第五部分测试验证邮件报警
第一部分实验环境
[*]Linux服务端一台
IP地址：192.168.80.10
需要软件：php-bcmath-5.4.16-42.el7.x86_64
php-mbstring-5.4.16-42.el7.x86_64
注意：需要公网环境（可以上外网），网上下载最新版本的zabbix服务
从微软客户端下载字体（楷体）到本机

第二步：部署zabbix服务
# rpm -ivh php-mbstring-5.4.16-42.el7.x86_64.rpm
# rpm -ivh php-bcmath-5.4.16-42.el7.x86_64.rpm
# rpm -ivh http://repo.zabbix.com/zabbix/3.5/rhel/7/x86_64/zabbix-release-3.5-1.el7.noarch.rpm //网上下载最新版本的zabbix源（自动生成Yum源）
# yum install zabbix-server-mysql zabbix-web-mysql –y //安装zabbix服务及插件
# zcat /usr/share/doc/zabbix-server-mysql-4.0.0/create.sql.gz | mysql -uzabbix -pzabbix //生成数据库文件,注意密码不要输成root的（admin123）
# vi /etc/zabbix/zabbix_server.conf //编辑配置文件
http://i2.运维网.com/images/blog/201804/15/c01188317e6bb0f2b44e03fbcc3d4f11.png
保存退出
# grep -n '^' /etc/zabbix/zabbix_server.conf //过滤查看配置文件
http://i2.运维网.com/images/blog/201804/15/db6055846c66792192af570492f373d2.png
# vi /etc/httpd/conf.d/zabbix.conf //修改时区
http://i2.运维网.com/images/blog/201804/15/ddeec6061a3066fabb8a23f4ba161d45.png
保存退出
# cp stkaiti.ttf /usr/share/zabbix/fonts/
# vi /usr/share/zabbix/include/defines.inc.php //修正图表中文乱码的问题

# netstat -anpt | grep zabbix
http://i2.运维网.com/images/blog/201804/15/3afc804d381e8743b072c178003b00e9.png
# systemctl restart httpd //重启apache服务

http://i2.运维网.com/images/blog/201804/15/8b200157053254eeae0360a48712106d.png
更新后，重新打开网页
http://i2.运维网.com/images/blog/201804/15/eaad8f3d772d13d364e40a0ad08c77f5.png
第三部分配置客户端（被控服务器）
第一步：安装配置zabbix-agent
注意：如果服务器也需要被自己监控也需要安装zabbix-agent
# rpm -ivh http://repo.zabbix.com/zabbix/3.5/rhel/7/x86_64/zabbix-release-3.5-1.el7.noarch.rpm
# yum install -y zabbix-agent
# vi /etc/zabbix/zabbix_agentd.conf //编辑配置文件
修改以下内容：
Server=192.168.80.10
ServerActive=192.168.80.10
Hostname=client
保存退出
# grep -n '^' /etc/zabbix/zabbix_agentd.conf
http://i2.运维网.com/images/blog/201804/15/c135735f30935f0bcffefe68cbb4f354.png
# service firewalld stop
# setenforce 0
# systemctl enable zabbix-agent
# systemctl restart zabbix-agent
# netstat -anpt | grep zabbix
http://i2.运维网.com/images/blog/201804/15/4d83bd32fbce80e54f09b705a9a60cdb.png
第二步：增加被控主机—web平台上操作
http://i2.运维网.com/images/blog/201804/15/26a66cd8f5109ab8d13cd73532c89a94.png
http://i2.运维网.com/images/blog/201804/15/e03f31c1582764cbd2821b93a86a262a.png
保存添加
http://i2.运维网.com/images/blog/201804/15/8b242217062279f95c3f5aa2f46c15b5.png
监控http、ssh，linux本身系统性能，添加后更新
http://i2.运维网.com/images/blog/201804/15/ce69ad37d5e4c03c0b0cda41d9c1c315.png
已成功添加
第四部分配置邮件报警功能
注意：网易邮箱需要开启客户端授权码进行第三方登录
http://i2.运维网.com/images/blog/201804/15/f1c6bda5d6d4d772875408f4e667fb1d.png
授权码设置为：abc123
第一步：服务端配置
//安装mailx，并配置
# yum install –y mailx
# vi /etc/mail.rc
最后添加以下内容：
set from=yxc8703@163.com
set smtp=smtp.163.com
set smtp-auth-user=yxc8703@163.com
set smtp-auth-password=abc123
set smtp-auth=login
保存退出
# echo "tttttttt" | mail -s "testmail" yxc8703@163.com //测试正常发信
查看邮箱：
http://i2.运维网.com/images/blog/201804/15/ddd584ebb641e3087b2c4c00e1cf0278.png
测试正常
# cd /usr/lib/zabbix/alertscripts/
# vi mailx.sh //编写发邮件脚本
#!/bin/bash
#send mail
messages=echo $3 | tr '\r\n' '\n'
subject=echo $2 | tr '\r\n' '\n'
echo "${messages}" | mail -s "${subject}" $1 >>/tmp/mailx.log 2>&1
保存退出
# touch /tmp/mailx.log
# chown -R zabbix.zabbix/tmp/mailx.log
# chmod +x /usr/lib/zabbix/alertscripts/mailx.sh
# chown -R zabbix.zabbix /usr/lib/zabbix/
# ./mailx.sh yxc8703@163.com "主题" "内容" //测试发邮件脚本是否可以正常工作
查看邮箱：

测试成功
第二步：web页面配置
[*]管理—报警媒体类型—创建媒体类型
http://i2.运维网.com/images/blog/201804/15/bb08c0549fb79ee68be07e1eccf380de.png
名称：Mail-Test
类型：脚本
脚本名称：mailx.sh
脚本参数：//新增以下三个参数
{ALERT.SENDTO}
{ALERT.SUBJECT}
{ALERT.MESSAGE}

第五部分测试验证邮件报警
一：服务器与客户端重启zabbix服务
# systemctl restart zabbix-server
# systemctl restart zabbix-agent.service
二：被控端安装http服务，打开sshd服务
# yum install -y httpd
# vi /etc/httpd/conf/httpd.conf
ServerName client
保存退出
# echo "This is test" > /var/www/html/index.html
# systemctl start httpd
# netstat -anpt | grep httpd

三：测试邮件报警
[*]模拟根分区使用率超过80%，测试邮件报警
//zabbix默认磁盘分区使用率超过80%会自动报警，因此不用作任何配置
# df -hT
http://i2.运维网.com/images/blog/201804/15/54df6264e534e83b16108bb3affb413a.png

[*]模拟关闭http、ssh服务
# systemctl stop httpd
# systemctl stop sshd
//查看邮箱
