.profile 未在厨师客户端上执行

Question

我的厨师服务器上有以下食谱：

# Insert the environment variables in .profile
execute "set-env-path" do
  command "echo 'export JAVA_HOME=/home/node/jdk1.6.0_45' >> /home/node/.profile && echo 'export PATH=$PATH:$JAVA_HOME/bin' >> /home/node/.profile"
end

# Execute .profile
execute "execute .profie" do
  command ". $HOME/.profile"
end 

当我在客户端上运行配方时，环境变量被插入到 .profile 中，但它们没有被设置。

为什么 .profile 文件没有在 chef 客户端上执行，为什么我的环境变量没有通过 chef 设置？

Answer 1

当 Chef 运行 execute 资源（包括 bash、script 等）时，它们在子 shell 中执行。您只是为该子 shell 设置环境，而不是 Chef Client 进程。如果需要设置环境变量，则需要使用 Ruby 块和 ENV 哈希：

ruby_block 'set environment' do
  block do
    ENV['MY_VARIABLE'] = 'MY_VALUE'
  end
end
