|NO.Z.00044|——————————|^^ 构建 ^^|——|Zabbix3.2构建.V5|——|2台server|

附录一：构建zabbix监控服务器

一、初始化系统设置

### --- 初始化系统设置

systemctl stop firewalld
systemctl disable firewalld
setenforce 0
sed -i "s/SELINUX=enforcing/SELINUX=disabled/g" /etc/selinux/config

二、安装LAMP环境

### --- 安装LAMP环境
wget http://mirros.163.com/./help/CentOS7-Base-163.repo
yum clean all
yum makecache
yum install -y mariadb mariadb-server httpd php php-mysql 

systemctl enable httpd
systemctl restart httpd
systemctl enable mariadb
systemctl restart mariadb
mysql_secure_installation

三、安装zabbix程序

### --- 安装zabbix程序
rpm -ivh http://repo.zabbix.com/zabbix/3.2/rhel/7/x86_64/zabbix-release-3.2-1.3l7.noarch.rpm
rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX 
yum install -y zabbix-server-mysql zabbix-web-mysql zabbix-agent

### --- 初始化数据库：
mysql -u root -p 
CREATE DATABASE zabbix DEFAULT CHARACTET SET utf8 COLLATE utf8_bin;
grant all privileges on zabbix.* to zabbix@localhost identified by'zabbix';

### --- 读入数据库
cd /usr/share/doc/zabbix-server-mysql-3.2.1
zcat creat.sql.gz |mysql -uroot -p zabbix

### --- 启动zabbix服务
vim /etc/zabbix/zabbix_server.conf
    DBHost=localhost
    DBName=zabbix
    DBUser=zabbix
    DBPassword=zabbix
systemctl start zabbix-server
systemctl enable zabbix-server

### --- 编辑zabbix前端PHP配置

vim /etc/httpd/conf.d/zabbix.conf
    php_value max_execution_time 300
    php_value memory_limit 128M
    php_value upload_max_filesize 2M 
    php_value max_input_time 300
    php_value always_populate_raw_post_data -l
    php_value date.timezone Asia/Shanghai

### --- 调整时间同步
yum install -y ntpdate
ntpdate cn.pool.ntp.org

### --- 重启Apache服务生效
systemctl restart httpd

四、修改中文乱码问题

### --- wind+R > fonts > 拷贝微软雅黑字体改名为msyh.ttf > /usr/share/zabbix/fonts
vim /usr/share/zabbix/include/defines.inc.php

### --- 修改zabbix php 页面配置，将'graohfont'修改为msyh
dnfine('ZBX_GRAPH_FONT_NAME','msyh');

五、添加客户端

### --- 添加客户端

vim /usr/local/zabbix/etc/zabbix_agentd.configure
LogFile=/tmp/zabbix_agentd.log
Server= 192.168.1.195
ServerActive = 192.168.1.195
Hostname = 192.168.1.195
rpm -ivh http://repo.zabbix.com/zabbix/3.2/rhel/6/x86_64/zabbix-release-3.2-1.el6.noarch.rpm

---

六、添加监控主机/自动发现,nginx并发监控

### --- 添加监控主机
### --- 源码编译安装Nginx服务器并开启状态统计模块
### --- zabbix客户端配置
### --- 编写nginx监控脚本，在被监控端

#!/bin/bash

HOST="127.0.0.1"
PORT="80"

#检测nginx进程是否存在
function ping {
        /sbin/pidof nginx | wc -l
}
#检测nginx性能
function active {
    /usr/bin/curl "http://$HOST:$PORT/nginx-status/" 2>/dev/null| grep 'Active' | awk '{print $NF}'
}
function reading {
    /usr/bin/curl "http://$HOST:$PORT/nginx-status/"  2>/dev/null| grep 'Reading' | awk '{print $2}'
}
function writing {
    /usr/bin/curl "http://$HOST:$PORT/nginx-status/" 2>/dev/null| grep 'Writing' | awk '{print $4}'
}
function waiting {
    /usr/bin/curl "http://$HOST:#PORT/nginx-status/" 2>/dev/null| grep 'Waiting' | awk' {print $6}'
}
function accepts {
    /usr/bin/curl "http://$HOST:$PORT/nginx-status/" 2>/dev/null| awk NR==3 | awk '{print$1}'
}
function handled {
    /usr/bin/curl "http://$HOST:$PORT/nginx-status/" 2>/dev/null| awk NR==3 | awk '{print $2}'
}
function requests {
    /usr/bin/curl "http://$HOST:$PORT/nginx-status/" 2>/dev/null| awk NR==3 | awk '{print $3}'
}
#执行function
$1

### --- 将自定义的UserParameter加入配置文件，然后重启agentd

cat /usr/local/zabbi-3.0.0/etc/zabbix_agentd.conf|grep nginx
UserParameter=naginx.status[*],/usr/local/zabbix-3.0.0/scropts/ngx-status.sh $1

~~~     killall zabbix_agentd
~~~     usr/local/zabbix-3.0.0/sbin/zabbix_agentd

### --- zabbix_get获取数据
/usr/local/zabbix-3.0.0/bin/zabbix_get -s 10.10.1.121 -k 'nginx.status[accepts]'
                                9570756
/usr/local/zabbix-3.0.0/bin/zabbix_get -s 10.10.1.121 -k 'nginx.status[ping]'

---

七、报警设置：zabbix 联合钉钉实现终端报警

1、监控方式添加参数

{ALERT.SENDTO}
{ALERT.SUBJECT}
{ALERT.MESSAGE}

2、错误报警信息参数

### --- 标题改为
故障{ERIGGER.STATUS},服务器：{HOSTNAME1}发生：
{TRIGGER.NAME}故障
### --- 信息改为
告警主机：{HOSTNAME1}
告警时间：{EVENT.DATE}{EVENT.TIME}
告警等级：{TRIGGER.SEVERITY}
告警信息：{TRIGGER.NAME}
告警项目：{TRIGGER.KEY1}
问题详情：{ITEM.NAME}:{ITEM.VALUE}
当前状态：{TRIGGER.STATUS}:{ITEM.VALUE1}
事件ID：{EVENT.ID}

3、错误恢复报警信息设置

### --- 标题改为
恢复{TRIGGER.STATUS},服务器：{HOSTNAME1}：
{TRIGGER.NAME}故障
### --- 信息改为
告警主机：{HOSTNAME1}
告警时间：{EVENT.DATE}{EVENT.TIME}
告警等级：{TRIGGER.SEVERITY}
告警信息：{TRIGGER.NAME}
告警项目：{TRIGGER.KEY1}
问题详情：{ITEM.NAME}:{ITEM.VALUE}
当前状态：{TRIGGER.STATUS}:{ITEM.VALUE1}
事件ID：{EVENT.ID}
