# 后端应用编译和部署
#### 部署后端应用
1. **上传代码**
   
   Git代码提交：checkout空的华为代码仓库到本地，然后将代码复制到本地目录，先然后Add 然后commit 最后push
   
   
2. **修改编译命令**
   
   ```
   mvn clean install -U -pl ieo-4a/ieo-4a-biz  -am  -DskipTests=true -Pdev
   ```
   
   
   
3. **修改dockerfile**
   
   基础镜像地址、APM探针检查
   ```
   FROM swr.cn-east-3.myhuaweicloud.com/group-dev/java:8-jre
   MAINTAINER ieo@dtt.com
   ENV TZ=Asia/Shanghai
   ENV JAVA_OPTS="-Xms512m -Xmx1024m -Djava.security.egd=file:/dev/./urandom"
   RUN ln -sf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone && \
       mkdir -p /ieo-4a && \
       cd /ieo-4a && \
       curl -k https://apm2-javaagent-cn-east-3.obs.cn-east-3.myhuaweicloud.com/apm_agent_install.sh -o apm_agent_install.sh && bash apm_agent_install.sh -ak tqef3mryJ45BhrRc -sk Ts66kLf8uLlGMbDlTmYZSvtMiqjIxmx8YIbgyTY4dLTkM4CrBbtfF1OcWmPX7Kg6V0C7PM68BcGY6yF7DVzTTpRS6GCI4ToIEMRd7W1nRg9Zn4voROoKX903tvYyCXxQqhrdA4pOrOaBwo2OFTjWTafiyrwsOPrE3RUEoViQSXW3XMv38nGRAPZkVO084EZt6WhfwMjuSznv2wngh2qMmbIMUqgbYGzALa73oL2kUabX3SFw0E1i0IzbANAtsVyl -masteraddress https://100.125.4.27:41333 -obsaddress https://apm2-javaagent-cn-east-3.obs.cn-east-3.myhuaweicloud.com -version latest
   WORKDIR /ieo-4a
   EXPOSE 4000
   ADD ./ieo-4a/ieo-4a-biz/target/ieo-4a-biz.jar ./
   CMD sleep 2;java -javaagent:/ieo-4a/apm-javaagent/apm-javaagent.jar=appName=ieo-4a,env=dev $JAVA_OPTS -Dlog4j2.formatMsgNoLookups=true -jar ieo-4a-biz.jar
   ```
   
   
   
4. **配置部署Secret**
   
   yaml-secret=default-secret（可以先用kubectl get secret -n d-fsc）

5. **修改pom.xml中的私服地址**
   
   ```
   /pom.xml
   <distributionManagement>
      <repository>
         <id>nexus-releases</id>
         <name>nexus-releases</name>
         <url>http://xx.xx.xx.xx:8081/repository/maven-releases/</url>
      </repository>
      <snapshotRepository>
         <id>nexus-snapshots</id>
         <name>nexus-snapshots</name>
         <url>http://xxx.xxx.xxx.xxx:8081/repository/maven-snapshots/</url>
      </snapshotRepository>
   </distributionManagement>
   ```
   
   
6. **修改配置中心的相关配置**

7. **后端应用CI流水线**
   
   ```
   ieo-4a-构建镜像
   mvn clean install -U -pl ieo-4a/ieo-4a-biz  -am  -DskipTests=true -Pdev
   http://xx.xx.xx.xx:8081/repository/maven-releases/          release
   http://xx.xx.xx.xx:8081/repository/maven-snapshots/           snapshot
   http://xx.xx.xx.xx:8081/repository/maven-public/          release
   ./ieo-4a/ieo-4a-biz/target/*.jar
   env_dev
   ieo-4a
   v1.1
   ./ieo-4a/ieo-4a-biz/Dockerfile
   ```

9. **后端应用访问**
   
   nodePort暴露服务 安全组放开端口

10. **启动顺序**
    
    4a启动成功后检查redis是否有gl开头的key， 如果有则启动gateway
    ```
    nacos -> 4a -> auth -> gateway
    ```
