------
|
||||
|
||||
## 一：环境准备
|
||||
|
||||
#### 1.kubernetes集群
|
||||
|
||||
集群正常运行，例如使用以下命令检查
|
||||
|
||||
```shell
|
||||
[root@master ~]# kubectl get node
|
||||
NAME STATUS ROLES AGE VERSION
|
||||
master Ready control-plane,master 5d19h v1.23.1
|
||||
node-1 Ready <none> 5d19h v1.23.1
|
||||
node-2 Ready <none> 5d19h v1.23.1
|
||||
node-3 Ready <none> 5d19h v1.23.1
|
||||
```
|
||||
|
||||
#### 2.harbor私有仓库
|
||||
|
||||
主要给kubernetes集群提供镜像服务
|
||||
|
||||
<img src="https://xingdian-image.oss-cn-beijing.aliyuncs.com/xingdian-image/image-20220502184026483.png" alt="image-20220502184026483" style="zoom:50%;" />
|
||||
## 二：项目部署
|
||||
|
||||
#### 1.镜像构建
|
||||
|
||||
软件下载地址：
|
||||
|
||||
```shell
|
||||
wget https://nginx.org/download/nginx-1.20.2.tar.gz
|
||||
```
|
||||
|
||||
项目包下载地址：
|
||||
|
||||
```shell
|
||||
git clone https://github.com/blackmed/xingdian-project.git
|
||||
```
|
||||
|
||||
构建centos基础镜像Dockerfile文件：
|
||||
|
||||
```shell
|
||||
root@nfs-harbor ~]# cat Dockerfile
|
||||
FROM daocloud.io/centos:7
|
||||
MAINTAINER "xingdianvip@gmail.com"
|
||||
ENV container docker
|
||||
RUN yum -y swap -- remove fakesystemd -- install systemd systemd-libs
|
||||
RUN yum -y update; yum clean all; \
|
||||
(cd /lib/systemd/system/sysinit.target.wants/; for i in *; do [ $i == systemd-tmpfiles-setup.service ] || rm -f $i; done); \
|
||||
rm -f /lib/systemd/system/multi-user.target.wants/*;\
|
||||
rm -f /etc/systemd/system/*.wants/*;\
|
||||
rm -f /lib/systemd/system/local-fs.target.wants/*; \
|
||||
rm -f /lib/systemd/system/sockets.target.wants/*udev*; \
|
||||
rm -f /lib/systemd/system/sockets.target.wants/*initctl*; \
|
||||
rm -f /lib/systemd/system/basic.target.wants/*;\
|
||||
rm -f /lib/systemd/system/anaconda.target.wants/*;
|
||||
VOLUME [ "/sys/fs/cgroup" ]
|
||||
CMD ["/usr/sbin/init"]
|
||||
root@nfs-harbor ~]# docker bulid -t xingdian .
|
||||
```
|
||||
|
||||
构建项目镜像：
|
||||
|
||||
```shell
|
||||
[root@nfs-harbor nginx]# cat Dockerfile
|
||||
FROM xingdian
|
||||
ADD nginx-1.20.2.tar.gz /usr/local
|
||||
RUN rm -rf /etc/yum.repos.d/*
|
||||
COPY CentOS-Base.repo /etc/yum.repos.d/
|
||||
COPY epel.repo /etc/yum.repos.d/
|
||||
RUN yum clean all && yum makecache fast
|
||||
RUN yum -y install gcc gcc-c++ openssl openssl-devel pcre-devel zlib-devel make
|
||||
WORKDIR /usr/local/nginx-1.20.2
|
||||
RUN ./configure --prefix=/usr/local/nginx
|
||||
RUN make && make install
|
||||
WORKDIR /usr/local/nginx
|
||||
ENV PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/nginx/sbin
|
||||
EXPOSE 80
|
||||
RUN rm -rf /usr/local/nginx/conf/nginx.conf
|
||||
COPY nginx.conf /usr/local/nginx/conf/
|
||||
RUN mkdir /dist
|
||||
CMD ["nginx", "-g", "daemon off;"]
|
||||
[root@nfs-harbor nginx]# docker build -t nginx:v2 .
|
||||
```
|
||||
|
||||
注意：
|
||||
|
||||
需要事先准备好Centos的Base仓库和epel仓库
|
||||
|
||||
#### 2.上传项目到harbor
|
||||
|
||||
修改镜像tag：
|
||||
|
||||
```shell
|
||||
[root@nfs-harbor ~]# docker tag nginx:v2 10.0.0.230/xingdian/nginx:v2
|
||||
```
|
||||
|
||||
登录私有仓库：
|
||||
|
||||
```shell
|
||||
[root@nfs-harbor ~]# docker login 10.0.0.230
|
||||
Username: xingdian
|
||||
Password:
|
||||
```
|
||||
|
||||
上传镜像：
|
||||
|
||||
```shell
|
||||
[root@nfs-harbor ~]# docker push 10.0.0.230/xingdian/nginx:v2
|
||||
```
|
||||
|
||||
注意：
|
||||
|
||||
默认上传时采用https，因为我们部署的harbor使用的是http，所以再上传之前按照3-1进行修改
|
||||
|
||||
#### 3.kubernetes集群连接harbor
|
||||
|
||||
修改所有kubernetes集群能够访问http仓库，默认访问的是https
|
||||
|
||||
```shell
|
||||
[root@master ~]# vim /etc/systemd/system/multi-user.target.wants/docker.service
|
||||
ExecStart=/usr/bin/dockerd -H fd:// --insecure-registry 10.0.1.13 --containerd=/run/containerd/containerd.sock
|
||||
[root@master ~]# systemctl daemon-reload
|
||||
[root@master ~]# systemctl restart docker
|
||||
```
|
||||
|
||||
kubernetes集群创建secret用于连接harbor
|
||||
|
||||
```shell
|
||||
[root@master ~]# kubectl create secret docker-registry regcred --docker-server=10.0.0.230 --docker-username=diange --docker-password=QianFeng@123
|
||||
[root@master ~]# kubectl get secret
|
||||
NAME TYPE DATA AGE
|
||||
regcred kubernetes.io/dockerconfigjson 1 19h
|
||||
```
|
||||
|
||||
注意：
|
||||
|
||||
regcred：secret的名字
|
||||
|
||||
--docker-server：指定服务器的地址
|
||||
|
||||
--docker-username：指定harbor的用户
|
||||
|
||||
--docker-password：指定harbor的密码
|
||||
|
||||
#### 4.部署NFS
|
||||
|
||||
部署NFS目的是为了给kubernetes集群提供持久化存储,kubernetes集群也要安装nfs-utils目的是为了支持nfs文件系统
|
||||
|
||||
```shell
|
||||
[root@nfs-harbor ~]# yum -y install nfs-utils
|
||||
[root@nfs-harbor ~]# systemctl start nfs
|
||||
[root@nfs-harbor ~]# systemctl enable nfs
|
||||
```
|
||||
|
||||
创建共享目录并对外共享
|
||||
|
||||
```shell
|
||||
[root@nfs-harbor ~]# mkdir /kubernetes-1
|
||||
[root@nfs-harbor ~]# cat /etc/exports
|
||||
/kubernetes-1 *(rw,no_root_squash,sync)
|
||||
[root@nfs-harbor ~]# exportfs -rv
|
||||
```
|
||||
|
||||
项目放入共享目录下
|
||||
|
||||
```shell
|
||||
[root@nfs-harbor ~]# git clone https://github.com/blackmed/xingdian-project.git
|
||||
[root@nfs-harbor ~]# unzip dist.zip
|
||||
[root@nfs-harbor ~]# cp -r dist/* /kubernetes-1
|
||||
```
|
||||
|
||||
#### 5.创建statefulset部署项目
|
||||
|
||||
该yaml文件中除了statefulset以外还有service、PersistentVolume、StorageClass
|
||||
|
||||
```shell
|
||||
[root@master xingdian]# cat Statefulset.yaml
|
||||
apiVersion: v1
|
||||
kind: Service
|
||||
metadata:
|
||||
name: nginx
|
||||
labels:
|
||||
app: nginx
|
||||
spec:
|
||||
type: NodePort
|
||||
ports:
|
||||
- port: 80
|
||||
name: web

<h1><center>基于Kubernetes集群构建ES集群</center></h1>
|
||||
|
||||
|
||||
|
||||
------
|
||||
|
||||
## 一：环境准备
|
||||
|
||||
#### 1.Kubernetes集群环境
|
||||
|
||||
| 节点 | 地址 |
|
||||
| :---------------: | :---------: |
|
||||
| Kubernetes-Master | 10.9.12.206 |
|
||||
| Kubernetes-Node-1 | 10.9.12.205 |
|
||||
| Kubernetes-Node-2 | 10.9.12.204 |
|
||||
| Kubernetes-Node-3 | 10.9.12.203 |
|
||||
| DNS服务器 | 10.9.12.210 |
|
||||
| 代理服务器 | 10.9.12.209 |
|
||||
| NFS存储 | 10.9.12.250 |
|
||||
|
||||
#### 2.Kuboard集群管理
|
||||
|
||||
|
||||
|
||||
## 二：构建ES集群
|
||||
|
||||
#### 1.持久化存储构建
|
||||
|
||||
1.NFS服务器部署
|
||||
|
||||
略
|
||||
|
||||
2.创建共享目录
|
||||
|
||||
本次采用脚本创建，脚本如下
|
||||
|
||||
```shell
|
||||
[root@xingdiancloud-1 ~]# cat nfs.sh
|
||||
#!/bin/bash
|
||||
read -p "请输入您要创建的共享目录：" dir
|
||||
if [ -d $dir ];then
|
||||
echo "请重新输入共享目录: "
|
||||
read again_dir
|
||||
mkdir $again_dir -p
|
||||
echo "共享目录创建成功"
|
||||
read -p "请输入共享对象：" ips
|
||||
echo "$again_dir ${ips}(rw,sync,no_root_squash)" >> /etc/exports
|
||||
xingdian=`cat /etc/exports |grep "$again_dir" |wc -l`
|
||||
if [ $xingdian -eq 1 ];then
|
||||
echo "成功配置共享"
|
||||
exportfs -rv >/dev/null
|
||||
exit
|
||||
else
|
||||
exit
|
||||
fi
|
||||
else
|
||||
mkdir $dir -p
|
||||
echo "共享目录创建成功"
|
||||
read -p "请输入共享对象：" ips
|
||||
echo "$dir ${ips}(rw,sync,no_root_squash)" >> /etc/exports
|
||||
xingdian=`cat /etc/exports |grep "$dir" |wc -l`
|
||||
if [ $xingdian -eq 1 ];then
|
||||
echo "成功配置共享"
|
||||
exportfs -rv >/dev/null
|
||||
exit
|
||||
else
|
||||
exit
|
||||
fi
|
||||
fi
|
||||
```
|
||||
|
||||
3.创建存储类
|
||||
|
||||
```yaml
|
||||
[root@xingdiancloud-master ~]# vim namespace.yaml
|
||||
apiVersion: v1
|
||||
kind: Namespace
|
||||
metadata:
|
||||
name: logging
|
||||
[root@xingdiancloud-master ~]# vim storageclass.yaml
|
||||
apiVersion: storage.k8s.io/v1
|
||||
kind: StorageClass
|
||||
metadata:
|
||||
annotations:
|
||||
k8s.kuboard.cn/storageNamespace: logging
|
||||
k8s.kuboard.cn/storageType: nfs_client_provisioner
|
||||
name: data-es
|
||||
parameters:
|
||||
archiveOnDelete: 'false'
|
||||
provisioner: nfs-data-es
|
||||
reclaimPolicy: Retain
|
||||
volumeBindingMode: Immediate
|
||||
```
|
||||
|
||||
4.创建存储卷
|
||||
|
||||
```yaml
|
||||
[root@xingdiancloud-master ~]# vim persistenVolume.yaml
|
||||
apiVersion: v1
|
||||
kind: PersistentVolume
|
||||
metadata:
|
||||
annotations:
|
||||
pv.kubernetes.io/bound-by-controller: 'yes'
|
||||
finalizers:
|
||||
- kubernetes.io/pv-protection
|
||||
name: nfs-pv-data-es
|
||||
spec:
|
||||
accessModes:
|
||||
- ReadWriteMany
|
||||
capacity:
|
||||
storage: 100Gi
|
||||
claimRef:
|
||||
apiVersion: v1
|
||||
kind: PersistentVolumeClaim
|
||||
name: nfs-pvc-data-es
|
||||
namespace: kube-system
|
||||
nfs:
|
||||
path: /data/es-data
|
||||
server: 10.9.12.250
|
||||
persistentVolumeReclaimPolicy: Retain
|
||||
storageClassName: nfs-storageclass-provisioner
|
||||
volumeMode: Filesystem
|
||||
```
|
||||
|
||||
注意：存储类和存储卷也可以使用Kuboard界面创建
|
||||
|
||||
#### 2.设定节点标签
|
||||
|
||||
```shell
|
||||
[root@xingdiancloud-master ~]# kubectl label nodes xingdiancloud-node-1 es=log
|
||||
```
|
||||
|
||||
注意：
|
||||
|
||||
所有运行ES的节点需要进行标签的设定
|
||||
|
||||
目的配合接下来的StatefulSet部署ES集群
|
||||
|
||||
#### 3.ES集群部署
|
||||
|
||||
注意：由于ES集群每个节点需要唯一的网络标识，并需要持久化存储，Deployment不能实现该特点只能进行无状态应用的部署，故本次将采用StatefulSet进行部署。
|
||||
|
||||
```yaml
|
||||
apiVersion: apps/v1
|
||||
kind: StatefulSet
|
||||
metadata:
|
||||

|
||||
namespace: logging

|
||||
initContainers:
|
||||

|
||||
```
|
||||
|
||||
#### 4.创建Services发布ES集群
|
||||
|
||||
```yaml
|
||||
[root@xingdiancloud-master ~]# vim elasticsearch-svc.yaml
|
||||
kind: Service
|
||||
apiVersion: v1
|
||||
metadata:
|
||||
name: elasticsearch
|
||||
namespace: logging
|
||||
labels:
|
||||
app: elasticsearch
|
||||
spec:
|
||||
selector:
|
||||
app: elasticsearch
|
||||
type: NodePort
|
||||
ports:
|
||||
- port: 9200
|
||||
targetPort: 9200
|
||||
nodePort: 30010
|
||||
name: rest
|
||||
- port: 9300
|
||||
name: inter-node
|
||||
```
|
||||
|
||||
#### 5.访问测试
|
||||
|
||||
注意：
|
||||
|
||||
使用elasticVUE插件访问集群
|
||||
|
||||
集群状态正常
|
||||
|
||||
集群所有节点正常
|
||||
|
||||
|
||||
|
||||
## 三：代理及DNS配置
|
||||
|
||||
#### 1.代理配置
|
||||
|
||||
注意：
|
||||
|
||||
部署略
|
||||
|
||||
在此使用Nginx作为代理
|
||||
|
||||
基于用户的访问控制用户和密码自行创建（htpasswd）
|
||||
|
||||
配置文件如下
|
||||
|
||||
```shell
|
||||
[root@proxy ~]# cat /etc/nginx/conf.d/elasticsearch.conf
|
||||
server {
|
||||
listen 80;
|
||||
server_name es.xingdian.com;
|
||||
location / {
|
||||
auth_basic "xingdiancloud kibana";
|
||||
auth_basic_user_file /etc/nginx/pass;
|
||||
proxy_pass http://地址+端口;
|
||||
|
||||
}
|
||||
|
||||
|
||||
}
|
||||
```
|
||||
|
||||
#### 2.域名解析配置
|
||||
|
||||
注意：
|
||||
|
||||
部署略
|
||||
|
||||
配置如下
|
||||
|
||||
```shell
|
||||
[root@www ~]# cat /var/named/xingdian.com.zone
|
||||
$TTL 1D
|
||||
@ IN SOA @ rname.invalid. (
|
||||
0 ; serial
|
||||
1D ; refresh
|
||||
1H ; retry
|
||||
1W ; expire
|
||||
3H ) ; minimum
|
||||
NS @
|
||||
A DNS地址
|
||||
es A 代理地址
|
||||
AAAA ::1
|
||||
```
|
||||
|
||||
