本文介绍CentOS 6.3操作系统主机安装 CloudStack 4.1.1 AllInOne的运行环境。 前置条件 Management Server, Database, and Storage System Requirements Operating system: Preferred: CentOS/RHEL 6.3+ or Ubuntu12.04(.1) 64-bit x86 CPU (more cores results in better performance) 4 GB of memory 250 GB of local disk (more results in better capability; 500 GBrecommended) At least 1 NIC Statically allocated IP address Fully qualified domain name as returned by the hostnamecommand Host/Hypervisor System Requirements Must support HVM (Intel-VT or AMD-V enabled). 64-bit x86 CPU (more cores results in better performance) Hardware virtualization support required 4 GB of memory 36 GB of local disk At least 1 NIC  When you deploy CloudStack, the hypervisor hostmust not have any VMs already running All hosts within a cluster must be homogeneous. The CPUs must be ofthe same type, count, and feature flags. KVM 主机需求http://cloudstack.apache.org/docs/en-US/Apache_CloudStack/4.1.1/html/Installation_Guide/hypervisor-kvm-install-flow.html#hypervisor-kvm-requirements XenServer 主机需求http://cloudstack.apache.org/docs/en-US/Apache_CloudStack/4.1.1/html/Installation_Guide/citrix-xenserver-installation.html#system-requirements-xenserver-hosts vSphere 主机需求http://cloudstack.apache.org/docs/en-US/Apache_CloudStack/4.1.1/html/Installation_Guide/vmware-install.html#vmware-requirements 禁用IPv6 # service ip6tables stop # chkconfig ip6tables off (一)安装配置管理服务器 设置静态网络IP地址 #vim /etc/sysconfig/network-scripts/ifcfg-eth0 除物理MAC,静态IP地址、网关、掩码以外,参考如下设置 DEVICE=eth0 HWADDR=00:1F:16:34:xx:yy ONBOOT=yes HOTPLUG=no BOOTPROTO=static IPV6INIT=no NM_CONTROLLED=no #这里不需要NetworkManager托管网络配置,将NetworkManager断开Wired Networks和Wireless Networks TYPE=Ethernet IPADDR=192.168.0.103 NETMASK=255.255.255.0 DNS1=202.96.134.33 DNS2=202.96.128.86 DOMAIN=cloudstack.org Host名称 # vim /etc/sysconfig/network NETWORKING=yes HOSTNAME=mgmt1.cloudstack.org NETWORKING_IPV6=no NOZEROCONF=yes GATEWAY=192.168.0.1 # vim /etc/hosts 127.0.0.1   localhost 192.168.0.103 mgmt1.cloudstack.org DNS(广东电信) # vim /etc/resolv.conf nameserver 127.0.0.1 # Generated by NetworkManager search cloudstack.org nameserver 202.96.134.33 nameserver 202.96.128.86 重启网络 # service networkrestart 开机启用网络 # chkconfig networkon 开机启用NetworkManager # chkconfig --add NetworkManager # chkconfig NetworkManager on 验证网络 # ping 192.168.0.1 # ping www.baidu.com # hostname --fqdn 安装并启动NTP服务器 #yum install ntp # service ntpd start 将其加入boot时启动 # chkconfig ntpd on 安装CloudStack管理节点 #yum install cloudstack-management 安装MySQL数据库 #yum install mysql-server 修改/etc/my.cnf,在 [mysqld] 段 datadir 下增加以下内容: 注意:若单个management节点max_connections配置为350 innodb_rollback_on_timeout=1 innodb_lock_wait_timeout=600 max_connections=350 log-bin=mysql-bin binlog-format = 'ROW' 重启MySQL #service mysqld restart 建立安全链接,除了"Disallow root login remotely?"选项以外,全部选择“y” #mysql_secure_installation 放宽SELinux权限 1)检查是否安装了selinux,如果没有,那么跳过后续步骤 #rpm -qa | grep selinux 2)修改/etc/selinux/config,将SELINUX=enforcing修改为SELINUX=permissive 3)及时生效 #setenforce permissive 建立CloudStack的MySQL数据库帐户cloud及口令密码,以及初始化元数据: #cloudstack-setup-databasescloud:<dbpassword>@localhost \ --deploy-as=root:<password>\ -e <encryption_type> \ -m <management_server_key>\ -k <database_key> \ -i <management_server_ip> 以上命令根据实际情况替换,encryption_type默认值为file,management_server_key默认值为password,database_key默认值为password,详细参考http://cloudstack.apache.org/docs/en-US/Apache_CloudStack/4.1.1/html/Installation_Guide/management-server-install-flow.html#about-password-encryption,如下参考: #cloudstack-setup-databases cloud:[email protected] \ --deploy-as=root:root \ -m cloud \ -k cloud \ -i mgmt1.cloudstack.org 若KVM hypervisor在同一台主机运行,那么修改/etc/sudoers增加以下内容: Defaults:cloud !requiretty 初始化CloudStack管理服务器 #cloudstack-setup-management 注意:只有XenServer需要下载vhd-util (二)在其他节点独立安装数据库 若不是采取CloudStack的AllInOne方式,则需要在新主机上安装MySQL 修改/etc/my.cnf,在 [mysqld] 段 datadir 下增加以下内容: innodb_rollback_on_timeout=1 innodb_lock_wait_timeout=600 max_connections=350 log-bin=mysql-bin binlog-format = 'ROW' bind-address = 0.0.0.0 重启MySQL #service mysqld restart 将MySQL加入boot时启动 # chkconfig mysqld on 建立安全链接,除了"Disallow root login remotely?"选项以外,全部选择“y” #mysql_secure_installation 修改防火墙,允许MySQL的3306端口运行 #vim /etc/sysconfig/iptables 在:INPUT ACCEPT [0:0]下面增加以下内容: -A INPUT -p tcp --dport 3306 -j ACCEPT 重启iptables #service iptables restart 重新建立CloudStack的MySQL数据库帐户,以及初始化元数据,参考如上所述: #cloudstack-setup-databasescloud:<dbpassword>@localhost \ --deploy-as=root:<password>\ -e <encryption_type> \ -m <management_server_key>\ -k <database_key> \ -i <management_server_ip> (三)使用Management Server作为 NFS Server 生产环境建议独立安装网络文件系统,详细参考http://cloudstack.apache.org/docs/en-US/Apache_CloudStack/4.1.1/html/Installation_Guide/management-server-install-flow.html#nfs-shares-on-separate-server 本文CloudStack的AllInOne方式,网络文件系统安装在同一主机 #yum install nfs-utils #mkdir -p /export/primary #mkdir -p /export/secondary #vi /etc/exports 填写以下内容: /export *(rw,async,insecure,no_root_squash) NFS Server导出export目录 #exportfs -arv #vi /etc/sysconfig/nfs 取消以下行的注释 LOCKD_TCPPORT=32803 LOCKD_UDPPORT=32769 MOUNTD_PORT=892 RQUOTAD_PORT=875 STATD_PORT=662 STATD_OUTGOING_PORT=2020 修改iptables #vi /etc/sysconfig/iptables 在:INPUT ACCEPT[0:0]之前加入以下行:(这里<NETWORK>替换当前主机IP或域名) -A INPUT -s <NETWORK> -m state--state NEW -p udp --dport 111 -j ACCEPT -A INPUT -s <NETWORK> -m state--state NEW -p tcp --dport 111 -j ACCEPT -A INPUT -s <NETWORK> -m state--state NEW -p tcp --dport 2049 -j ACCEPT -A INPUT -s <NETWORK> -m state--state NEW -p tcp --dport 32803 -j ACCEPT -A INPUT -s <NETWORK> -m state--state NEW -p udp --dport 32769 -j ACCEPT -A INPUT -s <NETWORK> -m state--state NEW -p tcp --dport 892 -j ACCEPT -A INPUT -s <NETWORK> -m state--state NEW -p udp --dport 892 -j ACCEPT -A INPUT -s <NETWORK> -m state--state NEW -p tcp --dport 875 -j ACCEPT -A INPUT -s <NETWORK> -m state--state NEW -p udp --dport 875 -j ACCEPT -A INPUT -s <NETWORK> -m state--state NEW -p tcp --dport 662 -j ACCEPT -A INPUT -s <NETWORK> -m state--state NEW -p udp --dport 662 -j ACCEPT # cat /etc/sysconfig/iptables 如果IP不对,可通过命令进行修改:sed -i's/127.0.0.1/mgmt1.cloudstack.org/g'  /etc/sysconfig/iptables 重启iptables #service iptables restart #service iptables save 修改hypervisor主机 和 Management服务器idmapd #vi /etc/idmapd.conf 取消Domain注释,并写入域名 Domain = cloudstack.org 重启Management服务器 登录hypervisor主机,验证上述配置,并将其加入boot时启动 # service rpcbind start # service nfs start # chkconfig nfs on # chkconfig rpcbind on # reboot    登录hypervisor主机,在Management服务器上测试挂载/export目录 # mkdir /primarymount # mount -t nfs mgmt1.cloudstack.org:/export/primary/primarymount # umount /primarymount # mkdir /secondarymount # mount -t nfs mgmt1.cloudstack.org:/export/secondary/secondarymount # umount /secondarymount 检查是否挂载发生错误 # tail -f /var/log/messages 验证NFS挂载情况 # reboot # showmount -e mgmt1.cloudstack.org Export list for mgmt1.cloudstack.org: /export * # mount | grep primary # mount -l ... ... mgmt1.cloudstack.org:/export/primary on /mnt/b050decd-2d7f-3428-9dcf-81bd4b2fdeda type nfs (rw,noac,vers=4,addr=192.168.0.103,clientaddr=192.168.0.103) (当Zone配置完毕,Secondary storage vm s-1-VM 和Console proxy v-2-VM才会挂载到NFS存储) (四)安装额外的其他管理节点服务器(可选) 开机启动服务 # service rpcbind start # service nfs start # chkconfig nfs on # chkconfig rpcbind on 重新建立CloudStack的MySQL数据库帐户,以及初始化元数据,参考如上所述: #cloudstack-setup-databasescloud:<dbpassword>@localhost \ --deploy-as=root:<password>\ -e <encryption_type> \ -m <management_server_key>\ -k <database_key> \ -i <management_server_ip> 初始化配置 # cloudstack-setup-management 若有多台额外的管理服务器,重复执行上述步骤 管理节点服务器间集群负载均衡配置参考以下链接: http://cloudstack.apache.org/docs/en-US/Apache_CloudStack/4.1.1/html/Installation_Guide/management-server-install-flow.html (五)准备System VM Template 注意:若前述步骤CloudStack database 加密方式encryption type 选择的是 "web",那么必须使用-s 参数:     For XenServer:     #/usr/share/cloudstack-common/scripts/storage/secondary/cloud-install-sys-tmplt-m /mnt/secondary -uhttp://download.cloud.com/templates/acton/acton-systemvm-02062012.vhd.bz2-h xenserver -s -F     ForvSphere:     #/usr/share/cloudstack-common/scripts/storage/secondary/cloud-install-sys-tmplt-m /mnt/secondary -uhttp://download.cloud.com/templates/burbank/burbank-systemvm-08012012.ova-h vmware -s   -F     ForKVM:     #/usr/share/cloudstack-common/scripts/storage/secondary/cloud-install-sys-tmplt-m /mnt/secondary -uhttp://download.cloud.com/templates/acton/acton-systemvm-02062012.qcow2.bz2-h kvm -s -F 本机KVM执行命令参考如下: #/usr/share/cloudstack-common/scripts/storage/secondary/cloud-install-sys-tmplt-m /secondarymount -uhttp://download.cloud.com/templates/acton/acton-systemvm-02062012.qcow2.bz2-h kvm -F -o mgmt1.cloudstack.org -r cloud -d cloud 当然也可以下载到本机进行安装,命令由-u改为-f参数指定文件路径 (六)登录CloudStack 检测CloudStack运行状态 #service cloudstack-management status 或者观察启动日志 #tail -100f /var/log/cloudstack/management/catalina.out 成功启动后登录 http://mgmt1.cloudstack.org:8080/client 默认用户名及密码admin/password (七)卸载CloudStack及MySQL数据库 #yum remove cloudstack-management #yum remove mysql-server
