Automated Deployment Script: Build, Transfer, and Restart with Eureka and Nginx

Configuration Variables

Define the necessary variables for the deployment process, such as app_name=SERVICE_NAME, instance_id=serviceIP:9796, port=9796, remote_ip=172.19.38.133, Nginx IPs ( nginx_biz_1_ip=172.19.38.93, nginx_biz_2_ip=172.19.38.124), the project path ( project_path=service), the jar package name ( package=servicename-web.jar), and the release directory ( release_path=/usr/local/servicename/).

Build and Package

Compile and package the application without running tests:

mvn clean package -DskipTests=true

Transfer Package to Remote Server

Synchronize the built jar file to the target server using rsync:

rsync -av --progress ${project_path}/target/${package} root@${remote_ip}:/data/jenkins/package/

Take Nginx Services Offline

Log the shutdown and execute the Nginx service‑down scripts for both business instances:

echo "nginx_biz_1服务下线"

/data/script/nginx/nginx-service-down.sh ${nginx_biz_1_ip} ${remote_ip} ${port}

/data/script/nginx/nginx-remote-nginx-reload.sh ${nginx_biz_1_ip}

echo "nginx_biz_2服务下线"

/data/script/nginx/nginx-service-down.sh ${nginx_biz_2_ip} ${remote_ip} ${port}

/data/script/nginx/nginx-remote-nginx-reload.sh ${nginx_biz_2_ip}

Take Eureka Service Offline

Log the action and invoke the Python script to deregister the instance from Eureka:

echo "eureka服务下线"

python3 /data/script/eureka_biz_out_of_service-eureka.py ${app_name} ${instance_id}

sleep 35s

Restart Service on Remote Host

Copy the new jar to the release directory and restart the service via SSH:

ssh root@${remote_ip} "source /etc/profile && /usr/bin/cp -p /data/jenkins/package/${package} ${release_path} && ${release_path}web.sh restart"

echo "正在重启服务，等待40s"

sleep 40s

Health Check

Run a Python HTTP‑code check to verify the service is reachable:

python3 /usr/local/script/check_http_code.py ${remote_ip} ${port} ${app_name}

Bring Eureka Service Back Online

Log the action and re‑register the instance with Eureka:

echo "eureka服务上线"

python3 /usr/local/script/eureka_biz_up-eureka.py ${app_name} ${instance_id}

Bring Nginx Services Back Online

Log and start each Nginx business instance, then reload the remote Nginx configuration:

echo "nginx_biz_1服务上线"

/data/script/nginx/xlm-service-up.sh ${nginx_biz_1_ip} ${remote_ip} ${port}

/data/script/nginx/xlm-remote-nginx-reload.sh ${nginx_biz_1_ip}

echo "nginx_biz_2服务上线"

/data/script/nginx/xlm-service-up.sh ${nginx_biz_2_ip} ${remote_ip} ${port}

/data/script/nginx/xlm-remote-nginx-reload.sh ${nginx_biz_2_ip}
