诚邀

邀请共建前端

简介

作者:京城郭少

openfly是基于nginx的4层代理管理平台,数据存储于etcd。

有任何问题,欢迎提issue。

支持的功能:

  • 负载均衡
  • 被动健康检查
  • 白名单
  • include导入文件
  • 哈希
  • backup冗余互备
  • weight权重
  • 注释
  • 限速
  • 超时控制
  • 启用/禁用
  • ......

部署openfly

部署nginx:

  • 目标:部署一个支持stream模块的nginx。
  • 步骤仅供参考,可自行发挥。
systemctl stop firewalld
systemctl disable firewalld
setenforce 0
sed -i '/^SELINUX=/cSELINUX=disabled' /etc/selinux/config
yum install -y gc gcc gcc-c++ pcre-devel zlib-devel openssl-devel libxslt-devel GeoIP-devel perl-ExtUtils-Embed make
wget http://nginx.org/download/nginx-1.24.0.tar.gz
tar -xvf nginx-1.24.0.tar.gz
cd nginx-1.24.0/
mkdir -p /usr/local/nginx
# 关键在于--with-stream=dynamic --with-stream_ssl_module

    [Install]
    WantedBy=multi-user.target
systemctl daemon-reload
systemctl restart nginx
systemctl enable nginx

配置nginx:

  • 目标:启用nginx的4层代理功能
mkdir -p /etc/nginx/stream.d
vim /etc/nginx/nginx.conf
    load_module /usr/local/nginx/modules/ngx_stream_module.so;      # 此配置放在文件的首行
    ......
    stream {
        include /etc/nginx/stream.d/*.conf;   # 此目录交给openfly托管
    }
nginx -t
nginx -s reload

部署etcd:

yum install -y etcd
vim /etc/etcd/etcd.conf
    ETCD_LISTEN_CLIENT_URLS="http://0.0.0.0:2379"
systemctl enable --now etcd
vim /etc/bashrc
    export ETCDCTL_API=3
source /etc/bashrc

启动openfly

# 会生成data目录,里面都是nginx的4层代理配置文件,nginx需要导入这个目录:include xxx/data/*.conf;
vim config-vx.x.x.toml                  # 编辑配置文件
./openfly-vx.x.x -c config-vx.x.x.toml  # 启动openfly
# 将openfly生成的nginx配置,软链到nginx配置目录中
ln -s ./data /etc/nginx/stream.d/

Demo:添加一个nginx配置

token=$(curl -s -XPOST http://127.0.0.1:1216/v1/login -d "{\"username\":\"admin\",\"password\":\"admin\"}" -H "Content-Type: application/json" | jq -r .data)
curl -i -H "Content-Type: application/json" -XPOST -H "Authorization: ${token}" http://127.0.0.1:1216/v1/admin/nginx/add -d '
{
    "listen":30001,
    "upstream":{
        "hosts":[
            {
                "ip":"1.1.1.1",
                "port":53
            }
        ]
    }
}'
