原文:Ubuntu 安裝和使用 Supervisor(進程管理) - 田園里的蟋蟀 - 博客園 (cnblogs.com)
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
接着就可以啟動 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,停止原有進程並按新的配置啟動、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 |
