2.Tomcat
2.1 网站代码
- PHP LNMP
- Java LNMT(Tomcat/Resin/) Oracle(Weblogic)
2.2JVM
- Windows
- 我们希望 1分代码 可以运行在不同的 系统中 (代码的可移植性)
- JAVA程序 会被放在1个叫虚拟机容器
- JVM Java Virtual Machine Java 虚拟机 运行java程序：1份代码可以处处使用
2.3 JDK + TOMCAT
- JDK Java Development Kit Java程序运行环境
- TOMCAT (与nginx) 存放java程序代码
2.4 JDK + TOMCAT 环境准备
yum install -y tree vim wget bash-completion bash-completion-extras lrzsz net-tools sysstat iotop iftop htop unzip nc nmap telnet bc psmisc httpd-tools bind-utils

- catalina.out
- tomcat日志 最全的日志
- 这个日志默认会被轮询（定时切割），切割之后catalina.out日志内容不会被清空，会越来越大
- catalina.2019-07-05.log 中间是日期，catalina.out的切割日志
- localhost_access_log.2019-07-05.txt 访问日志
