Kong source code installation

Keywords: Programming OpenSSL SSL yum zlib

;

Kong is a cloud-native, fast, scalable, and distributed Microservice API Gateway

background

Although Kong has reached 2.0, because the previous expansion development was based on Kong 1.2.1, the source code and development environment construction of Kong are based on Version 1.2.1. The subsequent versions can follow this process, but the versions of each component are different.

Dependent version

0. kong's extension based on 1.2.1

1. openresty 1.13.6.2

2. luarocks 2.4.3

 

Installation dependency

ibyaml-devel.x86_64

Install yaml package ` Yum install libyaml-devel.x86 ʄ`

If there is no yaml package, an error will be reported when executing ` / data / APP / lualocks / bin / lualocks make ` compile kong:

Error: Failed installing dependency: https://luarocks.org/lyaml-6.2.3-1.src.rock - Could not find library file for YAML

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

Install openssl

Download openssl source code to decompress

Using openssl 1.1.0l, you need to change the version of luao SSL in kong dependency to: 20190612 (luao SSL depends on openssl, so you must install the corresponding openssl first)

cd /data/server/kong

wget https://www.openssl.org/source/openssl-1.1.0l.tar.gz

tar -xf openssl-1.1.0l.tar.gz

root User installation openssl

cd openssl-1.1.0l

./config shared zlib

make & make install

mv /usr/bin/openssl /usr/bin/openssl.bak

find / -name openssl

ln -s /usr/local/bin/openssl /usr/bin/openssl

echo "/usr/local/lib64/" >> /etc/ld.so.conf

ldconfig

openssl version -a

 

Test openssl installation results

openssl version -a

//Output the following

OpenSSL 1.1.0l 10 Sep 2019

built on: reproducible build, date unspecified

platform: linux-x86_64
