Kill command not working on java.net.BindException: Address already in use error

问题

以下是您提供的内容的翻译：

没有其他类似的帖子能解决我的问题。

为Apache Nifi生成的用户名和密码无法使用。

我正在按照这些说明进行操作。

我尝试运行tail -f nifi-app.log命令来排除问题。

并获得以下结果...

引起: java.net.BindException: 地址已被使用

2023-05-10 14:22:54,303 INFO [Thread-0] org.apache.nifi.NiFi应用程序服务器已启动关闭

我尝试使用以下命令检查端口sudo lsof -i :8443

并获得以下响应...

COMMAND   PID USER   FD   TYPE             DEVICE SIZE/OFF NODE NAME
java    71776 user 3146u  IPv4 0x9a0863600c7cb941      0t0  TCP localhost:pcsync-https (LISTEN)

所以，我使用kill 71776杀死了该进程。

然后，我再次使用bin/nifi.sh start启动了Nifi

并再次运行了tail -f nifi-app.log命令，结果如下...

2023-05-10 14:57:09,939 INFO [main] o.e.jetty.server.handler.ContextHandler 已启动o.e.j.w.WebAppContext@ff0e6d4{/nifi-jolt-transform-json-ui-1.21.0,/nifi-jolt-transform-json-ui-1.21.0,file:///Users/user/nifi-1.21.0/work/jetty/nifi-jolt-transform-json-ui-1.21.0.war/webapp/,AVAILABLE}{./work/nar/extensions/nifi-standard-nar-1.21.0.nar-unpacked/NAR-INF/bundled-dependencies/nifi-jolt-transform-json-ui-1.21.0.war}

None of the other similar posts to this issue fix my problem.

The generated username and password for Apache Nifi doesn't work.

Kill命令在java.net.BindException: Address already in use错误上无法工作。

I'm following these instructions.

Kill命令在java.net.BindException: Address already in use错误上无法工作。

I tried running the tail -f nifi-app.log command to troubleshoot the issue.

And got the following results...

Caused by: java.net.BindException: Address already in use

2023-05-10 14:22:54,303 INFO [Thread-0] org.apache.nifi.NiFi Application Server shutdown started

I tried checking the port with the following command sudo lsof -i :8443

and got the following response,,,

COMMAND   PID USER   FD   TYPE             DEVICE SIZE/OFF NODE NAME
java    71776 user 3146u  IPv4 0x9a0863600c7cb941      0t0  TCP localhost:pcsync-https (LISTEN)

So, I killed the process using kill 71776

I started Nifi again using bin/nifi.sh start

and again ran the command tail -f nifi-app.log

which resulted in the following...

It appears to be the same error as before I killed the process. Any help is appreciated.

I went into the nifi.properties file located in the conf folder.
我进入了位于conf文件夹中的nifi.properties文件。

I changed the following property from 8443 to 8442 (I chose 8442 arbitrarily hoping since it was close to 8443 that made it a good port candidate so you may want to choose a different one)
我将以下属性从8443更改为8442（我随意选择了8442，希望因为它接近8443，所以它是一个良好的端口候选项，所以您可以选择一个不同的端口）

nifi.web.https.port=8442

Then, I navigated to the login-identity-providers.xml file located in the same conf folder.
然后，我导航到位于同一conf文件夹中的login-identity-providers.xml文件。

I removed the default username and password that were in the file so that it looks like it does below.
我删除了文件中的默认用户名和密码，使其看起来如下所示。

single-user-provider
org.apache.nifi.authentication.single.user.SingleUserLoginIdentityProvider

Then, I went back to the terminal, navigated to the bin directory and ran the following command...
然后，我回到终端，导航到bin目录，并运行了以下命令...

./nifi.sh restart

It spit out a ton of code but if you use ctrl + F and search for the word "generated" (without quotes) you should see a generated username and password.
它会输出大量代码，但如果您使用Ctrl + F搜索词"generated"（不带引号），您应该会看到生成的用户名和密码。

Finally, I navigated to https://127.0.0.1:8442/nifi/ and entered the generated username and password and eureka it seems to be working!
最后，我导航到https://127.0.0.1:8442/nifi/，输入生成的用户名和密码，咦，它似乎在工作！

英文:

Well I seemed to have figured it out with some help from some other articles.

I went into the nifi.properties file located in the conf folder.

I changed the following property from 8443 to 8442 (I chose 8442 arbitrarily hoping since it was close to 8443 that made it a good port candidate so you may want to choose a different one)

nifi.web.https.port=8442

Then, I navigated to the login-identity-providers.xml file located in the same conf folder.

I removed the default username and password that were in the file so that it looks like it does below.

<provider>
<identifier>single-user-provider</identifier>
<class>org.apache.nifi.authentication.single.user.SingleUserLoginIdentityProvider</class>
<property name="Username"></property>
<property name="Password"></property>
</provider>

Then, I went back to the terminal, navigated to the bin directory and ran the following command...

./nifi.sh restart

It spit out a ton of code but if you use ctrl + F and search for the word "generated" (without quotes) you should see a generated username and password.

Finally, I navigated to https://127.0.0.1:8442/nifi/ and entered the generated username and password and eureka it seems to be working!

Hopefully nothing important was using port 8442!
