CloudStack 4.4学习总结之cloudstack-management安装

1、cloudstack-management安装步骤（CloudStack 3.0和4.4软件包）

CloudStack的3.0版本和4.4版本的命令和目录有很大的区别。

下面的命令，标注部分为3.0和4.4的区别，其他的不变。

①、以 root 身份登录并设置主机名：

主机名：【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、设置SELinux并同步时间：

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、安装MySQL：

这里将mysql单独拿出来安装，用的是光盘的yum源，可以节省资源，当然大家可以使用Cloudstack的安装脚本进行安装，一样的效果。

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，可直接全选Y

④、安装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”------> 安装 Management Server 软件。

“D”------> 安装 MySQL。

⑤、初始化CloudStack的数据库：

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 用户身份来生成数据库，该数据库属于新建的 cloud 用户（密码 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数据库的相关信息。

⑥、初始化cloudstack-management并启动：

对操作系统 iptables、sudoers 的设置（CloudStack 本身有安全性方面的要求，不是无限暴露给网络，同时又需要一些管理权限来运行自身服务，因此要做这两项的设置）。

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的日志文件：/var/log/cloud/management/management-server.log

⑦、配置NFS：

前面讲过，CloudStack 需要两类存储（primary storage 和 secondary storage）来支持它的 cluster 和 host，本节中由 NFS 来提供这两个存储，因此前述步骤中要启动 NFS 服务。同时为了方便起见，NFS Server 也由 cloud-server.perofu.com 充当。

yum install nfs-utils -y

mkdir -p /data/{primary,secondary} #创建两个目录，分别作为一级和二级存储

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 #导出/data 目录

cp /etc/sysconfig/nfs /etc/sysconfig/nfs.bak

> /etc/sysconfig/nfs

vi /etc/sysconfig/nfs #用于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，也可以关闭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 #管理服务器（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 #测试能否挂载，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

172.22.2.76:/data/primary 19G 1.7G 16G 10% /tmp/primarymount

⑧、导入虚拟机模板：

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）、在management上挂载辅助存储；

2）、下载kvm模板，并上传到辅助存储；

3）、导入。

systemvm64template-4.4.0-6-kvm.qcow2.bz2模板文件有点大，最好是通过别的下载工具进行下载，如百度网盘的离线下载，再上传使用。

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

系统虚拟机默认用户名密码：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
