ubuntu18.04.04配置supervisord

使用root 用户

1.安装

pip3 install supervisor

2.复制supervisor.conf

mkdir /etc/supervisor

echo_supervisord_conf > /etc/supervisor/supervisord.conf

3.修改 配置文件

23行：file=/var/run/supervisor.sock

45行：logfile=/var/run/supervisord.log

49行： pidfile=/var/run/supervisord.pid 

75行：serverurl=unix:///var/run/supervisor.sock

169   [include]
170   files = /root/supervisor/conf.d/*.conf

4. 创建conf目录

mkdir -p  /root/supervisor/conf.d

5.示例 flask.conf

[program:micro_http]  ;程序名称
user=root  ;执行程序的用户
command=/usr/local/bin/gunicorn -w 4 -b 127.0.0.1:5000 flaskr:app --access-logfile=/var/log/micro-grid/server.log ;执行的命令
directory=/home/joker/soft/micro-grid/micro-grid-server ;命令执行的目录
stopsignal=TERM  ;重启时发送的信号
autostart=true
autorestart=true  ;是否自动重启
stdout_logfile=/var/log/micro-grid/stdout.log  ;标准输出日志位置
stderr_logfile=/var/log/micro-grid/stderr.log  ;标准错误日志位置

6.配置开机启动脚本

首行一定不能有空行，否则systemctl报错format error错误

7. chmod +x supervisord
