CentOS6.5+Puppet3.7.3 安装、配置及测试
OS:CentOS-6.5-x86_64
Puppet 3.7.3
Puppet master: master.fisteam2.com
Puppet clients:node1-5.fisteam2.com
Puppet 要求所有机器有完整的域名（FQDN），如果没有 DNS 服务器提供域名的话，可以在两台机器上设置主机名（注意要先设置主机名再安装 Puppet，因为安装 Puppet 时会把主机名写入证书，客户端和服务端通信需要这个证书）,因为我配置了DNS，所以就不用改hosts了，如果没有就需要改hosts文件指定。
1.关闭selinux，iptables，并设置ntp
采用CentOS-6.5-x86_64.iso进行minimal最小化安装
关闭selinux
[root@master ~]# cat /etc/selinux/config
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=enforcing
# SELINUXTYPE= can take one of these two values:
# targeted - Targeted processes are protected,
# mls - Multi Level Security protection.
SELINUXTYPE=targeted
[root@master ~]# sed -i '/SELINUX/ s/enforcing/disabled/g' /etc/selinux/config
[root@master ~]# cat /etc/selinux/config
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of these two values:
# targeted - Targeted processes are protected,
# mls - Multi Level Security protection.
SELINUXTYPE=targeted
[root@master ~]# setenforce 0
停止iptables
[root@node1 ~]# chkconfig --list |grep tables
ip6tables 0:off 1:off 2:on 3:on 4:on 5:on 6:off
iptables 0:off 1:off 2:on 3:on 4:on 5:on 6:off
[root@node1 ~]# chkconfig ip6tables off
[root@node1 ~]# chkconfig iptables off
[root@node1 ~]# service ip6tables stop
ip6tables: Setting chains to policy ACCEPT: filter [ OK ]
ip6tables: Flushing firewall rules: [ OK ]
ip6tables: Unloading modules: [ OK ]
[root@node1 ~]# service iptables stop
iptables: Setting chains to policy ACCEPT: filter [ OK ]
iptables: Flushing firewall rules: [ OK ]
iptables: Unloading modules: [ OK ]
[root@node1 ~]#
设置ntp
[root@master ~]# ntpdate pool.ntp.org
[root@master ~]# chkconfig --list|grep ntp
ntpd 0:off 1:off 2:off 3:off 4:off 5:off 6:off
ntpdate 0:off 1:off 2:off 3:off 4:off 5:off 6:off
[root@master ~]# chkconfig ntpd on
[root@master ~]# service ntpd start
Starting ntpd: [ OK ]
[root@master ~]#
2.安装puppet服务
puppet不在CentOS的基本源中，需要加入 PuppetLabs 提供的官方源：
[root@master ~]# wget http://yum.puppetlabs.com/el/6/products/x86_64/puppetlabs-release-6-7.noarch.rpm
[root@master ~]# rpm -ivh puppetlabs-release-6-7.noarch.rpm
[root@master ~]#yum update
在 master上安装和启用 puppet 服务：
[root@master ~]# yum install puppet-server
[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 ~]#
在clients上安装puppet客户端
[root@node1 ~]# yum install 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 ~]#
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.fisteam2.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。
