关闭IPv6 1、问题：使用yum下载东西的时候提示有一个IPv6的地址不可达，如下 http://download.fedoraproject.org/pub/epel/6/x86_64/repodata/924f970f6436162727781050e63524af37f891ba57c8a374cdd0a87e53d89180-filelists.sqlite.bz2: [Errno 14] PYCURL ERROR 7 - "Failed to connect to 2001:da8:8000:6023::230: Network is unreachable" Trying other mirror. Error: failure: repodata/924f970f6436162727781050e63524af37f891ba57c8a374cdd0a87e53d89180-filelists.sqlite.bz2 from epel: [Errno 256] No more mirrors to try. You could try using --skip-broken to work around the problem You could try running: rpm -Va --nofiles --nodigest 2、查看本机网卡配置，eth2上的确开了ipv6 inet6 [root@lvs05091 ~]# ifconfig -a eth2 Link encap:Ethernet HWaddr 00:50:56:A5:2F:9D inet addr:192.168.5.91 Bcast:192.168.5.255 Mask:255.255.255.0 inet6 addr: fe80::250:56ff:fea5:2f9d/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:522 errors:0 dropped:0 overruns:0 frame:0 TX packets:138 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:42263 (41.2 KiB) TX bytes:19212 (18.7 KiB) [root@lvs05091 modprobe.d]# netstat -an Active Internet connections (servers and established) Proto Recv-Q Send-Q Local Address Foreign Address State tcp 0 0 :::111 :::* LISTEN tcp 0 0 :::22 :::* LISTEN tcp 0 0 ::1:25 :::* LISTEN tcp 0 0 :::37256 :::* LISTEN ：：代表IPv6 3、关闭IPv6 修改sysctl.conf配置文件，加入如下内容 [root@lvs05091 etc]# vi sysctl.conf #shutdown IPv6 net.ipv6.conf.all.disable_ipv6 = 1 net.ipv6.conf.default.disable_ipv6 = 1 是修改配置生效 [root@lvs05091 etc]# sysctl -p 重启网卡：service network restart 备注:上面是永久关闭IPv6 也可以零时关闭，下次开机IPv6还会开启 echo 1 > /proc/sys/net/ipv6/conf/all/disable_ipv6 echo 1 > /proc/sys/net/ipv6/conf/default/disable_ipv6 4、再来查看接口配置，可以看到ipv6地址不在了 [root@lvs05091 etc]# ifconfig -a eth2 Link encap:Ethernet HWaddr 00:50:56:A5:2F:9D inet addr:192.168.5.91 Bcast:192.168.5.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:2336 errors:0 dropped:0 overruns:0 frame:0 TX packets:839 errors:0 dropped:0 overruns:0 carrier:0 这个时候使用yum下载东西就正常了。 (责任编辑：IT) |
