操作内容：
一、基础环境
1、使用tvm-cobbler安装一个tvm-zabbix虚拟机来做实验。在“配置zabbix所需的mysql-server”的基础上继续操作
2、网络：
eth0：host-only（用于虚拟内网，手动固定IP，这样从宿主机可以直接连接到这个vm）
eth1：NAT（用于上外网，动态IP）
[root@tvm-zabbix ~]# cd /etc/sysconfig/network-scripts/
[root@tvm-zabbix network-scripts]# cat ifcfg-eth0
DEVICE=eth0
TYPE=Ethernet
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=none
IPADDR=192.168.56.200
PREFIX=24
GATEWAY=192.168.56.1
DNS1=192.168.56.254
[root@tvm-zabbix network-scripts]# cat ifcfg-eth1
DEVICE=eth1
TYPE=Ethernet
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=dhcp
DNS1=192.168.56.254
[root@tvm-zabbix ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda3 36G 1.8G 32G 6% /
tmpfs 499M 12K 499M 1% /dev/shm
/dev/sda1 194M 29M 155M 16% /boot
/dev/sdb1 99G 188M 94G 1% /data
使用域名：
[root@tvm-yum ~]# cat /etc/dnsmasq.d/office.conf |grep zbx-m
address=/zbx-m.office.test/192.168.56.200
3、repo
我们在自己的office这个repo中已经增加了几个rpm包：
[root@tvm-zabbix ~]# yum search --disablerepo='*' --enablerepo='office' zabbix
Loaded plugins: fastestmirror, security
Loading mirror speeds from cached hostfile
======================================================================================= N/S Matched: zabbix ========================================================================================

二、配置
1、文件结构
[root@tvm-saltmaster base]# tree zabbix/
zabbix/
├── agent.sls
├── server.sls
└── web.sls
0 directories, 3 files
[root@tvm-saltmaster base]# tree conf.d/zabbix/

===================================================agent end
3、conf配置
1）README.txt
===================================================README.txt
[root@tvm-saltmaster base]# cat conf.d/zabbix/README.txt
# 简化配置文件：
grep ^[^#] tpl.zabbix_agentd.conf >zabbix_agentd.conf
grep ^[^#] tpl.zabbix_server.conf >zabbix_server.conf
===================================================README.txt end
2）httpd_zabbix.conf
对比默认文件，仅修改了timezone这行：
php_value date.timezone Asia/Shanghai
附上完整的配置：
===================================================httpd_zabbix.conf
[root@tvm-saltmaster base]# cat conf.d/zabbix/httpd_zabbix.conf
#
# Zabbix monitoring system php web frontend
#
Alias /zabbix /usr/share/zabbix
<Directory "/usr/share/zabbix">

<Directory "/usr/share/zabbix/include/classes">
Order deny,allow
Deny from all
<files *.php>
Order deny,allow
Deny from all
</files>
</Directory>
===================================================httpd_zabbix.conf end
3）php_zabbix.ini
和昨天配置mysql时用到的一致。
===================================================php_zabbix.ini end
[root@tvm-saltmaster base]# cat conf.d/zabbix/php_zabbix.ini |grep -E 'timezone|mysql.sock' |grep -v ';'
date.timezone = Asia/Shanghai
mysql.default_socket = /data/mysql/mysql.sock
mysqli.default_socket = /data/mysql/mysql.sock
===================================================php_zabbix.ini end
4）zabbix_agentd.conf
===================================================zabbix_agentd.conf
[root@tvm-saltmaster base]# cat conf.d/zabbix/zabbix_agentd.conf
PidFile=/var/run/zabbix/zabbix_agentd.pid
LogFile=/var/log/zabbix/zabbix_agentd.log
LogFileSize=5
Server=zbx-m.office.test
ListenIP={{ grains['ip_interfaces']['eth0'][0] }}
ServerActive=zbx-m.office.test
Hostname={{ grains['id'] }}
Include=/etc/zabbix/zabbix_agentd.d/
UnsafeUserParameters=1
===================================================zabbix_agentd.conf end
5）zabbix_server.conf
===================================================zabbix_server.conf
[root@tvm-saltmaster base]# cat conf.d/zabbix/zabbix_server.conf
LogFile=/var/log/zabbix/zabbix_server.log
LogFileSize=10
PidFile=/var/run/zabbix/zabbix_server.pid
DBHost=localhost
DBName=zabbix
DBUser=zabbix
DBPassword=zabbix
DBSocket=/data/mysql/mysql.sock
DBPort=3306
SNMPTrapperFile=/var/log/snmptt/snmptt.log
AlertScriptsPath=/usr/lib/zabbix/alertscripts
ExternalScripts=/usr/lib/zabbix/externalscripts
===================================================zabbix_server.conf end
三、执行
[root@tvm-saltmaster base]# salt 'tvm-zabbix' state.sls zabbix.server --output-file='/tmp/z1.log'
[root@tvm-saltmaster base]# salt 'tvm-zabbix' state.sls zabbix.web --output-file='/tmp/z2.log'
[root@tvm-saltmaster base]# salt 'tvm-zabbix' state.sls zabbix.agent --output-file='/tmp/z3.log'
四、配置zabbix-web
1、访问：
http://192.168.56.200/zabbix
根据引导一步步操作，然后登录web页面。
2、我们来使用下“Active agent auto-registration”的功能
1）configuration-action页面，找到右上方“Create action”下面有个下拉框“Event Source”，选择：“Auto registration”
2）点击“Create action”创建一个动作
3）在“Action”选项卡输入一个“Name”：test auto registration
4）在“Conditions”选项卡新增一个条件：Host name like tvm
5）在“Operations”选项卡新增操作：
Add to host groups: Linux servers
Link to templates: Template OS Linux
保存。
3、配置zabbix-web报警
1）脚本（调用在“saltstack的深入-管理python-pip”这篇提到的发送邮件的脚本：sendEmail）
[root@tvm-zabbix ~]# cat /usr/lib/zabbix/alertscripts/mailman.sh
#!/bin/bash
#
# 2015/8/18
export LANG="en_US.UTF-8"
echo -e "`date +%F' '%T` \n$1 $2 $3 \n\n" >>/var/log/zabbix/mail_send.log
/usr/bin/sendEmail -o message- \
-s smtp.xxx.com \
-xu username \
-xp password \
-f from@company.com \
-t "$1" \
-u "$2" \
-m "$3" >>/var/log/zabbix/mail_detail.log 2>&1 &
[root@tvm-zabbix ~]# chown zabbix:zabbix /usr/lib/zabbix/alertscripts/mailman.sh \
&& chmod 700 /usr/lib/zabbix/alertscripts/mailman.sh \
&& ls -l /usr/lib/zabbix/alertscripts/mailman.sh
-rwx------ 1 zabbix zabbix 240 Aug 18 17:08 /usr/lib/zabbix/alertscripts/mailman.sh
2）在web上操作：增加Media types
Administrator-Media types-Email
选择
Type: Script
Script name: mailman.sh
3）在web上操作：给用户增加media
Administrator-Users-user-Media
新增一个邮箱。
4）增加action
1）configuration-action页面，找到右上方“Create action”下面有个下拉框“Event Source”，选择：“Triggers”
2）创建一个，注意operations中增加操作时，
Operation type: Send message
Send to Users: 选择用户
Send only to: Email
测试符合预期。
五、Q&A
【Q】：当某个主机的hostname被更改后，此时salt通过grains获取的id会变化吗？如果会，多久才产生变化呢？对zabbix-agent的配置管理和zabbix-agent的自动注册如何改进？
A：使用{{ grains['id'] }}来取minion的值，而不是fqdn或host，这样得到的值不会产生变化，除非这个minion的配置做了变更。
