服務器版本 Ubuntu 16.04 LTS。
Supervisor 是一個用 Python 寫的進程管理工具,可以很方便的對進程進行啟動、停止、重啟等操作。
安裝命令:
$ apt-get install supervisor
安裝成功后,會在/etc/supervisor
目錄下,生成supervisord.conf
配置文件。
你也可以使用echo_supervisord_conf > supervisord.conf
命令,生成默認的配置文件(不建議,內容比較多)。
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
進程配置會讀取/etc/supervisor/conf.d
目錄下的*.conf
配置文件,我們在此目錄下創建一個hwapp.conf
進程配置文件:
[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
賬號,需要對這些目錄進行權限設置,要不然會報一些錯誤(一定要在 root 賬號下進行配置,要不然一系列權限引起的問題😂)。
$ sudo chmod 777 /var/run
$ sudo chmod 777 /etc/supervisor
接著就可以啟動 Supervisord 了:
$ supervisord
supervisorctl
常用命令:
命令 | 說明 |
---|---|
supervisorctl stop program_name | 停止某個進程 |
supervisorctl start program_name | 啟動某個進程 |
supervisorctl restart program_name | 重啟某個進程 |
supervisorctl stop all | 停止全部進程 |
supervisorctl reload | 載入最新的配置文件,停止原有進程并按新的配置啟動、管理所有進程 |
supervisorctl update | 根據最新的配置文件,啟動新配置或有改動的進程,配置沒有改動的進程不會受影響而重啟 |
