RocketMQ|CentOS 7使用RocketMQ mqadmin命令工具报错 updateTopic|HmacSHA1|rocketMQ

问题描述
我在CentOS 7上安装好RocketMQ之后，使用mqadmin创建topic，命令如下：

./mqadmin updateTopic -n 192.168.77.129:9876 -c DefaultCluster -t test

然后报错信息如下：

org.apache.rocketmq.tools.command.SubCommandException: UpdateTopicSubCommand command failed at org.apache.rocketmq.tools.command.topic.UpdateTopicSubCommand.execute(UpdateTopicSubCommand.java:181) at org.apache.rocketmq.tools.command.MQAdminStartup.main0(MQAdminStartup.java:135) at org.apache.rocketmq.tools.command.MQAdminStartup.main(MQAdminStartup.java:86) Caused by: org.apache.rocketmq.acl.common.AclException: [10015:signature-failed] unable to calculate a request signature. error=[10015:signature-failed] unable to calculate a request signature. error=Algorithm HmacSHA1 not available at org.apache.rocketmq.acl.common.AclSigner.signAndBase64Encode(AclSigner.java:84) at org.apache.rocketmq.acl.common.AclSigner.calSignature(AclSigner.java:73) at org.apache.rocketmq.acl.common.AclSigner.calSignature(AclSigner.java:68) at org.apache.rocketmq.acl.common.AclUtils.calSignature(AclUtils.java:58) at org.apache.rocketmq.acl.common.AclClientRPCHook.doBeforeRequest(AclClientRPCHook.java:44) at org.apache.rocketmq.remoting.netty.NettyRemotingAbstract.doBeforeRpcHooks(NettyRemotingAbstract.java:172) at org.apache.rocketmq.remoting.netty.NettyRemotingClient.invokeSync(NettyRemotingClient.java:370) at org.apache.rocketmq.client.impl.MQClientAPIImpl.getBrokerClusterInfo(MQClientAPIImpl.java:1180) at org.apache.rocketmq.tools.admin.DefaultMQAdminExtImpl.examineBrokerClusterInfo(DefaultMQAdminExtImpl.java:275) at org.apache.rocketmq.tools.admin.DefaultMQAdminExt.examineBrokerClusterInfo(DefaultMQAdminExt.java:222) at org.apache.rocketmq.tools.command.CommandUtil.fetchMasterAddrByClusterName(CommandUtil.java:83) at org.apache.rocketmq.tools.command.topic.UpdateTopicSubCommand.execute(UpdateTopicSubCommand.java:154) ... 2 more Caused by: org.apache.rocketmq.acl.common.AclException: [10015:signature-failed] unable to calculate a request signature. error=Algorithm HmacSHA1 not available at org.apache.rocketmq.acl.common.AclSigner.sign(AclSigner.java:63) at org.apache.rocketmq.acl.common.AclSigner.signAndBase64Encode(AclSigner.java:79) ... 13 more Caused by: java.security.NoSuchAlgorithmException: Algorithm HmacSHA1 not available at javax.crypto.Mac.getInstance(Mac.java:181) at org.apache.rocketmq.acl.common.AclSigner.sign(AclSigner.java:57) ... 14 more

原因及解决方案
原因是安装CentOS 7的时候，系统自带的是jre，并没有安装jdk。通过javac命令可以发现：

[root@localhost local]# javac bash: javac: command not found... Similar command is: 'java' [root@localhost local]# javac -version bash: javac: command not found... Similar command is: 'java'

因此我们重新安装一下jdk就好了，安装步骤如下：
1、yum list java-*

[root@localhost local]# yum list java-* Loaded plugins: fastestmirror, langpacks Loading mirror speeds from cached hostfile * base: mirrors.njupt.edu.cn * extras: centos.ustc.edu.cn * updates: mirrors.njupt.edu.cn Installed Packages java-1.7.0-openjdk.x86_641:1.7.0.191-2.6.15.5.el7@anaconda java-1.7.0-openjdk-headless.x86_641:1.7.0.191-2.6.15.5.el7@anaconda java-1.8.0-openjdk.x86_641:1.8.0.181-7.b13.el7@anaconda java-1.8.0-openjdk-headless.x86_641:1.8.0.181-7.b13.el7@anaconda Available Packages java-1.6.0-openjdk.x86_641:1.6.0.41-1.13.13.1.el7_3base java-1.6.0-openjdk-demo.x86_641:1.6.0.41-1.13.13.1.el7_3base java-1.6.0-openjdk-devel.x86_641:1.6.0.41-1.13.13.1.el7_3base

2、安装相应版本的jdk：yum install java-1.8.0-openjdk-devel.x86_64

[root@localhost local]# yum install java-1.8.0-openjdk-devel.x86_64 Loaded plugins: fastestmirror, langpacks Loading mirror speeds from cached hostfile * base: mirrors.njupt.edu.cn * extras: centos.ustc.edu.cn * updates: mirrors.njupt.edu.cn Resolving Dependencies --> Running transaction check ---> Package java-1.8.0-openjdk-devel.x86_64 1:1.8.0.222.b10-0.el7_6 will be installed --> Processing Dependency: java-1.8.0-openjdk(x86-64) = 1:1.8.0.222.b10-0.el7_6 for package: 1:java-1.8.0-openjdk-devel-1.8.0.222.b10-0.el7_6.x86_64 --> Running transaction check ---> Package java-1.8.0-openjdk.x86_64 1:1.8.0.181-7.b13.el7 will be updated ---> Package java-1.8.0-openjdk.x86_64 1:1.8.0.222.b10-0.el7_6 will be an update --> Processing Dependency: java-1.8.0-openjdk-headless(x86-64) = 1:1.8.0.222.b10-0.el7_6 for package: 1:java-1.8.0-openjdk-1.8.0.222.b10-0.el7_6.x86_64 --> Running transaction check ---> Package java-1.8.0-openjdk-headless.x86_64 1:1.8.0.181-7.b13.el7 will be updated ---> Package java-1.8.0-openjdk-headless.x86_64 1:1.8.0.222.b10-0.el7_6 will be an update --> Finished Dependency ResolutionDependencies Resolved=================================================================================================================================================================================================================== PackageArchVersionRepositorySize =================================================================================================================================================================================================================== Installing: java-1.8.0-openjdk-develx86_641:1.8.0.222.b10-0.el7_6updates9.8 M Updating for dependencies: java-1.8.0-openjdkx86_641:1.8.0.222.b10-0.el7_6updates274 k java-1.8.0-openjdk-headlessx86_641:1.8.0.222.b10-0.el7_6updates32 MTransaction Summary =================================================================================================================================================================================================================== Install1 Package Upgrade( 2 Dependent packages)Total size: 42 M Total download size: 9.8 M Is this ok [y/d/N]: y Downloading packages: java-1.8.0-openjdk-devel-1.8.0.222.b10-0.el7_6.x86_64.rpm| 9.8 MB00:00:21 Running transaction check Running transaction test Transaction test succeeded Running transaction Updating: 1:java-1.8.0-openjdk-headless-1.8.0.222.b10-0.el7_6.x86_641/5 warning: /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.222.b10-0.el7_6.x86_64/jre/lib/security/java.security created as /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.222.b10-0.el7_6.x86_64/jre/lib/security/java.security.rpmnew restored /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.222.b10-0.el7_6.x86_64/jre/lib/security/java.security.rpmnew to /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.222.b10-0.el7_6.x86_64/jre/lib/security/java.security Updating: 1:java-1.8.0-openjdk-1.8.0.222.b10-0.el7_6.x86_642/5 Installing : 1:java-1.8.0-openjdk-devel-1.8.0.222.b10-0.el7_6.x86_643/5 Cleanup: 1:java-1.8.0-openjdk-1.8.0.181-7.b13.el7.x86_644/5 Cleanup: 1:java-1.8.0-openjdk-headless-1.8.0.181-7.b13.el7.x86_645/5 Verifying: 1:java-1.8.0-openjdk-headless-1.8.0.222.b10-0.el7_6.x86_641/5 Verifying: 1:java-1.8.0-openjdk-1.8.0.222.b10-0.el7_6.x86_642/5 Verifying: 1:java-1.8.0-openjdk-devel-1.8.0.222.b10-0.el7_6.x86_643/5 Verifying: 1:java-1.8.0-openjdk-headless-1.8.0.181-7.b13.el7.x86_644/5 Verifying: 1:java-1.8.0-openjdk-1.8.0.181-7.b13.el7.x86_645/5 Installed: java-1.8.0-openjdk-devel.x86_64 1:1.8.0.222.b10-0.el7_6Dependency Updated: java-1.8.0-openjdk.x86_64 1:1.8.0.222.b10-0.el7_6java-1.8.0-openjdk-headless.x86_64 1:1.8.0.222.b10-0.el7_6Complete!

3、vim /etc/profile
添加环境变量：

export JAVA_HOME=/usr/lib/jvm/javaexport CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JAVA_HOME/jre/lib/rt.jarexport PATH=$PATH:$JAVA_HOME/bin

4、source /etc/profile
这样修改就生效了，通过javac命令可以看到：

[root@localhost bin]# javac Usage: javac where possible options include: -gGenerate all debugging info -g:noneGenerate no debugging info -g:{lines,vars,source}Generate only some debugging info -nowarnGenerate no warnings -verboseOutput messages about what the compiler is doing -deprecationOutput source locations where deprecated APIs are used -classpath Specify where to find user class files and annotation processors -cp Specify where to find user class files and annotation processors -sourcepath Specify where to find input source files -bootclasspath Override location of bootstrap class files -extdirs Override location of installed extensions -endorseddirs Override location of endorsed standards path -proc:{none,only}Control whether annotation processing and/or compilation is done. -processor [,,...] Names of the annotation processors to run; bypasses default discovery process -processorpath Specify where to find annotation processors -parametersGenerate metadata for reflection on method parameters -d Specify where to place generated class files -s Specify where to place generated source files -h Specify where to place generated native header files -implicit:{none,class}Specify whether or not to generate class files for implicitly referenced files -encoding Specify character encoding used by source files -source Provide source compatibility with specified release -target Generate class files for specific VM version -profile Check that API used is available in the specified profile -versionVersion information -helpPrint a synopsis of standard options -Akey[=value]Options to pass to annotation processors -XPrint a synopsis of nonstandard options -JPass directly to the runtime system -WerrorTerminate compilation if warnings occur @Read options and filenames from file

echo $PATH也可以看到：

root@localhost bin]# echo $PATH /usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/bin:/sbin:/bin:/usr/local/apache-maven-3.6.1/bin:/home/gameloft9/.local/bin:/home/gameloft9/bin:/usr/lib/jvm/java/bin:/usr/local/apache-maven-3.6.1/bin [root@localhost bin]#

然后我们再运行创建topic的命令：

[gameloft9@localhost bin]$ ./mqadmin updateTopic -n 192.168.77.129:9876 -c DefaultCluster -t test OpenJDK 64-Bit Server VM warning: ignoring option PermSize=128m; support was removed in 8.0 OpenJDK 64-Bit Server VM warning: ignoring option MaxPermSize=128m; support was removed in 8.0 create topic to 192.168.77.129:10911 success.
