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，其他的不變。
①、以 root 身份登錄並設置主機名：
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，可以節省資源，當然大家可以使用Cloudstack的安裝腳本進行安裝，一樣的效果。
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 可以留空）。
[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：
對操作系統 iptables、sudoers 的設置（CloudStack 本身有安全性方面的要求，不是無限暴露給網絡，同時又需要一些管理權限來運行自身服務，因此要做這兩項的設置）。
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 需要兩類存儲（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，因此前述步驟中要啓動 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} #創建兩個目錄，分別作爲一級和二級存儲 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 #加入到所有INPUT之前，也可以關閉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 #測試能否掛載，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，我們可以先手動掛載nfs輔助存儲, 然後把290M KVM虛擬化模板先下載到輔助存儲目錄下，然後在導入, 導入系統虛擬機模板步是必須要配置的內容。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，最好是通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上操作。
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）、重新導入系統虛機：
詳見導入虛擬機模板部分。
5）、啓動cloudstack服務：
service cloudstack-management start |
這時，你再登陸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。
