centos7.2 开发部署 .net core

1、centos7.2 安装 nginx
官方文档：http://nginx.org/en/linux_packages.html#mainline

创建nginx.repo 文件

Pre-Built Packages for Stable version

To set up the yum repository for RHEL/CentOS, create the file named /etc/yum.repos.d/nginx.repo with the following contents:

[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/OS/OSRELEASE/$basearch/
gpgcheck=0
enabled=1
Replace “OS” with “rhel” or “centos”, depending on the distribution used, and “OSRELEASE” with “5”, “6”, or “7”, for 5.x, 6.x, or 7.x versions, respectively.

执行以下命令：

vi /etc/yum.repos.d/nginx.repo

将下面内容复制到文件中，说明：我的系统是centos，版本是7.2,，不同的版本请根据上面的英文提示，进行替换
[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/7/$basearch/
gpgcheck=0
enabled=1

在同目录下创建nginx_signing.key文件

vi /etc/yum.repos.d/nginx_signing.key

将以下内容复制到文件中，保存

执行以下命令：
rpm --import nginx_signing.key

然后安装nginx

yum install nginx

输入：systemctl start nginx 来启动nginx。

输入：systemctl enable nginx 来设置nginx的开机启动（linux宕机、重启会自动运行nginx不需要连上去输入命令）。

命令：firewall-cmd --zone=public --add-port=80/tcp --permanent（开放80端口）

命令：systemctl restart firewalld（重启防火墙以使配置即时生效）

测试nginx是否可以访问。

http://192.168.1.41 (本机地址)

2、配置nginx对ASP.NET Core应用的转发
修改 /etc/nginx/conf.d/default.conf 文件。
将文件内容替换为(将192.168.1.41替换成自己的IP)：

upstream myserver {

server 192.168.1.41:5000;

}

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;
}
}

执行：nginx –s reload 使其即时生效

3、安装Supervisor

yum install python-setuptools

easy_install supervisor

4、配置Supervisor

mkdir /etc/supervisor

echo_supervisord_conf > /etc/supervisor/supervisord.conf

修改supervisord.conf文件，将文件尾部的配置

;[include]
;files = relative/directory/*.ini

替换为：

[include]
files = conf.d/*.conf

如果服务已启动，修改配置文件可用“supervisorctl reload”命令来使其生效

5、新建.net core web 测试程序

mkdir coreweb

cd coreweb

dotnet new -t web

6、配置对ASP.NET Core应用的守护

创建一个 coreweb.conf文件，内容大致如下

[program:coreweb]
command=dotnet run
directory=/root/coreweb/
autostart=true
autorestart=unexpected
startsecs=20
startretries=3
stderr_logfile=/var/log/coreweb.err.log
stdout_logfile=/var/log/coreweb.out.log
environment=ASPNETCORE_ENVIRONMENT=Production
;user=root;
stopsignal=INT

将文件拷贝至：/etc/supervisor/conf.d/coreweb.conf 下

运行supervisord，查看是否生效

supervisord -c /etc/supervisor/supervisord.conf

ps -ef | grep coreweb.dll

如果存在dotnet core.dll 进程则代表运行成功，这时候在使用浏览器进行访问。

至此关于ASP.NET Core应用程序的守护即配置完成。

7、配置Supervisor开机启动

新建一个“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

将文件拷贝至：“/usr/lib/systemd/system/supervisord.service”

执行命令：systemctl enable supervisord

执行命令：systemctl is-enabled supervisord #来验证是否为开机启动

Supervisord安装完成后有两个可用的命令行supervisor和supervisorctl，命令使用解释如下：

supervisord，初始启动Supervisord，启动、管理配置中设置的进程。
supervisorctl stop programxxx，停止某一个进程(programxxx)，programxxx为[program:blogdemon]里配置的值，这个示例就是blogdemon。
supervisorctl start programxxx，启动某个进程
supervisorctl restart programxxx，重启某个进程
supervisorctl stop all，停止全部进程，注：start、restart、stop都不会载入最新的配置文件。
supervisorctl reload，载入最新的配置文件，并按新的配置启动、管理所有进程。
