zabbix 在linux上安装以及一些配置

　　本文章将演示zabbix 3.2版本的安装，供有需要的伙伴们参考：

网络也有很多关于zabbix的安装文档，甚至每一步的配置都有详细的截图，我这里就不演示截图了，多配置几次自然就熟练了。多折腾。

楼主也是安装过很多次，也安装过很多版本，每次都会遇到一点问题，还不一样，都可以通过网络上搜索解决。

--环境准备

\KRelease (Trial)

# yum -y install lrzsz
# groupadd zabbix
# useradd -d /home/zabbix -g zabbix -m zabbix
# passwd zabbix

--安装相关依赖包

# yum -y install wget unzip libxml2 libxml2-devel httpd php php-mysql php-common php-mbstring php-gd php-odbc \

--可能会遇到一些错误，都可以在网络上进行搜索解决

--configure: error: Invalid Net-SNMP directory - unable to find net-snmp-config
yum install -y net-snmp-devel

--configure: error: no acceptable C compiler found in $PATH
--yum install -y gcc

--server mysql的配置

mysql> grant all privileges on *.* to 'zabbix'@'127.0.0.1' identified by '*';
mysql> use zabbix;
mysql> source /data/soft/zabbix-3.2.7/database/mysql/schema.sql

--zabbix 中文配置

1、确认zabbix是否开启了中文支持功能（/var/www/html/zabbix/include/locales.inc.php）
vim /var/www/html/zabbix/include/locales.inc.php
###'zh_CN' => ['name' => _('Chinese (zh_CN)'), 'display' => true]
2 登录zabbix后,设置用户profile，设置语言为中文，然后点击Update
3 其他也乱码
--这个问题是zabbix web端没有中文库导致
从window-->控制面板-->字体-->选择一种中文字库例如“楷体”，将其拷贝到zabbix服务器上即可
将我们选择的字体文件上传到zabbix web服务，/var/www/html/zabbix/fonts目录下
修改此/var/www/html/zabbix/include/defines.inc.php文件中字体的配置，将里面关于字体设置从DejaVuSans替换成stsong
vim /var/www/html/zabbix/include/defines.inc.php
:%s/DejaVuSans/stsong/g

--Zabbix server 基本配置

zabbix的告警流程
host goups(设备组)--hosts(设备)--applications(监控项组)--
items(监控项)--triggers(触发器)--actions(告警动作)--medias(
告警方式)--user groups(用户组)--users（用户）
1 trigger
configureation--host/template--triggers--create trigger on {HOST.NAME}
2 actions
configureation--actions
--event source-create action
--action--name=send_email_to_user
--recovery message=1
--enabled=1
--conditions--type of calculation= and/or
--conditions=host group/trigger name
--trigger value=problem 任何问题都会发送消息
--maintenance status=not in maintenance在维护时间段内将不发送消息
--operations--send message
--send to user groups =dba
--send to users=txyyhq
--send only to=sendmail
Default operation step duration 为60秒
Steps 为3,表示触发3次动作 1-5-1200
Send to User groups 选择Zabbix administrators
Send to Users 选择 Admin (Zabbix Administrator)
Send only to 选择 sendmail.sh
--recovery operation

3 media Administration-> Media types -> Create mediatype ->
--administration--media type
--create media type
--name=sendmail
--type=script
--script name=sendemail.sh
--Script parameters----3.2 需要自己添加3个参数,
{ALERT.SENDTO}收件人地址
{ALERT.SUBJECT}主题
{ALERT.MESSAGE}详细内容
在users里面添加，Administration –> Users-> Create user -> Media ->Add

--administration--user--create user
4 events
--monitoring--events
--administration--audit

vim /usr/local/zabbix/lib/alertscripts/sendemail.sh $1 $2 $3 ###3个参数
./sendemail.sh *@163.com 1111 hello
$1 收件人 user--media中的send to
$2 为actions中配置的默认主题
$3 为actions中默认的配置消息
##monitoring--triggers 看已发生故障
##查看日志administration--audit--actions
---Admin (Zabbix Administrator) sendmail Sent
[zabbix@hqmysql1 alertscripts]$ ./sendemail.sh *@163.com 1111 hellotest
Jul 19 01:56:24 hqmysql1 sendEmail[3551]: ERROR => Connection attempt to smtp.163.com:25 failed: IO::Socket::INET: Bad hostname 'smtp.163.com'
