1、租户系统实战
2、中间件实战
应用部署需要关注的信息【应用部署三要素】
-
应用的部署方式
-
应用的数据挂载(数据,配置文件)
-
应用的可访问性
2.1、部署mysql
a、mysql容器启动
docker run -p 3306:3306 --name mysql-01 \
-v /mydata/mysql/log:/var/log/mysql \
-v /mydata/mysql/data:/var/lib/mysql \
-v /mydata/mysql/conf:/etc/mysql/conf.d \
-e MYSQL_ROOT_PASSWORD=root \
--restart=always \
-d mysql:5.7
b、mysql配置示例
[client]
default-character-set=utf8mb4
[mysql]
default-character-set=utf8mb4
[mysqld]
init_connect='SET collation_connection = utf8mb4_unicode_ci'
init_connect='SET NAMES utf8mb4'
character-set-server=utf8mb4
collation-server=utf8mb4_unicode_ci
skip-character-set-client-handshake
skip-name-resolve
c、mysql部署分析
- 集群内部,直接通过应用的 【服务名.项目名】 直接访问
mysql -uroot -hhis-mysql-glgf.his -p
- 集群外部。服务中指定工作复制,Nodeport中暴露
2.2、部署Redis
a、redis容器启动
#创建配置文件
## 1、准备redis配置文件内容
mkdir -p /mydata/redis/conf && vim /mydata/redis/conf/redis.conf
##配置示例
appendonly yes
port 6379
bind 0.0.0.0
#docker启动redis
docker run -d -p 6379:6379 --restart=always \
-v /mydata/redis/conf/redis.conf:/etc/redis/redis.conf \
-v /mydata/redis-01/data:/data \
--name redis-01 redis:6.2.5 \
redis-server /etc/redis/redis.conf
c、redis部署分析
2.3、部署ElasticSearch
a、es容器启动
# 创建数据目录
mkdir -p /mydata/es-01 && chmod 777 -R /mydata/es-01
# 容器启动
docker run --restart=always -d -p 9200:9200 -p 9300:9300 \
-e "discovery.type=single-node" \
-e ES_JAVA_OPTS="-Xms512m -Xmx512m" \
-v es-config:/usr/share/elasticsearch/config \
-v /mydata/es-01/data:/usr/share/elasticsearch/data \
--name es-01 \
elasticsearch:7.13.4
b、es部署分析
注意: 子路径挂载,配置修改后,k8s不会对其Pod内的相关配置文件进行热更新,需要自己重启Pod
c、实施
-
建立配置文件
- elasticsearch.yml
cluster.name: "docker-cluster" network.host: 0.0.0.0
- jvm.options
################################################################ ## ## JVM configuration ## ################################################################ ## ## WARNING: DO NOT EDIT THIS FILE.

-
添加环境变量
-
挂载配置文件
采用子路径配置
3、部署Nacos
1、部署nacos
a、下载nacos数据库文件
https://github.com/alibaba/nacos/blob/develop/distribution/conf/nacos-mysql.sql
#2、要执行以下文件,按照要求先创库
CREATE DATABASE `nacos`;
USE nacos;

b、application.properties 文件
spring.datasource.platform=mysql
db.num=1
db.url.0=jdbc:mysql://11.162.196.16:3306/nacos?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true
db.user=nacos_devtest
db.password=youdontknow
c、cluster.conf
自行修改配置
#it is ip
#example
nacos-v1-0.his-nacos.svc.cluster.local:8848
nacos-v1-1.his-nacos.svc.cluster.local:8848
nacos-v1-2.his-nacos.svc.cluster.local:8848
镜像名+dns+svc.cluster.local【固定写法】
d、挂载配置文件
其中 application.properties 挂载到:/home/nacos/conf/application.properties
cluster.conf 挂载到:/home/nacos/conf/cluster.conf
4、应用商店
4.1、镜像下载从商店
自行选择
4.2、应用仓库
使用企业空间管理员登录,设置应用仓库
企业空间—》应用管理—》应用仓库
常用的仓库:https://charts.bitnami.com/bitnami
5、云部署
5.1、上云优化
- 每个微服务准备
bootstrap.properties
,配置 nacos地址信息。默认使用本地 - 2、每个微服务准备Dockerfile,启动命令,指定线上nacos配置等。
- 3、每个微服务制作自己镜像。
5.2、Dockerfile
FROM openjdk:8-jdk
LABEL maintainer=leifengyang
#docker run -e PARAMS="--server.port 9090"
ENV PARAMS="--server.port=8080 --spring.profiles.active=prod --spring.cloud.nacos.discovery.server-addr=his-nacos.his:8848 --spring.cloud.nacos.config.server-addr=his-nacos.his:8848 --spring.cloud.nacos.config.namespace=prod --spring.cloud.nacos.config.file-extension=yml"
RUN /bin/cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime && echo 'Asia/Shanghai' >/etc/timezone
COPY target/*.jar /app.jar
EXPOSE 8080
#
ENTRYPOINT ["/bin/sh","-c","java -Dfile.encoding=utf8 -Djava.security.egd=file:/dev/./urandom -jar app.jar ${PARAMS}"]
规则:
1、容器默认以8080端口启动
2、时间为CST
3、环境变量 PARAMS 可以动态指定配置文件中任意的值
4、nacos集群内地址为 his-nacos.his:8848
5、微服务默认启动加载 nacos中 服务名-激活的环境.yml
文件,所以线上的配置可以全部写在nacos中。
5.3、推送镜像给阿里云
- 开通阿里云“容器镜像服务(个人版)”
- 创建一个名称空间。(存储镜像)
- 推送镜像到阿里云镜像仓库
$ docker login --username=forsum**** registry.cn-hangzhou.aliyuncs.com
#把本地镜像,改名,成符合阿里云名字规范的镜像。
$ docker tag [ImageId] registry.cn-hangzhou.aliyuncs.com/lfy_ruoyi/镜像名:[镜像版本号]
## docker tag 461955fe1e57 registry.cn-hangzhou.aliyuncs.com/lfy_ruoyi/ruoyi-visual-monitor:v1
$ docker push registry.cn-hangzhou.aliyuncs.com/lfy_ruoyi/镜像名:[镜像版本号]
## docker push registry.cn-hangzhou.aliyuncs.com/lfy_ruoyi/ruoyi-visual-monitor:v1
5.4、前端打包
npm run build:prod
