CentOS6.4系统上安装puppet 3.1.1版本,本文参考chenshake的文章
|
OS:centso 6.4 X64
Puppet 3.1.1
Puppet master: master.canghai.com
Puppet clients:node1-5.canghai.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-6.4-x86_64-minimal.iso最小化安装，因此先要安装ntp、wget等常用工具
安装ntp wget
|
yum install wget ntp -y
|
关闭selinux
|
sed -i &＃39;/SELINUX/ s/enforcing/disabled/g&＃39; /etc/selinux/config
setenforce 0
|
停止iptables
|
chkconfig ip6tables off
chkconfig iptables off
/etc/init.d/ip6tables stop
/etc/init.d/iptables stop
|
设置ntp
|
ntpdate pool.ntp.org
chkconfig ntp on
service ntpd start
|
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：
|
wget http://yum.puppetlabs.com/el/6/products/x86_64/puppetlabs-release-6-7.noarch.rpm
rpm -ivh puppetlabs-release-6-7.noarch.rpm
yum update
|
在 master上安装和启用 puppet 服务：
|
yum install puppet-server
chkconfig puppet on
service puppetmaster start
|
在clients上安装puppet客户端
|
yum install puppet
chkconfig puppet on
service puppet start
|
3.配置puppet
对于puppet 客户端，修改/etc/puppet/puppet.conf，指定master服务器
|
vi /etc/puppet/puppet.conf
[main]
# The Puppet log directory.
# The default value is &＃39;$vardir/log&＃39;.
logdir = /var/log/puppet
# Where Puppet PID files are kept.
# The default value is &＃39;$vardir/run&＃39;.
rundir = /var/run/puppet
# Where SSL certificates are kept.
# The default value is &＃39;$confdir/ssl&＃39;.
ssldir = $vardir/ssl
[agent]
# The file in which puppetd stores a list of the classes
# associated with the retrieved configuratiion. Can be loaded in
# the separate ``puppet`` executable using the ``--loadclasses``
# option.
# The default value is &＃39;$confdir/classes.txt&＃39;.
classfile = $vardir/classes.txt
# Where puppetd caches the local configuration. An
# extension indicating the cache format is added automatically.
# The default value is &＃39;$confdir/localconfig&＃39;.
localcOnfig= $vardir/localconfig
server = master.canghai.com
|
并重启puppet服务
|
service puppet restart
|
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）
|
cat > /etc/puppet/autosign.conf <
*.canghai.com
EOF
service puppetmaster restart
|
这样就会对所有来自canghai.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
|
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
|
puppet agent --no-daemonize --onetime --verbose --debug
|
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
|
puppet cert list --all
+ "master.canghai.com" (SHA256) CA:50:6A:51:D5:AD:F0:73:BF:83:A0:4A:BF:1F:4E:F0:56:C9:4B:D8:4D:BB:62:10:EE:14:16:D5:96:D0:B6:F7 (alt names: "DNS:master.canghai.com", "DNS:puppet", "DNS:puppet.canghai.com")
+ "node1.canghai.com" (SHA256) B8:95:69:2B:7B:3E:F4:38:CA:63:BE:A0:ED:3C:E7:05:1F:93:53:2D:1C:60:67:E9:D8:20:99:90:B8:9B:D6:40
+ "node2.canghai.com" (SHA256) 6C:65:34:9D:B1:82:35:24:EF:3F:10:2B:10:F0:0B:44:42:AB:84:42:29:B5:73:1A:A0:1D:D5:1E:9E:24:BC:E3
+ "node3.canghai.com" (SHA256) 57:54:33:37:23:A7:CD:BE:F6:25:BD:6F:E3:DA:F9:57:48:50:C7:5E:36:8F:F4:BA:C8:27:DF:B0:A2:84:5F:AF
+ "node4.canghai.com" (SHA256) 65:2F:0E:E7:98:F5:05:40:31:2F:FF:36:A5:3E:DE:C1:91:E8:45:16:55:60:A1:82:74:BC:84:EC:BA:C0:62:F0
+ "node5.canghai.com" (SHA256) 8C:1B:31:B6:C0:9C:A5:AF:89:6C:85:1B:BA:D0:03:63:07:4C:B1:89:D4:E6:B7:4E:CA:4A:23:C7:3C:5F:CA:3D
|
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，撸过没有签名的，可以用
|
puppet cert --sign node1.canghai.com
|
进行签发证书,签发后在master，执行
|
puppet cert list --all
|
即可看到证书已经签发
5.在服务端安装puppet的dashboard
安装mysql
|
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
|
cat /etc/my.cnf
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
max_allowed_packet = 32M
[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
|
启动服务
|
/etc/init.d/mysqld start
chkconfig mysqld on
|
设置mysql密码，我这里使用是密码是123456
|
mysqladmin -u root password &＃39;123456&＃39;
|
创建一个dashboard数据库
|
mysql -uroot -p123456 <
CREATE DATABASE dashboard CHARACTER SET utf8;
CREATE USER &＃39;dashboard&＃39;@&＃39;localhost&＃39; IDENTIFIED BY &＃39;123456&＃39;;
GRANT ALL PRIVILEGES ON dashboard.* TO &＃39;dashboard&＃39;@&＃39;localhost&＃39;;
FLUSH PRIVILEGES;
EOF
|
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
|
wget http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
rpm -ivh epel-release-6-8.noarch.rpm
yum install mod_passenger puppet-dashboard
|
配置Dashboard
|
vi /usr/share/puppet-dashboard/config/database.yml
production:
database: dashboard
username: dashboard
password: 123456
encoding: utf8
adapter: mysql
|
修改时区
|
vi /usr/share/puppet-dashboard/config/environment.rb
#config.time_zOne= &＃39;UTC&＃39;
config.time_zOne= &＃39;Beijing&＃39;
|
初始化数据库
|
cd /usr/share/puppet-dashboard/
rake RAILS_ENV=production db:migrate
|
配置Apache
我们需要整合Passenger和apache
|
cat > /etc/httpd/conf.d/passenger.conf <
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 master.canghai.com
DocumentRoot "/usr/share/puppet-dashboard/public/"
Options None
AllowOverride AuthConfig
Order allow,deny
allow from all
ErrorLog /var/log/httpd/master.canghai.com_error.log
LogLevel warn
CustomLog /var/log/httpd/master.canghai.com_access.log combined
ServerSignature On
EOF
|
启动服务
|
/etc/init.d/httpd start
chkconfig httpd on
|
配置puppet
让Dashboard使用Reports，现在默认agent是已经启用Report的功能，所以你就不需要设置agent,你只需要设置Server端就可以
|
vi /etc/puppet/puppet.conf
[master]
reports = store, http
reporturl = http://master.canghai.com:80/reports/upload
|
重启puppetmaster 服务
|
/etc/init.d/puppetmaster restart
|
这时候就可以直接用 http://ip 访问puppet Dashboard
导入报告
|
cd /usr/share/puppet-dashboard
rake RAILS_ENV=production reports:import
|
这时候你访问Dashboard,可以看到导入的任务.
4. 执行导入的reports
|
cd /usr/share/puppet-dashboard
rake jobs:work RAILS_ENV="production"
