Puppet运维实战

foreman架构的引入3-安装Foreman1.5.3架构（all-in-one）

注意：本实验是在离线情况下安装的，所以需要在本地创建自己的yum仓库，创建方法可参考《如何根据版本制作属于自己的puppet yum源》，如何你实在是比较懒或者搞不定rpm包之间的依赖关系，那就去我的github上下载吧：https://github.com/kisspuppet/foreman-repo

更多安装细节请参考官网：http://theforeman.org/manuals/1.5/index.html#Releasenotesfor1.5.4

以下all-in-one安装方式跟官方安装的有所区别，官方安装可能只需要一条命令就可以安装成功，在我测试下来发现会出现有时候成功，有时候不成功的现象，所以改成了以下方式安装，而且每次都能成功，条例也比较清晰，为后面拆分puppetmaster能够提供很好的帮助。

1、软件包的选型如下：

  • puppet-server 3.6.2
  • puppet 3.6.2
  • facter 2.0.2
  • mcollective 2.2.4
  • rabbitmq-server 3.2.4
  • foreman 1.5.3
  • foreman-proxy 1.5.4

2、系统环境准备

系统版本：

[root@foreman02 yum.repos.d]# cat /etc/redhat-release 
Red Hat Enterprise Linux Server release 6.5 (Santiago)

网络参数：

[root@foreman02 yum.repos.d]# ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN 
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether 00:50:56:a6:5c:70 brd ff:ff:ff:ff:ff:ff
    inet 192.168.10.159/24 brd 192.168.10.255 scope global eth0
    inet6 fe80::250:56ff:fea6:5c70/64 scope link 
       valid_lft forever preferred_lft forever

主机名称：

[root@foreman02 yum.repos.d]# hostname -f
foreman02.kisspuppet.com
[root@foreman02 yum.repos.d]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.10.159  foreman02.kisspuppet.com  foreman02

平台环境：

[root@foreman02 yum.repos.d]# uname -r
2.6.32-431.el6.x86_64

yum仓库：

[root@foreman02 yum.repos.d]# cat foreman153.repo 
[foreman]
name=Foreman
baseurl=ftp://192.168.10.254/blog/foreman
enabled=1
gpgcheck=0

[puppet]
name=puppet
baseurl=ftp://192.168.10.254/blog/puppet-el6
enabled=1
gpgcheck=0

[rhel]
name=RHEL
baseurl=ftp://192.168.10.254/rhel6.5
enabled=1
gpgcheck=0

网络安全环境：

[root@foreman02 ~]# /etc/init.d/iptables status
iptables: Firewall is not running.
[root@foreman02 ~]# getenforce 
Disabled

3、安装Foreman

3.1、安装puppetmaster，并生成CA和证书

[root@foreman02 ~]# yum install foreman-installer
[root@foreman02 ~]# yum install puppet-server puppet facter
[root@foreman02 ~]# vim /etc/puppet/puppet.conf
[master]
    certname = foreman02.kisspuppet.com

[root@foreman02 ~]# /etc/init.d/puppetmaster start
Starting puppetmaster:                                     [  OK  ]
[root@foreman02 ~]# puppet  cert --list --all
+ "foreman02.kisspuppet.com" (SHA256) 1D:7E:90:F5:16:7D:01:67:77:37:EE:31:3F:46:AD:0A:47:80:B6:DF:6A:5E:25:A8:DE:BA:78:45:C9:09:D6:BD (alt names: "DNS:foreman02.kisspuppet.com", "DNS:puppet", "DNS:puppet.kisspuppet.com")
[root@foreman02 ~]# /etc/init.d/puppetmaster stop
Stopping puppetmaster:                                     [  OK  ]

3.2、安装foreman及依赖包

[root@foreman02 ~]# yum install foreman  mod_passenger mod_ssl ruby193-rubygem-passenger-native mysql mysql-server foreman-mysql2

3.3、通过foreman-installer安装foreman

foreman默认安装选择的数据库为postgresql，这里选用mysql进行安装。

[root@foreman02 ~]# foreman-installer --foreman-db-adapter mysql2 --foreman-db-type mysql --no-enable-puppet --no-enable-foreman-proxy --foreman-configure-epel-repo=false
Installing             Done                                               [100%] [...................]
  Success!
  * Foreman is running at https://foreman02.kisspuppet.com
      Default credentials are 'admin:changeme'
  The full log is at /var/log/foreman-installer/foreman-installer.log

安装完成之后，通过火狐或者谷歌浏览器访问看是否安装成功https://192.168.10.159

3.4、安装foreman-proxy及依赖包

[root@foreman02 ~]# yum install tftp-server syslinux foreman-proxy

3.5、安装foreman-proxy，并通过foreman-installer重新安装foreman和puppetmaster

注意：以下方式是安装后会代理TFTP, DNS, DHCP, Puppet, and Puppet CA，并且puppetmaster会以apache+passenger的方式安装运行。

[root@foreman02 ~]# foreman-installer --enable-foreman --enable-foreman-proxy --enable-puppet  --puppet-server=true --foreman-proxy-puppetrun=true  --foreman-proxy-puppetca=true   --foreman-proxy-dhcp=true  --foreman-proxy-tftp=true  --foreman-proxy-dns=true --foreman-proxy-dns-interface=eth0 --foreman-proxy-dns-zone=kisspuppet.com  --foreman-proxy-dns-reverse=10.168.192.in-addr.arpa  --foreman-proxy-dns-forwarders=8.8.8.8 --foreman-proxy-dns-forwarders=8.8.4.4 --foreman-configure-epel-repo=false  --foreman-proxy-register-in-foreman=false 

Installing             Done                                               [100%] [...................]
  Success!
  * Foreman is running at https://foreman02.kisspuppet.com
      Default credentials are 'admin:changeme'
  * Foreman Proxy is running at https://foreman02.kisspuppet.com:8443
  * Puppetmaster is running at port 8140
  The full log is at /var/log/foreman-installer/foreman-installer.log

如果只代理puppet和puppetCA，可以通过以下方式安装

[root@foreman02 ~]# foreman-installer --enable-foreman --enable-foreman-proxy --enable-puppet  --puppet-server=true --foreman-proxy-puppetrun=true  --foreman-proxy-puppetca=true    --foreman-configure-epel-repo=false  --foreman-proxy-register-in-foreman=false

4、检查foreman、foreman-proxy、puppetmaster是否安装成功

[root@foreman02 ~]# /etc/init.d/httpd status
httpd (pid  25433) is running...
[root@foreman02 ~]# /etc/init.d/foreman-proxy status
foreman-proxy (pid  25605) is running...

[root@foreman02 ~]# netstat -naltp | grep 8443
tcp        0      0 0.0.0.0:8443                0.0.0.0:*                   LISTEN      25605/ruby          
[root@foreman02 ~]# netstat -naltp | grep 80
tcp        0      0 :::80                       :::*                        LISTEN      25433/httpd         
[root@foreman02 ~]# netstat -naltp | grep 8140
tcp        0      0 :::8140                     :::*                        LISTEN      25433/httpd

5、在Foreman上注册foreman-proxy

如果要管理puppet、puppetca等软件，是需要通过foreman-proxy去代理才能够正常使用的，关于代理的开启和关闭可以修改它的配置文件/etc/foreman-proxy/settings.yml
