開(kāi)整Ｖ槠晚缩！
第一步，準(zhǔn)備3臺(tái)虛擬機(jī)媳危，系統(tǒng)為CentOS 7荞彼，如下
| IP | 角色 |
|---|---|
| 172.16.31.191 | zookeeper-1 |
| 172.16.31.192 | zookeeper-2 |
| 172.16.31.193 | zookeeper-3 |
第二步，在虛擬機(jī)上裝好docker并啟動(dòng)（不會(huì)使用 docker 的話請(qǐng)先百度了解一下）待笑，3臺(tái)虛擬機(jī)都要
第三步鸣皂，創(chuàng)建存儲(chǔ)目錄 /usr/local/docker/zookeeper，3臺(tái)虛擬機(jī)都要暮蹂，如下
mkdir /usr/local/docker/zookeeper
并創(chuàng)建相關(guān)掛載目錄签夭，3臺(tái)虛擬機(jī)都要，如下
mkdir /usr/local/docker/zookeeper/config
mkdir /usr/local/docker/zookeeper/data
第四步椎侠，在 /usr/local/docker/zookeeper/config 目錄下新建 zoo.cfg 配置文件第租，3臺(tái)虛擬機(jī)都要，內(nèi)容一樣我纪，如下
vim /usr/local/docker/zookeeper/config/zoo.cfg
zoo.cfg
clientPort=2181
dataDir=/data
dataLogDir=/data/log
tickTime=2000
initLimit=5
syncLimit=2
autopurge.snapRetainCount=3
autopurge.purgeInterval=0
maxClientCnxns=60
4lw.commands.whitelist=*
server.1=172.16.31.191:2888:3888
server.2=172.16.31.192:2888:3888
server.3=172.16.31.193:2888:3888
另外慎宾，還要在 /usr/local/docker/zookeeper/data 目錄下新建 myid 配置文件，里面的內(nèi)容編號(hào)不能重復(fù)浅悉，3臺(tái)虛擬機(jī)都要趟据，如下
172.16.31.191
# 創(chuàng)建 myid 配置文件
touch /usr/local/docker/zookeeper/data/myid
# 添加配置 1 ，此編號(hào)代表選舉的時(shí)候的編號(hào)
echo 1 > /usr/local/docker/zookeeper/data/myid
172.16.31.192
# 創(chuàng)建 myid 配置文件
touch /usr/local/docker/zookeeper/data/myid
# 添加配置 2 术健，此編號(hào)代表選舉的時(shí)候的編號(hào)
echo 2 > /usr/local/docker/zookeeper/data/myid
172.16.31.193
# 創(chuàng)建 myid 配置文件
touch /usr/local/docker/zookeeper/data/myid
# 添加配置 3 汹碱，此編號(hào)代表選舉的時(shí)候的編號(hào)
echo 3 > /usr/local/docker/zookeeper/data/myid
第五步，docker方式啟動(dòng) Zookeeper 3.6.1荞估，3臺(tái)虛擬機(jī)都要咳促，如下
172.16.31.191
docker run --network host -v /usr/local/docker/zookeeper/data:/data -v /usr/local/docker/zookeeper/conf/zoo.cfg:/conf/zoo.cfg --name zookeeper-1 -d zookeeper:3.6.1
172.16.31.192
docker run --network host -v /usr/local/docker/zookeeper/data:/data -v /usr/local/docker/zookeeper/conf/zoo.cfg:/conf/zoo.cfg --name zookeeper-2 -d zookeeper:3.6.1
172.16.31.193
docker run --network host -v /usr/local/docker/zookeeper/data:/data -v /usr/local/docker/zookeeper/conf/zoo.cfg:/conf/zoo.cfg --name zookeeper-3 -d zookeeper:3.6.1
第五步，任選一臺(tái)虛擬機(jī)配置 zookeeper-ui 可視化管理界面勘伺，我選的是 172.16.31.191跪腹，虛擬機(jī)需要配置好 jdk 環(huán)境！如下
1飞醉、上 GitHub 拉取最新代碼： https://github.com/DeemOpen/zkui
git clone https://github.com/DeemOpen/zkui.git
2冲茸、打開(kāi)項(xiàng)目，進(jìn)入根目錄進(jìn)行編譯打包
mvn clean install
3缅帘、打包完后將 target 目錄下的 zkui-2.0-SNAPSHOT-jar-with-dependencies.jar 包上傳到 /usr/local/docker/zookeeper/zookeeper-ui 目錄下
4轴术、進(jìn)入 /usr/local/docker/zookeeper/zookeeper-ui 目錄，創(chuàng)建 config.cfg 配置文件钦无，如下
cd /usr/local/docker/zookeeper/zookeeper-ui
vim config.cfg
config.cfg
#Server Port
serverPort=9090
#Comma seperated list of all the zookeeper servers
zkServer=172.16.31.191:2181,172.16.31.192:2181,172.16.31.193:2181
#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":"admin","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
5逗栽、保存后啟動(dòng)項(xiàng)目，如下
nohup java -jar zkui-2.0-SNAPSHOT-jar-with-dependencies.jar &
第六步铃诬，訪問(wèn) 172.16.31.191:9090 查看集群狀態(tài)祭陷，如下
注意苍凛，賬號(hào)密碼在 config.cfg 里面的 userSet 配置選項(xiàng)，我配置為 admin/admin兵志，如下能查到各個(gè)節(jié)點(diǎn)的信息醇蝴，則表示集群部署成功
