一、下载安装kong和postgresql

wget https://dl.bintray.com/mashape/kong-rpm-el6-0.10.x/0.10.3/kong-0.10.3.el6.noarch.rpm

rpm  -ivh kong-0.10.3.el6.noarch.rpm 

yum install https://download.postgresql.org/pub/repos/yum/9.6/redhat/rhel-6-x86_64/pgdg-centos96-9.6-3.noarch.rpm -y

yum install postgresql96 -y

yum install postgresql96-server -y


二、初始化启动postgresql 

service postgresql-9.6 initdb

chkconfig postgresql-9.6 on
service postgresql-9.6 start

三、设置postgresql密码，建立kong 库

1、su postgres
2、psql
    alter user postgres with password '1234560.';
    CREATE USER kong; CREATE DATABASE kong OWNER kong;

    \q

四、修改kong链接数据得级别为password

1、vi /var/lib/pgsql/9.6/data/pg_hba.conf

     # TYPE DATABASE USER ADDRESS METHOD

     # "local" is for Unix domain socket connections only
    local all all                                              password
    # IPv4 local connections:
    host all all 127.0.0.1/32                          password
    host all all 0.0.0.0/0                                password
    # IPv6 local connections:
    host all all ::1/128                                   ident

2、service postgresql-9.6 restart

五、设置kong 连接postgresql 密码

1、cd  /etc/kong/

2、cp kong.conf.default kong.conf

3、vim kong.conf 

      pg_user = kong # The username to authenticate if required.  
      pg_password = kong # The password to authenticate if required.
      pg_database = kong

4、vim  /etc/profile
        export KONG_SERF_PATH="/usr/local/bin/serf"

六、启动kong

kong start
