Ubuntu 安装和使用 Supervisor(进程管理)

服务器版本 Ubuntu 16.04 LTS。

Supervisor 是一个用 Python 写的进程管理工具,可以很方便的对进程进行启动、停止、重启等操作。

安装命令:

$ apt-get install supervisor

安装成功后,会在/etc/supervisor目录下,生成supervisord.conf配置文件。

你也可以使用echo_supervisord_conf > supervisord.conf命令,生成默认的配置文件(不建议,内容比较多)。

supervisord.conf示例配置:

; supervisor config file

[unix_http_server]
file=/var/run/supervisor.sock   ; (the path to the socket file)
chmod=0700                       ; sockef file mode (default 0700)

[supervisord]
logfile=/var/log/supervisor/supervisord.log ; (main log file;default $CWD/supervisord.log)
pidfile=/var/run/supervisord.pid ; (supervisord pidfile;default supervisord.pid)
childlogdir=/var/log/supervisor            ; ('AUTO' child log dir, default $TEMP)

; the below section must remain in the config file for RPC
; (supervisorctl/web interface) to work, additional interfaces may be
; added by defining them in separate rpcinterface: sections
[rpcinterface:supervisor]
supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface

[supervisorctl]
serverurl=unix:///var/run/supervisor.sock ; use a unix:// URL  for a unix socket

; The [include] section can just contain the "files" setting.  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 = /etc/supervisor/conf.d/*.conf

进程配置会读取/etc/supervisor/conf.d目录下的*.conf配置文件,我们在此目录下创建一个hwapp.conf进程配置文件:

[program:hwapp]
directory=/root/wwwroot/hwapp/publish
command=dotnet hwapp.dll
autostart=true
autorestart=true
startretries=10
redirect_stderr=true
stdout_logfile=/root/wwwroot/hwapp/hwapp.log
environment=ASPNETCORE_ENVIRONMENT="Development"

需要注意的是,如果不是root账号,需要对这些目录进行权限设置,要不然会报一些错误(一定要在 root 账号下进行配置,要不然一系列权限引起的问题😂)。

$ sudo chmod 777 /var/run
$ sudo chmod 777 /etc/supervisor

接着就可以启动 Supervisord 了:

$ supervisord

supervisorctl 常用命令:

命令 说明
supervisorctl stop program_name 停止某个进程
supervisorctl start program_name 启动某个进程
supervisorctl restart program_name 重启某个进程
supervisorctl stop all 停止全部进程
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
