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.

This; setting can List multiple files (separated by whitespace or; newlines).  It can also contain wildcards.  The filenames are; interpreted as relative to this file.  Included files *cannot*; include files themselves.[include]files = conf.d/*.conf

[include] 表示 导入conf.d下面的所有配置文件

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/goservicecommand=/usr/local/src/goservice/BasicdataService -conf /usr/local/src/goservice/configs/config.yamlstderr_logfile=/var/log/basicservice.errstdout_logfile=/var/log/basicservice.logautostart=trueautorestart=truestartsecs=10stdout_logfile_maxbytes=1MBstdout_logfile_backups=10stdout_capture_maxbytes=1MBstderr_logfile_maxbytes=1MBstderr_logfile_backups=10stderr_capture_maxbytes=1MBstopsignal=INT[supervisord] 

command 添加了环境变量-conf 表示配置文件的目录

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
