supervisord守护进程

安装

sudo apt-get install supervisor
echo_supervisord_conf
cat /etc/supervisord/supervisord.conf

检查 supervisord.conf 末行

[include]
files = /etc/supervisor/conf.d/*.conf
files = conf.d/*.conf

检查 supervisored.conf 末行

;[include] 
files = /etc/supervisor/*.conf

自定义文件.config

# environment             = PATH = "/root/.virtualenvs/cui_web/bin/"

尽量在目录下使用命令

开启服务

sudo supervisord -c supervisord.conf
若不在目录下
sudo supervisord -c /etc/supervisor/supervisord.conf
指定服务
sudo supervisorctl start 你的服务
>>! 正确结果
>>> $sudo supervisorctl -c supervisord.conf
>>> django_celery     RUNNING   pid 1398, uptime 0:00:00
>>> $supervisorctl  status
>>> django_celery     RUNNING   pid 2017, uptime 0:00:01

关闭服务

sudo ps -aux|grep super*
kill -9 xxx

服务常用指令

supervisorctl status        //查看所有进程的状态
supervisorctl stop es       //停止es
supervisorctl start es      //启动es
supervisorctl restart       //重启es
supervisorctl update        //配置文件修改后使用该命令加载新的配置
supervisorctl reload        //重新启动配置中的所有程序
