部署Kong
通过Docker部署

（1）创建网桥

docker network create kong-net
（2）安装postgres（你可以使用源码包安装，这里用docker安装）

docker run -d --name kong-database \
       --network=kong-net \
       -p 5432:5432 \
       -e "POSTGRES_USER=kong" \
       -e "POSTGRES_PASSWORD=Knight8888" \
       -e "POSTGRES_DB=kong" \
       -v kong_data:/var/lib/postgresql/data \
       postgres:9.6

(3) 查看版本

# 查看版本
kong version 
(4) 编辑配置文件

cp /etc/kong/kong.conf.default /etc/kong/kong.conf
vim /etc/kong/kong.conf，用于配置数据库的地址

database = postgres             # Determines which of PostgreSQL or Cassandra
                                 # this node will use as its datastore.
                                 # Accepted values are `postgres`,
                                 # `cassandra`, and `off`.
 
pg_host = 172.19.193.161             # Host of the Postgres server.
pg_port = 5432                  # Port of the Postgres server.
#pg_timeout = 5000               # Defines the timeout (in ms), for connecting,
                                 # reading and writing.
 
pg_user = kong                  # Postgres user.
pg_password =  kong@8888                 # Postgres user's password.
pg_database = kong              # The database name to connect to.
 
#pg_schema =                     # The database schema to use. If unspecified,
                                 # Kong will respect the `search_path` value of
                                 # your PostgreSQL instance.
 
pg_ssl = off                    # Toggles client-server TLS connections
                                 # between Kong and PostgreSQL.
                                 # Because PostgreSQL uses the same port for TLS
                                 # and non-TLS, this is only a hint. If the
                                 # server does not support TLS, the established
                                 # connection will be a plain one.
 
pg_ssl_verify = off             # Toggles server certificate verification if
                                 # `pg_ssl` is enabled.
                                 # See the `lua_ssl_trusted_certificate`
                                 # setting to specify a certificate authority.

通过yum安装部署PostGreSQL

（1）安装软件

$ yum install -y https://download.postgresql.org/pub/repos/yum/reporpms/EL-7-x86_64/pgdg-redhat-repo-latest.noarch.rpm
$ yum install -y postgresql96-server
$ systemctl enable postgresql-9.6

（2）修改环境变量

$ vim /etc/profile
$ export /usr/pgsql-9.6/bin:$PATH
$ source /etc/profile

（3）初始化数据

$ su - postgres
$ initdb -D /home/data/postgres/pgsql/data
$ psql

 
#创建kong数据库

$ CREATE USER kong; CREATE DATABASE kong OWNER kong;
$ ALTER USER  kong PASSWORD 'qq@123';  

 
#创建konga数据库

$ CREATE USER konga; CREATE DATABASE konga OWNER konga;
$ ALTER USER  konga PASSWORD 'qq@123';

(4) 修改数据目录

$ sed -i "s#/var/lib/pgsql/9.6/data/#/home/data/postgres/pgsql/data/#g" /usr/lib/systemd/system/postgresql-9.6.service
$ systemctl reload postgresql-9.6

修改配置文件:

$cat /etc/kong/kong.conf |grep "^pg_"
pg_host = 172.19.193.161             # Host of the Postgres server.
pg_port = 5432                  # Port of the Postgres server.
pg_user = kong                  # Postgres user.
pg_password = Knight8888                  # Postgres user's password.
pg_database = kong              # The database name to connect to.
pg_ssl = off                    # Toggles client-server TLS connections
pg_ssl_verify = off             # Toggles server certificate verification if

安装konga
（1）安装node.js环境

安装konga之前我们先安装一下node.js环境，

$ cd /opt/
$ wget https://nodejs.org/dist/v10.16.0/node-v10.16.0-linux-x64.tar.xz
$ tar xf node-v10.16.0-linux-x64.tar.xz
$ mv node-v10.16.0-linux-x64 /usr/local/node

 
# 验证安装有效性

$ node -v
$ npm -v

 
#安装pm2
npm  install -g pm2
环境变量:

## set node env
export NODE=/usr/local/node
export PATH=$PATH:$NODE/bin

（2）开始安装

$ cd /home/data
$ git clone https://github.com/pantsel/konga.git --depth=1
#替换源
$ echo "registry = https://registry.npm.taobao.org" > ~/.npmrc
$ cd konga
# 安装npm 依赖
$ npm i
