centos7--制作java微服务为系统服务!
2021-01-08 23:33
标签：def 构建 img exec yml server boot 系统服务 api 公司项目使用java构建,服务器使用linux--centos7,项目中使用了众多微服务快速成型,随着时间推移,xxx.jar 每次通过命令启动比较繁琐,本着轻松懒的方式,将这些服务通通制作成系统级别的服务,也就是"systemctl start service_name" ,本人使用python语言,通过python批量制作所有java服务 centos7--制作java微服务为系统服务! 标签：def 构建 img exec yml server boot 系统服务 api 原文地址：https://www.cnblogs.com/CrazySheldon1/p/12965383.html背景
