Question

我遇到了在aws弹性beanstalk上全局安装pm2的问题。我创建了以下脚本来安装pm2：

option_settings:
  - option_name: NODE_ENV
    value: production
container_commands:
  01_enable_rootaccess:
    command: echo Defaults:root \!requiretty >> /etc/sudoers 
  02_install_imagemagic:
    command: yum install -y ImageMagick
  03_download_new_relic:
    command: rpm -Uvh http://download.newrelic.com/pub/newrelic/el5/i386/newrelic-repo-5-3.noarch.rpm 
    ignoreErrors: true
  04_install_new_relic:
    command: yum install -y newrelic-sysmond
    ignoreErrors: true
  05_add_license_key:
    command: /usr/sbin/nrsysmond-config --set license_key=xxxxxxx
    ignoreErrors: true
  06_start_new_relic:
    command: /etc/init.d/newrelic-sysmond start
    ignoreErrors: true
  07_install_pm2:
    command: sudo /opt/elasticbeanstalk/node-install/node-v0.10.26-linux-x64/bin/npm install pm2 -g
    ignoreErrors: true    
  08_stop_old_pm2_processes:
    command: sudo /opt/elasticbeanstalk/node-install/node-v0.10.26-linux-x64/bin/pm2 delete all
    ignoreErrors: true
  09_start_pm2:
    command: sudo /opt/elasticbeanstalk/node-install/node-v0.10.26-linux-x64/bin/pm2 startup -u ec2-user
    ignoreErrors: true

我尝试过只使用＆＃39; pm2删除全部＆＃39;和＆＃39; pm2启动＆＃39;对于命令8＆amp; 9把我刚刚找到命令找不到。当我给pm2的具体路径（我登录到ec2并验证）我得到＆＃34;第4行：exec ::找不到＆＃34;。知道我在这里做错了什么吗？在此先感谢您的帮助！

我设法在弹性beanstalk上全局安装pm2，并在.ebextensions / your_file_name.config文件中嵌入以下代码片段

container_commands:
  01_node_symlink:
    command: "ln -sf `ls -td /opt/elasticbeanstalk/node-install/node-* | head -1`/bin/node /bin/node"
  02_npm_symlink:
    command: "ln -sf `ls -td /opt/elasticbeanstalk/node-install/node-* | head -1`/bin/npm /bin/npm"
  03_pm2_install:
    command: "if [ ! -e /bin/pm2 ]; then npm install pm2 -g; fi"
    ignoreErrors: true

您可能需要确保已安装nodejs-legacy模块。如果pm2取决于名为node的可执行文件，那么当系统将其全局安装为nodejs时，如果某些Linux系统（Ubuntu，Debian）通常会这样做，则会失败。

npm global install on elastic beanstalk
