server asa.kanbox.net
Client puppet.kanbox.com
案列&＃xff1a;
1    Cron计划任务测试用例    
       在site.pp中加入如下内容
       
cron{ echo: 
        command&＃61;>"echo \"This is cron job\"", 
        user&＃61;>root, 
        #hour&＃61;>[3,5], 
        minute&＃61;>&＃39;*/2&＃39;; 
    } 
    
    
2  用Client进程测试&＃xff1a;
[root&＃64;client1 ~]
# puppetd   --server  asa.kanbox.net --test  
notice: Ignoring --listen on onetime run  
info: Caching catalog for client1.centos 
info: Applying configuration version &＃39;1329980213&＃39; 
notice: /Stage[main]//Node[default]/Cron[echo]/ensure: created 
notice: Finished catalog run in 0.50 seconds 

3  检查Cron任务列表
[root&＃64;client1 ~]
# crontab -l 
# HEADER: This file was autogenerated at Thu Feb 23 14:56:53 &＃43;0800 2012 by puppet.
# HEADER: While it can still be managed manually, it is definitely not recommended.
# HEADER: Note particularly that the comments starting with &＃39;Puppet Name&＃39; should
# HEADER: not be deleted, as doing so could cause duplicate cron jobs.
# Puppet Name: echo
*/2 * * * * echo "This is cron job" 

4 配置puppet客户机同步master的cron任务。默认是半小时一次&＃xff0c;但是有时候我们需要立即生效。而不要手动执行呢&＃xff1f;所有我们需要配置客户端的同步时间
客户端设置&＃xff1a;vi /etc/puppet/puppet.conf 增加
   runinterval &＃61; 30   秒
   listen &＃61; true
vi /etc/puppet/puppet.conf
[main]
# The Puppet log directory.
# The default value is &＃39;$vardir/log&＃39;.
logdir &＃61; /var/log/puppet
# Where Puppet PID files are kept.
# The default value is &＃39;$vardir/run&＃39;.
rundir &＃61; /var/run/puppet
# Where SSL certificates are kept.
# The default value is &＃39;$confdir/ssl&＃39;.
ssldir &＃61; $vardir/ssl
[agent]
# The file in which puppetd stores a list of the classes
# associated with the retrieved configuratiion. Can be loaded in
# the separate &＃96;&＃96;puppet&＃96;&＃96; executable using the &＃96;&＃96;--loadclasses&＃96;&＃96;
# option.
# The default value is &＃39;$confdir/classes.txt&＃39;.
classfile &＃61; $vardir/classes.txt
# Where puppetd caches the local configuration. An
# extension indicating the cache format is added automatically.
# The default value is &＃39;$confdir/localconfig&＃39;.
localconfig &＃61; $vardir/localconfig
runinterval &＃61; 30
listen &＃61; true
5  修改master端/etc/sysconfig/puppet
vim /etc/sysconfig/puppet
PUPPET_SERVER&＃61;asa.kanbox.net  //改为你对应的puppetmaster的主机名  
新建namespaceauth.conf这个文件&＃xff0c;vi /etc/puppet/namespaceauth.conf添加如下内容&＃xff1a;  
[puppetrunner]  
allow *  
 
6  还需要修改auth.conf。  
在path /之前添加下内容&＃xff1a;  
path /run  
method save  
allow *  
path /  
auth any  
即可&＃xff01;  
然后重启客户端:/etc/init.d/puppet restart  
7  在服务器端测试一下&＃xff1a;执行一下命令  
新建namespaceauth.conf这个文件&＃xff0c;vi /etc/puppet/namespaceauth.conf添加如下内容&＃xff1a;  
[puppetrunner]  
allow *  
 
8  还需要修改auth.conf&＃xff08;经过检查 跟默认文件一致&＃xff09;  
在path /之前添加下内容,加粗部分&＃xff1a;  
path /run  
method save  
allow *  
path /  
auth any  
即可&＃xff01;  
9  然后重启客户端:/etc/init.d/puppet restart  
10 在服务器端测试一下&＃xff1a;执行一下命令  
puppetrun -p 10 –host puppet.kanbox.com
