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。
