- 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.

[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/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
