在CentOS 6.4上安装Puppet配置管理工具

五052013　　


上篇说了下在ubuntu12.04上安装puppet，安装的版本为puppet2.7.11版本，今天尝试了下在CentOS6.4系统上安装puppet 3.1.1版本,本文参考chenshake的文章



?

1 2 3 4

OS:centso 6.4 X64 Puppet 3.1.1 Puppet master: master.canghai.com Puppet clients:node1-5.canghai.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-6.4-x86_64-minimal.iso最小化安装，因此先要安装ntp、wget等常用工具
安装ntp wget



?

1	yum install wget ntp -y

　　关闭selinux



?

1 2	sed -i '/SELINUX/ s/enforcing/disabled/g' /etc/selinux/config setenforce 0

　　停止iptables



?

1 2 3 4

chkconfig ip6tables off chkconfig iptables off /etc/init.d/ip6tables stop /etc/init.d/iptables stop

　　设置ntp




?

1 2 3

ntpdate pool.ntp.org chkconfig ntp on service ntpd start

　　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：



?

1 2 3

wget http://yum.puppetlabs.com/el/6/products/x86_64/puppetlabs-release-6-7.noarch.rpm rpm -ivh puppetlabs-release-6-7.noarch.rpm yum update

　　在 master上安装和启用 puppet 服务：



?

1 2 3

yum install puppet-server chkconfig puppet on service puppetmaster start

　　在clients上安装puppet客户端



?

1 2 3

yum install puppet chkconfig puppet on service puppet start

　　3.配置puppet
对于puppet 客户端，修改/etc/puppet/puppet.conf，指定master服务器



?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28

vi /etc/puppet/puppet.conf [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.canghai.com

　　并重启puppet服务



?

1	service puppet restart

　　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）



?

1 2 3 4

cat > /etc/puppet/autosign.conf <<EOF *.canghai.com EOF service puppetmaster restart

　　这样就会对所有来自canghai.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



?

1	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



?

1	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



?

1 2 3 4 5 6 7

puppet cert list --all + "master.canghai.com" (SHA256) CA:50:6A:51:D5:AD:F0:73:BF:83:A0:4A:BF:1F:4E:F0:56:C9:4B:D8:4D:BB:62:10:EE:14:16:D5:96:D0:B6:F7 (alt names: "DNS:master.canghai.com", "DNS:puppet", "DNS:puppet.canghai.com") + "node1.canghai.com" (SHA256) B8:95:69:2B:7B:3E:F4:38:CA:63:BE:A0:ED:3C:E7:05:1F:93:53:2D:1C:60:67:E9:D8:20:99:90:B8:9B:D6:40 + "node2.canghai.com" (SHA256) 6C:65:34:9D:B1:82:35:24:EF:3F:10:2B:10:F0:0B:44:42:AB:84:42:29:B5:73:1A:A0:1D:D5:1E:9E:24:BC:E3 + "node3.canghai.com" (SHA256) 57:54:33:37:23:A7:CD:BE:F6:25:BD:6F:E3:DA:F9:57:48:50:C7:5E:36:8F:F4:BA:C8:27:DF:B0:A2:84:5F:AF + "node4.canghai.com" (SHA256) 65:2F:0E:E7:98:F5:05:40:31:2F:FF:36:A5:3E:DE:C1:91:E8:45:16:55:60:A1:82:74:BC:84:EC:BA:C0:62:F0 + "node5.canghai.com" (SHA256) 8C:1B:31:B6:C0:9C:A5:AF:89:6C:85:1B:BA:D0:03:63:07:4C:B1:89:D4:E6:B7:4E:CA:4A:23:C7:3C:5F:CA:3D

　　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，撸过没有签名的，可以用



?

1	puppet cert --sign node1.canghai.com

　　进行签发证书,签发后在master，执行



?

1	puppet cert list --all

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



?

1	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



?

1 2 3 4 5 6 7 8 9 10 11

cat /etc/my.cnf [mysqld] datadir=/var/lib/mysql socket=/var/lib/mysql/mysql.sock user=mysql # Disabling symbolic-links is recommended to prevent assorted security risks symbolic-links=0 max_allowed_packet = 32M [mysqld_safe] log-error=/var/log/mysqld.log pid-file=/var/run/mysqld/mysqld.pid

　　启动服务



?

1 2	/etc/init.d/mysqld start chkconfig mysqld on

　　设置mysql密码，我这里使用是密码是123456



?

1	mysqladmin -u root password '123456'

　　创建一个dashboard数据库



?

1 2 3 4 5 6

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

　　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



?

1 2 3

wget http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm rpm -ivh epel-release-6-8.noarch.rpm yum install mod_passenger puppet-dashboard

　　配置Dashboard



?

1 2 3 4 5 6 7

vi /usr/share/puppet-dashboard/config/database.yml production:   database: dashboard   username: dashboard   password: 123456   encoding: utf8   adapter: mysql

　　修改时区



?

1 2 3 4

vi /usr/share/puppet-dashboard/config/environment.rb   #config.time_zone = 'UTC'   config.time_zone = 'Beijing'

　　初始化数据库



?

1 2	cd /usr/share/puppet-dashboard/ rake RAILS_ENV=production db:migrate

　　配置Apache
我们需要整合Passenger和apache



?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25

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.canghai.com DocumentRoot "/usr/share/puppet-dashboard/public/" &lt;Directory "/usr/share/puppet-dashboard/public/"&gt; Options None AllowOverride AuthConfig Order allow,deny allow from all ErrorLog /var/log/httpd/master.canghai.com_error.log LogLevel warn CustomLog /var/log/httpd/master.canghai.com_access.log combined ServerSignature On EOF

　　启动服务



?

1 2	/etc/init.d/httpd start chkconfig httpd on

　　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



?

1 2 3 4

vi /etc/puppet/puppet.conf [master] reports = store, http reporturl = http://master.canghai.com:80/reports/upload

　　重启puppetmaster 服务



?

1	/etc/init.d/puppetmaster restart

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

导入报告



?

1 2	cd /usr/share/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



?

1 2	cd /usr/share/puppet-dashboard rake jobs:work RAILS_ENV="production"
