2）测试运行
为了安全我们一般使用cfagent -v –n ,带上了-n参数的意思是只是测试,而不会真的执行.

说明整个的执行过程是没问题的.粗体部分是连接服务器复制文件的过程.
上面是测试 我们现在不带-n来执行cfagent –v

可以看到已经成功的下载了cfagent.conf文件,并成功运行了
查看这个目录ls /var/cfengine/inputs 确实已经有了cfagent.conf
如果我们立刻再执行一次cfagent –v ,会发现输出有这么一句
cfengine:centos2: Nothing promised for [shellcommand./bin/echo Danger, Will Robison!] (0/1 minutes elapsed)
这句话的意思是这个配置没超过1分钟就执行过,执行的频率太快,cfengine这次是不会执行的。
如果对服务器上的配置文件做了修改,例如
|
shellcommands: "/bin/echo Danger, ======Will Robison!" 我只是在这个地方加了几个等号输出. |
然后在客户机上执行cfagent –v输出确实是多了===,不过细心的你会发现inputs目录下多了个文件
cfagent.conf.cfsaved
也就是说当cfagent成功下载了最新版本的配置文件后,会将原来的做个备份.
最后我们需要做的就是将cfengine的程序设为自动启动。客户机和服务器上
#vi /etc/rc.d/rc.local //加上下面这两行
|
/var/cfengine/bin/cfservd /var/cfengine/bin/cfenvd –H |
然后让cfagent定期执行，也就是定期到服务器上去下载最新的配置文件来执行。运行
#crontab -e
加上下面这句话
|
0,15,30,45 * * * * /var/cfengine/bin/cfexecd -F |
4．排错:
1）.原来我想的是本地子网没有域名,以为用ip就够了,就没有给出domain,在客户端运行cfagent –v输出如下
|
********************************************************************* Update Sched: copy pass 1 @ Thu Nov 1 21:52:20 2007 ********************************************************************* Checking copy from 192.168.0.114:/masterfiles/inputs to /var/cfengine/inputs Connect to 192.168.0.114 = 192.168.0.114 on port 5308 cfengine:centos2: Undefined domain name cfengine:centos2: Id-authentication for centos2.undefined.domain failed cfengine:centos2: Unable to establish connection with 192.168.0.114 (failover) Saving the setuid log in /var/cfengine/cfagent.centos2.log |
可以看到连接是失败的.因为cfservd要求连接上来的机器必须有DNS记录.
2）如果设置了domain,但是在/etc/hosts中没有连接的客户机的记录的话(也就是说只是在配置文件里面定义了域,而实际查不到dns记录)那么会有下面的错误
|
********************************************************************* Update Sched: copy pass 1 @ Thu Nov 1 22:49:42 2007 ********************************************************************* Checking copy from 192.168.0.114:/masterfiles/inputs to /var/cfengine/inputs Connect to 192.168.0.114 = 192.168.0.114 on port 5308 Loaded /var/cfengine/ppkeys/root-192.168.0.114.pub ............................................................... cfengine:centos2: Strong authentication of server=192.168.0.114 connection confirmed cfengine:centos2: Server returned error: Host authentication failed. Did you forget the domain name or IP/DNS address registration (for ipv4 or ipv6)? cfengine:centos2: Can't stat /masterfiles/inputs in copy Saving the setuid log in /var/cfengine/cfagent.centos2.log |
另外在cfservd.conf和update.conf中,服务器上用于拷贝的目录路径必须正确,否则也会报这个错误的我这里是：/masterfiles/inputs。
