如何在Azure池启动任务中运行多条命令？启动任务执行失败求助

It looks like your wget command is hitting a quoting/parsing issue in the Azure Batch start task environment—this is a common gotcha when passing multi-argument commands with nested quotes to shell environments. The error you're seeing (Usage: wget [OPTION]... [URL]...) means the shell is splitting your command incorrectly, so wget isn't receiving the parameters it expects.

Here's the corrected command to use: #

sudo bash -c 'wget --no-cookies --no-check-certificate --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie" http://download.oracle.com/otn-pub/java/jdk/8u161-b12/2f38c3b165be4555a1fa6e98c45e0808/jdk-8u161-linux-x64.rpm && yum localinstall jdk-8u161-linux-x64.rpm -y'

Why this works: #

• Wrapping the entire command chain in bash -c '' tells the shell to treat everything inside the single quotes as a single command string. This prevents the outer shell from misinterpreting the nested double quotes in your Cookie header.
• We removed the extra sudo before yum localinstall—since we're already running the entire command under sudo, it's redundant (and can cause unnecessary permission issues in some cases).

Additional checks: #

• Verify that the Azure Batch node has internet access to reach Oracle's download server.
• If you still hit issues, add verbose output to wget (-v flag) to get more detailed logs about what's going wrong:

  sudo bash -c 'wget -v --no-cookies --no-check-certificate --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie" http://download.oracle.com/otn-pub/java/jdk/8u161-b12/2f38c3b165be4555a1fa6e98c45e0808/jdk-8u161-linux-x64.rpm && yum localinstall jdk-8u161-linux-x64.rpm -y'
