Question

Ansible 1.9.2 / latest。操作系统：CentOS 6.7 /更高版本 JAVA_HOME，PATH变量和所有其他东西都设置正确。

我在perf_tests / tasks / main.yml中运行了以下playbook。要仅运行此剧本，我使用Ansible标签。

# Run JMeter tests
- name: Run JMeter test(s)
#  command: "export PATH={{ jdk_install_dir }}/bin:$PATH && export JAVA_HOME={{ jdk_install_dir }} && {{ jmeter_install_dir }}/bin/jmeter -n -t {{ common_download_dir}}/perf_tests/ProjectTest1.jmx -l {{ common_download_dir}}/perf_tests/log_jmeter_ProjectTest1.jtl"
  command: export PATH={{ jdk_install_dir }}/bin:$PATH && export JAVA_HOME={{ jdk_install_dir }} && /apps/jmeter/apache-jmeter-2.13/bin/jmeter -n -t /tmp/perf_tests/ProjectTest1.jmx -l /tmp/perf_tests/log_jmeter_ProjectTest1.jtl
  become_user: "{{ common_user }}"
  tags:
     - giga

JMeter可执行文件所需的文件存在于目标计算机上，我使用＆＃34;命令＆＃34;在ansible模块中启动JMeter。

[appuser@jmeter01 ~]$ ls -l /apps/jmeter/apache-jmeter-2.13/bin/jmeter /tmp/perf_tests/ProjectTest1.jmx
-rwxr-xr-x. 1 appuser appgroup  5589 Mar  8  2015 /apps/jmeter/apache-jmeter-2.13/bin/jmeter
-rw-r--r--. 1 appuser appgroup 50194 Oct  2 12:19 /tmp/perf_tests/ProjectTest1.jmx
[appuser@jmeter01 ~]$

[appuser@jmeter01 ~]$ which java
/apps/jdk/jdk1.7.0_67/bin/java

当我运行上面的playbook时，在.jmx文件上运行jmeter来生成一个结果.jtl文件（使用ANSIBLE），它的错误输出错误代码为2（如下所示）： msg：[Errno 2]没有这样的文件或目录

ANSIBLE输出：

上面的ansible＆＃t; svvv详细输出中的＆＃34; cmd＆＃34; 显示，Ansible成功通过/扩展了所有内容，用于调用jmeter命令，但它＆＃39失败了。

IF 我转到远程机器（jmeter01）和＆＃34; appuser＆＃34;并运行该命令，它工作正常，并成功创建提供.jtl结果文件的-l选项。

[appuser@jmeter01 ~]$ /apps/jmeter/apache-jmeter-2.13/bin/jmeter -n -t /tmp/perf_tests/ProjectTest1.jmx -l /tmp/perf_tests/log_jmeter_ProjectTest1.jtl

我难以理解为什么JMeter在使用Ansible运行时出错了这个错误！？

Answer 1

您不能将export或&&与command模块一起使用，因为它直接执行命令，而不是通过shell，而export是一个shell内置。

您需要shell模块。

比较输出：

ansible myserver -m command -a "echo Hello && echo Goodbye"
ansible myserver -m command -a "export GREET=Hello && echo '$GREET'"

ansible myserver -m shell -a "echo Hello && echo Goodbye"
ansible myserver -m shell -a "export GREET=Hello && echo '$GREET'"

你可以清楚地看到这一点。

Answer 2

Seumasmac是对的。我无法找到任何地方＆＃34;命令＆＃34;模块能够运行jmeter来运行测试（我甚至尝试硬编码值并将其传递给命令：xxx xxx xxx）。

使用以下＆＃34; shell ＆＃34;模块我能够运行多个.jmx（如果项目有）并且还获取（将结果.jtl文件返回到运行ansible的源服务器）。

使用＆＃34; with_items＆＃34;，我可以传递jmxfile值并获得多个jmeter运行。脚本：run_jmeter_test.sh捆绑在一个ZIP文件中，我在{{common_download_dir}} == / tmp中首先（使用复制模块）推送到目标/远程jmeter01服务器并且我能够创建perf_tests文件夹并在那里解压缩ZIP以在运行playbook之前完成所有设置以运行JMeter可执行文件/命令。

# Run JMeter tests using Ansible shell module on remote Jmeter node
- name: Run JMeter tests using Ansible shell module on remote Jmeter node and pass parameters
  shell: "sudo {{ common_download_dir }}/perf_tests/run_jmeter_test.sh {{ jdk_install_dir }} {{ jmeter_install_dir }}/bin/jmeter {{ common_download_dir }}/perf_tests/{{ item.jmxfile }}.jmx {{ common_download_dir }}/perf_tests/log_jmeter_{{ item.jmxfile }}.jtl"
  become_user: "{{ common_user }}"
  with_items:
    - { jmxfile: 'ProjectTest1' }
#    - { jmxfile: 'ProjectTest101' }
#    - { jmxfile: 'ProjectTest102' }

# Fetch JMeter test(s) result .jtl file(s) from remote server and put it in local workspace.
- name: Fetch JMeter test(s) result .jtl file(s)
  fetch: src="{{ common_download_dir}}/perf_tests/log_jmeter_{{ item.jmxfile }}.jtl" dest="perf_tests/{{ item.jmxfile}}.jtl" flat=yes fail_on_missing=yes
  with_items:
    - { jmxfile: 'ProjectTest1' }
#    - { jmxfile: 'ProjectTest101' }
#    - { jmxfile: 'ProjectTest102' }

run_jmeter_test.sh 看起来像（非常简单/简单版本）：

#!/bin/sh

javaHome=$1
jmExec=$2
jmxFile=$3
jtlFile=$4

export PATH=$javaHome/bin:$PATH

$jmExec -n -t $jmxFile -l $jtlFile

我的其他帖子还展示了我如何获得JMeter可执行文件以及它的Extra / Standard / WebDriver插件。

ansible命令模块：JMeter msg：[Errno 2]没有这样的文件或目录
