***************************************************************************************************

二、Puppet Server安装：

1.安装前的准备：

[root@puppetserver ~]# sed -i "7s/enforcing/disabled/" /etc/selinux/config /*关闭SELinux*/

[root@puppetserver ~]# vi /etc/sysconfig/iptables /*编辑防火墙打开8140和3000端口*/

-A INPUT -m state --state NEW -p tcp --dport 8140 -j ACCEPT

-A INPUT -m state --state NEW -p tcp --dport 3000 -j ACCEPT

[root@puppetserver ~]# reboot

2.配置NTP服务：

请参考：《CentOS 6.3下NTP服务安装和配置》

3.配置hosts文件：

[root@puppetserver ~]# vi /etc/hosts

192.168.100.241 puppetserver

192.168.100.242 client01

192.168.100.243 client02

4.安装Puppet Server：

[root@puppetserver ~]# rpm -Uvh http://yum.puppetlabs.com/el/6/products/x86_64/puppetlabs-release-6-6.noarch.rpm
[root@puppetserver ~]# yum -y install puppet-server

[root@puppetserver ~]# chkconfig --level 3 puppetmaster on

[root@puppetserver ~]# service puppetmaster start

5.安装配置Mysql数据库：

[root@puppetserver ~]# yum -y install mysql mysql-devel mysql-server

[root@puppetserver ~]# service mysqld start

[root@puppetserver ~]# mysqladmin -u root password 'chensh' /*设置Mysql的root密码为chensh*/

6.安装Dashboard：

[root@puppetserver ~]# yum -y install puppet-dashboard

7.配置dashboard的database.yml文件：

[root@puppetserver ~]# vi /usr/share/puppet-dashboard/config/database.yml

修改部分内容如下：

production:

database: dashboard

username: root
password: chensh
encoding: utf8
adapter: mysql

8.创建dashboard数据库，数据库名为dashboard：

[root@puppetserver ~]# mysql -uroot -pchensh -e 'create database dashboard character set utf8'

9.配置dashboard的environment.rb文件：

[root@puppetserver ~]# vi /usr/share/puppet-dashboard/config/environment.rb

将config.time_zone = 'UTC'改为config.time_zone = 'Beijing'

10.修改/etc/sysconfig/puppet文件：

[root@puppetserver ~]# vi /etc/sysconfig/puppet

# The puppetmaster server PUPPET_SERVER=puppetserver

# If you wish to specify the port to connect to do so here

PUPPET_PORT=8140

# Where to log to. Specify syslog to send log messages to the system log.

PUPPET_LOG=/var/log/puppet/puppet.log

# You may specify other parameters to the puppet client here

# PUPPET_EXTRA_OPTS=--waitforcert=500

11.修改/etc/puppet/puppet.conf文件：

[root@puppetserver ~]# vi /etc/puppet/puppet.conf

[main]

# The Puppet log directory.

# The default value is '$vardir/log'.

logdir = /var/log/puppet

# Where Puppet PID files are kept.

# The default value is '$vardir/run'.

rundir = /var/run/puppet

# Where SSL certificates are kept.

# The default value is '$confdir/ssl'.

ssldir = $vardir/ssl

reports = store,http,log /*设置Dashbroad report*/

server = puppetserver

[agent]

# The file in which puppetd stores a list of the classes

# associated with the retrieved configuratiion. Can be loaded in

# the separate ``puppet`` executable using the ``--loadclasses``

# option.

# The default value is '$confdir/classes.txt'.

classfile = $vardir/classes.txt

# Where puppetd caches the local configuration. An

# extension indicating the cache format is added automatically.

# The default value is '$confdir/localconfig'.

localconfig = $vardir/localconfig

runinterval = 3600 /*设置检测时间间隔3600s*/

12.初始化Dashboard数据库：

[root@puppetserver ~]# cd /usr/share/puppet-dashboard

[root@puppetserver puppet-dashboard]# rake RAILS_ENV=production db:migrate

13.启动服务：

[root@puppetserver ~]# /etc/init.d/puppetmaster start /*puppet服务端进程，监听8140端口*/

[root@puppetserver ~]# /etc/init.d/puppet-dashboard start /*puppet WEB，默认3000端口*/

[root@puppetserver ~]# /etc/init.d/puppet-dashboard-workers start /*新版本新增的进程，不启动dashboard上面看不到数据*/

14.访问[b]Dashboard WEB：http://192.168.100.241:3000[/b]



三、Puppet Client安装：

1.安装前的准备：

[root@client01 ~]# sed -i "7s/enforcing/disabled/" /etc/selinux/config /*关闭SELinux*/

[root@client01 ~]# vi /etc/sysconfig/iptables /*编辑防火墙打开8140端口*/

-A INPUT -m state --state NEW -p tcp --dport 8140 -j ACCEPT[root@client01 ~]# reboot

2.配置NTP客户端服务：

请参考：《CentOS 6.3下NTP服务安装和配置》

3.配置hosts文件：

[root@client01 ~]# vi /etc/hosts

192.168.100.241 puppetserver

192.168.100.242 client01

192.168.100.243 client02

4.安装Puppet Client：

[root@client01 ~]# rpm -Uvh http://yum.puppetlabs.com/el/6/products/x86_64/puppetlabs-release-6-6.noarch.rpm
[root@client01 ~]# yum -y install puppet

5.指定Puppet master名称：

[root@client01 ~]# echo ‘server = puppetserver’ >> /etc/puppet/puppet.conf

[root@client01 ~]# echo ‘reports = true’ >> /etc/puppet/puppet.conf /*向服务端发送report信息*/

6.启动Puppet Client：

[root@client01 ~]# chkconfig --level 3 puppet on

[root@client01 ~]# service puppet start

四、客户端证书申请与服务端认证：

1.客户端证书申请：

[root@client01 ~]# puppet agent --test --server puppetserver /*执行 puppet agent --test也可以*/

Info: Creating a new SSL key for client01

Info: Caching certificate for ca

Info: Creating a new SSL certificate request for client01

Info: Certificate Request fingerprint (SHA256): 69:45:4C:45:17:A9:7C:6F:24:04:8F:0B:F7:44:4D:4D:59:BA:4F:9D:71:35:04:3F:8F:29:0E:63:50:55:16:F3

Exiting; no certificate found and waitforcert is disabled

[root@client01 ~]#

2.服务器端查看请求签发的证书：

[root@puppetserver ~]# puppet cert --list

"client01" (SHA256) 69:45:4C:45:17:A9:7C:6F:24:04:8F:0B:F7:44:4D:4D:59:BA:4F:9D:71:35:04:3F:8F:29:0E:63:50:55:16:F3

[root@puppetserver ~]#

3.服务器端签发证书：

[root@puppetserver ~]# puppet cert --sign client01 /*多证书可执行puppet cert --sign --all批量签发*/

Notice: Signed certificate request for client01

Notice: Removing file Puppet::SSL::CertificateRequest client01 at '/var/lib/puppet/ssl/ca/requests/client01.pem'

[root@puppetserver ~]#

4.查看已签发的证书：

[root@puppetserver~]# puppet cert --list --all

+ "client01" (SHA256) 37:5D:E3:E4:09:07:BA:41:16:D5:16:0A:B0:1F:67:5A:20:BB:65:CB:21:EE:A6:C3:30:DB:C6:77:01:9F:EF:18

[root@puppetserver~]#

******************************************************************************

五、证书注销：

1.注销证书：

[root@puppetserver~]# puppet cert revoke client01

Notice: Revoked certificate with serial 5

[root@puppetserver~]#

2.查看证书当前状态：

[root@puppetserver~]# puppet cert list --all

- "client01" (SHA256) 37:5D:E3:E4:09:07:BA:41:16:D5:16:0A:B0:1F:67:5A:20:BB:65:CB:21:EE:A6:C3:30:DB:C6:77:01:9F:EF:18 (certificate revoked)

[root@puppetserver~]#

3.重启puppetmaster：

[root@puppetserver ~]# /etc/init.d/puppetmaster restart

六、证书删除：

1.删除证书：

[root@puppetserver~]# puppet cert clean client01

Notice: Revoked certificate with serial 5

Notice: Removing file Puppet::SSL::Certificate client01 at '/var/lib/puppet/ssl/ca/signed/client01.pem'

Notice: Removing file Puppet::SSL::Certificate client01 at '/var/lib/puppet/ssl/certs/client01.pem'

[root@puppetserver~]#

2.重启puppetmaster：

[root@puppetserver ~]# /etc/init.d/puppetmaster restart

3.删除客户单client01.pem文件 或者 SSL目录：

[root@client01 ~]# rm -rf /var/lib/puppet/ssl/certs/client01.pem /*删除client01.pem文件*/

[root@client01 ~]# rm -rf /var/lib/puppet/ssl/* /*删除ssl目录下的所有文件*/

七、自动签发证书：

[root@puppetserver ~]# echo “*” >> /etc/puppet/autosign.conf

******************************************************************************

问题总结：

问题1：

执行数据库初始化时报错如下：

[root@puppetmaster puppet-dashboard]# rake RAILS_ENV=production db:migrate

rake aborted!

syntax error on line 49, col 2: ` encoding: utf8'

(See full trace by running task with --trace)

解决办法：

[root@puppetmaster puppet-dashboard]# vi /usr/share/puppet-dashboard/config/database.yml

production:

database: dashboard

username: root
password:chensh
encoding: utf8
adapter: mysql

将"password:chensh"改为"password: chensh"(即加一个“空格”符)，再次执行"rake RAILS_ENV=production db:migrate"即可。

问题2：

[root@client01 ~]# puppet agent --test

Error: Could not request certificate: Connection timed out - connect(2)

Exiting; failed to retrieve certificate and waitforcert is disabled

[root@client01 ~]#

解决办法：

请查看网络、SElinux、iptables以及hosts文件中的IP和主机名是否配置正确。

问题3：

[root@puppetserver puppet]# /etc/init.d/puppet-dashboard-workers restart

Rails Error: Unable to access log file. Please ensure that /usr/share/puppet-dashboard/log/production.log exists and is chmod 0666. The log level has been raised to WARN and the output directed to STDERR until the problem is fixed.

解决办法：

[root@puppetserver puppet]# chmod -R 666 /usr/share/puppet-dashboard/log/production.log
