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

  1. su - postges
  2. su: user postges does not exist
  3. [root@kong postgresql]# su - postgres
  4. 上一次登录：日 12月 15 08:17:06 CST 2019pts/0 上
  5. -bash-4.2$ psql
  6. 用户 postgres 的口令：
  7. psql (12.1)
  8. 输入 "help" 来获取帮助信息.
  10. postgres=# CREATE USER kong WITH PASSWORD '1111';
  11. CREATE ROLE
  12. postgres=# CREATE DATABASE kong OWNER kong;
  13. CREATE DATABASE
  14. postgres=# GRANT ALL PRIVILEGES ON DATABASE kong TO kong;
  15. GRANT
  16. postgres=# \q
  17. -bash-4.2$ psql -U kong -d kong -h 127.0.0.1 -p 5432
  18. 用户 kong 的口令：
  19. psql (12.1)
  20. 输入 "help" 来获取帮助信息.
  22. kong=> \q
  23. -bash-4.2$ exit
  24. 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。

  1. yum install -y gcc pcre-devel zlib-devel openssl-devel
  3. vi /etc/security/limits.conf
  4. *                soft    nofile          4096
  6. #重启生效
  7. reboot

安装Kong。

  1. mkdir kong
  2. cd kong
  4. #将下载的文件上传到此目录。
  6. yum install -y epel-release
  7. yum install -y kong-1.4.2.el7.amd64.rpm --nogpgcheck

配置Kong。

  1. cp /etc/kong/kong.conf.default /etc/kong/kong.conf
  3. vi /etc/kong/kong.conf
  4. ......
  5. admin_listen = 0.0.0.0:8001, 0.0.0.0:8444 ssl
  6. ......
  7. database = postgres              # Determines which of PostgreSQL or Cassandra
  8.                                  # this node will use as its datastore.
  9.                                  # Accepted values are `postgres`,
  10.                                  # `cassandra`, and `off`.
  12. pg_host = 127.0.0.1              # Host of the Postgres server.
  13. pg_port = 5432                   # Port of the Postgres server.
  14. #pg_timeout = 5000               # Defines the timeout (in ms), for connecting,
  15.                                  # reading and writing.
  17. pg_user = kong                   # Postgres user.
  18. pg_password = 1111               # Postgres user's password.
  19. pg_database = kong               # The database name to connect to.
  20. ......
  22. kong check
  23. 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。

  1. kong migrations bootstrap

启动Kong。

  1. kong start
  2. Kong started
  4. kong health
  5. nginx.......running
  7. 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。

  1. curl http://localhost:8001 -s | python -m json.tool
