系统环境：

Apollo 版本：1.4.0
Kubernetes 版本：1.14.0

参考：

Apollo Github 地址：https://github.com/ctripcorp/apollo

注意：部署比较复杂，极容易出错，请严格按步骤执行！

一、Apollo 简介

Apollo（阿波罗）是携程框架部门研发的分布式配置中心，能够集中化管理应用不同环境、不同集群的配置，配置修改后能够实时推送到应用端，并且具备规范的权限、流程治理等特性，适用于微服务配置管理场景。

服务端基于 Spring Boot 和 Spring Cloud 开发，打包后可以直接运行，不需要额外安装Tomcat等应用容器。且 Java 客户端不依赖任何框架，能够运行于所有 Java 运行时环境，同时对 Spring/Spring Boot 环境也有较好的支持。

二、Apollo 特性

部署简单
灰度发布
版本发布管理
提供开放平台API
客户端配置信息监控
提供Java和.Net原生客户端
配置修改实时生效（热发布）
权限管理、发布审核、操作审计
统一管理不同环境、不同集群的配置

三、Apollo 环境描述

Apollo 提供了四套环境配置:

DEV：开发环境
FAT：功能验收测试环境，用于软件测试者测试使用
UAT：用户验收测试环境，用于生产环境下的软件测试者测试使用
PRO：生成环境

每个环境都需要安装相应组件，这里为了简单，只部署 DEV 与 PRO 环境。

四、获取 apollo 压缩包

从 https://github.com/ctripcorp/apollo/releases 下载预先打好的 zip 包：

apollo-1.4.0.zip
apollo-portal-1.4.0-github.zip
apollo-adminservice-1.4.0-github.zip
apollo-configservice-1.4.0-github.zip

 1#下载 Apollo 源码
 2$ wget https://github.com/ctripcorp/apollo/archive/v1.4.0.zip
 3
 4#下载 Apollo Admin Server
 5$ wget https://github.com/ctripcorp/apollo/releases/download/v1.4.0/apollo-adminservice-1.4.0-github.zip
 6
 7#下载 Apollo Config Service
 8$ wget https://github.com/ctripcorp/apollo/releases/download/v1.4.0/apollo-configservice-1.4.0-github.zip
 9
10#下载 Apollo Portal
11$ wget https://github.com/ctripcorp/apollo/releases/download/v1.4.0/apollo-portal-1.4.0-github.zip

五、解压 apollo 压缩包

将源码包中部署文件复制到自定义目录：

1#解压源码包
2$ unzip v1.4.0.zip
3
4#创建用于部署的自定义文件夹
5$ mkdir ./deploy
6
7#将部署文件和脚本复制到自定义 deploy 目录
8$ cp -R ./apollo-1.4.0/scripts/apollo-on-kubernetes/* ./deploy

解压三个组件并放置在 deploy 目录下对应的文件夹下：

1#解压各个组件压缩包
2$ unzip -o apollo-configservice-1.4.0-github.zip -d ./deploy/apollo-config-server/
3$ unzip -o  apollo-adminservice-1.4.0-github.zip -d ./deploy/apollo-admin-server/
4$ unzip -o apollo-portal-1.4.0-github.zip        -d ./deploy/apollo-portal-server/
5
6#应用 Jar 重命名
7$ mv ./deploy/apollo-config-server/apollo-configservice-1.4.0.jar ./deploy/apollo-config-server/apollo-configservice.jar
8$ mv ./deploy/apollo-admin-server/apollo-adminservice-1.4.0.jar   ./deploy/apollo-admin-server/apollo-adminservice.jar
9$ mv ./deploy/apollo-portal-server/apollo-portal-1.4.0.jar        ./deploy/apollo-portal-server/apollo-portal.jar

六、构建 Docker 镜像

 1#构建 alpine 镜像
 2$ docker build -t alpine-bash:3.8            ./deploy/alpine-bash-3.8-image
 3
 4#构建 config-service 镜像
 5$ docker build -t apollo-config-server:v1.4.0 ./deploy/apollo-config-server
 6
 7#构建 admin-server
 8$ docker build -t apollo-admin-server:v1.4.0  ./deploy/apollo-admin-server
 9
10#构建 portal 镜像
11$ docker build -t apollo-portal-server:v1.4.0 ./deploy/apollo-portal-server

七、推送镜像到镜像仓库

推送镜像到镜像仓库，方便在 Kubernetes 中部署应用。

 1#打标签
 2$ docker tag alpine-bash:3.8             mydlqclub/alpine-bash:3.8
 3$ docker tag apollo-config-server:v1.4.0 mydlqclub/apollo-config-server:v1.4.0
 4$ docker tag apollo-admin-server:v1.4.0  mydlqclub/apollo-admin-server:v1.4.0
 5$ docker tag apollo-portal-server:v1.4.0 mydlqclub/apollo-portal-server:v1.4.0
 6
 7#推送镜像到镜像仓库
 8$ docker push mydlqclub/alpine-bash:3.8
 9$ docker push mydlqclub/apollo-config-server:v1.4.0
10$ docker push mydlqclub/apollo-admin-server:v1.4.0
11$ docker push mydlqclub/apollo-portal-server:v1.4.0

八、Kubernetes 中部署 Mysql

部署 Mysql 数据库

创建 Mysql 的 PV/PVC 存储资源，这里是通过静态方式创建 PV 与 PVC 绑定，用的是 NFS 存储，创建 PV 时需要指定 NFS Server 地址。

mysql-storage.yaml

 1apiVersion: v1
 2kind: PersistentVolume
 3metadata:
 4  name: mysql-pv
 5  labels:
 6    app: mysql-pv
 7spec:
 8  accessModes:       
 9    - ReadWriteOnce
10  capacity:          
11    storage: 5Gi
12  mountOptions:   #NFS挂在选项
13    - hard  
14    - nfsvers=4
15  nfs:            #NFS设置
16    server: 192.168.2.11    #替换nfs服务器地址
17    path: /nfs/data/mysql   #替换nfs存储目录
18---
19kind: PersistentVolumeClaim
20apiVersion: v1
21metadata:
22  name: mysql-pvc
23spec:
24  accessModes:
25    - ReadWriteOnce
26  resources:
27    requests:
28      storage: 5Gi  #设置大小为5G
29  selector:
30    matchLabels:
31      app: mysql-pv

创建 Mysql 的配置文件，注意，配置文件中一定要设置最大连接数参数，否则 Apollo 启动时连接池会创建大量与 Mysql 的连接，如果设置最大连接数太小，很可能导致 Apollo 重启。

 1kind: ConfigMap
 2apiVersion: v1
 3metadata:
 4  name: mysql-config
 5  labels:
 6    app: mysql
 7data:
 8  my.cnf: |-
 9    [client]
10    default-character-set=utf8mb4
11    [mysqld] 
12    max_connections = 2000

创建 Service 与 Deployment 部署文件

mysql-deploy.yaml

 1apiVersion: v1
 2kind: Service
 3metadata:
 4  name: mysql
 5  labels:
 6    app: mysql
 7spec:
 8  type: NodePort
 9  ports:
10  - name: mysql
11    port: 3306
12    targetPort: 3306
13    nodePort: 30336
14  selector:
15    app: mysql
16---
17apiVersion: apps/v1
18kind: Deployment

37        ports:
38        - name: mysql
39          containerPort: 3306
40        env:
41        - name: MYSQL_ROOT_PASSWORD     #root用户密码
42          value: "123456"
43        resources:
44          limits:
45            cpu: 1000m
46            memory: 512Mi
47          requests:
48            cpu: 100m
49            memory: 256Mi
50        livenessProbe:        #活性探针
51          initialDelaySeconds: 30
52          periodSeconds: 10
53          timeoutSeconds: 5
54          successThreshold: 1

58        readinessProbe:       #就绪探针
59          initialDelaySeconds: 10
60          periodSeconds: 10
61          timeoutSeconds: 5
62          successThreshold: 1
63          failureThreshold: 3
64          exec:
65            command: ["mysqladmin", "-uroot", "-p${MYSQL_ROOT_PASSWORD}", "ping"]
66        volumeMounts:
67        - name: data
68          mountPath: /var/lib/mysql
69        - name: config
70          mountPath: /etc/mysql/my.cnf
71          subPath: my.cnf  
72      volumes:
73      - name: data
74        persistentVolumeClaim:
75          claimName: mysql-pvc    #绑定上面创建的 PVC
76      - name: config      
77        configMap:
78          name: mysql-config       #使用 ConfigMap 中的 Mysql 配置

kubernetes 集群部署 Mysql

-n：指定应用在 Kubernetes 中部署的 Namespace

1# 部署存储
2$ kubectl apply -f mysql-storage.yaml -n mydlqclub
3
4# 部署 Mysql
5$ kubectl apply -f mysql-deploy.yaml -n mydlqclub

导入 SQL 文件

进入 sources/apollo-1.4.0/scripts/apollo-on-kubernetes/db 文件夹下，内容如下：

 1.
 2├── config-db-dev
 3│    └── apolloconfigdb.sql
 4├── config-db-prod
 5│    └── apolloconfigdb.sql
 6├── config-db-test-alpha
 7│    └── apolloconfigdb.sql
 8├── config-db-test-beta
 9│    └── apolloconfigdb.sql
10└── portal-db
11     └── apolloportaldb.sql

将 config-db-dev、config-db-prod 与 portal-db 目录下的 sql 文件导入上面创建的数据库中。

九、Kubernetes 中部署 Apollo

注意：请把下面所有的 mydlqcloud 为本人部署 Apollo 的 Namespace，所以这里要将全部的 mydlqcloud 改成你做自己要部署 Apollo 的 Kubernetes 中 Namespace 名称。另一个就是，部署前确保数据库中已经导入 SQL 文件，否则会就绪探针探活失败错误。

1、部署 Dev 环境 Apollo 组件

（1）、apollo-config-server-dev 部署文件

apollo-config-server-dev.yaml

（3）、kubernetes 部署 Dev 环境的 admin、config

-n：指定应用在 Kubernetes 中部署的 Namespace

1# 部署 apollo-config-server-prod
2$ kubectl apply -f apollo-config-server-prod.yaml -n mydlqclub
3
4# 部署 appllp-admin-server-prod
5$ kubectl apply -f appllp-admin-server-prod.yaml -n mydlqclub

3、部署 Apollo Portal

（1）、service-apollo-portal-server 部署文件

下面是 Portal 的部署文件，里面有个初始化镜像，是用于进行检测 Config Server、Admin Server 是否正常启动。这里需要注意，如果你上面只部署了 DEV 环境，那么请看部署文件中的注释，删除 Pro 环境的检测配置，否则服务将不能正常启动。

service-apollo-portal-server.yaml

 1# Configmap 中配置要使用的环境，这里只用 DEV 与 PRO 两个环境， 注意修改下面的参数中的 Namespace

（2）、kubernetes 部署 Apollo Portal

-n：指定应用在 Kubernetes 中部署的 Namespace

1$ kubectl apply -f service-apollo-portal-server.yaml -n mydlqclub

十、访问 Apollo Portal 界面

本人 Kubernetes 集群地址为 192.168.2.11，并且刚刚创建 Portal 时候配置的 Service 设置的 NodePort 端口为 30011，所以这里输入地址：http://192.168.2.11:30011 访问 Apollo Portal 界面，进入 Apollo 配置中心。
