OS:CentOS-6.5-x86_64

Puppet 3.7.3

Puppet master: master.fisteam2.com

Puppet clients:node1-5.fisteam2.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-6.5-x86_64.iso 进行 minimal 最小化安装

关闭 selinux
[root@master ~]# cat /etc/selinux/config

# This file controls the state of SELinux on the system.

# SELINUX= can take one of these three values:

# enforcing – SELinux security policy is enforced.

# permissive – SELinux prints warnings instead of enforcing.

# disabled – No SELinux policy is loaded.

SELINUX=enforcing

# SELINUXTYPE= can take one of these two values:

# targeted – Targeted processes are protected,

# mls – Multi Level Security protection.

SELINUXTYPE=targeted

[root@master ~]# sed -i ‘/SELINUX/ s/enforcing/disabled/g’ /etc/selinux/config

[root@master ~]# cat /etc/selinux/config

# This file controls the state of SELinux on the system.

# SELINUX= can take one of these three values:

# enforcing – SELinux security policy is enforced.

# permissive – SELinux prints warnings instead of enforcing.

# disabled – No SELinux policy is loaded.

SELINUX=disabled

# SELINUXTYPE= can take one of these two values:

# targeted – Targeted processes are protected,

# mls – Multi Level Security protection.

SELINUXTYPE=targeted

[root@master ~]# setenforce 0

停止 iptables
[root@node1 ~]# chkconfig –list |grep tables

ip6tables 0:off 1:off 2:on 3:on 4:on 5:on 6:off

iptables 0:off 1:off 2:on 3:on 4:on 5:on 6:off

[root@node1 ~]# chkconfig ip6tables off

[root@node1 ~]# chkconfig iptables off

[root@node1 ~]# service ip6tables stop

ip6tables: Setting chains to policy ACCEPT: filter [OK]

ip6tables: Flushing firewall rules: [OK]

ip6tables: Unloading modules: [OK]

[root@node1 ~]# service iptables stop

iptables: Setting chains to policy ACCEPT: filter [OK]

iptables: Flushing firewall rules: [OK]

iptables: Unloading modules: [OK]

[root@node1 ~]#

设置 ntp
[root@master ~]# ntpdate pool.ntp.org

[root@master ~]# chkconfig –list|grep ntp

ntpd 0:off 1:off 2:off 3:off 4:off 5:off 6:off

ntpdate 0:off 1:off 2:off 3:off 4:off 5:off 6:off

[root@master ~]# chkconfig ntpd on

[root@master ~]# service ntpd start

Starting ntpd: [OK]

[root@master ~]#

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:
[root@master ~]# wget http://yum.puppetlabs.com/el/6/products/x86_64/puppetlabs-release-6-7.noarch.rpm

[root@master ~]# rpm -ivh puppetlabs-release-6-7.noarch.rpm

[root@master ~]#yum update

在 master 上安装和启用 puppet 服务:
[root@master ~]# yum install puppet-server

[root@master ~]# chkconfig –list |grep puppet

puppet 0:off 1:off 2:off 3:off 4:off 5:off 6:off

puppetmaster 0:off 1:off 2:off 3:off 4:off 5:off 6:off

[root@master ~]# chkconfig puppet on

[root@master ~]# service puppetmaster start

Starting puppetmaster: [OK]

[root@master ~]#

在 clients 上安装 puppet 客户端

[root@node1 ~]# yum install puppet

[root@node1 ~]# chkconfig –list |grep puppet

puppet 0:off 1:off 2:off 3:off 4:off 5:off 6:off

[root@node1 ~]# chkconfig puppet on

[root@node1 ~]# chkconfig –list |grep puppet

puppet 0:off 1:off 2:on 3:on 4:on 5:on 6:off

[root@node1 ~]# service puppet start

Starting puppet agent: [OK]

[root@node1 ~]#

3. 配置 puppet

对于 puppet 客户端,修改 /etc/puppet/puppet.conf,指定 master 服务器
[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.fisteam2.com

并重启 puppet 服务
[root@node1 ~]# service puppet restart

Stopping puppet agent: [OK]

Starting puppet agent: [OK]

[root@node1 ~]#

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)
[root@master ~]# ll /etc/puppet/

total 28

-rw-r–r–. 1 root root 4178 Nov 4 06:24 auth.conf

drwxr-xr-x. 3 root root 4096 Dec 29 15:44 environments

-rw-r–r–. 1 root root 1462 Nov 4 06:23 fileserver.conf

drwxr-xr-x. 2 root root 4096 Nov 4 06:24 manifests

drwxr-xr-x. 2 root root 4096 Nov 4 06:24 modules

-rw-r–r–. 1 root root 853 Nov 4 06:23 puppet.conf

[root@master ~]# cat > /etc/puppet/autosign.conf <<EOF

> *.fisteam2.com

> EOF

[root@master ~]# service puppetmaster restart

Stopping puppetmaster: [OK]

Starting puppetmaster: [OK]

[root@master ~]#

这样就会对所有来自 fisteam2.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
[root@master ~]# 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
[root@node1 ~]# puppet agent –no-daemonize –onetime –verbose –debug

CentOS6.5+Puppet3.7.3 安装、配置及测试

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
[root@master ~]# puppet cert list –all

CentOS6.5+Puppet3.7.3 安装、配置及测试

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,如果没有签名的,可以用
[root@master ~]# puppet cert –sign node1.localdomain

CentOS6.5+Puppet3.7.3 安装、配置及测试

即可看到证书已经签发。

5. 在服务端安装 puppet 的 dashboard

安装 mysql
[root@master ~]# 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
[root@master ~]# vim /etc/my.cnf

CentOS6.5+Puppet3.7.3 安装、配置及测试

启动 Mysql 服务

[root@master ~]# service mysqld start

[root@master ~]# chkconfig mysqld on 

[root@master ~]# chkconfig --list |grep mysqld 

mysqld 0:off 1:off 2:on 3:on 4:on 5:on 6:off

CentOS6.5+Puppet3.7.3 安装、配置及测试

设置 mysql 密码,我这里使用是密码是 123456
[root@master ~]# mysqladmin -u root password ‘123456’

创建一个 dashboard 数据库
[root@master ~]# 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

[root@master ~]

CentOS6.5+Puppet3.7.3 安装、配置及测试

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

[root@master ~]# wget http://dl.Fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

[root@master ~]# rpm -ivh epel-release-6-8.noarch.rpm
