2,官方网站:

http://rocketmq.apache.org/

说明：刘宏缔的架构森林是一个专注架构的博客，地址：https://www.cnblogs.com/architectforest

对应的源码可以访问这里获取： https://github.com/liuhongdi/

说明：作者:刘宏缔邮箱: 371125307@qq.com

二，下载:

从官网找到下载地址后:

[root@localhost rocketmq]# pwd

/usr/local/source/rocketmq

[root@localhost rocketmq]# wget https://mirror.bit.edu.cn/apache/rocketmq/4.7.1/rocketmq-all-4.7.1-bin-release.zip

保存到源安装文件目录

三，解压:

[root@localhost rocketmq]# unzip rocketmq-all-4.7.1-bin-release.zip

移动到安装目录:

[root@localhost rocketmq]# mv rocketmq-all-4.7.1-bin-release /usr/local/soft/

四，配置rocketmq

1，配置conf文件:

[root@localhost rocketmq-all-4.7.1-bin-release]# vi conf/broker.conf

添加两行:

namesrvAddr = 127.0.0.1:9876

autoCreateTopicEnable = true

2，修改runserver.sh启动参数:

[root@localhost rocketmq-all-4.7.1-bin-release]# vi bin/runserver.sh

因为占用内存较多，需要改小，如果内存充足可以不改

原代码：

JAVA_OPT="${JAVA_OPT} -server -Xms4g -Xmx4g -Xmn2g -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m"

修改为:

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

3,修改runbroker.sh启动参数

[root@localhost rocketmq-all-4.7.1-bin-release]# vi bin/runbroker.sh

原代码：

JAVA_OPT="${JAVA_OPT} -server -Xms8g -Xmx8g -Xmn4g"

修改为:

JAVA_OPT="${JAVA_OPT} -server -Xms512m -Xmx512m -Xmn256m"

五,生成启动和关闭的脚本:

[root@localhost rocketmq-all-4.7.1-bin-release]# vi start_namesrv.sh

代码:

nohup sh bin/mqnamesrv &

[root@localhost rocketmq-all-4.7.1-bin-release]# vi stop_namesrv.sh

代码:

sh bin/mqshutdown namesrv

[root@localhost rocketmq-all-4.7.1-bin-release]# vi start_broker.sh

代码:

nohup sh bin/mqbroker -c /usr/local/soft/rocketmq-all-4.7.1-bin-release/conf/broker.conf &

[root@localhost rocketmq-all-4.7.1-bin-release]# vi stop_broker.sh

代码:

sh bin/mqshutdown broker

给脚本增加执行权限:

[root@localhost rocketmq-all-4.7.1-bin-release]# chmod +x *.sh

六，用java13启动rocketmq4.7.1时的报错:

说明：启动时会出现报错是因为rocketmq针对的jdk版本较低，有一些启动项在新版java上已删除

如果使用低版本的jdk8可以解决，如果不想降低版本则需修改启动项

1,解决启动nameserver时报错:

报错：

[root@localhost rocketmq-all-4.7.1-bin-release]# bin/mqnamesrv

Java HotSpot(TM) 64-Bit Server VM warning: Option UseConcMarkSweepGC was deprecated in version 9.0 and will likely be removed in a future release.

Unrecognized VM option 'UseCMSCompactAtFullCollection'

Error: Could not create the Java Virtual Machine.

Error: A fatal exception has occurred. Program will exit.

解决:
修改bin/runserver.sh
注释掉下面一行:

#JAVA_OPT="${JAVA_OPT} -XX:+UseConcMarkSweepGC -XX:+UseCMSCompactAtFullCollection -XX:CMSInitiatingOccupancyFraction=70 -XX:+CMSParallelRemar

kEnabled -XX:SoftRefLRUPolicyMSPerMB=0 -XX:+CMSClassUnloadingEnabled -XX:SurvivorRatio=8  -XX:-UseParNewGC"

修改为:

JAVA_OPT="${JAVA_OPT} -XX:+UseConcMarkSweepGC -XX:CMSInitiatingOccupancyFraction=70 -XX:+CMSParallelRemarkEnabled -XX:SoftRefLRUPolicyMSPerMB

=0 -XX:+CMSClassUnloadingEnabled -XX:SurvivorRatio=8 "

报错：

解决：

修改bin/runserver.sh

注释掉下面这一行

#JAVA_OPT="${JAVA_OPT} -XX:+UseGCLogFileRotation -XX:NumberOfGCLogFiles=5 -XX:GCLogFileSize=30m"

报错:

[root@localhost rocketmq-all-4.7.1-bin-release]# bin/mqnamesrv

修改为:

export CLASSPATH=${BASE_DIR}/lib/rocketmq-namesrv-4.7.1.jar:${BASE_DIR}/lib/*:${BASE_DIR}/conf:${CLASSPATH}:${CLASS_PATH}

2,启动broker时的报错

报错1

[root@localhost rocketmq-all-4.7.1-bin-release]# bin/mqbroker -c /usr/local/soft/rocketmq-all-4.7.1-bin-release/conf/broker.conf

[0.001s][warning][gc] -Xloggc is deprecated. Will use -Xlog:gc:/dev/shm/rmq_broker_gc_%p_%t.log instead.

上面两个报错的解决:

修改bin/runbroker.sh

把下面一行注释掉

#JAVA_OPT="${JAVA_OPT} -verbose:gc -Xloggc:${GC_LOG_DIR}/rmq_broker_gc_%p_%t.log -XX:+PrintGCDetails -XX:+PrintGCDateStamps -XX:+PrintGCAppli

cationStoppedTime -XX:+PrintAdaptiveSizePolicy”

替换为:

JAVA_OPT="${JAVA_OPT} -verbose:gc -Xloggc:${GC_LOG_DIR}/rmq_broker_gc_%p_%t.log -XX:+PrintGCDetails"

报错：

[root@localhost rocketmq-all-4.7.1-bin-release]# bin/mqbroker -c /usr/local/soft/rocketmq-all-4.7.1-bin-release/conf/broker.conf

七，启动rocketmq

先启动namesrv

[root@localhost rocketmq-all-4.7.1-bin-release]# ./start_namesrv.sh

[root@localhost rocketmq-all-4.7.1-bin-release]# nohup: 把输出追加到 'nohup.out'

再启动broker

[root@localhost rocketmq-all-4.7.1-bin-release]# ./start_broker.sh

[root@localhost rocketmq-all-4.7.1-bin-release]# nohup: 把输出追加到 'nohup.out'

八，测试安装效果:

1,通过jps查看进程:

[root@localhost rocketmq-all-4.7.1-bin-release]# /usr/local/soft/jdk-13/bin/jps

66026 BrokerStartup

65610 NamesrvStartup

66573 Jps

2,查看rocketmq生成的日志:

[root@localhost rocketmq-all-4.7.1-bin-release]# tail -f ~/logs/rocketmqlogs/broker.log

2020-09-11 15:27:55 INFO brokerOutApi_thread_3 - register broker[0]to name server 127.0.0.1:9876 OK

3,手动用命令创建topic

[root@localhost rocketmq-all-4.7.1-bin-release]# ./bin/mqadmin updateTopic -t laoliutest -b localhost:10911 -n localhost:9876

可以看到我们已创建的laoliutest这个topic

九，查看java的版本:

[root@localhost rocketmq-all-4.7.1-bin-release]# java --version

java 13 2019-09-17

Java(TM) SE Runtime Environment (build 13+33)

十，查看linux的版本:

[root@localhost java]$ cat /etc/redhat-release

CentOS Linux release 8.2.2004 (Core)
