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
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
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。
