Windows编辑环境变量实在麻烦，干脆用Ubuntu apt解决

1.检查是否安装好jdk

java -version

如果出现：

![已安装][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDMwMjk5OQ_size_16_color_FFFFFF_t_70]

说明已经安装好jdk

若果没有，则输入：

sudo apt-get install default-jdk

sudo apt-get install default-jre

安装完毕之后即可，不需要配置JAVA\_HOME等路径

2.下载tomcat

[http://tomcat.apache.org/][http_tomcat.apache.org]

这里我下载的是9.0.30版本的

![选择下载9.0.30版本][9.0.30]

下载Core tar.gz的

![下载.tar.gz格式的][.tar.gz]

下载完毕之后将文件提取到一个目录，我提取到了用户目录

![提取出来][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDMwMjk5OQ_size_16_color_FFFFFF_t_70 1]

如图中第一个文件夹

打开terminal输入

cd ~/apache-tomcat-9.0.30/bin/

输入

vim startup.sh

在文件末尾那行之前输入

export TOMCAT_HOME=$HOME/apache-tomcat-9.0.30

保存退出，至此tomcat配置完成。

输入

./startup.sh

出现

![tomcat成功启动][tomcat]

说明启动成功

3.打开idea ultimate（学生可以使用学校邮箱申请使用）

File->New->Project->Java Enterprise

在Application Server处 New 选择Tomcat Server 点击文件夹按钮选中tomcat所在目录![选择tomcat作为Application Server][tomcat_Application Server]

![配置tomcat][tomcat 1]

OK 选中Web Application 勾选 Create web.xml![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDMwMjk5OQ_size_16_color_FFFFFF_t_70 2][]

NEXT 命名项目为ServletTest

直接Build，成功

但是Run时候会出现

Error running 'Tomcat 9.0.8': Error copying configuration files from /usr/tomcat/conf/Catalina/localhost

的错误，这是因为访问文件夹的权限不够

打开terminal，输入

cd /home/你的用户名/apache-tomcat-9.0.30/conf/Catalina/

sudo chmod 777 *

再次运行可能会出现端口占用的问题，这是因为之前已经在8080端口开启了tomcat服务

回到idea，Run->Edit Configurations

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDMwMjk5OQ_size_16_color_FFFFFF_t_70 3][]

将Tomcat Server Settings处的 HTTP port改成8081（非8080）即可运行

运行结果：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDMwMjk5OQ_size_16_color_FFFFFF_t_70 4][]
