Yesterday we introduced the mobile phone matching rules of haproxy. Today we will introduce the integration of haproxy with nginx and zabbix. Next, I will introduce in detail the integration of haproxy and nginx directory browsing function, and integrate with zabbix, I will post the haproxy configuration.

I. Business Requirements

Due to business requirements, some directories on the server should be exposed to other systems to call exposed files. However, port 80 http service is required for external use.

Analysis:

To meet the above requirements, we first need to provide the directory browsing function. We can use the directory browsing function of apache or nginx. Here, we use the nginx directory browsing function (that is, the nginx directory indexing function ).

Then let haproxy reverse proxy to nginx to achieve business needs.

Ii. nginx Configuration

The installation of nginx is not listed here. Let's look at the nginx configuration file. As follows:

User nginx;

Worker_processes 1;

Error_log/var/log/nginx/error. log warn;

Pid/var/run/nginx. pid;

Events {

Worker_connections 1024;

}

Http {

Include/etc/nginx/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/var/log/nginx/access. log main;

Sendfile on;

Keepalive_timeout 65;

Gzip on;

Server {

Listen 8088;

Server_name 127.0.0.1;

Charset UTF-8;

Access_log/var/log/nginx/log/host. access. log main;

Location/testnginx /{

Root/data /;

Autoindex on;

}

}

}

Nginx is now defined to listen to port 8088, And the directory testnginx under/data is open to the outside world.

Note: This external directory name must be remembered. This name will be used in haproxy matching rules.

After nginx is configured, select to view the directory browsing function. As follows:

Http://http.ilanni.com: 8088/testnginx/

We can see that nginx directory browsing is completely normal.

3. haproxy Configuration

After nginx is configured, configure haproxy. The configuration of haproxy is simple.

You only need to match the directory name in the url requested by the client. The specific configuration file is as follows:

Global

Log 127.0.0.1 local0

Log 127.0.0.1 local1 notice

Maxconn 4096

Uid 188

Gid 188

Backend nginxserver

Server web1 127.0.0.1: 8088 maxconn 1024 weight 3 check inter 2000 rise 2 fall 3

In the haproxy configuration file, we define an is_nginx rule that matches the url starting with the testnginx directory and then forwards the rule to the backend nginxserver server group, the nginxserver server group is the nginx server.

In this way, nginx and haproxy are integrated.

Note: Please note that the directory must exist in the backend server group when haproxy matches the directory. Otherwise, error 1.1 will be reported. This is only known after I step on many pitfalls.

Iv. Test the Integration Function

After nginx and haproxy are integrated and configured, we choose to access http://http.ilanni.com/testnginx/to test their functions, as shown below:

We can see that haproxy has been perfectly integrated with the nginx directory browsing function.

5. Integration of haproxy and zabbix

In the previous sections, we have explained the Integration Functions of haproxy and nginx. In this section, we will introduce the Integration Functions of haproxy and zabbix.

Zabbix is installed using the yum method here. After installation, apache listens to port 8099. The access method is as follows:

Http://zabbix.ilanni.com: 8099/zabbix/

Now we need to directly use port 80 to access zabbix. The specific configuration of haproxy is as follows:

Global

Log 127.0.0.1 local0

Log 127.0.0.1 local1 notice

Maxconn 4096

Uid 188

Gid 188

Haproxy is easy to configure. You only need to define an is_zabbix url matching rule and distribute it to the backend server group.

Note that the matched directory exists on the backend server.

After the configuration is complete, access the following:

Http://zabbix.ilanni.com/zabbix/

We can see that haproxy and zabbix have been perfectly integrated.
