zabbix4.0构建实录

【Nginx】

#wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo

[root@centos ~]# yum -y install zlib pcre pcre-devel openssl openssl-devel
[root@centos ~]# useradd -s /sbin/nologin nginx

[root@zabbix-server ~]# yum install -y nginx

【Mysql数据库部署】

# wget https://repo.mysql.com/mysql57-community-release-el7.rpm

# rpm -ivh mysql57-community-release-el7.rpm

[root@zabbix-server ~]# yum install mysql-server mysql mysql-devel

[root@zabbix-server ~]# systemctl start mysqld
[root@zabbix-server ~]# grep "password" /var/log/mysqld.log 
2018-10-23T00:47:33.152924Z 1 [Note] A temporary password is generated for root@localhost: 3e/=lUA;7#+B

mysql> alter user user() identified by '123456.Bxy';
Query OK, 0 rows affected (0.00 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

【注意】

如果不更改密码的话，无法执行任何sql语句，会报错如下：同时要满足密码策略，如果非要修改简单的密码，可以对策略进行修改：

mysql> use mysql;
ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.

mysql> alter user user() identified by '123456.Bxy';   #注意，授权root密码必须要满足四种不同字符：否则修改失败~
Query OK, 0 rows affected (0.00 sec)


现在想要将密码策略修改一下，密码长度改成六位数；密码复杂度不要那么复杂，直接修改成123456即可

首先要修改set global validate_password_policy=0

第二要修改密码长度为6

set global validate_password_length=6;

【php安装】

#yum -y install libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel curl curl-devel openssl openssl-devel openldap openldap-devel

# wget http://soft.y100edu.net/php/php-7.2.11.tar.gz

[root@zabbix-server php-7.2.11]# /etc/init.d/php-fpm start 

整合lnmp环境

[root@zabbix-server conf]# egrep -v "#|^$" /etc/nginx/nginx.conf
worker_processes  1;
events {
    worker_connections  1024;
}
http {

        server_name  localhost;
        location / {
            root   /var/www/html/;
            index index.php index.html index.htm;
        }
           location ~ .php$ {

        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
    }
}

[root@zabbix-server php-7.2.11]# mkdir -p /var/www/html/

[root@zabbix-server php-7.2.11]# cat /var/www/html/index.php
<?php
phpinfo();
?>

重启Nginx，测试php页面是否整合成功~

[Zabbix部署]

[root@zabbix-server ~]# yum -y install net-snmp net-snmp-devel curl curl-devel libxml2 libevent libevent-devel 

[root@zabbix-server ~]# tar zxvf zabbix-4.0.1.tar.gz -C /usr/src/

[root@zabbix-server ~]# cd /usr/src/zabbix-4.0.1/

[root@zabbix-server zabbix-4.0.1]# ./configure --prefix=/usr/local/zabbix --enable-agent --enable-server --with-libcurl --with-mysql --with-net-snmp --enable-proxy --with-libxml2

[root@zabbix-server zabbix-4.0.1]# make 

[root@zabbix-server zabbix-4.0.1]# make install

[root@zabbix-server conf]# ln -s /usr/local/zabbix/sbin/zabbix_server /usr/local/sbin/

[root@zabbix-server zabbix-4.0.1]# useradd -M -s /sbin/nologin zabbix

LogFile=/var/log/zabbix/zabbix_server.log     #zabbix server日志输出位置
DBHost=localhost     #指定数据库地址，如果数据库在本机，默认即可
DBName=zabbixDB      #数据库名称
DBUser=zabbix        #连接数据库用户名称
DBPassword=123456.Bxy     #连接数据库对应的用户密码
StartPollers=5          #用于设置zabbix服务启动pollers（主动收集数据进程数），数值越大，则服务器吞吐量越大，但是对系统资源消耗很大
StartTrappers=5          #用于设置zabbix server启动时启动Trappers（负责处理agent推送过来的数据进程数量），Agent为主动模式时，该值需要设置大一些
StartDiscoverers=10       #用于设置zabbix server服务启动时启动的Discovers（发现）进程数量，如果discoveres进程忙时，需要提高数值
ListenIP=0.0.0.0       
Timeout=4
AlertScriptsPath=/usr/local/zabbix/share/zabbix/alertscripts    #存放zabbix server运行脚本
LogSlowQueries=3000    

 创建zabbx数据库和授权用户

mysql> create database zabbixDB charset=utf8;
Query OK, 1 row affected (0.01 sec)

mysql> grant all privileges on zabbixDB.* to zabbix@'localhost' identified by '123.com';
Query OK, 0 rows affected, 1 warning (0.06 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

导入zabbix表信息

[root@zabbix_server mysql]# mysql -uzabbix -p123.com  zabbixDB < schema.sql 
[root@zabbix_server mysql]# mysql -uzabbix -p123.com zabbixDB < images.sql 
[root@zabbix_server mysql]# mysql -uzabbix -p123.com zabbixDB < data.sql 

[root@zabbix-server html]# cp -a /usr/src/zabbix-4.0.1/frontends/php/*  /var/www/html/

[root@zabbix-server mysql]# cp /usr/src/zabbix-4.0.1/misc/init.d/tru64/zabbix_* /etc/init.d/
[root@zabbix-server mysql]# chmod +x /etc/init.d/ -R

[root@zabbix-server mysql]# /etc/init.d/zabbix_server start

[root@zabbix-server ~]# cd /var/www/html/conf/

[root@zabbix-server conf]# mv zabbix.conf_(3).php zabbix.conf.php

【部署zabbix agent】

#wget    http://repo.zabbix.com/zabbix/3.4/rhel/7/x86_64/zabbix-agent-3.4.11-1.el7.x86_64.rpm

rpm -ivh zabbix-agent-3.4.11-1.el7.x86_64.rpm

[root@zabbix-server conf]# egrep -v "#|^$" /usr/local/zabbix/etc/zabbix_agentd.conf
LogFile=/var/log/zabbix/zabbix_agentd.log
Server=192.168.37.138
StartAgents=3       #启动agent进程数量，默认三个，如果设置为0，则表示关闭agent被动模式（也就是zabbix server主动来获取agent数据）
ServerActive=192.168.37.138      #启动agent主动模式（agent端主动向zabbix server 推送数据）agent将主动收集到的数据发送到zabbix server端
Hostname=192.168.37.138
Include=/etc/zabbix/zabbix_agent.d/      
UnsafeUserParameters=1     #启动agent端自定义item功能

 systemctl start zabbix-agent

-s指定zabbix-agent端口地址，-p指定agent监听端口，-k表示监控项，也就是item，如果有数据表示zabbix server可以从agent获取数据配置成功~

# /usr/local/zabbix/bin/zabbix_get -s 192.168.37.138 -p 10050 -k "system.uptime"
