CloudStack 4.4+KVM之管理服务器安装

人气旺

一、cloudstack管理服务器网络准备1. 主机规划nfs            192.168.10.180  (secondary)   
cloudstack     192.168.10.185  (primary)   
node01         192.168.10.190   
node02         192.168.10.191

2. 修改主机名在hosts中增加   

1 2 3 4

# vi /etc/hosts 192.168.10.185 cloudstack cloudstack.abc.com # vi /etc/sysconfig/network HOSTNAME=cloudstack.abc.com

3. 关闭SELINUX设置

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

需要重启生效，直接生效配置。

1 2 3

# setenforce 0 # getenforce disabled

4. 关闭防火墙

1 2	service iptables stop chkconfig iptables off

5. 配置NTP时间服务同步互联网时间服务器

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

6. 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(可选方式)

1 2 3 4 5 6

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

7. 安装Management Server

1	# yum -y install cloudstack-management

8. 安装mysql并配置数据库1）安装mysql-server

1	# yum -y install mysql-server

2）修改mysql配置并加入以下几行

1 2 3 4 5 6 7

# vi /etc/my.cnf datadir=/var/lib/mysql innodb_rollback_on_timeout=1 innodb_lock_wait_timeout=600 max_connections=350 log-bin=mysql-bin binlog-format = 'ROW'

3）重启mysql，并加入开机自启动

1 2	# service mysqld start # chkconfig mysqld on

4）执行mysql的安全配置，设置密码等过程，如需要简单可直接全选Y.

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 32 33 34 35 36 37 38 39 40 41 42 43 44 45

# mysql_secure_installation NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY! In order to log into MySQL to secure it, we'll need the current password for the root user. If you've just installed MySQL, and you haven't set the root password yet, the password will be blank, so you should just press enter here. Enter current password for root (enter for none): OK, successfully used password, moving on... Setting the root password ensures that nobody can log into the MySQL root user without the proper authorisation. Set root password? [Y/n] y New password: Re-enter new password: Password updated successfully! Reloading privilege tables.. ... Success! By default, a MySQL installation has an anonymous user, allowing anyone to log into MySQL without having to have a user account created for them. This is intended only for testing, and to make the installation go a bit smoother. You should remove them before moving into a production environment. Remove anonymous users? [Y/n] y ... Success! Normally, root should only be allowed to connect from 'localhost'. This ensures that someone cannot guess at the root password from the network. Disallow root login remotely? [Y/n] n ... skipping. By default, MySQL comes with a database named 'test' that anyone can access. This is also intended only for testing, and should be removed before moving into a production environment. Remove test database and access to it? [Y/n] y - Dropping test database... ... Success! - Removing privileges on test database... ... Success! Reloading the privilege tables will ensure that all changes made so far will take effect immediately. Reload privilege tables now? [Y/n] y ... Success! Cleaning up... All done! If you've completed all of the above steps, your MySQL installation should now be secure. Thanks for using MySQL! #

5）安装cloudstack数据库

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

[ OK ] Finalizing setup ... [ OK ] CloudStack has successfully initialized database, you can check your database configuration in /etc/cloudstack/management/db.properties #

9. 初始化cloudstack管理节点

1 2 3 4 5 6

# cloudstack-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!

10. 启动cloudstack-management

1	# service cloudstack-management start

11. 配置NFS存储，该内容可以独立配置。配置说明: 安装是主存储采用NFS进行测试，NFS可以由其它服务器单独提供，这里供测试，根据如下要求，在另一服务器及管理机上配置NFS服务。
NFS(辅助存储）: 192.168.10.180   
NFS(主存储)   : 192.168.10.185
1）配置域名(主要配合NFS配置使用)

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

2) 准备NFS目录

1	# mkdir -p /data/{primary,secondary}

3) 修改nfs服务参数

1 2 3 4 5 6 7 8

# vi /etc/sysconfig/nfs LOCKD_TCPPORT=32803 LOCKD_UDPPORT=32769 RQUOTAD_PORT=875 MOUNTD_PORT=892 STATD_PORT=662 STATD_OUTGOING_PORT=2020 RPCNFSDARGS="-N 4"

4）配置文件

1 2 3

# vi /etc/exports /data/primary *(rw,fsid=1,async,no_root_squash,no_subtree_check) /data/secondary *(rw,fsid=1,async,no_root_squash,no_subtree_check)

5) 配置nfs服务启动

1 2 3 4 5

service rpcbind start service nfs start chkconfig rpcbind on chkconfig nfs on showmount -e 127.0.0.1

6) 挂载测试，测试完毕后卸载掉，不需要手动挂载.

1 2 3 4 5 6 7 8 9 10

mount -t nfs 192.168.10.185:/data/primary /mnt/1/ mount -t nfs 192.168.10.180:/data/secondary /mnt/2/ # df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/vg_cloudstack-lv_root 36G 5.1G 29G 16% / tmpfs 1.9G 68K 1.9G 1% /dev/shm /dev/sda1 485M 39M 421M 9% /boot 192.168.10.185:/data/primary 36G 5.1G 29G 16% /mnt/1 192.168.10.180:/data/secondary 36G 6.1G 28G 19% /mnt/2 [iyunv@cloudstack mnt]#

注：CentOS6.5 NFS在配置的时出现过疑似BUG，同一服务器上两个输出目录，客户端挂载时挂载的是同一个目录，非两个不同目录，在如下/var/log/message日志中有证明。这就是我搞两个NFS服务器的原因。
Sep 19 15:05:59 cloudstack rpc.mountd[13097]: /data/primary and /data/secondary have same filehandle for *, using first
12. 导入系统虚拟机模板说明: 系统虚拟机模板按要求要存放在辅助存储上的，我们可以先手动挂载nfs辅助存储, 然后把290M KVM虚拟化模板先下载到辅助存储目录下，然后在导入, 导入系统虚拟机模板步是必须要配置的内容。本例采用KVM虚拟化，下载导入KVM虚拟机模板。

1 2 3 4 5 6 7 8

# mount -t nfs 192.168.10.180:/data/secondary /mnt/2/ # cd /mnt/2/ # wget http://cloudstack.apt-get.eu/sys ... 4.0-6-kvm.qcow2.bz2 # /usr/share/cloudstack-common/scripts/storage/secondary/cloud-install-sys-tmplt -m /mnt/2/ -f systemvm64template-4.4.0-6-kvm.qcow2.bz2 -h kvm -F Uncompressing to /usr/share/cloudstack-common/scripts/storage/secondary/e5a0ec24-0ae5-4740-8f54-94e08898a3c4.qcow2.tmp (type bz2)...could take a long time Moving to /data/secondary/template/tmpl/1/3///e5a0ec24-0ae5-4740-8f54-94e08898a3c4.qcow2...could take a while Successfully installed system VM template systemvm64template-4.4.0-6-kvm.qcow2.bz2 to /data/secondary/template/tmpl/1/3/ #

系统虚拟机默认用户名密码：root/6m1ll10n

13. 安装完成, 访问http://192.168.10.185:8080/client   
默认用户名和密码为admin, password

安装完毕。
