配置kong

关闭防火墙，重启docker – 重要

1 2	systemctl stop firewalld.service systemctl restart docker

cp /etc/kong/kong.conf.default /etc/kong/kong.conf
vi /etc/kong/kong.conf
# 修改如下内容
database = postgres
pg_host = 192.168.194.100 #这里是对外地址，填写部署所在服务器地址
pg_port = 5432
pg_timeout = 5000


pg_user = kong
pg_password = kongpass
pg_database = kong

dns_resolver = 192.168.194.100:8600 #配置consul的dns端口
admin_gui_listen = 192.168.194.100:8002, 192.168.194.100:8445 ssl
admin_listen = 192.168.194.100:8001 reuseport backlog=16384, 192.168.194.100:8444 http2 ssl reuseport backlog=16384
proxy_listen = 0.0.0.0:8000 reuseport backlog=16384, 0.0.0.0:8443 http2 ssl reuseport backlog=16384

初始化kong的数据库并启动

kong migrations bootstrap up -c /etc/kong/kong.conf  #初始化生成数据库
kong start -c /etc/kong/kong.conf

#添加防火墙规则 -- 如果开启了防火墙
firewall-cmd --zone=public --add-port=8002/tcp --permanent
firewall-cmd --zone=public --add-port=8000/tcp --permanent
sudo firewall-cmd --reload

看到这个代表启动成功

前面已经配置了dns_resolver接下来如下配置即可

在Gateway Service里面将host改成consul里的[Service Name].service.consul将port改为80端口
