最近研究kong，这里记录一下

1、说明

Nginx、OpenRestry、Kong这三个项目紧密相连：

Nginx是模块化设计的反向代理软件，C语言开发；
OpenResty是以Nginx为核心的Web开发平台，可以解析执行Lua脚本（OpenResty与Lua的关系，类似于Jvm与Java，不过Java可以做的事情太多了，OpenResty主要用来做Web、API等）；
Kong是一个OpenResty应用，是一个api gateway，具有API管理和请求代理的功能。

1.1 git地址

https://github.com/Kong/kong

1.2 kong安装说明

https://docs.konghq.com/install/source/

1.3 openssl

https://www.openssl.org/source/

2 下载lua-kong-nginx-module

https://github.com/Kong/lua-kong-nginx-module

3. 安装OpenResty

https://openresty.org/en/download.html

./configure \
—prefix=/home1/zcy/kong/openresty \
—with-pcre-jit \
—with-http_ssl_module \
—with-http_realip_module \
—with-http_stub_status_module \
—with-http_v2_module \
—with-openssl=/home1/zcy/kong/openssl-1.1.1c \
—add-module=/home1/zcy/kong/lua-kong-nginx-module

报错：you need to have ldconfig in your PATH env when enabling luajit

解决方法：编辑Makefile文件，将can_run(“ldconfig”)改成can_run(“/sbin/ldconfig”)

4 安装Luarocks

./configure \
—lua-suffix=jit \
—with-lua=/home1/zcy/kong/openresty/luajit \
—with-lua-include=/home1/zcy/kong/openresty/luajit/include/luajit-2.1 \
—prefix=/home1/zcy/kong/luarocks

配置环境：

export PATH=$PATH:/home1/zcy/kong/openresty/bin:/home1/zcy/kong/luarocks/bin:
export LUA_PATH=”/home1/zcy/kong/luarocks/share/lua/5.1/?.lua;;/home1/zcy/kong/luarocks/share/lua/5.1/?/init.lua;”

5. 安装kong

luarocks 安装：
$luarocks make kong-*.rockspec

$luarocks install kong 2.0.2-0

或者
$ git clone git@github.com:Kong/kong.git
$ cd kong
$ [sudo] make install # this simply runs the `luarocks make kong-*.rockspec` command

install成功

lua-resty-lrucache 0.09-2 is now installed in /home1/zcy/kong/luarocks (license: 2bsd)

lua-resty-acme 0.4.3-1 depends on lua-resty-openssl >= 0.2.1-1 (0.4.4-1 installed)
lua-resty-acme 0.4.3-1 is now installed in /home1/zcy/kong/luarocks (license: BSD)

kong-plugin-acme 0.2.2-1 is now installed in /home1/zcy/kong/luarocks (license: Apache 2.0)

kong 2.0.2-0 is now installed in /home1/zcy/kong/luarocks (license: Apache 2.0)

创建kong的数据库：

./bin/kong migrations up -c ./kong.conf

启动kong:

./bin/kong start -c ./kong.conf

kong默认的代理地址是：

proxy_listen = 0.0.0.0:8000, 0.0.0.0:8443

默认的管理地址是：

admin_listen = 127.0.0.1:8001, 127.0.0.1:8444 ssl

验证Kong

如果一切顺利，你应该看到一条消息通知你Kong正在运行。

默认情况下，Kong监听以下端口：

8000：监听来自Client的传入流量，并将其转发到上游服务
8443：与8000端口类似，它监听HTTPS流量
8001：Admin API用于配置Kong监听
8444：Admin API监听HTTPS流量

6. 报错解决

6.1 编译报错，缺少lyaml

You may have to install YAML in your system and/or pass YAML_DIR or YAML_LIBDIR to the luarocks command.
Example: luarocks install lyaml YAML_DIR=/usr/local
make: *** [install] Error 1

安装libyaml

# yum downgrade libyaml
# yum install libyaml-devel
