接上篇博文《SaltStack实践（一）-- 安装配置HAproxy》
1、编写功能模块
#创建keepalived目录 [root@linux-node1 ~]#mkdir -p /srv/salt/prod/keepalived/files [root@linux-node1 ~]#cd /srv/salt/prod/keepalived/files #获取并解压keepalived [root@linux-node1 files]#wget http://www.keepalived.org/software/keepalived-1.2.19.tar.gz [root@linux-node1 files]#tar xf keepalived-1.2.19.tar.gz [root@linux-node1 files]#cd keepalived-1.2.19 #从源码包拷贝启动脚本、配置文件到files目录 [root@linux-node1 keepalived-1.2.19]#cp keepalived/etc/init.d/keepalived.init /srv/salt/prod/keepalived/files/ [root@linux-node1 keepalived-1.2.19]#cp keepalived/etc/init.d/keepalived.sysconfig /srv/salt/prod/keepalived/files/ [root@linux-node1 keepalived-1.2.19]#cp keepalived/etc/keepalived/keepalived.conf /srv/salt/prod/keepalived/files/ #编写install.sls文件 [root@linux-node1 keepalived-1.2.19]# cd /srv/salt/prod/keepalived/ [root@linux-node1 keepalived]# vim install.sls include: - pkg.pkg-init keepalived-install: file.managed: - name: /usr/local/src/keepalived-1.2.19.tar.gz - source: salt://keepalived/files/keepalived-1.2.19.tar.gz - user: root - group: root - mode: 755 cmd.run: - name: cd /usr/local/src && tar xf keepalived-1.2.19.tar.gz && cd keepalived-1.2.19 && ./configure --prefix=/usr/local/keepalived --disable-fwmark && make && make install - unless: test -d /usr/local/keepalived - require: - pkg: pkg-init - file: keepalived-install keepalived-init: file.managed: - name: /etc/init.d/keepalived - source: salt://keepalived/files/keepalived.init - user: root - group: root - mode: 755 cmd.run: - name: chkconfig --add keepalived - unless: chkconfig --list |grep keepalived - require: - file: keepalived-init /etc/sysconfig/keepalived: file.managed: - source: salt://keepalived/files/keepalived.sysconfig - user: root - group: root - mode: 644 /etc/keepalived: file.directory: - user: root - group: root - mode: 755 #测试 [root@linux-node1 keepalived]# salt '*' state.sls keepalived.install env=prod test=True linux-node2.example.com: ---------- ....

2、编写业务模块
[root@linux-node1 keepalived]# cd ../cluster/
#编写keepalived配置文件
[root@linux-node1 cluster]# cd files/
[root@linux-node1 files]# vim 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` # jinja模板变量
}
vrrp_instance haproxy_ha {
state `STATEID` # jinja模板变量
interface eth0
virtual_router_id 36
priority `PRIORITYID` # jinja模板变量
advert_int 1
authentication {
auth_type PASS
auth_pass 1111
}
virtual_ipaddress {
10.0.0.11
}
}
#编写用于管理keepalived配置文件的SLS
[root@linux-node1 files]#cd ..
[root@linux-node1 cluster]# vim haproxy-outside-keepalived.sls
include:
- keepalived.install
keepalived-serivce:
file.managed:
- name: /etc/keepalived/keepalived.conf

- template: jinja
{% if grains['fqdn'] == 'linux-node1.example.com' %}
- ROUTEID: haproxy_ha
- STATEID: MASTER
- PRIORITYID: 150
{% elif grains['fqdn'] == 'linux-node2.example.com' %}
- ROUTEID: haproxy_ha
- STATEID: BACKUP
- PRIORITYID: 100
{% endif %}
service.running:
- name: keepalived

#测试
