1、Nginx的安裝(重啟Nginx命令: systemctl restart nginx)

輸入命令(?根據提示輸入Y 即可):?

? ? ? ? ? sudo yum install epel-release?

? ? ? ? ? sudo yum install nginx

? ? ? ? ??sudo systemctl start nginx

?還需要輸入關閉防火墻命令:

? ? ? ? ?sudo firewall-cmd --permanent --zone=public --add-service=http

?　 　sudo firewall-cmd --permanent --zone=public --add-service=https

?　 　sudo firewall-cmd --reload

配置防火墻
命令：firewall-cmd --zone=public --add-port=80/tcp --permanent（開放80端口）
命令：systemctl restart firewalld（重啟防火墻以使配置即時生效）

完成之后可以在Windows的瀏覽器中輸入上面的IP訪問了

2、如果輸入dotnet CoreDemo.dll出現報錯,運行命令: sudo yum install dotnet-sdk-2.1.3切換版本

在CentOS中使用命令: curl http://localhost:5000沒有出現錯誤則成功

?

3、修改Nginx配置來實現局域網訪問

進入/etc/nginx/ 修改其中的nginx.conf文件

將其中的server段替換成下面的配置

server {
listen 80;
? 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;
?}
}

最后使用命令:?systemctl restart nginx?重啟Nginx

輸入之后發現出現502 Bad GateWay.....

這個問題發現是因為Linux保護機制所導致，我們需要將nginx添加至Linux的白名單

輸入以下命令:

yum install policycoreutils-python

sudo cat /var/log/audit/audit.log | grep nginx | grep denied | audit2allow -M mynginx

sudo semodule -i mynginx.pp

再嘗試訪問

4、配置將Nginx改為自啟動:

使用命令:?systemctl enable nginx.service 或者?systemctl enable nginx

使用命令:?systemctl is-enabled nginx?來確認是否設置成功

5、配置守護服務（Supervisor）

我們需要有一個程序來監聽ASP.NET Core 應用程序的狀況。在應用程序停止運行的時候立即重新啟動。這邊我們用到了Supervisor這個工具，Supervisor使用Python開發的。

安裝Supervisor
yum install python-setuptools

easy_install supervisor

配置Supervisor
mkdir /etc/supervisor

echo_supervisord_conf > /etc/supervisor/supervisord.conf

修改supervisord.conf文件，將文件尾部的配置

修改為

修改配置文件可用“supervisorctl reload”命令來使其生效

遇到的錯誤

* Starting Supervisor daemon manager...
Error: Another program is already listening on a port that one of our HTTP servers is configured to use. Shut this program down first before starting supervisord.
For help, use /usr/bin/supervisord -h
...fail!

解決辦法

find / -name supervisor.sock
unlink /***/supervisor.sock

6、配置對ASP.NET Core應用的守護

創建一個 Core.Web.conf文件，內容大致如下

[program:Core.Web]
command=dotnet Core.Web.dll ;
directory=/home/netcore/ ; #發布目錄 ;
autorestart=true ;
autostart=true ;
stderr_logfile=/var/log/core.web.err.log ;
stdout_logfile=/var/log/core.web.out.log ;
environment=ASPNETCORE_ENVIRONMENT=Production ;
user=root ;
stopsignal=INT ;
startsecs=1 ;

將文件拷貝至：“/etc/supervisor/conf.d/Core.Web.conf”下

運行supervisord，查看是否生效

[root@bogon ~]# supervisord -c /etc/supervisor/supervisord.conf
Error: Another program is already listening on a port that one of our HTTP servers is configured to use. Shut this program down first before starting supervisord.
For help, use /usr/bin/supervisord -h
[root@bogon ~]# find / -name supervisor.sock
/tmp/supervisor.sock
[root@bogon ~]# unlink /***/supervisor.sock
[root@bogon ~]# supervisord -c /etc/supervisor/supervisord.conf
[root@bogon ~]# ps -ef | grep Core.Web
root 24817 1296 0 11:07 pts/0 00:00:02 dotnet Core.Web.dll
root 35113 24513 0 11:40 pts/1 00:00:00 grep --color=auto Core.Web

?

7、配置Supervisor開機啟動

新建一個“supervisord.service”文件

# dservice for systemd (CentOS 7.0+)
# by ET-CS (https://github.com/ET-CS)
[Unit]
Description=Supervisor daemon

[Service]
Type=forking
ExecStart=/usr/bin/supervisord -c /etc/supervisor/supervisord.conf
ExecStop=/usr/bin/supervisorctl shutdown
ExecReload=/usr/bin/supervisorctl reload
KillMode=process
Restart=on-failure
RestartSec=42s

[Install]
WantedBy=multi-user.target

將文件拷貝至：“/usr/lib/systemd/system/supervisord.service”

執行命令：systemctl enable supervisord

[root@bogon ~]# systemctl enable supervisord
Created symlink from /etc/systemd/system/multi-user.target.wants/supervisord.service to /usr/lib/systemd/system/supervisord.service.

執行命令：systemctl is-enabled supervisord #來驗證是否為開機啟動
[root@bogon ~]# systemctl is-enabled supervisord
enabled
