CentOS6.5+puppet3.7.3 安装、配置及测试

y45t4r3

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

[iyunv@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

[iyunv@master ~]# sed -i '/SELINUX/ s/enforcing/disabled/g' /etc/selinux/config

[iyunv@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

[iyunv@master ~]# setenforce 0

停止iptables

[iyunv@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

[iyunv@node1 ~]# chkconfig ip6tables off

[iyunv@node1 ~]# chkconfig iptables off

[iyunv@node1 ~]# service ip6tables stop

ip6tables: Setting chains to policy ACCEPT: filter [ OK ]

ip6tables: Flushing firewall rules: [ OK ]

ip6tables: Unloading modules: [ OK ]

[iyunv@node1 ~]# service iptables stop

iptables: Setting chains to policy ACCEPT: filter [ OK ]

iptables: Flushing firewall rules: [ OK ]

iptables: Unloading modules: [ OK ]

[iyunv@node1 ~]#

设置ntp

[iyunv@master ~]# ntpdate pool.ntp.org

[iyunv@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

[iyunv@master ~]# chkconfig ntpd on

[iyunv@master ~]# service ntpd start

Starting ntpd: [ OK ]

[iyunv@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：

[iyunv@master ~]# wget http://yum.puppetlabs.com/el/6/p ... ease-6-7.noarch.rpm

[iyunv@master ~]# rpm -ivh puppetlabs-release-6-7.noarch.rpm

[iyunv@master ~]#yum update

在 master上安装和启用 puppet 服务：

[iyunv@master ~]# yum install puppet-server

[iyunv@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

[iyunv@master ~]# chkconfig puppet on

[iyunv@master ~]# service puppetmaster start

Starting puppetmaster: [ OK ]

[iyunv@master ~]#


在clients上安装puppet客户端

[iyunv@node1 ~]# yum install puppet

[iyunv@node1 ~]# chkconfig --list |grep puppet

puppet 0:off 1:off 2:off 3:off 4:off 5:off 6:off

[iyunv@node1 ~]# chkconfig puppet on

[iyunv@node1 ~]# chkconfig --list |grep puppet

puppet 0:off 1:off 2:on 3:on 4:on 5:on 6:off

[iyunv@node1 ~]# service puppet start

Starting puppet agent: [ OK ]

[iyunv@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

[iyunv@node1 ~]# service puppet restart

Stopping puppet agent: [ OK ]

Starting puppet agent: [ OK ]

[iyunv@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）

[iyunv@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

[iyunv@master ~]# cat > /etc/puppet/autosign.conf <<eof

> *.fisteam2.com

> EOF

[iyunv@master ~]# service puppetmaster restart

Stopping puppetmaster: [ OK ]

Starting puppetmaster: [ OK ]

[iyunv@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

[iyunv@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

[iyunv@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

[iyunv@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

[iyunv@master ~]# puppet cert --sign node1.localdomain

即可看到证书已经签发  
5.在服务端安装puppet的dashboard  
安装mysql

[iyunv@master ~]# yum install -y mysql mysql-devel mysql-server

优化mysql设置

编辑 /etc/my.cnf, 在[mysqld]字段,增加最后一行

[iyunv@master ~]# vim /etc/my.cnf

启动Mysql服务

[iyunv@master ~]# service mysqld start[iyunv@master ~]# chkconfig mysqld on [iyunv@master ~]# chkconfig --list |grep mysqld mysqld 0:off 1:off 2:on 3:on 4:on 5:on 6:off

设置mysql密码，我这里使用是密码是123456

[iyunv@master ~]# mysqladmin -u root password '123456'

创建一个dashboard数据库

[iyunv@master ~]# mysql -uroot -p123456 < CREATE DATABASE dashboard CHARACTER SET utf8;> CREATE USER 'dashboard'@'localhost' IDENTIFIED BY '123456';> GRANT ALL PRIVILEGES ON dashboard.* TO 'dashboard'@'localhost';> FLUSH PRIVILEGES;> EOF[iyunv@master ~]#

Passenger+Apache+Dashboard

这是让Apache支持ruby,由于Passenger不在centos官方源里，因此要添加epel的源

[iyunv@master ~]# wget http://dl.fedoraproject.org/pub/ ... ease-6-8.noarch.rpm [iyunv@master ~]# rpm -ivh epel-release-6-8.noarch.rpm [iyunv@master ~]# yum install mod_passenger puppet-dashboard

配置Dashboard

[iyunv@master ~]# vim /usr/share/puppet-dashboard/config/database.yml

修改时区

[iyunv@master ~]# vim /usr/share/puppet-dashboard/config/environment.rb

初始化数据库

[iyunv@master ~]# cd /usr/share/puppet-dashboard/[iyunv@master puppet-dashboard]# rake RAILS_ENV=production db:migrate

配置Apache  
我们需要整合Passenger和apache

[iyunv@master ~]# cat > /etc/httpd/conf.d/passenger.conf << EOF> LoadModule passenger_module modules/mod_passenger.so> > PassengerRoot /usr/share/rubygems/gems/passenger-3.0.17> PassengerRuby /usr/bin/ruby> PassengerHighPerformance on> PassengerMaxPoolSize 12> PassengerPoolIdleTime 1500> PassengerStatThrottleRate 120> RailsAutoDetect On> > > ServerName master.fisteam2.com> DocumentRoot "/usr/share/puppet-dashboard/public/"> > Options None> AllowOverride AuthConfig> Order allow,deny> allow from all> > ErrorLog /var/log/httpd/master.fisteam2.com_error.log> LogLevel warn> CustomLog /var/log/httpd/master.fisteam2.com_access.log combined> ServerSignature On> > EOF[iyunv@master ~]#

启动服务

[iyunv@master ~]# service httpd startStarting httpd: httpd: Could not reliably determine the server's fully qualified domain name, using master.fisteam2.com for ServerName[ OK ][iyunv@master ~]# chkconfig httpd on[iyunv@master ~]# chkconfig --list | grep httpdhttpd 0:off 1:off 2:on 3:on 4:on 5:on 6:off

配置puppet  
让Dashboard使用Reports，现在默认agent是已经启用Report的功能，所以你就不需要设置agent,你只需要设置Server端就可以

[iyunv@master ~]# vim /etc/puppet/puppet.conf[master]reports = store,httpreporturl = http://master.fisteam2.com:80/reports/upload

重启puppetmaster 服务

[iyunv@master ~]# service puppetmaster restart

这时候就可以直接用 http://ip 访问puppet Dashboard

导入报告

[iyunv@master puppet-dashboard]# cd /usr/share/puppet-dashboard/[iyunv@master puppet-dashboard]# rake RAILS_ENV=production reports:import

这时候你访问Dashboard,可以看到导入的任务.

4. 执行导入的reports

[iyunv@master puppet-dashboard]# cd /usr/share/puppet-dashboard/[iyunv@master puppet-dashboard]# rake jobs:work RAILS_ENV="production"

一个Master,五个node测试效果

文件同步测试

Puppet master:

[iyunv@master ~]# vim /etc/puppet/fileserver.conf[fisteam2filesync]path /etc/puppetallow *

在下面加一个配置域，名字叫做fisteam2filesync,路径是/etc/puppet

[iyunv@master ~]# vim /etc/puppet/manifests/site.ppnode default {file {"/tmp/fisteam2_puppet_testfile.txt":content=>"good,test pass!fisteam2_puppet_testing";}}

上面的代码对默认连入的puppet客户端执行一个操作,在/tmp目录生成一个fisteam2_puppet_testfile.txt文件,内容是good,test pass! 回车换行fisteam2_puppet_testing回车换行.  
初次创建pp文件，需要重启puppetmaster

[iyunv@master ~]# service puppetmaster restartStopping puppetmaster: [ OK ]Starting puppetmaster: [ OK ]
