如何做社交网站拼多多女装关键词排名

安装java环境

查询 java安装包
196  yum list java*
安装java8197  yum install -y java-1.8.0-openjdk.x86_64
检验java8是否安装成功。198  java -version

2个tomcat准备

另外一个tomcat区别在于：配置文件。conf/server.xml

启动tomcat

[root@localhost bin]# ./startup.sh

测试tomcat

[root@localhost bin]# curl http://localhost:8081/test/index.html
tomcat-8081,81,81
[root@localhost bin]# curl http://localhost:8082/test/index.html
tomcat-8082,82,82
[root@localhost bin]#

nginx安装：

目录：/etc/yum.repos.d/241  vi nginx.repo文件内容：

nginx做负载均衡

修改/etc/nginx/nginx.conf

/test/index.html[root@192 nginx]# cat nginx.conf user  nginx;
worker_processes  auto;error_log  /var/log/nginx/error.log notice;
pid        /var/run/nginx.pid;events {worker_connections  1024;
}http {include       /etc/nginx/mime.types;default_type  application/octet-stream;log_format  main  '$remote_addr - $remote_user [$time_local] "$request" ''$status $body_bytes_sent "$http_referer" ''"$http_user_agent" "$http_x_forwarded_for"';access_log  /var/log/nginx/access.log  main;sendfile        on;#tcp_nopush     on;keepalive_timeout  65;#gzip  on;include /etc/nginx/conf.d/*.conf;# diyupstream myServer {server localhost:8081;server localhost:8082;}server {listen 80;server_name myNginx.com;location /test/ {proxy_pass http://myServer;}}
}
[root@192 nginx]#

重新加载配置文件

启动nginx:/usr/sbin/nginx
[root@192 nginx]# /usr/sbin/nginx -s reload

域名：

myNginx.com

配置linux域名：

配置宿主机域名：

kong负载均衡

先看nginx

# diyupstream myServer {server localhost:8081;server localhost:8082;}server {listen 80;server_name myNginx.com;location /test/ {proxy_pass http://myServer;}}

kong:

upstream

查看：http://127.0.0.1:8001/upstreams。

添加：

[root@localhost etc]# curl -X POST http://localhost:8001/upstreams --data "name=myServer"{"client_certificate":null,"hash_on":"none","id":"933c3aab-85da-4dc1-a34f-2fae01b56b48","hash_on_header":null,"algorithm":"round-robin","hash_on_query_arg":null,"hash_on_uri_capture":null,"healthchecks":{"passive":{"type":"http","healthy":{"http_statuses":[200,201,202,203,204,205,206,207,208,226,300,301,302,303,304,305,306,307,308],"successes":0},"unhealthy":{"tcp_failures":0,"timeouts":0,"http_failures":0,"http_statuses":[429,500,503]}},"active":{"headers":null,"http_path":"/","https_sni":null,"https_verify_certificate":true,"concurrency":10,"unhealthy":{"tcp_failures":0,"timeouts":0,"http_failures":0,"http_statuses":[429,404,500,501,502,503,504,505],"interval":0},"timeout":1,"type":"http","healthy":{"successes":0,"http_statuses":[200,302],"interval":0}},"threshold":0},"hash_on_cookie":null,"hash_on_cookie_path":"/","hash_fallback":"none","hash_fallback_header":null,"hash_fallback_query_arg":null,"hash_fallback_uri_capture":null,"host_header":null,"tags":null,"created_at":1669830017,"name":"myServer","slots":10000}[root@localhost etc]#

再检查一下，做确认。

Target

查询：http://127.0.0.1:8001/upstreams/myServer/targets

添加：

[root@localhost etc]# curl -X POST http://localhost:8001/upstreams/myServer/targets --data "target=10.0.2.4:8081"{"upstream":{"id":"933c3aab-85da-4dc1-a34f-2fae01b56b48"},"tags":null,"id":"499d1373-45fc-44b5-b952-1e590f3be680","weight":100,"created_at":1669830273.544,"target":"10.0.2.4:8081"}[root@localhost etc]# curl -X POST http://localhost:8001/upstreams/myServer/targets --data "target=10.0.2.4:8082"
{"upstream":{"id":"933c3aab-85da-4dc1-a34f-2fae01b56b48"},"tags":null,"id":"093cc5cf-ac84-4bb9-b0c7-0289fec7da6a","weight":100,"created_at":1669830307.884,"target":"10.0.2.4:8082"}[root@localhost etc]#

添加完，查看一下。

Service

查看service：http://127.0.0.1:8001/services

添加：

[root@localhost etc]# curl -X POST http://localhost:8001/services --data "name=myService" --data "host=myServer"{"client_certificate":null,"tls_verify_depth":null,"id":"a5997d4d-c868-43fe-8a73-9db62c5410f8","created_at":1669830610,"updated_at":1669830610,"read_timeout":60000,"protocol":"http","host":"myServer","name":"myService","enabled":true,"retries":5,"port":80,"write_timeout":60000,"tags":null,"ca_certificates":null,"connect_timeout":60000,"tls_verify":null,"path":null}[root@localhost etc]#

查看：http://127.0.0.1:8001/services

Route

查看route：http://127.0.0.1:8001/services/myService/routes

添加：

[root@localhost etc]# curl -X POST http://localhost:8001/services/myService/routes --data "name=myRoute" --data "paths[]=/test"{"paths":["/test"],"methods":null,"sources":null,"destinations":null,"id":"231fc5ba-a1f1-4d6f-9fcb-eac4e897923d","created_at":1669830883,"updated_at":1669830883,"service":{"id":"a5997d4d-c868-43fe-8a73-9db62c5410f8"},"https_redirect_status_code":426,"regex_priority":0,"protocols":["http","https"],"path_handling":"v0","name":"myRoute","strip_path":true,"snis":null,"hosts":null,"tags":null,"headers":null,"request_buffering":true,"response_buffering":true,"preserve_host":false}[root@localhost etc]#

测试负载均衡：

[root@localhost etc]# curl http://localhost:8000/test/test/index.html
tomcat-8082,82,82
[root@localhost etc]# curl http://localhost:8000/test/test/index.html
tomcat-8081,81,81
[root@localhost etc]# curl http://localhost:8000/test/test/index.html
tomcat-8082,82,82
[root@localhost etc]# curl http://localhost:8000/test/test/index.html
tomcat-8081,81,81
[root@localhost etc]# curl http://localhost:8000/test/test/index.html
tomcat-8082,82,82
[root@localhost etc]# curl http://localhost:8000/test/test/index.html
tomcat-8081,81,81
[root@localhost etc]#

成功。

请求需要两个test的原因。

加了/。 相当于匹配到目标地址的 根路径。

# diyupstream myServer {server localhost:8081;server localhost:8082;}server {listen 80;server_name myNginx.com;location /test/ {proxy_pass http://myServer/;}}

总结：

upstream: 对应一组 target节点，实现负载均衡。（还可以指定权重）

target: 对应的具体的服务url。controller。

route: 负责将请求，匹配，映射到 upstream。

service: 将服务节点，指定到一个upstream（具体的服务）。
