6. 部署Zabbix监控

6.1  安装mysql

[root@ubuntu ~]#hostnamectl set-hostname mysql-master;exit

[root@mysql-master ~]# apt install -y mysql-server

#配置mysql,不然后面登不进mysql

[root@mysql-master ~]# vim /etc/mysql/mysql.conf.d/mysqld.cnf

bind-address        = 0.0.0.0

#重启并开机启动

[root@mysql-master ~]# systemctl restart mysql

[root@mysql-master ~]# systemctl enable --now mysql

#mysql 进入数据库创建账户并授权

[root@mysql-master ~]# mysql

mysql> create database zabbix_server character set utf8 collate utf8_bin;

mysql> grant all privileges on zabbix_server.* to zabbix@'172.31.%.%' identified by 'Mmagedu0!';

mysql> flush privileges;

mysql> quit

6.2  zabbix-server配置

下载安装zabbix

#下载zabbix源

[root@zabbix-server ~]#

wget https://repo.zabbix.com/zabbix/4.0/ubuntu/pool/main/z/zabbix-release/zabbix-release_4.0-3+bionic_all.deb

#安装zabbix源

[root@zabbix-server ~]# dpkg -i zabbix-release_4.0-3+bionic_all.deb

[root@zabbix-server ~]# apt update

#安装Zabbix server，Web前端，agent

[root@zabbix-server ~]# apt install zabbix-server-mysql zabbix-frontend-php zabbix-agent

在zabbix server上初始化数据库

# 测试zabbix用户登录数据库

[root@zabbix-server ~]# mysql -uzabbix -p'Mmagedu0!' -h 172.31.0.104

*************************************************************

查看源安装的一个数据库初始化包不存在

[root@zabbix-server ~]#ls /usr/share/doc/zabbix-server-mysql/

changelog.Debian.gz  copyright  NEWS.Debian.gz  README.Debian

原因是装完zabbix后又装了其他软件，把它给刷新不见了，方法是重新按顺序装一遍

*************************************************************

看到源安装的一个数据库初始化包create.sql.gz

[root@zabbix-server ~]#ls /usr/share/doc/zabbix-server-mysql/

changelog.Debian.gz  copyright  create.sql.gz

生成zabbix数据库：（在zabbix-server上）

[root@zabbix-server ~]# zcat /usr/share/doc/zabbix-server-mysql/create.sql.gz | mysql -uzabbix -p'Mmagedu0!' -h172.31.0.104 zabbix_server

再次进入数据库查看是否有多出zabbix相关的表

[root@zabbix-server ~]#mysql -uzabbix -p'Mmagedu0!' -h172.31.0.104

......

mysql> show databases;

+--------------------+

| Database           |

+--------------------+

| information_schema |

| zabbix_server      |

+--------------------+

2 rows in set (0.00 sec)

mysql> use zabbix_server

mysql> show tables;

+----------------------------+

| Tables_in_zabbix_server    |

+----------------------------+

| acknowledges               |

| actions                    |

| alerts                     |

| application_discovery      |

修改zabbix-server的配置文件

[root@zabbix-server ~]# vim /etc/zabbix/zabbix_server.conf

DBHost=172.31.0.104

DBName=zabbix_server

DBUser=zabbix

DBPassword=Mmagedu0!

DBPort=3306

修改php配置文件的时区

[root@zabbix-server ~]#vim /etc/zabbix/apache.conf

php_value date.timezone Asia/Shanghai

重启服务

[root@zabbix-server ~]# systemctl restart zabbix-server zabbix-agent apache2

6.4登录验证

浏览器登录：http://172.31.0.101/zabbix/setup.php

时区出错：

解决时区问题：

前面配置不生效，是放错地方，更改如下：

[root@zabbix-server ~]#vim /etc/zabbix/apache.conf  

 <IfModule mod_php7.c>

        php_value max_execution_time 300

        php_value memory_limit 128M

        php_value post_max_size 16M

        php_value upload_max_filesize 2M

        php_value max_input_time 300

        php_value max_input_vars 10000

        php_value always_populate_raw_post_data -1

        # php_value date.timezone Europe/Riga 

        php_value date.timezone Asia/Shanghai   #加这一行

重启

[root@zabbix-server ~]#systemctl restart zabbix-server zabbix-agent apache2

浏览器再次登录：http://172.31.0.101/zabbix/setup.php

下一步，配置数据库

zabbix server配置
