saltstack实战4--综合练习3
Saltstack配置管理-业务引用haproxy
在业务模块里写它的配置
各个业务是不同的，这里有差异性，所以没写在配置模块里。
对minion02也执行安装haproxy
[root@master ~]# salt 'minion02' state.sls haproxy.install env=prod
关于系统初始化部分和haproxy安装部分，所有minion都是相同的。而业务这块因前期规划不同，配置有差异。
我们把因为业务差异的这部分单独拿出来。单独配置
创建目录，编辑haproxy的配置文件
[root@master ~]# mkdir /srv/salt/prod/cluster
[root@master ~]# mkdir /srv/salt/prod/cluster/files
[root@master ~]# cd /srv/salt/prod/cluster/files/
[root@master files]# vim haproxy-outside.cfg
[root@master files]# cat haproxy-outside.cfg
global

[root@master files]#
编辑haproxy的业务状态文件
监控haproxy-service这个id下面的file模块，文件发生改变就reload
[root@master files]# cd ..
[root@master cluster]# pwd
/srv/salt/prod/cluster
[root@master cluster]# vim haproxy-outside.sls
[root@master cluster]# cat haproxy-outside.sls
include:
- haproxy.install haproxy-service:
file.managed:
- name: /etc/haproxy/haproxy.cfg
- source: salt://cluster/files/haproxy-outside.cfg
- user: root
- group: root
- mode: 644
service.running:
- name: haproxy
- enable: True
- reload: True
- require:
- cmd: haproxy-init
- watch:
- file: haproxy-service
[root@master cluster]#
这次我们想通过top.sls执行
[root@master base]# pwd
/srv/salt/base
[root@master base]# cat top.sls
base:
'*':
- init.env_init prod:
'minion01':
- cluster.haproxy-outside
'minion02':
- cluster.haproxy-outside
[root@master base]#
在执行状态文件直线，先对两台minion的apache端口进行更改
通过cmd.run模块方法，结合grep和sed命令远程更改文件
[root@master base]# salt 'minion01' cmd.run 'grep Listen /etc/httpd/conf/httpd.conf' minion01:
# Listen: Allows you to bind Apache to specific IP addresses and/or
# Change this to Listen on specific IP addresses as shown below to
#Listen 12.34.56.78:80
Listen 80
[root@master base]# salt 'minion01' cmd.run 'grep '^Listen' /etc/httpd/conf/httpd.conf'
minion01:
Listen 80
[root@master base]# salt 'minion01' cmd.run "sed -i 's#Listen 80#Listen 8080#g' /etc/httpd/conf/httpd.conf"
minion01:
[root@master base]# salt 'minion01' cmd.run 'grep Listen /etc/httpd/conf/httpd.conf'
minion01:
# Listen: Allows you to bind Apache to specific IP addresses and/or
# Change this to Listen on specific IP addresses as shown below to
#Listen 12.34.56.78:80
Listen 8080
[root@master base]# salt 'minion02' cmd.run "sed -i 's#Listen 80#Listen 8080#g' /etc/httpd/conf/httpd.conf"
minion02:
[root@master base]# salt 'minion02' cmd.run 'grep Listen /etc/httpd/conf/httpd.conf'
minion02:
# Listen: Allows you to bind Apache to specific IP addresses and/or
# Change this to Listen on specific IP addresses as shown below to
#Listen 12.34.56.78:80
Listen 8080
[root@master base]#
重启两台minion的apache服务
通过service.restart模块操作
[root@master base]# salt '*' service.restart 'httpd'
minion01:
True
minion02:
True
[root@master base]# salt '*' cmd.run 'lsof -i:8080'
minion01:
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME

如果能显示haproxy页面即可，下面显示backend是down的状态是因为后端的apache没设置默认主页
分别设置minion01和minion02 的首页
[root@minion01 ~]# echo minion01-ip-10.0.1.172>>/var/www/html/index.html
[root@minion01 ~]#
minion02的
[root@minion02 ~]# echo minion02-ip-10.0.1.173>>/var/www/html/index.html
[root@minion02 ~]#
再次刷新页面即可
至此，haproxy的业务部分也结束了。
配置keepalived
我们也把它分解下
系统初始化（前期配置haproxy之前已经做过了）
功能模块
业务模块
功能模块部分
采集安装命令
tar xfz keepalived-1.2.19.tar.gz && cd keepalived-1.2.19 && ./configure --prefix=/usr/local/keepalived --disable-fwmark && make && make install
采集文件
启动脚本和keepalived的配置文件需要修改，这两个文件单独取出来
[root@master etc]# pwd
/usr/local/src/keepalived-1.2.19/keepalived/etc
[root@master etc]# ls
init.d keepalived
[root@master etc]# cp init.d/keepalived.init /srv/salt/prod/keepalived/files/
[root@master etc]# cp keepalived/keepalived.conf /srv/salt/prod/keepalived/files/
[root@master etc]# cd /srv/salt/prod/keepalived/files/
[root@master files]#
编辑文件
改成下面内容，只有启动这里需要
daemon /usr/local/keepalived/sbin/keepalived ${KEEPALIVED_OPTIONS}
下面文件也要取出来，从安装后keepalived的目录取出来
[root@mysql keepalived-1.2.19]# cd /usr/local/keepalived/etc/sysconfig/
[root@mysql sysconfig]# ls
keepalived
文件采集3个

[root@master keepalived]# salt '*' state.sls keepalived.install env=prod
keepalived的安装过程至此结束
接下来是业务模块的部分
install.sls里面并没有写配置文件差异的东西，纯安装类的，接下来业务的引用
编辑keepalived的配置文件。 为了方便理解这个文件配合谁用的，命名文件名时如下命名
这里咱们简单的说明一下，首先这里使用了jinja模板的方式，配合sls文件里的pillar
10.0.1.111是虚拟IP
[root@master keepalived]# cd /srv/salt/prod/cluster/files/
[root@master files]# ls
haproxy-outside.cfg
[root@master files]# vim haproxy-outside-keepalived.conf

global_defs {

virtual_router_id 36

advert_int 1
authentication {

auth_pass 1111
}
virtual_ipaddress {
10.0.1.111
}
}

[root@master cluster]# salt 'minion01' state.sls cluster.haproxy-outside-keepalived env=prod
其余minion机器（也就一个minion02了），通过top.sls执行
[root@master base]# cd /srv/salt/base/
[root@master base]# cat top.sls
base:
'*':
- init.env_init prod:
'minion01':
- cluster.haproxy-outside
- cluster.haproxy-outside-keepalived
'minion02':
- cluster.haproxy-outside
- cluster.haproxy-outside-keepalived
[root@master base]#
查看下目录，再次确认都没啥问题，然后执行
[root@master prod]# tree

[root@master prod]# salt '*' state.highstate
最后确认下minion上vip是否已经有一个在启动状态
[root@master prod]# salt '*' cmd.run 'ip addr | grep 10.0.1'
minion01:
inet 10.0.1.172/24 brd 10.0.1.255 scope global eth0
inet 10.0.1.111/32 scope global eth0
minion02:
inet 10.0.1.173/24 brd 10.0.1.255 scope global eth0
[root@master prod]#
停止minion01的keepalived服务，vip也能立马飘到minion02上
[root@master prod]# salt 'minion01' service.stop 'keepalived'
minion01:
True
[root@master prod]# salt '*' cmd.run 'ip addr | grep 10.0.1'
minion01:
inet 10.0.1.172/24 brd 10.0.1.255 scope global eth0
minion02:
inet 10.0.1.173/24 brd 10.0.1.255 scope global eth0
inet 10.0.1.111/32 scope global eth0
[root@master prod]#
启动minion01的keepalived，vip又飘过来
[root@master prod]# salt 'minion01' service.start 'keepalived'
minion01:
True
[root@master prod]# salt '*' cmd.run 'ip addr | grep 10.0.1'
minion01:
inet 10.0.1.172/24 brd 10.0.1.255 scope global eth0
inet 10.0.1.111/32 scope global eth0
minion02:
inet 10.0.1.173/24 brd 10.0.1.255 scope global eth0
[root@master prod]#
浏览器测试，输入vip，访问正常，关于一个源地址访问，总是分配到一个固定的minion，原因在于haproxy的balance配置，这里我们写的是source
如果改成roundrobin，就会随机了
至此，haproxy和keepalived讲解完毕
