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

img

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

img

  • 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

img

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

    ################################################################
    ##
    ## The heap size is automatically configured by Elasticsearch

    ## required, it should be done through a file in jvm.options.d,
    ## and the min and max should be set to the same value. For
    ## example, to set the heap to 4 GB, create a new file in the
    ## jvm.options.d directory containing these lines:
    ##
    ## -Xms4g
    ## -Xmx4g

  • 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

image-20220421163207455

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
