CloudStack 4.4学习总结之cloudstack-agent安装

CloudStack 4.4学习总结之cloudstack-agent安装

 

2、节点安装（cloudstack-agent、KVM）：

 

    注：每个Hypervisor上，都要保证【/mnt】目录为空，否则，可能会出现InsufficientServerCapacityException （服务器资源不足）的报错。

 

cloud-agent-2.perofu.com和cloud-agent-1.perofu.com的安装步骤一样，即，所有cloudstack-agent节点的安装步骤均一样。

 

    下面以cloud-agent-1.perofu.com进行演示。

 

①、以 root 身份登录并设置主机名：

【cloud-agent-1.perofu.com】

hostname cloud-agent-1.perofu.com vi /etc/sysconfig/network     HOSTNAME=cloud-agent-1.perofu.com                                            vi /etc/hosts     127.0.0.1       cloud-agent-1.perofu.com     172.22.2.76          cloud-server.perofu.com     172.22.2.87     cloud-agent-1.perofu.com     172.22.2.100    cloud-agent-2.perofu.com

 

②、设置SELinux、关闭iptables并同步时间：

vi /etc/sysconfig/selinux     SELINUX=disabled setenforce 0 service iptables stop chkconfig iptables off yum install ntpdate -y echo '#ntpd' >>   /var/spool/cron/root echo "10 5 * * *   /usr/sbin/ntpdate ntp.api.bz &> /dev/null" >>   /var/spool/cron/root echo '' >>   /var/spool/cron/root service ntpd stop chkconfig ntpd off /usr/sbin/ntpdate   ntp.api.bz &> /dev/null

 

③、安装Management agent：

 

V4.4

vi   /etc/yum.repos.d/cloudstack.repo [cloudstack]   name=cloudstack   baseurl=http://cloudstack.apt-get.eu/rhel/4.4/                                   enabled=1   gpgcheck=0 yum -y install cloudstack-agent

 

 

V3.0

tar -axf   CloudStack-oss-3.0.2-1-rhel6.2.tar.gz -C /usr/local/src/ cd   /usr/local/src/CloudStack-oss-3.0.2-1-rhel6.2/ ./install.sh     A

 

    “A”------>    安装 CloudStack Agent 软件, CloudStack客户端。

 

 

④、安装KVM虚拟化环境：

 

1）、查看CPU是否支持虚拟化：

 

grep -E -o 'vmx|svm' /proc/cpuinfo

 

VMX：它是Intel处理器虚拟机技术标志；

SVM：它是AMD处理器虚拟机技术的标志。

 

注：linux发行版本必须在64bit环境中才能使用KVM。

 

[root@localhost ~]# grep -E -o 'vmx|svm'   /proc/cpuinfo                                            vmx

 

 

2）、安装kvm：

 

         yum源使用的是Centos 6.4的光盘镜像。

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

 

3）、修改vnc的监听端口：

 

         vnc默认的监听127.0.0.1。

         因为，在创建虚拟机时，需要连接vnc，去手动安装新系统。

 

cp /etc/libvirt/qemu.conf /etc/libvirt/qemu.conf.bak vi /etc/libvirt/qemu.conf          vnc_listen=0.0.0.0

 

4）、配置Libvirt：

vi /etc/libvirt/libvirtd.conf     listen_tls = 0                                                                   listen_tcp = 1     tcp_port = "16509"     auth_tcp = "none"     mdns_adv = 0 vi /etc/sysconfig/libvirtd     LIBVIRTD_ARGS="--listen" service libvirtd restart chkconfig libvirtd on

 

5）、检查KVM是否加载成功：

 

         如果没有输出信息，则表示没有加载成功。

lsmod | grep kvm

 

[root@localhost ~]# lsmod | grep kvm                                                                        kvm_intel              53484  0 kvm                   316506  1 kvm_intel

 

6）、检查KVM是否成功安装：

 

         -all关闭的也会显示。

 

virsh list --all

 

[root@localhost ~]# virsh list --all  Id      Name                             State ----------------------------------------------------

 

7）、配置网卡：

 

    虚拟机的网卡名称是：cloudbr0，不要自作聪明，用了br0，报了一个下午的错。

 

yum install -y tunctl cat << EOF > /etc/sysconfig/network-scripts/ifcfg-cloudbr0 DEVICE=cloudbr0 TYPE=Bridge BOOTPROTO=static IPV6INIT=no ONBOOT=yes IPADDR=172.22.2.87 NETMASK=255.255.0.0 GATEWAY=172.22.1.3 DNS1=8.8.8.8 DELAY=0 EOF   cp /etc/sysconfig/network-scripts/ifcfg-eth0   /etc/sysconfig/network-scripts/bak_ifcfg-eth0 cat << EOF > /etc/sysconfig/network-scripts/ifcfg-eth0 DEVICE=eth0 TYPE=Ethernet ONBOOT=yes NM_CONTROLLED=yes BOOTPROTO=none BRIDGE=cloudbr0 IPV6INIT=no EOF   /etc/init.d/network   restart   #查看桥接网络 brctl show

 

[root@localhost   CloudStack-oss-3.0.2-1-rhel6.2]# ifconfig cloudbr0   Link   encap:Ethernet  HWaddr   00:0C:29:40:7F:1D            inet addr:172.22.2.87  Bcast:172.22.255.255  Mask:255.255.0.0           inet6 addr:   fe80::20c:29ff:fe40:7f1d/64 Scope:Link           UP BROADCAST RUNNING MULTICAST  MTU:1500    Metric:1           RX packets:226 errors:0 dropped:0   overruns:0 frame:0           TX packets:28 errors:0 dropped:0   overruns:0 carrier:0           collisions:0 txqueuelen:0           RX bytes:18457 (18.0 KiB)  TX bytes:3116 (3.0 KiB)   eth0      Link encap:Ethernet  HWaddr 00:0C:29:40:7F:1D            inet6 addr:   fe80::20c:29ff:fe40:7f1d/64 Scope:Link           UP BROADCAST RUNNING MULTICAST  MTU:1500    Metric:1           RX packets:175448 errors:0   dropped:0 overruns:0 frame:0           TX packets:94709 errors:0 dropped:0   overruns:0 carrier:0           collisions:0 txqueuelen:1000           RX bytes:191337793 (182.4 MiB)  TX bytes:7210912 (6.8 MiB)

 

⑤、配置cloudstack-agent：

 

    这里也可以省略，只是在初始化的时候需要手动输入cloudstack-management的ip。

 

V4.4

vi /etc/cloudstack/agent/agent.properties #   cloudstack管理服务器地址                                                    host= 172.22.2.76

 

 

V3.0

vi /etc/cloud/agent/agent.properties #   cloudstack管理服务器地址                                                     host= 172.22.2.76

 

⑥、配置nfs域名：

 

vi /etc/idmapd.conf Domain   = perofu.com

 

⑦、初始化cloudstack-agent：

    一路回车，即可。

 

V4.4

cloudstack-setup-agent

 

 

V3.0

cloud-setup-agent

 

[root@cloud-agent-1   ~]# cloud-setup-agent Welcome   to Cloud Agent Setup: Please   input the Management Server Name/IP:[172.22.2.76] Please   input the Zone Id:[default] Please   input the Pod Id:[default] Please   input the Cluster Id:[] Please   choose which network used to create VM:[br0] Starting   to configure your system: Configure   SElinux ...         [OK] Configure   Network ...         [OK] Configure   Libvirt ...         [OK] Configure   Firewall ...        [OK] Configure   cloudAgent ...      [OK] Cloud   Agent setup is Done!

 

 

Libvirt报错：

[root@cloud-agent-1   ~]# cloud-setup-agent Welcome   to Cloud Agent Setup: Please   input the Management Server Name/IP:[172.22.2.76] Please   input the Zone Id:[default] Please   input the Pod Id:[default] Please   input the Cluster Id:[] Please   choose which network used to create VM:[br0] Starting   to configure your system: Configure   SElinux ...         [OK] Configure   Network ...         [OK] Configure Libvirt ...         [Failed] Traceback   (most recent call last):   File   "/usr/bin/cloud-setup-agent", line 112, in <module>     syscfg.config()   File "/usr/lib/python2.6/site-packages/cloudutils/syscfg.py",   line 76, in config     raise CloudInternalException() TypeError:   __init__() takes exactly 2 arguments (1 given)

 

解决：

 

    Libvirt启动失败，端口没看到。

 

[root@localhost   CloudStack-oss-3.0.2-1-rhel6.2]# /etc/init.d/libvirtd restart Stopping   libvirtd daemon:                                  [FAILED] Starting   libvirtd daemon: libcgroup   initialization failed: Cgroup is not mounted                                                              [FAILED] yum list libcgroup -y vi /etc/cgconfig.conf     group virt {         cpu {                 cpu.shares = 9216;         } } /etc/init.d/cgconfig   restart /etc/init.d/libvirtd   restart chkconfig cgconfig on

 

⑧、启动cloud-agent：

 

    这里，不需要手动启动cloud-agent，当在manager上创建主机时，manager会自动启动cloud-agent的。

 

/etc/init.d/cloud-agent   start

 

    启动失败啊.

⑨、卸载并清空/mnt目录：

 

    一定要保证/mnt目录没有被使用，且目录为空，否则CloudStack无法对其挂载Primary Storage，新建实例，可能会失败，除非你有多个agent，/mnt已有的数据，请提前保存好。

 

umount /mnt                                                    rm -rf /mnt/*

 

⑩、等待加入cloudstack：

 

    到此cloudstack-agent就配置完成了，现在的cloudstack-agent可以在创建区域时加入，也可以在创建完区域后，手动加入，后面均有介绍。
