先安装PostgreSQL，请参见CentOS下PostgreSQL 12 安装。然后为Kong初始化数据库。

su - postges
su: user postges does not exist
[root@kong postgresql]# su - postgres
上一次登录：日 12月 15 08:17:06 CST 2019pts/0 上
-bash-4.2$ psql
用户 postgres 的口令：
psql (12.1)
输入 "help" 来获取帮助信息.

postgres=# CREATE USER kong WITH PASSWORD '1111';
CREATE ROLE
postgres=# CREATE DATABASE kong OWNER kong;
CREATE DATABASE
postgres=# GRANT ALL PRIVILEGES ON DATABASE kong TO kong;
GRANT
postgres=# \q
-bash-4.2$ psql -U kong -d kong -h 127.0.0.1 -p 5432
用户 kong 的口令：
psql (12.1)
输入 "help" 来获取帮助信息.

kong=> \q
-bash-4.2$ exit
登出

下载rpm包，https://bintray.com/kong/kong-rpm/centos/view/files/centos/7#files/centos/7。

安装所需工具。

yum install -y gcc pcre-devel zlib-devel openssl-devel

vi /etc/security/limits.conf
*                soft    nofile          4096

#重启生效
reboot

安装Kong。

mkdir kong
cd kong

#将下载的文件上传到此目录。

yum install -y epel-release
yum install -y kong-1.4.2.el7.amd64.rpm --nogpgcheck

配置Kong。

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

vi /etc/kong/kong.conf
......
admin_listen = 0.0.0.0:8001, 0.0.0.0:8444 ssl
......
database = postgres              # Determines which of PostgreSQL or Cassandra
                                 # this node will use as its datastore.
                                 # Accepted values are `postgres`,
                                 # `cassandra`, and `off`.

pg_host = 127.0.0.1              # 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 = 1111               # Postgres user's password.
pg_database = kong               # The database name to connect to.
......

kong check
configuration at /etc/kong/kong.conf is valid

初始化Kong，Kong会向数据库写入初始化数据。

kong migrations bootstrap

启动Kong。

kong start
Kong started

kong health
nginx.......running

Kong is healthy at /usr/local/kong

Kong的8001为管理端口，8000为Proxy端口，如果都能访问，表示Kong安装成功。
