找不到Ansible内部脚本命令 [英] Ansible inside script command not found

问题描述

Ansible:

-   name: Node package manager
    npm:
        name: pm2
        global: yes
    notify:
        - restart nginx

-   name: start the app
    script: ../files/common/pm2.sh app_name {{ user }}
    tags: test

脚本文件:

#!/bin/bash
APP_NAME=$1
USER=$2

if [ "$USER" != "" ]; then
    PATH="/home/$USER/"
else
    PATH="/var/www/"
fi

pm2 describe ${APP_NAME} > /dev/null       # line no 11
RUNNING=$?

if [ "${RUNNING}" -ne 0 ]; then
  cd ${PATH}${APP_NAME}/ && pm2 start npm --name "${APP_NAME}" -- start
else
  pm2 restart ${APP_NAME}
fi;

当我尝试在远程计算机上运行 pm2 命令时，它正在工作.但是，不是从ansible脚本文件运行.

When I tried to run pm2 command on the remote machine, It's working. But, not running from ansible script file.

错误:

推荐答案

您正在覆盖脚本中的 PATH 环境变量.这用于确定可执行文件的位置(请参见 https://en.wikipedia.org/wiki/PATH_(变量)).

You're overwriting the PATH environment variable in your script. This is used to determine where executables are located (see https://en.wikipedia.org/wiki/PATH_(variable)).

简短的答案是为脚本中的 PATH 使用不同的名称，并对脚本中的命令使用绝对路径.

Short answer is to use a different name for PATH in your script and use absolute paths for commands in your script.
