Centos7 yum安装tomcat

以下操作是在线安装apache-tomcat 需要联网下载包。

liux系统环境

[root@localhost ~]# cat /etc/redhat-release 

　CentOS Linux release 7.6.1810 (Core)

一、环境搭建准备
1、先到tomcat官网https://tomcat.apache.org/查看下载路径

我下载的tomcat-8.5.37 如： http://mirrors.shu.edu.cn/apache/tomcat/tomcat-8/v8.5.37/bin/apache-tomcat-8.5.37.tar.gz

2、安装wget

[root@localhost ~]# yum install -y wget

3、确认是否安装成功

[root@localhost ~]# rpm -qa | grep wget

wget-1.14-18.el7.x86_64

4、wget下载安装包

[root@localhost ~]# wget http://mirrors.shu.edu.cn/apache/tomcat/tomcat-8/v8.5.37/bin/apache-tomcat-8.5.37.tar.gz

[root@localhost ~]# lls

#在文件中发现此包

#-rw-r--r--. 1 root root 9653382 12月 12 21:00 apache-tomcat-8.5.37.tar.gz

5、选择yum安装tomcat需要的jdk-1.8，就不用再手动配置环境变量。

[root@localhost ~]# yum -y install java-1.8*

6、查看JDK版本

[root@localhost ~]# java -version

openjdk version "1.8.0_191"
 OpenJDK Runtime Environment (build 1.8.0_191-b12)
 OpenJDK 64-Bit Server VM (build 25.191-b12, mixed mode)

二、解压并启动
1、解压

[root@localhost ~]# tar -zxvf apache-tomcat-8.5..tar.gz

　[root@localhost ~]# ll

　# 总用量 9436

#drwxr-xr-x. 9 root root 220 1月 2 15:08 apache-tomcat-8.5.37

2、启动tomcat，显示tomcat started就是成功启动    启动- startup.sh    停止-shutdown.sh

　[root@localhost ~]# cd apache-tomcat-8.5.37

[root@localhost apache-tomcat-8.5.]# ./bin/startup.sh

Using CATALINA_BASE: /root/apache-tomcat-8.5.37
  Using CATALINA_HOME: /root/apache-tomcat-8.5.37
  Using CATALINA_TMPDIR: /root/apache-tomcat-8.5.37/temp
  Using JRE_HOME: /usr
  Using CLASSPATH: /root/apache-tomcat-8.5.37/bin/bootstrap.jar:/root/apache-tomcat-8.5.37/bin/tomcat-juli.jar
  Tomcat started.

3、关闭防火墙

[root@localhost ~]# systemctl stop firewalld    #关闭防火墙
[root@localhost ~]# systemctl status firewalld  #查看状态

[root@localhost ~]# systemctl disable firewalld    #开机自动关闭

firewalld.service - firewalld - dynamic firewall daemon
Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
Active: inactive (dead)
Docs: man:firewalld()

4、查看tomcat默认端口8080是否开启

[root@localhost ~]# netstat -ntlp
