大厨：在配方中搜索节点 returns 错误 500。
Chef: searching node inside recipe returns error 500.
我也在使用 Chef 11（开源服务器）和 chef-client 11。我正在尝试搜索具有特定角色的节点。使用 knife 我可以获得我希望使用的结果：
knife search node "run_list:role\[cassandra\]"。我也可以在食谱中使用 search(:node, "run_list:role\[cassandra\]") 进行搜索。但是，如果我尝试使用属性访问该角色，我将无法使其正常工作。我已经尝试了最明显的方法 search(:node, "run_list:role\[#{node[:role][:cassandra]}\]") 并尝试在搜索行之外编写查询 (query = 'run_list:role\[' + node[:cassandra][:seed_role]) 但我得到了同样的错误。我在 Chef-client 编译阶段收到错误 500（我认为）。这是我使用的部分代码和输出日志。
# Searching for Cassandra nodes inside the same Chef environment
cassandra_seeds = []
cassandra_nodes_macs = []
query = 'run_list:role\[' + node[:cassandra][:seed_role] + '\] AND chef_environment:#{node.chef_environment}'
log query
search(:node, query).each do |n|
# search(:node, "run_list:role\[cassandra\] AND \
# chef_environment:#{node.chef_environment}").each do |n|
# search(:node, "roles:*#{node[:cassandra][:seed_role]} AND \
# chef_environment:#{node.chef_environment}").each do |n|
cassandra_seeds << n[:fqdn] unless n[:fqdn] == node[:fqdn]

发表评论后我和 chef-shell 一起玩（尝试在与菜谱相同的上下文中搜索）
我发现有效的语法（角色名称周围没有引号）：
search(:node, 'run_list:role\[mysql-server-wso2\] AND chef_environment:I1')search(:node, "run_list:role\[mysql-server-wso2\] AND chef_environment:I1")
双引号方式听起来最适合变量插值。
以您的案例为例：
query = "run_list:role\[#{node[:cassandra][:seed_role]}\] AND chef_environment:#{node.chef_environment}"
您可以通过在后面添加一条日志行来确保它被正确插入：
Chef::Log.info "Query is: #{query}"
旧答案：
我不知道你为什么用单引号将它设置为单引号，但这可能是你的问题：
query = 'run_list:role\[' + node[:cassandra][:seed_role] + '\] AND chef_environment:#{node.chef_environment}'
在单引号中，#{node.chef_environment} 未被替换并按原样发送到 Chef 服务器，服务器无法正确解析并因 500 错误而失败。
这样写查询应该没问题：
query = "run_list:role['#{node[:cassandra][:seed_role]}'] AND chef_environment:#{node.chef_environment}"
