客户端安装的第二种方法：

[root@chef-server ~]# curl https://www.opscode.com/chef/install.sh ｜ bash

本文安装参考：http://blog.sina.com.cn/s/blog_b20664f801018yox.html

1 确保hostname是FQDN格式:

[root@chef-server ~]# more /etc/sysconfig/network

NETWORKING=yes

HOSTNAME=chef-server.tian.com

[root@chef-server ~]# more /etc/hosts

127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4

::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

127.0.0.1 chef-server.tian.com chef-server

[root@chef-server ~]# hostname -f

chef-server.tian.com

[root@chef-server ~]#

1.chef server在centos6.x系统上安装

[root@chef-server ~]# rpm -Uvh http://rbel.frameos.org/rbel6

[root@chef-server ~]# yum install rubygem-chef-server

[root@chef-server ~]# chkconfig iptables off

[root@chef-server ~]# service iptables stop
[root@chef-server ~]# /usr/sbin/setup-chef-server.sh

Checking RabbitMQ...

RabbitMQ not running. Starting...

Starting rabbitmq-server: SUCCESS

rabbitmq-server.

Configuring RabbitMQ default Chef user...

Starting CouchDB...

Starting couchdb: [ OK ]

Enabling Chef Services...

Starting Chef Services...

Starting chef-server: [ OK ]

Starting chef-server-webui: [ OK ]

Starting chef-solr: [ OK ]

Starting chef-expander: [ OK ]

[root@chef-server ~]# /usr/sbin/setup-chef-server.sh 如果提示

Checking RabbitMQ...

RabbitMQ not running. Starting...

Starting rabbitmq-server: FAILED - check /var/log/rabbitmq/startup_{log, _err}

rabbitmq-server.

Cannot start rabbitmq-server. Aborting.

以上错误，需要修改rabbitmq.conf文件，如下：vi /etc/rabbitmq/rabbitmq.conf

NODENAME=rabbitmq@localhost

NODE_IP_ADDRESS=127.0.0.1

同时保证hostname的输入与/etc/hosts内容一致

[root@chef-server ~]# netstat -tlnp | grep chef

tcp 0 0 0.0.0.0:4040 0.0.0.0:* LISTEN 2295/merb :ch ef-se

tcp 0 0 0.0.0.0:4000 0.0.0.0:* LISTEN 2251/merb : chef-se

[root@chef-server ~]#

2.配置一个管理chef的客户端

以下一路回车即可
[root@chef-server ~]# knife configure -i

WARNING: No knife configuration file found

Where should I put the config file? [~/.chef/knife.rb]

Please enter the chef server URL: [http://chef-server.tian.com:4000]

Please enter a clientname for the new client: [root]

Please enter the existing admin clientname: [chef-webui]

Please enter the location of the existing admin client's private key: [/etc/chef/webui.pem]

Please enter the validation clientname: [chef-validator]

Please enter the location of the validation key: [/etc/chef/validation.pem]

Please enter the path to a chef repository (or leave blank):

Creating initial API user...

Created client[root]

Configuration file written to /root/.chef/knife.rb

[root@chef-server ~]#

3.验证chef server是否安装完成正常使用

[root@chef-server ~]# chef-client

[root@chef-server ~]#

4.chef 客户端安装

1) centos5.x 安装
[root@chef-client ~]# yum install wget

wget -O /etc/yum.repos.d/aegisco.repo http://rpm.aegisco.com/aegisco/el5/aegisco.repo

[root@chef-client ~]# rpm -Uvh http://rbel.frameos.org/rbel5

[root@chef-client ~]# yum install ruby ruby-devel ruby-ri ruby-rdoc ruby-shadow gcc gcc-c++ automake autoconf make curl dmidecode

2) centos6.x 安装

[root@chef-client ~]# rpm -Uvh http://rbel.frameos.org/rbel6

[root@chef-client ~]# yum install -y ruby ruby-devel ruby-ri ruby-rdoc ruby-shadow gcc gcc-c++ automake autoconf make curl dmidecode

3) 以上 1)和2）安装好后进行如下

[root@chef-client ~]# cd /tmp ; curl -O http://production.cf.rubygems.org/rubygems/rubygems-1.8.10.tgz

[root@chef-client tmp]# tar zxf rubygems-1.8.10.tgz ; cd rubygems-1.8.10

[root@chef-client rubygems-1.8.10]# ruby setup.rb --no-format-executable

[root@chef-client rubygems-1.8.10]# gem install chef --no-ri --no-rdoc
