8.实战交付一套dubbo微服务到k8s集群(1)之Zookeeper部署

1.基础架构

Dubbo微服务概述

 实验架构

2.部署zookeeper

2.1.安装JDK1.8(3台zk角色主机)

jdk下载地址：https://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

[root@hdss7-11 src]# mkdir /usr/java 
[root@hdss7-11 src]# tar xf jdk-8u221-linux-x64.tar.gz -C /usr/java/
[root@hdss7-11 src]# cd /usr/java/
[root@hdss7-11 java]# ln -s jdk1.8.0_221/ jdk
[root@hdss7-11 ~]# vim /etc/profile
export JAVA_HOME=/usr/java/jdk
export PATH=$JAVA_HOME/bin:$JAVA_HOME/bin:$PATH
export CLASSPATH=$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/lib/tools.jar
[root@hdss7-11 ~]# source /etc/profile

2.2.安装zookeeper(3台zk角色主机)

zookeeper官方地址：https://zookeeper.apache.org/

zookeeper下载地址：https://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/zookeeper-3.6.1/apache-zookeeper-3.6.1-bin.tar.gz

[root@hdss7-11 src]# tar xf zookeeper-3.4.14.tar.gz -C /opt
[root@hdss7-11 opt]# ln -s zookeeper-3.4.14/ zookeeper
[root@hdss7-11 opt]# mkdir -pv /data/zookeeper/{data,logs}
[root@hdss7-11 ~]# vim /opt/zookeeper/conf/zoo.cfg
tickTime=2000
initLimit=10
syncLimit=5
dataDir=/data/zookeeper/data
dataLogDir=/data/zookeeper/logs
clientPort=2181
server.1=zk1.fx.com:2888:3888
server.2=zk2.fx.com:2888:3888
server.3=zk3.fx.com:2888:3888

2.3.为zookeeper提供myid

[root@hdss7-11 ~]# vim /data/zookeeper/data/myid
1

[root@hdss7-12 ~]# vim /data/zookeeper/data/myid
2

[root@hdss7-21 ~]# vim /data/zookeeper/data/myid
3

2.4.配置DNS解析

[root@hdss7-11 ~]# vim /var/named/fx.com.zone 
$ORIGIN fx.com.
$TTL 600        ; 10 minutes
@               IN SOA  dns.fx.com. dnsadmin.fx.com. (
                        2020061011  ; serial
                         10800      ; refresh (3 hours)
                         900        ; retry (15 minutes)
                         604800     ; expire (1 week)
                         86400      ; minimum (1 day)
                         )
                        NS      dns.fx.com.
$TTL 60 ; 1 minute
dns             A       10.4.7.11
harbor          A       10.4.7.200
k8s-yaml        A       10.4.7.200
traefik         A       10.4.7.10
dashboard       A       10.4.7.10
zk1             A       10.4.7.11
zk2             A       10.4.7.12
zk3             A       10.4.7.21
[root@hdss7-11 ~]# systemctl restart named

 2.5.启动zookeeper

[root@hdss7-11 ~]#  /opt/zookeeper/bin/zkServer.sh start
ZooKeeper JMX enabled by default
Using config: /opt/zookeeper/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED

2.6.查看zookeeper信息

[root@hdss7-11 ~]# /opt/zookeeper/bin/zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /opt/zookeeper/bin/../conf/zoo.cfg
Mode: follower
[root@hdss7-12 ~]# /opt/zookeeper/bin/zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /opt/zookeeper/bin/../conf/zoo.cfg
Mode: leader
[root@hdss7-21 ~]# /opt/zookeeper/bin/zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /opt/zookeeper/bin/../conf/zoo.cfg
Mode: follower
