搭建私人云服务器所需条件

1、服务器硬件：一台性能稳定的物理服务器，推荐配置为Intel Xeon处理器、16GB内存、1TB硬盘等。

2、操作系统：CentOS、Ubuntu等主流Linux操作系统。

3、网络环境：公网IP地址、足够的带宽。

4、云存储软件：如OpenStack、Ceph等。

5、网络工具：如Nginx、Keepalived等。

搭建步骤

1、服务器硬件安装

（1）根据服务器硬件配置，安装相应的操作系统。

（2）配置网络，确保服务器可以访问互联网。

2、安装云存储软件

以OpenStack为例，以下是安装步骤：

（1）安装OpenStack环境依赖包：

yum install -y python-openstackclient python-pip openstack-selinux

（2）安装OpenStack组件：

yum install -y openstack-dashboard openstack-nova-api openstack-nova-conductor openstack-nova-novncproxy openstack-neutron openstack-neutron-ml2 openstack-neutron-linuxbridge ebtables ipset

（3）初始化OpenStack环境：

openstack admin-stack.sh

（4）配置OpenStack组件：

- nova.conf：

[DEFAULT]
verbose = True
transport_url = rabbit://openstack:openstack@controller
my_ip = 192.168.1.100
auth_strategy = keystone
log_dir = /var/log/openstack
log_file = nova.log
[api]
host = controller
port = 8774
[database]
connection = mysql://openstack:openstack@controller/nova
[glance]
api_servers = controller:9292
[keystone_authtoken]
auth_uri = http://controller:5000
auth_url = http://controller:35357
memcached_servers = controller:11211
auth_type = password
project_domain_name = Default
user_domain_name = Default
project_name = service
username = nova
password = nova
[oslo_concurrency]
lock_path = /var/lib/nova/tmp
[nova]
vncserver_listen = 0.0.0.0
vncserver_proxyclient_address = controller
novncproxy_base_url = http://controller:6080/vnc_auto.html
session_timeout = 60
rootwrap_config = /etc/nova/rootwrap.conf
firewall_driver = nova.virt.firewall.NoopFirewallDriver
libvirt_python = libvirt-python

- neutron.conf：

[DEFAULT]
verbose = True
transport_url = rabbit://openstack:openstack@controller
auth_strategy = keystone
log_dir = /var/log/openstack
log_file = neutron.log
[keystone_authtoken]
auth_uri = http://controller:5000
auth_url = http://controller:35357
memcached_servers = controller:11211
auth_type = password
project_domain_name = Default
user_domain_name = Default
project_name = service
username = neutron
password = neutron
[database]
connection = mysql://openstack:openstack@controller/neutron
[service]
host = controller

- neutron-linuxbridge-agent.conf：

[DEFAULT]
verbose = True
agent_config_file = /etc/neutron/plugins/ml2/linuxbridge_agent.ini
[linuxbridge_agent]
tenant_network_types = flat,vlan
physical_interface_mappings = eth0:physnet1

（5）启动OpenStack组件：

systemctl start openstack-nova-api openstack-nova-conductor openstack-nova-novncproxy openstack-neutron-linuxbridge neutron-openvswitch-agent openstack-neutron-agent-linuxbridge

（6）配置防火墙和SELinux：

firewall-cmd --permanent --add-port=8774/tcp
firewall-cmd --permanent --add-port=35357/tcp
firewall-cmd --permanent --add-port=6080/tcp
firewall-cmd --reload
setsebool -P openstack_novaBrother=1
setsebool -P openstack_novaCompute=1
setsebool -P openstack_novaDeployer=1
setsebool -P openstack_novaNetwork=1
setsebool -P openstack_novaRamdisk=1
setsebool -P openstack_novaScheduler=1
setsebool -P openstack_novaVirtDriver=1

3、安装网络工具

以Nginx为例，以下是安装步骤：

yum install -y nginx

配置Nginx反向代理：

server {
    listen 80;
    server_name controller;
    location /vnc_auto.html {
        proxy_pass http://controller:6080/vnc_auto.html;
    }
    location /novncproxy {
        proxy_pass http://controller:6080/novncproxy;
    }
}

4、配置Keepalived实现高可用

以Keepalived为例，以下是配置步骤：

（1）在两台控制器服务器上分别安装Keepalived：

yum install -y keepalived

（2）配置Keepalived：

- controller1：

! Configuration File for keepalived
global_defs {
   router_id controller1
}
vrrp_instance VI_1 {
   state MASTER
   interface eth0
   virtual_ipaddress {
       192.168.1.100/24 dev eth0 label eth0:0
   }
   priority 100
   advert_int 1
   autoshutdown enable
   autoshutdown_delay 5
   track_interface eth0
   virtual_router_id 51
}
virtual_server 192.168.1.100 8774 {
   lbmethod roundrobin
   persistence_timeout 50
   protocol http
   real_server 192.168.1.101 8774 {
       weight 1
       SSL Protestant
       server_name controller
       on_failure_down_mark 30
       on_failure_max 5
   }
   real_server 192.168.1.102 8774 {
       weight 1
       SSL Protestant
       server_name controller
       on_failure_down_mark 30
       on_failure_max 5
   }
}

- controller2：

! Configuration File for keepalived
global_defs {
   router_id controller2
}
vrrp_instance VI_1 {
   state BACKUP
   interface eth0
   virtual_ipaddress {
       192.168.1.100/24 dev eth0 label eth0:0
   }
   priority 90
   advert_int 1
   autoshutdown enable
   autoshutdown_delay 5
   track_interface eth0
   virtual_router_id 51
}
virtual_server 192.168.1.100 8774 {
   lbmethod roundrobin
   persistence_timeout 50
   protocol http
   real_server 192.168.1.101 8774 {
       weight 1
       SSL Protestant
       server_name controller
       on_failure_down_mark 30
       on_failure_max 5
   }
   real_server 192.168.1.102 8774 {
       weight 1
       SSL Protestant
       server_name controller
       on_failure_down_mark 30
       on_failure_max 5
   }
}

（3）启动Keepalived：

systemctl start keepalived
systemctl enable keepalived
