云计算---openstack实例共享80、443端口

前言

因为openstack使用的是apache,所以不能共享80端口,但创建的许多云主机,虽然可以通过rinetd进行跳转,但有时需要直接访问80端口,所以这里我们选择包含了nginx的openrety。

1.1. 安装openresty

1.centos系统中添加openresty仓库

#yum install yum-utils

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

  

2.安装软件包

#yum install openresty

  

3.安装命令行工具

#yum install openresty-resty

  

1.2. 配置openresty

1.进入nginx目录

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

  

2.编辑nginx配置文件

#vi nginx.conf

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;
#指定日志路径 access_log logs/access.log main; error_log logs/error.log; # location / { proxy_pass http://172.17.17.113; } } }

  

  

3.在当前目录下创建conf.d文件夹

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

#cd conf.d

  

4.创建要被读取的文件,目前定义为每台机器创建一台,这里定义添加一台aa机器,则创建aa.conf

#vi aa.conf

server {
    listen       80;
#绑定https
    include /usr/local/openresty/nginx/https/https.conf;
#绑定域名
    server_name  域名;
#指定日志路径
    access_log  logs/ope.access.log  main;
    error_log  logs/ope.error.log;

#指定通过域名跳转端口
    location / {

        proxy_pass http://172.17.17.136:8081;

    }

}

  


1.3. 
使用openresty 

1.检测nginx是否配置正确

#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.重载openresty 

#openresty -s reload

  

3.验证

在浏览器上输入绑定的域名即可直接访问80或者所需端口。
