问题描述
创建新实例时,celery在该新实例中未运行,并且在将项目部署到EBS时,主管不会自动启动celery。用于在后台运行celery的“ supervisord.conf”文件:
; Sample supervisor config file. ; ; For more information on the config file,please see: ; http://supervisord.org/configuration.html ; ; Warning: ; Paths throughout this example file use /tmp because it is available on most ; systems.

“。ebextension / build.config”此文件包含的命令假定在完成部署后以超级用户身份运行
container_commands:
command1:
command: "test -f /usr/bin/google-chrome || wget https://dl.google.com/linux/direct/google-chrome-stable_current_x86_64.rpm"
command2:
command: "test -f /usr/bin/google-chrome || sudo yum -y install ./google-chrome-stable_current_x86_64.rpm"
command3:
command: "sudo cp -r /home/ec2-user/nltk_data /usr/share/nltk_data"
command4:
command: "test -f /usr/bin/supervisord || sudo amazon-linux-extras install -y epel"
command5:
command: "test -f /usr/bin/supervisord || sudo yum install -y supervisor"
command6:
command: "sudo unlink /tmp/supervisor.sock"
command7:
command: "sudo chown -R ec2-user:ec2-user /var/app/current"
command8:
command: "/usr/bin/supervisord -c /var/app/current/supervisord.conf"
cwd: "/var/app/current"
项目成功部署,但成功率不一致。
需要弄清楚我如何将项目“ eb部署”到aws之后如何使celery自动运行,并且在触发实例缩放后,celery应该在该新实例中自动运行。
解决方法
所以对于那些同样陷入这种情况的家伙。我放弃了使用超级用户的想法,而是在根目录中创建了一个“ Procfile”,并添加了celery命令(我将celery的绝对路径使用到我的venv位置)。两者都适用于worker并在部署时击败,“ systemd”将在后台运行芹菜,从而解决了在部署芹菜后运行芹菜的问题。到目前为止没有问题,我的网站运行良好。确保在celery命令中包括日志文件。
