netcore应用程序部署程序到ubuntu

运维需求：获取服务器的运行情况，是否CPU、内存较高等，上报到运维系统

环境：ubuntu16.04

工具:：netcore2.1、supervisor

程序实现（代码就不贴了）参考：https://blog.csdn.net/u014518337/article/details/86291984

因需要获取系统数据，部分命令行不支持在docker环境运行，因此直接由dotnet直接运行程序，守护进程由supervisor 守护

1、安装netcore2.1

wget -q https://packages.microsoft.com/config/ubuntu/16.04/packages-microsoft-prod.deb
sudo dpkg -i packages-microsoft-prod.deb
sudo apt-get install apt-transport-https
sudo apt-get update
sudo apt-get install dotnet-sdk-2.1

执行 dotnet --info  查看是否安装正确

2、安装supervisor

参考：https://www.cnblogs.com/savorboard/p/dotnetcore-supervisor.html

sudo apt-get install supervisor

安装完成之后，在 /ect/supervisor/conf.d/ 目录下新建一个配置文件（touch HelloWebApp.conf），取名为 HelloWebApp.conf

打开HelloWebApp.conf （vim HelloWebApp.conf），写入如下命令：

[program:HelloWebApp]
command=dotnet HelloWebApp.dll  #要执行的命令
directory=/home/xxx/publish #命令执行的目录
environment=ASPNETCORE__ENVIRONMENT=Production #环境变量
user=www-data  #进程执行的用户身份
stopsignal=INT
autostart=true #是否自动启动
autorestart=true #是否自动重启
startsecs= #自动重启间隔
stderr_logfile=/var/log/HelloWebApp.err.log #标准错误日志
stdout_logfile=/var/log/HelloWebApp.out.log #标准输出日志

注意：上面代码需要把注释 #后面的中文删掉

修改配置文件/etc/supervisor/supervisord.conf  添加supervisord web管理功能  红色为新增配置部分

;upervisor config file

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

[inet_http_server]
port=*:9001
username=user
password=123

[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

保存之后重启下程序

sudo supervisorctl shutdown && sudo supervisord -c /etc/supervisor/supervisord.conf

如果启动异常根据提示查看配置修改配置文件
