Before you read this document, you need to complete some preparations before deploying Shenyu according to the Deployment Prerequisites document.

This aritcle introduces how to delopy the Shenyu gateway in cluster enviroment.

In this part, you can see ShenYu Binary Packages Deployment before deploying.

Enviromental Preparation

• Two or more Gateway Boostrap servers, these servers must install JDK1.8+.
• A server for Gateway Admin, this server must install mysql/pgsql/h2 and JDK1.8+.
• A server for nginx.

Start Apache ShenYu Admin

• download and unzip apache-shenyu-${current.version}-admin-bin.tar.gz in your Gateway Admin server.

• config your database, go to the /conf directory, and modify spring.profiles.active of the configuration in application.yaml to mysql, pg or h2.

• config your way of synchronization, go to the /conf directory, and modify shenyu.sync of configuration in application.yaml to websocket, http, zookeeper, etcd, consul or nacos.

• start Apache ShenYu Admin in bin directory.

> windows: start.bat 

> linux: ./start.sh 

Start Apache ShenYu Boostrap

• download and unzip apache-shenyu-${current.version}-bootstrap-bin.tar.gz in your Gateway Boostrap server.

• config your synchronization, go to the /conf directory, and modify shenyu.sync of configuration in application.yaml to websocket, http, zookeeper, etcd, consul or nacos, this configuaration must remain the same of ShenyYu Admin.

• repeat above-mentioned operations in each ShenYu Bootstrap server.

• start Apache ShenYu Bootstrap in bin directory.

> windwos : start.bat 

> linux : ./start.sh 

After completing these operations, you will deploy ShenYu Boostrap Cluster.

For example. you will deploy ShenYu Bootstrap in 10.1.1.1 and 10.1.1.2 and deploy nginx in 10.1.1.3.

Start Nginx

• download and install nginx.

• modify upstream and server of configuration in nginx.conf.

upstream shenyu_gateway_cluster {
  ip_hash;
  server 10.1.1.1:9195 max_fails=3 fail_timeout=10s weight=50;
  server 10.1.1.2:9195 max_fails=3 fail_timeout=10s weight=50;
}

server {
  listen 9195;
  location / {
		proxy_pass http://shenyu_gateway_cluster;
		proxy_set_header HOST $host;
		proxy_read_timeout 10s;
		proxy_connect_timeout 10s;
  }
}

• start nginx.

> windows: ./nginx.exe

> linux: /usr/local/nginx/sbin/nginx 

• verify nginx, looking at your ShenYu Bootstrap log or Nginx log, Where will the verification request go.
