Installing API gateways Some of the pits and solutions that the Kong encounters

Install API Gateway Kong (https://getkong.org/) need to install Openresty and PostgreSQL First, here on my installation of the problems encountered and solutions to record, for your reference.

Openresty installation is very smooth, here simply paste:

Yum install-y pcre-devel openssl-devel gcc curl zlib zlib-devel
./configure--with-pcre-jit--with-ipv6--with-http_ Realip_module--with-http_ssl_module--with-http_stub_status_module--with-http_v2_module make
&& make Install
export path= "$PATH:/usr/local/openresty/bin"

Install PostgreSQL with Yum on the official website:

Yum Install https://download.postgresql.org/pub/repos/yum/9.4/redhat/rhel-6-x86_64/ pgdg-redhat94-9.4-2.noarch.rpm
yum Install postgresql94
yum install postgresql94-server
Service postgresql-9.4 Initdb

Here unexpectedly encountered can not initdb problem, and only show initing database [FAILED], also did not show the specific failure reason, no way can only uninstall, and then compile the source of the way to install, recommended installation here postgresql-9.5, because version 9.4 is running the Kong migrations Up command and inexplicably failed:

Paste the PostgreSQL compilation installation process:

wget https://ftp.postgresql.org/pub/source/v9.5.10/postgresql-9.5.10.tar.gz
Tar zxvf  postgresql-9.5.10.tar.gz
cd postgresql-9.5.10
./configure make
&& make install
useradd-d/ Home/postgres-m postgres
mkdir/usr/local/pgsql/data
chown postgres/usr/local/pgsql/data
su-postgres
/usr/local/pgsql/bin/initdb-d/usr/local/pgsql/data

Then modify the login authentication profile for PostgreSQL/usr/local/pgsql/data/pg_hba.conf

Change the ident inside to trust, otherwise Kong cannot connect to the database as follows:

Then start PostgreSQL:

/usr/local/pgsql/bin/pg_ctl-d/usr/local/pgsql/data-l ~/pgsql.log Start

Create the database required by the Kong Runtime:

[Postgres@iz239kse8fez ~]$ psql 
psql (9.5.10)
Type ' help ' for help.

postgres=# create User Kong;
postgres=# CREATE DATABASE Kong owner Kong;

Attach the close PostgreSQL command:

/usr/local/pgsql/bin/pg_ctl-d/usr/local/pgsql/data Stop

The installation of Kong is also very simple, paste it (remember to cut back to the root user):

wget Https://bintray.com/kong/kong-community-edition-rpm/rpm-O Bintray-kong-kong-community-edition-rpm.repo
MV bintray-kong-kong-community-edition-rpm.repo/etc/yum.repo.d/
Yum install-y kong-community-edition

Then Kong migrations up and Kong start is OK.

Everyone in the installation process if there are any other problems, you can leave a message to discuss ^ ^
