k8s集群部署kafka
一、部署步骤
二、部署NFS并挂载共享目录
注：使用云产品的NAS存储可跳过此步骤
1、服务端安装NFS
[root@localhost ~]# yum -y install nfs-utils rpcbind
2、创建共享目录并设置权限
[root@localhost ~]# mkdir -p /data/{kafka,zookeeper}
[root@localhost ~]# chmod 755 -R /data/*
3、修改配置文件
[root@localhost ~]# cat >> /etc/exports<<EOF
/data/kafka *(rw,sync,no_root_squash)
/data/zookeeper *(rw,sync,no_root_squash)
EOF
4、服务端启动
[root@localhost ~]# systemctl start rpcbind.service
[root@localhost ~]# systemctl enable rpcbind
[root@localhost ~]# systemctl status rpcbind
[root@localhost ~]# systemctl start nfs.service
[root@localhost ~]# systemctl enable nfs
[root@localhost ~]# systemctl status nfs
5、客户端安装NFS
[root@localhost ~]# yum -y install nfs-utils rpcbind
6、客户端启动
[root@localhost ~]# systemctl start rpcbind.service
[root@localhost ~]# systemctl enable rpcbind
[root@localhost ~]# systemctl status rpcbind
[root@localhost ~]# systemctl start nfs.service
[root@localhost ~]# systemctl enable nfs
[root@localhost ~]# systemctl status nfs
7、查看共享目录
[root@localhost ~]# showmount -e 192.168.1.128
8、客户端挂载共享目录
[root@localhost ~]# mkdir -p /data/{kafka,zookeeper}
[root@localhost ~]# mount 192.168.1.128:/data/kafka /data/kafka
[root@localhost ~]# mount 192.168.1.128:/data/zookeeper /data/zookeeper
三、部署zookeeper集群
1、准备yaml文件

2、部署kafka集群
[root@localhost ~]# kubectl apply -f kafka.yaml
五、测试kafka
1、进入kafka集群容器
[root@localhost ~]# kubectl exec -it kafka-0 -n middleware
2、测试查询kafka的topic
kafka@kafka-0:/$ kafka-topics.sh --list --bootstrap-server 127.0.0.1:9092
