zookeeper 可视化界面（zkui）搭建与配置

准备环境

zookeeper可视化WEB工具 zkui 依赖java环境，因此需要安装JDK，zkui 源码需要maven编译，需要安装Apache-maven。
1、JDK 1.8 ：JDK下载地址 IT虾米网
或者安装openJDK ，命令如下：

  yum -y install java-1.8.0-openjdk java-1.8.0-openjdk-devel 

2、maven 3.0.5 ：Apache-maven下载地址 IT虾米网
3、centos 7，xshell，xftp

（1）设置环境变量

执行命令 vim /etc/profile 在文件末尾添加如下：

# set for nginx 
PATH=$PATH:/usr/local/nginx/sbin 
export PAT 
 
#zookeeper-3.4.14 config start 
export ZOOKEEPER_HOME=/usr/local/services/zookeeper-3.4.14 
export PATH=$ZOOKEEPER_HOME/bin:$PATH 
CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$ZOOKEEPER_HOME/lib: 
export ZOOKEEPER_HOME 
export JAVA_HOME 
export PATH 
export CLASSPATH 
export PATH 
#zookeeepr-3.4.14 config end 

查看版本号：

[root@localhost services]# java -version 
openjdk version "1.8.0_262" 
OpenJDK Runtime Environment (build 1.8.0_262-b10) 
OpenJDK 64-Bit Server VM (build 25.262-b10, mixed mode) 
[root@localhost services]# mvn -v 
Apache Maven 3.0.5 (Red Hat 3.0.5-17) 
Maven home: /usr/share/maven 
Java version: 1.8.0_262, vendor: Oracle Corporation

OS name: "linux", version: "3.10.0-1127.el7.x86_64", arch: "amd64", family: "unix" 
[root@localhost services]#  

搭建zkui

1、下载zkui

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

[root@localhost zkui]# ll 
总用量 100 
-rw-r--r--. 1 root root  2364 8月  12 10:53 config.cfg 
drwxr-xr-x. 2 root root    61 8月  12 10:28 docker 
drwxr-xr-x. 2 root root   114 8月  12 10:28 images

-rw-r--r--. 1 root root   416 8月  12 10:28 Makefile 
-rw-r--r--. 1 root root  1746 8月  12 10:28 nbactions.xml 
-rw-------. 1 root root  2103 8月  15 08:00 nohup.out 
-rw-r--r--. 1 root root  5294 8月  12 10:28 pom.xml 
-rw-r--r--. 1 root root  6216 8月  12 10:28 README.md 
-rw-r--r--. 1 root root    43 8月  12 10:28 run.sh 
drwxr-xr-x. 4 root root    30 8月  12 10:28 src 
drwxr-xr-x. 9 root root   264 8月  12 11:10 target 
-rw-r--r--. 1 root root 43008 8月  15 08:00 zkui.h2.db 
-rw-r--r--. 1 root root  5008 8月  15 08:01 zkui-out.log 
[root@localhost zkui]#  

2、编译zkui，生成jar包

[root@localhost services]# cd zkui/ 
[root@localhost zkui]# mvn clean install 
.................................编译过程省略.......................................... 
[INFO] --- maven-install-plugin:2.4:install (default-install) @ zkui --- 
[INFO] Installing /App/zkui/target/zkui-2.0-SNAPSHOT.jar to /root/.m2/repository/com/deem/zkui/2.0-SNAPSHOT/zkui-2.0-SNAPSHOT.jar 
[INFO] Installing /App/zkui/pom.xml to /root/.m2/repository/com/deem/zkui/2.0-SNAPSHOT/zkui-2.0-SNAPSHOT.pom

[INFO] ------------------------------------------------------------------------

[INFO] Finished at: 2019-04-15T09:57:44+08:00 
[INFO] ------------------------------------------------------------------------ 

编译成功后，会生成两个jar包，zkui-2.0-SNAPSHOT.jar 和zkui-2.0-SNAPSHOT-jar-with-dependencies.jar。使用的是第二个jar包。

[root@localhost zkui]# cd target 
[root@localhost target]# ll 
总用量 8420 
drwxr-xr-x. 2 root root       6 8月  12 10:57 archive-tmp 
drwxr-xr-x. 5 root root     101 8月  12 10:57 classes

-rw-r--r--. 1 root root  277164 8月  12 10:57 zkui-2.0-SNAPSHOT.jar 
-rw-r--r--. 1 root root 8336868 8月  12 10:57 zkui-2.0-SNAPSHOT-jar-with-dependencies.jar 
-rw-r--r--. 1 root root       0 8月  12 11:09 zkui-out.log 
[root@localhost target]#  

3、修改配置文件

修改zkui的配置文件 config.cfg ，config.cfg 文件中配置了 zkui 需要连接的 zookeeper 集群的 IP 地址和端口，访问 zkui 的用户名和密码，以及 zkui 监听的端口号。

#Server Port 
serverPort=9090 
#Comma seperated list of all the zookeeper servers 
zkServer=192.168.198.x:2181,localhost:2181 
#Http path of the repository. Ignore if you dont intent to upload files from repository. 
scmRepo=http://myserver.com/@rev1= 
#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 

注意：

• 如果zookeeper和zkui安装在同一台机器上，不需要修改config.cfg 配置文件也可启动。
• 默认用户信息：
  账号 root，密码 manager （Admin权限，支持CRUD操作）
  账号 appconfig ，密码 appconfig (Readonly权限，支持读取操作)
• LDAP的配置
  如果想使用 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。

4、启动zkui

[root@localhost zkui]# nohup java -jar target/zkui-2.0-SNAPSHOT-jar-with-dependencies.jar & 
[2] 1948 
[root@localhost zkui]# nohup: 忽略输入并把输出追加到"nohup.out" 
nohup: ignoring input and appending output to ‘nohup.out’ 
-bash: nohup:: 未找到命令 
[root@localhost zkui]# netstat  -tunpl |grep  :9090 
tcp6       0      0 :::9090                 :::*                    LISTEN      1694/java            
[root@localhost zkui]#  

浏览器访问 http://192.168.198.128:9090/login 账号admin，密码manager 即可看到zkui的管理界面。
（注意开放端口9090，访问之前注意关闭防火墙）
