Docker Nginx Supervisord
Ling的同事对于go服务的部署使用了k8s+安装supervisor的方案
所以我也要搞，只不过是阿里云 + docker
安装supervisor
apt update && apt install supervisor
* 要注意的是，docker直接pull的golang镜像启动后，没有vi、vim、nano，apt更新也超级慢（阿里云ECS）
* 所以要熟练手动换源，但是因为不能编辑(没试过gedit)，所以需要在容器-v的宿主机路径下添加换源后的sources.list
换源步骤
1.备份原来的源
sudo cp /etc/apt/sources.list /etc/apt/sources_init.list
将以前的源备份一下，以防以后可以用的。
2.更换源
sudo gedit /etc/apt/sources.list
使用gedit打开文档，将里面的内容清空，再将下边的阿里源复制进去，然后点击保存关闭。
阿里源(或者其他源)
deb http://mirrors.aliyun.com/ubuntu/ xenial main deb-src http://mirrors.aliyun.com/ubuntu/ xenial main deb http://mirrors.aliyun.com/ubuntu/ xenial-updates main deb-src http://mirrors.aliyun.com/ubuntu/ xenial-updates main deb http://mirrors.aliyun.com/ubuntu/ xenial universe deb-src http://mirrors.aliyun.com/ubuntu/ xenial universe deb http://mirrors.aliyun.com/ubuntu/ xenial-updates universe deb-src http://mirrors.aliyun.com/ubuntu/ xenial-updates universe deb http://mirrors.aliyun.com/ubuntu/ xenial-security main deb-src http://mirrors.aliyun.com/ubuntu/ xenial-security main deb http://mirrors.aliyun.com/ubuntu/ xenial-security universe deb-src http://mirrors.aliyun.com/ubuntu/ xenial-security universe
3.更新
sudo apt-get update
生成默认配置
echo_supervisord_conf > /etc/supervisor/conf.d/supervisord.conf
启动
如果报错
Unlinking stale socket /var/run/supervisor/supervisor.sock的话：
unlink /var/run/supervisor.sock
一般情况下直接搞就行了
supervisord -c /etc/supervisor/conf.d/supervisord.conf
nginx添加反代

[supervisord]
; Sample supervisor config file.
;
; For more information on the config file, please see:
; http://supervisord.org/configuration.html
;
; Notes:
; - Shell expansion ("~" or "$HOME") is not supported. Environment
; variables can be expanded using this syntax: "%(ENV_HOME)s".
; - Quotes around values are not supported, except in the case of
; the environment= options as shown below.
; - Comments must have a leading space: "a=b ;comment" not "a=b;comment".
; - Command will be truncated if it looks like a config file comment, e.g.
; "command=bash -c 'foo ; bar'" will truncate to "command=bash -c 'foo ".

切记修改文件权限
粗暴一点就好
chmod 777 /var/run/supervisor.sock
自带的supervisor管理界面
ip看实际情况而定
http://127.0.0.1:9001
supervisor的客户端部分命令
supervisorctl status 查看进程运行状态
supervisorctl start 进程名 启动进程
supervisorctl stop 进程名 关闭进程
supervisorctl restart 进程名 重启进程
supervisorctl update 重新载入配置文件
supervisorctl shutdown 关闭supervisord
supervisorctl clear 进程名 清空进程日志
supervisorctl 进入到交互模式下。使用help查看所有命令。
start stop restart + all 表示启动，关闭，重启所有进程。
