Ubuntu中通过SuperVisor添加守护进程
提示：扫一扫查出行【扫一扫了解最新限行尾号】
复制提示
1. 用途
守护进程用于保持一个指定程序（dll）时刻保持运行。在命令行终端中通过dotnet run命令执行的程序，在退出命令行终端后，程序自动终止。添加守护进程后，即使终端退出，程序仍可后台执行。可用于执行定时任务。
2. 安装（环境：ubuntu 16.04 dotnet 2.1.104）
sudo apt-get install supervisor （必须在root下执行）
3. 修改配置文件
配置文件路径：/ect/supervisor/conf.d/supervisord.conf
直接修改该文件
gedit supervisord.conf
增加：
1）开启查看进程的界面
[inet_http_server]
port=127.0.0.1:7002
2）添加被守护的程序
[program:TimeTest]
command=dotnet TimeTest.dll ;要执行的指令
directory=/mnt/hgfs/Projects/TimeTest/bin/Debug/netcoreapp2.0/publish ;dll的路径
autostart=true
autorestart=true
numprocs=1
process_name=TimeTests ;名称
3）重启
supervisorctl reload
4)访问localhost:7002（与配置文件中的端口相同）即可查看当前正在运行的所有程序
配置文件完整示例：
; supervisor config file
[unix_http_server]
file=/var/run/supervisor.sock ; (the path to the socket file)
chmod=0700 ; sockef file mode (default 0700)_
[inet_http_server]
port=127.0.0.1:7002
[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.
[program:TimeTest]
command=dotnet TimeTest.dll
directory=/mnt/hgfs/Projects/Linux/SurfaceRunoff/TimeTest/TimeTest/bin/Debug/netcoreapp2.0/publish
autostart=true
autorestart=true
numprocs=1
process_name=TimeTests
[include]
files = /etc/supervisor/conf.d/*.conf
