Windows安装tomcat，以服务的方式管理，如何设置虚拟内存

之前工作中，部署tomcat都是使用Linux服务器，最近遇到个客户，提供的服务器是Windows server，并且需要通过服务的方式管理tomcat；以自己多年的码农经验，感觉应该没有问题，结果啪啪打脸了，遇到的核心问题是配置的虚拟内存没有生效，最终还是解决了，以下问解决方案：

1、环境及软件

Windows server 2016 Datacenter、jdk=1.8.0_181、apache-tomcat-8.5.59-windows-x64.zip

2、配置虚拟内存

jdk安装及环境配置变量、tomcat解压及配置环境变量，这就不过多描述，详细请自行百度。

2.1、使用startup.bat启动

修改bin\catalina.bat文件，在最上面添加这样一句：

set JAVA_OPTS=-Xms256m -Xmx512m

@echo off

set JAVA_OPTS=-Xms256m -Xmx512m

启动tomcat，有如下信息，说明虚拟内存设置成功。
