dh key too small

comment in /etc/ssl/openssl.conf

CipherString = DEFAULT@SECLEVEL=2

cert error Error: Could not request certificate: Error 400 on SERVER: The environment must be purely alphanumeric, not 'puppet-ca'

migrate from 3 to 5

具体请参考官方文档，3 to 5 官方文档 https://puppet.com/docs/puppet/5.5/upgrade_major_pre.html https://puppet.com/docs/puppet/5.5/upgrade_major_server.html

整个过程目前没想像的那么难受

install 5 repo

rpm -Uvh https://yum.puppet.com/puppet5/puppet5-release-el-7.noarch.rpm

yum -y install puppet-agent.x86_64

代码git的整个内容 放到/etc/puppetlabs/code/environments/production

Error: undefined method `index' for true:TrueClass

Error: /Stage[main]/Prometheus::Blackbox/Package[blackbox_exporter]/ensure: change from '0.21.0-1.el7' to true failed: undefined method `index' for true:TrueClass

表示ensure里面没有 puppet describe package找到ensure发现变了，没有true了

minds

<%= port > <% @port =>

file mode 0644 to '0644'

package ensure => 'latest' not true

Warning: /Stage[main]/Prometheus::Install/File[/etc/xxx]: Could not back up file of type directory

原因是文件夹里面有这个目录了，但是puppet不知道是否应该删除 add force => true to file declarations

Server Error: Syntax error at 'allow_virtual'
