之前在macos系统测试安装psql和kong，但是实际环境中，大部分是部署在linux服务器上。下面记录了在centos7上部署postgresql和kong的总结以及遇到的一些问题的解决。
查看centos版本：
$ cat /etc/redhat-release CentOS Linux release 7.2.1511 (Core)
部署版本：
kong: v0.13.1
postgresql: v10.4 (注意：psql版本必须与kong版本对应)
$ sudo yum install -y pcre pcre-devel
$ sudo yum install -y pcre pcre-devel
$ sudo yum install -y zlib zlib-devel
$ sudo yum install -y openssl openssl-devel
$ /usr/local/bin/kong start 2018/06/08 12:07:55 [warn] postgres database ‘kong‘ is missing migration: (response-transformer) 2016-05-04-160000_resp_trans_schema_changes Error: /usr/local/share/lua/5.1/kong/cmd/start.lua:34: [postgres error] the current database schema does not match this version of Kong. Please run `kong migrations up` to update/initialize the database schema. Be aware that Kong migrations should only run from a single node, and that nodes running migrations concurrently will conflict with each other and might corrupt your database schema!

$ passwd postgres
Changing password for user postgres.
New password:
BAD PASSWORD: The password contains the user name in some form
Retype new password:
passwd: all authentication tokens updated successfully.
为了安全以及满足 Kong 初始化的需求，需要在建立一个 postgre 用户 kong 和对应的 linux 用户 kong，并新建数据库 kong。
# 新建 linux kong 用户 $ sudo adduser kong # 使用管理员账号登录 psql 创建用户和数据库 # 切换 postgres 用户 # 切换 postgres 用户后，提示符变成 `-bash-4.3$` $ su postgres # 进入psql控制台，此时会进入到控制台（系统提示符变为‘postgres=#‘） bash-4.3$ psql could not change directory to "/root": Permission denied psql (10.4) Type "help" for help. #为管理员用户postgres修改密码，之前改过了这里就不用改了 postgres=# password postgres #建立新的数据库用户（和之前建立的系统用户要一样） postgres=# create user kong with password ‘kong‘; CREATE ROLE #为新用户建立数据库 postgres=# create database kong owner kong; CREATE DATABASE #把新建的数据库权限赋予 kong postgres=# grant all privileges on database kong to kong; GRANT #退出控制台 postgres=# \q bash-4.3$
注意：在 psql 控制台下执行命令，一定记得在命令后添加分号。
而且postgresql的用户要和系统用户一样：
$ cat /etc/passwd ... postgres:x:26:26:PostgreSQL Server:/var/lib/pgsql:/bin/bash kong:x:1002:1002::/home/kong:/bin/bash
问题一：
用命令行登录，在root账户下登录postgresql 数据库会提示权限问题：
$ psql -U kong -d kong -h 127.0.0.1 -p 5432 psql: FATAL: Ident authentication failed for user "kong"
原因是postgres没有配置对外访问策略。
$ vim /var/lib/pgsql/10/data/pg_hba.conf
# 增加如下两条配置
$ vim var/lib/pgsql/10/data/postgresql.conf
# CONNECTIONS AND AUTHENTICATION #------------------------------------------------------------------------------ # - Connection Settings - listen_addresses = ‘*‘ # what IP address(es) to listen on;
修改以上两个配置文件后，重启postgresql服务：
$ sudo systemctl restart postgresql-10.service $ psql -U kong -d kong -h 127.0.0.1 -p 5432 psql (10.4) Type "help" for help. kong=> \l List of databases Name | Owner | Encoding | Collate | Ctype | Access privileges -----------+----------+-----------+---------+-------+----------------------- kong | kong | SQL_ASCII | C | C | =Tc/kong + | | | | | kong=CTc/kong postgres | postgres | SQL_ASCII | C | C | template0 | postgres | SQL_ASCII | C | C | =c/postgres + | | | | | postgres=CTc/postgres template1 | postgres | SQL_ASCII | C | C | =c/postgres + | | | | | postgres=CTc/postgres (4 rows) kong=>

kong这块按照官网的方法不成功，最终下载了rpm包安装成功的。
