Linux下载安装Tomcat详解

1.官网下载对应版本：，下载 “tar.gz ”压缩包。 2.使用fianlshell工具上传至服务器并解压：

[root@iZbp1ganqt1lx0rpzog8z2Z tools]# tar -zxvf apache-tomcat-8.5.87.tar.gz -C /opt/apps

3.修改apache-tomcat-8.5.87.tar.gz名称为：tomcat-8.5方便后续操作

[root@iZbp1ganqt1lx0rpzog8z2Z tools]# mv apache-tomcat-8.5.87/ tomcat-8.5

4.切换至tomcat的bin目录下：

[root@iZbp1ganqt1lx0rpzog8z2Z tools]# cd /opt/apps/tomcat-8.5/bin

5.启动tomcat，出现一下信息表示启动成功

[root@iZbp1ganqt1lx0rpzog8z2Z bin]# ./startup.sh
Using CATALINA_BASE:   /opt/apps/tomcat-8.5
Using CATALINA_HOME:   /opt/apps/tomcat-8.5
Using CATALINA_TMPDIR: /opt/apps/tomcat-8.5/temp
Using JRE_HOME:        /usr/local/jdk1.8.0_361/jre
Using CLASSPATH:       /opt/apps/tomcat-8.5/bin/bootstrap.jar:/opt/apps/tomcat-8.5/bin/tomcat-juli.jar
Using CATALINA_OPTS:   
Tomcat started.

6.查看防火墙状态：

[root@iZbp1ganqt1lx0rpzog8z2Z ~]# systemctl status firewalld
● firewalld.service - firewalld - dynamic firewall daemon
   Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
   Active: inactive (dead)
     Docs: man:firewalld(1)

7.防火墙状态为： Active: inactive (dead)表示未启用，执行命令开启防火墙

[root@iZbp1ganqt1lx0rpzog8z2Z ~]# service firewalld start
Redirecting to /bin/systemctl start firewalld.service

在执行第六步命令，出现一下信息表示防火墙以启用：

[root@iZbp1ganqt1lx0rpzog8z2Z ~]# systemctl status firewalld
● firewalld.service - firewalld - dynamic firewall daemon
   Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
   Active: active (running) since 六 2023-03-25 15:13:39 CST; 4s ago
     Docs: man:firewalld(1)
 Main PID: 3005 (firewalld)
    Tasks: 2
   Memory: 26.1M
   CGroup: /system.slice/firewalld.service
           └─3005 /usr/bin/python2 -Es /usr/sbin/firewalld --nofork --nopid

8.查看开启端口号：一下信息表示没有端口开启

[root@iZbp1ganqt1lx0rpzog8z2Z ~]# firewall-cmd --list-all 
public
  target: default
  icmp-block-inversion: no
  interfaces: 
  sources: 
  services: dhcpv6-client ssh
  ports: 
  protocols: 
  masquerade: no
  forward-ports: 
  source-ports: 
  icmp-blocks: 
  rich rules:

9.开启端口：

[root@iZbp1ganqt1lx0rpzog8z2Z ~]# firewall-cmd --zone=public --permanent --add-port=8080/tcp
success

10.开启成功后进行刷新操作

[root@iZbp1ganqt1lx0rpzog8z2Z ~]# firewall-cmd --reload
success

再次执行第八步进行查看，出现一下信息表示操作成功

[root@iZbp1ganqt1lx0rpzog8z2Z ~]# firewall-cmd --list-all 
public
  target: default
  icmp-block-inversion: no
  interfaces: 
  sources: 
  services: dhcpv6-client ssh
  ports: 8080/tcp
  protocols: 
  masquerade: no
  forward-ports: 
  source-ports: 
  icmp-blocks: 
  rich rules:

11.访问tomcat，输入http://localhost:8080/，输入对应ip地址

①如果访问不了，进一步查看/opt/apps/tomcat-8.5/logs/catalina.out 该文件下的日志信息，出现以下信息： /opt/apps/tomcat-8.5/bin/catalina.sh:行504: /usr/local/jdk1.8.0_361/jre/bin/java: 没有那个文件或目录 ②找到/opt/apps/tomcat-8.5/bin/catalina.sh该文件进行修改，添加一下信息即可:

export JAVA_HOME=/opt/apps/jdk1.8.0_361
export JRE_HOME=/opt/apps/jdk1.8.0_361/jre
