APISIX的安装和简单使⽤
APISIX 是⼀个云原⽣、⾼性能、可扩展的微服务 API ⽹关。
它是基于 Nginx 和 etcd 来实现，和传统 API ⽹关相⽐，APISIX 具备动态路由和插件热加载，特别适合微服务体系下的 API 管理。
APISIX安装
# 安装 OpenResty, etcd 和编译⼯具
nginx和网关怎么配合使用sudo yum install -y etcd openresty curl git gcc luarocks lua-devel
# 开启 etcd server
sudo service etcd start
依赖openresty的新版本 OpenResty 1.15.8.3。检查下etcd是否已经正常启动。
ps aux |grep etcd
etcd 2769 2.2 4.2 10856200 21364 ? Ssl 14:54 0:00 /usr/bin/etcd --name=default --data-dir=/var/lib/d --listen-client-urls=loca lhost:2379
可以看到，监听的端⼝号是2379.也可以看下etcd的配置，也可以看到端⼝号。
/etc/f
github/apache/incubator-apisix/releases/download/1.3/apisix-1.arch.rpm
⼿动安装，并且启动apisix
rpm -ivh apisix-1.arch.rpm
准备中... >>>>>>### [100%]
正在升级/安装...
1:apisix-1.3-0 >>>>>>### [100%]
apisix start
检查下apisix是否启动成功
ps aux |grep nginx
root 2978 0.0 0.5 178996 2616 ? Ss 08:14 0:00 nginx: master process openresty -p /usr/local/apisix -c /usr/local/apisix/f nobody 2979 0.6 2.4 191600 12368 ? R 08:14 0:00 nginx: worker process
nobody 2980 0.1 0.4 173672 2120 ? S 08:14 0:00 nginx: cache manager process
nobody 2981 0.0 0.4 173672 2120 ? S 08:14 0:00 nginx: cache loader process
启动成功，也可以到apisix的Nginx conf的配置路径。
APISIX简单使⽤
我们先配置下upstream
curl"127.0.0.1:9080/apisix/admin/upstreams/50" -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
> {
> "type": "roundrobin",
> "nodes": {
> "127.0.0.1:7080": 1
> }
> }'
{"node":{"value":{"type":"roundrobin","nodes":{"127.0.0.1:7080":1},"hash_on":"vars","id":"50"},"createdIndex":22,"key":"\/apisix\/upstreams\/50","modifiedInd ex":22},"prevNode":{"value":"{\"hash_on\":\"vars\",\"id\":\"50\",\"nodes\":{\":80\":1},\"type\":\"roundrobin\"}","createdIndex":19,"key":"\/apisix\/upstre ams\/50","modifiedIndex":19},"action":"set"}
再给刚刚配置的upstream配置router
curl"127.0.0.1:9080/apisix/admin/routes/5" -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
> {
> "uri": "/get",
> "host": "",
> "upstream_id": 50
> }'
{"node":{"value":{"host":"","upstream_id":50,"uri":"\/get","priority":0},"createdIndex":25,"key":"\/apisix\/routes\/5","modifiedIndex":25},"prevNode":{" value":"{\"host\":\"\",\"plugins\":{\"proxy-rewrite\":{\"scheme\":\"https\"}},\"uri\":\"\\\/get\",\"upstream_id\":50,\"priority\":0}","createdIndex":24,"key":"\/ apisix\/routes\/5","modifiedIndex":24},"action":"set"}
现在的流程就是这样的的。
终端请求/get->APISIX代理-> 127.0.0.1:7080
我们再启动⼀个Nginx服务，使得上游服务 127.0.0.1:7080/get 可以正常提供服务。
vim /usr/local/openresty/nginx/f
添加7080的端⼝服务
server {
listen 7080;
location /get {
echo"success";
}
}
启动Nginx WEB服务
sudo /usr/local/openresty/nginx/sbin/nginx -c /usr/local/openresty/nginx/f
curl'127.0.0.1:7080/get'
success
说明7080能够正常提供服务了
我们在终端试下是否代理成功
curl -i -X GET "127.0.0.1:9080/get?foo1=bar1&foo2=bar2" -H "Host: "
HTTP/1.1 200 OK
Content-Type: application/octet-stream
Transfer-Encoding: chunked
Connection: keep-alive
Server: APISIX web server
Date: Sun, 28 Jun 2020 15:52:03 GMT
success
打印了success，说明整个⽹络流程是通畅的。
APISIX控制台安装
出现下⾯的报错，可能是etced服务忘记启动了
connection refused
启动下etcd服务就正常了
service etcd start
如果是虚拟机或者docker机器的话，可能需要打开admin的访问显⽰
vim /usr/local/apisix/conf/config.yaml
到 allow_admin
- 127.0.0.0/24 该为 - all
就是允许所有IP访问，⽣产环境可不能这样，有⾮常⼤的安全风险
etcd 命令⾏简单使⽤
etcd 是⼀个分布式、可靠的 key-value 存储的分布式系统，主要⽤于服务发现。最著名的k8s就是⽤etcd存储配置数据的。
命令⾏主要使⽤ etcdctl 执⾏ etcd 命令，先看下帮助菜单
etcdctl -h
NAME:
etcdctl - A simple command line client for etcd.
WARNING:
Environment variable ETCDCTL_API is not set; defaults to etcdctl v2.
Set environment variable ETCDCTL_API=3 to use v3 API or ETCDCTL_API=2 to use v2 API.
USAGE:
etcdctl [global options]command[command options][]
VERSION:
3.3.11
COMMANDS:
backup backup an etcd directory
cluster-health check the health of the etcd cluster
mk make a new key with a given value
mkdir make a new directory
rm remove a key or a directory
rmdir removes the key if it is an empty directory or a key-value pair
get retrieve the value of a key
ls retrieve a directory
set set the value of a key
setdir create a new directory or update an existing directory TTL
update update an existing key with a given value
updatedir update an existing directory
watch watch a key for changes
exec-watch watch a key for changes and exec an executable
member member add, remove and list subcommands
user user add, grant and revoke subcommands
role role add, grant and revoke subcommands
auth overall auth controls
最常⽤⼏个命令 ls get set rm rmdir mk mkdir等等，名字都⽐较通俗易懂。
etcdctl ls
/apisix
etcdctl ls /apisix
/apisix/upstreams
/apisix/node_status
/apisix/ssl
/apisix/routes
/apisix/services
etcdctl ls /apisix/upstreams
/apisix/upstreams/50
etcdctl get /apisix/upstreams/50
{"hash_on":"vars","id":"50","nodes":{"127.0.0.1:7080":1},"type":"roundrobin"}
