centos7上安装puppet
这里在docker中的两个centos容器中安装puppet。因此不存在服务器时间问题,如果是虚拟机或者物理机安装,一定要注意两台服务器时间要同步。
如果时间不同步,会导致如下错误。
Failed to generate additional resources using 'eval_generate': SSL_connect returned=1 errno=0 state=error: certificate verify failed: [CRL is not yet valid for /CN=linux-node1.com]
客户端,服务端均需要安装epel-release,默认centos yum包管理器中没有puppet相关包,需要安装扩张包即epel-release。
yum install epel-release -y
一、服务端
安装puppet-server
yum install -y puppet-server
配置hosts
172.17.0.3 91c968c989ae client.com
172.17.0.2 67783e936e27 master.com
配置puppet.conf,在[main]段增加certname属性。
[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 = $vardir/ssl
certname = master.com
编辑/etc/puppet/manifest/site.pp,指定在tmp目录创建一个文件/tmp/helloworld
node default {
file {
"/tmp/helloworld.txt":
content => "hello,world!"
}
}
启动puppetmaster
systemctl start puppetmaster
二、客户端
客户端安装puppet
yum install -y puppet
配置hosts,同服务端
配置puppet.conf,在agent段增加certname,server,report属性,如下所示:
[agent]
# The file in which puppetd stores a list of the classes
# associated with the retrieved configuratiion. Can be loaded in
# the separate ``puppet`` executable using the ``--loadclasses``
# option.
# The default value is '$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
certname = client.com
server = master.com
report = true
证书默认没有签发,测试发现,需要证书。
[root@91c968c989ae /]# puppet agent --test

三、签发证书
刚开始,客户端证书没有被审核,前面没有+
[root@67783e936e27 puppet]# puppet cert list -a
"client.com" (SHA256) C1:5A:8F:F5:65:68:EC:7B:CD:A1:9B:94:7A:B1:AB:86:0C:2C:14:0E:A5:27:5E:9C:B4:88:70:8E:D4:62:E5:81
+ "67783e936e27" (SHA256) DB:A4:97:30:A6:71:0D:16:2A:2A:C6:13:8A:CD:2E:19:97:D9:0E:5B:56:ED:59:82:AB:DF:C1:DA:BD:02:84:63
签发证书:puppet cert sign client.com,签发完成,发现证书已经被审核通过。
[root@67783e936e27 puppet]# puppet cert sign client.com
Notice: Signed certificate request for client.com
Notice: Removing file Puppet::SSL::CertificateRequest client.com at '/var/lib/puppet/ssl/ca/requests/client.com.pem'
[root@67783e936e27 puppet]# puppet cert list -a
+ "67783e936e27" (SHA256) DB:A4:97:30:A6:71:0D:16:2A:2A:C6:13:8A:CD:2E:19:97:D9:0E:5B:56:ED:59:82:AB:DF:C1:DA:BD:02:84:63
+ "client.com" (SHA256) 26:EA:AA:4F:79:4D:B6:DE:93:D7:E2:04:A0:68:83:75:0A:73:D7:D7:87:0B:48:F3:8C:7B:80:60:1F:02:F1:30
签发证书之后,再次测试,已经从服务端获取到了文件。
[root@91c968c989ae /]# puppet agent --test

[root@91c968c989ae /]#
查看客户端上的目录/tmp,有了文件helloworld.txt,并且内容为[hello,world!]
[root@91c968c989ae /]# cd /tmp
[root@91c968c989ae tmp]# cat helloworld.txt
hello,world![root@91c968c989ae tmp]#
[root@91c968c989ae tmp]# ls
helloworld.txt
[root@91c968c989ae tmp]#
