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 <*.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
5.在服务端安装puppet的dashboard
安装mysql
[root@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
[root@master ~]# vim /etc/my.cnf
启动Mysql服务
[root@master ~]# service mysqld start [root@master ~]# chkconfig mysqld on [root@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
[root@master ~]# mysqladmin -u root password '123456'
创建一个dashboard数据库
[root@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 [root@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
[root@master ~]# wget http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm [root@master ~]# rpm -ivh epel-release-6-8.noarch.rpm [root@master ~]# yum install mod_passenger puppet-dashboard
配置Dashboard
[root@master ~]# vim /usr/share/puppet-dashboard/config/database.yml
修改时区
[root@master ~]# vim /usr/share/puppet-dashboard/config/environment.rb
初始化数据库
[root@master ~]# cd /usr/share/puppet-dashboard/ [root@master puppet-dashboard]# rake RAILS_ENV=production db:migrate
配置Apache
我们需要整合Passenger和apache
[root@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/" > > EOF [root@master ~]#> 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 >
启动服务
[root@master ~]# service httpd start Starting httpd: httpd: Could not reliably determine the server's fully qualified domain name, using master.fisteam2.com for ServerName[ OK ] [root@master ~]# chkconfig httpd on [root@master ~]# chkconfig --list | grep httpd httpd 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
[root@master ~]# vim /etc/puppet/puppet.conf [master] reports = store,http reporturl = http://master.fisteam2.com:80/reports/upload
重启puppetmaster 服务
[root@master ~]# service puppetmaster restart
这时候就可以直接用 http://ip 访问puppet Dashboard
导入报告
[root@master puppet-dashboard]# cd /usr/share/puppet-dashboard/ [root@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
[root@master puppet-dashboard]# cd /usr/share/puppet-dashboard/ [root@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:
[root@master ~]# vim /etc/puppet/fileserver.conf [fisteam2filesync] path /etc/puppet allow *
在下面加一个配置域,名字叫做fisteam2filesync,路径是/etc/puppet
[root@master ~]# vim /etc/puppet/manifests/site.pp node default { file { "/tmp/fisteam2_puppet_testfile.txt": content=>"good,test pass!\nfisteam2_puppet_testing\n"; } }
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
[root@master ~]# service puppetmaster restart Stopping puppetmaster: [ OK ] Starting puppetmaster: [ OK ]
