下載軟件包
從官網可以下載下面rpm包
http://cloudstack.apt-get.eu/centos/6/4.8/
master和agent都需要rpm包，注意路徑，這里的6是centos6系統，4.8是Cloudstack的版本號
usage這個包用於計費監控的，這里用不到
cli是調用亞馬遜aws接口之類的包，這里用不到
實驗這里只用到了management，common，agent這3個包
下載如下包 cloudstack-agent-4.8.0-1.el6.x86_64.rpm cloudstack-baremetal-agent-4.8.0-1.el6.x86_64.rpm cloudstack-cli-4.8.0-1.el6.x86_64.rpm cloudstack-common-4.8.0-1.el6.x86_64.rpm cloudstack-management-4.8.0-1.el6.x86_64.rpm cloudstack-usage-4.8.0-1.el6.x86_64.rpm
操作命令如下
[root@master1 ~]# mkdir /tools [root@master1 ~]# cd /tools/ wget http://cloudstack.apt-get.eu/centos/6/4.8/cloudstack-agent-4.8.0-1.el6.x86_64.rpm wget http://cloudstack.apt-get.eu/centos/6/4.8/cloudstack-baremetal-agent-4.8.0-1.el6.x86_64.rpm wget http://cloudstack.apt-get.eu/centos/6/4.8/cloudstack-cli-4.8.0-1.el6.x86_64.rpm wget http://cloudstack.apt-get.eu/centos/6/4.8/cloudstack-common-4.8.0-1.el6.x86_64.rpm wget http://cloudstack.apt-get.eu/centos/6/4.8/cloudstack-management-4.8.0-1.el6.x86_64.rpm wget http://cloudstack.apt-get.eu/centos/6/4.8/cloudstack-usage-4.8.0-1.el6.x86_64.rpm
下載kvm模板，這里只有master需要下載這個模板，它是系統虛擬機使用的
systemvm64template-2016-05-18-4.7.1-kvm.qcow2.bz2
http://cloudstack.apt-get.eu/systemvm/4.6/ http://cloudstack.apt-get.eu/systemvm/4.6/systemvm64template-4.6.0-kvm.qcow2.bz2
正式開始
關閉iptables和selinux
sed -i 's#SELINUX=enforcing#SELINUX=disabled#g' /etc/selinux/config setenforce 0 chkconfig iptables off /etc/init.d/iptables stop
兩台機器配置IP地址為靜態的
[root@master1 ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0 DEVICE=eth0 TYPE=Ethernet ONBOOT=yes BOOTPROTO=static IPADDR=192.168.145.151 NETMASK=255.255.255.0 GATEWAY=192.168.145.2 DNS1=10.0.1.11 [root@master1 ~]# [root@agent1 ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0 DEVICE=eth0 TYPE=Ethernet ONBOOT=yes BOOTPROTO=static IPADDR=192.168.145.152 NETMASK=255.255.255.0 GATEWAY=192.168.145.2 DNS1=10.0.1.11 [root@agent1 ~]#
配置主機名分別為master1和agent1
配置hosts文件 cat >>/etc/hosts<<EOF 192.168.145.151 master1 192.168.145.152 agent1 EOF
配置ntp
yum install ntp -y chkconfig ntpd on /etc/init.d/ntpd start
檢查 hostname --fqdn
[root@master1 ~]# hostname --fqdn master1 [root@master1 ~]# [root@agent1 ~]# hostname --fqdn agent1 [root@agent1 ~]#
兩台機器安裝epel源，默認的163的源可以下載epel源
yum install epel-release -y
master端安裝nfs
它也會自動把依賴的rpcbind安裝上
nfs 作為二級存儲，給agent提供虛擬機iso文件，存儲快照的地方
yum install nfs-utils -y
master端配置nfs，給agent宿主機當二級存儲使用
[root@master1 ~]# cat /etc/exports /export/secondary *(rw,async,no_root_squash,no_subtree_check) [root@master1 ~]#
master創建掛載目錄
[root@master1 ~]# mkdir /export/secondary -p [root@master1 ~]#
agent上也如下操作，注意agent新建primary目錄
[root@agent1 ~]# mkdir /export/primary -p [root@agent1 ~]#
格式化磁盤
master上操作，這里不分區了

配置nfs和iptables
先打開官方文檔配置nfs和iptables等
http://docs.cloudstack.apache.org/projects/cloudstack-installation/en/4.9/qig.html
有些企業可以關閉iptables，有些企業需要開啟，這里我們按照開啟的配置，來配置nfs
centos6.x 配置nfs添加如下參數，默認有這些參數，只是被注釋了。這里我們直接添加到文件最后即可
這個工作在master上操作
LOCKD_TCPPORT=32803 LOCKD_UDPPORT=32769 MOUNTD_PORT=892 RQUOTAD_PORT=875 STATD_PORT=662 STATD_OUTGOING_PORT=2020
這里我們直接添加到文件最后即可
[root@master1 ~]# vim /etc/sysconfig/nfs [root@master1 ~]# tail -10 /etc/sysconfig/nfs # # To enable RDMA support on the server by setting this to # the port the server should listen on #RDMA_PORT=20049 LOCKD_TCPPORT=32803 LOCKD_UDPPORT=32769 MOUNTD_PORT=892 RQUOTAD_PORT=875 STATD_PORT=662 STATD_OUTGOING_PORT=2020 [root@master1 ~]#
前后對比
master上操作的
[root@master1 tools]# cat /etc/sysconfig/iptables # Firewall configuration written by system-config-firewall # Manual customization of this file is not recommended. *filter :INPUT ACCEPT [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT -A INPUT -p icmp -j ACCEPT -A INPUT -i lo -j ACCEPT -A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT -A INPUT -j REJECT --reject-with icmp-host-prohibited -A FORWARD -j REJECT --reject-with icmp-host-prohibited COMMIT [root@master1 tools]# vim /etc/sysconfig/iptables
添加如下
多加了一條80的。為了避免以后再配置，這個80個nfs無關，是后面提供http方式的鏡像源使用

如果沒有showmount命令需要安裝nfs包
yum install nfs-utils -y
查看對方是否提供了nfs服務
[root@agent1 ~]# showmount -e 192.168.145.151 Export list for 192.168.145.151: /export/secondary * [root@agent1 ~]#
測試下可否掛載

安裝和配置Cloudstack
管理服務器端安裝，master上操作
[root@master1 tools]# ls cloudstack-agent-4.8.0-1.el6.x86_64.rpm cloudstack-baremetal-agent-4.8.0-1.el6.x86_64.rpm cloudstack-cli-4.8.0-1.el6.x86_64.rpm cloudstack-common-4.8.0-1.el6.x86_64.rpm cloudstack-management-4.8.0-1.el6.x86_64.rpm cloudstack-usage-4.8.0-1.el6.x86_64.rpm systemvm64template-4.6.0-kvm.qcow2.bz2 [root@master1 tools]# yum install -y cloudstack-management-4.8.0-1.el6.x86_64.rpm cloudstack-common-4.8.0-1.el6.x86_64.rpm [root@master1 tools]# rpm -qa | grep cloudstack cloudstack-common-4.8.0-1.el6.x86_64 cloudstack-management-4.8.0-1.el6.x86_64 [root@master1 tools]#
在master上安裝mysql-server
[root@master1 tools]# yum install mysql-server -y
修改mysql配置文件添加參數
在[mysqld]模塊下
添加下面參數
innodb_rollback_on_timeout=1 innodb_lock_wait_timeout=600 max_connections=350 log-bin=mysql-bin binlog-format = 'ROW'
最終結果如下
[root@master1 tools]# vim /etc/my.cnf [root@master1 tools]# cat /etc/my.cnf [mysqld] datadir=/var/lib/mysql socket=/var/lib/mysql/mysql.sock user=mysql # Disabling symbolic-links is recommended to prevent assorted security risks symbolic-links=0 innodb_rollback_on_timeout=1 innodb_lock_wait_timeout=600 max_connections=350 log-bin=mysql-bin binlog-format = 'ROW' [mysqld_safe] log-error=/var/log/mysqld.log pid-file=/var/run/mysqld/mysqld.pid [root@master1 tools]#
啟動mysql服務並設置開機啟動
[root@master1 tools]# service mysqld start
Initializing MySQL database: Installing MySQL system tables...
OK
Filling help tables...
OK
To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system
PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
/usr/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h master1 password 'new-password'
Alternatively you can run:
/usr/bin/mysql_secure_installation
which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers.
See the manual for more instructions.
You can start the MySQL daemon with:
cd /usr ; /usr/bin/mysqld_safe &
You can test the MySQL daemon with mysql-test-run.pl
cd /usr/mysql-test ; perl mysql-test-run.pl
Please report any problems with the /usr/bin/mysqlbug script!
[ OK ]
Starting mysqld: [ OK ]
[root@master1 tools]# chkconfig mysqld on
[root@master1 tools]#
[root@master1 tools]# ls /var/lib/mysql/
ibdata1 ib_logfile0 ib_logfile1 mysql mysql.sock test
[root@master1 tools]#
給mysql設置密碼，第一個是localhost的，第二個是可以遠程登錄的
[root@master1 tools]# /usr/bin/mysqladmin -u root password '123456' [root@master1 tools]# mysql -uroot -p123456 -e "grant all on *.* to root@'%' identified by '123456';" [root@master1 tools]#
master端初始化Cloudstack的數據庫
這個命令其實是導入數據到mysql庫（在master上操作），執行腳本創建庫和表
[root@master1 tools]# 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 ...

初始化完畢
下面文件是初始化之后，自動改動的。我們可以查看下，里面的東西不需要改動了
[root@master1 tools]# vim /etc/cloudstack/management/db.properties [root@master1 tools]#
啟動master，輸入cl按tab鍵可以看到很多命令
[root@master1 tools]# cl clean-binary-files cloudstack-set-guest-sshkey clear cloudstack-setup-databases clock cloudstack-setup-encryption clockdiff cloudstack-setup-management cloudstack-external-ipallocator.py cloudstack-sysvmadm cloudstack-migrate-databases cloudstack-update-xenserver-licenses cloudstack-sccs cls cloudstack-set-guest-password [root@master1 tools]# cloudstack-setup-management Starting to configure CloudStack Management Server: Configure Firewall ...

你的master防火牆配置好了，這個啟動它會再起來，加入一些自己的端口，比如下面。多了9090，8250,8080端口
[root@master1 tools]# head -10 /etc/sysconfig/iptables # Generated by iptables-save v1.4.7 on Sat Feb 11 20:07:43 2017 *filter :INPUT ACCEPT [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] -A INPUT -p tcp -m tcp --dport 9090 -j ACCEPT -A INPUT -p tcp -m tcp --dport 8250 -j ACCEPT -A INPUT -p tcp -m tcp --dport 8080 -j ACCEPT -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT -A INPUT -p icmp -j ACCEPT [root@master1 tools]#
下面是它的日志，因為它底層是tomcat，日志是一致的
master最好是16GB內存。提供足夠內存給jvm，這樣服務啟動才快。
[root@master1 tools]# tail -f /var/log/cloudstack/management/catalina.out INFO [o.a.c.f.j.i.AsyncJobManagerImpl] (AsyncJobMgr-Heartbeat-1:ctx-2f0e1bd5) (logid:4db872cc) Begin cleanup expired async-jobs INFO [o.a.c.f.j.i.AsyncJobManagerImpl] (AsyncJobMgr-Heartbeat-1:ctx-2f0e1bd5) (logid:4db872cc) End cleanup expired async-jobs INFO [o.a.c.f.j.i.AsyncJobManagerImpl] (AsyncJobMgr-Heartbeat-1:ctx-fc8583d4) (logid:8724f870) Begin cleanup expired async-jobs INFO [o.a.c.f.j.i.AsyncJobManagerImpl] (AsyncJobMgr-Heartbeat-1:ctx-fc8583d4) (logid:8724f870) End cleanup expired async-jobs

打開管理頁面，說明master端安裝完畢
導入系統虛擬機鏡像
CloudStack通過一系列系統虛擬機提供功能，如訪問虛擬機控制台，如提供各類
網絡服務，以及管理輔助存儲中的各類資源。
下面是導入系統虛擬機模板，並把這些模板部署於剛才創建的輔助存儲中：管理服務器
包含一個腳本可以正確的操作這些系統虛擬機模板
先找到虛擬機模板路徑
[root@master1 tools]# ls /tools/systemvm64template-4.6.0-kvm.qcow2.bz2 /tools/systemvm64template-4.6.0-kvm.qcow2.bz2
master上執行下面命令
/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
這個步驟的作用就是把虛擬機模板導入到二級存儲，執行過程如下
[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/0cc65968-4ff3-4b4c-b31e-7f1cf5d1959b.qcow2.tmp (type bz2)...could take a long time Moving to /export/secondary/template/tmpl/1/3///0cc65968-4ff3-4b4c-b31e-7f1cf5d1959b.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 tools]#
導入成功后，模板會在這里，一個模板和一個模板配置文件
[root@master1 tools]# cd /export/secondary/ [root@master1 secondary]# ls lost+found template [root@master1 secondary]# cd template/tmpl/1/3/ [root@master1 3]# ls 0cc65968-4ff3-4b4c-b31e-7f1cf5d1959b.qcow2 template.properties [root@master1 3]# ls 0cc65968-4ff3-4b4c-b31e-7f1cf5d1959b.qcow2 template.properties [root@master1 3]# pwd /export/secondary/template/tmpl/1/3 [root@master1 3]#
這個是模板的配置，不用修改
[root@master1 3]# cat template.properties filename=0cc65968-4ff3-4b4c-b31e-7f1cf5d1959b.qcow2 description=SystemVM Template checksum= hvm=false size=322954240 qcow2=true id=3 public=true qcow2.filename=0cc65968-4ff3-4b4c-b31e-7f1cf5d1959b.qcow2 uniquename=routing-3 qcow2.virtualsize=322954240 virtualsize=322954240 qcow2.size=322954240 [root@master1 3]#
agent安裝Cloudstack包
agent端如下操作
[root@agent1 tools]# yum install cloudstack-common-4.8.0-1.el6.x86_64.rpm cloudstack-agent-4.8.0-1.el6.x86_64.rpm -y
它會依賴qemu-kvm，libvirt和glusterfs 這些包都會自動安裝上
glusterfs已經默認作為kvm的后端存儲了
[root@agent1 ~]# rpm -qa | egrep "cloudstack|gluster|kvm|libvirt" glusterfs-client-xlators-3.7.5-19.el6.x86_64 cloudstack-common-4.8.0-1.el6.x86_64 cloudstack-agent-4.8.0-1.el6.x86_64 glusterfs-libs-3.7.5-19.el6.x86_64 glusterfs-3.7.5-19.el6.x86_64 glusterfs-api-3.7.5-19.el6.x86_64 libvirt-python-0.10.2-60.el6.x86_64 libvirt-0.10.2-60.el6.x86_64 libvirt-client-0.10.2-60.el6.x86_64 qemu-kvm-0.12.1.2-2.491.el6_8.3.x86_64 [root@agent1 ~]#
Agent端虛擬化配置
配置KVM
KVM中我們有兩部分需要進行配置，libvirt和qemu
配置qemu
KVM的配置相對簡單，只需要配置一項，編輯/etc/libvirt/qemu.conf
取消vnc_listen=0.0.0.0的注釋，同時注釋掉security_driver="none"
由於security_driver默認是如下注釋狀態。#security_driver = "selinux"
這里就不改它了。只取消vnc_listen=0.0.0.0的注釋
（有人說加入主機會自動修改這些參數。我未驗證，直接手動修改）
配置Libvirt
Cloudstack通過調用libvirt管理虛擬機。
為了實現動態遷移，libvirt需要監聽使用非加密的TCP連接。還需要關閉嘗試
使用組播DNS進行廣播。這些都在/etc/libvirt/libvirtd.conf文件中進行配置
（有人說加入主機會自動修改這些參數。我未驗證，直接手動修改）
設置下列參數
這些參數它是讓我們取消注釋，我們直接加入到最后就行了（agent上操作）
listen_tls = 0 listen_tcp = 1 tcp_port = "16059" auth_tcp = "none" mdns_adv = 0
修改命令如下
cat>>/etc/libvirt/libvirtd.conf<<EOF listen_tls = 0 listen_tcp = 1 tcp_port = "16059" auth_tcp = "none" mdns_adv = 0 EOF
操作過程如下
[root@agent1 tools]# cat>>/etc/libvirt/libvirtd.conf<<EOF > listen_tls = 0 > listen_tcp = 1 > tcp_port = "16059" > auth_tcp = "none" > mdns_adv = 0 > EOF [root@agent1 tools]# tail -5 /etc/libvirt/libvirtd.conf listen_tls = 0 listen_tcp = 1 tcp_port = "16059" auth_tcp = "none" mdns_adv = 0 [root@agent1 tools]#
還要取消下面文件中注釋
/etc/sysconfig/libvirtd
#LIBVIRTD_ARGS="--listen"
文檔上是取消注釋，我們這里改成-l 注意這里是listen的l，是字母，不是數字1
LIBVIRTD_ARGS="-1"
（有人說加入主機會自動修改這些參數。我未驗證，直接手動修改）
查看檢驗
[root@agent1 tools]# grep LIBVIRTD_ARGS /etc/sysconfig/libvirtd # in LIBVIRTD_ARGS instead. LIBVIRTD_ARGS="-1" [root@agent1 tools]#
重啟libvirt服務，查看kvm模塊是否有加載
[root@agent1 tools]# /etc/init.d/libvirtd restart Stopping libvirtd daemon: [ OK ] Starting libvirtd daemon: [ OK ] [root@agent1 tools]# lsmod | grep kvm kvm_intel 55496 0 kvm 337772 1 kvm_intel [root@agent1 tools]#
KVM部分配置完成
用戶界面操作
默認密碼是admin/password
用戶界面語言可以選擇簡體中文
IE瀏覽器打開下面地址
http://192.168.145.151:8080/client/
CloudStack提供一個基於Web的UI，管理員和終端用戶能夠使用這個界面。用戶界面版本
依賴於登錄時使用的憑證不同而不同。用戶界面是適用於大多數流行的瀏覽器。包括IE7
IE8，IE9，Firefox，chrome等
登錄地址如下
http://management-server-ip:8080/client/
admin/password
可以選擇語言
登錄進去。顯示如下
用戶界面的配置
網頁上點擊跳過此步驟
點擊右邊的添加資源域
選擇基本網絡
dns這里我們都可以寫成公共的dns服務器（我們沒自己搭建dns）
我本地局域網友dns，這里就寫成了本地dns服務器
網絡就選擇默認的第一個就行了
下一步
這里就輸入eth0
（高級玩法里面還分存儲網絡，管理網絡和來賓網絡）
編輯下面的管理和來賓，標簽這里都寫成cloudbr0
點擊下一步
網關寫上面的這些信息
預留的IP這里，是給系統虛擬機和宿主機用的
這個是給普通kvm使用的，創建的客戶kvm使用的
集群名稱自定義
這里的主機就是agent的那個
root/root01
主存儲這里支持很多協議。RBD和Gluster自己可以百度下作用
RBD是safe
nfs的話，機器掛了。所有kvm都掛了
如果用了glusterfs掛了。可以使用其它節點起來。（復制卷）
我們這里設置為自己的共享掛載點/export/primary
最終填寫結果如下，下一步
有時間可以百度下，下面東西都是什么
s3是亞馬遜aws的雲存儲
二級存儲這里最終的選擇如下
點擊啟動
初始化過程比較慢
可以先點否，手動啟用資源域
啟動資源域
啟動資源域后系統會創建兩個虛擬機
console proxy vm是你虛擬機的vnc的代理服務的機器
secondary storage vm是你虛擬機鏡像的機器，通過它取到鏡像
啟動資源域之后
登錄agent上查看2個系統虛擬機

系統VM是不同於主機上創建的普通虛擬機，它們是CloudStack雲平台自帶的用於完成自身的一些任務的虛擬機
1、Seondary Storage VM：簡稱SSVM，用於管理二級存儲的相關操作，如模板根鏡像文件的
上傳與下載，快照，volumes的存放，第一次創建虛擬機時從二級存儲拷貝模板到一級存儲並且
自動創建快照，每一個資源域可以有多個SSVM，當SSVM被刪除或停止，它會自動被重建並啟動
2、ConsolePorxy VM：用於web界面展示控制台
3、虛擬路由器：將會在第一個實例啟動后自動創建
兩台虛擬機可以查看控制台
默認的用戶名和密碼root/password
167是pod網絡，179是來賓網絡

虛擬路由器將會在第一個實例啟動后自動創建
模板這里有個centos5.5，目前是無法使用的
要把它打開
我們允許都可以訪問
提示重啟服務才生效，我們重啟，它會從網上下載5.5的鏡像源
[root@master1 3]# /etc/init.d/cloudstack-management restart Stopping cloudstack-management: [FAILED] Starting cloudstack-management: [ OK ] [root@master1 3]# [root@master1 3]# [root@master1 3]# /etc/init.d/cloudstack-management restart Stopping cloudstack-management: [ OK ] Starting cloudstack-management: [ OK ] [root@master1 3]#
以上修改，它就自動下載自帶的模板了
模板可以通過本地上傳，也可以添加
注意本地上傳暫時有bug。
重新登錄網頁
對於一些情況，資源域資源告警時可能無法創建虛擬機。我們可以調整參數，讓其超配
改成3
mem.overprovisioning.factor
內存超配倍數，內存可用量=內存總量*超配倍數；類型：整數；默認：1（不超配）
下面兩個網站關於全局設置的意思可以看看
http://www.chinacloudly.com/cloudstack%E5%85%A8%E5%B1%80%E9%85%8D%E7%BD%AE%E5%8F%82%E6%95%B0/
http://blog.csdn.net/u011650565/article/details/41945433
重啟management服務，登錄這里沒變
然后點擊基礎架構---集群----cluster--設置
找到下面，
也改成3.0
告警設置
允許的利用率，下面的0.85可以改成0.99，因為達到0.85的情況下不允許創建虛擬機了
這里就變了，我的虛擬機沒8GB，這里就是超配了
制作模板和創建自定義虛擬機
CloudStack模板支持兩種模式
1、通過kvm制作的qcow2或者raw文件
2、直接上傳iso文件作為模板文件
由於國內nginx比較流行，我們這里使用nginx搭建鏡像源
[root@master1 ~]# yum install nginx -y
防火牆我們前期做了，其實也可以把它關閉了
實際環境中，最好另外搭建一台nginx服務器，盡量減輕master的壓力
[root@master1 ~]# /etc/init.d/iptables stop
啟動nginx
[root@master1 ~]# /etc/init.d/nginx start Starting nginx: [ OK ] [root@master1 ~]#
瀏覽器輸入master的地址，也就是nginx安裝的服務器的地址
http://192.168.145.151/
編輯配置文件，讓它成為目錄服務器
這個access_log下面添加
access_log /var/log/nginx/access.log main;
autoindex on; #顯示目錄
autoindex_exact_size on; #顯示文件大小
autoindex_localtime on; #顯示文件時間
確認下，可以把漢字刪除，防止一些可能的報錯
[root@master1 ~]# sed -n '23,26p' /etc/nginx/nginx.conf
access_log /var/log/nginx/access.log main;
autoindex on;
autoindex_exact_size on;
autoindex_localtime on;
[root@master1 ~]#
檢查語法，重啟nginx
[root@master1 ~]# /etc/init.d/nginx configtest nginx: the configuration file /etc/nginx/nginx.conf syntax is ok nginx: configuration file /etc/nginx/nginx.conf test is successful [root@master1 ~]# /etc/init.d/nginx restart Stopping nginx: [ OK ] Starting nginx: [ OK ] [root@master1 ~]#
到/usr/share/nginx/html 目錄下，刪除所有文件，
上傳iso文件到/usr/share/nginx/html 下面
這里我們上傳CentOS-6.5-x86_64-minimal.iso
[root@master1 tools]# cd /usr/share/nginx/html/ [root@master1 html]# ls 404.html 50x.html index.html nginx-logo.png poweredby.png [root@master1 html]# rm -rf * [root@master1 html]# mv /tools/CentOS-6.5-x86_64-minimal.iso . [root@master1 html]# ls CentOS-6.5-x86_64-minimal.iso [root@master1 html]#
再次刷新nginx首頁
http://192.168.145.151/
網頁操作，添加iso
它會自動從服務器上下載
自己下載到自己上，肯定速度很快
創建自定義虛擬機實例
這里可以選擇20GB
關聯性默認
網絡默認
名稱這里如果你不寫，它會自動生成64位的一個uuid
點擊啟動
創建中，第一次創建比較慢，它要從二級存儲，也就是nfs服務器拿到主存儲上，所以比較慢
創建第二個虛擬機的時候比較快
打開實例的控制台
選最后一個
root01
virtio已經是頁面標識了，紅帽現在全力支持kvm了
c6已經集成到內核了
安裝過程
點擊reboot之后，這里取消附件iso，防止重復安裝
機器裝好之后，reboot，同時盡快取消iso，否則又從iso創建了
設置網卡onboot=yes
安裝新的實例后，虛擬路由器這里也變了
生產中，一般一個集群是8-16台或者24台主機
2個機櫃的服務器，這么划分比較合理
超過24台你可以添加另一個集群，cluster2
agent機器上輸入ip a
看到cloudbr0就是我們創建的網橋
vnet0就是虛擬設備
虛擬機連接到vnet設備，vnet又接到網橋上
