在虛擬機CentOS 5.11 裏安裝 tomcat7

1.下載 apache-tomcat 7

wget http://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-7/v7.0.94/bin/apache-tomcat-7.0.94.tar.gz

2.解壓縮文件

tar -zxvf apache-tomcat-7.0.94.tar.gz

3.啓動tomcat

cd /usr/local/tomcat7/bin
./startup.sh

4. 在虛擬機本地鏈接tomcat首頁成功。

[root@localhost bin]# curl -I http://192.168.135.134:8080/
HTTP/1.1 200 OK
Server: Apache-Coyote/1.1
Content-Type: text/html;charset=ISO-8859-1
Transfer-Encoding: chunked
Date: Fri, 03 May 2019 01:39:17 GMT

5. 從宿主機訪問tomcat不成功

6. 防火牆開放8080端口，編輯文件 /etc/sysconfig/iptables

在-A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT這行的下方添加一行
-A INPUT -m state --state NEW -m tcp -p tcp --dport 8080 -j ACCEPT
修改後以下所示：

# Firewall configuration written by system-config-firewall
# Manual customization of this file is not recommended.
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
-A INPUT -p icmp -j ACCEPT
-A INPUT -i lo -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 8080 -j ACCEPT
-A INPUT -j REJECT --reject-with icmp-host-prohibited
-A FORWARD -j REJECT --reject-with icmp-host-prohibited
COMMIT

保存後重啓linux的防火牆服務，命令以下：

[root@localhost ~]# /etc/init.d/iptables restart

此時你會發如今宿主機的瀏覽器從新輸入網址就能夠看到咱們的Tomcat首頁了
