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.向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。
