CloudStack 4.4學習總結之cloudstack-management安裝

CloudStack 4.4學習總結之cloudstack-management安裝

 

1、cloudstack-management安裝步驟（CloudStack 3.0和4.4軟件包）

 

    CloudStack的3.0版本和4.4版本的命令和目錄有很大的區別。

 

    下面的命令，標註部分爲3.0和4.4的區別，其餘的不變。

 

①、以 root 身份登陸並設置主機名：

主機名：    【cloud-server.perofu.com】

    ip：        【172.22.2.76】

 

hostname cloud-server.perofu.com vi /etc/sysconfig/network     HOSTNAME=cloud-server.perofu.com                                             vi /etc/hosts     127.0.0.1       cloud-server.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、設置SELinux並同步時間：

vi /etc/sysconfig/selinux     SELINUX=disabled                                                             setenforce 0 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、安裝MySQL：

 

    這裏將mysql單獨拿出來安裝，用的是光盤的yum源，能夠節省資源，固然你們可使用Cloudstack的安裝腳本進行安裝，同樣的效果。

 

yum install openssl-devel   mysql-server mysql-devel -y cp -a   /usr/share/doc/mysql-server-5.1.66/my-medium.cnf /etc/my.cnf vi /etc/my.cnf     [mysqld]     innodb_rollback_on_timeout=1     innodb_lock_wait_timeout=600       max_connections=350       log-bin=mysql-bin       binlog-format=ROW /etc/init.d/mysqld start chkconfig mysqld on /usr/bin/mysql_secure_installation  #配置mysql安全，可直接全選Y

 

④、安裝cloudstack-management：

 

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-management httpd

 

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     M

 

「M」------>    安裝 Management Server 軟件。

「D」------>    安裝 MySQL。

     

 

⑤、初始化CloudStack的數據庫：

 

V4.4

cloudstack-setup-databases cloud:dbpassword@localhost  --deploy-as=root:password

 

[root@cloud-server   ~]# cloudstack-setup-databases cloud:123456@localhost  --deploy-as=root:123456

 

 

V3.0

cloud-setup-databases   cloud:dbpassword@localhost    --deploy-as=root:password

 

    注：即表示以 root 用戶身份來生成數據庫，該數據庫屬於新建的 cloud 用戶（密碼 dbpassword 能夠留空）。

 

[root@cloud-server   ~]# cloud-setup-databases cloud:123456@localhost --deploy-as=root:123456 Mysql   user name:cloud                                                             [ OK ] Mysql   user password:123456                                                        [ OK ] Mysql   server ip:localhost                                                         [ OK ] Mysql   server port:3306                                                            [ OK ] Mysql   root user name:root                                                         [ OK ] Mysql   root user password:123456                                                   [ OK ] Checking   Cloud database files ...                                                 [ OK ] Checking   local machine hostname ...                                               [ OK ] Checking   SELinux setup ...                                                        WARNING: We detected that your SELinux is not configured in   permissive. to make sure cloudstack won't block by SELinux after system   reboot, we strongly suggest you setting it in permissive in   /etc/selinux/config, then reboot the machine. [   OK ] Detected   local IP address as 172.22.2.76, will use as cluster management server node   IP[ OK ] Preparing   /etc/cloud/management/db.properties                                   [ OK ] Applying   /usr/share/cloud/setup/create-database.sql                             [ OK ] Applying   /usr/share/cloud/setup/create-schema.sql                               [ OK ] Applying   /usr/share/cloud/setup/create-database-premium.sql                     [ OK ] Applying   /usr/share/cloud/setup/create-schema-premium.sql                       [ OK ] Applying   /usr/share/cloud/setup/server-setup.sql                                [ OK ] Applying   /usr/share/cloud/setup/templates.sql                                   [ OK ] Applying   /usr/share/cloud/setup/create-index-fk.sql                             [ OK ] Processing   encryption ...                                                         [ OK ] Finalizing   setup ...                                                              [ OK ]   CloudStack   has successfully initialized database, you can check your database   configuration in /etc/cloud/management/db.properties

 

    /etc/cloud/management/db.properties存放CloudStack數據庫的相關信息。

 

⑥、初始化cloudstack-management並啓動：

 

    對操做系統 iptables、sudoers 的設置（CloudStack 自己有安全性方面的要求，不是無限暴露給網絡，同時又須要一些管理權限來運行自身服務，所以要作這兩項的設置）。

 

V4.4

 

/etc/init.d/httpd start chkconfig httpd on‍                                                               cloudstack-setup-management /etc/init.d/cloudstack-management   start chkconfig cloudstack-management   on

 

V3.0

cloud-setup-management                                                            /etc/init.d/cloud-management   start chkconfig cloud-management   on

 

 

[root@cloud-server   ~]# cloud-setup-management Starting   to configure CloudStack Management Server: Configure   sudoers ...         [OK] Configure   Firewall ...        [OK] Configure   CloudStack Management Server ...[OK] CloudStack   Management Server setup is Done!

 

manager的日誌文件：/var/log/cloud/management/management-server.log

 

⑦、配置NFS：

 

前面講過，CloudStack 須要兩類存儲（primary storage 和 secondary storage）來支持它的 cluster 和 host，本節中由 NFS 來提供這兩個存儲，所以前述步驟中要啓動 NFS 服務。同時爲了方便起見，NFS Server 也由 cloud-server.perofu.com 充當。

 

yum install nfs-utils -y mkdir -p   /data/{primary,secondary}  #建立兩個目錄，分別做爲一級和二級存儲 chmod 777 /data/* vi /etc/exports     /data/primary   *(rw,fsid=1,async,no_root_squash,no_subtree_check)     /data/secondary *(rw,fsid=2,async,no_root_squash,no_subtree_check) exportfs -a     #導出/data 目錄 cp /etc/sysconfig/nfs   /etc/sysconfig/nfs.bak > /etc/sysconfig/nfs vi /etc/sysconfig/nfs       #用於iptables    LOCKD_TCPPORT=32803     LOCKD_UDPPORT=32769     MOUNTD_PORT=892     RQUOTAD_PORT=875     STATD_PORT=662     STATD_OUTGOING_PORT=2020 vi /etc/sysconfig/iptables  #加入到全部INPUT以前，也能夠關閉iptables     -A INPUT -m state --state NEW -p udp   --dport 111 -j ACCEPT     -A INPUT -m state --state NEW -p tcp   --dport 111 -j ACCEPT      -A INPUT -m state --state NEW -p tcp   --dport 2049 -j ACCEPT      -A INPUT -m state --state NEW -p tcp   --dport 32803 -j ACCEPT       -A INPUT -m state --state NEW -p udp   --dport 32769 -j ACCEPT      -A INPUT -m state --state NEW -p tcp   --dport 892 -j ACCEPT      -A INPUT -m state --state NEW -p udp   --dport 892 -j ACCEPT      -A INPUT -m state --state NEW -p tcp   --dport 875 -j ACCEPT      -A INPUT -m state --state NEW -p udp   --dport 875 -j ACCEPT      -A INPUT -m state --state NEW -p tcp   --dport 662 -j ACCEPT      -A INPUT -m state --state NEW -p udp   --dport 662 -j ACCEPT service iptables restart service iptables save vi /etc/idmapd.conf     #管理服務器（cloud-server.perofu.com）和 hypervisor都要     Domain = perofu.com service rpcbind restart service nfs restart mkdir /tmp/primarymount mount -t nfs 172.22.2.76:/data/primary   /tmp/primarymount #測試可否掛載，iptables umount /tmp/primarymount/ service rpcbind restart service nfs restart chkconfig nfs on chkconfig rpcbind on

 

[root@cloud-server   ~]# df -h Filesystem            Size  Used Avail Use% Mounted on /dev/mapper/VolGroup-lv_root                        19G  1.7G     16G  10% / tmpfs                 116M     0    116M   0% /dev/shm /dev/sda1             485M   32M    428M   7% /boot /dev/sr0              4.1G  4.1G       0 100% /mnt 172.22.2.76:/data/primary 19G  1.7G     16G  10% /tmp/primarymount

 

 

⑧、導入虛擬機模板：

系統虛擬機模板按要求要存放在輔助存儲上的，咱們能夠先手動掛載nfs輔助存儲, 而後把290M KVM虛擬化模板先下載到輔助存儲目錄下，而後在導入, 導入系統虛擬機模板步是必需要配置的內容。本例採用KVM虛擬化，下載導入KVM虛擬機模板。

 

         1）、在management上掛載輔助存儲；

         2）、下載kvm模板，並上傳到輔助存儲；

         3）、導入。

 

         systemvm64template-4.4.0-6-kvm.qcow2.bz2模板文件有點大，最好是經過別的下載工具進行下載，如百度網盤的離線下載，再上傳使用。

 

         在management上操做。

V4.4

/usr/share/cloudstack-common/scripts/storage/secondary/cloud-install-sys-tmplt   -m /tmp/secondarymount -f systemvm64template-4.4.0-6-kvm.qcow2.bz2 -h kvm -F

 

V3.0

mkdir /tmp/secondarymount mount -t nfs 172.22.2.76:/data/secondary   /tmp/secondarymount cd /tmp/secondarymount wget http://cloudstack.apt-get.eu/systemvm/4.4/systemvm64template-4.4.0-6-kvm.qcow2.bz2 /usr/lib64/cloud/agent/scripts/storage/secondary/cloud-install-sys-tmplt   -m /tmp/secondarymount -f systemvm64template-4.4.0-6-kvm.qcow2.bz2 -h kvm -F

 

    系統虛擬機默認用戶名密碼：root/6m1ll10n

 

[root@cloud-server   ~]# mkdir /tmp/secondarymount [root@cloud-server   ~]# mount -t nfs 172.22.2.76:/data/secondary /tmp/secondarymount [root@cloud-server   ~]# cd /tmp/secondarymount [root@cloud-server   secondarymount]# rz rz   waiting to receive.

⑨、訪問web：

 

http://172.22.2.76:8080/client/

默認用戶名和密碼爲admin, password

 

V4.4

 

V3.0

 

 

 

⑩、CloudStack如何重裝：

1）、停掉CloudStack服務：

 

service   cloudstack-management stop

 

 

2）、刪除數據庫：

 

mysql>drop   database cloud;                                                      mysql>drop   database cloud_usage; mysql>drop   database cloudbridge; mysql>\q

3）、初始化CloudStack數據庫：

    詳見初始化CloudStack數據庫部分。

 

4）、從新導入系統虛機：

    詳見導入虛擬機模板部分。

 

5）、啓動cloudstack服務：

 

service   cloudstack-management start

這時，你再登錄就會發現一個全新的CloudStack啦。

    到此，CloudStack Management就安裝完成了，下節進入CloudStack Agent與KVM的安裝。
