k8s安装部署apollo配置中心

一、文章大纲

二、安装MySQL5.7
三、创建apollo-config
四、创建apollo-admin
五、创建apollo-portal
六、查看apollo各个组件服务状态
七、访问apollo
八、nginx代理配置转发#注意
一定要先启动apollo-config，再启动apollo-admin，最后启动apollo-portal

二、安装MySQL5.7

1、安装过程参考：离线安装mysql5.7_韩帅平的博客-CSDN博客

2、sql文件下载

apolloportaldb.sql​下载地址：https://github.com/nobodyiam/apollo-build-scripts/blob/master/sql/apolloportaldb.sql
apolloconfigdb.sql​下载地址：https://github.com/nobodyiam/apollo-build-scripts/blob/master/sql/apolloconfigdb.sql
#修改apolloconfigdb.sql文件
VALUES('eureka.service.url', 'default', 'http://10.96.69.115:32109/eureka/', 'Eureka服务Url，多个service以英文逗号分隔'),   #修改localhost:8080为apollo-config的Service Ip+NodePort端口，可在apollo-config服务创建好之后再修改导入库表('namespace.lock.switch', 'default', 'false', '一次发布只能有一个人修改开关'),('item.key.length.limit', 'default', '128', 'item key 最大长度限制'),('item.value.length.limit', 'default', '20000', 'item value最大长度限制'),('config-service.cache.enabled', 'default', 'false', 'ConfigService是否开启缓存，开启后能提高性能，但是会增大内存消耗！');

3、数据库内导入config、admin数据库表

mysql -u root -p

mysql> source /usr/local/apolloportaldb.sql;

三、创建apollo-config（以下是我在环境中已生成的服务yaml文件，可按需修改）

1、apollo-config-deployment.yaml文件

apiVersion: apps/v1
kind: Deployment
metadata:annotations:deployment.kubernetes.io/revision: "2"creationTimestamp: "2023-04-19T08:38:44Z"generation: 2labels:appName: apolloname: apollo-confignamespace: apollo

四、创建apollo-admin

1、apollo-admin-deployment.yaml文件

六、查看Apollo各个服务组件状态

kubectl get pods,svc,deployment -n apollo -o wide | grep apollopod/apollo-admin-946b849fc-t77jj                      1/1     Running            0          21h     172.26.20.166    IP   <none>           <none>
pod/apollo-config-547c79c5d6-nrdns                    1/1     Running            0          21h     172.26.20.190    IP   <none>           <none>
pod/apollo-portal-9694d748c-4mzpq                     1/1     Running            0          21h     172.26.20.182    IP   <none>           <none>
service/apollo-admin                     NodePort    10.96.178.0     <none>        32108:32108/TCP              22h     name=apollo-admin
service/apollo-config                    NodePort    10.96.69.115    <none>        32109:32109/TCP              22h     name=apollo-config
service/apollo-portal                    NodePort    10.96.210.42    <none>        32115:32110/TCP              22h     name=apollo-portal
deployment.apps/apollo-admin                        1/1     1            1           22h     apollo-admin                     apolloconfig/apollo-adminservice:latest                          name=apollo-admin
deployment.apps/apollo-config                       1/1     1            1           22h     apollo-config                    apolloconfig/apollo-configservice:latest                         name=apollo-config
deployment.apps/apollo-portal                       1/1     1            1           22h     apollo-portal                    apolloconfig/apollo-portal:latest                                name=apollo-portal

七、访问apollo，网址：http://IP:32110/

1、apollo前端页面，默认账号密码：apollo/admin

八、nginx代理配置转发

1、内网可通过nginx代理暴露服务，conf文件配置如下：

upstream nodes2.apollo-portal {server IP:32110;server IP:32110;server IP:32110;server IP:32110;server IP:32110;server IP:32110;server IP:32110;server IP:32110;server IP:32110;server IP:32110;
}   location / {proxy_pass http://nodes2.apollo-portal/;proxy_http_version 1.1;proxy_redirect off;proxy_set_header Host $http_host;proxy_set_header X-Real-IP $remote_addr;proxy_set_header X-Forwarded-For $remote_addr;proxy_set_header X-Forwarded-Port 80;proxy_set_header Upgrade $http_upgrade;proxy_set_header Connection "upgrade";limit_conn one 10000;limit_rate 40960k;}
