使用Supervisor 托管netcore 和go服务

• 首先安装Supervisor 

  yum install epel-release
  yum install -y supervisor

• 新增supervisor 的配置

  #首先添加配置文件  vim /etc/supervisor/supervisord.conf
  ; 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 ".
  ;
  ; Warning:
  ;  Paths throughout this example file use /tmp because it is available on most
  ;  systems.  You will likely need to change these to locations more appropriate
  ;  for your system.  Some systems periodically delete older files in /tmp.
  ;  Notably, if the socket file defined in the [unix_http_server] section below
  ;  is deleted, supervisorctl will be unable to connect to supervisord.
  
  [unix_http_server]
  file=/tmp/supervisor.sock   ; the path to the socket file
  ;chmod=0700                 ; socket file mode (default 0700)
  ;chown=nobody:nogroup       ; socket file uid:gid owner
  ;username=user              ; default is no username (open server)
  ;password=123               ; default is no password (open server)
  
  ; Security Warning:
  ;  The inet HTTP server is not enabled by default.  The inet HTTP server is
  ;  enabled by uncommenting the [inet_http_server] section below.  The inet
  ;  HTTP server is intended for use within a trusted environment only.  It
  ;  should only be bound to localhost or only accessible from within an
  ;  isolated, trusted network.  The inet HTTP server does not support any
  ;  form of encryption.  The inet HTTP server does not use authentication
  ;  by default (see the username= and password= options to add authentication).
  ;  Never expose the inet HTTP server to the public internet.
  
  [inet_http_server]         ; inet (TCP) server disabled by default
  port=0.0.0.0:6001        ; ip_address:port specifier, *:port for all iface

• 配置netcore 服务

   #添加配置 vim /etc/supervisor/conf.d/loginservice.conf
  [program:LoginService]
  command=dotnet LoginService.dll  --urls "http://*:5002" ;
  directory=/usr/local/src/loginservice/ ;
  autorestart=true ;
  stderr_logfile=/var/log/LoginService.err.log ;
  stdout_logfile=/var/log/LoginService.out.log ;
  environment=ASPNETCORE_ENVIRONMENT=Production ;
  user=root ;
  stopsignal=INT

  command 为启动服务所需执行的命令  directory 为执行命令的文件夹。其他的见名知意。

• 配置go 服务

  #添加配置 vim /etc/supervisor/conf.d/BasicDataService.conf
  
  #/etc/supervisor/conf.d/basicservice.conf
  [program:BasicDataService]
  directory=/usr/local/src/goservice
  command=/usr/local/src/goservice/BasicDataService -conf /usr/local/src/goservice/configs/config.yaml
  stderr_logfile=/var/log/basicservice.err
  stdout_logfile=/var/log/basicservice.log
  autostart=true
  autorestart=true
  startsecs=10
  stdout_logfile_maxbytes=1MB
  stdout_logfile_backups=10
  stdout_capture_maxbytes=1MB
  stderr_logfile_maxbytes=1MB
  stderr_logfile_backups=10
  stderr_capture_maxbytes=1MB
  stopsignal=INT
  [supervisord] 

  command 添加了环境变量-conf 表示配置文件的目录

• 最终目录结构如下

   

   

• 手动启动supervisor 服务

   supervisord -c /etc/supervisor/supervisord.conf

• 最终启动成功如下

   

   

• 其他的一些常用命令

  supervisorctl stop all，停止全部进程，注：start、restart、stop都不会载入最新的配置文件。
  supervisorctl reload，载入最新的配置文件，停止原有进程并按新的配置启动、管理所有进程。
  supervisorctl update，根据最新的配置文件，启动新配置或有改动的进程，配置没有改动的进程不会受影响而重启。
  supervisorctl stop programxxx，停止某一个进程(programxxx)，programxxx为[program:chatdemon]里配置的值，这个示例就是chatdemon。
  supervisorctl start programxxx，启动某个进程
  supervisorctl restart programxxx，重启某个进程
