【转载】Centos 7 yum安装tomcat 命令：

系统环境
CentOS Linux release 7.2.1511 (Core)

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

2、安装wget

[root@ecs-19cb ~]# yum install -y wget

3、确认是否安装成功

1[root@ecs-19cb ~]# rpm -qa | grep wget
2wget-1.14-15.el7_4.1.x86_64

4、wget下载

1[root@ecs-19cb ~]# wget http://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-9/v9.0.17/bin/apache-tomcat-9.0.17.tar.gz
2[root@ecs-19cb ~]# ll
3total 9272
4-rw-r--r-- 1 root root 9471519 Jan 19 04:03 apache-tomcat-9.0.4.tar.gz

5、选择yum安装tomcat需要的jdk，就不用再手动配置环境变量。

[root@ecs-19cb ~]# yum -y install java-1.8*

6、查看版本

1[root@ecs-19cb ~]# java -version
2openjdk version "1.8.0_161"
3OpenJDK Runtime Environment (build 1.8.0_161-b14)
4OpenJDK 64-Bit Server VM (build 25.161-b14, mixed mode)

二、解压并启动：
1、解压

1[root@ecs-19cb ~]# tar -zxvf apache-tomcat-9.0.4.tar.gz 
2[root@ecs-19cb ~]# ll
3total 9276
4drwxr-xr-x 9 root root 4096 Feb 3 13:59 apache-tomcat-9.0.4
5-rw-r--r-- 1 root root 9471519 Jan 19 04:03 apache-tomcat-9.0.4.tar.gz

2、启动tomcat，显示tomcat started就是成功启动

1[root@ecs-19cb ~]# ll
2total 9276
3drwxr-xr-x 9 root root 4096 Feb 3 13:59 apache-tomcat-9.0.4
4-rw-r--r-- 1 root root 9471519 Jan 19 04:03 apache-tomcat-9.0.4.tar.gz
5[root@ecs-19cb ~]# cd apache-tomcat-9.0.4/
6[root@ecs-19cb apache-tomcat-9.0.4]# ./bin/startup.sh 
7Using CATALINA_BASE: /root/apache-tomcat-9.0.4
8Using CATALINA_HOME: /root/apache-tomcat-9.0.4
9Using CATALINA_TMPDIR: /root/apache-tomcat-9.0.4/temp
10Using JRE_HOME: /usr
11Using CLASSPATH: /root/apache-tomcat-9.0.4/bin/bootstrap.jar:/root/apache-tomcat-9.0.4/bin/tomcat-juli.jar
12Tomcat started.

3、关闭防火墙

1[root@ecs-19cb etc]# systemctl stop firewalld
2[root@ecs-19cb etc]# systemctl status firewalld
3● firewalld.service - firewalld - dynamic firewall daemon
4Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
5Active: inactive (dead)
6Docs: man:firewalld(1)

4、查看tomcat默认端口8080是否开启

1[root@ecs-19cb ~]# netstat -ntlp
2Active Internet connections (only servers)
3Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name 
4tcp 0 0 0.0.0.0:111 0.0.0.0:* LISTEN 1/systemd 
5tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 1528/sshd 
6tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN 1123/master 
7tcp 0 0 127.0.0.1:32001 0.0.0.0:* LISTEN 1541/java 
8tcp6 0 0 :::8009 :::* LISTEN 11809/java 
9tcp6 0 0 :::111 :::* LISTEN 1/systemd 
10tcp6 0 0 :::8080 :::* LISTEN 11809/java 
11tcp6 0 0 :::22 :::* LISTEN 1528/sshd 
12tcp6 0 0 ::1:25 :::* LISTEN 1123/master 
13tcp6 0 0 127.0.0.1:8005 :::* LISTEN 11809/java

三、浏览器打开：http://ip:8080

Centos 7 firewall 命令：

查看已经开放的端口：

firewall-cmd --list-ports

开启端口

firewall-cmd --zone=public --add-port=80/tcp --permanent

命令含义：

–zone #作用域

–add-port=80/tcp #添加端口，格式为：端口/通讯协议

–permanent #永久生效，没有此参数重启后失效

重启防火墙

1firewall-cmd --reload #重启firewall
2systemctl stop firewalld.service #停止firewall
3systemctl disable firewalld.service #禁止firewall开机启动
4firewall-cmd --state #查看默认防火墙状态（关闭后显示notrunning，开启后显示running）
