centos 安装 nginx 教程

1.创建/etc/yum.repos.d/nginx.repo

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

2.编辑
sudo vim /etc/yum.repos.d/nginx.repo

[nginx-stable]
name=nginx stable repo
baseurl=http://nginx.org/packages/centos/7/$basearch/
gpgcheck=1
enabled=1
gpgkey=https://nginx.org/keys/nginx_signing.key

[nginx-mainline]
name=nginx mainline repo
baseurl=http://nginx.org/packages/mainline/centos/7/$basearch/
gpgcheck=1
enabled=0
gpgkey=https://nginx.org/keys/nginx_signing.key

3.以上配置完后，执行命令查看nginx源

yum list|grep nginx
yum repolist
会看到nginx源信
4.执行安装

sudo yum -y install nginx

nginx -v查看是否安装成功

5.配置nginx
sudo vim /etc/nginx/conf.d/default.conf

把里面的location 改成如下

location / {
proxy_pass https://localhosts:5001; #asp.net core 程序默认会强制重定向使用https,所以不要绑定http://localhosts:5000端口
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection keep-alive;
proxy_set_header Host $http_host;
proxy_cache_bypass $http_upgrade;
}

检查nginx配置是否正确： sudo nginx -t

启动nginx，先进入目录
cd /usr/sbin
sudo ./nginx

6.使用下列命令来重新加载配置。
sudo nginx -s reload

sudo chown -R ec2-user:ec2-user /usr/sbin/nginx

======防火墙管理=================================
sudo yum install firewalld

firewalld的基本使用

启动：sudo systemctl start firewalld

关闭： sudo systemctl stop firewalld

查看状态： sudo systemctl status firewalld

开机禁用： sudo systemctl disable firewalld

开机启用：sudo systemctl enable firewalld
————————————————

sudo firewall-cmd --query-port=80/tcp 验证80端口是否打开

开启80端口

sudo firewall-cmd --add-port=80/tcp --permanent
#重启防火墙
sudo systemctl restart firewalld

--permanent #永久生效，没有此参数重启后失效
