安装puppet服务
在 master上安装和启用 puppet 服务:
[root@master ~]# yum install -y puppet puppet-server facter
[root@master ~]# chkconfig --list |grep puppet
puppet 0:off 1:off 2:off 3:off 4:off 5:off 6:off
puppetmaster 0:off 1:off 2:off 3:off 4:off 5:off 6:off
[root@master ~]# chkconfig puppet on
[root@master ~]# service puppetmaster start
Starting puppetmaster: [ OK ]
[root@master ~]#vi /etc/sysconfig/network
hostname master.test.com
在clients上安装puppet客户端
[root@node1 ~]# yum install -y puppet
[root@node1 ~]# chkconfig --list |grep puppet
puppet 0:off 1:off 2:off 3:off 4:off 5:off 6:off
[root@node1 ~]# chkconfig puppet on
[root@node1 ~]# chkconfig --list |grep puppet
puppet 0:off 1:off 2:on 3:on 4:on 5:on 6:off
[root@node1 ~]# service puppet start
Starting puppet agent: [ OK ]
[root@node1 ~]#
在clients上解析pupetmaster 的域名
[root@node1 ~]#vim /etc/hosts
192.168.50.30 master.test.com
3.配置puppet
对于puppet 客户端,修改/etc/puppet/puppet.conf,指定master服务器
[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 = $vardir/ssl
[agent]
# The file in which puppetd stores a list of the classes
# associated with the retrieved configuratiion. Can be loaded in# the separate ``puppet`` executable using the ``--loadclasses``
# option.
# The default value is '$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
server = master.test.com
并重启puppet服务
[root@node1 ~]# service puppet restart
Stopping puppet agent: [ OK ]
Starting puppet agent: [ OK ]
[root@node1 ~]#
4.Client申请证书
服务端自动签发证书设置
设置master自动签发所有的证书,我们只需要在/etc/puppet 目录下创建 autosign.conf 文件。(不需要修改 /etc/puppet/puppet.conf文件,因为我默认的autosign.conf 文件的位置没有修改)
[root@master ~]# ll /etc/puppet/
total 28
-rw-r--r--. 1 root root 4178 Nov 4 06:24 auth.conf
drwxr-xr-x. 3 root root 4096 Dec 29 15:44 environments
-rw-r--r--. 1 root root 1462 Nov 4 06:23 fileserver.conf
drwxr-xr-x. 2 root root 4096 Nov 4 06:24 manifests
drwxr-xr-x. 2 root root 4096 Nov 4 06:24 modules
-rw-r--r--. 1 root root 853 Nov 4 06:23 puppet.conf
[root@master ~]# cat > /etc/puppet/autosign.conf <<EOF
> *.fisteam2.com
> EOF
[root@master ~]# service puppetmaster restart
Stopping puppetmaster: [ OK ]
Starting puppetmaster: [ OK ]
[root@master ~]#
这样就会对所有来自fisteam2.com的机器的请求,都自动签名。
client需要向服务器端发出请求, 让服务器对客户端进行管理. 这其实是一个证书签发的过程. 第一次运行puppet 客户端的时候会生成一个 SSL 证书并指定发给 Puppet 服务端, 服务器端如果同意管理客户端,就会对这个证书进行签发,可以用这个命令来签发证书,由于我们已经在客户端设置了server地址,因此不需要跟服务端地址
[root@master ~]# puppet agent
为了详细了解注册的过程和日后排错,可以增加参数,因为配置文件里
–no-daemonize 前台输出日志
–verbose 输入更加详细的日志
–debug 更加详细的日志,排错的时候使用
–test 表示测试,就带一个–test参数就可以
[root@node1 ~]# puppet agent --no-daemonize --onetime --verbose --debug
就可以申请证书了,由于我配置的自动签发证书,所以直接就签发了,在服务端执行
[root@master ~]# puppet cert list --all
就可以看到所有客户端已经都已签发证书,前面带”+”号的就是签发成功的,如果没有签名的,可以用
[root@master ~]# puppet cert --sign node1.localdomain
即可看到证书已经签发。
