Puppet3在CentOS6.5叢集下的安裝，puppet3centos6.5

環境：3台主機，

IP分別為10.211.55.11、12、13

puppet master安裝在10.211.55.11

puppet agent安裝在10.211.55.11、12、13

 

1、安裝EPEL庫 後面安裝puppet Dashboard需要

yum install yum-prioritiesrpm -ivh https://dl.fedoraproject.org/pub/epel/epel-release-latest-6.noarch.rpm rpm —import https://dl.fedoraproject.org/pub/epel/RPM-GPG-KEY-EPEL-6

其中源可以替換為國內鏡像

http://mirrors.ustc.edu.cn/fedora/epel/epel-release-latest-6.noarch.rpmhttp://mirrors.ustc.edu.cn/fedora/epel/RPM-GPG-KEY-EPEL-6

修改/etc/yum.repos.d/epel.repo檔案

在[epel]最後添加一條屬性

priority=11

意思是yum先去官方源查，官方沒有再去epel的源找

 

2、在10.211.55.11上安裝dnsmasq網域名稱解析服務

yum install dnsmasqchkconfig dnsmasq onservice dnsmasq startlokkit -p 53:udp(開啟iptables 53連接埠)echo "10.211.55.11 node01.myhost.com" >> /etc/hosts 

修改dnsmasq.conf

interface=eth0listen-address=10.211.55.11bind-interfacesresolv-file=/etc/resolv.confaddn-hosts=/etc/hosts

三台主機上分別輸入

echo “nameserver 10.211.55.11” >> /etc/resolv.conf

改主機名稱

vi /etc/sysconfig/network 分別改為node01.myhost.com、node02.myhost.com、node03.myhost.com

驗證DNS是否成功

netstat -tunlp|grep 53dig node02.myhost.com

 

3、在10.211.55.11安裝時間同步伺服器

yum install ntpchkconfig ntpd onservice ntpd start

（待完善）

 

4、安裝Puppet

安裝官方源

rpm -ivh http://yum.puppetlabs.com/puppetlabs-release-el-6.noarch.rpm

匯入GPG密鑰（驗證封裝的完整性）

rpm --import http://yum.puppetlabs.com/RPM-GPG-KEY-puppetlabs

 

安裝

yum install puppet-serverservice puppetmaster startservice puppet startchkconfig puppetmaster onchkconfig puppet on

編輯/etc/puppet/puppet.conf

[agent]server = node01.myhost.com

自動簽名

cat > /etc/puppet/autosign.conf <

測試連接

puppet agent -t

刪除認證

find /var/lib/puppet/ssl -name localhost.pem -delete

常用資訊

puppet cert list -all（查看所有認證）cat /etc/sysconfig/puppet（預設配置）/var/lib/puppet （agent認證位置）/etc/puppet/puppet.conf （設定檔）/usr/share/puppet （安裝位置）puppet config print modulepath（查看模組位置）puppet agent -t --summarize（查看報告）

 

5、安裝Dashboard 安裝

yum install -y mysql mysql-devel mysql-server httpd mod_passenger puppet-dashboard

mod_passenger是讓apache支援ruby

配置：

/etc/my.cnf,

在[mysqld]欄位,增加最後一行

# Allowing 32MB allows an occasional 17MB row with plenty of spare roommax_allowed_packet = 32M

/etc/init.d/mysqld startchkconfig mysqld onchkconfig httpd  onservice httpd startmysqladmin -u root password 'password'

建立一個dashboard資料庫

mysql -uroot -ppassword <

編輯 /usr/share/puppet-dashboard/config/database.yml

production:  database: dashboard  username: dashboard  password: password  encoding: utf8  adapter: mysql

修改時區 /usr/share/puppet-dashboard/config/environment.rb

#config.time_zone = 'UTC'  config.time_zone = 'Beijing'

初始化資料庫

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

配置Apache

cat > /etc/httpd/conf.d/passenger.conf << EOFLoadModule 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 node01.myhost.com       DocumentRoot "/usr/share/puppet-dashboard/public/"       <Directory "/usr/share/puppet-dashboard/public/">          Options None          AllowOverride AuthConfig          Order allow,deny                  allow from all              ErrorLog /var/log/httpd/node01.myhost.com_error.log       LogLevel warn       CustomLog /var/log/httpd/node06.chenshake.com_access.log combined       ServerSignature On    EOF/etc/init.d/httpd startchkconfig httpd onlokkit -p 80:tcp

配置puppet

# puppet.conf (on puppet master)  [master]    reports = store, http    reporturl = http://node06.chenshake.com:80/reports/upload

/etc/init.d/puppetmaster restart

 

匯入報告

cd /usr/share/puppet-dashboardrake gems:refresh_specsrake RAILS_ENV=production reports:importDelayed Job Workersenv RAILS_ENV=production /usr/share/puppet-dashboard/script/delayed_job -p dashboard -n 4 -m startps -ef|grep delayed_job|grep -v grepenv RAILS_ENV=production /usr/share/puppet-dashboard/script/delayed_job -p dashboard -n 4 -m stop

這個時候你才能在Dashbaord裡看到資料

 

6、安裝Foreman （待完善）
