Question

我有一个我不明白的问题。查看我的配置，端口80是Listen on apache：

# grep -Rin Listen /etc/apache2/*
/etc/apache2/ports.conf:5:Listen 80

/etc/apache2/sites-enabled/global.conf

<VirtualHost *:80>
        ServerName global.grupoconstruserv.com.br
        DocumentRoot /var/www/global
        LogLevel debug
        ErrorLog /var/log/apache2/global-error.log
        CustomLog /var/log/apache2/global-access.log combined
</VirtualHost>
<Directory /var/www/global/>
    Options FollowSymLinks
    AllowOverride All
    Require all Granted
    <IfModule mod_rewrite.c>
        RewriteEngine On
        RewriteCond %{REQUEST_FILENAME} !-f
        RewriteCond %{REQUEST_FILENAME} !-d
        RewriteRule ^(.*) index.php/$1 [L]
  </IfModule>

 <IfModule !mod_rewrite.c>
      ErrorDocument 404 /404.php
  </IfModule>

</Directory>
# netstat -an|grep :80
tcp6       0      0 :::80                   :::*                    LISTEN     
tcp6       0      0 :::8080                 :::*                    LISTEN

防火墙没问题：

# iptables -L
Chain INPUT (policy ACCEPT)
target     prot opt source               destination         
ACCEPT     tcp  --  anywhere             anywhere             tcp dpt:http
LOG        tcp  --  anywhere             anywhere             tcp dpt:http LOG level warning

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination         

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination

tcpdump capture packts：

# tcpdump -nvvvi ens32 'port 80'
15:55:37.211374 IP (tos 0x0, ttl 55, id 6978, offset 0, flags [DF], proto TCP (6), length 60)

15:55:38.215987 IP (tos 0x0, ttl 64, id 0, offset 0, flags [DF], proto TCP (6), length 60)

    189.58.39.2.9656 > 192.168.1.12.80: Flags [S], cksum 0x45af (correct), seq 848450420, win 29200, options [mss 1452,sackOK,TS val 4134684630 ecr 0,nop,wscale 7], length 0

但是在httping上，浏览器（在其他设备上）返回超时：

httping http://global.grupoconstruserv.com.br:80/ -t2
PING global.grupoconstruserv.com.br:80 (/):
connect time out

Answer 1

我发现了问题。我有2条路线。数据包通过一条路由进入IN，另一条路径进入OUT，导致交通流失。所以我调整到OUT到与包IN相同的路径。

端口80上的tcpdump捕获，但apache没有响应
