Saltstack Web Platform Cluster Deployment (3)---HAPROXY+KEEPALIVE+HTTPD deployment

Last article we talked about the deployment and configuration of Haproxy

Let's talk about how to use keepalive and httpd to implement the Saltstack cluster deployment of the HAPROXY+KEEPALIVE+HTTPD Web architecture

First of all our HTTP deployment, very simple answer oh, the direct yum installation is complete, but in our saltstack is to use the installed definition of the line.

OK, let's get up.

[email protected] http]# pwd
/srv/salt/prod/http
[email protected] http]# cat Install.sls
Include
-Pkg.pkg-init

Httpd-install:
Pkg.installed:
-Names:
-httpd
-Httpd-devel

It's not very simple, let's get it started underneath.

[[email protected]cluster]# pwd
/srv/salt/prod/cluster
[[email protected]cluster]# Cat Http.sls
Include
-Http.install

Http-service:
File.managed:
-Name:/etc/httpd/conf/httpd.conf
-Source:salt://cluster/files/httpd.conf
-User:root
-Group:root
-mode:644
Service.running:
-NAME:HTTPD
-Enable:true
-Reload:true
-UNLESS:NETSTAT-LNTP |awk-f ': ' {print $4} ' | grep 8080

Let's get the keepalived installation file below.

[[email protected]keepalived]# pwd
/srv/salt/prod/keepalived
[[email protected]keepalived]# Cat Install.sls
Keepalived-install:
File.managed:
-Name:/usr/local/src/keepalived-1.2.17.tar.gz
-Source:salt://keepalived/files/keepalived-1.2.17.tar.gz
-mode:755
-User:root
-Group:root
Cmd.run:
-Name:cd/usr/local/src && tar zxf keepalived-1.2.17.tar.gz && cd keepalived-1.2.17 &&./configu Re--prefix=/usr/local/keepalived--disable-fwmark && make && make install
-Unless:test-d/usr/local/keepalived
-Require:
-File:keepalived-install

/etc/sysconfig/keepalived:
File.managed:
-Source:salt://keepalived/files/keepalived.sysconfig
-mode:644
-User:root
-Group:root

/etc/init.d/keepalived:
File.managed:
-Source:salt://keepalived/files/keepalived.init
-mode:755
-User:root
-Group:root

Keepalived-init:
Cmd.run:
-Name:chkconfig--add keepalived
-Unless:chkconfig--list | grep keepalived
-Require:
-File:/etc/init.d/keepalived

/etc/keepalived:
File.directory:
-User:root
-Group:root

Different people, defined in a different way, but the effect of the implementation is the same. This configuration is a simple answer, it is not described here specifically. There is an installation package in the attachment.

The installation section is complete, let's start the section below. Let's just put it under the cluster directory.

[[email protected]cluster]# pwd
/srv/salt/prod/cluster
[[email protected]cluster]# Cat Haproxy-outside-keepalived.sls # #为了区分是haproxy外网的配置
Include
-Keepalived.install
Keepalived-server:
File.managed:
-Name:/etc/keepalived/keepalived.conf
-Source:salt://cluster/files/haproxy-outside-keepalived.conf
-mode:644
-User:root
-Group:root
-Template:jinja
{% if grains[' fqdn '] = = ' test1 '%}
-Routeid:haproxy_ha
-Stateid:master
-priorityid:150
{% elif grains[' FQDN '] = = ' test2 '%}
-Routeid:haproxy_ha
-Stateid:backup
-priorityid:100
{% ENDIF%}
Service.running:
-Name:keepalived
-Enable:true
-Watch:
-File:keepalived-server

Here we briefly explain, first of all, the use of the Jinja template, using pillar to define the

Below is the configuration file for keepalived

[[email protected]files]# pwd

[[email protected]files]# Cat haproxy-outside-keepalived.conf

And, of course, we add it to top to define it. Then it's done. Deployment of the Web platform cluster.
