saltstack 的web平台集群部署（3）---haproxy+keepalive+httpd 的部署
咱们这里说说如何使用keepalive和httpd来实现haproxy+keepalive+httpd这套web架构的saltstack集群部署首先咱们 http的部署，很简答哦，直接yum安装就完成了，但是在咱们saltstack就是用installed定义就行了。
ok，让咱们搞起。
# pwd
/srv/salt/prod/http
# cat install.sls
include:
- pkg.pkg-init
httpd-install:
pkg.installed:
- names:
- httpd
- httpd-devel
是不是很简单，那咱们下边弄它的启动。
# pwd
/srv/salt/prod/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
下边咱们弄keepalived的安装文件。
# pwd
/srv/salt/prod/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 && ./configure --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
不同的人，定义的方式不同，但是实现的效果是一样的。这个配置很简答，就不在这里具体描述了。附件里有安装包。
安装部分完成了，咱们下边就弄启动部分。咱们还是放到cluster目录下边
# pwd
/srv/salt/prod/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
这里咱们简单的说明一下，首先这里使用了jinja模板的方式，用pillar来定义了
下边是keepalived的配置文件
# pwd
/srv/salt/prod/cluster/files
# cat haproxy-outside-keepalived.conf
! Configuration File for keepalived
global_defs {
notification_email {
saltstack@example.com
}
notification_email_from keepalived@example.com
smtp_server 127.0.0.1
smtp_connect_timeout 30
router_id {{ROUTEID}}
}
vrrp_instance haproxy_ha {
state {{STATEID}}
interface eth0
virtual_router_id 36
priority {{PRIORITYID}}
advert_int 1
authentication {
auth_type PASS
auth_pass 1111
}
virtual_ipaddress {
10.0.0.11
}
}
执行salt '*' state.sls cluster.haproxy-outside-keepalived env=prod test=true
当然最后咱们加到top里边进行定义。那就完成了。对web平台集群的部署。
# pwd
/srv/salt/base
# cat top.sls
base:
'*':
- init.env_init
prod:
'test':
- cluster.haproxy-outside-keepalived
- cluster.haproxy-outside
- cluster.http
# salt '*' state.highstate test=true
