centos利用shell脚本快速部署nacos

本教程部署的是nacos1.4.0

一、首先将nacos包与jdk存放在目录nacos_deploy

在这里插入图片描述
将该文件夹压缩打包

tar -zcvf nacos_deploy.tar.gz nacos_deploy/

然后将nacos_deploy.tar.gz上传到OSS

二、利用shell从oss拉取 并部署

}

}main

最后还要检查一下/etc/profile，用java -version看java运行环境是否正常，正常后再检查nacos的配置，然后调用nacos提供的启动脚本启动即可

三、异常退出重启处理（拓展）

如果要加上systemd，满足在异常退出，及开机重启，脚本改成以下：

  • 不再配置系统级的Java环境变量，而是改成systemd级别的。
  • 使用systemctl start nacos、systemctl status nacos、systemctl stop nacos管理
