发布时间:2021-03-12 15:13:36 来源:亿速云 阅读:160 作者:Leah 栏目:系统运维

今天就跟大家聊聊有关如何在CentOS 6.3系统中部署一个CHEF环境,可能很多人都不太了解,为了让大家更加了解,小编给大家总结了以下内容,希望大家根据这篇文章可以有所收获。

安装前的准备:(chef.example.com,node1.example.com)

1.关闭iptables

代码如下:


# service iptables stop


2.关闭SELINUX

代码如下:


# setenforce 0
# vi /etc/sysconfig/selinux
---------------
SELINUX=disabled
---------------


3.同步时间(重要)

代码如下:


# ntpdate asia.pool.ntp.org
# hwclock -w


4.安装ruby环境:
详见: https://www.yisu.com/article/54981.htm

三.chef-server安装:(chef.example.com)

1.下载chef-server安装包

进入页面http://www.opscode.com/chef/install,点击Chef Server标签,选择要下载的版本
或在终端下用以下命令下载11.0.12版本:

代码如下:


# wget -c --no-check-certificate
<a href="https://opscode-omnibus-packages.s3.amazonaws.com/el/6/x86_64/chef-server-11.0.12-1.el6.x86_64.rpm">https://opscode-omnibus-packages.s3.amazonaws.com/el/6/x86_64/chef-server-11.0.12-1.el6.x86_64.rpm</a>



2.安装chef-server

终端内进入chef-server软件包所在目录,执行以下命令:

代码如下:


# rpm -ivh chef-server-11.0.12-1.el6.x86_64.rpm


注:请使用下载的软件包名称替换上面命令中的软件包名称.

3.修改本地FQDN名:

1).首先修改主机的hostname

代码如下:


# vi /etc/sysconfig/network
&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;-&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;-&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;-&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;-
HOSTNAME=chef.example.com
&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;-&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;-&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;-&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;-


2).修改本地host,添加server与node的FNDN


代码如下:


# echo "10.107.91.251 chef.example.com" >> /etc/hosts
# echo "10.107.91.252 node1.example.com" >> /etc/hosts


重启系统. 登录后验证:

代码如下:


# hostname -f
&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;-&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;-&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;-&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;-
chef.example.com
&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;-&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;-&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;-&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;-

3.配置chef-server

执行以下命令配置chef-server

代码如下:


# chef-server-ctl reconfigure


注:chef-server 10.x版本默认监听4000端口,chef-server 11.x监听443端口
SO若线上开启防火墙,需执行以下命令防火墙开启443端口

代码如下:


# iptables -I INPUT -p tcp --dport 443 -j ACCEPT
# service iptables save


现在浏览器打开https://10.107.91.251
输入:

代码如下:


username: admin
password: p@ssw0rd1


即可访问chef-server web页面.


四.chef-workstation安装:(chef.example.com)


1.安装chef-Client
进入页面http://www.opscode.com/chef/install,点击Chef Client标签,选择要下载的版本.
本例使用11.12.4-1版本:

代码如下:


# wget -c --no-check-certificate https://opscode-omnibus-packages.s3.amazonaws.com/el/6/x86_64/chef-11.12.4-1.el6.x86_64.rpm
# rpm -ivh chef-11.12.4-1.el6.x86_64.rpm



2.安装配置git

1).yum安装git:


代码如下:


# yum -y install git



2).进入root主目录,git克隆chef repository


代码如下:

# su -
# cd ~
# git clone git://github.com/opscode/chef-repo.git
&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;
Initialized empty Git repository in /root/chef-repo/.git/
remote: Reusing existing pack: 223, done.
remote: Total 223 (delta 0), reused 0 (delta 0)
Receiving objects: 100% (223/223), 45.77 KiB | 37 KiB/s, done.
Resolving deltas: 100% (57/57), done.
&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;



2.配置chef-workstation

运行命令 knife configure -i ,配置过程如下所示(只需填写chef repository一项:/root/chef-repo,其他项使用默认值):

代码如下:


# knife configure --initial
&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;
WARNING: No knife configuration file found

&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;


注: 没有出现Please enter a name for the new user: [root] 检查chef-server的443端口是否可以访问.

五.chef-workstation与chef-server不在同一服务器上的配置方法

(本例server与workstation在同一服务器,如无特殊需可略过这部分)

1.将chef-server的域名解析添加至chef-workstation的hosts文件


代码如下:


# echo "10.107.91.251 chef.example.com" >>/etc/hosts



2.在chef-workstation先创建/root/.chef目录,并将chef服务器上的/etc/chef-server/admin.pem和/etc/chef-server/chef-validator.pem文件拷贝到此目录

代码如下:


# mkdir ~/.chef
# scp chef.example.com:/etc/chef-server/admin.pem ~/.chef
# scp chef.example.com:/etc/chef-server/chef-validator.pem ~/.chef



3.执行knife configure -i命令进行初始化, 然后删除~/.chef/admin.pem

代码如下:


# knife configure --initial
# rm ~/.chef/admin.pem



4.knife configure配置过程:
1).server URL修改为chef服务器的地址https://chef.example.com:443,
2).admin's private key路径改为/root/.chef/admin.pem
3).validation key路径改为/root/.chef/chef-validation.pem
4).chef repository地址输入/root/chef-repo,其余项保持默认值.

代码如下:


# knife configure --initial
&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;
Overwrite /root/.chef/knife.rb? (Y/N) Y
Please enter the chef server URL: [https://workstation:443] https://chef.example.com:443
Please enter a name for the new user: [root]
Please enter the existing admin name: [admin]  
Please enter the location of the existing admin's private key: [/etc/chef-server/admin.pem] /root/.chef/admin.pem
Please enter the validation clientname: [chef-validator]
Please enter the location of the validation key: [/etc/chef-server/chef-validator.pem] /root/.chef/chef-validator.pem
Please enter the path to a chef repository (or leave blank): /root/chef-repo
Creating initial API user...
Please enter a password for the new user: 123456
注:这里输入API user密码(后面要使用)
Created user[root]
Configuration file written to /root/.chef/knife.rb
&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;



5.配置ruby路径(之前已安装RUBY,这里可以略过)

chef默认集成了一个ruby的稳定版本,需修改PATH变量,保证chef集成的ruby被优先使用.

代码如下:

# echo 'export PATH="/opt/chef/embedded/bin:$PATH"' >> ~/.bash_profile && source ~/.bash_profile

六.验证chef-workstation

执行knife client list命令返回client列表则配置成功.

代码如下:


# knife client list
&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;
chef-validator
chef-webui
&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;



七.chef-node配置 (node1.example.com)

node即为被chef-server配置管理的服务器

1.安装chef-Client

进入页面http://www.opscode.com/chef/install,点击Chef Client标签,选择要下载的版本.
本例使用11.12.4-1版本:

代码如下:


# wget -c --no-check-certificate https://opscode-omnibus-packages.s3.amazonaws.com/el/6/x86_64/chef-11.12.4-1.el6.x86_64.rpm
# rpm -ivh chef-11.12.4-1.el6.x86_64.rpm



2.修改本地FQDN名:

1).首先修改主机的hostname

代码如下:


# vi /etc/sysconfig/network
&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;-&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;-&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;-&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;-
HOSTNAME=node1.example.com
&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;-&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;-&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;-&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;-



2).修改本地host,添加本机和server的FNDN


代码如下:


# echo "10.107.91.251 chef.example.com" >> /etc/hosts
# echo "10.107.91.252 node1.example.com" >> /etc/hosts


重启系统. 登录后验证:

代码如下:


# hostname -f
&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;-&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;-&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;-&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;-
node1.example.com
&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;-&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;-&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;-&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;-



3.在chef-worksation执行下面命令添加并配置node


代码如下:


# knife bootstrap node1.example.com -x root -P 123456


注: 这里的密码是node1系统root账号的密码
chef-workstation通过ssh连接到node1(10.107.91.252)上执行bootstrap脚本(chef-workstation /opt/chef/embedded/lib/ruby/gems/1.9.1/gems/chef11.6.0/lib/chef/knife/bootstrap/chef-full.erb)可以使用自定义的bootstrap脚本对node进行初始化配置.
node1会下载https://www.opscode.com/chef/install.sh脚本.脚本检查操作系统类型并在网络上下载符合此系统的chef版本进行安装(下载安装较慢).可以在node上预安装chef(见workstation安装chef部分)跳过此脚本.

代码如下:


&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;-&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;-&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;-&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;-&mdash;-&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;-&mdash;-&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;-

查看是否连接node1成功:

代码如下:


# knife node list
&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;-&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;-&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;
node1
&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;-&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;-&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;


从上面可以看出node1已经成功注册到了chef-server中,整个环境 chef-workstation => chef-server => chef-client-1 已经搭建成功。

八.登陆server web后台

1.修改浏览器本机HOST,这里笔者使用的是MAC系统

代码如下:

# vi /etc/hosts
&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;-&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;-&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;
10.107.91.251 chef.example.com
10.107.91.252 node1.example.com
&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;-&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;-&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;


2.访问https://chef.example.com

九.创建一个cookbook实例

1.git克隆chef repository (chef.example.com)
注: chef repository 是一个存储cookbooks和其他文件的目录结构,初次使用需要从github克隆

代码如下:


# su -
# cd ~
# git clone git://github.com/opscode/chef-repo.git
&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;
Initialized empty Git repository in /root/chef-repo/.git/
remote: Reusing existing pack: 223, done.
remote: Total 223 (delta 0), reused 0 (delta 0)
Receiving objects: 100% (223/223), 45.77 KiB | 37 KiB/s, done.
Resolving deltas: 100% (57/57), done.
&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;


获取到的目录如下:

代码如下:


# ls
&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;
Desktop    Downloads  Pictures  Templates  anaconda-ks.cfg  install.log         src
Documents  Music      Public    Videos     chef-repo        install.log.syslog
&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;
# cd chef-repo/
# ls
&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;
LICENSE    Rakefile      chefignore  cookbooks  environments
README.md  certificates  config      data_bags  roles
&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;


2.创建一个cookbook,取名quick_start (chef.example.com)
注:需要切换到之前clone获取到的目录的cookbooks目录下

代码如下:


# cd ~/chef-repo/cookbooks
# knife cookbook create quick_start -o ./
&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;
** Creating cookbook quick_start
** Creating README for cookbook: quick_start
** Creating CHANGELOG for cookbook: quick_start
** Creating metadata for cookbook: quick_start
&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;


创建的cookbooks目录如下

代码如下:


# # ls -1p quick_start
&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;
CHANGELOG.md
README.md
attributes/
definitions/
files/
libraries/
metadata.rb
providers/
recipes/
resources/
templates/
&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;


注: cookbooks用来在chef中分布共享,大多数你创建基础实例都需要cookbooks.
此cookbook实例是创建一个简单的recipe,用来传递给node1一个简单的带有一些已经定义好的变量属性的文本.

3.创建一个属性文件,取名"quick_start.rb" (chef.example.com)

代码如下:


# vi ~/chef-repo/cookbooks/quick_start/attributes/quick_start.rb
&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;
normal[:deep_thought] = "If a tree falls in the forest ..."
&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;


注: 在cookbook中属性文件用来在node中创建一些配置,从而你可以从recipe中调用这些属性.

4.对default recipe创建一个source template源模板 (chef.example.com)

代码如下:


# vi ~/chef-repo/cookbooks/quick_start/recipes/default.rb
&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;
template "/tmp/deep_thought.txt" do
 source "deep_thought.txt.erb"
 variables :deep_thought => node[:deep_thought]
 action :create
end
&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;


注: recipes允许你对具体的源进行管理,这个例子中,你创建了一个叫quick_start的recipe,内容包括一个单独的源模板名叫template "/tmp/deep_thought.txt"

5.创建一个template模板文件 (chef.example.com)

注:这个文件调用源模板的具体属性,而后被chef传送给具体的node客户端

代码如下:

# vi ~/chef-repo/cookbooks/quick_start/templates/default/deep_thought.txt.erb
&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;
Today's deep thought: <%= @deep_thought %>
&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;


6.将cookbook上传到Server (chef.example.com)

代码如下:


# cd ~/chef-repo/cookbooks/
# ls
&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;
README.md  quick_start
&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;
# knife cookbook upload -a -o ./
&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;
Uploading quick_start  [0.1.0]
Uploaded all cookbooks.
&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;


确认你刚上传的cookbook

代码如下:


# knife cookbook list
&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;
quick_start   0.1.0
&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;


6.将quick_start recipe添加到你的node中 (chef.example.com)

代码如下:


# knife node run_list add node1.example.com 'recipe[quick_start]'
&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;
node1.example.com:
run_list: recipe[quick_start]
&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;


查看添加好的recipe

代码如下:


# knife  node show node1.example.com -r
&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;
node1.example.com:
run_list: recipe[quick_start]
&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;&mdash;


6.在node客户端注册,从而获取server上recipe的具体实例 (node1.example.com)
注:保证/etc/chef下有client.pem与validation.pem证书文件,如果没有检查之前的配置.

SSL validation of HTTPS requests is disabled. HTTPS connections are still
encrypted, but chef is not able to detect forged replies or man in the middle
attacks.
To fix this issue add an entry like this to your configuration file:
```
# Verify all HTTPS connections (recommended)
ssl_verify_mode :verify_peer
# OR, Verify only connections to chef-server
verify_api_cert true
```
To check your SSL configuration, or troubleshoot errors, you can use the
`knife ssl check` command like so:
```
knife ssl check -c /etc/chef/client.rb
```
