【轉載】Centos 7 yum安裝tomcat 命令：
系統環境
CentOS Linux release 7.2.1511 (Core)
一、搭建准備：
1、先到tomcat官網https://tomcat.apache.org/查看下載路徑
2、安裝wget
[root@ecs-19cb ~]# yum install -y wget
3、確認是否安裝成功
[root@ecs-19cb ~]# rpm -qa | grep wget wget-1.14-15.el7_4.1.x86_64
4、wget下載
[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 [root@ecs-19cb ~]# ll total 9272 -rw-r--r-- 1 root root 9471519 Jan 19 04:03 apache-tomcat-9.0.4.tar.gz
5、選擇yum安裝tomcat需要的jdk，就不用再手動配置環境變量。
[root@ecs-19cb ~]# yum -y install java-1.8*
6、查看版本
[root@ecs-19cb ~]# java -version openjdk version "1.8.0_161" OpenJDK Runtime Environment (build 1.8.0_161-b14) OpenJDK 64-Bit Server VM (build 25.161-b14, mixed mode)
二、解壓並啟動：
1、解壓
[root@ecs-19cb ~]# tar -zxvf apache-tomcat-9.0.4.tar.gz [root@ecs-19cb ~]# ll total 9276 drwxr-xr-x 9 root root 4096 Feb 3 13:59 apache-tomcat-9.0.4 -rw-r--r-- 1 root root 9471519 Jan 19 04:03 apache-tomcat-9.0.4.tar.gz
2、啟動tomcat，顯示tomcat started就是成功啟動
[root@ecs-19cb ~]# ll total 9276 drwxr-xr-x 9 root root 4096 Feb 3 13:59 apache-tomcat-9.0.4 -rw-r--r-- 1 root root 9471519 Jan 19 04:03 apache-tomcat-9.0.4.tar.gz [root@ecs-19cb ~]# cd apache-tomcat-9.0.4/ [root@ecs-19cb apache-tomcat-9.0.4]# ./bin/startup.sh Using CATALINA_BASE: /root/apache-tomcat-9.0.4 Using CATALINA_HOME: /root/apache-tomcat-9.0.4 Using CATALINA_TMPDIR: /root/apache-tomcat-9.0.4/temp Using JRE_HOME: /usr Using CLASSPATH: /root/apache-tomcat-9.0.4/bin/bootstrap.jar:/root/apache-tomcat-9.0.4/bin/tomcat-juli.jar Tomcat started.
3、關閉防火牆
[root@ecs-19cb etc]# systemctl stop firewalld [root@ecs-19cb etc]# 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)
4、查看tomcat默認端口8080是否開啟
[root@ecs-19cb ~]# netstat -ntlp Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:111 0.0.0.0:* LISTEN 1/systemd tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 1528/sshd tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN 1123/master tcp 0 0 127.0.0.1:32001 0.0.0.0:* LISTEN 1541/java tcp6 0 0 :::8009 :::* LISTEN 11809/java tcp6 0 0 :::111 :::* LISTEN 1/systemd tcp6 0 0 :::8080 :::* LISTEN 11809/java tcp6 0 0 :::22 :::* LISTEN 1528/sshd tcp6 0 0 ::1:25 :::* LISTEN 1123/master tcp6 0 0 127.0.0.1:8005 :::* LISTEN 11809/java
三、瀏覽器打開：http://ip:8080
Centos 7 firewall 命令：
查看已經開放的端口：
firewall-cmd --list-ports
開啟端口
firewall-cmd --zone=public --add-port=80/tcp --permanent
命令含義：
–zone #作用域
–add-port=80/tcp #添加端口，格式為：端口/通訊協議
–permanent #永久生效，沒有此參數重啟后失效
重啟防火牆
firewall-cmd --reload #重啟firewall
systemctl stop firewalld.service #停止firewall
systemctl disable firewalld.service #禁止firewall開機啟動
firewall-cmd --state #查看默認防火牆狀態（關閉后顯示notrunning，開啟后顯示running）
