Kong Gateway

    安装

    首先需要一个安装好的 postgreSQL 10+

    参考 https://docs.konghq.com/gateway/latest/install/linux/ubuntu

    1. 下载最新版 (3.2.1)

    wget https://jansora.oss-cn-shanghai.aliyuncs.com/lib/kong/kong_3.2.1_amd64.deb

    2. 安装

    sudo dpkg -i kong-3.2.1.amd64.deb

    可能会遇到依赖缺失的问题

    root@l2:~# dpkg -i kong_3.2.1_amd64.deb 
Selecting previously unselected package kong.
(Reading database ... 118922 files and directories currently installed.)

dpkg: dependency problems prevent configuration of kong:
 kong depends on zlib1g-dev; however:
  Package zlib1g-dev is not installed.

dpkg: error processing package kong (--install):
 dependency problems - leaving unconfigured

 kong

    3. 没关系, 执行下面的命令安装

    sudo apt-get -f install

    安装日志如下

    安装完之后再 /etc/kong/ 下能看到如下的文件

    root@l2:/etc/kong# tree /etc/kong
/etc/kong
├── kong.conf.default
└── kong.logrotate

0 directories, 2 files

    4. 调整配置文件

    cp /etc/kong/kong.conf.default /etc/kong/kong.conf

    主要调整数据库配置

    database = postgres
pg_host = l1.inet.jansora.com
pg_port = 55432
pg_user = kong
pg_password = ***
pg_database = kong

    如果端口有冲突, 也可调整端口

    By default, listens on the following ports:
    :8000: Port on which listens for incoming HTTP traffic from your clients, and forwards it to your upstream services.
    :8443: Port on which listens for incoming HTTPS traffic. This port has similar behavior as the :8000 port, except that it expects HTTPS traffic only. This port can be disabled with the kong.confconfiguration file.
    :8001: Port on which the Admin API used to configure listens.
    :8444: Port on which the Admin API listens for HTTPS traffic.

    5. 初始化数据库

    kong migrations bootstrap -c //etc/kong/kong.conf

    安装日志如下 (数据库配置正确)

    root@l2:/etc/kong#  kong migrations bootstrap -c /etc/kong/kong.conf
2023/03/14 23:20:14 [warn] ulimit is currently set to "1024". For better performance set it to at least "4096" using "ulimit -n"

    6. 启动 kong

    kong start -c /etc/kong/kong.conf

    7. 验证 kong 安装完毕

    curl -i http://localhost:8001

    输出配置信息
