前言
因為openstack使用的是apache,是以不能共享80端口,但建立的許多雲主機,雖然可以通過rinetd進行跳轉,但有時需要直接通路80端口,是以這裡我們選擇包含了nginx的openrety。
1.1. 安裝openresty
1.向centos系統中添加openresty倉庫
#yum install yum-utils
#yum-config-manager --add-repo https://openresty.org/package/centos/openresty.repo
2.安裝軟體包
#yum install openresty
3.安裝指令行工具
#yum install openresty-resty
1.2. 配置openresty
1.進入nginx目錄
#cd /usr/local/openresty/nginx/conf/
2.編輯nginx配置檔案
#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;
#指定日志路徑
access_log logs/access.log main;
error_log logs/error.log;
#
location / {
proxy_pass http://172.17.17.113;
}
}
}
3.在目前目錄下建立conf.d檔案夾
#mkdir /usr/local/openresty/nginx/conf/conf.d
#cd conf.d
4.建立要被讀取的檔案,目前定義為每台機器建立一台,這裡定義添加一台aa機器,則建立aa.conf。
#vi aa.conf
server {
listen 80;
#綁定https
include /usr/local/openresty/nginx/https/https.conf;
#綁定域名
server_name 域名;
#指定日志路徑
access_log logs/ope.access.log main;
error_log logs/ope.error.log;
#指定通過域名跳轉端口
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.重載openresty
#openresty -s reload
3.驗證
在浏覽器上輸入綁定的域名即可直接通路80或者所需端口。
