saltstack 的web平台集群部署（3）---haproxy+keepalive+httpd 的部署

x625802392

　　上一篇文章咱们讲到了haproxy的部署与配置
　　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。
　　[root@test1 http]# pwd
　　/srv/salt/prod/http
　　[root@test1 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。
　　[root@test1 cluster]# pwd
　　/srv/salt/prod/cluster
　　[root@test1 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。
　　[root@test1 keepalived]# pwd
　　/srv/salt/prod/keepalived
　　[root@test1 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
　　[root@test1 cluster]# pwd
　　/srv/salt/prod/cluster
　　[root@test1 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
　　[root@test1 files]# pwd
　　/srv/salt/prod/cluster/files
　　[root@test1 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。
　　[root@test1 base]# pwd
　　/srv/salt/base
　　[root@test1 base]# cat top.sls
　　base:
　　'*':
　　- init.env_init
　　prod:
　　'test[1,2]':
　　- cluster.haproxy-outside-keepalived
　　- cluster.haproxy-outside
　　- cluster.http
　　[root@test1 base]# salt '*' state.highstate test=true
