CloudStack 4.4+KVM之KVM计算节点安装

人气旺

二、KVM计算节点安装1. 修改主机名在hosts中增加

1 2 3 4

# vi /etc/hosts 192.168.10.190 node01.abc.com # vi /etc/sysconfig/network HOSTNAME=node01.abc.com

2. 关闭SELINUX设置

1 2	# vi /etc/selinux/config SELINUX=disabled

3. 关闭防火墙

1 2	# service iptables stop # chkconfig iptables off

4. 直接同步互联网时间服务器

1 2	# crontabc -e 01 */3 * * * /usr/sbin/ntpdate ntp.fudan.edu.cn

5. 配置系统YUM源1）配置163 CentOS系统安装源

1 2 3

# cd /etc/yum.repos.d/ # mv *.repo ../ # wget http://mirrors.163.com/.help/CentOS6-Base-163.repo

2）添加cloudstack软件包的官方源

1 2 3 4 5 6 7 8 9

# vi /etc/yum.repos.d/cloudstack.repo [cloudstack] name=cloudstack baseurl=http://cloudstack.apt-get.eu/rhel/4.4/ enabled=1 gpgcheck=0 # yum clean all # yum makecache # yum repolist

6. 安装cloudstack agent

1	# yum -y install cloudstack-agent

7. 安装KVM虚拟化环境1）要支持KVM

1 2 3

# egrep '(vmx|svm)' --color=always /proc/cpuinfo flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht syscall nx rdtscp lm constant_tsc arch_perfmon pebs bts xtopology tsc_reliable nonstop_tsc aperfmperf unfair_spinlock pni pclmulqdq vmx ssse3 cx16 sse4_1 sse4_2 popcnt xsave hypervisor lahf_lm arat epb xsaveopt pln pts dts tpr_shadow vnmi ept vpid flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht syscall nx rdtscp lm constant_tsc arch_perfmon pebs bts xtopology tsc_reliable nonstop_tsc aperfmperf unfair_spinlock pni pclmulqdq vmx ssse3 cx16 sse4_1 sse4_2 popcnt xsave hypervisor lahf_lm arat epb xsaveopt pln pts dts tpr_shadow vnmi ept vpid

2）安装KVM软件包

1	# yum -y install kvm python-virtinst libvirt tunctl bridge-utils virt-manager qemu-kvm-tools virt-viewer virt-v2v libguestfs-tools

3）配置QEMU

1 2 3

# vi /etc/libvirt/qemu.conf # 去掉其注释 vnc_listen=0.0.0.0

4) 配置Libvirt

1 2 3 4 5 6

# vi /etc/libvirt/libvirtd.conf listen_tls = 0 listen_tcp = 1 tcp_port = "16509" auth_tcp = "none" mdns_adv = 0

1 2 3 4 5

# vi /etc/sysconfig/libvirtd 取消如下行的注释： LIBVIRTD_ARGS="--listen" # service libvirtd restart # chkconfig libvirtd on

5) 配置agent

1 2 3

# vi /etc/cloudstack/agent/agent.properties # cloudstack管理服务器地址 host=192.168.10.185

6) 配置nfs域名

1 2	# vi /etc/idmapd.conf Domain = abc.com

8. 配置桥接网络1）创建桥接网卡配置文件

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

[iyunv@node01 ~]# cd /etc/sysconfig/network-scripts [iyunv@node01 ~]# cp ifcfg-eth0 ifcfg-cloudbr0 [iyunv@node01 ~]# cat ifcfg-eth0 DEVICE=eth0 TYPE=Ethernet ONBOOT=yes NM_CONTROLLED=yes BOOTPROTO=none HWADDR=00:0c:29:21:27:ea IPADDR=192.168.10.190 PREFIX=24 GATEWAY=192.168.10.254 DNS1=202.100.192.68 DEFROUTE=yes IPV4_FAILURE_FATAL=yes IPV6INIT=no NAME="System eth0" BRIDGE=cloudbr0

1 2 3 4 5 6 7 8 9 10 11 12 13

[iyunv@node01 ~]# cat /etc/sysconfig/network-scripts/ifcfg-cloudbr0 DEVICE=cloudbr0 TYPE=Bridge ONBOOT=yes NM_CONTROLLED=yes BOOTPROTO=static IPADDR=192.168.10.190 PREFIX=24 GATEWAY=192.168.10.254 DNS1=202.100.192.68 DEFROUTE=yes IPV4_FAILURE_FATAL=yes IPV6INIT=no

2）重启网络服务

1	# service network restart

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31

# ifconfig cloudbr0 Link encap:Ethernet HWaddr 00:0C:29:1D:8A:F0 inet addr:192.168.10.190 Bcast:192.168.10.255 Mask:255.255.255.0 inet6 addr: fe80::20c:29ff:fe1d:8af0/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:60 errors:0 dropped:0 overruns:0 frame:0 TX packets:22 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:4294 (4.1 KiB) TX bytes:2752 (2.6 KiB) eth0 Link encap:Ethernet HWaddr 00:0C:29:1D:8A:F0 inet6 addr: fe80::20c:29ff:fe1d:8af0/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:312744 errors:0 dropped:0 overruns:0 frame:0 TX packets:56830 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:447680883 (426.9 MiB) TX bytes:4767893 (4.5 MiB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:4 errors:0 dropped:0 overruns:0 frame:0 TX packets:4 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:240 (240.0 b) TX bytes:240 (240.0 b) virbr0 Link encap:Ethernet HWaddr 52:54:00:2D:AD:E4 inet addr:192.168.122.1 Bcast:192.168.122.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b)

9. 初始化cloudstack-agent

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19
