zkui安装、部署，用于管理zookeeper集群_zkud

环境：

centos7、zkui2.0、zookeeper 3.5.8

一、拉取zkui项目

  1.升级安装git

yum  -y install git

  2.拉取项目

git clone https://github.com/DeemOpen/zkui.git

 二、配置zkui jar包

  1.maven编译源码

cd zkui/
 
mvn clean install

  2.使用生成的jar包

     zkui-2.0-SNAPSHOT-jar-with-dependencies.jar

  3.编辑配置文件

cd zkui
 
vim config.cfg

#Server Port
serverPort=9090
#Comma seperated list of all the zookeeper servers
zkServer=localhost:2181,localhost:2181
#Http path of the repository. Ignore if you dont intent to upload files from repository.
scmRepo=xxx.xxx.xx.xx:2181,xxx.xxx.xx.xx:2182,xxx.xxx.xx.xx:2183
#Path appended to the repo url. Ignore if you dont intent to upload files from repository.
scmRepoPath=//appconfig.txt
#if set to true then userSet is used for authentication, else ldap authentication is used.
ldapAuth=false
ldapDomain=mycompany,mydomain
#ldap authentication url. Ignore if using file based authentication.
ldapUrl=ldap://<ldap_host>:<ldap_port>/dc=mycom,dc=com
#Specific roles for ldap authenticated users. Ignore if using file based authentication.
ldapRoleSet={"users": [{ "username":"domain\\user1" , "role": "ADMIN" }]}
userSet = {"users": [{ "username":"admin" , "password":"manager","role": "ADMIN" },{ "username":"appconfig" , "password":"appconfig","role": "USER" }]}
#Set to prod in production and dev in local. Setting to dev will clear history each time.
env=prod
jdbcClass=org.h2.Driver
jdbcUrl=jdbc:h2:zkui
jdbcUser=root
jdbcPwd=manager
#If you want to use mysql db to store history then comment the h2 db section.
#jdbcClass=com.mysql.jdbc.Driver
#jdbcUrl=jdbc:mysql://localhost:3306/zkui
#jdbcUser=root
#jdbcPwd=manager
loginMessage=Please login using admin/manager or appconfig/appconfig.
#session timeout 5 mins/300 secs.
sessionTimeout=300
#Default 5 seconds to keep short lived zk sessions. If you have large data then the read will take more than 30 seconds so increase this accordingly. 
#A bigger zkSessionTimeout means the connection will be held longer and resource consumption will be high.
zkSessionTimeout=5
#Block PWD exposure over rest call.
blockPwdOverRest=false
#ignore rest of the props below if https=false.
https=false
keystoreFile=/home/user/keystore.jks
keystorePwd=password
keystoreManagerPwd=password
# The default ACL to use for all creation of nodes. If left blank, then all nodes will be universally accessible
# Permissions are based on single character flags: c (Create), r (read), w (write), d (delete), a (admin), * (all)
# For example defaultAcl={"acls": [{"scheme":"ip", "id":"192.168.1.192", "perms":"*"}, {"scheme":"ip", id":"192.168.1.0/24", "perms":"r"}]
defaultAcl=
# Set X-Forwarded-For to true if zkui is behind a proxy
X-Forwarded-For=false

 4.关于配置文件的说明：

   （1） 如果是zk集群，scmRepo=xxx.xxx.xx.xx:2181,xxx.xxx.xx.xx:2182,xxx.xxx.xx.xx:2183需要填写集群各个节点服务器（即  Zookeeper节点）的IP地址加端口号2181，我的zookeeper 集群是在同一台服务器部署伪集群，所以ip一样，端口不一样。
若报KeeperErrorCode = ConnectionLoss for / 错误，增大zkSessionTimeout超时时间，设置zkSessionTimeout=20

   （2）默认用户信息

     用户名：Admin（Admin权限，支持CRUD操作）
     密码：manager
     用户名：appconfig（Readonly权限，支持读取操作）
     密码：appconfig

   （3）LDAP的配置 　

     如果使用 LDAP 身份验证，则提供 LDAP url。
     这将优先于 roleSet property 文件认证。
     ldapUrl=ldap://<ldap_host>:<ldap_port>/dc=mycom,dc=com
     如果不提供此功能，则将使用默认 roleSet 文件认证。

三、运行zkui.jar

    1.创建zkui目录，把 zkui-2.0-SNAPSHOT-jar-with-dependencies.jar、config.cfg放在同一个目录zkui中。

cd zkui
 
nohup java -jar zkui-2.0-SNAPSHOT-jar-with-dependencies.jar >zkui.log &

   2.查看是否启动成功

netstat  -tunpl |grep  :9090

四、浏览器访问 http://xxx.xxx.xx.xx:9090/login　账号admin 密码manager

 五、问题

  1.点击Hosts时：

  2.查看日志信息：

tail -f zkui-out.log

 3.解决办法：

   （1）.查看docker 容器

docker ps

  （2）进入任意一个zookeeper节点

docker exec -it c2ab27ffbedd bash

root@c2ab27ffbedd:/apache-zookeeper-3.5.8-bin# ls
LICENSE.txt  NOTICE.txt  README.md  README_packaging.txt  bin  conf  docs  lib
root@c2ab27ffbedd:/apache-zookeeper-3.5.8-bin# cd bin/
root@c2ab27ffbedd:/apache-zookeeper-3.5.8-bin/bin# ls
README.txt  zkCleanup.sh  zkCli.cmd  zkCli.sh  zkEnv.cmd  zkEnv.sh  zkServer-initialize.sh  zkServer.cmd  zkServer.sh  zkTxnLogToolkit.cmd  zkTxnLogToolkit.sh

  执行命令：

zkCli.sh -server xxx.xx.xx.xx:2183

root@c2ab27ffbedd:/apache-zookeeper-3.5.8-bin/bin# zkCli.sh -server xxx.xx.xx.xx:2183
