deemopen / zkui Goto Github PK

We plan to deploy this in our QA environment and were looking for options to disable any authentication.

import file content is

/=测试名字=测试值hahaha

Change Import.java

uploadFileName = item.getName();
//this cause error
//sbFile.append(item.getString()); 

//this can work well
sbFile.append(item.getString("UTF-8"));

zk集群有5台，挂掉了一台，zkui整个挂掉了，请问怎么解决

Hi,

i cant insert propertys with special chars like "ß" or "é". Zookeeper it self allow these chars.

Propertyname: test

When zkui is accessed through a proxy, zkui redirects to http: instead of https:/

Monitor will throw NumberFormatException when zkServer contains some node path, such as
zkServer=localhost:2181/parent/child
I modify this codes as following , and it works well.

Hi, when I import the project,I found the build error,like:
Plugin execution not covered by lifecycle configuration: org.javalite:activejdbc-instrumentation:1.4.1:instrument (execution: default, phase: process- classes)
Error occurs in pom.xml:
<plugin> <groupId>org.javalite</groupId> <artifactId>activejdbc-instrumentation</artifactId> <version>1.4.1</version> <executions> <execution> <phase>process-classes</phase> <goals> <goal>instrument</goal> </goals> </execution> </executions> </plugin>

Could you give me some tips to fix it?

Thank you for your help.

Step 4 : ADD zkui-*.jar /var/app/zkui.jar
No source files were specified

zkui-*.jar 在那个地方？

Haven't seen zookeeper userName and password config properties in the config.cfg，can you support it,thank you

修改WEB不要密码就能访问的功能
cd ~/App/zkui/src/main/java/com/deem/zkui/filter/
cp AuthFilter.java AuthFilter.java.bak
vi AuthFilter.java
把
public void doFilter
这个函数改成
@OverRide
public void doFilter(ServletRequest req, ServletResponse res, FilterChain fc) throws IOException, ServletException {
HttpServletRequest request = (HttpServletRequest) req;
HttpServletResponse response = (HttpServletResponse) res;

    fc.doFilter(req, res);
}

保存退出

pkill -9 -f "zkui-2.0-SNAPSHOT-jar-with-dependencies.jar"
cd ~/App/zkui/
mvn clean install

when login then zkui error

Have you encountered this error before?

Hi,

I installed Zookeeper UI on AWS and I have a problem. The Monitor web page is empty, it shows the IPs of all servers but not the servers status.

I investigated a little and I think I found the problem. I noticed that the "status" and "envi" commands are sent trough netcat. The problem is that it's using the -q option which is not supported on RedHat based distributions.

E.g.
/bin/sh -c 'echo stat' | nc -q5 127.0.0.1 2181
returns
nc: invalid option -- 'q'

The -q option should be used only when supported.

New to git, but I cloned this and do not see the file zkui-2.0-SNAPSHOT-jar-with-dependencies.jar that is supposed to run it...?

thanks

How to add the ACL authentication

配置如下：不用通过admin登陆。
ldapAuth=true
ldapDomain=voice.com
#ldap authentication url. Ignore if using file based authentication.
ldapUrl=ldap://Win2008.voice.com:389/dc=voice,dc=com
#Specific roles for ldap authenticated users. Ignore if using file based authentication.
ldapRoleSet={"users": [{ "username":"voice\admin" , "role": "ADMIN" }]}

Powered by Jetty://

I can not commit or push code, so, just point out what the problem is and how to fix it.

The gui is very slow while we do any action on it, that's because every time it start up a new connection to zk server.

The problem exists in the com.deem.zkui.utils.ServletUtil.java's getZookeeper function.

It did not wait for the zk to establish connection to zk server.
'''
zk = ZooKeeperUtil.INSTANCE.createZKConnection(zkServer, zkSessionTimeout);
ZooKeeperUtil.INSTANCE.setDefaultAcl(globalProps.getProperty("defaultAcl"));
if (zk.getState() != ZooKeeper.States.CONNECTED) {
session.setAttribute("zk", null);
} else {
session.setAttribute("zk", zk);
}
'''

fix, add a sleep before check the connection status:
'''
zk = ZooKeeperUtil.INSTANCE.createZKConnection(zkServer, zkSessionTimeout);
ZooKeeperUtil.INSTANCE.setDefaultAcl(globalProps.getProperty("defaultAcl"));
while (zk.getState() == ZooKeeper.States.CONNECTING){
Thread.sleep(100);
}
if (zk.getState() != ZooKeeper.States.CONNECTED) {
session.setAttribute("zk", null);
} else {
session.setAttribute("zk", zk);
}

Hola! @sguclu has created a ZenHub account for the DeemOpen organization. ZenHub is the leading team collaboration and project management solution built for GitHub.

How do I use ZenHub?

To get set up with ZenHub, all you have to do is download the browser extension and log in with your GitHub account. Once you do, you’ll get access to ZenHub’s complete feature-set immediately.

What can ZenHub do?

ZenHub adds a series of enhancements directly inside the GitHub UI:

• Real-time, customizable task boards for GitHub issues;
• Burndown charts, estimates, and velocity tracking based on GitHub Milestones;
• Personal to-do lists and task prioritization;
• “+1” button for GitHub issues and comments;
• Drag-and-drop file sharing;
• Time-saving shortcuts like a quick repo switcher.

Add ZenHub to GitHub

Still curious? See more ZenHub features or read user reviews. This issue was written by your friendly ZenHub bot, posted by request from @sguclu.

I like your program the only issue is that the Value TEXTAREA is too small. I am using the Value as not just a single-line entry but to store an entire file (multi-line). It would be nice if the modal dialog was larger in general and the value area was larger.

https://github.com/medined/docker-zookeeper - Thanks for sharing this web application. I wrapped it with a Docker image and a script to start a three-node ensemble.

Could you please upload the image to docker hub and provide the install guide for docker in readme?

The pattern for building the value of Context.SECURITY_PRINCIPAL is defined to be domain\user.
This is not generally correct.

The "Context.SECURITY_PRINCIPAL" should be the DN of the user. The definition of the mapping from
the username provided on the login screen to the DN should be freely configurable, as the DN can be virtually anything.

Fix: Provide a property "userDNPattern"
(maybe like spring ldap does via "uid={0},ou=whatiwant", where {0} is replaced by the username from the login screen)
Use this inside the class "LdapAuth" instead of the hard wired "domain\user".

Hint: Newly added properties in config.cfg should have a reasonable default value in the java-code if they
are not found in config.cfg! Some container builds grab the latest version from here, but provide their own config file. They will fail if they have missing values in their config otherwise.

Hi ,
Am new to zookeeper Ui , am trying to just install it my Mac system , I followed the steps which are mentioned but it shows "address already in use" again and again .
I tried changing the port number , still not working .
I verified using netsat command , no other process is running with 9090 .
Has anyone faced this issue ?

First of all--great project! Just forked this and am gonna contribute.

First issue--appconfig/hosts does not get created upon initial zkui and does not update upon subsequent startups. Should do both.

I want install zkui on centos 7.1, But I have this error.

Try to view a node that has

aclVersion = 0
ephemeralOwner = 0x0
dataLength = 219
numChildren = 312763

failed with

I need to run the application on 127.0.0.1:9090 but I do not see the necessary options in the config file, and also in the source code (eg, serverHost = 127.0.0.1). Please tell me how to do it and is it possible?

when node has ACL setting, listNodeEntries function will be failure. Could please add ACL setting per node and addAuthInfo calling to fix this.

Hello,
I am getting the atatched exception while bringing up the zkui.

Please advise what could be wrong.

Regards,

I think docker/bootstrap.sh is written in Windows.
I build it then run it:

docker build -t zkui:2.0 .
docker-compose up -d zkui

then run it, it report errors. /bin/sh^M: bad interpreter: No such file or directory
this is my docker-compose.yaml

version: "3"
services:
  zookeeper:
    image: zookeeper:3.4.13
    restart: always
    ports:
      - "2181:2181"
  zkui:
    image: zkui:2.0
    ports:
      - "9090:9090"
    environment:
      - ZK_SERVER=zookeeper:2181
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
    depends_on:
      - zookeeper

I have solve this problem, I rewrote bootstrap.sh in Linux.

running by docker command:

docker run -d --name zkui -p 9090:9090 -e ZKUI_ZK_SERVER=127.0.0.1:2181 qnib/zkui

After running $ nvm clean install and $ cp config.cfg target/ and $ java -jar zkui-2.0-SNAPSHOT-jar-with-dependencies.jar, the browser shows:

Hi,

Just test it, and have a kerberos based issue:
KeeperErrorCode = NoAuth for /hadoop-ha

Is it possible to filter zk spaces out? i don't like that anyone could tinker around in our HA config.

thanks,

nginx is configured as,

        location /zkui {
                proxy_pass http://localhost:8090;
        }

But zkui will reference from /. Is there a config I can force it referencing to /zkui?

问题描述:
在 mysql Ver 15.1 Distrib 10.1.28-MariaDB 上执行V1__Core.sql 正常.
在 mysql Ver 14.14 Distrib 5.7.18 上执行报All parts of a PRIMARY KEY must be NOT NULL; if you need NULL in a key, use UNIQUE instead. (需要将堆栈打印到日志才能看到, 否则可能看到Error trying to migrate db! Not severe hence proceeding forward.)

解决方法:
修改文件V1__Core.sql ,
将 id bigint default null auto_increment primary key 改为 id bigint not null auto_increment primary key 即可.
重新启动之前把库中表schema_version删掉, 以免出现其它问题.
