***************************************************************************************************
二、Puppet Server安装：
1.安装前的准备：
# sed -i "7s/enforcing/disabled/" /etc/selinux/config /*关闭SELinux*/
# 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
# 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：
# vi /etc/hosts
192.168.100.241 puppetserver
192.168.100.242 client01
192.168.100.243 client02
4.安装Puppet Server：
# rpm -Uvh http://yum.puppetlabs.com/el/6/products/x86_64/puppetlabs-release-6-6.noarch.rpm
# yum -y install puppet-server
# chkconfig --level 3 puppetmaster on
# service puppetmaster start
5.安装配置Mysql数据库：
# yum -y install mysql mysql-devel mysql-server
# service mysqld start
# mysqladmin -u root password 'chensh' /*设置Mysql的root密码为chensh*/
6.安装Dashboard：
# yum -y install puppet-dashboard
7.配置dashboard的database.yml文件：
# 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：
# mysql -uroot -pchensh -e 'create database dashboard character set utf8'
9.配置dashboard的environment.rb文件：
# 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：
# 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：
# vi /etc/puppet/puppet.conf
# 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 = $vardir/ssl
reports = store,http,log /*设置Dashbroad report*/
server = puppetserver
# The file in which puppetd stores a list of the classes
# associated with the retrieved configuratiion.Can be loaded in
# the separate ``puppet`` executable using the ``--loadclasses``
# option.
# The default value is '$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：
# cd /usr/share/puppet-dashboard
# rake RAILS_ENV=production db:migrate
13.启动服务：
# /etc/init.d/puppetmaster start /*puppet服务端进程，监听8140端口*/
# /etc/init.d/puppet-dashboard start /*puppet WEB，默认3000端口*/
# /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Dashboard WEB：http://192.168.100.241:3000

三、Puppet Client安装：
1.安装前的准备：
# sed -i "7s/enforcing/disabled/" /etc/selinux/config /*关闭SELinux*/
# 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 # 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：
# vi /etc/hosts
192.168.100.241 puppetserver
192.168.100.242 client01
192.168.100.243 client02
4.安装Puppet Client：
# rpm -Uvh http://yum.puppetlabs.com/el/6/products/x86_64/puppetlabs-release-6-6.noarch.rpm
# yum -y install puppet
5.指定Puppet master名称：
# echo ‘server = puppetserver’>> /etc/puppet/puppet.conf
# echo ‘reports = true’>> /etc/puppet/puppet.conf /*向服务端发送report信息*/
6.启动Puppet Client：
# chkconfig --level 3 puppet on
# 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：
# 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
#
2.服务器端查看请求签发的证书：
# 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
#
3.服务器端签发证书：
# 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'
#
4.查看已签发的证书：
# 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
#
******************************************************************************
五、证书注销：
1.注销证书：
# puppet cert revoke client01
Notice: Revoked certificate with serial 5
#
2.查看证书当前状态：
# 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)
#
3.重启puppetmaster：
# /etc/init.d/puppetmaster restart
六、证书删除：
1.删除证书：
# 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'
#
2.重启puppetmaster：
# /etc/init.d/puppetmaster restart
3.删除客户单client01.pem文件 或者 SSL目录：
# rm -rf /var/lib/puppet/ssl/certs/client01.pem /*删除client01.pem文件*/
# rm -rf /var/lib/puppet/ssl/* /*删除ssl目录下的所有文件*/
七、自动签发证书：
# 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：
#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：
# 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：
# puppet agent --test
Error: Could not request certificate: Connection timed out - connect(2)
Exiting; failed to retrieve certificate and waitforcert is disabled
#
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：
# /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：
#chmod -R 666 /usr/share/puppet-dashboard/log/production.log
