一 环境准备

1.1 操作系统部署

部署操作系统Centos 7，本次选择Centos 7.9

执行yum update -y # 升级所有包同时也升级软件和系统内核

重启服务器

1.2 设置网络和主机名

[root@openstack ~]# cat /etc/hosts
# 127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
# ::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
 
127.0.0.1   localhost
192.168.73.21 openstack.cloud.priv
 
[root@openstack ~]# hostname -I
192.168.73.21 192.168.122.1
 
[root@openstack ~]# hostname
openstack.cloud.priv

1.3 关闭防火墙

[root@openstack ~]# systemctl stop firewalld
[root@openstack ~]# systemctl disable firewalld

1.4 修改SELiinux

# permissive：宽容模式：代表 SELinux 运作中，不过仅会有警告讯息并不会实际限制 domain/type 的存取。这种模式可以运来作为 SELinux 的 debug 之用

[root@openstack ~]# sed -i s#'SELINUX=enforcing'#'SELINUX=permissive'#g /etc/selinux/config
setenforce 0
getenforce    #显示为permissive就对了

1.5 安装NTP

yum -y install ntp
systemctl enable ntpd

1.6 配置cloudstack.repo

[root@openstack ~]# cat /etc/yum.repos.d/cloudstack.repo
[cloudstack]
name=cloudstack
baseurl=http://cloudstack.apt-get.eu/centos/$releasever/4.16/
enabled=1
gpgcheck=0

1.7 安装配置MySQL

1.7.1 安装MySQL

本次选择安装Mysql 5.7.39

[root@openstack ~]# wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm
[root@openstack ~]# rpm -ivh mysql-community-release-el7-7.noarch.rpm
[root@openstack ~]# yum install mysql-server -y

1.7.2 配置MySQL

# 编辑 my.cnf
[mysqld]
port=3306
default-time_zone = '+8:00'
datadir=/home/mysql_data
max_connections=500
log-error = /home/logs/mysql/error.log
general_log      = OFF
general_log_file = /home/logs/mysql/general.log
server-id=1
innodb_rollback_on_timeout=1
innodb_lock_wait_timeout=600
log_bin=mysql-bin
binlog_format=ROW
expire_logs_days=7
sql_mode="STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"
plugin-load=validate_password.so
validate-password=OFF
 
# 修改MySQL初始密码
mysql -uroot -p
SQL> ALTER USER 'root'@'%' IDENTIFIED BY 'XXXX';
SQL> flush privileges
 
# 配置 /etc/my.cnf.d/cloudstack.cnf
[root@openstack ~]# cat /etc/my.cnf.d/cloudstack.cnf
[mysqld]
 
# 重启MySQL
[root@openstack ~#] systemctl start mysql
[root@openstack ~#] systemctl enable mysql

1.7.3 安装MySQL连接器

[root@openstack ~]# yum -y install mysql-connector-python

1.8 安装配置NFS存储

1.8.1 安装NFS

yum -y install nfs-utils rpcbind

1.8.2 配置域名

# 编辑 /etc/idmapd.conf 添加
Domain = cloud.priv

1.8.3 准备NFS目录

[root@openstack ~#] mkdir -p /export/{primary,secondary}

1.8.4 修改NFS服务参数

[root@openstack ~]# cat /etc/sysconfig/nfs |grep -Ev '^$|#'
LOCKD_TCPPORT=32803
LOCKD_UDPPORT=32769
MOUNTD_PORT=892
RQUOTAD_PORT=875
STATD_PORT=662
STATD_OUTGOING_PORT=2020

1.8.5 启动查看NFS服务

[root@openstack ~#] systemctl enable rpcbind
[root@openstack ~#] systemctl enable nfs
[root@openstack ~#] systemctl start rpcbind
[root@openstack ~#] systemctl start nfs

1.8.6 配置exports文件

[root@openstack ~]# cat  /etc/exports
/export/secondary *(rw,async,no_root_squash,no_subtree_check)
/export/primary *(rw,async,no_root_squash,no_subtree_check)

1.8.7 查看共享服务

[root@openstack ~]# showmount -e openstack.cloud.priv
Export list for openstack.cloud.priv:
/export/primary   *
/export/secondary *

1.9 安装Java 11

[root@openstack ~]#  yum install java-11-openjdk -y
[root@openstack ~]# alternatives --config java
 
There is 1 program that provides 'java'.
 
  Selection    Command
-----------------------------------------------
*+ 1           java-11-openjdk.x86_64 (/usr/lib/jvm/java-11-openjdk-11.0.16.0.8-1.el7_9.x86_64/bin/java)
 
Enter to keep the current selection[+], or type selection number:

二 安装CloudStack

2.1 安装管理服务器

[root@openstack ~]#  yum -y install cloudstack-management

2.2 设置数据库

该步骤的参数设置这个让我花了一段时间思考

[root@openstack ~]#  cloudstack-setup-databases cloud:cloud@localhost --deploy-as=root:Focus*1234
Mysql user name:cloud                                                           [ OK ]

CloudStack has successfully initialized database, you can check your database configuration in /etc/cloudstack/management/db.properties

也可以查看下初始化MySQL的数据库信息，可以看到初始化了两个库 Cloud、Cloud_usage

2.3 设置管理服务器

[root@openstack ~]#  cloudstack-setup-management

2.4 系统模板设置

[root@openstack ~]#  /usr/share/cloudstack-common/scripts/storage/secondary/cloud-install-sys-tmplt -m /export/secondary -u http://download.cloudstack.org/systemvm/4.16/systemvmtemplate-4.16.1-kvm.qcow2.bz2 -h kvm -F

三、KVM安装和设置

3.1 安装KVM

[root@openstack ~]#  yum -y install epel-release
[root@openstack ~]#  yum -y install cloudstack-agent

3.2 KVM配置

配置KVM的两个不同部分：libvirt和QEMU

1. kvm负责cpu虚拟化+内存虚拟化，实现了cpu和内存的虚拟化，但kvm不能模拟其他设备
2. emu是模拟IO设备（网卡，磁盘），kvm加上qemu之后就能实现真正意义上服务器虚拟化

上面两个东西一般统称为qemu-kvm

3.2.1 QEMU配置

取消注释下面这一行

[root@openstack ~]# cat /etc/libvirt/qemu.conf |grep -Ev '^$|#'
vnc_listen = "0.0.0.0"

3.2.2 Libvirt配置

[root@openstack ~]# cat /etc/libvirt/libvirtd.conf |grep -Ev '^$|#'
listen_tls = 0
listen_tcp = 1
tcp_port = "16509"
auth_tcp = "none"
mdns_adv = 0
 
--修改/etc/sysconfig/libvirtd
[root@openstack ~]# cat /etc/sysconfig/libvirtd |grep -Ev '^$|#'
LIBVIRTD_ARGS="--listen"
 
# 重启libvirt
 
[root@openstack ~]# systemctl restart libvirtd

3.2.2 查看KVM配置

[root@openstack ~]# lsmod | grep kvm
kvm_intel             188793  0
kvm                   637515  1 kvm_intel
irqbypass              13503  1 kvm

四、登陆UI

输入用户名和密码：
