Tomcat7 在 Ubuntu 14.04 x64 上启动得太晚了 [Digitalocean]
2022-08-31 20:50:17
我正在使用digitalocean，并试图在ubuntu上安装和启动tomcat，但不幸的是我无法做到这一点。（创建了新的液滴并尝试了10次）
1GB 内存 30GB SSD 磁盘 阿姆斯特丹 2 Ubuntu 14.04 x64
当我开始tomcat时，它说“Tomcat开始了”。但我无法从浏览器访问页面。和 ./shutdown.sh 返回错误。
可能是什么问题？
我现在注意到了一些事情。当我写这个问题时，显示tomcat页面。显示页面花了 28 分钟
catalina.out 说： 信息： 使用 [SHA1PRNG] 创建用于会话 ID 生成的 SecureRandom 实例需要 [1，718，769] 毫秒。
以下是我的安装步骤（这些步骤适用于不同的vps，但不适用于数字海洋液滴）：
Install oracle jdk
