linux – 当master从命令行运行时,puppet master REST API在乘客工作时返回403

我正在使用puppet install中提供的标准auth.conf,用于通过Nginx下的乘客运行的puppet master.但是对于大多数目录,文件和证书请求,我得到403响应.

### Authenticated paths - these apply only when the client
### has a valid certificate and is thus authenticated

# allow nodes to retrieve their own catalog
path ~ ^/catalog/([^/]+)$
method find
allow $1

# allow nodes to retrieve their own node definition
path ~ ^/node/([^/]+)$
method find
allow $1

# allow all nodes to access the certificates services
path ~ ^/certificate_revocation_list/ca
method find 
allow *

# allow all nodes to store their reports
path /report
method save
allow *

# unconditionally allow access to all file services
# which means in practice that fileserver.conf will
# still be used
path /file
allow *

### Unauthenticated ACL,for clients for which the current master doesn't
### have a valid certificate; we allow authenticated users,too,because
### there isn't a great harm in letting that request through.

# allow access to the master CA
path /certificate/ca
auth any
method find
allow *

path /certificate/
auth any
method find
allow *

path /certificate_request
auth any
method find,save
allow *

path /facts
auth any
method find,search
allow *

# this one is not stricly necessary,but it has the merit
# of showing the default policy,which is deny everything else
path /
auth any

然而,当我在客户端上收到此错误时,Puppet master似乎没有跟随此

文件服务器配置文件如下(并按照他们在puppet站点上的说法进行操作,最好在auth.conf中调节访问以获取文件服务器,然后允许文件服务器到服务器全部)

我使用的是服务器和客户端版本3

Nginx已使用以下选项编译

nginx version: nginx/1.3.9
built by gcc 4.4.6 20120305 (Red Hat 4.4.6-4) (GCC) 
TLS SNI support enabled

和标准的nginx puppet master conf

Puppet正在从提到的文件中获取正确的设置,因为config print命令指向/ etc / puppet

[amisr1@bangvmpllDA02 puppet]$sudo puppet config print | grep conf
async_storeconfigs = false
authconfig = /etc/puppet/namespaceauth.conf
autosign = /etc/puppet/autosign.conf
catalog_cache_terminus = store_configs
confdir = /etc/puppet
config = /etc/puppet/puppet.conf
config_file_name = puppet.conf
config_version = ""
configprint = all
configtimeout = 120
dblocation = /var/lib/puppet/state/clientconfigs.sqlite3
deviceconfig = /etc/puppet/device.conf
fileserverconfig = /etc/puppet/fileserver.conf
genconfig = false
hiera_config = /etc/puppet/hiera.yaml
localconfig = /var/lib/puppet/state/localconfig
name = config
rest_authconfig = /etc/puppet/auth.conf
storeconfigs = true
storeconfigs_backend = puppetdb
tagmap = /etc/puppet/tagmail.conf
thin_storeconfigs = false

我检查了这个VM上的防火墙规则;允许80,443,8140,3000.我是否还需要调整auth.conf的任何细节才能使其正常工作？

更新

我在puppet master中添加了详细的日志记录并重新启动了nginx;这是我在日志中看到的其他信息

Mon Dec 10 18:19:15 +0530 2012 Puppet (err): Could not resolve 10.209.47.31: no name for 10.209.47.31

10.209.47.31 - - [10/Dec/2012:18:19:15 +0530] "GET /production/file_metadata/plugins? HTTP/1.1" 403 93 "-" "Ruby"

在代理机器上,facter fqdn和hostname都返回一个完全限定的主机名

[amisr1@blramisr195602 ~]$sudo facter fqdn
blramisr195602.XXXXXXX.com

然后,我更新了要添加的代理配置

dns_alt_names = 10.209.47.31

清除master和agent上的所有证书并重新生成证书,并使用选项–allow-dns-alt-names在master上签名

[amisr1@bangvmpllDA02 ~]$sudo puppet cert sign blramisr195602.XXXXXX.com

Error: CSR 'blramisr195602.XXXXXX.com' contains subject alternative names (DNS:10.209.47.31,DNS:blramisr195602.XXXXXX.com),which are 
disallowed. Use `puppet cert --allow-dns-alt-names sign blramisr195602.XXXXXX.com` to sign this request.

[amisr1@bangvmpllDA02 ~]$sudo puppet cert --allow-dns-alt-names sign blramisr195602.XXXXXX.com

Signed certificate request for blramisr195602.XXXXXX.com
Removing file Puppet::SSL::CertificateRequest blramisr195602.XXXXXX.com at '/var/lib/puppet/ssl/ca/requests/blramisr195602.XXXXXX.com.pem'

然而,这也无济于事;我和以前一样犯了同样的错误.不知道为什么在日志中它显示了按IP而不是主机名比较访问规则.是否有任何Nginx配置可以改变这种行为？

解决方法

我把它与我们在nginx上的另一个设置进行了比较;似乎问题是由于属性

ssl_client_header = SSL_CLIENT_S_D
ssl_client_verify_header = SSL_CLIENT_VERIFY

出现在master的puppet.conf中.从那里评论它们并在Nginx中保留它们的配置解决了问题.
