openSUSE 42.2+ x64
SUSE Enterprise Linux (SLES) 12 SP2+ x64

实验用到的环境

aliyun centos 7.3 64位

安装.net core 2.0 依赖的组件

deltarpm
epel-release
unzip
libunwind
gettext
libcurl-devel
openssl-devel
zlib
libicu-devel

直接yum安装这些组件

yum install deltarpm epel-release unzip libunwind gettext libcurl-devel openssl-devel zlib libicu-devel

安装.net core 2.0

sudo dnf install libunwind libicu
curl -sSL -o dotnet.tar.gz https://aka.ms/dotnet-sdk-2.0.0-linux-x64
sudo mkdir -p /opt/dotnet && sudo tar zxf dotnet.tar.gz -C /opt/dotnet
sudo ln -s /opt/dotnet/dotnet /usr/local/bin
dotnet --help

在命令 dotnet --help 看到下面信息就安装.net core 2.0成功了

使用VS2017.3 新建一个.net core 2.0 的测试代码

可以从此地址下载：https://files.cnblogs.com/files/fun5/webcore.zip

使用xftp 把生成好的程序（webcorewebcoreinDebug etcoreapp2.0publish下的文件）上传到 /home/test 目录下

执行命令

cd /home/test
dotnet webcore.dll &

可以看到已经运行起来了，localhost:5000

安装配置nginx

yum install nginx

配置nginx.conf

    server {

		listen 80;
        server_name  test.fun5.cn;

		location / {
			proxy_pass http://localhost:5000;
			proxy_http_version 1.1;
			proxy_set_header Upgrade $http_upgrade;
			proxy_set_header Connection keep-alive;
			proxy_set_header Host $host;
			proxy_cache_bypass $http_upgrade;
		}

        error_page 404 /404.html;
            location = /40x.html {
        }

        error_page 500 502 503 504 /50x.html;
            location = /50x.html {
        }
    }

执行 nginx -s reload

访问 nginx 绑定的域名可以看到网站可以跑起来了 http://test.fun5.cn/

配置守护进程

安装Supervisor

yum install supervisor

Supervisor配置文件，创建一个ini 配置文件 webcore.ini

[program:webcore]
command=dotnet webcore.dll
directory=/home/test 
environment=ASPNETCORE__ENVIRONMENT=Production 
user=root
stopsignal=INT
autostart=true
autorestart=true
startsecs=3 
stderr_logfile=/var/log/webcore.err.log  
stdout_logfile=/var/log/webcore.out.log

创建好之后，使用 xftp 上次到 /etc/supervisord.d 目录下

最后启动

supervisord  -c /etc/supervisord.conf

如果想要supervisord开机自启动

# 编辑启动文件
vi /etc/rc.local
# 在新行添加要执行的命令
supervisord -c /etc/supervisord.conf
常用命令
# 查看所有action
supervisorctl help

# 控制所有进程
supervisorctl start all
supervisorctl stop all
supervisorctl restart all

# 控制目标进程
supervisorctl stop shadowsocks
supervisorctl start shadowsocks
supervisorctl restart shadowsocks

结束！
