ASP.NET CORE部署到CentOS中
- 在Linux上安装.NET Core
- 配置Nginx
-
安装前准备
yum install gcc-c++
yum install pcre pcre-devel
yum install zlib zlib-devel
yum install openssl openssl--devel -
下载安装Nginx,执行如下命令
-
解压
tar -zxvf nginx-1.11.13.tar.gz
-
进入解压目录
cd nginx-1.11.13
-
配置
./configure --prefix=/usr/local/nginx
- 注意:这里可能会报错,提示“pcre.h No such file or directory”,需要安装
libprce3-dev:sudo apt-get install libpcre3-dev 注意:提示“./configure: error: C compiler cc is not found”,需要检查是否安转了
常用必备支持库,如没有,需要安装g++,gcc:yum install gcc-c++-
安装nginx
make
make install - systemctl start nginx 来启动nginx
systemctl enable nginx 来设置nginx的开机启动
-
配置防火墙
firewall-cmd --zone=public --add-port=80/tcp --permanent(开放80端口)
systemctl restart firewalld(重启防火墙以使配置即时生效)
systemctl stop firewalld.service(关闭防火墙)
systemctl disable firewalld.service(关闭开机启动) - 配置ASP.NET Core应用的转发
-
修改 /etc/nginx/conf.d/default.conf 文件
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;
}
}
nginx –s reload 使其即时生效 -
若出现502错误;这个问题是由于SELinux保护机制所导致,我们需要将nginx添加至SELinux的白名单。
yum install policycoreutils-python
cat /var/log/audit/audit.log | grep nginx | grep denied | audit2allow -M mynginx
semodule -i mynginx.pp
- 配置守护服务(Supervisor)
-
安装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,将文件尾部配置改为
[include]
files=conf.d/*.conf 修改配置文件可用 supervisorctl reload 命令使其生效
- 配置ASP.NET Core应用的守护
-
创建一个WebDemo.conf文件,内容如下
[program:WebDemo]
command=dotnet WebDemo.dll (运行程序的命令)
directory=/root/code/WebDemo/ (命令执行的目录)
autorestart=true (程序意外退出是否自动重启)
stderr_logfile=/var/log/WebDemo.err.log (错误日志文件)
stdout_logfile=/var/log/WebDemo.out.log (输出日志文件)
environment=ASPNETCORE_ENVIRONMENT=Production (进程环境变量)
user=root (进程执行的用户身份)
stopsignal=INT 将文件拷贝至:“/etc/supervisor/conf.d/”目录下
-
运行supervisord查看是否生效
supervisord -c /etc/supervisor/supervisord.conf
ps -ef | grep WebDemo - 可能出现的问题
- 运行supervisord -c /etc/supervisor/supervisord.conf报错
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.
-
解决办法
ps -ef |grep supervisord
kill -s SIGTERM 2503
- 配置Supervisor开机启动
-
新建一个supervisord.service文件
[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/”目录下
systemctl enable supervisord
systemctl is-enabled supervisord 验证是否为开机启动
