服务器：centos7

zabbix：4.0

一、安装部署数据库

本文使用MySQL5.7，如果服务器上有数据库跳过此步骤

下载安装数据库repo文件

wget https://dev.mysql.com/get/mysql80-community-release-el7-2.noarch.rpm

rpm -ivh mysql80-community-release-el7-2.noarch.rpm

修改repo文件将默认的8.0版本改成5.7

vi etc/yum.repos.d/mysql-community.repo

# Enable to use MySQL 5.7
[mysql57-community]
name=MySQL 5.7 Community Server
baseurl=http://repo.mysql.com/yum/mysql-5.7-community/el/7/$basearch/
enabled=0
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql


[mysql80-community]
name=MySQL 8.0 Community Server
baseurl=http://repo.mysql.com/yum/mysql-8.0-community/el/7/$basearch/
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql

改为下面的，也就是说启用mysql5.7的版本

# Enable to use MySQL 5.7
[mysql57-community]
name=MySQL 5.7 Community Server
baseurl=http://repo.mysql.com/yum/mysql-5.7-community/el/7/$basearch/
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql


[mysql80-community]
name=MySQL 8.0 Community Server
baseurl=http://repo.mysql.com/yum/mysql-8.0-community/el/7/$basearch/
enabled=0
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql

查看修改好的版本

yum list |grep mysql

mysql-community-client.x86_64 5.7.26-1.el7 mysql57-community

安装MySQL

yum -y install mysql-community-server.x86_64

启动数据库并设置开机自启动

[root@localhost ~]# systemctl start mysqld

[root@localhost ~]# systemctl enable mysqld

查看mysql密码

[root@localhost ~]# cat var/log/mysqld.log |grep "pass"

2019-07-09T08:39:30.367236Z 1 [Note] A temporary password is generated for root@localhost: pjjAa4zYy9!_

记住初始密码登录并修改密码

[root@localhost ~]# mysql -u root -p'pjjAa4zYy9!_'

mysql: [Warning] Using a password on the command line interface can be insecure.

mysql>  
mysql> ALTER USER USER() IDENTIFIED BY 123456';

mysql> flush privileges;

二、安装zabbix

rpm -Uvh https://repo.zabbix.com/zabbix/4.0/rhel/7/x86_64/zabbix-release-4.0-1.el7.noarch.rpm

yum clean all

安装Zabbix服务器，前端，代理

yum -y install zabbix-server-mysql zabbix-web-mysql zabbix-agent

创建数据库

mysql> create database zabbix character set utf8 collate utf8_bin;
Query OK, 1 row affected (0.00 sec)
mysql> grant all privileges on zabbix.* to zabbix@localhost identified by '123456';
Query OK, 0 rows affected, 1 warning (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

导入数据

[root@localhost ~]# zcat usr/share/doc/zabbix-server-mysql-4.0.10/create.sql.gz | mysql -uzabbix -p'123456'

mysql: [Warning] Using a password on the command line interface can be insecure.

ERROR 1046 (3D000) at line 1: No database selected

直接导入会报错

需要编辑下文件

//1,.备份
[root@localhost ~]# cd usr/share/doc/zabbix-server-mysql-4.0.11/
[root@localhost zabbix-server-mysql-4.0.11]# ls
AUTHORS  ChangeLog  COPYING  create.sql.gz  NEWS  README
[root@localhost zabbix-server-mysql-4.0.11]# cp create.sql.gz create.sql.gz.back
[root@localhost zabbix-server-mysql-4.0.11]# ls
AUTHORS  ChangeLog  COPYING  create.sql.gz  create.sql.gz.back  NEWS  README
//2,解压数据库


[root@localhost zabbix-server-mysql-4.0.11]# gunzip create.sql.gz
//3，安装nano编辑数据库信息


[root@localhost zabbix-server-mysql-4.0.11]# yum -y install nano
[root@localhost zabbix-server-mysql-4.0.11]# nano create.sql
//在第一行加上


USE zabbix；
//然后重新导入库即可


[root@localhost zabbix-server-mysql-4.0.11]# cat create.sql | mysql -uzabbix -p'XXXXX' zabbix

nano图形界面

保存

编写配置文件

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

[root@localhost ~]# cat /etc/zabbix/zabbix_server.conf |grep -Pv "^(#|$)"
