linux安装Tomcat

1、官网链接：https://tomcat.apache.org/download-80.cgi
自行选择需要的包

tomcat、jdk兼容性对照表

安装

#上传文件至服务器
rz
#解压
tar -zxvf apache-tomcat-9.0.76
#配置系统变量
vim /ect/profile
#添加变量
export TOMCAT_HOME=/root/tools/tomcat/apache-tomcat-9.0.76
#使文件生效
source /etc/profile

浏览器进入 http://ip:8080
但发现无法进入，解决方案如下：
1、使用服务器的话，需要在服务器上增加8080端口

2、在firewalld 上开放8080端口
输入命令：firewall-cmd --zone=public --add-port=8080/tcp --permanent
3、重启防火墙
输入命令：firewall-cmd --reload
4、打开外部浏览器，输入http://IP:8080

其他防火墙相关命令：

查看防火墙状态： systemctl status firewalld 或者 systemctl is-active firewalld
启动防火墙： systemctl start firewalld
停止防火墙： systemctl stop firewalld
永久停用： systemctl disable firewalld
启用防火墙： systemctl enable firewalld

一台服务器上部署多个tomcat，需要在配置中增加对应的端口

进入tomcat/conf
输入命令：vim server.xml

#server.xml

    
<?xml version="1.0" encoding="UTF-8"?>

<Server port="8005" shutdown="SHUTDOWN">
  <Listener className="org.apache.catalina.startup.VersionLoggerListener" />

    <Engine name="Catalina" defaultHost="localhost">
      <Realm className="org.apache.catalina.realm.LockOutRealm">
        <Realm className="org.apache.catalina.realm.UserDatabaseRealm"

               pattern="%h %l %u %t "%r" %s %b" />
      </Host>
    </Engine>
  </Service>

    
#新加的端口配置，复制以后修改port参数就行
