Keepalived+nginx+apache Double-Live build (dual-NIC mode)

Previously wrote an article "Keepalived+nginx+apache and double Live Build test", the test environment only a network card, the dual-live IP is on the network card.

background: The automatic operation and maintenance platform of the front-mounted machine deployed in the cloud platform, the server has two network cards, respectively, corresponding to the out-of-band IP and business IP, the cloud platform of the managed server access to out-of-band virtual IP, non-cloud platform physical server access to the virtual IP of the business.

VMware version : 12.5.2 build-4638234

1.vmware New network card

Open ' Virtual network editor ':

The ' VMnet0 ' and ' VMnet2 ' respectively correspond to the PC physical network card and the wireless network card:

New network card and configuration:

2.keepalived Configuration

check_nginx.sh script configuration with previous articles

3.nginx Configuration

The two Nginx servers are configured as follows:

[[email protected] keepalived]# more /usr/local/nginx/conf/nginx.conf#user   nobody;worker_processes  1; #error_log   logs/error.log; #error_log   logs/error.log   notice; #error_log   logs/error.log  info; #pid          logs/nginx.pid;events {    worker_connections  1024;} 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;    upstream  webser{             server  172.27.9.125:1180;             server  172.27.9.126:1180;             server  172.27.18.127:1180;             server  172.27.18.128:1180;           }    server {         listen       82;         server_name  localhost;         #charset  koi8-r;         #access_log   logs/host.access.log   main;        location / {             proxy_pass http://webser;              #root    html;              #index   index.html index.htm;         }        error_page   500 502  503 504  /50x.html;        location = /50x.html {             root   html;         }    }}

4. Start the service

Start two server nginx and keepalived services:

[[email protected] ~]# Nginx[[email protected] ~]# service keepalived startredirecting to/bin/systemctl start keepalived . Service

5. View VIP

6. Page Access

vip1:http://172.27.9.200:82/

vip2:http://172.27.18.120:82/

Refresh the Web to discover Vip1 and VIP2 to access the Web server in polling mode, respectively

7. Highly Available tests

With the previous article, no longer repeat.

The test is complete, the cloud Platform production environment can also be implemented according to this test.
