多puppetmaster，多ca，keepalived+haproxy（nginx）puppet集群搭建
一、服务器详情
192.168.122.111 pm01.jq.com pm01 #（puppetmaster服务器）
192.168.122.112 pm02.jq.com pm02 #（puppetmaster服务器）
192.168.122.121 ag01.jq.com ag01 #（puppet agent服务器）
192.168.122.122 ag02.jq.com ag02 #（puppet agent服务器）
192.168.122.131 ca01.jq.com ca01 #（puppet ca服务器）
192.168.122.132 ca02.jq.com ca02 #（puppet ca服务器）
192.168.122.141 lvs01.jq.com lvs01 #（puppet 负载服务器）
192.168.122.142 lvs02.jq.com lvs02 #（puppet 负载服务器）
#vip暂时用于测试，使用ip addr的方式绑定，后续用高可用软件实现bind
192.168.122.130 pc.jq.com pc #（ca服务器的vip，前期绑定在ca01服务器上）
192.168.122.115 lvs.jq.com lvs #（负载服务器的vip，前期绑定在puppetmaster上，后期需要绑定在lvs服务器上）
二、CA服务器部署
CA服务器单独用于签署和撤销证书，当puppetCA服务不可用时，新的客户端将不能获得证书，从而会影响使用，而已签发证书的客户端缺不受影响。因此将CA进行独立队架构，这对容错性而言是非常有必要的。
2.1 安装软件包
[[email protected] ~]# groupadd -g 3000 puppet
[[email protected] ~]# useradd -u 3000 -g 3000 puppet
[[email protected] ~]# yum install puppet puppet-server –y
2.2 bind vip
绑定ca的vip 192.168.122.130到ca01服务器
[[email protected] ~]#ip addr add 192.168.122.130/24 dev eth0
2.3 生成证书
使用puppet cert命令生成CA服务器与服务器域名证书。生成pc.jq.com和lvs.jq.com两个域名的授权证书文件,前面是证书别名，后面是证书名称。
[[email protected] ssl]# puppet cert --generate --dns_alt_names pc pc.jq.com
[[email protected] ssl]# puppet cert --generate --dns_alt_names lvs lvs.jq.com [[email protected] ssl]# puppet cert --list --all
+ "lvs.jq.com" (SHA256) D6:5B:51:D6:6E:35:61:A4:45:D8:37:17:5B:85:A1:1B:34:BB:2F:D7:48:E8:44:57:B7:1D:42:8E:11:18:81:34 (alt names: "DNS:lvs", "DNS:lvs.jq.com")
+ "pc.jq.com" (SHA256) A7:71:E1:46:1E:F0:F1:70:72:E3:B5:16:03:91:17:6D:68:5B:55:39:B6:79:6B:30:DD:41:ED:10:21:27:2A:33 (alt names: "DNS:pc", "DNS:pc.jq.com")
2.4 配置puppet.conf，添加标签[master]
[[email protected] ~]# cat /etc/puppet/puppet.conf | grep -v "#"
[main]
logdir = /var/log/puppet
rundir = /var/run/puppet
ssldir = $vardir/ssl
pluginsync = false
[agent]
classfile = $vardir/classes.txt
localconfig = $vardir/localconfig
server = lvs.jq.com
ca_server = pc.jq.com
environment = jqprd
[master]
confdir = /etc/puppet
certname = pc.jq.com
ca = true #开启CA认证
2.5 启动puppetmaster，CA部署完成
[[email protected] ~]# /etc/init.d/puppetmaster start
[[email protected] ~]# chkconfig puppetmaster on
2.6 ca02服务部署
ca02跟ca01的部署方式完全一致，证书是从ca01 拷贝过来的。直接copy /var/lib/ssl/puppet目录
三、PuppetMaster服务器部署
PuppetMaster服务器部署可采用默认的WebRick方式，也可以采用apache+passenger或nginx+passenger方式。
3.1 WebRick方式：
3.1.1 安装软件包
[[email protected] ~]# groupadd -g 3000 puppet
[[email protected] ~]# useradd -u 3000 -g 3000 puppet
[[email protected] ~]# yum install puppet puppet-server -y
3.1.2 设置hosts文件
[[email protected] ~]# vim /etc/hosts
192.168.122.111 pm01.jq.com pm01
192.168.122.112 pm02.jq.com pm02
192.168.122.121 ag01.jq.com ag01
192.168.122.122 ag02.jq.com ag02
192.168.122.131 ca01.jq.com ca01
192.168.122.132 ca02.jq.com ca02
192.168.122.141 lvs01.jq.com lvs01
192.168.122.142 lvs02.jq.com lvs02
192.168.122.130 pc.jq.com pc
192.168.122.115 lvs.jq.com lvs
3.1.3 bind master vip
绑定LVS的vip 192.168.122.115到pm01服务器，测试用，在没有负载之前，绑定在master上。
ip addr add 192.168.122.115/24 dev eth0
3.1.4 创建证书目录
[[email protected] ~]# mkdir /var/lib/puppet/ssl/{certs,ca,private_keys} –p
3.1.5 将puppetca上生成的puppetmaster公钥、私钥和根证书复制到pm01
scp -r [email protected]:/var/lib/puppet/ssl/ca/signed/lvs.jq.com.pem /var/lib/puppet/ssl/certs/lvs.jq.com.pem
scp -r [email protected]:/var/lib/puppet/ssl/ca/ca_crt.pem /var/lib/puppet/ssl/certs/ca.pem
scp -r [email protected]:/var/lib/puppet/ssl/private_keys/lvs.jq.com.pem /var/lib/puppet/ssl/private_keys/lvs.jq.com.pem
scp -r [email protected]:/var/lib/puppet/ssl/ca/ca_crl.pem /var/lib/puppet/ssl/ca/ca_crl.pem
3.1.6 配置puppet.conf，添加标签[master]，关闭ca
[[email protected] ~]# grep -v "#" /etc/puppet/puppet.conf
[main]
logdir = /var/log/puppet
rundir = /var/run/puppet
ssldir = $vardir/ssl
privatekeydir = $ssldir/private_keys { group = service }
hostprivkey = $privatekeydir/$certname.pem { mode = 640 }
[agent]
classfile = $vardir/classes.txt
localconfig = $vardir/localconfig
server = lvs.jq.com #puppetmaster域名，应该与之前手动生成的证书匹配
ca_server = pc.jq.com #ca证书服务器
[master]
certname = lvs.jq.com #puppetmaster的域名，应该与之前手动生成的证书匹配
ca = false #关闭ca验证
3.1.7 启动puppetmaster服务，puppetmaster部署完成
[[email protected] ssl]# /etc/init.d/puppetmaster restart
3.1.8 运行puppet命令进行本地证书申请
[[email protected] ssl]# puppet agent -t
Info: Creating a new SSL key for pm01.jq.com
Info: csr_attributes file loading from /etc/puppet/csr_attributes.yaml
Info: Creating a new SSL certificate request for pm01.jq.com

Exiting; no certificate found and waitforcert is disabled
3.1.9 登录puppetca进行证书签发
[[email protected] ~]# puppet cert --sign pm01.jq.com
Notice: Signed certificate request for pm01.jq.com
Notice: Removing file Puppet::SSL::CertificateRequest pm01.jq.com at ‘/var/lib/puppet/ssl/ca/requests/pm01.jq.com.pem‘
3.1.10 再次运行puppet命令进行测试连通性
[[email protected] ssl]# puppet agent -t

Notice: Finished catalog run in 0.17 seconds
3.1.11 在kspupt-ca上申请本地证书
[[email protected] ~]# vim /etc/puppet/puppet.conf
[agent]
server = lvs.jq.com
ca_server = pc.jq.com
[[email protected] ~]# puppet agent -t
[[email protected] ~]# puppet cert --sign ca01.jq.com

4.4 配置keepalived，取消vip 通过ip addr 绑定
Keepalived的备机配置略去，网上也可以搜索到，需要修改的地方很少。
[[email protected] ~]# cat /etc/keepalived/keepalived.conf
! Configuration File for keepalived
global_defs {
notification_email {
[email protected]
}
notification_email_from [email protected]
smtp_server 127.0.0.1

}
vrrp_script chk_http_port {
script "/etc/keepalived/check_haproxy.sh"
interval 2
weight 2
}
vrrp_instance VI_1 {
state MASTER
interface eth0
virtual_router_id 51
priority 100
advert_int 1
authentication {
auth_type PASS
auth_pass 1111
}
track_script {
chk_http_port
}
virtual_ipaddress {
192.168.122.115 #此处为负载的VIP，配置keepalived之后，切记去掉之前ip addr的绑定
}
}
4.4.1 Keepalived监控haproxy脚本
[[email protected] ~]# cat /etc/keepalived/check_haproxy.sh
#!/bin/bash
. /etc/profile
A=`ps -C haproxy --no-header |wc -l`
if [ $A -eq 0 ];then
/etc/init.d/haproxy start
sleep 3
if [ `ps -C haproxy --no-header |wc -l` -eq 0 ];then
/etc/init.d/keepalived stop
fi
fi
4.5 Lvs02服务器部署
Lvs02的配置与lvs01的配置完全一致，将此服务器作为lvs01的备机，包括keepalived+haproxy。
几乎照搬了http://kisspuppet.com/2014/10/21/puppet_learning_ext6/ 的文章，非常感谢kisspuppet！
