1、tomcat的安装

//安装java环境
tomcat本身是一个Java程序，所以必须要有Java的的运行状态！

qinziteng@tomcat:~$ java  Command 'java' not found, but can be installed with: sudo apt install default-jre sudo apt install openjdk-11-jre-headless sudo apt install openjdk-8-jre-headless qinziteng@tomcat:~$ sudo apt install openjdk-8-jre-headless qinziteng@tomcat:~$ java -version openjdk version "1.8.0_282" OpenJDK Runtime Environment (build 1.8.0_282-8u282-b08-0ubuntu1~18.04-b08) OpenJDK 64-Bit Server VM (build 25.282-b08, mixed mode) 

//下载对应版本tomcat包
tomcat官网：https://tomcat.apache.org/

或者使用wget下载

qinziteng@tomcat:~$ sudo wget https://downloads.apache.org/tomcat/tomcat-8/v8.5.65/bin/apache-tomcat-8.5.65.tar.gz 

下载好之后解压缩

qinziteng@tomcat:~$ tar zxf apache-tomcat-8.5.65.tar.gz qinziteng@tomcat:~$ sudo mv apache-tomcat-8.5.65 /usr/local/tomcat qinziteng@tomcat:~$ ls /usr/local/tomcat/ bin conf lib logs README.md RUNNING.txt webapps BUILDING.txt CONTRIBUTING.md LICENSE NOTICE RELEASE-NOTES temp wor 

//优化路径并开启

qinziteng@tomcat:~$ sudo ln -s /usr/local/tomcat/bin/* /usr/local/sbin/ qinziteng@tomcat:~$ startup.sh start Using CATALINA_BASE: /usr/local/tomcat Using CATALINA_HOME: /usr/local/tomcat Using CATALINA_TMPDIR: /usr/local/tomcat/temp Using JRE_HOME: /usr Using CLASSPATH: /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar Using CATALINA_OPTS: Tomcat started. qinziteng@tomcat:~$ netstat -anput | grep 8080 (Not all processes could be identified, non-owned process info will not be shown, you would have to be root to see it all.) tcp6 0 0 :::8080 :::* LISTEN 3860/java 

启动参数：

startup.sh start //启动
shutdown.sh //关闭

catalina.sh stop //启动
catalina.sh start //关闭

//关闭防火墙

qinziteng@tomcat:~$ sudo ufw disable 

浏览器访问

2、tomcat基本配置

//更改端口号

qinziteng@tomcat:~$ vim /usr/local/tomcat/conf/server.xml ....... <Connector port="8081" protocol="HTTP/1.1"  connectionTimeout="20000" redirectPort="8443" /> 

重启tomcat服务

qinziteng@tomcat:/usr/local/tomcat/bin$ shutdown.sh qinziteng@tomcat:/usr/local/tomcat/bin$ startup.sh 

//更改网站目录

qinziteng@tomcat:~$ vim /usr/local/tomcat/conf/server.xml ....... <Host name="localhost" appBase="/opt/www"  unpackWARs="true" autoDeploy="true"> 

创建网站家目录

qinziteng@tomcat:~$ sudo mkdir /opt/www/ROOT -p 

注意ROOT一定要是大写！！
重启tomcat服务

qinziteng@tomcat:/usr/local/tomcat/bin$ shutdown.sh qinziteng@tomcat:/usr/local/tomcat/bin$ startup.sh
