注意：本教程的方法建立在基于KVM构架的VPS或独立服务器上。
前提准备：VPS或服务器安装CentOS 6及以上系统。update系统，并安装vim编辑器。
1、关闭selinux并配置iptables（重要）
vim /etc/sysconfig/selinux
添加内容：
SELINUX=disabled
保存。
开放iptables的3000端口：
/sbin/iptables -I INPUT -p tcp --dport 3000 -j ACCEPT
/etc/rc.d/init.d/iptables save
/etc/init.d/iptables restart
2、安装OpenVZ
配置YUM源
cd /etc/yum.repos.d
wget http://download.openvz.org/openvz.repo
rpm --import http://download.openvz.org/RPM-GPG-Key-OpenVZ
yum update -y
安装OpenVZ内核和vzctl、vzquota等工具
yum install vzkernel
yum install vzctl vzquota
配置OS内核参数，进入/etc/sysctl.conf文件，修改下面两个参数
为了让VE访问外部网络，需要对IP进行转发
net.ipv4.ip_forward = 1
主要是控制对kernel系统信息的debug功能
kernel.sysrq = 1
使上面的配置文件生效
modprobe bridge
lsmod|grep bridge
现在reboot，重启后检查VZ服务是否运行
chkconfig --list vz
返回如下信息则代表正在运行
vz 0:off 1:off 2:on 3:on 4:on 5:on 6:off
启动之前可以先检查一下OpenVZ服务时候已经启动了
service vz status
service vz start
3、安装OpenVZ Web Panel
wget -O - https://raw.githubusercontent.com/sibprogrammer/owp/master/installer/ai.sh | sh
安装结束后，使用如下信息登录控制面板
http://:3000
4、添加hw-daemon.rb内容
vim /opt/ovz-web-panel/utils/hw-daemon/hw-daemon.rb
添加如下内容：
#!/usr/bin/env ruby
require 'webrick'
require 'xmlrpc/server.rb'
# workaround for clients with incorrect DNS records
Socket.do_not_reverse_lookup = true
ENV['PATH'] += ':/usr/sbin'
DAEMON_VERSION = '1.3'
CURRENT_DIR = File.expand_path(File.dirname(__FILE__)) + '/'
CONFIG_FILE = CURRENT_DIR + 'hw-daemon.ini'
PID_FILE = CURRENT_DIR + 'hw-daemon.pid'
LOG_FILE = CURRENT_DIR + 'hw-daemon.log'
SSL_CERT_FILE = CURRENT_DIR + "/certs/server.crt"
SSL_PKEY_FILE = CURRENT_DIR + "/certs/server.key"
$SERVER_ADDRESS = "0.0.0.0"
$SERVER_PORT = 7767
$AUTH_KEY = ""
$DEBUG = false
$LOG = WEBrick::Log.new(LOG_FILE)
$SSL_ENABLE = false
$SSL_CERT = ''
$SSL_PKEY = ''
$THREADS = {}
class HwDaemonApiHandler < XMLRPC::WEBrickServlet
def version
DAEMON_VERSION
end
def exec(command, args = '')
output = `#{command} #{args} 2>&1`
exit_code = $?
$LOG.debug("Exec command: #{command} #{args}; code: #{exit_code}; output:\n#{output}")
{ 'exit_code' => exit_code >> 8, 'output' => output }
end
def job(command, args = '')
job_id = generate_id
t = Thread.new do
result = self.exec(command, args)
$THREADS[job_id]['result'] = result
end
$THREADS[job_id] = { 'thread' => t }
{ 'job_id' => job_id }
end
def job_status(job_id)
found = $THREADS.has_key?(job_id)
result = ''
if found
alive = $THREADS[job_id]['thread'].alive?
result = $THREADS[job_id]['result'] unless alive
end
{ 'found' => found, 'alive' => alive, 'result' => result }
end
def write_file(filename, content)
File.open(filename, 'w') { |file| file.write(content) }
$LOG.debug("Writing file: #{filename}")
end
def service(request, response)
WEBrick::HTTPAuth.basic_auth(request, response, '') do |user, password|
user == 'admin' && password == $AUTH_KEY
end
super
end
def handle(method, *params)
$LOG.debug("Execute method: #{method}")
