1）清理ovirt相关服务（包括HA,engine）： 停用并卸载ovirt,vdsm,libvirt相关的服务。 yum remove *ovirt* *vdsm* *libvirt* *rhev* *glusterfs* *postgresql* rm /etc/ovirt* /etc/vdsm /etc/libvirt* /etc/pki/vdsm /etc/pki/libvirt /etc/pki/CA/cacert.pem* /var/run/vdsm /var/run/libvirt /var/lib/vdsm /var/lib/libvirt /var/lib/ovirt* /var/lib/pgsql /var/log/*ovirt* /var/log/vdsm /var/log/libvirt 如果需要清理vdsm管理的multipath： 首先，查看列表： multipath -l 清空： multipath -F 移除包： yum remove *multipath* 2）清理网卡和防火墙的配置 【网卡】以em1桥接ovirtmgmt，em2+em3=bond1桥接br1为例 # cd /etc/sysconfig/network-scripts/ # brctl delbr \;vdsmdummy\; # ifdown br1 \ && ifdown bond1 \ && echo -bond1 >/sys/class/net/bonding_masters \ && mv ifcfg-bond1 ifcfg-br1 /tmp/ \ && cat <<'_EOF' >ifcfg-em2 && ifup em2 DEVICE=em2 TYPE=Ethernet ONBOOT=yes NM_CONTROLLED=yes BOOTPROTO=none IPADDR=10.60.200.86 NETMASK=255.255.255.0 _EOF # cat <<'_EOF' >ifcfg-em3 DEVICE=em3 TYPE=Ethernet ONBOOT=no NM_CONTROLLED=yes BOOTPROTO=dhcp _EOF # brctl delif ovirtmgmt em1 && ifdown ovirtmgmt && brctl delbr ovirtmgmt \ && cat <<'_EOF' >ifcfg-em1 && ifup em1 && mv *ovirt* /tmp/ DEVICE=em1 TYPE=Ethernet ONBOOT=yes NM_CONTROLLED=yes BOOTPROTO=none IPADDR=10.50.200.86 NETMASK=255.255.255.0 GATEWAY=10.50.200.1 _EOF 【防火墙】 # cat <<'_EOF' > /etc/sysconfig/iptables && service iptables reload *filter :INPUT ACCEPT [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT -A INPUT -p icmp -j ACCEPT -A INPUT -i lo -j ACCEPT -A INPUT -p tcp -m state --state NEW -m tcp --dport 22 -j ACCEPT -A INPUT -j REJECT --reject-with icmp-host-prohibited -A FORWARD -j REJECT --reject-with icmp-host-prohibited COMMIT _EOF (责任编辑：IT) |
