雲計算---openstack實例共享80、443端口

前言

由於openstack使用的是apache,因此不能共享80端口,但建立的許多雲主機,雖然能夠經過rinetd進行跳轉,但有時須要直接訪問80端口,因此這裏咱們選擇包含了nginx的openrety。nginx

1.1. 安裝openresty

1.centos系統中添加openresty倉庫apache

 

#yum install yum-utils

#yum-config-manager --add-repo https://openresty.org/package/centos/openresty.repo

  

2.安裝軟件包centos

#yum install openresty

  

3.安裝命令行工具瀏覽器

#yum install openresty-resty

  

1.2. 配置openresty

1.進入nginx目錄app

#cd /usr/local/openresty/nginx/conf/

  

2.編輯nginx配置文件tcp

#vi nginx.conf工具

 

user  root;

worker_processes  12;

 

error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;
#pid logs/nginx.pid; events { worker_connections 10240; } http { include 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 logs/access.log main; sendfile on; #tcp_nopush on; #keepalive_timeout 0; keepalive_timeout 65; #gzip on; include conf.d/*; server { listen 80;
# server_name 域名;
#指定日誌路徑 access_log logs/access.log main; error_log logs/error.log; # location / { proxy_pass http://172.17.17.113; } } }

  

  

3.在當前目錄下建立conf.d文件夾spa

#mkdir /usr/local/openresty/nginx/conf/conf.d

#cd conf.d

  

 

4.建立要被讀取的文件,目前定義爲每臺機器建立一臺,這裏定義添加一臺aa機器,則建立aa.conf命令行

#vi aa.confrest

server {
    listen       80;
#綁定https
    include /usr/local/openresty/nginx/https/https.conf;
#綁定域名
    server_name  域名;
#指定日誌路徑
    access_log  logs/ope.access.log  main;
    error_log  logs/ope.error.log;

#指定經過域名跳轉端口
    location / {

        proxy_pass http://172.17.17.136:8081;

    }

}

  


1.3. 
使用openresty 

1.檢測nginx是否配置正確

#openresty -t

nginx: the configuration file /usr/local/openresty/nginx/conf/nginx.conf syntax is ok

nginx: configuration file /usr/local/openresty/nginx/conf/nginx.conf test is successful

  


2.重載openresty 

#openresty -s reload

  

3.驗證

在瀏覽器上輸入綁定的域名便可直接訪問80或者所需端口。
