CentOS6.5以前，内核不支持网络namespace，需要升级内核和iproute。CentOS6.5以后内核已支持网络namespace，只需要升级iproute即可。

我的系统版本是6.7的。介绍2个方法，亲测可用。

[root@centos67 ~]# cat /etc/redhat-release CentOS release 6.7 (Final)[root@centos67 ~]# uname -r2.6.32-573.el6.x86_64

方法一：升级iproute

yum install -y http://rdo.fedorapeople.org/rdo-release.rpm

修改地址

cat /etc/yum.repos.d/rdo-release.repo[openstack-kilo]name=OpenStack Kilo Repositorybaseurl=https://repos.fedorapeople.org/repos/openstack/EOL/openstack-icehouse/epel-6/skip_if_unavailable=0enabled=1gpgcheck=0gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-RDO-kilo

安装iproute

yum install -y iproute

方法二：升级内核\

通过yum快速升级CentOS 6.x 内核到3.1.0

# rpm -ivh http://www.elrepo.org/elrepo-release-6-5.el6.elrepo.noarch.rpm# yum --enablerepo=elrepo-kernel install kernel-lt -y

在grub.conf中确定装好的内核在哪个位置：

# vi /etc/grub.confdefault=0

重启系统，查看内核信息

[root@centos67 ~]# uname -r3.10.94-1.el6.elrepo.x86_64

更新iproute软件包

yum install -y http://rdo.fedorapeople.org/rdo-release.rpm

修改地址

cat /etc/yum.repos.d/rdo-release.repo[openstack-kilo]name=OpenStack Kilo Repositorybaseurl=https://repos.fedorapeople.org/repos/openstack/EOL/openstack-icehouse/epel-6/skip_if_unavailable=0enabled=1gpgcheck=0gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-RDO-kilo

升级iprpute 软件包

# yum upgrade iproute

[root@centos67 ~]# rpm -qa|grep iprouteiproute-2.6.32-130.el6ost.netns.2.x86_64

完毕！
