Linux下安装Nginx

配置 yum 源

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

[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/7/$basearch/
gpgcheck=0
enabled=1

安装 Nginx

sudo yum install -y nginx

启动 Nginx 并设置开机自动运行

sudo systemctl start nginx.service
sudo systemctl enable nginx.service

配置根据域名进行代理

vi /etc/nginx/conf.d/xxx.conf

# 使用 80 端口，根据域名不同使用不同的接口代理
server {
    listen 80;
    server_name *.xxx.com;
    if ($http_host ~* "^(.*?)\.xxx\.com$") {
           set $domain $1;
    }

    location / {
        if ($domain ~* "aaa") {  #域名中有aaa，转发到8080端口
            proxy_pass http://0.0.0.0:8080;
        }
    }
    location / {
        if ($domain ~* "bbb") {  #域名中有bbb，转发到8090端口
            proxy_pass http://0.0.0.0:8090;
        }
    }
}

重启
