supervisord守護(hù)進(jìn)程

• 安裝

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

• 檢查 supervisord.conf 末行

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

• 檢查 supervisored.conf 末行

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

• 自定義文件.config

[program:django_celery]

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

directory               = /root/cui_web/zhizhi_kernel/  ; 命令所在目錄

command                 = /root/.virtualenvs/cui_web/bin/python manage.py celery worker -c 4 --loglevel= info

autorestart             = true          ; 是否自重啟

stdout_logfile_maxbytes = 20MB ；日志...
stderr_logfile_maxbytes = 20MB
stdout_logfile_backups  = 10
stderr_logfile_backups  = 10

stderr_logfile          = /root/cui_web/zhizhi_kernel/log/supervisor_err.log

loglevel                = info          ; 日志級別

盡量在目錄下使用命令

• 開啟服務(wù)

sudo supervisord -c supervisord.conf
若不在目錄下
sudo supervisord -c /etc/supervisor/supervisord.conf
指定服務(wù)
sudo supervisorctl start 你的服務(wù)
>>! 正確結(jié)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

• 關(guān)閉服務(wù)

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

• 服務(wù)常用指令

supervisorctl status        //查看所有進(jìn)程的狀態(tài)
supervisorctl stop es       //停止es
supervisorctl start es      //啟動es
supervisorctl restart       //重啟es
supervisorctl update        //配置文件修改后使用該命令加載新的配置
supervisorctl reload        //重新啟動配置中的所有程序
