一: JDK1.8安装

参考: Centos7卸载|安装JDK1.8|Xshell7批量控制多个终端

二：Maven安装

2.1：下载maven安装包

maven 下载地址：https://mirror.bit.edu.cn/apache/maven/maven-3/

[root@www ~]# mkdir -p /usr/local/maven
[root@www ~]# cd /usr/local/tools
[root@www tools]# wget https://mirror.bit.edu.cn/apache/maven/maven-3/3.8.8/binaries/apache-maven-3.8.8-bin.tar.gz
--2023-08-27 12:44:30-- https://mirror.bit.edu.cn/apache/maven/maven-3/3.8.8/binaries/apache-maven-3.8.8-bin.tar.gz

2023-08-27 12:44:32 (3.84 MB/s) - 已保存 “apache-maven-3.8.8-bin.tar.gz” [8296049/8296049])

2.2：解压maven安装包到/usr/local/maven目录

[root@www tools]# ll

[root@www maven]# ll
总用量 0
drwxr-xr-x 6 root root 99 8月 27 12:45 apache-maven-3.8.8
[root@www maven]# cd apache-maven-3.8.8/
[root@www apache-maven-3.8.8]# clear
[root@www apache-maven-3.8.8]# pwd
/usr/local/maven/apache-maven-3.8.8
[root@www apache-maven-3.8.8]# echo 'export PATH=/usr/local/maven/apache-maven-3.8.8/bin:$PATH' >>/etc/profile
[root@www apache-maven-3.8.8]# source /etc/profile

2.3：配置阿里云仓库镜像

[root@www conf]# pwd
/usr/local/maven/apache-maven-3.8.8/conf

[root@www conf]# mkdir -p /usr/local/maven/repository

[root@www conf]# vi settings.xml



<mirror>
<id>alimaven</id>
<name>aliyun maven</name>
<url>http://maven.aliyun.com/nexus/content/groups/public/</url>
<mirrorOf>central</mirrorOf>
</mirror>

三: 在线安装Git

[root@www conf]# yum install git -y
[root@www conf]# git --version
git version 1.8.3.1

四：安装zookeeper服务

参考：使用Xshell7控制多台服务同时安装ZK最新版集群服务

五：安装zkui

下载地址: mirrors / DeemOpen / zkui · GitCode

[root@www conf]# mkdir -p /usr/local/zkui

[root@www zkui]# git clone https://gitcode.net/mirrors/DeemOpen/zkui.git

[root@www zkui]# cd zkui/
[root@www zkui]# mvn clean install -DskipTests

看到如图所示,即打包成功了;

六：准备配置文件并启动服务

[root@www zkui]# cat config.cfg
#Server Port
serverPort=9999
#Comma seperated list of all the zookeeper servers
zkServer=192.168.1.100:2181,192.168.1.101:2181,192.168.1.102:2181

-rwxr-xr-x 1 root root 1252 8月 27 13:51 zkui.sh

七：脚本启动:

[root@www zkui]# cat zkui.sh
#!/usr/bin/env bash

PIDFILE=~/zkui.pid
ZKUIBINDIR=$(cd `dirname $0`; pwd)
ZKUICLASSNAME="target/zkui-2.0-SNAPSHOT-jar-with-dependencies.jar"
ZKUI_DAEMON_OUT=$ZKUIBINDIR/zkui.out

start(){
echo "Starting zkui ... $ZKUIBINDIR"
if [ -f "$PIDFILE" ]; then
if kill -0 `cat "$PIDFILE"` > /dev/null 2>&1; then
echo zkui already running as process `cat "$PIDFILE"`.
exit 0
fi
fi
cp config.cfg target
nohup java -jar "$ZKUIBINDIR/$ZKUICLASSNAME" > "$ZKUI_DAEMON_OUT" 2>&1 < /dev/null &
if [ $? -eq 0 ];
then
echo $!>$PIDFILE
if [ $? -eq 0 ];
then
sleep 1
echo STARTED
else
echo FAILED TO WRITE PID
exit 1
fi
else
echo SERVER DID NOT START
exit 1
fi
}

stop(){
echo -n "Stopping zkui ... "
if [ ! -f "$PIDFILE" ]
then
echo "no zkui to stop (could not find file $PIDFILE)"
else
kill -9 $(cat "$PIDFILE")
rm "$PIDFILE"
echo STOPPED
fi
exit 0
}

case "$1" in
start)
start
;;
stop)
stop
;;
restart)
shift
"$0" stop
sleep 3
"$0" start
;;
*)
echo "Usage: $0 {start|stop|restart}" >&2
esac

执行命令启动服务

八：浏览器访问：

http://192.168.1.111:9999/login

输入: admin/manager 登录

九： “stat is not executed because it is not in the whitelist.” 异常解决

原因
zookeeper.4lw.commands.whitelist：3.4.10中的新增功能：此属性包含以逗号分隔的四个字母单词命令的列表。引入它是为了对ZooKeeper可执行的命令集提供精细的控制，因此用户可以在必要时关闭某些命令。默认情况下，如果未指定该属性，则它包含所有受支持的四个字母单词命令，但“ wchp”和“ wchc”除外。如果指定了属性，则仅启用白名单中列出的命令。

解决方案: 在zoo.cfg文件中添加

在zookeeper配置中新增

4lw.commands.whitelist=*

十：修改后重启，再次查看
