openstack shares instance code for ports 80 and 443

preface

Since openstack USES apache, it is not possible to share port 80, but many of the cloud hosts created, although they can jump through rinetd, sometimes require direct access to port 80, so here we chose openrety, which includes nginx.

1.1. Installation openresty

1. Add openresty warehouse to centos system

#yum install yum-utils

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

2. Install the package

#yum install openresty

3. Install the command line tools

#yum install openresty-resty

1.2. The configuration openresty

1. Enter the nginx directory

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

2. Edit the nginx profile

#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  The domain name ;
  # Specify log path 
  access_log logs/access.log main;
  error_log logs/error.log;

  # 
  location / {
   proxy_pass http://172.17.17.113;
  }
 }
}

3. Create the conf.d folder in the current directory

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

#cd conf.d

4. Create the files to be read, currently defined as 1 per machine, here defined as adding 1 aa machine, then create ES41en.conf.

#vi aa.conf
server {
 listen  80;
# The binding https include /usr/local/openresty/nginx/https/https.conf;
# Binding domain 
 server_name  The domain name ;
# Specify log path 
 access_log logs/ope.access.log main;
 error_log logs/ope.error.log;

# Specifies a jump port through the domain name 
 location / {

  proxy_pass http://172.17.17.136:8081;

 }
}

1.3. Use openresty

1. Check whether nginx is configured correctly

#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. Overloaded openresty

#openresty -s reload

3. Verify

Enter the bound domain name in your browser to access 80 or the desired port directly.
