一、系统环境
[root@kong ~]# service iptables status iptables: Firewall is not running. [root@kong ~]# getenforce Disabled [root@kong ~]# cat /etc/system-release CentOS release 6.7 (Final) [root@kong ~]# uname -a Linux kong 2.6.32-573.el6.x86_64 #1 SMP Thu Jul 23 15:44:03 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
二、kong的安装
根据kong的官网文档进行安装 官网：https://konghq.com/install/
1、yum源配置
[root@kong ~]# cat /etc/yum.repos.d/bintray-kong-kong-community-edition-rpm.repo [bintraybintray-kong-kong-community-edition-rpm] name=bintray-kong-kong-community-edition-rpm baseurl=https://kong.bintray.com/kong-community-edition-rpm/centos/6 gpgcheck=0 repo_gpgcheck=0 enabled=1
2、安装kong 默认安装的 kong-0.10.4-1.noarch，官网已经更新到了0.13.x了，也可以手动下载最新版的rpm包安装
[root@kong ~]# yum install -y kong
如果安装是报如下错误，就在/etc/yum.conf 配置文件 sslverify=false后，重新执行上面命令
https://kong.bintray.com/kong-community-edition-rpm/centos/6/kong-community-edition-0.10.4.el6.noarch.rpm: [Errno 14] Peer cert cannot be verified or peer cert invalid
3、安装 kong 需要的数据库，默认选择的是postgreSQL，kong支持2种数据库存储（postgreSQL 和 Cassandra ）
postgreSQL官网：https://www.postgresql.org/download/
Cassandra官网：http://cassandra.apache.org/download/
这里我们以postgreSQL为例进行安装
a、配置yum源
https://www.postgresql.org/download/linux/redhat/
yum install https://download.postgresql.org/pub/repos/yum/10/redhat/rhel-6-x86_64/pgdg-centos10-10-2.noarch.rpm yum install postgresql10 yum install postgresql10-server service postgresql-10 initdb chkconfig postgresql-10 on
b、修改postgreSQL配置文件
/var/lib/pgsql/10/data/postgresql.conf
listen_addresses = 'localhost' 替换成如下： listen_addresses = '*'
/var/lib/pgsql/10/data/pg_hba.conf
host all all 127.0.0.1/32 ident 换成如下： host all all 127.0.0.1/32 trust
c、启动postgreSQL
service postgresql-10 start
d、创建kong需要的库、授权 并 把相关的数据写入库
[root@base ~]# su - postgres -bash-4.1$ psql psql (8.4.20, server 10.3) WARNING: psql version 8.4, server version 10.0. Some psql features might not work. Type "help" for help. postgres=# CREATE USER kong; CREATE DATABASE kong OWNER kong; CREATE ROLE CREATE DATABASE postgres=# quit postgres-# q -bash-4.1$ exit logout [root@base ~]# kong migrations up ................... response-ratelimiting migrated up to: 2016-08-04-321512_response-rate-limiting_policies migrating acl for database kong acl migrated up to: 2015-08-25-841841_init_acl 32 migrations ran
e、修改普通用户描述符，至少4096
ulimit -HSn 65535
echo "ulimit -HSn 65535" >> /etc/rc.local
4、启动 kong
[root@base ~]# kong start Kong started [root@base ~]# netstat -lntp|grep nginx tcp 0 0 0.0.0.0:8000 0.0.0.0:* LISTEN 3984/nginx tcp 0 0 0.0.0.0:8001 0.0.0.0:* LISTEN 3984/nginx tcp 0 0 0.0.0.0:8443 0.0.0.0:* LISTEN 3984/nginx tcp 0 0 0.0.0.0:8444 0.0.0.0:* LISTEN 3984/nginx [root@base ~]# curl -i -X GET http://localhost:8001/ HTTP/1.1 200 OK Date: Thu, 05 Apr 2018 08:22:56 GMT Content-Type: application/json; charset=utf-8 Transfer-Encoding: chunked Connection: keep-alive Access-Control-Allow-Origin: * Server: kong/0.10.4 {"timers":{"running":0,"pending":5},"configuration":{"admin_error_log":"logs/error.log","cassandra_lb_policy":"RoundRobin","admin_access_log":"logs/admin_access.log","ca .................. ..............................
