IDEA同一项目启动多个实例

　　为了验证负载均衡，服务提供者（EurekaClientServiceProviderApplication）需要启动多个实例，当前已启动了一个实例，端口号8762：

2019-07-18 16:06:58.626  INFO [a-bootiful-client,,,] 43400 --- [           main] o.s.b.w.embedded.tomcat.TomcatWebServer  : Tomcat started on port(s): 8762 (http) with context path ''
2019-07-18 16:06:58.627  INFO [a-bootiful-client,,,] 43400 --- [           main] .s.c.n.e.s.EurekaAutoServiceRegistration : Updating port to 8762
2019-07-18 16:06:58.629  INFO [a-bootiful-client,,,] 43400 --- [           main] h.EurekaClientServiceProviderApplication : Started EurekaClientServiceProviderApplication in 7.985 seconds (JVM running for 9.474)

　　如何再启动一个呢？三板斧即可：

　　1、点开项目运行的配置编辑框

　　2、选择我们的项目，勾选Allow parallel run复选框

　　3、现在去修改application.properties的server.port为新端口8772，新实例启动了：

2019-07-18 17:00:07.374  INFO [a-bootiful-client,,,] 48872 --- [           main] o.s.b.w.embedded.tomcat.TomcatWebServer  : Tomcat started on port(s): 8772 (http) with context path ''
2019-07-18 17:00:07.376  INFO [a-bootiful-client,,,] 48872 --- [           main] .s.c.n.e.s.EurekaAutoServiceRegistration : Updating port to 8772
2019-07-18 17:00:07.378  INFO [a-bootiful-client,,,] 48872 --- [           main] h.EurekaClientServiceProviderApplication : Started EurekaClientServiceProviderApplication in 9.425 seconds (JVM running for 10.974)

　　运行框如果选择我们的项目的话，现在运行标志右下角那里会出现数字2：

　　题外话，parrellel是并行的意思。
