CloudStack学习-2
环境准备
这次实验主要是CloudStack结合glusterfs。 两台宿主机,做gluster复制卷
VmWare添加一台和agent1配置一样的机器
系统版本:centos6.6 x86_64 内存:4GB 网络:机器是nat 磁盘:装完系统后额外添加个50GB的磁盘 额外:勾选vt-x
配置主机名为agent2
正式开始
关闭iptables和selinux
sed -i 's#SELINUX=enforcing#SELINUX=disabled#g' /etc/selinux/config setenforce 0 chkconfig iptables off /etc/init.d/iptables stop
配置IP地址为静态的
[root@agent2 ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0 DEVICE=eth0 TYPE=Ethernet ONBOOT=yes BOOTPROTO=static IPADDR=192.168.145.153 NETMASK=255.255.255.0 GATEWAY=192.168.145.2 DNS1=10.0.1.11 [root@agent2 ~]#
配置主机名为agent2
配置hosts文件
cat >>/etc/hosts<<EOF 192.168.145.151 master1 192.168.145.152 agent1 192.168.145.153 agent2 EOF
保证master和两台agent的配置都如下
[root@agent2 ~]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.145.151 master1 192.168.145.152 agent1 192.168.145.153 agent2 [root@agent2 ~]#
配置ntp
yum install ntp -y chkconfig ntpd on /etc/init.d/ntpd start
检查 hostname --fqdn
[root@agent2 ~]# hostname --fqdn agent2 [root@agent2 ~]#
安装epel源
yum install epel-release -y
agent2上也如下操作,注意agent2新建primary目录
[root@agent2 tools]# mkdir /export/primary -p [root@agent2 tools]#
agent2上操作,格式化磁盘
[root@agent2 ~]# mkfs.ext4 /dev/sdb mke2fs 1.41.12 (17-May-2010) /dev/sdb is entire device, not just one partition! Proceed anyway? (y,n) y Filesystem label= OS type: Linux Block size=4096 (log=2) Fragment size=4096 (log=2) Stride=0 blocks, Stripe width=0 blocks 3276800 inodes, 13107200 blocks 655360 blocks (5.00%) reserved for the super user First data block=0 Maximum filesystem blocks=4294967296 400 block groups 32768 blocks per group, 32768 fragments per group 8192 inodes per group Superblock backups stored on blocks: 32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208, 4096000, 7962624, 11239424 Writing inode tables: done Creating journal (32768 blocks): done Writing superblocks and filesystem accounting information: done This filesystem will be automatically checked every 36 mounts or 180 days, whichever comes first. Use tune2fs -c or -i to override. [root@agent2 ~]#
agent2上操作
[root@agent2 ~]# echo "/dev/sdb /export/primary ext4 defaults 0 0">>/etc/fstab [root@agent2 ~]# mount -a [root@agent2 ~]# df -h Filesystem Size Used Avail Use% Mounted on /dev/sda3 35G 2.3G 31G 7% / tmpfs 1.9G 0 1.9G 0% /dev/shm /dev/sda1 380M 33M 328M 9% /boot /dev/sdb 50G 52M 47G 1% /export/primary [root@agent2 ~]#
删除之前实验残留的配置
master端操作
删除之前的配置
先操作master,删除之前的库
[root@master1 ~]# mysql -uroot -p123456 Welcome to the MySQL monitor. Commands end with ; or \g.

停止management服务
[root@master1 ~]# /etc/init.d/cloudstack-management stop Stopping cloudstack-management: [FAILED] [root@master1 ~]# /etc/init.d/cloudstack-management stop Stopping cloudstack-management: [ OK ] [root@master1 ~]# /etc/init.d/cloudstack-management status cloudstack-management is stopped [root@master1 ~]#
agent1上卸载gluster的包
卸载glusterfs会卸载kvm相关的依赖包,从c6.6开始的
6.5以前,kvm也不依赖glusterfs
如果replication包没安装的话,先执行上面的卸载操作
它会自动的把kvm的包卸载。libvirtd的包也被卸载
[root@agent1 ~]# rpm -qa | grep gluster [root@agent1 ~]# yum remove glusterfs* [root@agent1 ~]# rpm -qa | grep kvm [root@agent1 ~]# rpm -qa | grep libvirt libvirt-python-0.10.2-60.el6.x86_64 libvirt-client-0.10.2-60.el6.x86_64 [root@agent1 ~]#
小插曲
agent1本次实验完毕关机后,ifcfg-cloudbr0文件没生成。在这之前实验是正常的,重启后发现cloudbr0文件丢失 解决办法:复制ifcfg-eth0为ifcfg-cloudbr0,参照机器agent2上正常的cloudbr0文件修改
配置glusterfs
安装gluster3.7的源(agent1和agent2都操作)
如果你安装了3.6和3.8的包也没问题
[root@agent1 ~]# yum install centos-release-gluster37 -y Loaded plugins: fastestmirror, security Setting up Install Process Loading mirror speeds from cached hostfile * epel: mirrors.tuna.tsinghua.edu.cn centos-gluster37 | 2.9 kB 00:00 centos-gluster37/primary_db | 99 kB 00:07 Package centos-release-gluster37-1.0-4.el6.centos.noarch already installed and latest version Nothing to do [root@agent1 ~]#
查看yum源文件
[root@agent1 ~]# cat /etc/yum.repos.d/CentOS-Gluster-3.7.repo # CentOS-Gluster-3.7.repo # # Please see http://wiki.centos.org/SpecialInterestGroup/Storage for more # information [centos-gluster37] name=CentOS-$releasever - Gluster 3.7 baseurl=http://mirror.centos.org/centos/$releasever/storage/$basearch/gluster-3.7/ gpgcheck=1 enabled=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-SIG-Storage [centos-gluster37-test] name=CentOS-$releasever - Gluster 3.7 Testing baseurl=http://buildlogs.centos.org/centos/$releasever/storage/$basearch/gluster-3.7/ gpgcheck=0 enabled=0 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-SIG-Storage [root@agent1 ~]#
指定源,安装对应版本的glusterfs包(agent1和agent2都操作)
[root@agent1 ~]# yum --enablerepo=centos-gluster37-test install glusterfs-server glusterfs-cli gluster-geo-replication -y
也可以从下面路径下载rpm包,然后安装
https://download.gluster.org/pub/gluster/glusterfs/3.7/LATEST/CentOS/epel-6.8/x86_64/
agent端删除之前残留文件
agent1删除挂载点原先的文件(原先的kvm等文件)
[root@agent1 ~]# cd /export/primary/ [root@agent1 primary]# ls 0cc65968-4ff3-4b4c-b31e-7f1cf5d1959b cf3dac7a-a071-4def-83aa-555b5611fb02 1685f81b-9ac9-4b21-981a-f1b01006c9ef f3521c3d-fca3-4527-984d-5ff208e05b5c 99643b7d-aaf4-4c75-b7d6-832c060e9b77 lost+found [root@agent1 primary]# rm -rf * [root@agent1 primary]# ls [root@agent1 primary]#
agent2也如此操作。删除多余的东西
[root@agent2 ~]# cd /export/primary/ [root@agent2 primary]# ls lost+found [root@agent2 primary]# rm -rf * [root@agent2 primary]# ls [root@agent2 primary]#
agent2上安装CloudStack包(在这之前,已经把glusterfs3.7的包安装上了)
这些agent不需要手动起,它们是交给master管理的
其实master是通过22端口连接过来管理的
[root@agent2 tools]# yum install cloudstack-agent-4.8.0-1.el6.x86_64.rpm cloudstack-common-4.8.0-1.el6.x86_64.rpm -y
agent端检查glusterfs版本
[root@agent1 ~]# glusterfs -V glusterfs 3.7.20 built on Jan 30 2017 15:39:27 Repository revision: git://git.gluster.com/glusterfs.git Copyright (c) 2006-2013 Red Hat, Inc. <http://www.redhat.com/> GlusterFS comes with ABSOLUTELY NO WARRANTY.

[root@agent1 ~]#
启动glusterd并设置开机启动(两个agent上操作)
[root@agent1 ~]# /etc/init.d/glusterd start Starting glusterd: [ OK ] [root@agent1 ~]# chkconfig glusterd on [root@agent1 ~]#
两台agent停止iptables
[root@agent1 ~]# /etc/init.d/iptables stop iptables: Setting chains to policy ACCEPT: nat mangle filte[ OK ] iptables: Flushing firewall rules: [ OK ] iptables: Unloading modules: [ OK ] [root@agent1 ~]# chkconfig iptables off [root@agent1 ~]#
gluster加入节点,并检查状态,在一台agent上操作即可
[root@agent1 ~]# gluster peer probe agent2 peer probe: failed: Probe returned with Transport endpoint is not connected [root@agent1 ~]# gluster peer probe agent2 peer probe: success. [root@agent1 ~]# gluster peer status Number of Peers: 1 Hostname: agent2 Uuid: 2778cb7a-32ef-4a3f-a34c-b97f5937bb49 State: Peer in Cluster (Connected) [root@agent1 ~]#
创建复制卷
开始操作
gv2是自定义的
[root@agent1 ~]# gluster volume create gv2 replica 2 agent1:/export/primary agent2:/export/primary force volume create: gv2: success: please start the volume to access data [root@agent1 ~]#
启动这个卷,并查看状态,Type显示Replicate,就表示复制卷的意思 ,为什么采用gluster呢,原先主存储是本地挂载的,假如宿主机挂掉后,宿主机上的kvm全部挂掉。
[root@agent1 ~]# gluster volume start gv2 volume start: gv2: success [root@agent1 ~]# gluster volume info Volume Name: gv2 Type: Replicate Volume ID: 3a23ab68-73da-4f1b-bc5c-3310ffa9e8b7 Status: Started Number of Bricks: 1 x 2 = 2 Transport-type: tcp Bricks: Brick1: agent1:/export/primary Brick2: agent2:/export/primary Options Reconfigured: performance.readdir-ahead: on [root@agent1 ~]#
gluster的东西至此完毕,继续之前的内容
CloudStack配置和用户界面操作
继续在master上如下初始化数据库的操作,导入数据
[root@master1 ~]# cloudstack-setup-databases cloud:123456@localhost --deploy-as=root:123456 Mysql user name:cloud [ OK ] Mysql user password:****** [ OK ] Mysql server ip:localhost [ OK ] Mysql server port:3306 [ OK ] Mysql root user name:root [ OK ] Mysql root user password:****** [ OK ] Checking Cloud database files ...

[ OK ] Finalizing setup ... [ OK ] CloudStack has successfully initialized database, you can check your database configuration in /etc/cloudstack/management/db.properties [root@master1 ~]#
数据库配置完毕后,启动master,它会做一些初始化的操作
以后不要这么启动,初始化只执行一次就行了
[root@master1 ~]# cloudstack-setup-management
查看日志,已经启动完成了,看到8080端口已经监听了
[root@master1 ~]# tail -f /var/log/cloudstack/management/catalina.out INFO [o.a.c.s.l.CloudStackExtendedLifeCycle] (main:ctx-d2bdddaf) (logid:) Done Configuring CloudStack Components INFO [c.c.u.LogUtils] (main:ctx-d2bdddaf) (logid:) log4j configuration found at /etc/cloudstack/management/log4j-cloud.xml Feb 12, 2017 7:59:25 PM org.apache.coyote.http11.Http11NioProtocol start INFO: Starting Coyote HTTP/1.1 on http-8080 Feb 12, 2017 7:59:25 PM org.apache.jk.common.ChannelSocket init INFO: JK: ajp13 listening on /0.0.0.0:20400 Feb 12, 2017 7:59:25 PM org.apache.jk.server.JkMain start INFO: Jk running ID=0 time=0/18 config=null Feb 12, 2017 7:59:25 PM org.apache.catalina.startup.Catalina start INFO: Server startup in 63790 ms
登录网页
http://192.168.145.151:8080/client

admin/password
接下来创建系统虚拟机(master上操作)
系统虚拟路由,vnc窗口都是这些虚拟机的作用,master上执行下面命令
/usr/share/cloudstack-common/scripts/storage/secondary/cloud-install-sys-tmplt \ -m /export/secondary \ -f /tools/systemvm64template-4.6.0-kvm.qcow2.bz2 \ -h kvm -F
这个步骤的作用就是把虚拟机模板导入到二级存储,执行过程如下
[root@master1 tools]# /usr/share/cloudstack-common/scripts/storage/secondary/cloud-install-sys-tmplt \ > -m /export/secondary \ > -f /tools/systemvm64template-4.6.0-kvm.qcow2.bz2 \ > -h kvm -F Uncompressing to /usr/share/cloudstack-common/scripts/storage/secondary/9824edc4-61db-4ad8-a08a-61f051b9ebfe.qcow2.tmp (type bz2)...could take a long time Moving to /export/secondary/template/tmpl/1/3///9824edc4-61db-4ad8-a08a-61f051b9ebfe.qcow2...could take a while Successfully installed system VM template /tools/systemvm64template-4.6.0-kvm.qcow2.bz2 to /export/secondary/template/tmpl/1/3/ [root@master1 ~]#
登录CloudStack管理页面,更改内存的超配
改完需要重启下服务。

可以通过主机界面添加
添加成功
agent1没添加成功是上节课的cloudbr0 残留引起的
删除cloudbr0,重启agent1网络,再次master上添加,完成
[root@agent1 ~]# cd /etc/sysconfig/network-scripts/ [root@agent1 network-scripts]# ls ifcfg-cloudbr0 ifcfg-cloudbr0 [root@agent1 network-scripts]# rm -f ifcfg-cloudbr0 [root@agent1 network-scripts]# /etc/init.d/network restart Shutting down interface eth0: [ OK ] Shutting down loopback interface: [ OK ] Bringing up loopback interface: [ OK ] Bringing up interface eth0: [ OK ] [root@agent1 network-scripts]#
rm -f ifcfg-cloudbr0 /etc/init.d/network restart
ps -ef | grep kvm lsmod | grep kvm rpm -qa | grep kvm virsh list --all
cd /tools/ ls yum install cloudstack-agent-4.8.0-1.el6.x86_64.rpm cloudstack-common-4.8.0-1.el6.x86_64.rpm -y ps -ef | grep kvm lsmod | grep kvm rpm -qa | grep kvm /etc/init.d/libvirtd status /etc/init.d/libvirtd restart
virsh list ps -ef | grep kvm kill -9 2776 ps -ef | grep kvm kill -9 2532 ps -ef | grep kvm kill -9 2304 ps -ef | grep kvm virsh list --all
日志在刷,卡在这里,这里是别人做实验遇到的。就是cloudbr0文件没删除导致的
提示File exists
添加存储
先添加主存储

启动域之前,先优化一下
修改超配
关于超配可以参照上一节课的。
修改完之后需要重启master的management服务,可能服务第一次重启需要等待一段时间,为了确保成功,再次执行一次重启
[root@master1 ~]# /etc/init.d/cloudstack-management restart Stopping cloudstack-management: [FAILED] Starting cloudstack-management: [ OK ] [root@master1 ~]# /etc/init.d/cloudstack-management restart Stopping cloudstack-management: [ OK ] Starting cloudstack-management: [ OK ] [root@master1 ~]#

想判断kvm有没有启动成功,两种方法
1、网页查看
2、vnc登录看看
网页方式查看
启动中
![](https://images2015.cnblogs.com/blog/1076878/201702/1076878-20170213103756660-414826741.png)
