一、准备环境
1、准备服务器
master1 :192.168.37.11 centos7.5 + 8cpu + 16G(内存) + 20G(/) + 200G ( data) + 200G(mnt)
master2 :192.168.37.12 centos7.5 + 8cpu + 16G(内存) + 20G(/) + 200G ( data)
master3 :192.168.37.13 centos7.5 + 8cpu + 16G(内存) + 20G(/) + 200G ( data)
node1: 192.168.37.14 centos7.5 + 8cpu + 16G(内存) + 20G(/) + 1T ( data)
node2: 192.168.37.15 centos7.5 + 8cpu + 16G(内存) + 20G(/) + 1T ( data)
node3: 192.168.37.16 centos7.5 + 8cpu + 16G(内存) + 20G(/) + 1T ( data)
node4: 192.168.37.17 centos7.5 + 8cpu + 16G(内存) + 20G(/) + 1T ( data)
nfs-server:192.168.18 centos7.5 + 4cpu + 8G(内存) + 20G(/) + 2T ( data)
2、安装工具服务
(1)安装jdk1.8
(2)安装nfs服务 (后面需要修改vas.yml文件中的配置)
// 安装nfs: # yum -y install nfs-utils # vim /etc/exports /opt/kubesphere 192.168.37.0/24(rw,no_root_squash) //启动nfs服务 #systemctl start nfs
#systemctl enable nfs
二、下载安装kubesphere
1、离线下载
curl -L https://kubesphere.io/download/offline/advanced-2.0.2 > advanced-2.0.2.tar.gz tar -zxf advanced-2.0.2.tar.gz cd kubesphere-all-offline-advanced-2.0.2/conf
2、 修改配置文件 vars.yml
# vim kubesphere-all-offline-advanced-2.0.2/conf/vars.yml nfs_client_enable: true nfs_client_is_default_class: true nfs_server: 192.168.37.18 nfs_path: /opt/kubesphere local_volume_provisioner_enabled: false local_volume_is_default_class: false
3、修改配置文件hosts.ini
[all] master1 ansible_connection=local ip=192.168.37.11 ansible_ssh_pass=root master2 ansible_host=192.168.37.12 ip=192.168.37.12 ansible_ssh_pass=root
master3 ansible_host=192.168.37.13 ip=192.168.37.13 ansible_ssh_pass=root
node1 ansible_host=192.168.37.167 ip=192.168.37.167 ansible_ssh_pass=root
node2 ansible_host=192.168.37.167 ip=192.168.37.167 ansible_ssh_pass=root
node2 ansible_host=192.168.37.167 ip=192.168.37.167 ansible_ssh_pass=root
node2 ansible_host=192.168.37.167 ip=192.168.37.167 ansible_ssh_pass=root
[local-registry]master1
[kube-master] master1
master2
master3
[kube-node]
node1
node2
node3
node4
[etcd]
master1
master2
master3
[k8s-cluster:children] kube-node kube-master
4、配置docker安装
由于docker占用空间较大,将docker软连接到挂载了大磁盘的 data 目录下
mkdir -p /data/docker
mkdir -p /data/kubelet
ln -sf /data/docker /var/lib/docker
ln -sf /data/kubelet /var/lib/kubelet
添加一个daemon.json文件:
# mkdir -p /etc/docker
# vim /etc/docker/daemon.json { "bip": "10.20.0.1/16", "fixed-cidr": "10.20.0.0/16", "mtu": 1500 }
mnt目录挂载一个大磁盘的原因是,docker的registry默认的安装目录是 /mnt 。。
5、安装
successsful!

5、注意
三、测试kubesphere集群
1、web端登陆:
输入“ http://192.168.37.11:30880 ” ,进入登陆界面,
登陆的用户名和密码是成功安装系统时默认给出的
Console: http://192.168.37.11:30880
Account: admin
Password: P@88w0rd
2、进入服务修改登陆密码,测试集群的node是否可用。
