Puppet3在CentOS6.5集羣下的安裝

環境：3臺主機，

IP分別爲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

1 2 3

yum install yum-priorities rpm -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

其中源可以替換爲國內鏡像

1 2	http://mirrors.ustc.edu.cn/fedora/epel/epel-release-latest-6.noarch.rpm http://mirrors.ustc.edu.cn/fedora/epel/RPM-GPG-KEY-EPEL-6

修改/etc/yum.repos.d/epel.repo文件

在[epel]最後添加一條屬性

1	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域名解析服務

1 2 3 4 5

yum install dnsmasq chkconfig dnsmasq on service dnsmasq start lokkit -p 53:udp(打開iptables 53端口) echo "10.211.55.11 node01.myhost.com" >> /etc/hosts

修改dnsmasq.conf

1 2 3 4 5

interface=eth0 listen-address=10.211.55.11 bind-interfaces resolv-file=/etc/resolv.conf addn-hosts=/etc/hosts

三臺主機上分別輸入

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

改主機名

1 2	vi /etc/sysconfig/network  分別改爲node01.myhost.com、node02.myhost.com、node03.myhost.com

驗證DNS是否成功

1 2	netstat -tunlp|grep 53 dig node02.myhost.com

 

3、在10.211.55.11安裝時間同步服務器

1 2 3

yum install ntp chkconfig ntpd on service ntpd start

（待完善）

 

4、安裝Puppet

安裝官方源

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

導入GPG密鑰（驗證包的完整性）

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

 

安裝

1 2 3 4 5

yum install puppet-server service puppetmaster start service puppet start chkconfig puppetmaster on chkconfig puppet on

編輯/etc/puppet/puppet.conf

1 2	[agent] server = node01.myhost.com

自動簽名

1	cat > /etc/puppet/autosign.conf <

測試連接

1	puppet agent -t

刪除證書

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

常用信息

1 2 3 4 5 6 7

puppet cert list -all（查看所有證書） cat /etc/sysconfig/puppet（默認配置） /var/lib/puppet （agent證書位置） /etc/puppet/puppet.conf （配置文件） /usr/share/puppet （安裝位置） puppet config print modulepath（查看模塊位置） puppet agent -t --summarize（查看報告）

 

5、安裝Dashboard 安裝

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

mod_passenger是讓apache支持ruby

配置：

/etc/my.cnf,

在[mysqld]字段,增加最後一行

1 2	# Allowing 32MB allows an occasional 17MB row with plenty of spare room max_allowed_packet = 32M

1 2 3 4 5

/etc/init.d/mysqld start chkconfig mysqld on chkconfig httpd  on service httpd start mysqladmin -u root password 'password'

創建一個dashboard數據庫

1	mysql -uroot -ppassword <

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

1 2 3 4 5 6

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

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

1 2	#config.time_zone = 'UTC'   config.time_zone = 'Beijing'

初始化數據庫

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

配置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 26 27 28 29 30 31

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 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 start chkconfig httpd on lokkit -p 80:tcp

配置puppet

1 2 3 4

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

/etc/init.d/puppetmaster restart

 

導入報告

1 2 3 4 5 6 7 8

cd /usr/share/puppet-dashboard rake gems:refresh_specs rake RAILS_ENV=production reports:import   Delayed Job Workers env RAILS_ENV=production /usr/share/puppet-dashboard/script/delayed_job -p dashboard -n 4 -m start ps -ef|grep delayed_job|grep -v grep env 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裏看到數據

 

6、安裝Foreman （待完善）
