centos 安装 nginx 及配置 的坑

centos 安装 nginx 教程

1.创建/etc/yum.repos.d/nginx.

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

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

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

把里面的location 改成如下

location / {
proxy_pass http://localhost:5000; #把80端口的访问反向代理到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;
}
