网通与电信双线服务器实施的配置
转载:http://rico.zhyh.org/read.php?41 双线服务器的配置 大 | 中 | 小 [ 2006/11/20 15:57 | by Rico ] 公司开发网站,为解决南北访问的问题,我把服务器托管到一个双线机房。经过反复调试,终于完成相应的配置。现将配置过程简明记录如下,供大家参考。 一、服务器状态 网通使用第一块网卡(eth0): IP:218.57.200.242 掩码:255.255.255.0 网关:218.57.200.1 DNS1:202.102.152.3 DNS2:202.102.128.68 电信使用第二块网卡(eth1): IP:222.173.254.21 掩码:255.255.255.240 网关:222.173.254.17 DNS1:219.146.0.130 DNS2:219.150.32.132 二、配置网卡: # vi /etc/sysconfig/networking/profiles/default/ifcfg-eth0 DEVICE=eth0 ONBOOT=yes BOOTPROTO=none IPADDR=218.57.200.242 NETMASK=255.255.255.0 GATEWAY=218.57.200.1 TYPE=Ethernet USERCTL=no IPV6INIT=no PEERDNS=yes # vi /etc/sysconfig/networking/profiles/default/ifcfg-eth1 DEVICE=eth1 ONBOOT=yes BOOTPROTO=none IPADDR=222.173.254.21 NETMASK=255.255.255.240 GATEWAY=222.173.254.17 TYPE=Ethernet USERCTL=no IPV6INIT=no PEERDNS=yes # vi /etc/sysconfig/networking/profiles/default/route-eth1 GATEWAY0=218.57.200.1 NETMASK0=255.255.255.0 ADDRESS0=218.57.200.242 # vi /etc/sysconfig/networking/profiles/default/resolv.conf nameserver 202.102.152.3 nameserver 202.102.128.68 三、配置路由表 # vi /etc/iproute2/rt_tables,增加网通和电信两个路由表 252 cnc 251 tel 设置网通的路由表 # ip route add 218.57.200.0/24 via 218.57.200.242 dev eth0 table cnc # ip route add 127.0.0.0/8 dev lo table cnc # ip route add default via 218.57.200.1 dev eth0 table cnc 设置电信的路由表 ip route add 222.173.254.0/24 via 222.173.254.21 dev eth1 table tel ip route add 127.0.0.0/8 dev lo table tel ip route add default via 222.173.254.17 dev eth1 table tel 制定策略,让222.173.254.21的回应数据包走电信的路由表路由,218.57.200.242的回应数据包走网通的路由表路由 ip rule add from 222.173.254.21 table tel ip rule add from 218.57.200.242 table cnc 修改IP转发文件 # vi /etc/sysctl.conf net.ipv4.ip_forward = 1 net.ipv4.conf.default.rp_filter = 1 kernel.sysrq = 0 设置静态路由表文件 # vi /etc/sysconfig/static-routes eth0 net 218.57.200.242 netmask 255.255.255.0 gw 218.57.200.1 eth1 net 222.173.254.21 netmask 255.255.255.240 gw 222.173.254.17 将从两个WAN口出去的数据包进行IP伪装masquerade # /sbin/modprobe ip_conntrack_ftp # /sbin/modprobe ip_nat_ftp # /sbin/iptables -t nat -A postrouting -o eth0 -j masquerade # /sbin/iptables -t nat -A postrouting -o eth1 -j masquerade 设置默认网关为网通 # route add default gw 222.173.254.17 增加出口路由策略,客户端是网通的走网通线路,其余走电信线路。 ip rule add to 121.16.0.0/13 table cnc ip rule add to 121.24.0.0/14 table cnc ip rule add to 121.28.0.0/15 table cnc ip rule add to 121.30.0.0/16 table cnc ip rule add to 121.31.0.0/16 table cnc 其余省略... 刷新路由表 ip route flush cache 四、配置DNS 在服务器上配置自己的DNS解析,将域名服务器商处的域名解析指向服务器。 这样,来自网通的查询,将反馈网站网通的IP,其余反馈电信的IP。 配置named.conf view "cnc" { match-clients {121.16.0.0/13;121.24.0.0/14;121.28.0.0/15;121.30.0.0/16;121.31.0.0/16;121.47.0.0/16; 121.76.0.0/16;121.77.0.0/16;122.192.0.0/14;122.198.192.0/18;123.199.128.0/20; 124.108.40.0/21;124.128.0.0/13;124.160.0.0/16;124.161.0.0/16;124.162.0.0/16; 124.163.0.0/16;其余省略...;} recursion yes; zone "zhyh.org" { type master; file "/var/named/zhyh.org.cnc"; }; }; view "other" { match-clients { any; }; recursion no; zone "zhyh.org" { type master; file "/var/named/zhyh.org"; }; }; 配置zhyh.org.cnc,对应网通IP $TTL 86400 @ IN SOA zhyh.org. root ( 2006111800 ; Serial 28800 ; Refresh 14400 ; Retry 3600000 ; Expire 86400 ) ; Minimum IN NS zhyh.org. IN A 218.57.200.242 IN MX 10 mail www IN A 218.57.200.242 ns1 IN A 218.57.200.242 ns IN A 222.173.254.21 mail IN A 218.57.200.242 1 IN PTR localhost. 配置zhyh.org,对应电信IP $TTL 86400 @ IN SOA zhyh.org. root ( 2006111800 ; Serial 28800 ; Refresh 14400 ; Retry 3600000 ; Expire 86400 ) ; Minimum IN NS zhyh.org. IN A 222.173.254.21 IN MX 10 mail www IN A 222.173.254.21 ns IN A 222.173.254.21 ns1 IN A 218.57.200.242 mail IN A 222.173.254.21 1 IN PTR localhost. 配置222.173.254.zone、218.57.200.zone做反向解析; $TTL 86400 @ IN SOA zhyh.org. root.zhyh.org. ( 2006111813 3600 7200 3600000 86400 ) IN NS localhost. 242 IN PTR www.zhyh.org. 242 IN PTR ns1.zhyh.org. 242 IN PTR mail.zhyh.org. 五、配置apache,做好虚拟主机设置 # vi /etc/httpd/conf/httpd.conf NameVirtualHost 218.57.200.242:80 NameVirtualHost 222.173.254.21:80 <VirtualHost 222.173.254.21:80 218.57.200.242:80> ServerName zhyh.org DocumentRoot /var/www/html/ ServerAdmin webmaster@zhyh.org ErrorLog logs/zhyh.org-error_log CustomLog "|/usr/local/sbin/cronolog /var/log/httpd/zhyh.org-access_log.%Y%m%d" combined <IfModule mod_rewrite.c> RewriteEngine On RewriteRule ^(.*)/htm/(.*)$ $1.php?$2 </IfModule> </VirtualHost> <VirtualHost 222.173.254.21:80 218.57.200.242:80> ServerName www.zhyh.org DocumentRoot /var/www/html/zhyh.org ServerAdmin webmaster@zhyh.org ErrorLog logs/zhyh.org-error_log CustomLog "|/usr/local/sbin/cronolog /var/log/httpd/zhyh.org-access_log.%Y%m%d" combined </VirtualHost> |
