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 offset JAVA_OPTS=-Xms256m -Xmx512mrem Licensed to the Apache Software Foundation (ASF) under one or more

启动tomcat,有如下信息,说明虚拟内存设置成功。
2.2、使用服务的方式启动
首先、将tomcat安装成系统服务,打开cmd,使用超级管理员权限,执行命令:service.bat install
打开系统服务,可以看到已经注册成功的tomcat服务
启动服务,并查看日志(位置:logs\catalina.2024-03-26.log)
通过日志发现,我们在catalina.bat文件中,配置的虚拟内存没有生效;解决方案,打开bin\tomcat8w.exe程序(前提条件,必须将tomcat注册成系统服务)
将默认的最小和最大内存调整成256和512,然后重启服务,并查看日志
到这里,核心问题就解决了
